Introduction: The rehabilitation of areas with localized horizontal atrophy in the molar region or with reduced interdental spaces using dental implants is challenging. In many cases, horizontal regeneration must be performed prior to implant placement, which increases the morbidity of the procedure, particularly considering it involves a unitary implant. For these situations, narrow-diameter implants with reduced platforms offer a viable solution to address localized atrophies successfully. This case series demonstrates situations resolved with these implants in a safe and predictable manner. Materials and Methods: Narrow implants with a diameter of 3.3 mm and a narrow platform (3.0 mm) were prospectively analyzed. These implants were placed in molar positions and rehabilitated as single-unit restorations in cases of localized horizontal atrophy with reduced mesiodistal spaces, avoiding the use of regenerative techniques to restore lost width. The primary variable evaluated was implant survival, followed by crestal bone loss and the occurrence of surgical or prosthetic complications during the follow-up period. Qualitative variables were described using frequency analysis, while quantitative variables were summarized using mean and standard deviation. Implant survival was estimated using the Kaplan-Meier method. Results: Thirteen patients were recruited, receiving a total of 15 implants that met the inclusion criteria. Of these, 73.3% were placed in the mandible, with position 46 being the most frequent location. All the implants studied had a diameter of 3.3 mm with a platform of 3.0 mm and were placed for unitary molar rehabilitation, using screw-retained crowns supported by single abutments. Implant lengths were 5.5 mm in 33.3% of cases and 6.5 mm in the remaining 66.7%. The mean mesial bone loss at the end of the follow-up was 0.49 mm (+/- 0.21), while the mean distal bone loss was 0.43 mm (+/- 0.28). Conclusions: Narrow-platform (3.0 mm) and reduced-diameter implants can be placed in molar regions and rehabilitated as single-unit restorations in cases of localized horizontal atrophy, reduced interproximal spaces, or both factors combined, with favorable outcomes.

Background: The COVID-19 pandemic necessitated exploration of convalescent plasma (CP) therapy. This phase-II RCT evaluated CP's efficacy in 30 severe COVID-19 patients (June 2020–July 2021), comparing standard care (n=30) with CP-added therapy (n=30). Despite historical success in viral outbreaks, evidence remained conflicting. We assessed 28-day mortality, clinical improvement, and safety, addressing gaps in donor antibody variability and timing. Objective: To determine therapeutic Role of Convalescent Plasma (CP) therapy in the treatment of severe COVID-19. Methods and Procedure: It was a Randomized Controlled phase-II Trial which was carried out at COVID-19 unit and ICU Bangabandhu Sheikh Mujib Medical University, Dhaka from 01June 2020 to 31July 2021. Plasma was collected and supplied in the department of Transfusion Medicine of BSMMU and transfused in patient at ICU, BSMMU. After proper evaluation 30 healthy donors required amount of convalescent plasma of COVID-19 was collected by continuous flow cell separator. The collected convalescent plasma was transfused to; 30 (INTERVENTION ARM) severe ill patients receiving standard treatment protocol admitted in ICU, BSMMU, Dhaka. Then the improvement of these patients was observed and another 30(control) patients receiving standard treatment protocol only and comparison was made. Before administration of the plasma it was screened for RCT-PCR for covid-19. HBsAg, Anti-HCV, HIV and other infections. Results: The study included 60 COVID-19 patients (30 control, 30 intervention) with comparable baseline characteristics (mean age 51-53 years; 40% vs. 56.6% males). The intervention group showed significantly higher baseline D-dimer (4.3 vs. 0.5 µg/mL, p<0.001) and ferritin (1045 vs. 631 ng/mL, p=0.049). Both groups had similar 28-day mortality (26.6%, RR=1.00, p=0.95), hospitalization duration (10 vs. 9 days), and discharge rates (63.3%). Clinical parameters improved over time, with mortality declining from 7.1% (Week-I) to 4.5% (Week-IV). Conclusion: In conclusion, this phase-II randomized controlled trial demonstrated that convalescent plasma (CP) therapy did not significantly improve 28-day mortality or other clinical outcomes in severe COVID-19 patients compared to standard care alone.

This study examines heavy metal contamination and bioaccumulation in earthworms across three sites in Ekiti State, Nigeria: Are Oil Palm plantation, Irasa waste dumpsites, and EKSU Teak plantation. Soil and earthworm samples were analyzed for copper (Cu), cadmium (Cd), lead (Pb), and zinc (Zn) using atomic absorption spectrophotometry. Results showed the highest contamination at Irasa waste dumpsites, with Cu, Cd, Pb, and Zn concentrations averaging 45.2 mg/kg, 8.4 mg/kg, 36.7 mg/kg, and 112.5 mg/kg, respectively. Are Oil Palm plantation exhibited moderate contamination, with Cu, Cd, Pb, and Zn averaging 29.5 mg/kg, 4.2 mg/kg, 18.6 mg/kg, and 67.9 mg/kg. The EKSU Teak plantation showed the lowest levels, averaging 15.3 mg/kg for Cu, 2.1 mg/kg for Cd, 9.8 mg/kg for Pb, and 35.4 mg/kg for Zn. Bioaccumulation analysis revealed a strong correlation with soil contamination, with earthworms from Irasa waste dumpsites containing the highest concentrations of Pb and Cd, at 25.3 mg/kg and 5.6 mg/kg, respectively. Earthworms from Are Oil Palm recorded 13.1 mg/kg for Pb and 2.9 mg/kg for Cd, while those from EKSU Teak had the lowest levels, at 6.5 mg/kg for Pb and 1.5 mg/kg for Cd. The study highlights significant heavy metal contamination and bioaccumulation gradients influenced by anthropogenic activities. The elevated contamination at Irasa waste dumpsites emphasizes the need for pollution control and remediation strategies to protect soil and ecological health.

