Clin Exp Dermatol. 2024 Apr 15:llae135. doi: 10.1093/ced/llae135. Online ahead of print.

ABSTRACT

BACKGROUND: No trial of supramolecular salicylic acid (SSA) for chloasma is available yet.

OBJECTIVE: The purpose of this study was to assess the efficacy and safety of Bole DA 30% supramolecular salicylic acid (SSA) combined with 10% niacinamide in treating chloasma.

METHODS: This multicenter (n=15), randomized, double-blind, parallel placebo-controlled trial randomized the subjects (1:1) to Bole DA 30% SSA or placebo. The primary endpoint was the effective rate after 16 weeks using the modified melasma area severity index (mMASI) [(pretreatment-posttreatment)/pretreatment×100%].

RESULTS: This study randomized 300 subjects (150/group in the full analysis set, 144 and 147 in the per-protocol set). The total mMASI score, overall Griffiths 10 score, left Griffiths 10 score, and right Griffiths 10 score were significantly lower in the Bole DA 30% SSA group than in the placebo group (all P<0.001). One study drug-related AE and one study drug-unrelated adverse events (AE) were reported in the Bole DA 30% SSA group. No AE was reported in the placebo group.

CONCLUSION: Bole DA 30% SSA combined with 10% niacinamide is effective and safe for treating chloasma.

Neurological adverse effects of isoxazoline exposure in cats and dogs

Mon, 2024-04-15 06:00

Vet Rec. 2024 Apr 14:e4149. doi: 10.1002/vetr.4149. Online ahead of print.

ABSTRACT

BACKGROUND: Isoxazolines are rarely reported to be associated with neurological adverse events in cats and dogs, but information about the onset and duration of neurological signs is lacking in the summary of product characteristics of these medicines.

METHODS: The Veterinary Poisons Information Service and the Dutch Poisons Information Center databases were searched using the Veterinary Dictionary for Drug-Related Affairs terms for ataxia, muscle tremor, convulsions or hyperesthesia in cats and dogs exposed to isoxazolines.

RESULTS: There were 22 cases with and 57 cases without outcome information, mostly involving fluralaner or sarolaner. In both groups, muscle tremors and convulsions were the most common signs. In dogs, neurological signs occurred with oral therapeutic dose and overdosage. In cats, most fluralaner cases involved therapeutic topical exposure, and all sarolaner cases involved oral exposure. In all cases with outcome information, the animals recovered.

LIMITATIONS: Cases discussed with poison centres tend to involve more severe signs.

CONCLUSION: The true incidence of neurological adverse effects from isoxazolines remains unclear. The delay between the administration and onset of signs can be long, and the association may be missed. A lack of timing information in the summary of product characteristics could also contribute to missed attribution of adverse effects.

Drug-induced bradycardia

Sat, 2024-04-13 06:00

Clin Med (Lond). 2023 Mar;23(2):173-174. doi: 10.7861/clinmed.2022-0431.

ABSTRACT

A 45-year-old woman presented to the hospital with bloody diarrhoea and significant weight loss over the past 1 month. On admission and evaluation, she was found to have acute ulcerative colitis. She was started on prednisolone and mesalamine therapy. Within 24 hours of initiation of this therapy, the patient complained of giddiness and chest discomfort and was found to have sinus bradycardia on ECG with no acute coronary event. After withdrawing mesalamine, her heart rate normalised within 24 hours and she remained symptom-free. This is a rare case report of severe symptomatic sinus bradycardia due to mesalamine therapy; to our knowledge, only four cases of mesalamine-induced bradycardia have been reported in the literature.

Immune-Related Adverse Events Due to Cancer Immunotherapy: Immune Mechanisms and Clinical Manifestations

Sat, 2024-04-13 06:00

Cancers (Basel). 2024 Apr 8;16(7):1440. doi: 10.3390/cancers16071440.

