Lecanemab's Path Forward: Navigating the Future of Alzheimer's Treatment in Europe Amidst the EMA's Rejection.

Lecanemab (Leqembi©, Biogen), a humanized anti-amyloid-beta monoclonal antibody, has been approved for early-stage Alzheimer's disease (AD) in several countries, including the US and Japan. However, the European Medicines Agency (EMA) recently issued a negative opinion on its marketing authorization, reflecting concerns over the clinical value and manageability of anti-amyloid treatments. This decision highlights the ongoing disconnect between research advancements and clinical practice, where the focus on biological markers over tangible clinical improvements remains contentious. Despite promising biological effects, lecanemab's clinical outcomes have been modest, raising questions about its therapeutic role. The EMA's refusal underscores the need to address doubts surrounding the real-world effectiveness and safety of such treatments, especially concerning amyloid-related imaging abnormalities (ARIAs), a common side effect observed in clinical trials. The recent approval of lecanemab by the UK's Medicines and Healthcare products Regulatory Agency, despite the National Institute for Health and Care Excellence's rejection on cost-effectiveness grounds, further fuels the debate on the feasibility of anti-amyloid therapies. This commentary emphasizes the importance of real-world data on lecanemab's impact on cognitive decline, daily functioning, and side-effect management. As the global clinical use of lecanemab increases, continuous and standardized reporting on its outcomes is crucial for guiding future regulatory decisions and for potentially bridging the gap between research and practice in AD treatment.

Paracetamol is both a friend and a foe: What should a pediatrician know? A clinical case

One of the most common drug-related side effects is hepatotoxicity. The most common cause of severe drug-induced liver injury is acetaminophen (paracetamol), as it is an over-the-counter drug. Paracetamol is safe and effective in children and adolescents at therapeutic doses; however, it is the leading cause of acute liver failure in children (21% of cases) and adults (40%) with overdose. The clinical presentation of toxic liver damage depends on the time elapsed after taking paracetamol and its dose. Symptoms of liver damage are not always obvious but can develop rapidly from day 2 to day 5 after poisoning. The article presents a clinical case of an unintentional overdose of paracetamol in a teenage girl due to non-compliance with the dose and regimen.

A prospective randomized-controlled non-blinded comparative study of the JAK inhibitor (baricitinib) with TNF-α inhibitors and conventional DMARDs in a sample of Egyptian rheumatoid arthritis patients.

To evaluate the efficacy of baricitinib compared to TNF-α Inhibitors and conventional DMARDs (cDMARDs) in patients with RA. Our study included 334 RA patients classified into 3 groups: the first receiving baricitinib, the second receiving TNF-α Inhibitors, and the third receiving cDMARDs. Patients were evaluated at baseline, week 12, and week 24 using TJC, SJC, VAS, DAS28, CDAI, and HAQ-DI. Larsen score was measured at baseline and 24weeks. The response to therapy was assessed at weeks 12 and 24 using ACR 20, ACR 50, and ACR 70 response criteria. Emerging treatment side effects were monitored. Patients receiving baricitinib showed significant improvement regarding all outcome measures at weeks 12 and 24. In addition, baricitinib was comparable to TNF Inhibitors in all outcome measures except the ACR 70 at week 12, which was higher in the baricitinib group. Furthermore, baricitinib group showed significantly better outcome measures and response to therapy in comparison to cDMARDs group. The most common side effects in the baricitinib group were infection, GIT, and CVS complications. The most common side effects in the TNF inhibitors group were infection and skin complications. The cDMARDs had the least side effects, mostly GIT complications. Baricitinib is an effective drug for treating RA refractory to cDMARDs, improving disease activity measures and functional status and reducing the progression of structural joint damage. It has a comparable efficacy and safety profile to TNF Inhibitors. Multicenter studies are recommended to support our results. Key Points • Baricitinib is an effective therapeutic choice for rheumatoid arthritis refractory to cDMARDs. • Patients treated with baricitinib showed improvement in all outcome measures and functional status. • Bricitinib delayed the progression of radiographic joint damage more effectively than cDMARDs. • The efficacy and safety of baricitinib for treating rheumatoid arthritis is comparable to that of TNF inhibitors.

