Study’s Excerpt • The seroprevalence of Hepatitis B Virus (HBV) among university students was investigated. • Both serological markers of HBV and immune response were assessed. • The results revealed significant associations between infection and high-risk behaviors. Full Abstract Hepatitis B Virus is of major public health interest as it accounts for significant mortality globally. The study aimed to determine the seroprevalence of HBV infection, the possible potential risk factors, and the immunological response among students of Usmanu Danfodiyo University, Sokoto, from December 2022 to April 2023. Structured questionnaires were used to collect sociodemographic information as well as possible risk factors related to the infection. Out of 139 study participants (10 females and 129 males screened randomly for HBsAg using a rapid HBsAg test kit, 17 (12.2%) were seropositive, and 122 (87.8%) were seronegative. The sera of the positive participants were further screened for HBeAg, anti-(HBs, HBe, and HBc) using one-step cassette diagnostic kits. Of the 17 positive samples screened, none were reactive for anti-HBs antibodies and HBeAg.; while 15 were positive anti-HBc and anti-HBe, indicating a response to natural infection. Sexual activity, unprotected sexual practices, use of already used sharp objects, and awareness of HBV infection were significantly associated (P

Introduction Radiotherapy improves local tumour control in patients with soft tissue sarcoma of the extremities (STSE) but it also increases the probability of long-term toxicities such as tissue fibrosis, joint stiffness and lymphoedema. The use of radiation dose and volume thresholds, called dose constraints, may potentially reduce the development of toxicities in STSE. The aim of this study is to determine predictors of radiotherapy-related side effects for STSE.Methods and analysis Predicting radiotherapy response, Toxicities and quality-of-life related functional outcomes in soft tissue sarcoma of the extremities (PredicT) is a multicentre observational study comprising two cohorts (PredicT A and B). PredicT A, a retrospective analysis of the UK VorteX (NCT00423618) and IMRiS clinical trials (NCT02520128), is aimed at deriving a statistical model for development of dose–volume constraints. This model will use receiving operator characteristics and multivariate analysis to predict radiotherapy side effects and patient-reported outcomes. PredicT B, a prospective cohort study of 150 patients with STSE, is aimed at testing the validity of those dose–volume constraints. PredicT B is open and planned to complete recruitment by September 2024.Ethics and dissemination PredicT B has received ethical approval from North West - Liverpool Central Research Ethics Committee (20/NW/0267). Participants gave informed consent to participate in the study before taking part. We will disseminate our findings via publications, presentations, national and international conference meetings and engage with local charities.Trial registration number NCT05978024.

One of the biological components that play a vital role in the ecological integrity of an aquatic ecosystem is zooplankton. These organisms are good indicators of stressors, especially anthropogenic stressors in their environment. Thus, there is a need to study the diversity in a diversified freshwater lake (Dangana Lake) in order to provide baseline information and knowledge on the status of the lake for proper and adequate water preservation and conservation. In addition to the zooplankton structure determination, the study also examined the physicochemical parameters of the Lake. Three sampling sites were identified with distinct characteristics where water and zooplankton samples were collected for physicochemical analyses and biotic identification using standard protocols. Sampling was conducted for a duration of eight months. The monitored physicochemical parameters, i.e., temperature, dissolved oxygen (DO), biochemical oxygen demand (BOD5) and pH revealed no significant difference (p>0.05) among sampling sites. However, significance (p

Abstract Background To understand our performance with respect to the collection and reporting of patient-reported outcome (PRO) measure (PROM) data, we examined the protocol content, data completeness and publication of PROs from interventional trials conducted at the Royal Marsden NHS Foundation Trust (RM) and explored factors associated with data missingness and PRO publication. Design From local records, we identified closed, intervention trials sponsored by RM that opened after 1995 and collected PROMs as primary, secondary or exploratory outcomes. Protocol data were extracted by two researchers and scored against the SPIRIT-PRO (PRO protocol content checklist; score 0–100, higher scores indicate better completeness). For studies with locally held datasets, the information team summarized for each study, PRO completion defined as the number of expected (as per protocol) PRO measurements versus the number of actual (i.e. completed) PRO measurements captured in the study data set. Relevant publications were identified by searching three online databases and chief investigator request. Data were extracted and each publication scored against the CONSORT-PRO (PRO manuscript content checklist; scored as SPIRIT-PRO above). Descriptive statistics are presented with exploratory comparisons of point estimates and 95% confidence intervals. Results Twenty-six of 65 studies were included in the review. Nineteen studies had accessible datasets and 18 studies published at least one article. Fourteen studies published PRO results. Most studies had a clinical (rather than PRO) primary outcome (16/26). Across all studies, responses in respect of 35 of 69 PROMs were published. Trial protocols scored on average 46.7 (range 7.1–92.9) on the SPIRIT-PRO. Among studies with accessible data, half (10/19) had less than 25% missing measurements. Publications scored on average 80.9 (range 36–100%) on the CONSORT-PRO. Studies that published PRO results had somewhat fewer missing measurements (19% [7–32%] vs 60% [− 26 to 146%]). For individual PROMs within studies, missing measurements were lower for those that were published (17% [10–24%] vs 41% [18–63%]). Studies with higher SPIRIT-PRO scores and PROs as primary endpoints (13% [4–22%] vs 39% [10–58%]) had fewer missing measurements. Conclusions Missing data may affect publication of PROs. Extent of inclusion of SPIRIT-PRO protocol items and PROs as primary endpoints may improve data completeness. Preliminary evidence from the study suggests a future larger study examining the relationship between PRO completion and publication is warranted.