ABSTRACT

The landscape of cancer treatment has undergone a significant transformation with the introduction of Immune Checkpoint Inhibitors (ICIs). Patients undergoing these treatments often report prolonged clinical and radiological responses, albeit with a potential risk of developing immune-related adverse events (irAEs). Here, we reviewed and discussed the mechanisms of action of ICIs and their pivotal role in regulating the immune system to enhance the anti-tumor immune response. We scrutinized the intricate pathogenic mechanisms responsible for irAEs, arising from the evasion of self-tolerance checkpoints due to drug-induced immune modulation. We also summarized the main clinical manifestations due to irAEs categorized by organ types, detailing their incidence and associated risk factors. The occurrence of irAEs is more frequent when ICIs are combined; with neurological, cardiovascular, hematological, and rheumatic irAEs more commonly linked to PD1/PD-L1 inhibitors and cutaneous and gastrointestinal irAEs more prevalent with CTLA4 inhibitors. Due to the often-nonspecific signs and symptoms, the diagnosis of irAEs (especially for those rare ones) can be challenging. The differential with primary autoimmune disorders becomes sometimes intricate, given the clinical and pathophysiological similarities. In conclusion, considering the escalating use of ICIs, this area of research necessitates additional clinical studies and practical insights, especially the development of biomarkers for predicting immune toxicities. In addition, there is a need for heightened education for both clinicians and patients to enhance understanding and awareness.

Comparison of the Efficacy of Zoledronate and Denosumab in Patients with Acute Osteoporotic Vertebral Compression Fractures: A Randomized Controlled Trial

Sat, 2024-04-13 06:00

J Clin Med. 2024 Apr 1;13(7):2040. doi: 10.3390/jcm13072040.

ABSTRACT

Background: The comparison of the efficacy of zoledronate and denosumab for treating osteoporosis is controversial, and few randomized controlled trials have compared these two drugs in practical patients with acute osteoporotic vertebral compression fractures (OVCFs). We conducted a randomized controlled study to compare the efficacy of zoledronate and denosumab in patients with acute OVCF, with a focus on the occurrence of new OVCF. Methods: We enrolled 206 subjects who had their first acute OVCF, without any previous history of osteoporosis medication. The patients were randomly assigned to receive either intravenous zoledronate once a year or subcutaneous denosumab twice a year. We investigated the OVCF recurrence, clinical outcome, bone mineral density (BMD), and bone turnover markers over 12 months. Results: The final cohort comprised 89 participants (mean age of 75.82 ± 9.34 years, including 74 women [83.15%]) in the zoledronate group and 86 patients (mean age of 75.53 ± 10.23 years, including 71 women [82.56%]) in the denosumab group. New OVCFs occurred in 8 patients (8.89%) in the zoledronate group and 11 patients (12.79%) in the denosumab group (odds ratio, 1.485 [95% confidence interval, 0.567-3.891], p = 0.419). No significant difference was observed in the survival analysis between the two groups (p = 0.407). The clinical outcome, including the visual analog scale score for pain and simple radiographic findings, did not differ between the two groups. The changes in BMD and bone turnover markers were also not significantly different between the two groups. Additionally, drug-related adverse events did not differ between the groups in terms of safety. Conclusions: The efficacy of zoledronate was comparable to that of denosumab in terms of the occurrence of new OVCFs, as well as of the overall clinical course in patients with their first acute OVCF. Notably, this study represents the first comparison of these two drugs in patients with acute OVCF. However, further research with large-scale and long-term follow-up is necessary.

Evaluating Community-Based Intrathecal Baclofen Therapy: Effectiveness, Safety, and Feasibility

Sat, 2024-04-13 06:00

J Clin Med. 2024 Mar 22;13(7):1840. doi: 10.3390/jcm13071840.

ABSTRACT

Background: Intrathecal baclofen (ITB) is used for the treatment of intractable spasticity. The burden of traveling for ITB screening and aftercare is problematic for nursing home residents with severe spasticity and seems to result in undertreatment of spasticity. The aim of this study is to evaluate the effectiveness, safety, and feasibility of ITB for nursing home residents treated in their home, describing the selection phase, the initial trial of ITB, and aftercare up to 3 months after implantation of an ITB pump. Methods: This retrospective database study included immobile, adult nursing home residents with severe spasticity, referred to an Ambulatory Care Clinic between 2016 and 2021. When eligible, an ITB trial was performed by ITB experts in the nursing home. If a permanent pump was implanted, dose titration and aftercare were performed on location. Results: A total of 102 patients were referred; 80 underwent an ITB trial on location, and 94% improved significantly on the Modified Ashworth Scale and clonus scale pre-ITB trial versus post-ITB trial, as well as at 3 months post-implantation. There was a low incidence of adverse events, mostly procedure- and drug-related. Conclusions: This study indicates that selection, testing, and aftercare for ITB on location is effective and safe.

Outpatient geriatric health care in the German federal state of Mecklenburg-Western Pomerania: a population-based spatial analysis of claims data

Fri, 2024-04-12 06:00

BMC Health Serv Res. 2024 Apr 12;24(1):458. doi: 10.1186/s12913-024-10888-2.

