The research reported in this paper is the second of a two phase study related to consumer packaging. In the first phase, the subjects consisted of 100 elderly males and 100 elderly females. The results of this phase of the study were reported at the 1983 HFS meeting in Norfolk. In this phase of the study, the subjects were 100 four-year old boys and 100 four-year old girls. The purpose of the study was to measure their wrist-twisting strength or the torque that could be exerted on jar lids of various diameters. To accomplish this, a standard torque-wrench was modified so as to accept eight container lids whose diameters ranged from 27 mm to 123 mm. Each subject performed the wrist-twisting task on each lid four times - twice clockwise and twice counter-clockwise. Using torque as the dependent measure, analyses of variance were computed for the boys and girls separately. The results showed that direction of rotation - clockwise or counterclockwise, was not significant. However, lid as a source of variation was. When age, body weight, height, grasp, lateral prehension, and hand length, breadth, and spread were correlated with the wrist-twisting strength, it was found that for the boys, grasp was critical for all eight of the lids and hand length and spread were equally important. For the females, the individual's body weight plus grasp were significantly correlated with torque for all eight lids. And whereas age and weight were significantly correlated with the torque that could be exerted on seven of the eight lids for the girls, they were only modestly related to torque for the males. However, like the boys, hand spread was significantly correlated with torque among the females. Findings related to reports of the Consumer Products Safety Commission and the Safety in Packaging Act are discussed and a proposal is advanced suggesting that the use of containers whose lids have diameters of 60 mm and larger would be too large for a four-year old hand to open while they could be readily opened by the elderly consumer.*

The purpose of this study was to measure the wrist-twisting strength among the elderly. The subjects were 100 men and 100 women whose ages ranged from 62 to 92 years. To measure their wrist-twisting strength a device was developed that consisted of a modified torque-wrench which would accept 8 different container lids whose diameters ranged from 27 mm to 123 mm. Each subject performed the wrist-twisting task on each lid 4 times – twice clockwise and twice counter-clockwise. The results showed that men were stronger than the women, that there was no difference in the torque from a clockwise or a counter-clockwise twist, and that a greater amount of torque could be applied to large diameter lids than to smaller diameter lids. When age, body weight, height, grasp, lateral prehension, and hand length, breadth, and spread were correlated with the wrist-twisting strength it was found that for the men, age, grasp and hand length contributed to torque and for the women, body weight, grasp, and lateral prehension were the main determinants of torque. In addition the torque required to open various commercial products was measured so that by comparing these torque values with those of the wrist-twisting strength it was able to estimate the percentage of men and women who could open a jar of a given diameter and torque.

Abstract Better understanding of the lead curvature, movement and their spatial distribution may be beneficial in developing lead testing methods, guiding implantations and improving life expectancy of implanted leads. Objective The aim of this two-phase study was to develop and test a novel biplane cine-fluoroscopy-based method to evaluate input parameters for bending stress in leads based on their in vivo 3D motion using precisely determined spatial distributions of lead curvatures. Potential tensile, compressive or torque forces were not subjects of this study. Methods A method to measure lead curvature and curvature evolution was initially tested in a phantom study. In the second phase using this model 51 patients with implanted ICD leads were included. A biplane cine-fluoroscopy recording of the intracardiac region of the lead was performed. The lead centerline and its motion were reconstructed in 3D and used to define lead curvature and curvature changes. The maximum absolute curvature Cmax during a cardiac cycle, the maximum curvature amplitude Camp and the maximum curvature Cmax@amp at the location of Camp were calculated. These parameters can be used to characterize fatigue stress in a lead under cyclical bending. Results The medians of Camp and Cmax@amp were 0.18 cm−1 and 0.42 cm−1, respectively. The median location of Cmax was in the atrium whereas the median location of Camp occurred close to where the transit through the tricuspid valve can be assumed. Increased curvatures were found for higher slack grades. Conclusion Our results suggest that reconstruction of 3D ICD lead motion is feasible using biplane cine-fluoroscopy. Lead curvatures can be computed with high accuracy and the results can be implemented to improve lead design and testing.

Background: Nutrition plays an important role in maintaining the overall health of older people. Inadequate intake may lead to impaired body function, higher morbidity, and mortality. Oral nutritional supplements (ONS) showed positive effect on the nutritional status of the elderly; however, systematic evidence is currently lacking on the effect of ONS on the elderly with anorexia. Aims: The current systematic review and meta-analysis included randomized controlled trial (RCT) articles to investigate the effectiveness of ONS on the main aspects of anorexia of aging (AA). Methods: By using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) method, researchers independently searched PubMed/MEDLINE, EMBASE, CINAHL, PsycINFO, the Cochrane Library, China National Knowledge Infrastructure (CNKI) and other gray literature resources for publications that met the inclusion criteria by October 2020. The Cochrane Risk of Bias Tools were used for quality assessment. The inverse-variance method was used for the fixed model (FM) while the DerSimonian–Laird method was used for the random model (RM). Respective 95% confidence intervals (95% CIs), mean difference (MD) or standardized mean difference (SMD) was used for indices in terms of effect size (ES). Results: 2497 records were found through the systematic search, while 17 RCTs (n = 1204) were included, with a mean age of 81.9 years (range: 74–87 years). Supplementation occurred in the morning, mid-day, and evening, while the times varied from one to three times a day. The results of meta-analysis showed that, generally, ONS had a positive effect on the overall appetite, MD = 0.18, 95% CI (0.03, 0.33), p = 0.02, and consumption, MD = 1.43, 95% CI (0.01, 2.86), p = 0.05; but not significant in terms of other aspects of appetite: hunger, p = 0.73; fullness, p = 0.60; desire to eat, p = 0.80; preoccupation, p = 0.15. Additionally, it showed an increase in the overall energy intake, SMD = 0.46, 95% CI (0.29, 0.63), p < 0.001, in protein intake, SMD = 0.59, 95% CI (0.16, 1.02), p = 0.007, and in fat intake, MD = 3.47, 95% CI (1.98, 4.97), p < 0.001, while no positive effect was found on carbohydrates intake, p = 0.06. Significance differences were also found in the body weight, SMD = 0.53, 95% CI (0.41, 0.65), p < 0.001, and body mass index (BMI), MD = 0.53, 95% CI (0.12, 0.95), p = 0.01. Moreover, subgroup analyses were conducted according to the nutrient density with no positive results showed except for the low-density ONS on overall energy intake. Conclusions: The results of the present study indicated that ONS had beneficial effects on overall appetite, energy intake, body weight and BMI.