Osteomyelitis of the sternal bone is very rare and is usually secondary to trauma or surgery. Primary sternal osteomyelitis and secondary sternal osteomyelitis commonly are caused by Staphylococcus spp, and in drug addicts by Pseudomonas aerugenosa, while in sickle cell anemic children, Salmonella spp are mostly implicated. We, therefore, present an unusual causative organism, Streptococcal spp in a sickle cell anemic child.

The need to further ascertain the quality of fishmeal with biological indicators has poised this study to determine the biological characterisation of formulated diets with supplemented insect protein (variegated grasshopper and American cockroach). The diets (A–F) were prepared with local ingredients (A, 100% grasshopper meal; B, 100% fishmeal; C, 1:1 grasshopper:fishmeal; D, 1:1 cockroach:fishmeal; E, 100% cockroach meal; F, commercial diet). Samples of prepared diets ready to be stored for use were subjected to bacteria and fungi test. Diet F recorded the highest (4.60±1.10×102 cfu g–1) total viable bacteria count. The highest (3.00±0.05×102 cfu g–1) fungi count was recorded in diet A. Six probiotics bacteria were isolated from the diets. Lactobacillus delbrueckii subsp. bulgaricus was only isolated in grasshopper containing diets; as Pediococcus pentosaceus, Bifidobacterium longum, Mycobacterium marinum, Bacillus subtilisand, Lactococcocus lactis were only isolated in diets F, E, D, A and B respectively. Two pathogenic bacteria isolated were Streptoccoci pyogenes and Staphylococcus aureus. Aspergillus flavus and Penicillum sp. are the two species of fungi isolated from diet A, and diets C and E respectively. The diets with insect proteins were rich in probiotic bacteria than other diets may be considered to replace fishmeal in fish diet.

Abstract Background There are a growing number of mHealth tools for breast cancer patients but a lack of scientific evidence for their effects. Recent studies have shown a mix of positive and negative impacts on users. Here we will assess the impact of OWise Breast Cancer, a mobile application for self-monitoring symptoms and managing care, on the process of self-management. Methods This randomized controlled trial with early stage breast cancer patients will assess the effect of OWise use on patient activation at 3 months from diagnosis measured by the PAM-13 questionnaire. We will also assess differences in changes in health-related quality of life, psychological distress, health status, and National Health Service (NHS) health resource utilization over the first year from diagnosis. Participants will be randomly allocated (1:1) to standard care or standard care plus OWise. Participants will complete questionnaires before starting anti-cancer treatment and at 3, 6, and 12 months from diagnosis. Clinical and patient-reported outcome data will be linked to health resource utilization data from Discover, an integrated care record of primary, secondary, and social care in North West London. We will measure contamination in the control group and adjust the sample size to mitigate the dilution of effect estimates. A per-protocol analysis will be conducted as a sensitivity analysis to assess robustness of the primary results. Discussion This study aims to generate evidence for the effectiveness of OWise at improving patient activation for women with early-stage breast cancer. The results will show the impact of using the tool at the patient level and the NHS health system level. The outcomes of the study will have implications for the application of OWise across the NHS for breast cancer patients and expansion into other tumor types. Assessing publicly available mHealth tools poses a challenge to trialists due to the risk of contamination. Here we apply various methods to measure, mitigate, and assess the effects of contamination. Trial registration The study was registered at clincaltrials.gov (NCT03866655) on 7 March 2019.

Background: Ado-trastuzumab emtansine (T-DM1) is standard of care for patients with advanced HER2+ breast cancer who relapse within 6 months of adjuvant trastuzumab or progress on first-line anti-HER2 therapy. We evaluated its safety and efficacy in our real-world population. Methods: We identified patients on T-DM1 from 01/01/2014 to 12/03/2018 from our electronic records. Patients’, tumour characteristics, safety and efficacy outcomes were recorded. Chi-squared/Fishers exact test and Kaplan-Meier methods were utilised. Results: 128 patients receiving T-DM1 were included in the analysis with a median age of 55 years (26–85). 89.8% of patients had ECOG PS 0-1 and 21.1% had presented with de novo metastatic disease. 57.8% had ER-positive disease and 38.3% central nervous system involvement. 88.3% of patients had received trastuzumab for advanced disease (with pertuzumab in 28.9%) and 11.7% had only received trastuzumab in the adjuvant setting.Grade ≥3 adverse events occurred in 35.9% of patients. These were liver toxicity (19.5%), anaemia (6.2%) and thrombocytopenia (4.7%). Peripheral neuropathy of any grade was reported in 21.9% of cases, bleeding in 9.4% and ejection fraction decline in 5 patients.Median progression-free survival was 8.7 months and overall survival 20.4 months. Prior pertuzumab did not influence survival outcomes. Conclusions: The safety of T-DM1 in our population is similar to available literature, although we observed higher rates of peripheral neuropathy and deranged liver function. These findings are relevant for the potential role of TDM-1 in the curative setting.

