Clinical presentation,viral kinetics,and management of human monkeypox cases from New Delhi,India 2022

We describe the clinical and demographic characteristics, virological follow-up, and management of five confirmed monkeypox cases from New Delhi, India without any international travel history. The viral load kinetics and viral clearance were estimated in oropharyngeal swabs (OPS), nasopharyngeal swabs (NPS), EDTA blood, serum, urine, and various lesion specimens on every fourth day of follow-up ranging from 5 to 24 post onset day (POD) of illness. All five cases presented with mild to moderate-grade intermittent fever, myalgia, and lesions on the genitals, groins, lower limb, trunk, and upper limb. Four cases had non-tender firm lymphadenopathy. No secondary complications or sexually transmitted infections were recorded in these cases except for the presence of viral hepatitis B infection marker hepatitis B virus surface antigen (HBsAg) in one case. All the cases were mild and had a good recovery. A higher viral load was detected in lesion fluid (POD 9), followed by lesion roof (POD 9), urine (POD 5), lesion base (POD 5), and OPS/NPS (POD 5). The monkeypox virus (MPXV) DNA was detected in clinical samples from 5th to 24th POD. These monkeypox cases without international travel history suggest the underdiagnosed monkeypox infection in the community. This emphasizes the need for active surveillance of MPXV in the high-risk population such as men having sex with men and female sex workers.     

Engagement with arts and culture activities in the Danish general population: Longitudinal associations with new onset or persistent depression and mental wellbeing

Objectives

International literature suggests that arts and culture activities may benefit mental health, however, such survey studies conducted in the Danish population are scarce. Further, studies have investigated the associated risk for incident depression, but not for persistent depression. The objective of the current prospective study was to assess associations of engagement in arts and culture activities with incident/persistent depression and also mental wellbeing among Danish adults in the general population.

Design

Observational prospective study.

Methods

Data stem from a Danish nationally representative panel study of 5000 adults (aged 15+ years) conducted in 2019 and 2020, which was linked to Danish register data. An exposure variable was constructed for frequency of attending concerts, theatres, museums, and cinemas. Validated scales were used to assess the presence of depression (PHQ-8) and levels of mental wellbeing (SWEMWBS). Binary logistic regression analyses were conducted to assess the risk of incident depression (among participants free of depression at baseline), as well as the risk of persistent depression (among participants with depression at baseline), while multinomial logistic regression was used to assess odds for moderate and high mental wellbeing (low as base outcome) while adjusting for baseline values.

Result

In terms of incident depression, quarterly engagement in arts and culture activities (compared to never) was associated with an OR of .43 (95%CI .23–.80), while 8 times or more was associated with an OR of .53 (.29–.97). In terms of persistent depression, quarterly engagement was associated with an OR of .30 (.10–.90), while 8 times per year or more was associated with an OR of .26 (.07–.92). Similar to the patterns for incident/persistent depression, associations with moderate mental wellbeing showed higher odds for quarterly engagement and 8 times per year or more. Quarterly engagement was also associated with higher odds for high mental wellbeing but did not reach statistical significance.

Conclusions

The results support the involvement of the cultural and creative sectors in health strategies. Mental health promotion initiatives as well as arts and culture sectors may encourage the general public to engage in arts and culture activities with frequencies of at least once per quarter.     

Study of congenital duodenal obstruction

A study of 23 neonates with congenital duodenal obstruction is reported. Their mean gestational age was 38 weeks and mean weight was 2.2 kg. Main clinical features observed were vomiting (100%), which was bilious in 74%, and epigastric fullness with visible peristalsis (74%). Plain X-ray abdomen confirmed the diagnosis in 78%. Associated congenital malformations were seen in 39% of cases. Eleven babies had an intrinsic defect, 11 had extrinsic defect and one baby had combination of intrinsic and extrinsic defect. Malrotations along with band was seen in 39% of cases. Reported mortality was 39%.     

