Schäfer D. Are Old Men Impotent? On a Sparse Discourse of Early Modern Medicine and Its Forensic Implications in Paolo Zacchia's Quaestiones medico-legales. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:16513. [PMID: 36554393 PMCID: PMC9779390 DOI: 10.3390/ijerph192416513] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/24/2022] [Revised: 12/06/2022] [Accepted: 12/06/2022] [Indexed: 06/17/2023]
Abstract
In early modern medical literature, there are increasing references to sterility and impotence in older men. This is especially true of the Quaestiones medico-legales by the Roman physician Paolo Zacchia (1584-1659). In several books of this systematically structured manual, its author discusses medical and legal arguments on the one hand. On the other hand, in the 10th, only posthumously published volume, a total of five cases of impotence in old men are described on the basis of court decisions of the Rota Romana and expert opinions of the author. The paper examines these cases with regard to central statements on male impotence in old age, which are placed in the medical as well as the social and legal-historical context of the time. It becomes clear that old-age impotence and sterility were less a medical than a legal problem in the 17th century. However, the physician Zacchia emphasises the concept of biological age instead of historically transmitted numerical age limits. In this respect, his expert opinions already show the first signs of medical empiricism.

Plümecke T, Mikosch H, Mohrenberg S, Supik L, Bartram I, Ellebrecht N, zur Nieden A, Schnieder L, Schönberger H, Schulze-Marmeling C, Gutzeit A. Differences in mortality in Switzerland by citizenship during the first and second COVID-19 waves: Analysis of death statistics. Front Public Health 2022; 10:992122. [PMID: 36466481 PMCID: PMC9716092 DOI: 10.3389/fpubh.2022.992122] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2022] [Accepted: 10/31/2022] [Indexed: 11/19/2022] Open
Abstract
Background Early in the COVID-19 pandemic, it became apparent that members of marginalized populations and immigrants were also at risk of being hospitalized and dying more frequently from COVID-19. To examine how the pandemic affected underserved and marginalized populations, we analyzed data on changes in the number of deaths among people with and without Swiss citizenship during the first and second SARS-CoV-2 waves. Method We analyzed the annual number of deaths from the Swiss Federal Statistical Office from 2015 to 2020, and weekly data from January 2020 to May 2021 on deaths of permanent residents with and without Swiss citizenship, and we differentiated the data through subdivision into age groups. Results People without Swiss citizenship show a higher increase in the number of deaths in 2020 than those who were Swiss citizens. The increase in deaths compared to the previous year was almost twice as high for people without Swiss citizenship (21.8%) as for those with it (11.4%). The breakdown by age group indicates that among people between the ages of 64 and 75, those without Swiss citizenship exhibited an increase in mortality (21.6%) that was four times higher than that for people with Swiss citizenship (4.7%). Conclusion This study confirms that a highly specialized health care system, as is found in Switzerland, does not sufficiently guarantee that all parts of the population will be equally protected in a health crisis such as COVID-19.

Immunohistochemical Changes in the Testicular Excurrent Duct System of Healthy, Male Japanese Quail ( Coturnix coturnix japonica) Observed at 4, 6-7, 12, and 52 Weeks of Age. Int J Mol Sci 2022; 23:ijms232214028. [PMID: 36430504 PMCID: PMC9694578 DOI: 10.3390/ijms232214028] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2022] [Revised: 10/25/2022] [Accepted: 11/09/2022] [Indexed: 11/16/2022] Open
Abstract
The immunolocalization of the cytoskeletal and the extracellular matrix proteins was investigated in the testicular excurrent duct system of healthy Japanese quail at 4, 6−7, 12 and 52 weeks of age. TdT dUTP Nick End Labeling (TUNEL) assay was used to assess apoptotic cell formation. The epithelia of the testicular excurrent duct system in birds of all age groups displayed various immunolabeling intensities and localization of cytokeratin 5 and beta-tubulin, while α-SMA was observed in epithelia only of 4-week-old birds. In all age groups, vimentin immunostaining was observed in the rete testes and efferent ductular epithelia, but not in the epididymal duct unit. The periductal smooth muscle cells of the excurrent duct system displayed variably intense immunopositivity with cytokeratin 5, desmin, fibronectin, α-SMA, and beta-tubulin. Furthermore, beta-tubulin and vimentin immunolabeled endothelial cells and fibroblasts with various intensities, while fibronectin immunostained extracellular matrices surrounding these cells. TUNEL-positive apoptotic cells were observed in the rete testes and efferent ductular epithelia, with increased frequency (p < 0.001) in 52-week-old birds. The study serves as a baseline normal for this region in healthy birds at 4, 6−7, 12, and 52 weeks of age, for comparison in future similar immunohistochemical studies involving environmental toxins affecting this region.

