UV-Spectrophotometric Determination of Telmisartan and Hydrochlorothiazide in Combined Tablet Dosage Form Using Simultaneous Equation Method

A UV spectrophotometric method was developed for the estimation of Telmisartan and Hydrochlorothiazide in Combined Tablet Dosage Form Using Simultaneous Equation Method. The drug obeyed the Beers law and shows good correlation near to r 2 = 0.999 for Telmisartan and for Hydrochlorothiazide r 2 =0.999.Absorption maxima of Telmisartan 296.8 nm and Hydrochlorothiazide 271.2 nm. Beers law was obeyed in concentration rang of 5-30 g/ml for Telmisartan and 2-12 g/ml for Hydrochlorothiazide. The method has been validated for linearity, accuracy and precision. The recovery was 99.28 % for Telmisartan and 99.26% for Hydrochlorothiazide. The developed method was found to be accurate, simple, precise, economical, and selective for simultaneous estimation of Telmisartan and Hydrochlorothiazide in tablet formulations

“We are the soul, pearl and beauty of Hindu Kush Mountains”: exploring resilience and psychological wellbeing of Kalasha, an ethnic and religious minority group in Pakistan

The Kalasha are a marginalized ethnic and religious minority group in northern Pakistan. The Kalasha minority is known for their divergent polytheistic beliefs, and represents the outliers of the collectively monotheistic Muslim population of Pakistan. This study aimed to explore the psychological resilience beliefs and lived experiences of the Kalasha and to identify cultural protective factors and indigenous beliefs that help them maintain psychological wellbeing and resilience. Seven semi-structured interviews and two focus-group discussions were conducted. The total sample consisted of 6 women and 8 men, aged 20–58 years (Mage = 36.29, SD = 12.58). The Interpretative Phenomenological Analysis qualitative method was chosen. Study findings identified that factors contributing to the wellbeing, happiness and resilience enhancement beliefs of Kalasha included five main themes, all influenced by their unique spirituality: contentment, pride in social identity, tolerance, gender collaboration and gratitude. The study also revealed the Kalasha’s perception of their marginalization related to challenges and threats. The Kalasha emphasized bringing these resilience enhancement beliefs into practice, as a mean to buffer against challenges. In conclusion, this study revealed Kalasha’s wellbeing and resilience enhancement factors, which they believed in and practiced as an element of their indigenous culture and religion

Intraperitoneal drain placement and outcomes after elective colorectal surgery: international matched, prospective, cohort study

Despite current guidelines, intraperitoneal drain placement after elective colorectal surgery remains widespread. Drains were not associated with earlier detection of intraperitoneal collections, but were associated with prolonged hospital stay and increased risk of surgical-site infections.Background Many surgeons routinely place intraperitoneal drains after elective colorectal surgery. However, enhanced recovery after surgery guidelines recommend against their routine use owing to a lack of clear clinical benefit. This study aimed to describe international variation in intraperitoneal drain placement and the safety of this practice. Methods COMPASS (COMPlicAted intra-abdominal collectionS after colorectal Surgery) was a prospective, international, cohort study which enrolled consecutive adults undergoing elective colorectal surgery (February to March 2020). The primary outcome was the rate of intraperitoneal drain placement. Secondary outcomes included: rate and time to diagnosis of postoperative intraperitoneal collections; rate of surgical site infections (SSIs); time to discharge; and 30-day major postoperative complications (Clavien-Dindo grade at least III). After propensity score matching, multivariable logistic regression and Cox proportional hazards regression were used to estimate the independent association of the secondary outcomes with drain placement. Results Overall, 1805 patients from 22 countries were included (798 women, 44.2 per cent; median age 67.0 years). The drain insertion rate was 51.9 per cent (937 patients). After matching, drains were not associated with reduced rates (odds ratio (OR) 1.33, 95 per cent c.i. 0.79 to 2.23; P = 0.287) or earlier detection (hazard ratio (HR) 0.87, 0.33 to 2.31; P = 0.780) of collections. Although not associated with worse major postoperative complications (OR 1.09, 0.68 to 1.75; P = 0.709), drains were associated with delayed hospital discharge (HR 0.58, 0.52 to 0.66; P < 0.001) and an increased risk of SSIs (OR 2.47, 1.50 to 4.05; P < 0.001). Conclusion Intraperitoneal drain placement after elective colorectal surgery is not associated with earlier detection of postoperative collections, but prolongs hospital stay and increases SSI risk

Afraid of the dark : Light acutely suppresses activity in the human amygdala

Light improves mood. The amygdala plays a critical role in regulating emotion, including fear-related responses. In rodents the amygdala receives direct light input from the retina, and light may play a role in fear-related learning. A direct effect of light on the amygdala represents a plausible mechanism of action for light’s mood-elevating effects in humans. However, the effect of light on activity in the amygdala in humans is not well understood. We examined the effect of passive dim-to-moderate white light exposure on activation of the amygdala in healthy young adults using the BOLD fMRI response (3T Siemens scanner; n = 23). Participants were exposed to alternating 30s blocks of light (10 lux or 100 lux) and dark (<1 lux), with each light intensity being presented separately. Light, compared with dark, suppressed activity in the amygdala. Moderate light exposure resulted in greater suppression of amygdala activity than dim light. Furthermore, functional connectivity between the amygdala and ventro-medial prefrontal cortex was enhanced during light relative to dark. These effects may contribute to light’s mood-elevating effects, via a reduction in negative, fear-related affect and enhanced processing of negative emotion

Design and Development of Heat Recovery System in Water Cooler

More than 15% of total energy consumption of the world is for the cooling and airconditioning application. Beign the huge contributor in consumption of electricity, these systems have the scope of developments in terms of optimum utilization of the resources. The cooling systems are improved over the years by means of design, use of different cooling mediums and th performance. The conventional water coolers are less energy efficient and the wastage of water is also the issue to be addressed. Authors have presented the improved design in terms of energy efficiency and the waste water utilization in this paper. The design fo the system components in Solid Works software is presented in the paper along with the parameter calcutions. Water and electricity are important aspects to be saved. Optimal utlistion of the electricity and water results in saving the environment, cost, and environmental hazards