Background: This study investigates the morphometric and morphological characteristics of the external ear in the Omuma population, a distinct ethnic group in Nigeria. The external ear’s unique anatomy and its individual variability, influenced by genetic, environmental, and cultural factors, have applications in forensic science, anthropological research, and clinical medicine. The research aims to provide baseline data specific to this population, filling a gap in the existing anthropometric literature. Materials and Method: A descriptive cross-sectional study design was employed in Omuma, Rivers State, Nigeria. Participants 250 volunteers aged 16–45 years, with both parents and grandparents from the Omuma ethnic group. Sampling Method: Random sampling, with sample size determined using the Taro Yamane formula. Materials and Techniques: smart camera, 2 cm graph paper, Vernier calipers, and statistical software for analysis. Morphometric data included parameters such as ear length, width, and lobule dimensions. Morphological observations documented variations in ear shape and structure. Results and Discussions: The findings reveal significant morphometric and morphological variations in the external ear among the Omuma population. Sexual Dimorphism: Male participants exhibited larger ear dimensions compared to females. Variations aligned with genetic and environmental influences unique to the Omuma group. The study corroborates earlier findings on the relevance of ear dimensions in forensic identification, reconstructive surgery, and anthropological research. The significance levels observed for ear length, width, and lobule height (p < 0.05) validate the importance of these parameters in distinguishing sex and ethnicity. Conversely, the non-significance of lobule width (p > 0.05) indicates that this measure may not be a reliable indicator of sexual dimorphism in this population. Conclusion: This research provides essential baseline data for the Omuma population, highlighting the clinical, forensic, and anthropological importance of understanding population-specific ear morphology. The results of this study revealed that free earlobes occurred more frequently than attached earlobes and earlobe attachment did not demonstrate any significant correlations with either gender or age group. Also, males had slightly higher lobule lengths and widths than females, but these differences were not statistically significant.

The purpose of this study is to improve general endurance of students, by selecting and implementing appropriate exercises. All participants were the freshman majoring in physical education in Vinh University, Vietnam. Participants were randomly assigned to either a experiment group (MG) or a Control Group (CG). Fifty students were randomly assigned to an experimental (n=25) or control group (n=25) for a sixteen-week study. Both groups had regular physical education twice weekly. The experimental group received extra athletic training twice weekly, while the control group followed the standard curriculum. Physical fitness tests, including 5-minute running, 800m running, and 1-minute rope jumping, were used as outcome measures. After sixteen weeks, the experimental group showed significantly improved performance in all tests (p < 0.05) compared to the control group, demonstrating the effectiveness of the exercise program in enhancing student endurance.

Background: Hyaline fibromatos is syndrome (HF) is a rare condition characterized by hyaline deposits in the papillary dermis that lead to joint contractures, motor impairment, thickened skin, and hyperpigmented macules. Severe cases may present with protein-losing enteropathy (PLE), increasing the risk of mortality. The diagnosis of HFS involves clinical evaluation, genetic analysis of ANTXR2 variants, skin and intestinal biopsies, skeletal x-rays, and molecular genetic testing. Treatment focusses on the management of symptoms and includes various interventions such as splinting, excision of lesions, hydration, and pharmacotherapy. Case presentation: We present the case of a 2-month-old female child with HFS, born prematurely to consanguineous parents. The child exhibited characteristic symptoms, including excessive crying, limb deformities, and congenital hypothyroidism. Despite symptomatic management and prenatal diagnosis counseling, the child succumbed to sepsis after a month. Conclusions : HFS presents significant challenges in clinical management, particularly in severe cases where complications such as protein-losing enteropathy can lead to fatal outcomes. Early diagnosis through comprehensive genetic and clinical evaluation is crucial for appropriate management and counseling of affected individuals and their families.