Abstract
Objective The reference ranges of serum thyroid hormone levels are determined by the values of normal subjects aged 15 or 20 to 60 years old in Japan and may differ from the values in elderly patients. In addition, the relationship between the thyroid function and cognitive function remains controversial. We assessed the thyroid function of elderly subjects ≥60 years old and its impact on the cognitive function in Japanese adults. Methods We compared the thyroid function by age group and gender and investigated the effects of cognitive impairment on the thyroid function. This study was a cross-sectional, multi-institutional joint study. Patients The serum concentrations of thyroid hormones in 1,136 patients were measured; however, those taking thyroid hormones, anti-thyroid drugs, and steroid hormones were excluded. Among them, 1,016 cases in which the cognitive function was evaluated were divided into five groups according to their free thyroxine (FT4) levels. Results Excluding overt thyroid dysfunction (5.8%), the average age of the 1,070 remaining patients was 77.5 years old. The rate of cognitive impairment was lowest at FT4 levels of 1.1-1.2 ng/dL and highest at FT4 levels <0.9 ng/dL for both genders. Thyroid-stimulating hormone (TSH) levels in the elderly varied widely by age group and gender. The upper limit of the reference range of TSH for those ≥60 years old may be higher (7.7-9.2 mIU/L for men; 8.2-8.6 mIU/L for women) than the current range for those <60 years old (4.23 mIU/L). Conclusion The thyroid function seemed to be slightly higher (lower TSH and higher FT4) in the population without cognitive impairment than in those with cognitive impairment, except for men in their 90s.

Salam AA. Self-health assessments in Saudi Arabia: Directions for an integrated primary healthcare. J Family Med Prim Care 2022; 11:4919-4931. [PMID: 36505635 PMCID: PMC9731039 DOI: 10.4103/jfmpc.jfmpc_2242_21] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2021] [Revised: 03/01/2022] [Accepted: 04/01/2022] [Indexed: 12/15/2022] Open
Abstract
Background Public health data for dissemination and discussion in Saudi Arabia, for the purposes of primary healthcare, are limited but the new initiatives of General Authority of Statistics creates many national surveys. One of the most recent one, the Family/Household Health Survey - 2017 aims to fill the gaps, at the same time, aids in discussions on primary healthcare. Objectives Analyses done in this research are aimed at appraising the self-assessed health and to examine age-sex and geographic differentials and their probable interconnections with chronic diseases, injuries, and periodic examinations. Data and Methods This survey conducted in October-December, 2017 covered both native and foreigner households from all the 13 administrative areas through a random sample procedure involving primary sampling units and secondary sampling units. A portion of the published data on self-assessment of health, chronic diseases, injuries, and periodic medical examinations were analyzed. Results More than half of the persons in the Kingdom, reportedly, are in good health; more so among females than males: proportions decreased with increasing age up to 40 years, thereafter increased sharply. Moreover, the major regions have lesser proportion of people with good health. Prevalence of chronic diseases increases with age, in both total and native population, but with variations across specific diseases - hypertension, diabetes, cancer, and cardiovascular diseases (CVDs) and with geographic differentials. On the other hand, there are injuries (from traffic accidents and others) occurred at house, work/school, public place, and other places; pertinent with geographic variations. Moreover, age, sex, and regional differences in periodic health examinations have a contributing effect on health assessments. Moreover, the median age shows a pattern resembling adults assessing good health; chronic diseases after 50s; injuries before 40s; periodic medical examinations in 50s; with females at a lower age, in both groups of population. Conclusions The national health system played an important role not only in health status and health assessments but also in building confidence and trust and thereby enhancing optimism, realism, recognition, self-awareness, and acceptance of physical condition. Thus, age, sex, and regional variations in health assessment are born out of chronic diseases, injuries, and periodic medical examinations and also of expectations and experiences. Generation of such information, effective dissemination, and regular discussions at various levels followed by in-depth analyses raise the primary healthcare and thus the population health.