ABSTRACT

BACKGROUND: Due to unidentified geriatric needs, elderly patients have a higher risk for developing chronic conditions and acute medical complications. Early geriatric screenings and assessments help to identify geriatric needs. Holistic and coordinated therapeutic approaches addressing those needs maintain the independence of elderly patients and avoid adverse effects. General practitioners are important for the timely identification of geriatric needs. The aims of this study are to examine the spatial distribution of the utilization of outpatient geriatric services in the very rural Federal State of Mecklenburg-Western Pomerania in the Northeast of Germany and to identify regional disparities.

METHODS: Geographical analysis and cartographic visualization of the spatial distribution of outpatient geriatric services of patients who are eligible to receive basic geriatric care (BGC) or specialized geriatric care (SGC) were carried out. Claims data of the Association of Statutory Health Insurance Physicians in Mecklenburg-Western Pomerania were analysed on the level of postcode areas for the quarter periods between 01/2014 and 04/2017. A Moran's I analysis was carried out to identify clusters of utilization rates.

RESULTS: Of all patients who were eligible for BGC in 2017, 58.3% (n = 129,283/221,654) received at least one BCG service. 77.2% (n = 73,442/95,171) of the patients who were eligible for SGC, received any geriatric service (BGC or SGC). 0.4% (n = 414/95,171) of the patients eligible for SGC, received SGC services. Among the postcode areas in the study region, the proportion of patients who received a basic geriatric assessment ranged from 3.4 to 86.7%. Several regions with statistically significant Clusters of utilization rates were identified.

CONCLUSIONS: The widely varying utilization rates and the local segregation of high and low rates indicate that the provision of outpatient geriatric care may depend to a large extent on local structures (e.g., multiprofessional, integrated networks or innovative projects or initiatives). The great overall variation in the provision of BGC services implicates that the identification of geriatric needs in GPs' practices should be more standardized. In order to reduce regional disparities in the provision of BGC and SGC services, innovative solutions and a promotion of specialized geriatric networks or healthcare providers are necessary.

A cross-sectional study on personal values of medical students: the differences from their instructors, their associations with mental wellbeing, and the influences of gender

Fri, 2024-04-12 06:00

BMC Psychiatry. 2024 Apr 12;24(1):272. doi: 10.1186/s12888-024-05695-2.

ABSTRACT

BACKGROUND: Personal values of Thai medical students have been observed to be diverging from those of their seniors, but the differences remain uncharacterized. Despite its potential association with mental wellbeing, the issue remain unexplored in the population. This study aimed to explore (1) the difference in personal values between medical students and instructors and (2) the association between student's value adherence to mental well-being and the interaction by gender.

METHODS: An online survey was performed in 2022. Participants rated their adherence to five groups of values, namely, Self-Direction, Hedonism, Achievement & Power, Universalism & Benevolence, and Tradition. Participants also rated their mental wellbeing. Comparisons were made between the personal values of students and instructors. The association between the personal values of students and their mental wellbeing and the interaction between values and gender were analyzed in linear regression.

RESULTS: Compared to instructors, students rated higher on Universalism & Benevolence, marginally higher on Hedonism, and lower on Tradition. Students' ratings on Self-Direction, Universalism & Benevolence, and Tradition predicted better mental wellbeing. Their rating on Hedonism predicted poorer mental wellbeing, the effect of which was marginally stronger in males. Ratings on Achievement & Power marginally predicted poorer mental wellbeing in females.

CONCLUSION: Difference in personal values between medical students and instructors have been observed. Some of these values hold potentials over student's mental wellbeing. Curricular and medical school environmental accommodation for the changes in the characters of learners may be necessary to mitigate the adverse effects on their mental wellbeing and foster development of desirable professional characteristics.

Unfractionated heparin reverses aspirin inhibition of platelets during coronary artery bypass graft surgery

Fri, 2024-04-12 06:00

Sci Rep. 2024 Apr 13;14(1):8572. doi: 10.1038/s41598-024-58005-x.