Immunogenicity and safety of DTPW-HEPB-HIB (PRP-T) vaccine (Pentavac) in infants aged 2–7 months: a post marketing phase 4 clinical trial study

Background.Vaccines play a critical role in safeguarding public health, particularly for children. It is imperative to proactively address safety concerns to uphold trust in their effectiveness and safety. Skepticism surrounding vaccines can have significant adverse effects on the overall well-being of the entire population, potentially leading to individuals opting out of vital vaccinations, thereby posing risks to public health. Thus, ensuring confidence in vaccine safety remains paramount.Materials and methods.This phase four clinical trial was conducted as a post-marketing study (PMS) on 2 to 7 month old healthy infants (N = 539) to evaluate immunity and safety of Indian pentavalent vaccine containing Diphtheria, Tetanus, Pertussis, Hepatitis B and Haemophilus influenza type b [DTPW-HEP B-HIB (PRP-T)/PENTAVAC] in four different centers at Tehran province. Blood samples were collected from eligible infants before receiving the vaccine (2 months of age) and 1 month after the third dose (7 months of age) to determine antibodies against all antigens in the pentavalent vaccine using ELISA.Results.The results indicated that the immune responses demonstrated seroprotection and protective antibody levels after three doses of the vaccine for Haemophilus influenza b, diphtheria, tetanus, hepatitis B virus andBordetella pertussiswere 99.1%, 98.7%, 99.8%, 99.4% and 69.6%, respectively. Statistical analysis showed that the P-value for all vaccine components was similar (P 0.001). The five most common side effects reported were mild fever (10%), erythema at the vaccination site (9.1%), inflammation (4.3%), pain at the vaccination site (3.3%), and restlessness (2.6%).Conclusion.This study’s findings demonstrated a significant increase in antibody levels against all five vaccine components. In light of these results, it can be concluded that the Pentavalent vaccine is not only effective in enhancing immunity against multiple diseases but also presents minimal risk of side effects in the study population. These findings contribute to the body of evidence supporting the safety and efficacy of vaccines, underscoring their crucial role in protecting public health.

PCSK9 Inhibitors: The Evolving Future.

PCSK9 inhibitors are a novel class of medications that lower LDL cholesterol (LDL-C) by increasing LDL receptor activity, promoting clearance of LDL-C from the bloodstream. Over the years, PCSK9 inhibitors have been explored as adjunct therapies to statins or as monotherapy in high-risk cardiovascular patients. This review aims to provide an updated perspective on PCSK9 inhibitors, assessing their clinical efficacy, safety, and significance, especially in light of recent clinical trials. The review examines the role of PCSK9 in cholesterol regulation and summarizes the results of major cardiovascular trials, including FOURIER, SPIRE-1, SPIRE-2, and ODYSSEY Outcomes. It also discusses emerging treatments like small interfering RNA (siRNA) therapies and evaluates PCSK9 inhibitor effects on LDL-C and lipoprotein(a) levels. Clinical trials have shown PCSK9 inhibitors reduce LDL-C by up to 60%. In the FOURIER trial, evolocumab reduced LDL-C by 59% and major cardiovascular events by 15%-20%. The SPIRE-2 trial, despite early termination, showed a 21% risk reduction in the primary composite endpoint with bococizumab. The ODYSSEY Outcomes trial reported a 57% LDL-C reduction with alirocumab, alongside a 15% reduction in adverse events. Emerging treatments like Inclisiran offer long-term LDL-C control with fewer doses. PCSK9 inhibitors are generally well-tolerated, with the most common side effect being injection site reactions. PCSK9 inhibitors significantly lower LDL-C and reduce cardiovascular events, offering promising therapies for high-risk patients, including those with familial hypercholesterolemia (FH) and those who cannot tolerate statins. Future research will focus on optimizing these inhibitors, integrating complementary therapies, and exploring gene-editing technologies to improve patient outcomes.

