BackgroundCongenital anomalies are the fifth leading cause of mortality in children younger than 5 years globally. Many gastrointestinal congenital fatal without timely access to neonatal surgical care, but few studies have been done on these conditions low-income and middle-income countries (LMICs). We compared outcomes seven most common low-income, middle-income, high-income globally, identified factors associated with mortality.MethodsWe did a multicentre, international prospective cohort...
Bone densitometry (L2-L4) was performed on 10 postmenopausal women with breast cancer after 0, 6, and 12 months of tamoxifen treatment; the results were compared data from normal controls. The patients controls differed significantly at 6 (P<.05) (P<.003) months. group showed a nonsignificant mean gain in bone mineral density treatment (+0.024 ± 0.014 +0.022 0.018 g/cm2, respectively), whereas loss mass (−0.012 g/cm2 statistically significant (−0.024 0.01 g/cm2). These preliminary suggest...
The 2015 Lancet Commission on global surgery identified and anaesthesia as indispensable parts of holistic health-care systems. However, COVID-19 exposed the fragility planned surgical services around world, which have also been neglected in pandemic recovery planning. This study aimed to develop validate a novel index support local elective system strengthening address growing backlogs.
Noncyclooxygenase metabolites of arachidonic acid may be potent modulators the mitogenic response renal mesangial cells to vasoactive peptide arginine vasopressin (AVP). Since Ca2+ is a critical second messenger in AVP, and has been implicated regulation growth, we determined whether noncyclooxygenase altered phospholipase C-Ca2+ signalling cascade which activated by AVP. Pretreatment for 10 min with lipoxygenase cytochrome P450 monooxygenase inhibitors, nordihydroguaiaretic (NDGA, 10(-5) M)...
Telemedicine is being adopted for postoperative surveillance but requires evaluation efficacy. This study tested a telephone Wound Healing Questionnaire (WHQ) to diagnose surgical site infection (SSI) after abdominal surgery in low- and middle-income countries.
Abstract Background The Bluebelle Wound Healing Questionnaire (WHQ) is a universal-reporter outcome measure developed in the UK for remote detection of surgical-site infection after abdominal surgery. This study aimed to explore cross-cultural equivalence, acceptability, and content validity WHQ use across low- middle-income countries, make recommendations its adaptation. Methods was mixed-methods within trial (SWAT) embedded an international randomized trial, conducted according best...
BACKGROUND: Data on colorectal cancer (CRC) diagnosis to treatment interval (DTI), an index of quality assurance in high-income countries (HICs) is lacking South Africa. This study aimed determine DTIs and their impact CRC survival a African cohort METHODS: Participants (n = 289) from the Colorectal Cancer Africa (CRCSA) were identified for inclusion. The DTI was defined as duration between initial definitive categorised into approximate quartiles (Q1-4). 0-14 days, 15-28 29-70 > 71 days....
Introduction In Brazil, approximately 5% are born with a congenital disorder, potentially fatal without surgery. This study aims to evaluate the relationship between gastrointestinal malformation (GICM) mortality, health indicators, and socioeconomic factors in Brazil. Methods GICM admissions (Q39–Q45) 2012 2019 were collected using national databases. Patient demographics, factors, clinical management, outcomes, healthcare workforce density also accounted for. Pediatric Surgical Workforce...
Background Despite high-level commitment from governments, national surgical healthcare policy development has been slower than expected across the Southern African Development Community (SADC). This regional survey study aims to identify perceived barriers formulation and, where applicable, implementation. Methods A combination of convenience, purposive and snowball sampling techniques were used distribute an electronic SADC care stakeholders. Adaptive questioning was utilised evaluate...
Introduction The shift from subscription-based to open-access (OA) publishing sought democratize scientific knowledge by eliminating access barriers. However, article processing charges (APCs) have raised concerns about equity, particularly for researchers low- and middle-income countries (LMICs). APCs costs readers authors, potentially limiting the ability of disseminate their work. This study aimed quantify effect on equity in global surgery examining current APC association with journal...
On September 29, 2023, the Republic of Ecuador convened a meeting to address surgical system strengthening and urge political leaders invest in infrastructure. The included experts health diplomacy, innovative financing, implementation strategy national plans. event occurred parallel with Sixtieth Directing Council Pan American Health Organization, Seventy-fifth session World Organization Regional Committee for Americas. centered around four major areas: (i) building capacity as means...
ABSTRACT Background The Lancet Commission on Global Surgery (LCoGS) emphasized the need for six core indicators to track progress toward safe, affordable, and timely surgical care. In 2016, four of these were integrated into World Development Indicators (WDI) facilitate global tracking system performance. However, impact relies accuracy frequency reported data. We aimed analyze trends in reporting WDI evaluate context countries undertaking National Surgical Plans (NSPs). Methods Data...
The osmotic fragility of blood can be numerically defined by measuring the change in osmolarity (Δ mOsm) required to hemolyze 50% erythrocyte population when hemolysis is proceeding at highest rate. In normal Δ mOsm = 11.8 ± 1.1 mOsm. all dyscrasias which were studied this index was significantly different from normal. It abnormal bearers sickle cell or thalassemia trait. also Hodgkin's disease and cancer patients.
A randomized, double blind crossover trial compared the antiemetic effects of alizapride, a benzamide, and prochlorperazine, phenothiazine, both administered intravenously to 32 patients treated with chemotherapy combinations containing cisplatin. The total dose alizapride each patient was 14 mg/kg, prochlorperazine .56 divided in five doses. Although resulted complete protection against emesis 31% during their first course cisplatin therapy, 42% those who received had or more episodes...