ABSTRACT

Unfractionated heparin (UFH) is an effective antithrombotic during surgery but has known adverse effects, in particular on platelets. A marked increase in platelet responsiveness has previously been observed in patients within minutes of receiving UFH, despite adequate inhibition by aspirin prior to heparin. We studied this phenomenon in patients undergoing cardiac artery bypass grafting (n = 17) to determine whether the effects of heparin were systemic or platelet-specific. All patients' platelets were fully inhibited by aspirin prior to surgery, but within 3 min of receiving heparin spontaneous aggregation and responses to arachidonic acid (AA) and ADP increased significantly (p ≥ 0.0002), and activated platelets were found in the circulation. While there was no rise in thromboxane in the plasma following heparin, levels of the major platelet 12-lipoxygenase product, 12-HETE, rose significantly. Mixing experiments demonstrated that the changes caused by heparin resided primarily in the platelets, while addition of AA pathway inhibitors, and analysis of oxylipins provided evidence that, following heparin, aggregating platelets regained their ability to synthesise thromboxane. These findings highlight potentially unrecognised pro-thrombotic and pro-inflammatory changes during CABG surgery, and provide further evidence of adverse effects associated with UFH.

Psychosis with use of amphetamine drugs, methylphenidate and atomoxetine in adolescent and adults

Fri, 2024-04-12 06:00

BMJ Ment Health. 2024 Apr 12;27(1):e300876. doi: 10.1136/bmjment-2023-300876.

ABSTRACT

BACKGROUND: Use of psychostimulants and relative drugs has increased worldwide in treatment of attention-deficit hyperactivity disorder (ADHD) in adolescents and adults. Recent studies suggest a potential association between use of psychostimulants and psychotic symptoms. The risk may not be the same between different psychostimulants.

OBJECTIVE: To assess whether amphetamine or atomoxetine use is associated with a higher risk of reporting symptoms of psychosis than methylphenidate use in adolescents and adults, particularly in patients with ADHD.

METHODS: Using VigiBase, the WHO's pharmacovigilance database, disproportionality of psychotic symptoms reporting was assessed among adverse drug reactions related to methylphenidate, atomoxetine and amphetamines, from January 2004 to December 2018, in patients aged 13-25 years. The association between psychotic symptoms and psychostimulants was estimated through the calculation of reporting OR (ROR).

FINDINGS: Among 13 863 reports with at least one drug of interest, we found 221 cases of psychosis with methylphenidate use, 115 with atomoxetine use and 169 with a prescription of an amphetamine drug. Compared with methylphenidate use, amphetamine use was associated with an increased risk of reporting psychotic symptoms (ROR 1.61 (95% CI 1.26 to 2.06)]. When we restricted the analysis to ADHD indication, we found a close estimate (ROR 1.94 (95% CI 1.43 to 2.64)). No association was found for atomoxetine.

CONCLUSION: Our study suggests that amphetamine use is associated with a higher reporting of psychotic symptoms, compared with methylphenidate use.

CLINICAL IMPLICATIONS: The prescription of psychostimulants should consider this potential adverse effect when assessing the benefit-risk balance.

Clinical course of mild-to-moderate idiopathic pulmonary fibrosis during therapy with pirfenidone: Results of the non-interventional study AERplus

Fri, 2024-04-12 06:00

Pneumologie. 2024 Apr;78(4):236-243. doi: 10.1055/a-2267-2074. Epub 2024 Apr 12.

ABSTRACT

INTRODUCTION: Pirfenidone was the first anti-fibrotic drug approved in Europe in 2011 for the treatment of mild-to-moderate idiopathic pulmonary fibrosis.

OBJECTIVES: To investigate the clinical course of mild-to-moderate idiopathic pulmonary fibrosis in pirfenidone-treated patients in a real-world setting.

METHODS: The non-interventional study was conducted at 18 sites in Germany from 6/2014-12/2016. Adult patients with mild-to-moderate idiopathic pulmonary fibrosis were treated with pirfenidone (escalated from 3×1 to 3×3 capsules of 267 mg/day within 3 weeks) for 12 months. The observation period comprised 4 follow-up visits at months 3, 6, 9 and 12. Disease progression was defined as decrease of ≥10% in vital capacity or ≥15% in diffusing capacity of the lung for carbon monoxide (DLCO) and/or ≥50m in 6-minute walking distance vs. baseline, or "lack of response/progression" as reason for therapy discontinuation.

RESULTS: A total of 51 patients (80.4% male, mean age 70.6 years) were included in the full analysis set. Disease progression at any visit was reported for 23 (67.6%) of 34 patients with available data. Over the course of the study, lung function parameters, physical resilience, impact of cough severity on quality of life, and the mean Gender, Age and Physiology Index (stage II) remained stable. In total, 29 patients (56.9%) experienced at least one adverse drug reaction (11 patients discontinued due to adverse drug reactions); serious adverse reactions were reported in 12 patients (23.5%).

