Protektem pikinini blong yu trial: protocol for a single arm field trial to assess the effectiveness of treating-all pregnant women with hepatitis B infection with tenofovir prophylaxis to prevent mother-to-child transmission in Vanuatu, 2024-2025.

Background: Hepatitis B infection is a major public health concern in Vanuatu, with approximately 9% of the general population estimated to be living with chronic hepatitis B. Most new infections are due to mother-to-child transmission (MTCT). Hepatitis B vaccination is available in Vanuatu, but coverage rates for first dose within 24 h of birth and third dose are suboptimal.

Antimicrobial, antioxidant activities, and total phenolic contents of Pycnanthus angolensis Sap and Cryptolepis sanguinolenta root extracts.

The death of many people in tropical countries can be attributed to microbial infection, probably, because synthetic antibiotics are failing in the treatment of most microbial infections, attributed to the ability of the microorganisms to mutate and adapt to harsh conditions. This study evaluated, in vitro, the antimicrobial activities, antioxidant potentials, and the total phenolic as well as phytochemical contents of aqueous and ethanol extracts of the root of Cryptolepis sanguinolenta (Lindl.) and the crude sap of Pycnanthus angolensis (Welw) using selected standard bacteria strains (Staphylococcus aureus (ATCC 25,923), Staphylococcus saprophyticus (ATCC 15,305), Escherichia coli (ATCC 25,922), Salmonella typhi (ATCC 19,430), Pseudomonas aeruginosa (ATCC 27,853), and Proteus mirabilis (ATCC 49,565).

Early peripheral blood MCEMP1 and HLA-DRA expression predicts COVID-19 prognosis.

Background: Mass vaccination has dramatically reduced the incidence of severe COVID-19, with most cases now presenting as self-limiting upper respiratory tract infections. However, those with co-morbidities, the elderly and immunocompromised, as well as the unvaccinated, remain disproportionately vulnerable to severe COVID-19 and its sequelae. Furthermore, as the effectiveness of vaccination wanes with time, immune escape SARS-CoV-2 variants could emerge to cause severe COVID-19.

Adverse effects following anti-COVID-19 vaccination with mRNA-based BNT162b2 are alleviated by altering the route of administration and correlate with baseline enrichment of T and NK cell genes.

Ensuring high vaccination and even booster vaccination coverage is critical in preventing severe Coronavirus Disease 2019 (COVID-19). Among the various COVID-19 vaccines currently in use, the mRNA vaccines have shown remarkable effectiveness. However, systemic adverse events (AEs), such as postvaccination fatigue, are prevalent following mRNA vaccination, and the underpinnings of which are not understood.

Development of PARcific Approach: Participatory Action Research Methodology for Collectivist Health Research.

This article explores the evolution of a novel approach designed to advance qualitative methods in cross-cultural health research. This methodology was developed by synthesising several research methods and involved in-depth stakeholder consultation with participants of a Pacific-based nursing and midwifery health leadership program. Many of these participants played a crucial role in creating, exploring and evaluating several research methods and implementing and evaluating this co-designed research methodology.

Development Practices in Senior Nursing and Midwifery Leadership: Pathways to Improvement in South Pacific Health Policy.

The Pacific Islands countries consist of thousands of isolated islands with a combined population of over 10 million people. It is a heterogeneous and diverse region culturally, linguistically economically and politically. Health challenges are considerable and healthcare systems are often overstretched.

F-fluorodeoxyglucose positron emission tomography as a window into human dengue pathophysiology.

In mouse models of dengue virus (DENV) infection, F-FDG PET is able to sensitively detect tissue-specific sites of inflammation and disease activity, as well as track therapeutic response to anti- DENV agents. However, the use of F-FDG PET to study the pathogenesis of inflammation and disease activity in DENV infection in humans, has not been clinically validated. Here we report the F-FDG PET imaging results of two patients during the febrile phase of acute DENV infection, paired with serial serum viral load, NS1 and proinflammatory cytokine measurements.

Iohexol assay for direct determination of glomerular filtration rate: optimization and development of an HPLC-UV method for measurement in serum and urine.

Determination of glomerular filtration rate (GFR) is considered the best indicator of renal function. Iohexol, a non-ionic contrast agent, is currently considered to be a reference marker since it meets all the requirements of an ideal GFR marker. The aim of our work is to develop and optimize a method for iohexol measurement by HPLC-UV.

Adapted cognitive-behavioral therapy for religious individuals with mental disorder: a systematic review.

Cognitive-behavioral therapy (CBT) is considered an evidence-based psychological intervention for various mental disorders. However, mental health clinicians should be cognizant of the population that was used to validate the intervention and assess its acceptability to a target group that is culturally different. We systematically reviewed published empirical studies of CBT adapted for religious individuals with mental disorder to determine the extent to which religiously modified CBT can be considered an empirically supported treatment following the criteria delineated by the American Psychological Association Task Force on Promotion and Dissemination of Psychological Procedures.

Management of cutaneous human papillomavirus infection: surgery.