Abstract
Substantial evidence supports that metabolic syndrome (MetS) affects the incidence of several cancers, with different effects according to age group. We hypothesized that MetS has an age-specific effect on the occurrence of prostate cancer. We studied a National Health Insurance Service health checkup cohort. A total of 5,370,614 men in the cohort were categorized into three age groups in 2009 (20-39, 40-64, ≥65). Prostate cancer incidence was estimated on a cumulative basis from 2009 to 2018. We tried to identify the correlation of MetS components and prostate cancer by age group using this large retrospective cohort. MetS components included the body mass index (BMI), waist circumference (WC), hypertension, obesity, hyperlipidemia, cardiovascular disease, smoking, drinking, serum glucose, serum total cholesterol, serum triglyceride, serum high-density lipoprotein (HDL)-cholesterol and serum low-density lipoprotein (LDL)-cholesterol. A multivariate Cox proportional hazard model was used for the incidence of prostate cancer according to the MetS component. In the young age (20-39) group, the MetS component was not related to prostate cancer. In the middle-aged (40-64) group, the presence of MetS, WC, HDL cholesterol, and hypertension was significantly associated with an increased prevalence of prostate cancer. In the old age (≥65) group, the presence of MetS, WC, HDL cholesterol, triglycerides, and hypertension were significant factors for the incidence of prostate cancer. This tendency was marked in BMI>30 in the old age group (odds ratio: 1.32; P<0.0001). MetS components were age-specifically associated with an increased incidence of prostate cancer. Because the MetS components were related to prostate cancer from middle age to old age, preventing MetS for these age groups is crucial.

Abstract
Intimate partner violence (IPV) and its associated factors may vary according to women's age. In this study, we analyze the effect of age on help-seeking behavior and the associated factors among women exposed to IPV in Spain. Using the Spanish Macrosurvey on Gender Violence of 2014, we analyzed the frequency of help-seeking behavior (police report, formal resources, and informal networks of support) in women who were exposed to lifetime physical/sexual or fear-based IPV (n = 1,567 women). We used Poisson regression models to obtain variables associated with support resources. The analysis was carried out in three age groups: young women (16-29 years old), adults (30-49 years old), and older women (50 years and over). Our results show that informal support networks are the most used resource by all women´s age groups. The probability of filing a police complaint increases among women exposured to physical IPV (PRadult : 1.58;
PRelder : 2.17 ). The probability of using formal resources decreased among older women with low family socioeconomic status (PR: 0.80) and in adult women exposed to sexual IPV (PR: 0.78), and increased among young women and adult Spanish women (PRyoung: 1.65; PRadult: 1.34). The use of informal support networks increased among adult women with physical and mental health effects (PR: 1.22). In older women use of informal support networks was associated with the type of IPV (PRphysical: 1.14; PRsexual: 0.88). The presence of minors who witnessed IPV increased help-seeking behavior among adult and older women.In conclusion, the knowledge of the differences in help-seeking strategies by women in different age groups could contribute to designing strategies to promote women's ability to seek formal help when exposed to IPV.

Abstract
South Korea adopted stringent preventive measures against Coronavirus virus disease 2019, resulting in three small and one large outbreaks until January 15, 2022. The fatality rate was 2.5-fold higher during peak transmission periods than in base periods. As new variants of severe acute respiratory syndrome Coronavirus 2 (SARS-CoV-2) are continuously emerging, the need for understanding their epidemic potential remains necessary. In South Korea, the epidemiologic data obtained from mass diagnostic testing enabled investigation of the true number of infected cases, exact incidence, and fatality numbers. Analysis found a similarity between estimated infection rates and confirmed cases. This suggested that the number of confirmed cases had an influence on the fatality rate as a quantitative parameter. The fatality rate decreased even as infection with SARS-CoV-2 variants rose. In comparative analysis, the confirmed cases in young people (ages 20-29) increased prior to every outbreak peak and marked the tipping point in infection spread. These results indicate that a high level of SARS-CoV-2 infection in young population drives peak incidence and mortality across all age groups.

