Among the renewable forms of energy, solar energy is a convincing, clean energy and acceptable worldwide. Solar PV plants, both ground mounting and the rooftop, are mushrooming thought the world. One of the significant challenges is the fault identification of the solar PV module, since a vast power plant condition monitoring of individual panels is cumbersome. This paper attempts to identify the panel using a thermal imaging system and processes the thermal images using the image processing technique. An ordinary and thermal image has been processed in the image processing tool and proved that thermal images record the hot spots. Similarly, the new and aged solar photovoltaic panels were compared in the image processing technique since any fault in the panel has been recorded as hot spots. The image recorded in the aged panels records hot spots, and performance has been analyzed using conventional metrics. The experimental results have also been verified.

We evaluated the relation between components of body composition and mortality in patients with cardiovascular disease (CVD). Dual x-ray absorptiometry body composition data from the National Health and Nutrition Examination Survey 1999 to 2004 was linked to total and CVD mortality data 1999 to 2006 in 6,451 patients with CVD. Kaplan-Meier survival analysis for the end points of total and CVD mortality was plotted by quartiles of muscle mass, fat mass, and categories of body mass index (BMI). Subjects were stratified into 4 groups (low muscle/low fat mass, low muscle/high fat mass, high muscle/low fat mass, and high muscle/high fat mass). Adjusted Cox proportional hazards regression determined hazard ratios for total and CVD mortality. Rates of cardiovascular/total mortality were lower in higher quartiles of muscle mass, fat mass, and higher categories of BMI (p <0.001). The high muscle/low fat mass group had a lower risk of CVD and total mortality (risk-adjusted hazard ratios of 0.32, 95% confidence interval 0.14 to 0.73 and 0.38, 95% confidence interval 0.22 to 0.68, for CVD and total mortality, respectively). Thus, increasing fat mass, muscle mass, and BMI were all correlated with improved survival. The specific subgroup of high muscle and low fat mass had the lowest mortality risk compared with other body composition subtypes. This suggests the importance of body composition assessment in the prediction of cardiovascular and total mortality in patients with CVD.

In recent years, the integration of advanced diabetes technology into the care of individuals with diabetes has grown exponentially. Given their increasing prevalence, insulin-requiring people with diabetes may present to preoperative clinics or the operating rooms wearing such devices. While advantageous from a diabetes management perspective, for those unfamiliar with devices this can add another layer of complexity to diabetes management in both the outpatient and inpatient settings, particularly because of the rapidly evolving technology. Therefore, perioperative clinicians need to become familiar with diabetes technological advances, and device features and have an understanding of how they can be used in the perioperative period. This consensus statement aims to serve as an educational material as well as to serve as a guide to perioperative clinicians caring for patients wearing diabetes devices (insulin pumps and continuous glucose monitors). •Diabetes technology is rapidly evolving towards more automated systems for insulin delivery.•While older insulin pumps required considerable user input, newer automated systems simplify diabetes management including during the perioperative period.•Continuous glucose monitoring is not currently FDA approved for in-hospital or perioperative use, but values and trends can be useful in conjunction with point of care testing.

Prior studies on chronic systolic heart failure (HF) have demonstrated that body mass index (BMI) is inversely associated with mortality, the so-called obesity paradox. The aim of this study was to determine whether BMI influences the mortality risk in acute decompensated HF, a subject not previously studied. The Acute Decompensated Heart Failure National Registry was analyzed for acute HF hospitalizations in 263 hospitals in the United States from October 2001 through December 2004. Patients with documented height and weight were divided into BMI (measured in kilograms per square meter) quartiles. Inhospital mortality by BMI quartile for all the patients and for those with reduced (n = 43 255) and preserved (n = 37 901) systolic function was assessed. Body mass index quartiles in the 108 927 hospitalizations were QI (16.0-23.6 kg/m 2), QII (23.7-27.7 kg/m 2), QIII (27.8-33.3 kg/m 2), and QIV (33.4-60.0 kg/m 2). Patients in the higher BMI quartiles were younger, had more diabetes, and had a higher left ventricular ejection fraction. Inhospital mortality rates decreased in a near-linear fashion across successively higher BMI quartiles. After adjustments for age, sex, blood urea nitrogen, blood pressure, creatinine, sodium, heart rate, and dyspnea at rest, BMI quartile still predicted mortality risk. For every 5-U increase in BMI, the odds of risk-adjusted mortality was 10% lower (95% CI 0.88-0.93, P < .0001). In this cohort of hospitalized patients with HF, higher BMI was associated with lower inhospital mortality risk. The relationship between BMI and adverse outcomes in HF appears to be complex and deserving of further study.

[...]a safe environment system with a facility enhancement for an improved resource guarded IoT environment and open concerns are discussed. [8] Power utilized can be found by using the technologies such as GE and CMOS techniques [10, 11]. Since Power and Energy utilization are the significant parameters thus any change in the CMOS values will effect on the gate density. [...]there is a large amount of increase in gate density for a change on CMOS with micro-meter (pm) to nano-meter (nm) Scale. Even though there is a considerable enhancement in the network technologies there is no guarantee in the rate of Transmission and response times by the data Center [14]. [...]the edge devices continually utilizes the data from the cloud which forces the delivery data networks to decentralize the original data and service provisioning to the user a leveraging one.