Objective: The cytomorphological criteria of malignant endometrial lesions in cervical samples are less well described than those of cervical lesions. We wished to investigate if there were features in SurePath™ liquid-based cytology samples that would facilitate more accurate differentiation between benign and malignant endometrial cells. Study Design: This was a two-phase study, with a review of all SurePath™ samples reported as endometrial adenocarcinoma (n = 42) evaluating 12 cytological features in the first phase. In phase 2 (test set), all initial cases plus an additional 83 cases were reviewed using these 12 cytological features to predict the outcome. Results: Out of 12 cytological features evaluated in phase 1 (training set), nuclear chromatin pattern, apoptotic bodies and tingible body macrophages were found to be the most significant features determining malignant histological outcome. These 12 cytological features were re-evaluated in phase 2 (n = 125). Of 125 cases, 54 had a benign and 71 had a malignant or premalignant histological outcome, with a positive predictive value of 56.8%. Conclusion: Granular nuclear chromatin, tingible body macrophages and apoptosis in the background are the most significant factors in determining whether endometrial cells present in cervical samples represent malignancy or are benign. Using these features, relatively accurate predictions of endometrial pathology can be made.

Abstract Background: The detection of a pathogenic variant in the BRCA1 or BRCA2 gene has medical and psychological consequences for both, affected mutation carriers and their relatives. This study analyzed the psychological impact of genetic testing and mutation-positive test result as well as associated family communication processes from the perspective of BRCA1 or BRCA2 mutation carriers and their family members.Methods: We conducted a two-phase study with explanatory sequential mixed methods design to understand the perspective of psychological process regarding genetic testing more efficiently. First, we analyzed a survey data of 79 carriers of a BRCA1 or BRCA2 mutation. Second, we conducted focus group interviews of 10 family members to deepen understanding of communication processes in high-risk families.Results: The average age of the BRCA1 or BRCA2 mutation carriers was 48 years, 58% had a history of cancer. The majority (64.6%) had general psychological distress independent of cancer diagnosis in the patients’ history. The point prevalence of depression was 16.9%. The main motives for undergoing genetic testing were desire for safety, prevention and risk assessment for the own children. The mutation carriers were satisfied with the decision to undergo genetic testing. Contrary to their subjective perception, the respondents' knowledge about those mutations was moderate. The familial communication was merely partially successful. In contrast to the high rate of disclosure to at-risk relatives (100%), the reported uptake of genetic testing among informed at-risk relatives was low (45.6%). In-depth focus group interviews with 10 family members revealed significant barriers to accessing genetic counseling including anxiety, uncertainty about the benefits of testing and the own cancer risk, particulary among males.Conclusion: The detection of a BRCA1 or BRCA2 mutation has psychological impact not only on mutation carriers but also on their family members. An adequate knowledge of the genetic background is required to reduce the level of psychological distress and to support the familial communication process. Therefore, the quality of information sources for affected individuals and relatives and also the awareness of health care professionals have to be improved.

Schizophrenia is a devastating and highly disabling disorder associated with long-term consequences. Treatment is often made difficult by the presence of comorbidities like depression which when considered in management ensures good outcome. This study aimed to determine the prevalence and correlates of depression in schizophrenia. It is a two-phase study involving 320 outpatients recruited by consecutive sampling. The first phase entails confirming diagnosis with Mini International Neuropsychiatric Interview (MINI), psychotic disorder module, assessing socio-demographic characteristic and screening for depressive symptoms with the Beck Depression Inventory (BDI) by a trained assistant. In the second phase, the researcher then assesses for depressive disorder using MINI, depressive disorder module among subjects who screened positive with BDI together with 10% of those who screened negative. Over four-fifth (83.4%) of the participants were less than 50 years, they were mostly females (57.2%), of Yoruba ethnic group (59.7%), Christians (75.6%), and earn below ₦18,000 monthly or nothing (72.2%). Also, a large proportion (86.2%) had good social support. Over a third of the participants were married (38.1%) with about four-fifth of these living with their spouses. The prevalence of depressive symptoms and depressive disorder were 49.7% and 38.4% respectively. Logistic regression revealed that poor social support predicts depressive in Schizophrenia. In conclusion, Depression is common in patients with schizophrenia. Therefore, thorough evaluation of schizophrenic patients is necessary so that, co-morbid depression when present can be detected and considered in management to ensure good treatment outcome.
