Sex-specific differences in risk factors, comorbidities, diagnostic challenges, optimal management, and prognostic outcomes of heart failure with preserved ejection fraction: A comprehensive literature review.

Due to hormonal variations, heart failure with preserved ejection fraction (HFpEF) remains prevalent in women and affects almost half of the heart failure (HF) patients. Given the yearly death rate of 10-30% and the unavailability of medications targeting HFpEF, the need arises for a better understanding of the fundamental mechanisms of this syndrome. This comprehensive review explores sex-specific differences in traditional risk factors; female-specific factors that may impact HFpEF development and response to therapy, including variations in hormone levels that may occur pre- and post-menopausal or during pregnancy; and disparities in comorbidities, clinical presentation, and diagnostic challenges. Lastly, the review addresses prognostic outcomes, noting that women with HFpEF have a poor quality of life but a higher survival rate. It also discusses novel biomarkers and precision medicine, emphasizing their potential to improve early detection and personalized treatment.

Clinical Presentation, Tumor Characteristics, and Management of Intradiverticular Transitional Cell Carcinoma of the Urinary Bladder: A Systematic Review.

Intradiverticular transitional cell carcinoma (TCC) of the bladder poses unique challenges due to its presentation within the bladder diverticula. This review synthesizes current knowledge on the diagnosis and management of this condition, emphasizing the need for early detection to optimize patient outcomes. The literature underscores the importance of tailored treatment strategies, ranging from radical surgeries to adjuvant chemotherapy, to combat the aggressive nature of intradiverticular TCC. Additionally, stringent post-treatment surveillance protocols are vital in addressing high recurrence rates. Future research directions include biomarker identification, comparative efficacy studies of treatment modalities, and the exploration of innovative therapeutic approaches such as immunotherapy. Longitudinal studies analyzing patient outcomes will provide valuable insights into survival rates and quality of life post-treatment, informing future clinical guidelines. This comprehensive review aims to enhance understanding and management strategies for intradiverticular TCC, paving the way for improved patient care and outcomes in this challenging form of bladder cancer.

Evaluation of non-invasive diagnostic tools for diarrhea: a systematic review of point-of-care tests and biomarkers.

Background: Diarrhea is a prevalent condition affecting millions worldwide. However, current standard diagnostic methods have many drawbacks. This review examines various non-invasive point-of-care (POC) tests and biomarkers aiding rapid diagnosis of diarrhea from different causes. Methods: PubMed, PubMed Central, ScienceDirect, Cochrane Library, and Google Scholar were searched from 2013 to present for relevant literature. Two reviewers independently assessed included studies' quality using the Critical Appraisal Skills Programme (CASP) checklist. Results: The search yielded 1453 studies, of which 39 were included after screening and applying eligibility criteria. Polymerase chain reaction (PCR) was the POC test in 25 studies, providing consistent sensitivity and specificity. For biomarkers, C-reactive protein (CRP), fecal calprotectin, and procalcitonin offered high sensitivity and specificity for conditions like acute pediatric diarrhea, microscopic colitis, and inflammatory diarrhea, respectively. Conclusion: PCR proved the ideal POC test for rapid diarrhea diagnosis, while the procalcitonin biomarker helps differentiate inflammatory from non-inflammatory diarrhea. Other reviewed tools also demonstrated promising diagnostic performance, though improvements in sensitivity, specificity, and usability are still needed.
