Impact of empagliflozin add-on therapy on quality of life in patients of type 2 diabetes mellitus with hypertension: A prospective study.

Background: Diabetes has a negative impact on patient's quality of life (QoL). Comorbidities and polypharmacy further worsen their QoL. Thus, in addition to glycemic control, assessment of QoL is also gaining importance. Objective: The objective of this study was to evaluate QoL in patients of type 2 diabetes mellitus (T2DM) with hypertension after add-on empagliflozin to triple drug therapy (metformin, teneligliptin, and glimepiride). Materials and Methods: A prospective research was done on T2DM patients with hypertension, who visited a tertiary care referral institute's endocrine outpatient clinic. For 3 months, empagliflozin, 25 mg once daily, was administered as an add-on treatment with metformin, teneligliptin, and glimepiride. In addition to clinical assessment, an Urdu-translated QoL instrument for Indian diabetes patients was used to conduct QoL study. The QoL outcomes prior to empagliflozin add-on were compared with those obtained at the conclusion of the 3 months of treatment. Results: Empagliflozin as an add-on therapy significantly improved various aspects of QoL like role limitation due to physical health, physical endurance, general health, symptom botherness, financial worries, emotional/mental health, and diet satisfaction (P < 0.001). It also improved glycemic and blood pressure parameters significantly. Conclusion: QoL is an essential measure with respect to patient-centered treatment approach. Empagliflozin, as an add-on medication, improved QoL, glycemic parameters and blood pressure in T2DM patients with hypertension. It can be recommended as an add-on, but more research with a larger sample size is required.

Correlation between Sleep Duration and Risk of Stroke.

Modern lifestyle and job requirements have changed the sleep habits of most of the adult population. Various population-based studies have associated an increase in mortality with either shortened sleep or long sleep duration. Thus a U-shaped relationship between sleep duration and all-cause mortality in both men and women has been suggested. Several studies have found an association between sleep duration and risk of cardiovascular diseases also. Efforts to understand the etiology of stroke have indicated an association between sleep and stroke too. Obstructive sleep apnea, a sleep-related disorder, has been reported to significantly increase the risk of stroke. Moreover, many studies have shown that both short and long sleep durations are related to increased likelihood of diabetes and hypertension, which themselves are risk factors for stroke. Therefore, this review focuses on the correlation between sleep duration and risk of stroke based on the experimental and epidemiologic studies. Although a few experimental studies have reported that partial sleep deprivation may reduce stroke incidence and severity, yet, most experimental and observational studies have indicated a strong association between short/long sleep durations and higher risk of stroke.

Role of drugs in the prevention and amelioration of radiation induced toxic effects.

As the use of radiation technology for nuclear warfare or for the benefits of mankind (e.g. in radiotherapy or radio-diagnosis) is increasing tremendously, the risk of associated side effects is becoming a cause of concern. These effects, ranging from nausea/vomiting to death, may result from accidental or deliberate exposure and begin in seconds. Through this review paper, efforts have been done to critically review different compounds which have been investigated as radioprotectors and radiation mitigators. Radioprotectors are compounds which are administered just before or at the time of irradiation so as to minimize the radiation induced damage to normal tissues. And radiation mitigators are the compounds which can even minimize or ameliorate post irradiaion-toxicity provided they are administered before the onset of toxic symptoms. A variety of agents have been investigated for their preventive and ameliorative potential against radiation induced toxic effects. This review article has focused on various aspects of the promising representative agents belonging to different classes of radioprotectors and mitigators. Many compounds have shown promising results, but till date only amifostine and palifermin are clinically approved by FDA. To fill this void in pharmacological armamentarium, focus should be shifted towards novel approaches.

Chemopreventive effect of artesunate in 1,2-dimethylhydrazine-induced rat colon carcinogenesis.

Artesunate (ART) is a semisynthetic derivative of artemisinin. Artemisinin and its derivatives have shown profound cytotoxicity and antitumor activity in addition to antimalarial activity in various studies. As the in vivo chemopreventive efficacy of ART in colon carcinogenesis has not been investigated so far, the aim of the current study was to study the chemopreventive effect of ART in 1,2-dimethylhydrazine (DMH)-induced rat colon carcinogenesis. Animals were divided into four groups (n = 6): Group I - vehicle (1 mM ethylenediaminetetraacetic acid), Group II - DMH (20 mg/kg), Group III - DMH + 5-fluorouracil (81 mg/kg), Group IV - DMH + ART (6.7 mg/kg). After completion of 15 weeks of treatment, rats were sacrificed under ether anesthesia by cervical dislocation for assessment of lipid peroxidation (LPO), antioxidant status, average number of aberrant crypt foci (ACF), and cytokine levels. ART administration significantly decreased the average number of ACF/microscopic field. Similarly, LPO level was decreased and antioxidant activities were enhanced after ART treatment. ART decreased the levels of proinflammatory cytokines and induced apoptosis in the colons of DMH-treated rats. The results of this study suggest that ART has a beneficial effect against chemically induced colonic preneoplastic progression in rats.

Effect of goat milk on hepatotoxicity induced by antitubercular drugs in rats.

Aim of the present study was to assess the hepatoprotective activity of goat milk on antitubercular drug-induced hepatotoxicity in rats. Hepatotoxicity was induced in rats using a combination of isoniazid, rifampicin, and pyrazinamide given orally as a suspension for 30 days. Treatment groups received goat milk along with antitubercular drugs. Liver damage was assessed using biochemical and histological parameters. Administration of goat milk (20 mL/kg) along with antitubercular drugs (Group III) reversed the levels of serum alanine aminotransferase (82 ± 25.1 vs. 128.8 ± 8.9 units/L) and aspartate aminotransferase (174.7 ± 31.5 vs. 296.4 ± 56.4 units/L, p<0.01) compared with antitubercular drug treatment Group II. There was a significant decrease in serum alanine aminotransferase (41.8 ± 4.1 vs. 128.8 ± 8.9 ​ units/L, p<0.01) and aspartate aminotransferase (128.8 ± 8.54 vs. 296.4 ± 56.4 units/L, p<0.001) levels in Group IV (goat milk 40 mL/kg) compared with antitubercular drug treatment Group II. Goat milk (20 mL/kg and 40 mL/kg) was effective in reversing the rise in malondialdehyde level compared with the antitubercular drug suspension groups (58.5 ± 2 vs. 89.88 ± 2.42 µmol/mL of tissue homogenate, p<0.001 and 69.7 ± 0.78 vs. 89.88 ± 2.42 µmol/mL of tissue homogenate, p<0.001, respectively). Similarly, both doses of milk significantly prevented a fall in superoxide dismutase level (6.23 ± 0.29 vs. 3.1 ± 0.288 units/mL, p<0.001 and 7.8 ± 0.392 vs. 3.1 ± 0.288 units/mL, p<0.001) compared with the group receiving antitubercular drugs alone. Histological examination indicated that goat milk reduced inflammation and necrotic changes in hepatocytes in the treatment groups. The results indicated that goat milk prevented the antitubercular drug-induced hepatotoxicity and is an effective hepatoprotective agent.