Isotretinoin-associated chronic diarrhea as a complication of systemic isotretinoin therapy

Objective: Isotretinoin is a synthetic derivative of vitamin A that is highly effective in treating acne vulgaris. Although its common side effects include skin dryness, photosensitivity, epistaxis, and depressive disorders, gastrointestinal side effects should also be considered, though they are less frequently highlighted. Case: We aim to present a 28-year-old female patient who developed chronic diarrhea and associated hypokalemic paralysis during isotretinoin treatment, prescribed for acne management. This case underlines the importance of recognizing gastrointestinal side effects, alongside the more commonly known adverse effects of isotretinoin. Conclusion: Chronic diarrhea is a rare but significant side effect of isotretinoin that may lead to serious complications such as hypokalemic paralysis. In this case, we demonstrated how isotretinoin can cause metabolic imbalances, even in relatively healthy young adults, by inducing diarrhea. While the association between isotretinoin and inflammatory bowel disease remains inconclusive, clinicians should remain vigilant regarding the gastrointestinal side effects of isotretinoin. Early recognition and discontinuation of the drug, combined with appropriate supportive treatments, are essential in preventing further complications. Dermatologists and gastroenterologists should collaborate in identifying patients at higher risk, such as those with pre-existing gastrointestinal conditions, and closely monitor for any adverse effects during isotretinoin treatment. Future studies, particularly large-scale randomized controlled trials, are needed to better understand the relationship between isotretinoin and gastrointestinal side effects.

Evaluation of the common skin diseases in patients with malignancies and the cutaneous side effects of cancer treatments

Purpose The diversity of skin diseases in patients with malignancies leads to diagnostic difficulties and complicate cancer treatment. Furthermore, the increasing use of chemotherapy drugs and novel treatment regimens raises the risk of the development of various cutaneous side effects and the need for dermatologists during cancer management. We investigated the skin diseases in patients with malignancies and the cutaneous side effects of cancer treatments. Methods Medical records of cancer patients evaluated in the Dermatology clinic between July 2018 and April 2023 were retrospectively reviewed. Results This study included 872 cancer patients, 374 females and 498 males. Acute myeloid leukaemia was the most common malignancy, followed by multiple myeloma and invasive ductal breast carcinoma. Graft versus host disease was observed in 89 (10.2%) patients after stem cell transplantation and radiodermatitis developed in 16 (1.8%) patients. Maculopapular drug eruption and hand foot syndrome were the most common cutaneous side effects of chemotherapy drugs. Capecitabine was the most common etiologic agent in hand foot syndrome. Cellulitis was the most frequent bacterial infection in cancer patients, whereas herpes zoster was the most frequent viral infection. Among the chemotherapy drugs that caused acneiform drug eruption, cetuximab and cytarabine were notable. Facial erythema was associated with cytarabine use in 27.3% of patients. Conclusion Identifying the common skin diseases in cancer patients and cutaneous side effects due to chemotherapy drugs may help to take preventive measures, develop specific and effective treatments, determine the most appropriate cancer treatment options, and increase patients’ compliance with cancer treatment.