Surgical management is typically required when the clinician encounters an increased quantity of warts, large surface areas of affected, or when malignant transformation is suspected. Basic surgical techniques, such as cryosurgery, electrosurgery and surgical excision, are successful and relatively quick methods for removing warts and uncomplicated cutaneous malignancies. Mohs micrographic surgery is an amenable option when cutaneous malignancies are located in high-risk areas such as periocular or perinasal regions, lips, ears, digits and genitalia, tend to be larger in size, are recurrent, possess aggressive histological features, such as moderate-to-poor differentiation, or demonstrate perineural invasion.

Imaging of Mohs micrographic surgery sections using full-field optical coherence tomography: a pilot study.

Background: Full-field optical coherence tomography (FF-OCT) is a new noninvasive imaging technique that can see down to the cellular level without tissue preparation or contrast agents.

Objective: To use FF-OCT to image Mohs micrographic surgery specimens and verify the ability of a dermatopathologist to identify or exclude malignancy.

Materials And Methods: Two Mohs surgeons supplied 18 Mohs sections from 11 patients.

Subungual squamous cell carcinoma after organ transplantation.

It is accepted that immunosuppressant therapy after organ transplantation is associated with an increase risk of neoplasm. Subungual squamous cell carcinoma of the toe is a rare condition and has not previously been reported, to our knowledge, in patients undergoing immunosuppressant therapy. The objective of this case study is to report the clinical and histopathologic findings and the multidisciplinary treatment approach for a case of subungual squamous cell carcinoma of the toe in an organ transplant recipient undergoing immunosuppressant drug therapy.

Elevation of Nitric Oxide Synthase Activity by Dimethyladenosine from Silkworm Pupae in Aged Rats.

This study examined the mechanisms underlying the effects of the vasorelaxation active substance (VAS), dimethyladenosine-5'-L-arabinose, and its partial purification fraction on nitric oxide synthase in improving erectile dysfunction with particular focus on the nitric oxide (NO)-cGMP pathways. Two rat models, 9-month-old SD rats and 11-month-old SD rats, were given VAS (40 mg/kg per day) for 4 days, The aqueous fraction of silworm male pupae extract; semi-purified VAS (100 mg/kg per day) for 10 days, respectively. The NOS activities of the following three enzymes were examined: neuronal NO synthase (NOS), inducible NOS (NOS), endothelial NOS (NOS), vascular endothelial growth factor on endothelial cells (VEGF) and anti-inflammation effect of Tumor necrosis factor-α.

Epithelial and endothelial barriers in the olfactory region of the nasal cavity of the rat.

The olfactory ensheathing (glial) cells (OECs) have been identified to be useful candidate cells to support regeneration after being transplanted into injured fiber tracts of the central nervous system. We investigated by means of immunocytochemistry and freeze-fracturing the morphology and molecular composition of OEC tight junctions in the rat olfactory system. In addition, we tested the hypothesis whether tight junctions and orthogonal arrays of particles (OAPs) which contain the water channel protein aquaporin-4 (AQP4), are mutually exclusive as suggested in previous studies.

Perifolliculitis capitis abscedens et suffodiens in an 18-year-old Aboriginal Canadian patient: case report and review of the literature.

Background: Perifolliculitis capitis abscedens et suffodiens (PCAS) is a suppurative process that involves the scalp, eventually resulting in extensive scarring and irreversible alopecia. This condition often presents in males of African American origin.

Objective: This article describes the clinical presentation, diagnosis, and treatment of an Aboriginal Canadian male suffering from PCAS.

Delayed cutaneous wound healing in mice lacking solute carrier 11a1 (formerly Nramp1): correlation with decreased expression of secretory leukocyte protease inhibitor.

Control of macrophage functions by natural resistance-associated macrophage protein 1 (NRAMP1) has proven to be important for murine resistance to several intracellular pathogens, including Mycobacterium bovis BCG and Salmonella typhimurium, although the exact molecular mechanism of its action remains unknown. We identified secretory leukocyte protease inhibitor (SLPI) as a novel candidate gene whose expression is dependent on Nramp1 gene expression using B10A.Nramp1+/+ and B10A.

[Conjunctival semi-lunar fold nevus of presumed late onset].

Conjunctival nevi are lesions observed commonly occasionnally and can be found later in a life. Such a lesion was observed on the conjunctival semilunar fold in a 76-year-old female patient. It was oval in shape, pigmented, and was mainly visible when the affected eye was in abduction.

[A cutaneous horn of the free margin of the eyelid: an anatomical and clinical observation].

A cutaneous horn was observed close to the free margin of the inferior right eyelid in a 26-year-old-male patient. A minimal resection was primarily performed. Histopathologic study disclosed a precancerous keratosis.

[Multilocular eyelid hidrocystoma: an anatomical and clinical observation].

A cystic cutaneous mass was observed on the lateral canthus of the left eyelid in a 25-year-old woman, 2 years after being operated on for a lesion that had existed in the same area several years before, but the patient could not identify its nature. The present mass appeared as a well-circumscribed bluish cystic lesion. A surgical resection was performed; pathological analysis disclosed a cystic sweat tumor composed of several contiguous cysts.

[Actinic keratosis seborrheic wart and nevus: three distinct cutaneous eyelid skin lesions in a single patient].

A 67-year-old woman had three different tumors of the eyelids. The most prominent one was a nevus of the free margin of the inferior left eyelid. The nevus was followed for 18 months without change while two epidermal papillomatous tumors grew and were surgically removed.