CONCLUSIONS: The results of this study are in line with the established benefit-risk profile of pirfenidone. Therefore, pirfenidone can be considered a valuable treatment option to slow disease progression in mild-to-moderate idiopathic pulmonary fibrosis. NCT02622477.

The Effectiveness of a Digital App for Reduction of Clinical Symptoms in Individuals With Panic Disorder: Randomized Controlled Trial

Fri, 2024-04-12 06:00

J Med Internet Res. 2024 Apr 12;26:e51428. doi: 10.2196/51428.

ABSTRACT

BACKGROUND: Panic disorder is a common and important disease in clinical practice that decreases individual productivity and increases health care use. Treatments comprise medication and cognitive behavioral therapy. However, adverse medication effects and poor treatment compliance mean new therapeutic models are needed.

OBJECTIVE: We hypothesized that digital therapy for panic disorder may improve panic disorder symptoms and that treatment response would be associated with brain activity changes assessed with functional near-infrared spectroscopy (fNIRS).

METHODS: Individuals (n=50) with a history of panic attacks were recruited. Symptoms were assessed before and after the use of an app for panic disorder, which in this study was a smartphone-based app for treating the clinical symptoms of panic disorder, panic symptoms, depressive symptoms, and anxiety. The hemodynamics in the frontal cortex during the resting state were measured via fNIRS. The app had 4 parts: diary, education, quest, and serious games. The study trial was approved by the institutional review board of Chung-Ang University Hospital (1041078-202112-HR-349-01) and written informed consent was obtained from all participants.

RESULTS: The number of participants with improved panic symptoms in the app use group (20/25, 80%) was greater than that in the control group (6/21, 29%; χ21=12.3; P=.005). During treatment, the improvement in the Panic Disorder Severity Scale (PDSS) score in the app use group was greater than that in the control group (F1,44=7.03; P=.01). In the app use group, the total PDSS score declined by 42.5% (mean score 14.3, SD 6.5 at baseline and mean score 7.2, SD 3.6 after the intervention), whereas the PDSS score declined by 14.6% in the control group (mean score 12.4, SD 5.2 at baseline and mean score 9.8, SD 7.9 after the intervention). There were no significant differences in accumulated oxygenated hemoglobin (accHbO2) at baseline between the app use and control groups. During treatment, the reduction in accHbO2 in the right ventrolateral prefrontal cortex (VLPFC; F1,44=8.22; P=.006) and the right orbitofrontal cortex (OFC; F1,44=8.88; P=.005) was greater in the app use than the control group.

CONCLUSIONS: Apps for panic disorder should effectively reduce symptoms and VLPFC and OFC brain activity in patients with panic disorder. The improvement of panic disorder symptoms was positively correlated with decreased VLPFC and OFC brain activity in the resting state.

Exploratory mass cytometry analysis reveals immunophenotypes of cancer treatment-related pneumonitis

Fri, 2024-04-12 06:00

Elife. 2024 Apr 12;12:RP87288. doi: 10.7554/eLife.87288.

ABSTRACT

Anticancer treatments can result in various adverse effects, including infections due to immune suppression/dysregulation and drug-induced toxicity in the lung. One of the major opportunistic infections is Pneumocystis jirovecii pneumonia (PCP), which can cause severe respiratory complications and high mortality rates. Cytotoxic drugs and immune-checkpoint inhibitors (ICIs) can induce interstitial lung diseases (ILDs). Nonetheless, the differentiation of these diseases can be difficult, and the pathogenic mechanisms of such diseases are not yet fully understood. To better comprehend the immunophenotypes, we conducted an exploratory mass cytometry analysis of immune cell subsets in bronchoalveolar lavage fluid from patients with PCP, cytotoxic drug-induced ILD (DI-ILD), and ICI-associated ILD (ICI-ILD) using two panels containing 64 markers. In PCP, we observed an expansion of the CD16+ T cell population, with the highest CD16+ T proportion in a fatal case. In ICI-ILD, we found an increase in CD57+ CD8+ T cells expressing immune checkpoints (TIGIT+ LAG3+ TIM-3+ PD-1+), FCRL5+ B cells, and CCR2+ CCR5+ CD14+ monocytes. These findings uncover the diverse immunophenotypes and possible pathomechanisms of cancer treatment-related pneumonitis.