Positioning Imatinib for Pulmonary Arterial Hypertension (PIPAH) study

Abstract Introduction Pulmonary arterial hypertension (PAH) is characterised by pre-capillary pulmonary vascular remodelling. Imatinib, a tyrosine kinase inhibitor, was the first treatment investigated in PAH patients with the primary aim of targeting vascular remodelling. A Phase 3 study showed that imatinib 400mg daily reduces pulmonary vascular resistance and increases exercise capacity but only 43% of patients continued the drug for 6 months. Concerns about safety prevented regulatory approval. Purpose To identify a safe and tolerated dose of oral Imatinib and evaluate efficacy in the dose range 100-400mg daily. Methods Oral Imatinib was added to the background therapy of 17 patients with PAH; prior intracranial haemorrhage was excluded by cross sectional imaging and none were receiving an anticoagulant. The first patient started on 100mg daily. The next 12 patients were recruited serially at a minimum of 4 week intervals and started on 200mg, 300mg or 400mg, according to a Bayesian adaptive design (Continuous Reassessment Method, CRM). Patients 14-17 were recruited as an extension cohort to better understand the safety and tolerability of the 100mg and 200mg doses. The primary endpoint was safety and tolerability at 4 weeks. Imatinib was continued for up to 24 weeks. Thirteen patients had implanted devices that provided remote daily measurements of cardiopulmonary haemodynamics and heart rate and rhythm and physical activity. Non-invasive measures of systemic blood pressure, weight and oxygen saturations were made remotely. We compared the time-haemodynamic response relationship with that produced by licensed treatments in a similar patient cohort. Results The recommended starting dose from the CRM was 200mg daily. The most common side effect was nausea. Imatinib reduced mean pulmonary artery pressure (P<0.01), increased cardiac output (P=0.08) and reduced total pulmonary resistance (TPR, P<0.001, Figure). There was a clear dose-TPR response relationship (r2=0.52, p<0.01). A reduction in TPR was evident within the first week and plateaued at 4-5 weeks. Withdrawal of Imatinib led to an increase to baseline in TPR over 4-5 weeks. This contrasts with a sharp fall in TPR with licensed therapy and rapid increase on treatment withdrawal. There was a small reduction in systemic vascular resistance (P<0.05) with Imatinib that reached plateau before TPR. Conclusions Oral Imatinib 200mg daily is well tolerated and effective as an add-on treatment in PAH. The time course of the initial haemodynamic response and the gradual return to baseline on withdrawal distinguishes Imatinib from licensed treatments and is supportive of a mechanism of action beyond reliance on vasodilation. Remote monitoring enables the safe evaluation of the withdrawal of an investigational drug in patients established on best medical therapy.Figure 1.

Angiotensin receptor-neprilysin inhibitor (Sacubitril/Valsartan) in cancer therapy-related cardiac dysfunction: real-world experience from a nurse-led cardio-oncology clinic

Abstract Introduction Cancer therapy-related cardiac dysfunction (CTRCD) is a common toxicity amongst patients receiving anti-cancer treatment1. Angiotensin receptor-neprilysin inhibitor (ARNI) Sacubitril/Valsartan is recommended to reduce Heart Failure (HF) admissions and cardiovascular mortality2. However, patients with active cancer were excluded from the key trials of ARNI. This study aims to provide a real-world experience of ARNI prescription and management from the perspective of a nurse-led Cardio-Oncology clinic. Methods This is a single centre, retrospective, observational cohort study performed at a Cardio-Oncology specialist centre between the period of 2021 to 2024. Adult cancer patients receiving anti-cancer therapy were included if they had symptomatic HF or asymptomatic CTRCD, were initiated on ARNI and followed up in the nurse-led Cardio-Oncology clinic. Results Twenty-nine patients were started on ARNI (see Figure 1). The mean age of the patients was 66+11 years and 17 (59%) were male. Cardiovascular risk factors were common: hypertension (45%), hyperlipidaemia (35%), diabetes mellitus (21%), and smoking (17%). Haematological and breast malignancies were most common (31% and 21% respectively), followed by gynaecological malignancies (14%). Twenty-one (72%) were treated with cytotoxic chemotherapy including 10 (35%) received anthracyclines. Five (17%) patients received human epidermal growth factor receptor 2 (HER2) targeted therapies, 3 (10%) were on tyrosine kinase inhibitors, and 2 (7%) received immunotherapy. Twenty-five (86%) patients presented with symptomatic HF while 4 (14%) had asymptomatic CTRCD. The median N-terminal-pro B-type natriuretic peptide (NTproBNP) level was elevated at 1325(806-4330)ng/L. Thirteen (45%) patients tolerated the maximum dose of 200mg twice daily, while 16 (56%) could only tolerate middle and lowest dosages. ARNI dose up titration to the maximum tolerated dose took 26 (15-79) days. Twenty-eight (97%) patients were on beta blockers, 26 (90%) received SGLT2 inhibitors, 25 (86%) on mineralocorticoid receptor antagonists, and 10 (35%) patients required diuretics. The most common side effect was symptomatic hypotension in 11 (38%) patients. Two (7%) had hyperkalemia, 1 (3%) acute kidney injury following initiation, and 1 (3%) had dizziness without significant hypotension. Nine (31%) required dose reduction allowing ARNI to be continued, while 3 (10%) patients had to permanently discontinue ARNI. There were no cardiovascular deaths, cancer deaths or HF admissions. Conclusion The Cardio-Oncology nurse-led clinic permits rapid up-titration of ARNI to target dosages in patients with CTRCD, resulting in significant improvements in cardiac function. The nurse lead clinic education, support and side effect management allowed uninterrupted continuation of cancer treatment. Whether this approach translates into be better cardiac and cancer outcomes requires further study.

