Methods This study utilised 2024 data from EUDAMED (European Database on Medical Devices), BfArM (Bundesinstitut für Arzneimittel und Medizinprodukte), and MAUDE (Manufacturer and User Facility Device Experience (FDA database)) to identify recurring incidents, associated device types, and the outcomes of FSCAs. A quantitative analysis was conducted to evaluate the frequency and severity of reported incidents, focusing on hardware failures, software malfunctions, and calibration issues. The impact of recalls, software updates, and field modifications on incident recurrence was also assessed. Results Orthopaedic implants, infusion pumps, and cardiac monitoring devices reported the highest number of incidents, primarily due to hardware failures and software issues. FSCAs involving hardware modifications significantly reduced recurrence rates, particularly for high-risk devices like pacemakers and ventilators. In contrast, software-driven devices exhibited persistent issues despite corrective actions, highlighting challenges in maintaining long-term reliability. Interpretation & conclusions The findings underscore the importance of robust PMS systems and tailored corrective actions in mitigating risks associated with high-risk medical devices. While FSCAs have demonstrated effectiveness in addressing hardware-related failures, enhancements in regulatory frameworks are necessary to improve the management of software-driven devices.</p>","PeriodicalId":13349,"journal":{"name":"Indian Journal of Medical Research","volume":"162 2","pages":"163-168"},"PeriodicalIF":2.5,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145307987","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Present study is aimed to understand the natural history and quality-of-life (QoL) in the two well studied IPFDs i.e. Glanzmann thrombasthenia (GT) and Bernard Soulier syndrome (BSS). Methods This is an ambispective, observational study. Demographics, medical data, mortality due to bleeding, comorbidities and treatment products were recorded. Health related quality of life (HRQoL) was captured using EuroQol five-dimensional questionnaire (EQ-5D), 36-Item short form health survey (SF-36) and functional assessment of chronic illness therapy (FACIT) scales. The severity of bleeding was assessed by annual bleed rate (ABR) and International Society on Thrombosis and Haemostasis - Bleeding assessment tool (ISTH-BAT) score. Results The median (interquartile range; IQR) age of 76 study participants (64 GT, 12 BSS) was 14 yr (9-19 yr). Epistaxis, ecchymosis, gingival bleed, gastrointestinal bleed, and soft tissue bleed were the commonest clinical manifestations. Menorrhagia was seen in all females in the reproductive age group. There was a statistically significant difference in the mean ISTH-BAT scores between GT and BSS (P=0.016). Platelet transfusion was the main mode of treatment; none of the patients in the present series were on activated recombinant factor VII (rFVIIa) therapy. Between 2000 and 2025, 13 deaths were reported (due to bleeding) mainly due to inaccessibility to treatment or treatment products. The relationship between quality of life (QoL) scores and ISTH-BAT score was weak.

Methods A total of 25,408 individuals (with/without HTN and T2D), a nationally representative sample, were included from the Indian Council of Medical Research-INdia-DIABetes (ICMR-INDIAB) cross-sectional study. IKF was defined as estimated glomerular filtration rate eGFR <60 mL/min/1.73 m2 (CKD-EPI-2009 equation-race free). Results The overall weighted prevalence of IKF was 3.2 per cent [95% confidence interval (CI): 2.9-3.5] with no significant differences between urban [3.3% (2.8-3.7)] and rural areas [3.2% (2.9-3.5)], but higher among males [3.8% (3.4-4.2)] compared to females [2.6% (2.3-2.9)].

However, each year more than one-third of all global TB cases remain undetected and unreported. On top of that, emergence of drug-resistant TB poses a major challenge. Therefore, a Reliable, Accessible, Cost-Effective, and Easy (RACE) diagnostic modality is crucial for starting suitable treatment of TB and curtailing its transmission. In the last two decades, several advances have been made for improved diagnosis, which include liquid culture and drug susceptibility testing (DST), line probe assay (LPA) for drug resistance detection at the molecular level, and cartridge-based nucleic acid amplification tests (CBNAAT) for rapid diagnosis of TB and rifampicin resistance detection. Newer drugs and treatment regimens have been introduced and vaccines are in the pipeline. Despite these advances and opportunities, a precise, affordable, and accessible diagnostic model is yet to be evolved, especially in rural and difficult-to-reach areas, where the most desirable test would be a test that is easy to perform, accessible to masses, is cost-effective, besides being reliable. Only a point-of-care triage test can meet these requirements, which can be used by an unskilled or minimally trained healthcare worker or even by the patient (self-testing).

In 1952, a pathology professor discovered an endemic focus of S. haematobium in a small village named Gimavi in Ratnagiri district, Maharashtra. Its emergence about 5,000 km away from its homeland in Africa, the absence of the known vector, Bullinus, in India, and its confinement to only one village were enigmatic. The Government of Maharashtra executed several activities and eliminated the focus after about 40 years. Many practicing and teaching public health experts today are unaware of the focus and the efforts undertaken for its elimination. This study's objectives were to identify clinical features, enlist the containment activities undertaken by the government, and identify reasons for confinement. Methods We conducted a qualitative study using in-depth interviews. All available past patients, two health personnel (male and female health workers), a medical officer, a district health officer, the concerned senior officer from the Directorate of Health Services, a scientist from Haffkine Institute, Gramsevak/Talathi (village level healthcare workers), Sarpanch/Up-sarpanch (administrative heads of a large village or a cluster of small villages), at least one from each category, were interviewed. The study included persons who worked during that period. Results The investigator interviewed ten personnel and two past patients. Many children had painless and mild haematuria, which persisted for some years. All respondents knew about the tiny snails living in the rivulet transmitted the disease. Construction of bridges, tanks, toilets, water supply schemes, barbed fencing along banks, manual collection/destruction of snails, health education, and mass drug administration eliminated the focus. Besides Gimavi, the rivulet flows through two villages and joins an estuary of a river where, due to high salinity, tiny freshwater snails cannot survive. Interpretation & conclusions A new species of snail was discovered to transmit S. haematobium. The disease was mild and self-limiting. A multipronged attack eliminated the focus.