The increasing intensification of the exploitation of fishery resources in Africa in general and in Côte d'Ivoire in particular, associated with the processes of degradation of the natural environment, pose real risks of regression, disappearance of species and reduction of fish production. So, knowledge of fishing parameters is very important in the strategy implemented by managers of this sector on Ivorian rivers and bodies of water. Thus, the composition of catches, fishing effort and fishing gear production were studied in the Bandama River from July 2023 to June 2024. The data was collected by experimental fishing with gillnets and traps to which fishing data were added artisanal fishing carried out during the sampling days. A total of 41 species belonging to 5 orders and 13 families of fish with a biomass of 18896 kg were identified. Siluriformes (44%) and Perciformes (26%) were dominant. The highest fishing efforts and CPUEs were obtained with gillnets and papolo traps. The values were maximum in the rainy season. Annual production was 7285.74 Kg for the gillnets and 5066.53 Kg for the papolo traps. The results of this study revealed that fish from the Bandama River at Lamto are overexploited. This constitutes a basic element for decision-making in the quest for a protection and conservation strategy of the fishing resources of this protected area in Côte d’Ivoire.

Background: Laparoscopic cholecystectomy (LC) is the standard treatment for gallbladder diseases, traditionally performed under general anesthesia (GA). However, spinal-epidural anesthesia (SEA) has emerged as a potential alternative due to its advantages in postoperative recovery, reduced nausea, and improved pain control. Despite these benefits, the choice between SEA and GA remains debated in clinical practice. Objective: This study aims to compare the perioperative and postoperative outcomes of LC performed under SEA versus GA, focusing on pain management, complications, and recovery parameters. Methods: A prospective randomized controlled trial was conducted at a tertiary care hospital from September 2023. A total of 97 patients were randomly allocated to undergo LC under SEA [n=48]or GA[ n=49]. Inclusion criteria included ASA I-II status, age 18-65 years, and BMI ≤30 kg/m². Perioperative parameters, postoperative pain (Visual Analog Scale), complications, and hospital stay duration were assessed. Statistical significance was determined using appropriate tests, with an interim analysis performed after the first 100 patients. Results: Baseline characteristics were comparable between groups. Median operative time was 45 minutes for SEA and 47 minutes for GA. SEA patients experienced significantly lower postoperative pain scores at all time points (p < .001). The incidence of postoperative nausea and vomiting was slightly higher in the GA group (16.7%) than in the SEA group (14.3%). Urinary retention was observed only in the SEA group (6.1%), while dizziness and sinus tachycardia were exclusive to GA (2.1% each). The median hospital stay was one day for both groups. Conclusion: SEA provides superior postoperative pain control compared to GA while maintaining comparable operative and anesthesia durations. Although SEA was associated with urinary retention, GA had a higher incidence of nausea, dizziness, and tachycardia. These findings support SEA as a viable alternative to GA in LC, particularly for patients prioritizing pain reduction and enhanced recovery.

Background: Dyslipidemia, characterized by abnormal lipid profiles, is a significant risk factor for cardiovascular disease and has been increasingly implicated in the progression of chronic kidney disease (CKD). Dyslipidemia contributes to endothelial dysfunction, oxidative stress, and inflammation, potentially exacerbating renal impairment. However, the association between dyslipidemia and key renal risk factors—estimated glomerular filtration rate (eGFR), proteinuria, anemia, and C-reactive protein (CRP)—in renal transplant recipients remains inadequately explored. Objective: To assess the association between dyslipidemia and renal risk factors, including eGFR, proteinuria, anemia, and CRP, in renal transplant recipients. Methodology: A cross-sectional observational study was conducted at Sir Salimullah Medical College & Mitford Hospital, the CKD and Urology Hospital (CKD&U), and the Kidney Foundation Hospital and Research Institute, Bangladesh, over 13 months (May 2019–June 2020). A total of 105 renal transplant recipients were included through purposive sampling. Demographic, clinical, and laboratory data were collected, including fasting lipid profiles, serum creatinine, fasting blood glucose, urinary albumin-to-creatinine ratio (ACR), CRP, and eGFR (calculated using the MDRD equation). Statistical analysis was performed using SPSS v16, applying Chi-square tests to evaluate associations between dyslipidemia and renal risk factors. Results: Among renal transplant recipients, 61.9% had elevated triglycerides, 53.3% had high LDL, 33.3% had elevated total cholesterol, and 61.0% had low HDL. The mean triglyceride level was 214.38 ± 128.33 mg/dL, and the mean LDL was 100.41 ± 36.31 mg/dL. Dyslipidemia was significantly associated with reduced eGFR (p=0.04), indicating a decline in renal graft function. Lower ApoA1 levels were significantly linked to elevated CRP (p=0.01) and reduced eGFR (p=0.043), while higher ApoB levels were also associated with reduced eGFR (p=0.038). Hypertriglyceridemia was significantly correlated with anemia (p=0.05). However, no significant associations were observed between lipid markers and proteinuria, hypertension, or diabetes. Conclusion: Dyslipidemia, particularly elevated triglycerides and low HDL levels, is significantly associated with reduced renal function and systemic inflammation in renal transplant recipients. Specific lipid markers, such as ApoA1 and ApoB, may play a critical role in predicting renal dysfunction and inflammatory status. Early detection and management of dyslipidemia may be crucial in preserving renal function and improving long-term transplant outcomes.