BTKi combined with chemical immunotherapy in the initial treatment of aggressive mantle cell lymphoma: A retrospective study.

To explore the safety and efficacy of Bruton's tyrosine kinase inhibitor (BTKi) combined with immunological therapy in untreated patients with aggressive mantle cell lymphoma. A retrospective study was conducted on 9 previously untreated patients who received BTKi combined with immunological therapy, which means using immunological therapy and BTKi at the same time. The median age of the patients was 61 years, 7 were males, and the median follow-up time was 14 months. Among the 7 evaluable patients, the median follow-up was 14 months, and the objective remission rate was 100% (complete remission rate 86%, partial remission rate 14%), while the median progression-free survival and overall survival were not achieved. No patients were dead. The progression-free survival rate of 6 patients in the low-risk group was 100%. The combination of BTKi and chemoimmunotherapy has shown excellent therapeutic results in untreated patients of aggressive mantle cell lymphoma. At the same time, it also can prolong the survival time of high-risk patients. The combined therapy has acceptable safety in previously untreated patients. Hematological toxicity is the most common side effect and infection is the second one. A rash reaction was seen occasionally. There are no heart-related adverse events in the study. There are no new adverse effects caused by the combined treatment.

Use of facial cosmetics and their effects on skin among female students of Bayero University Kano, Nigeria

Cosmetics are used for cleansing, beautifying, enhancing attractiveness, or altering appearance and commonly applied by young women. This study examined the use and effects of cosmetics on the skin of female students at Bayero University Kano, Nigeria. A sample of 360 students from five faculties were randomly selected. Data on age, purpose, type, frequency of use, and effects of cosmetic products were collected. The age groups were divided into younger (18-25 years) and older (25+ years). Pearson’s Chi-square test assessed associations between age, ethnicity, and cosmetic use. The study found that facial creams (83.1%), lipstick (52.2%), eyeliners (54.7%), mascara (33.1%), eyelashes (12.5%), eyeshadow (16.1%), and foundation (15.6%) were the most commonly used cosmetics. Usage was mostly occasional (63%) or daily (37%), with 88% preferring daytime application. Significant associations were found between age and usage purpose (p=0.043), and between ethnicity and choice of cosmetics (p=0.030). Reported side effects included acne (23.3%), bleaching (25.7%), pigmentation (12.2%), rashes/itching (13.9%), irritation (5.2%), skin hardening (4.5%), and other complications (15.3%). Eye-related issues included redness (52.2%), itching (20.2%), soreness (15.4%), puffiness (3.5%), and miscellaneous problems (8.8%). Lip problems were primarily cracking (70.8%), swelling (16.9%), and bumps (12.3%). In conclusion, the use of facial cosmetics is prevalent among students, mainly for occasional use and primarily during the day. The purpose of cosmetic use varies with age and ethnicity. The most common side effects are skin pigmentation, eye redness, and swollen lips.

Impact of Long-term Fasting on Breath Volatile Sulphur Compounds, Inflammatory Markers and Saliva Microbiota Composition.