Delayed immune-related adverse events in long-responders of immunotherapy: a single-center experience

Fri, 2024-04-12 06:00

Asia Pac J Clin Oncol. 2024 Apr 12. doi: 10.1111/ajco.14059. Online ahead of print.

ABSTRACT

BACKGROUND: Immune-checkpoint inhibitors (ICIs) often cause immune-related adverse events (irAEs). The spectrum of irAEs and their managements has been partially clarified, however the knowledge on time-course of irAEs is not well understood.

METHODS: A retrospective study based on the medical record was performed. The study subjects were consisting of patients with various types of solid tumors for whom ICIs (nivolumab, pembrolizumab, durvalumab, atezolizumab, nivolumab plus ipilimumab) were used between April 2016 and October 2021. We focused on irAEs developed more than 1-year after commencement ICIs (delayed irAE group) and compared with irAEs developed within 1-year (non-delayed irAE group) in terms of types and severity of irAEs.

RESULTS: A total of 336 patients were enrolled in the study. Eighty-eight patients (26.2%) developed irAEs and 248 did not. Most of the patients developing irAEs were treated using PD-L1/PD-1 inhibitors. Eighty-one patients (24.1%) in non-delayed irAE group and 7 patients (2.1%) in delayed irAE group developed irAEs. The median onset of irAEs in the delayed irAE group was 18.6 months (range: 13.5-24.3). The types of irAEs observed in delayed irAE group were dermatitis (2 cases), pneumonitis (2 cases), nephritis (1 case), arthritis (1 case), and gastritis (1 case). The severity of irAEs was almost mild (≤G2), but one patient (.3%) developed G3 nephritis.

CONCLUSION: PD-L1/PD-1 inhibitors frequently caused various irAEs but their severities were mostly tolerable. Few patients developed delayed irAE with mild toxities.

Apilimod dimesylate in C9orf72 amyotrophic lateral sclerosis: a randomized phase 2a clinical trial

Fri, 2024-04-12 06:00

Brain. 2024 Apr 12:awae109. doi: 10.1093/brain/awae109. Online ahead of print.

ABSTRACT

Apilimod dimesylate is a first-in-class phosphoinositide kinase, FYVE-type zinc finger containing (PIKfyve) inhibitor with favourable clinical safety profile and has demonstrated activity in preclinical C9orf72 and TDP-43 amyotrophic lateral sclerosis models. In this amyotrophic lateral sclerosis clinical trial, the safety, tolerability, CNS penetrance, and modulation of pharmacodynamic target engagement biomarkers were evaluated. This Phase 2a, randomized, double-blind, placebo-controlled, biomarker-endpoint clinical trial was conducted in four USA centres (ClinicalTrials.gov NCT05163886). Participants with C9orf72 repeat expansion were randomly assigned (2:1) to receive twice-daily oral treatment of 125 mg apilimod dimesylate capsules or matching placebo for 12 weeks, followed by a 12-week open-label extension. Safety was measured as the occurrence of treatment-emergent adverse or serious adverse events attributable to study drug, and tolerability as trial completion on treatment over 12 weeks. Changes from baseline in plasma and CSF and concentrations of apilimod and its active metabolites and of pharmacodynamic biomarkers of PIKfyve inhibition (soluble glycoprotein nonmetastatic melanoma protein B [sGPNMB] upregulation) and disease-specific CNS target engagement (poly[GP]). Between Dec 16, 2021, and Jul 7, 2022, 15 eligible participants were enrolled. There were no drug-related serious adverse events reported in the trial. Fourteen (93%) participants completed the double-blind period with 99% dose compliance (N=9 [90%] apilimod dimesylate; N=5 [100%] placebo). At Week 12, apilimod dimesylate was measurable in CSF at 1.63 ng/mL (SD: 0.937). At Week 12, apilimod dimesylate increased plasma sGPNMB by > 2.5-fold (p < 0.001) indicating PIKfyve inhibition and lowered CSF poly(GP) protein levels by 73% (p < 0.001) indicating CNS tissue-level proof of mechanism. Apilimod dimesylate met prespecified key safety and biomarker endpoints in this Phase 2a trial and demonstrated CNS penetrance and pharmacodynamic target engagement. Apilimod dimesylate was observed to have the greatest reduction in CSF poly(GP) levels observed to date in C9orf72 clinical trials.

BACKGROUND: Oral testosterone undecanoate (TU) formulations may provide effective, safe, and easily titratable testosterone replacement therapy.

OBJECTIVE: Demonstrate efficacy and safety of a novel oral TU formulation.

