Breast cancer is one of the most common cancers in females. In low- and middle-income countries like Pakistan, reported incidence and prevalence remain unreliable. The aim was to evaluate Pakistani women’s knowledge, attitude, and perception of breast cancer. This cross-sectional study was conducted among Pakistani women from Punjab, Pakistan. A self-administered online questionnaire was formulated to collect data from the participants from September 24, 2022, to October 24, 2022. The questionnaire included sociodemographic data, knowledge questions regarding breast cancer risk factors, knowledge questions about symptoms of breast cancer, and questions assessing the participants’ attitudes toward mammography screening. For knowledge questions, a score of more than 7 out of 13 was considered good knowledge. For attitude questions, regression analysis was done and a score of more than 5 out of 11 was considered a positive attitude. Data was analyzed using SPSS version 25 (Chicago). 796 women participated in this study. Out of 796 participants, 543 (68.2%) were between 20 and 30 years of age, and 43 (5.4%) were more than 40 years old. The level of knowledge regarding breast cancer risk factors was suboptimal. 523 (65.7%) of the participants thought that breast cancer risk increases with advancing age and 218 (27.4%) thought that early menarche increases the risk of developing breast cancer. 471 (59.2%) mentioned that mammography is an effective tool for detecting breast cancer, and 30 (3.8%) thought that there is a cure for breast cancer. According to regression analysis, higher education, higher monthly household income, and married marital status were significantly associated with good knowledge related to breast cancer. Although most of the population is aware of breast cancer’s risk factors and symptoms, they avoid screening such as mammography. Public awareness projects could help increase women’s knowledge of breast cancer signs, symptoms, and screening.

Abstract Introduction: Tuberculosis (TB), a substantial cause of morbidity and mortality among human immunodeficiency virus (HIV) infected individuals, accounted for 161,000 deaths among HIV-co-infected patients in 2023. Tuberculosis preventive therapy can play a detrimental role in reducing the global burden. However, prolonged treatment duration compromises adherence and ultimately efficacy. This systematic review and meta-analysis aimed to assess the treatment adherence and effectiveness of rifapentine-isoniazid prevention therapy relative to the standard isoniazid therapy. Methods: This study was conducted following the PRISMA guidelines. A comprehensive literature search was conducted over PubMed/Medline, Google Scholar, Cochrane Library, and ClinicalTrials.gov from inception till 28 October 2024. Recruited articles were screened against the predefined inclusion criteria, and relevant data was extracted into a spreadsheet. Comprehensive Meta-Analysis (CMA) was used for data synthesis. Results: This meta-analysis included four studies containing data from 8,068 patients, with 5640 randomized to the rifapentine-isoniazid group while 2428 received isoniazid. Tuberculosis incidence varied from 0.21 to 2.0 and 0.63 to 1.9 per 100 person-years in the rifapentine-isoniazid arm and isoniazid alone group respectively. However, the pooled analysis showed a non-significant difference between the two groups (OR: 1.12; CI: 0.65 to 1.93; p=0.69) as shown in Figure 1. Similarly, no significant difference was noted across deaths in each group (OR: 0.76; CI: 0.43 to 1.34; p=0.35). While the two preventive therapies were non-inferior in terms of effectiveness, a significant improvement in treatment completion was observed with the rifapentine-isoniazid group (OR: 5.14; CI: 2.96 to 8.96; p<0.0001). Conclusion: The short-term rifapentine-isoniazid preventive therapy was non-inferior to the standard isoniazid therapy, however, a marked improvement in treatment completion was noted with the former.