Despite substantial evidence supporting the role of resident bacterial communities in therapeutic fasting outcomes, research has primarily focused on gut microbiota, leaving changes in oral microbiota largely unexplored. The clinical significance of oral health changes during fasting is nonetheless underscored by the documented development of halitosis in fasting individuals. However, no scientific studies have comprehensively examined the interplay between salivary microbiota alterations, inflammatory changes in the gingival crevice, and the production of malodorous volatile compounds. We examined volatile sulphur compounds (VSC) in breath during fasting, cytokine levels in the gingival crevice, and oral microbiota composition of the saliva in a single-arm interventional study involving 36 subjects who fasted for 10 ± 3 days. Participants fasted according to Buchinger fasting guidelines. VSC were evaluated every morning before any food or drink intake using the OralChroma gas chromatography device. Saliva and gingival crevicular fluid (GCF) samples were collected at the clinical site before fasting, at the end of fasting, and at the end of food reintroduction. Follow-up saliva samples were sent to the patients after 1 and 3 months. Saliva samples were processed and analysed by targeted sequencing of 16S rRNA gene amplicons, whereas the expression of 6 inflammatory markers in the GCF were analysed using a multiplex fluorescent bead-based immunoassay. The quantification of volatile compounds in the breath demonstrated a statistically significant increase in dimethylsulfide levels during fasting, which corroborates the occurrence of bad breath as a common side effect of fasting. Salivary microbiota profiling showed a shift in microbial composition, including reduction in the levels of Neisseria, Gemella and Porphyromonas spp., concomitant with an increase in the levels of Megasphaera, Dialister, Prevotella, Veillonella, Bifidobacteria, Leptotrichia, Selenomonas, Alloprevotella, and Atopobium. We further demonstrated a reduction in the levels of the pro-inflammatory cytokine interleukin-8 in the GCF. Dimethylsulfide concentrations in the breath increased during fasting, and this was correlated to changes in the oral microbiota. Future studies are needed to illuminate the possible impact of these changes on oral and general health status.

DESAFIOS DO MANEJO DO LÍTIO NO PACIENTE PSIQUIÁTRICO: ESTRATÉGIAS PARA GARANTIR A SEGURANÇA E EFICÁCIA DO TRATAMENTO

Although lithium has been used for decades, its management remains a clinical challenge, since it is a drug with narrow therapeutic indices and with possible adverse effects. Therefore, this study aims to present evidence and clinical challenges of lithium management in psychiatry, in order to contribute to a better understanding of the use of this drug and the conscious management of patients who use this medication. This is a retrospective, documental Integrative Literature Review about the challenges of lithium management in psychiatric patients. For the development of this work, the following steps were followed: 1) Construction of the theme and the guiding question; 2) Establishment of inclusion and exclusion criteria; 3) Collection of studies in the scientific bases; 4) Evaluation of the selected abstracts; 5) Evaluation and categorization of studies in full; 6) Analysis and interpretation of the results. Lithium, as a mood stabilizer, was a great historical discovery and its importance lies in its effectiveness in controlling the symptoms of bipolarity, being considered a first-line mood stabilizer for the treatment of bipolar disorder and other psychopathologies. It is concluded, therefore, that the management of lithium in the treatment of psychiatric disorders requires a careful and individualized approach, taking into account the efficacy of the drug, patient safety and possible drug interactions and clinical conditions. Knowledge of the common and rare side effects of lithium is essential to ensure successful and safe treatment.

Association Between Chemotherapy-Induced Peripheral Neuropathy and Low Anterior Resection Syndrome

Introduction: Low anterior resection syndrome (LARS) can be a debilitating condition that develops after undergoing sphincter-preserving surgery for rectal cancer. Chemotherapy-induced peripheral neuropathy is a common side effect of platinum-based chemotherapy agents used as systemic therapy for rectal cancer treatment. The purpose of this study was to determine the potential relationship between CIPN and LARS. Methods: This was a retrospective review of patients who underwent a low anterior resection for rectal cancer and received systemic therapy contacted at least six months from the most recent surgery. Eligible patients were called and completed the relevant surveys over the phone or email. Results: There was a total of 42 patients who completed the surveys with 33 (79%) having major LARS. Presence of a diverting ileostomy was the only significantly differentcharacteristic in those with major LARS versus those without. CIPN was independently associated with LARS (p = 0.046) on linear regression when controlling for neoadjuvant chemoradiation, diverting ileostomy and tumor distance from the anal verge. Conclusions: Developing severe CIPN is associated with developing LARS. Further studies evaluating the etiology behind this relationship should be conducted.

