Impact of COVID‐19 on wound care in Germany

Recent studies showed that the COVID‐19 pandemic caused collateral damage in health care in terms of reduced hospital submissions or postponed treatment of other acute or chronic ill patients. An anonymous survey was sent out by mail to patients with chronic wounds in order to evaluate the impact of the pandemic on wound care. Sixty‐three patients returned the survey. In 14%, diagnostic workup or hospitalisation was cancelled or postponed. Thirty‐six percent could not seek consultation by their primary care physician as usual. The use of public transport or long travel time was not related to limited access to medical service (P = .583). In ambulatory care, there was neither a significant difference in the frequency of changing wound dressings (P = .67), nor in the person, who performed wound care (P = .39). There were no significant changes in wound‐specific quality of life (P = .505). No patient used telemedicine in order to avoid face‐to‐face contact or anticipate to pandemic‐related restrictions. The COVID‐19 pandemic impaired access to clinical management of chronic wounds in Germany. It had no significant impact on ambulatory care or wound‐related quality of life. Telemedicine still plays a negligible role in wound care.     

Fertility and digital technology: narratives of using smartphone app ‘Natural Cycles’ while trying to conceive

Fertility awareness apps, which help to identify the ‘fertile window’ when conception is most likely, have been hailed as ‘revolutionising’ women’s reproductive health. Despite rapidly growing popularity, little research has explored how people use these apps when trying to conceive and what these apps mean to them. We draw on in‐depth, qualitative interviews, adopting a critical digital health studies lens (a sub‐field of science and technology studies), to explore the experiences of cisgender women and partners with one such app, Natural Cycles, in the context of their daily lives. We found that many women valued the technology as a ‘natural’, inobtrusive alternative to biomedical intervention, and a means of controlling and knowing their bodies, amid a dearth of fertility‐related education and care. Yet this technology also intervened materially and affectively into the spaces of their lives and relationships and privileged disembodied metrics (temperature) over embodied knowledge. Meanwhile, app language, advertising and cost have contributed to characterising ‘typical’ users as white, heterosexual, affluent, cisgender women without disabilities. In the context of neoliberal shifts towards bodily self‐tracking, technologies appealing as novel, liberating and ‘natural’ to individuals who can access them may nevertheless reproduce highly gendered reproductive responsibilities, anxieties and broader health and social inequalities.

Dietary and physical activity correlates of long-term weight loss

Covariations in body mass index (BMI), physical activity, macronutrient intake, and the frequency of consumption of specific foods were examined among 82 men and 75 women participating in a behavioral weight loss program over a period of 18 months. Results of repeated measures analyses of covariance showed that BMI change was inversely related to change in physical activity and change in frequency of vegetable consumption. BMI change was positively related to change in calorie intake from fat and change in frequency of consumption of beef, hot dogs, and sweets. Change in fat calories predicted BMI change better than change in total calories. In addition, change in the frequency of consumption of specific foods accounted for a larger percentage of the variance in BMI change than did change in macronutrients (10.4% vs. 5.2%). No differences were found between predictors of weight loss vs. weight maintenance.     

A comparison of the reinforcing efficacy of PCP, the PCP derivatives TCP and BTCP, and cocaine using a progressive ratio schedule in the rat

This study was designed to compare the reinforcing efficacy of PCP (phencyclidine:phenylcyclohexyl-piperidine) and the PCP-derivatives BTCP (N-[1-(2-benzo(b)thiophenyl) cyclohexyl]piperidine) and TCP (N-[1-(2-thienyl)cyclohexyl]-piperidine) to that of cocaine, using a progressive ratio schedule of reinforcement (PR). On the PR schedule the number of responses required to obtain an i.v. infusion of drug was escalated with each injection until a breaking point was reached when the animal stopped responding. Since BTCP has an affinity for the DA uptake site comparable to that of cocaine, it was hypothesized that BTCP and cocaine would show similar patterns of self-administration and comparable breaking points. In contrast, the high affinity of TCP and PCP for the NMDA-ion channel complex suggested that these two compounds would also support comparable self-administration behaviors. Rats were trained to self-administer i.v. cocaine during daily 5h sessions under a fixed-ratio-1 (FR1) schedule. Once consistent lever-pressing behavior was established, BTCP, PCP or TCP was substituted for cocaine. Under the FRI schedule, BTCP elicited a regular pattern of lever pressing, unlike PCP and TCP. However, under the PR schedule BTCP elicited breaking points comparable to those produced by equivalent doses of cocaine, whereas TCP and PCP produced considerably lower breaking points. These results suggest that BTCP has comparable rewarding properties to that of cocaine, and that like those of cocaine they are most probably mediated through a site of action at the DA transporter. In contrast, the relatively weak reinforcing efficacy of PCP and TCP would correlate better with their primary site of action on the PCP binding site within the NMDA-ion channel complex.     