DESIGN: An open-label, single-arm, multi-center trial treated 155 hypogonadal men for 180 days. Treatment began at 200 mg TU twice daily with meals; doses were titrated over two 28-day cycles to between 100 and 800 mg TU daily, measuring average testosterone (T Cavg) after 90 days. Ambulatory blood pressure monitoring (ABPM) occurred at baseline, 120, and 180 days.

METHODS: Titrations used a randomized blood sample taken 3-, 4-, or 5-h post-morning dose. Outcomes used sodium fluoride/ethylenediaminetetraacetate plasma testosterone (T) values; serum results were also reported. Blood pressure (ABPM and in-clinic) was evaluated for change from baseline.

RESULTS: After titration, 87.8% of KYZATREX™ treated participants (worse-case scenario) and 96.1% of 90-day completers achieved eugonadal mean plasma T values. Serum T Cavg was 452 ng/dL and maximum T concentrations (T Cmax) met all FDA criteria. Participant eugonadal percentages were comparable across subgroups for age, weight, and body mass index. Diet had no effect on participant eugonadal percentages. KYZATREX was well tolerated, with no drug-related serious adverse events (SAE) and one adverse drug reaction (hypertension) observed in 2% or more of participants. Systolic ambulatory blood pressure increased 1.7 mmHg (95% confidence interval: 0.3-3.1). At baseline, 36% of 155 participants were receiving anti-hypertensive medication and 22% were diabetic. No dose increases occurred in existing anti-hypertensive medication; five participants (3.2%) started anti-hypertensive medication.

CONCLUSION: KYZATREX provided safe and effective testosterone levels within the normal range in hypogonadal male study participants.

Steroid Premedication Might Protect From Postoperative Erythema Nodosum Leprosum in Leprosy: A Case Report

Fri, 2024-04-12 06:00

Cureus. 2024 Mar 11;16(3):e55986. doi: 10.7759/cureus.55986. eCollection 2024 Mar.

ABSTRACT

Leprosy is known for its diverse pathophysiologic involvement and resulting multisystemic manifestation and morbidities. Despite global efforts to eliminate this public health illness, it is still prevalent in some Asian and European countries. Perioperative management of a leprosy patient is challenging owing to the indirect and direct involvement of the airway, respiratory, and cardiac systems; treatment-related side-effects involving the hepato-renal systems affecting the anesthesia techniques and drugs pharmacokinetic and pharmacodynamics. While anaesthesiologists are aware of such happenings and often tailor the anesthesia management for the concerning issues, immunological aspects of the disease and drug-related adverse events are less enquired about, such as type-2 lepra reaction, i.e., erythema nodosum leprosum (ENL), etc. Further, data on perioperative ENL management and prevention are still being determined. We report one case of a 52-year-old female who underwent gynecology surgery and developed ENL on the third postoperative day, which was managed using Steroids. Unfortunately, the patient had a surgical site infection, which required another surgery within the month, while the patient was still under the steroid successfully without any adverse events. Although a single case cannot provide causation or association, the case is presented to highlight the probable preventive action of steroids on the occurrence of postoperative ENL, where surgical stress is considered a risk factor.

Development of a predictive model for hypoxia due to sedatives in gastrointestinal endoscopy: a prospective clinical study in Korea

Fri, 2024-04-12 06:00

Clin Endosc. 2024 Apr 12. doi: 10.5946/ce.2023.198. Online ahead of print.

ABSTRACT

BACKGROUND/AIMS: Sedation has become a standard practice for patients undergoing gastrointestinal (GI) endoscopy. However, considering the serious cardiopulmonary adverse events associated with sedatives, it is important to identify patients at high risk. Machine learning can generate reasonable prediction for a wide range of medical conditions. This study aimed to evaluate the risk factors associated with sedation during GI endoscopy and develop a predictive model for hypoxia during endoscopy under sedation.

METHODS: This prospective observational study enrolled 446 patients who underwent sedative endoscopy at the Korea University Ansan Hospital. Clinical data were used as predictor variables to construct predictive models using the random forest method that is a machine learning algorithm.

RESULTS: Seventy-two of the 446 patients (16.1%) experienced life-threatening hypoxia requiring immediate medical intervention. Patients who developed hypoxia had higher body weight, body mass index (BMI), neck circumference, and Mallampati scores. Propofol alone and higher initial and total dose of propofol were significantly associated with hypoxia during sedative endoscopy. Among these variables, high BMI, neck circumference, and Mallampati score were independent risk factors for hypoxia. The area under the receiver operating characteristic curve for the random forest-based predictive model for hypoxia during sedative endoscopy was 0.82 (95% confidence interval, 0.79-0.86) and displayed a moderate discriminatory power.