Zanubrutinib, Obinutuzumab, and Venetoclax for First-Line Treatment of Mantle Cell Lymphoma with a TP53 Mutation

BackgroundTP53-mutant mantle cell lymphoma (MCL) is associated with poor survival outcomes with standard chemoimmunotherapy. Dual BTK and BCL2-inhibition with or without anti-CD20 monoclonal antibody therapy has shown promising activity in TP53-mutant MCL. We conducted a multi-center phase 2 study of zanubrutinib, obinutuzumab, and venetoclax (BOVen) in untreated MCL patients with TP53 mutation. Patients initially received zanubrutinib 160mg twice daily and obinutuzumab. Obinutuzumab 1000mg was given on cycle 1 day 1, 8, 15 and day 1 of cycles 2-8. After 2 cycles, venetoclax was added with weekly dose-ramp up to 400mg daily. After 24 cycles, if patients were in complete remission with undetectable minimal residual disease using an immunosequencing assay, treatment was discontinued. The primary endpoint was met if ≥11 patients were progression free at 2 years. The study included 25 patients with untreated MCL with TP53 mutation. The best overall response rate was 96% (24/25) and the complete response rate was 88% (22/25). Frequency of uMRD5 and uMRD6 at cycle 13 was 95% (18/19) and 84% (16/19). With median follow up of 28.2 months, the primary endpoint was met with a 2-year progression-free survival of 72%, and the 2-year disease-specific and overall survival were 91% and 76%, respectively. Common side effects were generally low grade and included diarrhea (64%), neutropenia (32%), and infusion-related reactions (24%). BOVen was well tolerated and met its primary efficacy endpoint in TP53-mutant mantle cell lymphoma. These data support its use and further evaluation of the BOVen regimen in this high-risk population. NCT03824483

Npbwr1 signaling mediates fast antidepressant action.

Chronic stress is a major risk factor for depression, a leading cause of disability and suicide. Because current antidepressants work slowly, have common side effects, and are only effective in a minority of patients, there is an unmet need to identify the underlying molecular mechanisms. Here, we identify the receptor for neuropeptides B and W, Npbwr1, as a key regulator of depressive-like symptoms. Npbwr1 is increased in the nucleus accumbens of chronically stressed mice and postmortem in patients diagnosed with depression. Using viral-mediated gene transfer, we demonstrate a causal link between Npbwr1, dendritic spine morphology, the biomarker Bdnf, and depressive-like behaviors. Importantly, microinjection of the synthetic antagonist of Npbwr1, CYM50769, rapidly ameliorates depressive-like behavioral symptoms and alters Bdnf levels. CYM50769 is selective, well tolerated, and shows effects up to 7 days after administration of a single dose. In summary, these findings advance our understanding of mood and chronic stress and warrant further investigation of CYM50769 as a potential fast-acting antidepressant.

Issue of recreational use of sildenafil

Introduction and purposeErectile dysfunction (ED) is defined as the inability to achieve and maintain an erection sufficient for satisfactory sexual intercourse. Sildenafil is one of the most popular medications used to treat ED, but in recent years, there has been a growing trend of recreational use of this drug, particularly among younger individuals, which can lead to numerous negative health consequences. The aim of this article is to provide an overview of the recreational use of sildenafil, especially among younger individuals.State of knowledgeSildenafil primarily affects the smooth muscle of the blood vessels in the corpora cavernosa, facilitating the achievement and maintenance of an erection. The most common side effects of sildenafil include headaches, dizziness, facial flushing, nausea, muscle pain, and nasal congestion. A relatively rare but potentially severe side effect of sildenafil is priapism. It is noted that those using sildenafil recreationally often have multiple sexual partners, as the drug helps them prolong sexual encounters. Studies show that sildenafil is used by groups that should have no problem achieving sexual satisfaction. The use of the drug in combination with alcohol and other substances is noticeable.ConclusionsRecreational use of sildenafil appears to be an increasingly common behavior among young men who do not have difficulties achieving or maintaining an erection. There are no studies yet that specifically examine the recreational use of sildenafil among women. It is necessary to conduct further research to better understand the prevalence of this phenomenon and to identify the factors that predispose individuals to engage in recreational use of sildenafil.

Safety and efficacy of tisotumab vedotin with cervical cancers: A systematic review and meta-analysis.