Is moderate alcohol use related to wages? Evidence from four worksites

Moderate alcohol users (approximately two drinks per day on average) have recently been shown to have a lower risk of coronary heart disease relative to abstainers and heavy drinkers. Conversely, a few studies have found that alcoholism is associated with greater unemployment and lower earnings. But, little research has examined the differential effects of drinking levels on job compensation. We utilize a newly created database on employees at four worksites to test for a nonlinear relationship between alcohol use and wages. We also examine whether alcohol use affects wages indirectly through educational achievement, marital status, and poor health. Our findings suggest an inverse U-shaped relationship between alcohol consumption and wages with a peak at approximately 1.5 to 2.5 drinks per day on average. Thus, controlling for other variables and conditional on working, moderate alcohol users have higher wages than abstainers and heavy drinkers at these worksites. We also find evidence that alcohol use is related to wages through human capital variables.     

Trichomonas vaginalis: diagnosis and clinical characteristics in pregnancy

Objective: The objectives of this study were to 1) determine the prevalance and characterize the symptomatology of Trichomonas vaginalis (TV) infection in pregnant women on entry into prenatal care in an inner-city population; 2) compare conventional microscopic methods vs. culture techniques in diagnosing TV in both symptomatic and asymptomatic pregnant patients; and 3) correlate wet mount microscopic and microbiologic characteristics of varying manifestations of trichomoniasis.Methods: One thousand two hundred sixty patients in an inner-city population were tested at entry into prenatal care for TV by saline wet mount and culture techniques. Other tests for lower genital tract infection were also performed. Vaginal symptoms were ascertained through standardized questioning prior to examination. Standard microscopic and microbiologic data were also obtained for analysis. Wet mounts were systematically examined and considered negative if no TV was identified in 10 high powerfields (HPFs). Cultures were inspected from days 4 to 7 or until positive results were obtained. Results were analyzed using McNemar's test for correlated proportions, chi-squared test, or Fisher exact test where appropriate.Results: Culture and wet mount results were available in 1,175 patients. TV infection was documented by one or both techniques in 110/1,175 (9.4%). Culture methods detected 105/110 (94.5%) of all patients while wet mount detected 90/110 (73%) (P <0.001). Vaginal symptoms were present in only 20/110 patents (18.2%). Among asymptomatic patients, culture detected 94% while wet mount detected 70% (P < 0.001). Among symptomatic patients, wet mount and culture were both effective and diagnosed 85% and 95% of infections, respectively (P = not significant). Patients with TV were more likely to have increased vaginal fluid wlaite blood cells (WBCs) and more severe vaginal flora disruption than uninfected controls. Subgroup analysis revealed wet mount-positive/culture-positive patients were more likely to have vaginal flora disruption, as evidenced by decreased lactobacilli and elevated vaginal pH, than wet mount-negative/culture-positive subjects. Coexistent infection rates were similar regardless of wet mount status. Elevated vaginal fluid WBCs were more common among patients with symptoms.Conclusions: 1) Screening pregnant women for TV based solely on symptomatology is ineffective in this population; 2) culture techniques detected more infections than conventional microscopic evaluation; and 3) significant increases in vaginal fluid WBCs and altered vaginal flora are found in both symptomatic and asymptomatic TV, suggesting that both infestations have the potential to adversely affect pregnancy outcome. Studies on the influence of TV on pregnancy outcomes are ongoing.     

Mistreatment due to weight: prevalence and sources of perceived mistreatment in women and men

OBJECTIVE: Previous research has documented prejudicial attitudes and discrimination against overweight people. Yet the extent to which overweight people themselves perceive that they have been mistreated because of their weight has not been carefully studied. The purpose of this study was to examine the prevalence of perceived mistreatment due to weight and sources of perceived mistreatment. METHODS AND PROCEDURES: A non-clinical sample of healthy adults (187 men and 800 women) enrolled in a weight gain prevention program comprised the study population. A self-administered questionnaire was used to measure perceived mistreatment due to weight. RESULTS: Overall, 22% of women and 17% of men reported weight-related mistreatment. The most commonly reported sources of mistreatment among women were strangers (12.5%) and a spouse or loved one (11.9%). Men were most likely to report mistreatment by a spouse or loved one (10.2%) and friends (7.5%). Somewhat surprisingly, sex differences in perceived weight-related mistreatment were significant only for stranger as the source. Perceived weight-related mistreatment was positively associated with body mass index (BMI) (r = 0.39, p<0.0001). Reported mistreatment was nearly ten times as pervalent among individuals in the highest quartile of the BMI distribution (42.5%) than among those in the lowest BMI quartile (5.7%), but was significantly greater than zero in all but the very lean. DISCUSSION: Perceived mistreatment due to weight is a common experience and is not restricted to the morbidly obese. Results are discussed in light of the sociocultural value for thinness.