Abstract Introduction:AFOP is a pattern of lung injury with intra-alveolar fibrin balls and organizing pneumonia. In 2013, the ATS/ERS revised their classification of idiopathic-interstitial-pneumonia to include acute-fibrinous-organizing-pneumonia(AFOP) in their rare histologic patterns. Methods: MEDLINE(PubMed), EMBASE, and Cochrane were searched for AFOP-related case reports/case series. Mesh terms used included (“acute fibrinous and organizing pneumonia” OR AFOP OR “acute fibrinous organizing pneumonia” OR (“acute fibrinous” AND “organizing pneumonia”) OR (“acute fibrinous” AND “organizing pneumonia”). A total of 177 patients were synthesized in these 169 articles, 9 of which were case series and the rest individual case reports. A quality review and data extraction was done on Covidence using a JBI checklist.Results:Mean age of 52.2 +/- 17.4 years with 55% of them were males. The associations were; malignancy (16%), smoking (14%), organ transplant (13%), Hypertension (10%), and use of immunosuppressive agents (6%) were frequent risk factors. Cough (73%), shortness of breath (71%), and fever (61%) were found highly frequent symptoms. Predominant radiological findings were multifocal infiltrates/consolidation (50%) and ground glass appearance (39%). Leukocytosis and inflammatory markers were elevated in most cases. Transbronchial/EBUS (32%), open surgical (29%), imaging-guided (22%), and VATS (14%) were common modes of lung biopsy. Treatment is usually steroids (88%) and antibiotics (69%). Death occurred in 23% of the cases, clinical or radiological improvement was achieved in 69%, while only three recurrences were reported. Most cases are either idiopathic or associated with myelodysplastic syndrome as causative factors reported by authors. DiscussionAFOP presents non-specific symptoms and a community-acquired pneumonia-like clinical picture. Treatment included antibiotics, corticosteroids, and other immunosuppressants with variable outcomes. Discontinuation of suspected drug was the sole treatment strategy reported in some cases. Partial lobectomy/lesion resection was a successful treatment in some instances with localized disease.The survival in AFOP was significantly worse than obliterative bronchiolitis (median time to death 101 vs. 294 days; P = 0.02). A statistically non-significant trend towards higher mortality associated with higher body mass index (BMI) and a long interval between symptom onset and diagnosis of AFOP was reported by Kim et al. in a cohort from South Korea. Conclusion:AFOP being a rare histological pattern of acute lung injury, is a relatively new entity that requires a better clinical and radiologic understanding for the clinical challenge it poses. This systematic review will be able to provide answers to clinicians to think in that direction and manage acute lung injury accordingly.

Purpose: To systematically review the literature on the effectiveness, safety, and long-term outcomes of genicular artery embolization (GAE) for knee joint osteoarthritis (OA) associated pain. Materials and Methods: After registering the protocol with the PROSPERO database, a search was conducted from inception until July 31, 2023, in MEDLINE, Cochrane Central Register of Controlled Trials, and ScienceDirect databases to gather studies evaluating GAE’s safety and efficacy in knee OA. A total of 4979 studies were identified and evaluated against the inclusion criteria. Data on study characteristics, success parameters, and adverse events were collected and synthesized. Results: Twenty-three studies, primarily single-center prospective studies with a total of 657 patients, were included. Most studies reported a 100% technical success rates, except one study reporting a rate of 84.2%. Clinical success rates, defined variably across studies, ranged from 30% to 100%, depending on the study’s follow-up period and outcome measures. The most frequent adverse events included skin discoloration without an ulcer (15.6%, n = 98) and transient post-procedural knee pain (10.2%, n = 64). Most studies were rated as fair in terms of quality, but the lack of robust randomized controlled trials highlighted the need for further comparative studies to standardize outcome reporting. Conclusion: GAE appears to be a promising option for knee OA pain, particularly for patients unresponsive to conservative treatments or ineligible for surgery. High-quality studies are needed to confirm long-term effectiveness and standardize outcome measures. Clinical Impact This study highlights the safety and efficacy of genicular artery embolization as a minimally invasive treatment for knee osteoarthritis, particularly in patients who are unresponsive to conservative treatments or unsuitable for surgery. By targeting neovascularization and reducing inflammation, genicular artery embolization provides pain relief and functional improvement. Clinicians can consider genicular artery embolization as an alternative to surgery for mild-to-moderate OA, offering a lower adverse event rate and faster recovery.

Background: Soluble urokinase plasminogen activator receptor (suPAR) is an inflammatory biomarker that is used to predict mortality, readmission, early discharge, and LOS, thus, serves as a useful tool for ED physicians. Our study aims to analyze the efficacy of suPAR in predicting these prognostic markers in ED. Methods: We performed a comprehensive search on 6 databases from the inception to 30th November 2022, to select the following eligibility criteria; a) observation or triage trial studies investigating the role of suPAR levels in predicting: 30 day and 90-day mortality, 30-day readmission, early discharge (within 24hr), and LOS in patients coming to AMU. Results: A total of 13 studies were included, with a population size of 35,178, of which 52.9% were female with a mean age of 62.93 years. Increased risk of 30-day mortality (RR = 10.52; 95% CI = 4.82–22.95; I2 = 38%; P < .00001), and risk of 90-day mortality (RR = 5.76; 95% CI = 3.35–9.91; I2 = 36%; P < .00001) was observed in high suPAR patients. However, a slightly increased risk was observed for 30-day readmission (RR = 1.50; 95% CI = 1.16–1.94; I2 = 54%; P = .002). More people were discharged within 24hr in the low suPAR level group compared to high suPAR group (RR = 0.46; 95% CI = 0.40–0.53; I2 = 41%; P < .00001). LOS was thrice as long in high suPAR level patients than in patients with low suPAR (WMD = 3.20; 95% CI = 1.84–4.56; I2 = 99%; P < .00001). Conclusion: suPAR is proven to be a significant marker in predicting 30-day and 90-day mortality in ED patients.