Tisotumab vedotin (TV) holds promise for treating recurrence or metastatic cervical cancer (r/mCC), with recent FDA approval for second-line use in recurrent or metastatic cases. Our research aims to evaluate TV's efficacy and safety in these patients, focusing on overall survival (OS) and progression-free survival (PFS) outcomes. We searched five electronic databases in February 2024, retrieved articles, screened them based on inclusion and exclusion criteria, and assessed their quality. A meta-analysis of the extracted data was performed and applied a random-effects model for our analysis. The search identified 86 articles, with six meeting the inclusion criteria. Meta-analysis revealed 80.8% and 48.0% OS at 6 and 12 months, and a 29.9% PFS at 6 months. Combined treatment with carboplatin or pembrolizumab showed 33.0% PFS at 1 year and 15.1% at 2 years. The objective response rate (ORR) was 21.0%, reaching 43.3% with combined treatment. Confirmed disease control rate (CDCR) was 70.0% overall and in combination. The median duration of response (DOR) was 6.1 months, increasing to 9.5 months in combined treatment, with a consistent time to response (TTR) of 1.4 months. Adverse events included ocular issues (conjunctivitis 30.3%, dry eye 18.7%) and common side effects (nausea 38.4%, epistaxis 35.7%). This systematic review and meta-analysis highlights the potential of TV as a treatment option for r/mCC patients. However, healthcare providers must communicate safety profiles and recommend prophylactic measures for optimal patient outcomes. Further studies, particularly assessing combination treatments, are needed to clarify TV's role in treatment algorithms and improve clinical outcomes.

Meloxicam-amino acids salts/ion pair complexes with advanced solubility, dissolution, and gastric safety

Amino acids have attracted attention as a potential functional excipient for optimizing biopharmaceutics characteristics of poorly soluble drugs. The amino acids are a diverse class with many functional groups, natural compounds, biocompatible and low molecular weight substances. Two amino acids serine and arginine were investigated with meloxicam. Meloxicam has extremely low solubility; being NSAIDs, gastric upset and ulcer are common side effects. Solid dispersions were produced by precipitation and physical mixing techniques. The produced combinations underwent in vitro dissolution, docking, DSC, FTIR, XRD, solubility and gastric ulcer formation studies. Docking indicated formation of ion pair/salt between the basic amino acid arginine and meloxicam. Both solubility and dissolution rates were increased by up to 3000- and 12-fold, respectively. DSC, FTIR an XRD supported these findings. Rats treated with meloxicam showed loss of surface gastric epithelium integrity and ulceration. The animal group received meloxicam: arginine showed intact gastric mucosa with the surface epithelium and gastric glands well organized and nearly similar to the untreated control. Arginine with the guanidine group that was capable of preserving gastric mucosa after repeated administration for 10 days. This study highlighted the role of arginine as a functional excipient that did not only improve solubility and dissolution rates but ameliorated the long-standing gastric side effects attributed to meloxicam.

Antifibrotic treatment response comparison of progressive pulmonary fibrosis and idiopathic pulmonary fibrosis.

Idiopathic pulmonary fibrosis (IPF) and progressive pulmonary fibrosis (PPF) are two entities categorized as fibrotic lung diseases. With a similar clinical presentation and treatment modalities in many cases, the line differentiating these two diseases may not be evident. Hence, it was aimed herein to evaluate the effectiveness of antifibrotic treatment and the course of fibrotic lung diseases. The study included patients diagnosed with IPF and PPF who were given antifibrotic treatment and followed-up for 12 months at our clinic. At the final follow-up, treatment response and radiological evaluation were investigated via high-resolution computed tomography. Eighty-seven patients were included in the study (57 with IPF and 30 with PPF). Under antifibrotic treatment, there were no statistically significant decreases in the six-minute walking test, forced vital capacity, and diffusing capacity of the lungs for carbon monoxide values at 6 and 12 months posttreatment. The most common side effects were photosensitivity for patients under the pirfenidone regimen, while diarrhea was predominantly observed in the PPF group. Radiological progression was observed in 22.9% of the patients at 12 months posttreatment. Hospitalization requirements were more evident in the PPF group, with at least one hospitalization history present in 60% (n = 18) of the PPF patients compared to 12.3% (n = 7) of the IPF patients. A personalized approach is preferred with similar clinical profiles for both treatment modalities, with specific side effects considered.
