The Relationship

Stress researchers have emphasized the relationship between social stress and mental health. However, research investigating police brutality as a stressor is scarce. The authors conceptualize police brutality as a stressor, examining racial variation in its effects on mental health. Data came from the Survey of the Health of Urban Residents in the United States ( n = 4,389). Negative encounters with the police were found to be associated with depressed mood and anxiety. The relationship between encounters with the police and depressed mood was stronger among Black respondents and Latinxs compared with Whites. Regardless of personal encounters with the police, the anticipatory stress of police brutality—concern that one might become a victim of police brutality—was associated with depression and anxiety. These findings highlight police brutality as an anticipatory stressor and have implications for whiteness as a resource that protects from the stress of negative police encounters.

The Relationship

The relationship between ciliary neurotrophic factor (CNTF) genotype and muscle strength was examined in 494 healthy men and women across the entire adult age span (20–90 yr). Concentric (Con) and eccentric (Ecc) peak torque were assessed using a Kin-Com isokinetic dynamometer for the knee extensors (KE) and knee flexors (KF) at slow (0.52 rad/s) and faster (3.14 rad/s) velocities. The results were covaried for age, gender, and body mass or fat-free mass (FFM). Individuals heterozygous for the CNTF null (A allele) mutation (G/A) exhibited significantly higher Con peak torque of the KE and KF at 3.14 rad/s than G/G homozygotes when age, gender, and body mass were covaried ( P < 0.05). When the dominant leg FFM (estimated muscle mass) was used in place of body mass as a covariate, Con peak torque of the KE at 3.14 rad/s was also significantly greater in the G/A individuals ( P < 0.05). In addition, muscle quality of the KE (peak torque at 3.14 rad · s−1 · leg muscle mass−1) was significantly greater in the G/A heterozygotes ( P < 0.05). Similar results were seen in a subanalysis of subjects 60 yr and older, as well as in Caucasian subjects. In contrast, A/A homozygotes demonstrated significantly lower Ecc peak torque at 0.52 rad/s for both KE and KF compared with G/G and G/A groups ( P < 0.05). No significant relationships were observed at 0.52 rad/s between genotype and Con peak torque. These data indicate that individuals exhibiting the G/A genotype possess significantly greater muscular strength and muscle quality at relatively fast contraction speeds than do G/G individuals. Because of high positive correlations between fast-velocity peak torque and muscular power, these findings suggest that further investigations should address the relationship between CNTF genotype and muscular power.

Mood Induction Procedure

The relationship between depressed mood, reasoning and perceptual performance was examined with 57 undergraduate volunteers. To intensify its effect, Velten's 1968 mood induction procedure was modified by having subjects hear a prerecording of each mood statement prior to saying it themselves. Also, midway through the experiment subjects completed an abbreviated mood induction to ensure continuation of the appropriate mood. Ratings of subjects' mood on a 13-point Likert scale before and after mood induction indicated the mood induction was effective. Subjects completed the reasoning measure of 48 syllogisms, and the perceptual measure involving identification of positive, negative, or neutral stimulus words presented tachistoscopically. “Depressed” individuals showed poorer reasoning performance of marginal significance than “elated” subjects. Mood induction did not appear to affect perceptual performance. Results are discussed in terms of the research on reasoning deficits in depression.