Abstract
INTRODUCTION Exposure to peer aggression (PA) and bullying victimization (BV) are both expressions of peer victimization. OBJECTIVES In four age-sex groups, (1) Can exposure to PA and BV be considered distinct experiences? (2) To what extent do adolescents exposed to PA consider themselves bullying victims? and (3) What is the effect on BV of the number of PA events experienced? METHODS This cross-sectional study evaluated a probabilistic community-based sample of 669 adolescents (11-15 years, 51.7% girls). A three-stage probabilistic sampling plan involved random selection of census units, eligible households, and one target child per household selected. A 15-item scale investigated exposure to PA events (physical aggression, verbal harassment, social manipulation) occurring more than once in the past six months. BV occurring more than once a week or most days in the past six months was investigated after presenting respondents with a BV definition that required them to feel harmed by their victimization experiences. RESULTS Adolescents exposed to PA and/or BV reported PA only (76.2%), BV only (4.7%), and both (19.1%). Rates of BV among those exposed to PA were as follows: 11-to-12-year-old boys (22.7%), 13-to-15-year-old boys (9.7%), 11-to-12-year-old girls (46.5%), and 13-to-15-year-old girls (13.2%). Multiple logistic regression analysis (outcome = BV) found a significant interaction between PA, age, and sex. PA events had a significant effect on BV for all except older girls. CONCLUSION Exposure to PA and BV are different constructs; few older boys exposed to PA consider themselves bullying victims; and older girls are less affected by PA when it comes to BV.

Abstract
Governments have implemented measures to minimize SARS-CoV-2 spread. However, these measures were relaxed, and the appearance of new variants has prompted periods of high contagion known as waves. In Mexico, four waves distributed between July and August 2020, January and February 2021, August and September 2021, and January and February 2022 have appeared. Current health policies discourage mass sampling, preferring to focus on the corrective treatment of severe cases. Outpatients are only advised to undergo brief voluntary confinement and symptomatic treatment, with no follow-up. Therefore, the present study aimed to analyze sex, age, and viral load in outpatients during the four waves in a medium-sized city in Mexico. For each wave, the date of peak contagion was identified, and data were collected within ±15 days. In this regard, data from 916 patients (434 men and 482 women) were analyzed. The age range of positive patients (37-45 years) presented a higher frequency during the first and third waves, while 28-36 years was the most frequent age range during the second and fourth waves, while the viral load values were significantly higher, for both sexes, during the fourth wave. Obtained data of COVID-19 prevalence in population segments can be used for decision-making in the design of effective public health policies.

Abstract
BACKGROUND There are developmental variations in the paranasal sinuses. Our objective is to determine their dimensions and volume stratified by age and sex and define the expected growth pattern. MATERIALS AND METHODS A retrospective, observational study was performed including computed tomography (CT) of patients between 1 and 20 years of age. The volumes of the frontal, sphenoid, and maxillary sinuses were obtained. RESULTS A total of 210 CT were included with a mean age of 10±6.1 years, 106(50.5%) were female. Groups were categorized in ranges of 5 years. Spearman correlation coefficients between the right and left sides were 0.843, 0.711, 0.916 for the frontal, sphenoid and maxillary sinuses. Post-hoc for the categorical age groups demonstrated statistically significant differences with values of p < 0.01, except between age groups 11-15 against ≥ 16 years of age (p = 0.8). Gender-related differences were evident with a higher air volume in girls in the 5-10-year-old group, while boys predominated in the rest of the groups. CONCLUSIONS CT is ideal for pre-surgical sinus assessment. The maximum volume of paranasal sinuses is reached at age 15. There is a clear volumetric difference between age and gender groups. There is a direct relationship between a volume and its contralateral counterpart.

