Prevalence of hypertension in diabetic patients in Pakistan

2024-06-30T04:21:31-05:00

This study highlights the prevalence of diabetes and hypertension as well as the risk factors that are linked to them. Those with diabetes are as much as four times greater likely than non-diabetics to experience hypertension. In diabetics, hypertension is substantially correlated with both obesity and dyslipidemia. Because it rarely causes symptoms, hypertension is referred to as the "silent killer" and is a serious health risk. Stress, excessive sodium intake, alcohol consumption, and physiological variables are among the factors contributing to hypertension in diabetics; genetic susceptibility, obesity, and sedentary lifestyles are all significant factors. These elements have contributed to a rise in the prevalence of hypertension in Pakistani society. Severe consequences such as congestive heart failure, renal failure, strokes, and cardiovascular disorders might result from the condition. Genetic predisposition, obesity, sedentary lifestyles, stress, high in sodium consumption, drinking alcohol, and physical characteristics are some of the factors that cause hypertension in diabetics. In Pakistani society, the incidence of hypertension has increased as a result of several factors. The condition may have severe effects, including strokes, cardiovascular illnesses, congestive heart failure, and renal failure.

Investigating the synergistic effects of resveratrol and metformin on insulin sensitivity and ovulatory function in women with PCOS

2024-07-10T06:06:28-05:00

This study explores the synergistic effects of Resveratrol and Metformin on improving insulin sensitivity and ovulatory function in women with Polycystic Ovary Syndrome (PCOS). As a complex condition, PCOS is characterized by elevated androgen levels, menstrual irregularities, and the presence of ovarian cysts, with significant impacts on reproductive and metabolic health. Addressing this, our randomized, double-blind, placebo-controlled trial involved 100 women diagnosed with PCOS. Participants were divided into two groups, one receiving Metformin alone and the other a combination of Metformin and Resveratrol. Outcomes measured included insulin sensitivity, ovulatory cycles, metabolic and hormonal profiles, and inflammatory markers. Our findings revealed that combination therapy significantly improved ovulatory function, insulin sensitivity, and reduced inflammation compared to Metformin alone. These promising results indicate the potential of combined Resveratrol and Metformin treatment in managing both metabolic and reproductive aspects of PCOS, though further research is necessary to confirm these outcomes and clarify the mechanisms at play.

Preparation of skin friendly topical gel containing betamethasone dipropionate loaded ethosomes and salicylic acid for the treatment of eczema

2024-06-13T22:16:39-05:00

Ethosomes, a lipid-based vesicular system, are a cutting-edge method for delivering medicinal drugs transdermally for either local or systemic action. Betamethasone Dipropionate ethosomes were fabricated and then these were incorporated into the final gel containing salicylic acid. Betamethasone is an anti-inflammatory agent and salicylic acid acts as a keratolytic agent. The increased drug entrapment and permeation are caused by the high ethanol content of ethosomes. By changing the proportions of ethanol and lipoid S100 in a cold method, ethosomes were created. The concentration of ethanol utilized ranged from 30 to 40%, whereas the concentration of phospholipids ranged from 3 to 5%. The characteristics of ethosomes made with 40% ethanol and 3% Lipoid S100 were improved. The size, zeta potential, entrapment efficacy, in-vitro release profile, ex-vivo skin permeation study, plus in-vitro stability investigations of the prepared Betamethasone Dipropionate ethosomes were all assessed. With an average size of 220-240nm, entrapment efficiency was 81.42-91.65%%, zeta potential was -12.91 to -14.42, and its in-vitro cumulative drug release over 12 hours was 96%. The drug penetration from the ethosomes gel formulation through the rat skin was two times more than that of the Betamethasone control gel. Ethosomes gel's rheological behaviour was evaluated, and pseudo plastic flow behaviour suggested that the formulation was suitable for topical use. Moreover, the formulations were stable at 8 °C and the ethosomes formulation demonstrated improved drug penetration through the epidermal membrane, improving the medication's bioavailability.
