Exploring ChatGPT's Potential in Facilitating Adaptation of Clinical Guidelines: A Case Study of Diabetic Ketoacidosis Guidelines.

Background This study aimed to evaluate the efficacy of ChatGPT, an advanced natural language processing model, in adapting and synthesizing clinical guidelines for diabetic ketoacidosis (DKA) by comparing and contrasting different guideline sources. Methodology We employed a comprehensive comparison approach and examined three reputable guideline sources: Diabetes Canada Clinical Practice Guidelines Expert Committee (2018), Emergency Management of Hyperglycaemia in Primary Care, and Joint British Diabetes Societies (JBDS) 02 The Management of Diabetic Ketoacidosis in Adults. Data extraction focused on diagnostic criteria, risk factors, signs and symptoms, investigations, and treatment recommendations.

Breast Cancer Knowledge, Attitudes and Practices amongst Women in Qatar.

This cross-sectional study examines knowledge, attitudes, and practices surrounding breast cancer awareness and screening among women residents in Qatar. Females, >18 years old, registered with the Primary Health Care Corporation were invited to complete an Arabic or English online survey using a modified version of the Breast Cancer Awareness Module. Of the 9008 participants, 69% report awareness of breast cancer warning signs, but the results did not substantiate these claims.

Diagnostic accuracy of the Patient Health Questionnaire 2 (PHQ-2) in Qatar's primary care settings.

This cross-sectional study was designed to establish diagnostic accuracy of the Patient Health Questionnaire 2 in Qatar's primary care population. The data required for the study were anonymously extracted from Qatar's primary care electronic medical record system. The sensitivity, specificity, predictive values, negative values and optimal cut-off points were calculated for the tool.

Haemoglobin cut-off values for the diagnosis of anaemia in preschool-age children.

Background: The World Health Organisation (WHO) suggests haemoglobin that (Hgb) cut-off levels below 2SD from the population mean to initiate anaemia investigations. In the absence of epidemiological data, Hgb less than 11 g/dL is considered abnormal in children up to the age of 59 months (4 years and eleven months).

Objectives: This study reports on the Hgb cut-off levels among children at 1 and 4 years of age.

Estimating point prevalence of COVID-19 in Qatar's primary care registered population: an RT-PCR drive-through study protocol.

Background: The first COVID-19 cases in Qatar were reported on 29 February 2020. As the epidemic progresses, essential epidemiological information is needed to facilitate monitoring of COVID-19 in the population and plan the pandemic response in Qatar.

Aim: The primary aim of this cross-sectional study is to estimate the point prevalence of COVID-19 in Qatar's primary care registered population.

Haematological abnormalities and risk of COVID-19 infection in adult patients attending primary healthcare settings.

Centres for Disease Control and prevention (CDC) reports that there are limited data and information about the impact of underlying medical conditions and the risk of infection. To date, there are no studies that report on the risk of infection among patients with haematological diseases or abnormalities. This cross-sectional study reports on the baseline complete blood count in patients attending publicly funded primary care settings with a diagnosis of suspected COVID-19 infections in the state of Qatar.

Significance of Serum Adiponectin and Insulin Resistance Levels in Diagnosis of Egyptian Patients with Chronic Liver Disease and HCC.

One possible hypothesis for pathogenesis of hepatocellular carcinoma is deregulated expressed adipokines (adipose tissue cytokines). Chronic inflammation in the cirrhotic liver adipose tissue is associated with a modification in adipokine secretion. Changes in serum levels of adiponectin are known to be associated with the development of insulin resistance.

Caffeine Toxicity Following Ingestion of an Exercise Supplement by a Patient with Type 1 Diabetes.

Unlabelled: We report the case of a patient with type 1 diabetes who developed acute severe diabetic ketoacidosis following ingestion of an energy supplement containing caffeine. Some 95% of the US adult population consume caffeine, and the general perception is that there are no negative consequences for health. The upper limit of safe consumption is less than 400 mg per day.

An exact model for predicting tablet and blend content uniformity based on the theory of fluctuations in mixtures.

Content uniformity (CU) of tablets is a critical property that needs to be well controlled in pharmaceutical products. Methods that predict the CU accurately can greatly help in reducing the development efforts. This article presents a statistical mechanical framework for predicting CU based on first principles at the molecular level.

Development of tamper deterrent formulations: state of the pharmaceutical industry.

Prescription drug abuse is a significant and growing health and socio-economical problem in the US and the world. According to the 2008 UN World Drug Report, the number of people who have consumed an illicit drug at least once in 2006/2007 reached 240 million, roughly 6% of the world population aged 15 to 64. In the last few years, pharmaceutical manufacturers started developing new formulations specifically designed to provide tamper deterrent features.

Fentanyl buccal tablet for the treatment of breakthrough pain: pharmacokinetics of buccal mucosa delivery and clinical efficacy.

The treatment of breakthrough pain (BTP), a transitory exacerbation of pain that occurs on a background of otherwise-controlled, persistent pain, requires an opioid formulation and/or method of administration that can provide rapid and extensive systemic exposure. Fentanyl buccal tablet (FBT; FENTORA((R)), Cephalon, Inc.) employs OraVescent((R)) drug delivery technology, which enhances the rate and extent of fentanyl absorption.

A study of the pharmacodynamic differences between immediate and extended release bumetanide formulations.

Optimized bumetanide extended (ER) and immediate release (IR) formulations were developed using fluid bed layering and coating techniques. We postulated that the ER bumetanide formulation would have more effective and sustained diuretic and saluretic effects than IR. The diuretic/saluretic effects of both formulations were measured in rabbits (n=8) for two days after dosing with 1mg/kg bumetanide.

Effect of curing conditions and plasticizer level on the release of highly lipophilic drug from coated multiparticulate drug delivery system.

The study aimed to investigate the effect of triethyl citrate (TEC) plasticizer level (10, 15, and 20%), curing temperature (40, 50, and 60 degrees C) and time (0 to 168 h) on the release of a highly lipophilic drug bumetanide from pellets coated with methacrylate ester copolymer (Eudragit RS). Bumetanide was layered onto sugar pellets followed by coating with 6% Eudragit RS with and without hydroxypropyl methyl cellulose (HPMC) seal coat using Wurster Fluid Bed equipment. Coated pellets were stored for 3 months at room temperature and the release was tested in USP purified water.