Abstract
BACKGROUND AND OBJECTIVE Sudden cardiac death can be defined as a sudden, unexpected death caused by loss of heart function. Notwithstanding major developments in the diagnosis and treatment of heart disease, it remains the major contributing factor for deaths. This considers the pattern of sudden cardiac deaths.Methodology: This prospective study was conducted on all cases subjected to medico-legal autopsy in the forensic medicine department at a tertiary care hospital for a period of 18 months. All sudden cardiac deaths satisfying the WHO criteria were included. Unknown cases and bodies in advanced stage of decomposition were excluded. RESULTS Sudden cardiac deaths accounted for 55% (82 cases) of 149 cases of sudden natural deaths and 6.5% of total autopsies conducted. The age group most commonly affected by sudden cardiac death ranged from 31 to 50 years. The majority of the cadavers had 90-95% degree of stenosis of left anterior descending artery, 70-80% of right coronary artery and 60-70% left circumflex artery. Coronary insufficiency was the major cause for sudden cardiac deaths with a total of 53 (64.63%) cases. CONCLUSION Sudden cardiac deaths accounted for 6.5% of all the autopsies conducted and males outnumbered females with M:F ratio of 10.7:1, with mean age of 44.5 ± 12.63 years. The largest number - 60.97% - were aged between 31 and 50 years. Coronary insufficiency accounted for 64.63% of sudden cardiac deaths.

Abstract
BACKGROUND Observational data suggest that catheter ablation may be safe and effective to treat younger and older patients with atrial fibrillation. No large, randomized trial has examined this issue. This report describes outcomes according to age at entry in the CABANA trial (Catheter Ablation versus Antiarrhythmic Drug Therapy for Atrial Fibrillation). METHODS Patients with atrial fibrillation ≥65 years of age, or <65 with ≥1 risk factor for stroke, were randomly assigned to catheter ablation versus drug therapy. The primary outcome was a composite of death, disabling stroke, serious bleeding, or cardiac arrest. Secondary outcomes included all-cause mortality, the composite of mortality or cardiovascular hospitalization, and recurrence of atrial fibrillation. Treatment effect estimates were adjusted for baseline covariables using proportional hazards regression models. RESULTS Of 2204 patients randomly assigned in CABANA, 766 (34.8%) were <65 years of age, 1130 (51.3%) were 65 to 74 years of age, and 308 (14.0%) were ≥75 years of age. Catheter ablation was associated with a 43% reduction in the primary outcome for patients <65 years of age (adjusted hazard ratio [aHR], 0.57 [95% CI, 0.30-1.09]), a 21% reduction for 65 to 74 years of age (aHR, 0.79 [95% CI, 0.54-1.16]), and an indeterminate effect for age ≥75 years of age (aHR, 1.39 [95% CI, 0.75-2.58]). Four-year event rates for ablation versus drug therapy across age groups, respectively, were 3.2% versus 7.8%, 7.8% versus 9.6%, and 14.8% versus 9.0%. For every 10-year increase in age, the primary outcome aHR increased (ie, less favorable to ablation) an average of 27% (interaction P value=0.215). A similar pattern was seen with all-cause mortality: for every 10-year increase in age, the aHR increased an average of 46% (interaction P value=0.111). Atrial fibrillation recurrence rates were lower with ablation than with drug therapy across age subgroups (aHR 0.47, 0.58, and 0.49, respectively). Treatment-related complications were infrequent for both arms (<3%) regardless of age. CONCLUSIONS We found age-based variations in clinical outcomes for catheter ablation compared with drug therapy, with the largest relative and absolute benefits of catheter ablation in younger patients. No prognostic benefits for ablation were seen in the oldest patients. No differences were found by age in treatment-related complications or in the relative effectiveness of catheter ablation in preventing recurrent atrial arrhythmias. REGISTRATION URL: https://www.

[PMID: 35329115 PMCID: PMC8953674 DOI: 10.3390/ijerph19063429] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 01/15/2022] [Revised: 02/28/2022] [Accepted: 03/11/2022] [Indexed: 11/25/2022]
Abstract
With the rapidly aging population, taxi drivers are aging at a fast pace, and competition in the taxi industry is intensifying due to the emergence of various transportation platforms. A descriptive secondary data study was conducted (on a total of 936 subjects) to determine the factors affecting the deterioration of taxi drivers’ physical health status (PHS) according to their age group. The increased incidence of chronic diseases and cognitive decline among taxi drivers aged 55−64 years had the greatest influence on the deterioration of their PHS. Driver obesity was more likely to be related to deterioration of the PHS in the drivers aged 55−64 years (OR: 2.459, <0.001) and 35−54 years (OR: 2.133, <0.001). Among the financial factors, a driver’s income and their number of dependent family members were correlated with the deterioration of the PHS for drivers aged 55 years or over. Therefore, chronic diseases, obesity and cognitive decline were related with deterioration of the physical health status. This suggests that attention should be paid to healthcare policies not only for the elderly aged over 65 years but also those aged 50 to 64 years, i.e., middle-aged people at the beginning of the transition to old age.

