Background:Habitat degradation is known to have a major impact on the composition of bird communities,yet how these communities recover following such disturbance is less *** study examined bird community changes from pre-logging to recovery over the course of habitat disturbance caused by the development of the Hulu Terengganu Hydroelectric Dam Project in Peninsular Malaysia,between 2007 and *** surveys were conducted using point count observations and mist netting in the dam area from the prelogging phase until the operation ***:It was observed that while bird species significantly declined after large-scale habitat clearance between the pre-logging and construction phases,they showed positive signs of recovery from the inundation to operation *** findings indicate that the bird community is still recovering,and the permanent loss of habitat required by most of the original species has not occurred,as evidenced by *** species composition differed across phases due to varying habitat *** turnover rate and immigration rate(recolonisation and newly recorded species)were higher between the construction and operation *** was also observed that insectivorous birds were more heavily affected than others by changes to the landscape,which highlights the versatility,survivability and tolerance of certain species to extreme disturbance and habitat ***:Although the operation phase showed an incremental change in bird species richness due to recolonisation and newly recorded species,this value remains far from that of the pre-logging *** predict that bird species recovery will continue to increase for some time before reaching a plateau among the newly created islands,reservoir and catchment area of the dam.

Background: Bronchiectasis, characterized by irreversible bronchial dilation, often affects patients’ long-term health. This study assessed the prevalence and risk factors of bronchiectasis in adults based on CT scan-finding department (OPD) patients in a single center. Methods: We retrospectively reviewed the medical records of 301 adult OPD patients examined between 2021 and 2022. We diagnosed bronchiectasis based on high-resolution chest CT scans. We analyzed demographic characteristics, tuberculosis (TB) history, and the presence of comorbid conditions using electronic medical records. We conducted univariate and multivariate analyses to identify potential risk factors for bronchiectasis. Results: Among 301 patients who had high-resolution chest CT scans, 139 (46.1%) received a diagnosis of bronchiectasis. Multivariable analysis revealed significant associations between bronchiectasis and the following factors: age greater than 50 years and history of tuberculosis. We found no significant correlation between gender and smoking history. Conclusion: This study found a high prevalence of bronchiectasis (46.1%) among OPD patients in our single center, with older age and a history of tuberculosis identified as independent risk factors.

Background: In Africa, female genital mutilation (FGM) is a widespread and harmful practice, with Somalia having the highest incidence at 98%. This practice has severe and long-lasting physical and mental health consequences. The aim of the study was to evaluate the different types of FGM;immediate and long-term complications associated with the practice, and identify factors related to its prevalence. Method: In a one-year cross-sectional hospital-based study, data were collected from females aged 18 - 50 with a history of FGM. Face-to-face semi-structured questionnaires were used for data collection. Data analysis was performed using SPSS version 26, utilizing univariate and bivariate analyses to identify correlations between variables, which were presented in tables. Results: In a study involving 255 female participants, 65.5% were between 18 and 30 years old. The majority (82.7%) were married, while 47.1% were illiterate. FGM cases were more prevalent in rural areas (61.6%). Among the participants, 45.1% were employed. Type 3 FGM was the most common (44.3%), followed by Type 2 (32.2%) and Type 1 (23.9%). In terms of short-term complications experienced by circumcised women, the most common were bleeding, reported by 29.8% of participants, followed by infection (25.1%), and urinary retention (19.2%). Among the long-term complications observed, recurrent vaginal infections were the most prevalent, affecting 29.8% of the surveyed females. This was episiotomy during delivery (22.3%) and genital scarring (10.2%). Conclusion: The study reveals that Type 3 FGM is highly prevalent among the surveyed females, contributing to an increased risk of recurrent vaginal infections, prolonged second stage of labor, higher likelihood of episiotomy during delivery, and genital scarring. These findings emphasize the urgent need for effective preventive strategies and implementation from both international and local organizations to eliminate the harmful practice of FGM.