Purpose To evaluate the feasibility of using skeletal muscle mass (SMM) at C3 (C3 SMM) as a diagnostic marker for sarcopenia in head and neck cancer (HNC) patients. Methods We evaluated 165 HNC patients and 42 healthy adults who underwent 18F-fluorodeoxyglucose positron emission tomography/computed tomography scans. The paravertebral muscle area at C3 and skeletal muscle area at L3 were measured by CT. Pearson’s correlation was used to assess the relationship between L3 and C3 SMMs. The prediction model for L3 SMM was developed by multiple linear regression. Then the correlation and the agreement between actual and predicted L3 SMMs were assessed. To evaluate the diagnostic value of C3 SMM for sarcopenia, the receiver operating characteristics (ROC) curves were analyzed. Results Of the 165 HNC patients, 61 (37.0%) were sarcopenic and 104 (63.0%) were non-sarcopenic. A very strong correlation was found between L3 SMM and C3 SMM in both healthy adults (r = 0.864) and non-sarcopenic patients (r = 0.876), while a fair association was found in sarcopenic patients (r = 0.381). Prediction model showed a very strong correlation between actual SMM and predicted L3 SMM in both non-sarcopenic patients and healthy adults (r > 0.9), whereas the relationship was moderate in sarcopenic patients (r = 0.7633). The agreement between two measurements was good for healthy subjects and non-sarcopenic patients, while it was poor for sarcopenic patients. On ROC analysis, predicted L3 SMM showed poor diagnostic accuracy for sarcopenia. Conclusions A correlation between L3 and C3 SMMs was weak in sarcopenic patients. A prediction model also showed a poor diagnostic accuracy. Therefore, C3 SMM may not be a strong predictor for L3 SMM in sarcopenic patients with HNC.

Whilst there is a considerable literature surrounding predictors of depressed mood in stroke survivors, much less research has been directed towards identifying the impact of a stroke on primary informal carers and the nature of the relationship between patient and carer characteristics, stroke consequences and carer distress. This review attempts to elucidate such relationships so that implications for health and social care provision can be drawn.

Background It is known that sarcopenia is related to malnutrition-inflammation-atherosclerosis (MIA) syndrome and is an important problem in dialysis patients. The notion of frailty includes various physical, psychological, and social aspects. Although it has been reported that sarcopenia is associated with poor prognosis in patients with hemodialysis, reports on peritoneal dialysis (PD) patients are rare. In this study, we examined the morbidity and mortality of sarcopenia and frailty in PD patients. We also investigated the MIA-related factors. Methods We evaluated 119 patients cross-sectionally and longitudinally. The Asian Working Group for Sarcopenia criteria and the Clinical Frailty Scale (CFS) were used to diagnose sarcopenia and frailty. The primary outcome is all-cause mortality with sarcopenia and frailty. The secondary outcome is the relationship between various MIA-related factors. Results Morbidity of sarcopenia and frailty in PD patients was 8.4% and 10.9%, respectively. Old age, high values of Barthel Index, Charlson Comorbidity Index, CFS, and low values of body mass index (BMI), muscle strength, muscle mass, and slow walking were associated with sarcopenia. Interleukin-6, albumin, and prealbumin were significantly correlated with muscle mass. During follow-up, the presence of sarcopenia or frailty was associated with the risk of mortality. In multivariate analysis, CFS was related to the mortality rate of PD patients. Conclusions The presence of sarcopenia or frailty was associated with a worse prognosis.

Rate of body weight gain of both the young chick and the young rat was markedly inhibited following ingestion of amounts of thyroxine which were greatly in excess of physiological requirements. The rate of body weight gain of the young rat was also markedly inhibited in alloxan diabetes. The administration of insulin partly or largely prevented the observed effect on body weight in both conditions. The administration of thyroxine caused a reduction of rat skeletal muscle mass which was partially prevented when insulin was given concurrently with thyroxine.Reduced body weight gain and muscle mass in the rat were accompanied by marked increases in the muscle DNA and nuclei concentration. Nuclear diameter and the amount of DNA per nucleus remained unchanged. RNA concentration of the muscle was not reduced. The beneficial effect of insulin administration on body weight and muscle mass was accompanied by a preventive effect against changes in muscle DNA and nuclei concentration. However, since the DNA content of muscle bundles remained relatively unchanged and since muscle bundle weights changed proportionately with body weight it would appear that DNA content does not reflect change in muscle mass.The effectiveness of insulin in the thyroxine-treated animal appears to be due to an improved utilization of energy. A hypoglycemic action of thyroxine implies an antagonism between the two hormones in their mechanism of action. The relationship between the two hormones is not direct since the administration of insulin does not affect the increased plasma protein-bound iodine levels resulting from thyroxine treatment.