CONCLUSIONS: High BMI, neck circumference, and Mallampati score were independently associated with hypoxia during sedative endoscopy. We constructed a model with acceptable performance for predicting hypoxia during sedative endoscopy.

Development and Feasibility Evaluation of Smart Cancer Care 2.0 Based on Patient-Reported Outcomes for Post-Discharge Management of Patients with Cancer

Fri, 2024-04-12 06:00

Cancer Res Treat. 2024 Apr 9. doi: 10.4143/crt.2024.003. Online ahead of print.

ABSTRACT

PURPOSE: A "Smart Cancer Care" platform that integrates patient-reported outcomes (PROs) with management has been established in Korea. This study focused on improving health behaviors and connecting patients to welfare services by introducing and assessing the feasibility of "Smart Cancer Care 2.0," an enhanced version designed for monitoring complications post-cancer treatment.

MATERIALS AND METHODS: Smart Cancer Care 2.0 was developed by conducting a literature review and consulting with expert panels to identify symptoms or variables requiring monitoring and management guidelines based on the treatment type. Qualitative and quantitative surveys were conducted to assess the feasibility of the app and web system based on the experiences of patients with cancer and healthcare workers.

RESULTS: A total of 81 symptoms or variables (chemotherapy-, surgery-, radiotherapy-, rehabilitation-, and health management-related) were selected for management in Smart Cancer Care 2.0. PROs for these symptoms were basically categorized into three severity grades: (1) preventive management, (2) self-treatment, and (3) consultation with a healthcare worker or visit to a healthcare institution. The overall mean scores in the feasibility evaluation by patients and healthcare workers were 3.83 and 3.90 points, respectively, indicating high usefulness.

CONCLUSION: Smart Cancer Care 2.0 leverages the existing ICT-based platform, Smart Cancer Care, and further includes health behaviors and welfare services. Smart Cancer Care 2.0 may play a crucial role in establishing a comprehensive post-discharge management system for patients with cancer as it provides suitable interventions based on patients' responses and allows the regularly collected PROs to be easily viewed for streamlined care.

Predictors of severe hepatotoxicity among retroviral infected adults on HAART regimen in Ilubabor Zone, Southwest Ethiopia

Thu, 2024-04-11 06:00

Sci Rep. 2024 Apr 11;14(1):8473. doi: 10.1038/s41598-024-57900-7.

ABSTRACT

Nearly half of the deaths among hospitalized human immuno deficiency virus-infected patients in the highly active antiretroviral therapy era have been attributed to liver disease. This may range from an asymptomatic mild increase of liver enzymes to cirrhosis and liver failure. Different works of literature elucidated both retroviral infection and the adverse effects of highly active antiretroviral therapy as a cause of hepatotoxicity. Individual adaptations to medications and environmental exposures, shaped by cultural norms and genetic predispositions, could potentially modulate the risk and progression of liver disease in this population. Therefore, this study aims to assess the predictors of severe hepatotoxicity in retroviral-infected adults receiving highly active antiretroviral therapy regimens within the Ilubabor Zone, Southwest Ethiopia. A facility-based cross-sectional study was conducted among adult retroviral-infected patients in five selected anti-retro virus therapy clinics from May1 to July 30/2022. A systematic sampling technique was used to select 457 study participants and Binary logistic regression statistical data analysis was used, P value < 0.05 was considered statistically significant. The prevalence of severe hepatotoxicity was 21.44% in the study population. CD+4 count < 200 cells/mm3 (AOR = 2.19, 95% CI 1.04-5.22, P = 0.01), human immunodeficiency virus co-infection with tuberculosis (AOR = 2.82, 95% CI 1.01-8.29, P = 0.03) and human immuno deficiency virus co-infection with hepatitis-B/hepatitis C virus (AOR = 5.02, 95% CI 1.82-16.41) were predictors of severe hepatotoxicity. The magnitude of severe hepatotoxicity was high among adult retroviral-infected patients on highly active anti-retroviral drug regimens. Co-infection of human immuno deficiency virus with hepatitis B virus or hepatitis C virus, tuberculosis and CD4+T-cell count below 200 cells/mm3 were predictors of severe hepatotoxicity. Therefore, HIV patients on highly active antiretroviral therapy require close attention and regular monitoring of their liver function.
