    Traditionally, transrectal ultrasound (TRUS)-guided biopsies are done for the diagnosis of prostate cancer (PCa) in Pakistan. The transperineal template-guided saturation biopsy (TTSB) approach has been recently introduced in Pakistan and we share diagnostic yields and pathological findings of specimens taken for PCa diagnosis in men with elevated serum total prostate specific antigen (PSA) and negative TRUS-guided prostate biopsies. In all, 16 patients investigated at the Department of Urology, Sindh Institute of Urology and Transplantation (SIUT), underwent TTSB. The mean age of patients was 67.8 ± 8.8 (range: 55 - 84) years. The median PSA was 9.5 (IQR: 7.9 - 19.8) ng/ ml. The duration of symptoms before biopsy ranged from 1 month to 144 months. The prostate was enlarged with mean weight of 73.5 ± 55.5 g. Histopathology revealed PCa in 5 of 16 (31.2%) cases. The Gleason score was 6 (3+3), 7 (3+4) and 8 (4+4) in 1 case each (6.3%) and 10 (5+5) in 2 cases (12.5%). At least two cores were positive in all positive cases. None of the patients required antibiotics post-procedure. In conclusion, the TTSB technique is a promising option for patients with elevated PSA level and negative transrectal prostate biopsies for the detection of PCa in our setting.

    Background: Metabolic acidosis is the most frequent medical condition occurring in critically ill renally compromised patients. This study was aimed to determine clinical outcomes of bicarbonate therapy in renally compromised critically ill patients having metabolic acidosis.

    Methods: A prospective longitudinal cohort study was undertaken in three military hospitals in Rawalpindi, Pakistan. All patients fulfilling the inclusion criteria who were admitted to the ICU of any of the three study hospitals from July 2019 to March 2020 were studied for clinical outcomes of bicarbonate therapy using an evidence-based clinical checklist. Outcome measures include changes in blood pH, serum potassium, and sodium levels, blood pressure and weight, along with other clinically significant laboratory parameters.

    Results: Eighty-one patients fulfilling the inclusion criteria were evaluated. The mean age of the patients was 55.61±19.5 years, while the mean weight was 63.43±14.19 Kg. A mortality rate of 45.7% was observed. Disease-related complications including hypoxia, cardiac failure, multiple organ failure, elevated blood pressure, and ischemic heart disease (IHD) were found to be associated with a higher mortality rate (P<0.005). Whereas using Fisher's exact test, concomitant administration of sodium chloride, along with bicarbonate therapy was associated with a low mortality rate and had no significant impact on sodium loading or weight gain. Moreover, various drug-drug interactions were found to be associated with a higher mortality rate (P<0.05).

    Conclusion: Bicarbonate therapy was not found to affect the mortality rate in critically ill renally compromised patients with metabolic acidosis.

    Phosphorous (P) plays the prominent role to promote the plants storage functions and structural roles, as it is recognized as a vital component of ADP, ATP, Cell wall as well as a part of DNA. Soils acts as the sink to supply P to plants because soil pH and its physical condition are the main factor which regulate the solubility and availability P element. Phosphorus is not deficient in Pakistani soils but its availability to plants is the serious matter of concern. A pot experiment was conducted to evaluate P dynamics in two different soil series of Pakistan (Bahawalpur and Lyallpur) using Maize as test crop. The treatments applied were T0: Control (without any fertilizer), T1: Recommended DAP @648 mg pot-1, T2: Half dose DAP @324 mg pot-1, T3: Recommended rate of TSP @900 mg pot-1, T4: Half dose TSP @450 mg pot-1. Soil analysis showed that Bahawalpur soil has sandy clay loam texture with 33% clay and Lyallpur series has sandy loam texture with 15.5% clay; furthermore, these soil contain 4.6 and 2.12% CaCO3 respectively. Results showed an increase in P concentration in roots (23 mg kg-1) with the application of half dose of TSP in Lyallpur series and lowest in Bahawalpur series (14.6 mg kg-1) at recommended dose of DAP. Concentration of P in shoots responded the same; increase at half dose of TSP (16.7 mg kg-1) and lowest at full dose of DAP in Bahawalpur series as (15.58 mg kg-1). Adsorbed P (17 mg kg-1) was recorded highest in Bahawalpur soil with more clay amount in pot with DAP application but lower in Lyallpur soil series (14 mg kg-1) with the application of applied TSP. The PUE was recorded highest in Lyallpur series with the application of half dose of TSP and it was 61% more than control and was Highest in Bahawalpur series was with the application of recommended dose of DAP is 72% more than control treatment. On estimation; results showed that applied sources made an increase in P availability than control, but TSP gave better P uptake than DAP unless of rates applied. Soil of Lyallpur series showed better uptake of P and response to applied fertilizers than Bahawalpur series which showed more adsorption of P by high clay and CaCO3 amount. Conclusively, the study suggested that soil series play a crucial role in choosing fertilizer source for field application.

    The increasing pressures of urban development and agricultural expansion have significant implications for land use and land cover (LULC) dynamics, particularly in ecologically sensitive regions like the Murree and Kotli Sattian tehsils of the Rawalpindi district in Pakistan. This study's primary objective is to assess spatial variations within each LULC category over three decades (1992-2023) using cross-tabulation in ArcGIS to identify changes in LULC and investigates into forest fragmentation analysis using the Landscape Fragmentation Tool (LFTv2.0) to classify forest into several classes such as patch, edge, perforated, small core, medium core, and large core. Utilizing remote sensing data from Landsat 5 and Landsat 9 satellites, the research focuses on the temporal dynamics in various land classes including Coniferous Forest (CF), Evergreen Forest (EF), Arable Land (AR), Buildup Area (BU), Barren Land (BA), Water (WA), and Grassland (GL). The Support Vector Machine (SVM) classifier and ArcGIS software were employed for image processing and classification, ensuring accuracy in categorizing different land types. Our results indicate a notable reduction in forested areas, with Coniferous Forest (CF) decreasing from 363.9 km2, constituting 45.0 % of the area in 1992, to 291.5 km2 (36.0 %) in 2023, representing a total decrease of 72.4 km2. Similarly, Evergreen Forests have also seen a significant reduction, from 177.9 km2 (22.0 %) in 1992 to 99.8 km2 (12.3 %) in 2023, a decrease of 78.1 km2. The study investigates into forest fragmentation analysis using the Landscape Fragmentation Tool (LFTv2.0), revealing an increase in fragmentation and a decrease in large core forests from 20.3 % of the total area in 1992 to 7.2 % in 2023. Additionally, the patch forest area increased from 2.4 % in 1992 to 5.9 % in 2023, indicating significant fragmentation. Transition matrices and a Sankey diagram illustrate the transitions between different LULC classes, providing a comprehensive view of the dynamics of land-use changes and their implications for ecosystem services. These findings highlight the critical need for robust conservation strategies and effective land management practices. The study contributes to the understanding of LULC dynamics and forest fragmentation in the Himalayan region of Pakistan, offering insights essential for future land management and policymaking in the face of rapid environmental changes.