The relation between high levels of psychosocial stress and the development of coronary artery disease (CAD) has been increasingly recognized, especially in women. We hypothesized that simple biomarkers of stress, urinary catecholamines/cortisol levels, are associated with more coronary artery calcium (CAC), an indicator of CAD, and that this relation is stronger in women compared with men. Using data from the Multi-Ethnic Study of Atherosclerosis Stress study, we examined the relation between urinary catecholamines/cortisol and CAC. The study cohort (n = 654) was 53% women, and 56.4% of the cohort had detectable CAC. Multivariable regression analyses assessed the relation between urinary catecholamines/cortisol and CAC (odds CAC >0 through logistic and ln CAC through Tobit model). There was an association between increased cortisol and increased CAC and an inverse association between dopamine and CAC. These relations were seen in men and women, with no difference between the genders. In conclusion, higher cortisol and lower dopamine levels are independently associated with higher CAC to a similar degree in men and women. These simple urinary biomarkers contribute to our understanding of the role of stress in the pathogenesis of CAD and may be incorporated into future strategies to prevent and treat CAD.

In this retrospective study we analyze and compare clinical characteristics and outcomes of patients with and without cancer history who were infected with novel coronavirus disease 19 (COVID-19). Medical records were reviewed and a comparative analysis of 53 cancer and 135 non-cancer patients with COVID-19 were summarized. Results: The median age for COVID-19 patients with and without cancer was 71.5 and 61.6 years, respectively. Patients aged 60 years and above were 86.8% and 60.7% in cancer and non-cancer groups, respectively. A high proportion of cases were seen in African Americans 73.6% (with cancer) and 75.6% (without cancer) followed by Hispanic patients. Male and female patients had a high percentage of prostate (39.3%) and breast (32%) cancer respectively. Prostate cancer (18.9%) and myeloma (11.3%) were common among solid and hematological cancers respectively. Hypertension and smoking were prevalent among cancer (83% and 41.5%) compared to non-cancer (67.4% and 9.6%) patients. The common symptoms in cancer patients were dyspnea (64.2%) followed by fever and cough (50.9%) compared to fever (68.1%) and cough (66.7%) in non-cancer patients. Cancer patients had higher levels of lactic acidosis, C-reactive protein, lactate dehydrogenase, and alkaline phosphatase than non-cancer patients (p < 0.05). Conclusions: Rapid clinical deterioration was seen in cancer patients who were aged 60 years and above. Higher mortality was seen in this subgroup, especially when they had associated hypertension and elevated levels of CRP and LDH.

High-density lipoprotein cholesterol (HDL-C) and apolipoprotein A-I (apoA-I) levels are inversely associated with adverse cardiovascular outcomes. Associations between these HDL-C–related measurements and coronary plaque progression have not been studied. We performed a retrospective analysis of 2,566 statin-treated patients with angiographic coronary artery disease who underwent serial evaluation of atheroma burden with intravascular ultrasound. Relations between achieved levels of HDL-related measurements with clinical characteristics and changes in plaque burden were determined. A strong correlation between HDL-C and apoA-I (r = 0.80, p <0.001) was observed. HDL-C, apoA-I, and the HDL-C:apoA-I ratio demonstrated negative correlations with the change in percent atheroma volume and total atheroma volume (all p ≤0.001). Increasing levels of achieved HDL-C:apoA-I (p = 0.04), but not HDL-C (p = 0.18) or apoA-I (p = 0.67), were associated with less progression of percent atheroma volume. Similar results were seen for change in total atheroma volume, with less progression seen with increased HDL-C:apoA-I (p = 0.002) but not with increases in HDL-C (p = 0.09) or apoA-I (p = 0.19). In conclusion, increasing levels of HDL-C:apoA-I associated with less progression of coronary atherosclerosis. This suggests that interventions increasing the cholesterol content of HDL particles may be of cardiovascular benefit.

Bupivacaine is an established and efficacious anesthetic that has become increasingly popular in postoperative pain management. However, there is limited literature regarding the potential for bupivacaine-induced delayed liver toxicity. Describe cholestasis as a potential adverse reaction of bupivacaine infusion into a surgical wound. Retrospective review of patients' medical records. We report the cases of 3 patients with new onset of cholestatic injury after receiving bupivacaine infusion for postoperative herniorrhaphy pain management. All patients had negative serologic workups for other causes of liver injury. All patients achieved eventual resolution of their liver injury. Bupivacaine-induced liver injury should be on the differential of individuals presenting with jaundice and cholestasis within a month of infusion via a surgically placed catheter of this commonly used anesthetic. •Bupivacaine is being increasingly used as an anesthetic.•Bupivacaine use can result in liver injury.•Most patients with bupivacaine-induced liver injury have complete recovery of their liver function with supportive treatment.

Pancreatic ductal adenocarcinoma, an extremely aggressive cancer, has high metastatic potential. Cutaneous metastasis is very uncommon, representing only <10% of all cases, presenting mostly around the umbilical region. Non-umbilical metastasis is even rarer, and the significance remains unknown. In this article, we describe a case of a 76-year-old gentleman who initially presented with an asymptomatic scalp lesion, which on biopsy revealed metastatic adenocarcinoma of pancreatic origin. Detailed workup revealed extremely high tumor burden with metastases involving muscles, subcutaneous tissues, bone, lung, spleen, liver, and colon. Cutaneous involvement in pancreatic cancer represents poor survival with widespread dissemination of the disease. The involvement of some sites and not others and the extreme degree of aggressiveness might reflect subgroups of this cancer with different molecular biology. Identifying these groups may have utility in determining prognosis and stratifying treatment for patients. This will hopefully translate into better diagnostic tests and therapies in the near future.