Pharmacokinetics of Nisoldipine Coat--Core Formulation in Subjects with Liver Cirrhosis

The pharmacokinetics of a controlled-release formulation (coat--core) of the calcium channel blocker nisoldipine was investigated in eight subjects with biopsy-proved liver cirrhosis and eight healthy subjects. In Stage I, subjects received a single 10-mg dose to determine if this dose would be safely tolerated in the subjects with cirrhosis. Because all subjects in both groups tolerated the dose without difficulty, all were continued to Stage II. In Stage II, subjects received a once-daily dose of 10-mg coat-core tablets for 7 days. Serial plasma samples were assayed for nisoldipine in both stages. The C(max) and AUC of nisoldipine were approximately fourfold to fivefold higher (p < 0.01) in subjects with cirrhosis as compared to healthy subjects; however, there was overlap in the range of pharmacokinetic parameters between the two groups. The accumulation factor following multiple dosing was similar in both groups. Results suggest that nisoldipine dose should be optimized by monitoring of a pharmacodynamic end point, such as effect on blood pressure. It is likely that dose requirements for patients with liver disease will be lower.     

The Effect of Basic Fibroblast Growth Factor on the Reversion of Omental Adipocytes from Lean and Obese Patients

Background: this study was designed to characterize some of the biochemical and molecular genetic changes during reversion of human fat cells. Methods: mature adipocytes were isolated from greater omental fat tissue of eight lean and 14 massively obese persons by established methodology. Results: at day 7 of adherence to Leighton tubes, there was appreciable depletion of triacylglycerol, as well as assumption of an elongated contour. Relatedly, there was an increase in the expression of β-actin mRNA and a significant decrease in the specific activity of cytosolic glycerophosphate dehydrogenase. The decrement in the specific activity of glycerophosphate dehydrogenase, after 7 days in culture, was significant at p < 0.001. Basic fibroblast growth factor at 10 ngml^-1 accelerated significantly (p < 0.03) the decrease in the specific activity of glycerophosphate dehydrogenase in adipose cells from lean subjects. In contrast, basic fibroblast growth factor had no significant influence on cells from massively obese persons. Conclusion: such resistance may contribute to the intractability of massive obesity.     

Factors involved in the differential response to ethanol,barbital and pentobarbital in rats selectively bred for ethanol sensitivity

Two lines of rats, least affected (LA) and most affected (MA), had been selectively bred for their differential sensitivity to ethanol. Both males and females of the LA strain were observed to be less sensitive than their MA counterparts to the acute hypnotic and motor-impairing effects of ethanol. However, a lower ethanol metabolic rate of the MA males suggests that both CNS and metabolic factors contribute to their enhanced sensitivity to ethanol. By contrast, no differences were observed between the LA and MA males with respect to the hypnotic and subhypnotic effects of pentobarbital or to the clearance of this drug. MA females were more sensitive only to the hypnotic effects of pentobarbital, probably because of a smaller apparent volume of distribution. No strain difference was observed in the hypnotic effect or clearance of barbital. These observations suggest that, in spite of a differential sensitivity to ethanol, the LA and MA lines do not differ in their response to the barbiturates tested.     

Physical growth of primary school children of Lucknow

Conclusion From the above consideration we conclude that the stature of the boys and girls in all the age groups grew more rapidly than the other body segments under consideration. On the other hand, the arm girth grew very slowly. The mean values were progressively higher while the rate of growth and growth velocities were different in different age groups. The mean values of the lower extremity and biacromial indices were nearly constant in all the age groups which showed relatively equal growth of the stature in relation to lower extremity and shoulder breadth.

The conduct of in vitro and in vivo drug-drug interaction studies: a Pharmaceutical Research and Manufacturers of America (PhRMA) perspective.

Current regulatory guidances do not address specific study designs for in vitro and in vivo drug-drug interaction studies. There is a common desire by regulatory authorities and by industry sponsors to harmonize approaches, to allow for a better assessment of the significance of findings across different studies and drugs. There is also a growing consensus for the standardization of cytochrome P450 (P450) probe substrates, inhibitors and inducers and for the development of classification systems to improve the communication of risk to health care providers and to patients. While existing guidances cover mainly P450-mediated drug interactions, the importance of other mechanisms, such as transporters, has been recognized more recently, and should also be addressed. This article was prepared by the Pharmaceutical Research and Manufacturers of America (PhRMA) Drug Metabolism and Clinical Pharmacology Technical Working Groups and represents the current industry position. The intent is to define a minimal best practice for in vitro and in vivo pharmacokinetic drug-drug interaction studies targeted to development (not discovery support) and to define a data package that can be expected by regulatory agencies in compound registration dossiers.