The effect of sublethal concentration (0.00, 2.00, 4.00 and 8.00 mg/l) of chromium was determined on the activities of some enzymes (creatine-kinase, lactate dehydrogenase, cholinesterase, gamma glutamyltransferase) in the plasma, liver and kidney of the exposed juvenile African Catfish Clarias gariepinus (length 23.00�0.86 cm and weight 96.97�5.31 g respectively) after the 7 days exposure period. The activity of lactate dehydrogenase was significantly (p0.05) in plasma and liver and a significant decrease (p0.05) in plasma, liver and kidney expect liver creatine-kinase that was significantly decreased. Generally, the activities of the determined enzymes were most significant in the liver than in plasma and kidney. Therefore, sublethal concentrations of chromium have some deleterious effect on the basic activities of enzymes of the plasma, liver and kidney of Clarias gariepinus as revealed in this investigation.

The aim of this work was to study the effect of tobacco (Nicotiana tobaccum) leaf dust at sublethal concentrations (375.6, 187.8, 93.9 0.0mg/L) on biochemical parameters of Hybrid catfish in a static semi-renewable bioassay system with the aim to ascertain its effect on the test fish after 14 days exposure period. The effects of the plant dust on the test fish was dose-dependent, revealing significant difference in albumin, glucose, triglyceride, cholesterol, urea, and uric acid of the serum, liver and kidney; total protein and globulin of serum and kidney and creatinine and calcium of the serum while insignificant difference were observed for calcium and creatinine in liver and kidney and total protein and globulin in liver compared to the control. The effect of the plant dust was most pronounced in the serum, less in the kidney and least in the liver. However, the monitored water quality parameters revealed that the plant dust had effects on primary productivity, thus the biodiversity of organisms.

Abstract Background This study was designed to examine the knowledge, attitude and beliefs about causes, manifestations and treatment of mental illness among adults in a rural community in northern Nigeria. Methods A cross sectional study design was used. A pre-tested, semi-structured questionnaire was administered to 250 adults residing in Karfi village, northern Nigeria. Results The most common symptoms proffered by respondents as manifestations of mental illness included aggression/destructiveness (22.0%), loquaciousness (21.2%), eccentric behavior (16.1%) and wandering (13.3%). Drug misuse including alcohol, cannabis, and other street drugs was identified in 34.3% of the responses as a major cause of mental illness, followed by divine wrath/ God's will (19%), and magic/spirit possession (18.0%). About 46% of respondents preferred orthodox medical care for the mentally sick while 34% were more inclined to spiritual healing. Almost half of the respondents harbored negative feelings towards the mentally ill. Literate respondents were seven times more likely to exhibit positive feelings towards the mentally ill as compared to non-literate subjects (OR = 7.6, 95% confidence interval = 3.8–15.1). Conclusions Our study demonstrates the need for community educational programs in Nigeria aimed at demystifying mental illness. A better understanding of mental disorders among the public would allay fear and mistrust about mentally ill persons in the community as well as lessen stigmatization towards such persons.

Postburn flexion contracture of the hand in children constitutes a significant proportion of postburn complications. We compared the early clinical outcomes of reconstruction of pediatric postburn flexion contracture of the digits of the hand using tourniquet or tumescent technique. A prospective randomized study of pediatric patients requiring contracture release and wound resurfacing with full-thickness skin graft between September 2020 and August 2021. Patients were randomized into groups of either tourniquet or tumescent technique for contracture release. The surface area of graft take and total active motion across joints were the outcome measures. Student t test and chi-square test were performed. Twenty-two patients were randomized into either group. The mean age of the participants was 6.09 ± 2.41 years, mostly males 31 (72.1%). A grade 3 flexion contracture was the most common (72.1%). Ninety-four digits and 178 joints were operated on, with the proximal interphalangeal joint being the most common (48.9%). The mean surface area of graft take on postoperative day 10 was significantly higher for the tumescent group than the tourniquet group, P =.001. The total active motion across the joints at 6 and 9 weeks postoperative showed a strong correlation between the total active motion across joints and the technique of release, P =.004 and.001, respectively. Tumescent technique is a feasible alternative to the tourniquet method for postburn flexion contracture release of the digits in the pediatric burned hand. [ABSTRACT FROM AUTHOR]