Abstract
OBJECTIVE This study aimed to assess vitamin D (25OHD) levels in individuals who underwent an examination at a private laboratory (between latitudes 14° and 22° south) over 14 years, stratified by sex, age, and epidemiological profiles, and determine variations in the number of tests performed over the years. METHODS All records of 25OHD tests performed at a private clinical laboratory in Brazil were analyzed. This retrospective cross-sectional study included patients stratified by sex (female or male), age range (0-17, 18-40, 41-59, and ≥ 60 years), and year of testing. The final sample size was 193,725 patients. Categorical variables are presented as absolute and relative frequencies and numerical variables as means ± standard deviation. Comparisons between groups were performed using the equality of proportions test. RESULTS The number of tests performed steeply increased since 2010. More tests were performed in female individuals (73.3%) and individuals aged 41-59 years (32.2%). Most samples (68.0%) demonstrated sufficient vitamin D status. Women had a higher incidence of vitamin D deficiency than men (33.1% and 26.6%, respectively; p < 0.001). Individuals aged ≥ 60 years had the highest incidence of vitamin D deficiency (68.4%), while individuals aged 0-17 years had the lowest (32.2%) (p < 0.001). CONCLUSION Despite increased testing and attention given to vitamin D in recent years, our study demonstrates high levels of deficiency in a country with geographical conditions favorable to its production.

Abstract
The study found that the 2013-2019 period saw a decrease in the incidence of primary disability caused by hip joint injuries among the adult population of Moscow. The level of primary disability averaged 0.09 ± 0.03 per 10,000 adult population. In the structure of disability caused by injuries of the lower limbs, hip joint injuries accounted for 10.5% over the studied period. The age structure was dominated by disabled people above the working age with a tendency to decrease their share. In the nosological structure, people disabled as a result of femoral neck fractures (46.2%) and femur fractures (29.3%) prevailed. In the structure of people who were first recognized as disabled, disabled people of groups II and III prevailed (with a large proportion of disabled people of group III and a lower share of disabled people of group II). The proportion of people with disabilities in group I is the smallest, and it tends to decrease over the studied period. Among people above the working age, the disabled people of groups I and II prevailed while among people of the working age, the disabled people of groups II and III prevailed.The incidence of repeated disability of this contingent was also characterized by a downward trend. The level of repeated disability averaged 0.11 per 10,000 population. The share of people repeatedly recognized as disabled due to injuries of the lower limbs was 8.5%. The structure was dominated by people with disabilities caused by femoral neck and femur fractures. The period saw an increase in the proportion of disabled people of the working age. The disabled people of group III with a tendency to increase their share and the disabled people of group II with a tendency to decrease their share prevailed, and the number of disabled people of group I decreased.

Abstract
BACKGROUND Reverse transcription-polymerase chain reaction (RT-PCR) is a standard technique for diagnosing coronavirus disease 2019 (COVID-19). The parameters for the diagnosis of COVID-19 included the history of exposure to positive COVID-19 patients, clinical signs and symptoms related to the disease, inflammation factors in the blood test or positive antigen-antibody test, and chest computed tomography (CT) findings. The current study evaluated the chest CT scan findings in patients with respiratory problems following positive RT-PCR of COVID 19. MATERIALS AND METHODS This cross-sectional study was performed on 120 patients referred to Ali Ibn-Abi Talib Hospital in Rafsanjan, Kerman Province, Iran, with respiratory symptoms between Dec-2019 to Dec-2020. Two radiologists reviewed the chest CT scans of these patients using the checklist that included parameters such as the types of involvement (consolidation/grand-glass/crazy paving, etc.) and the patterns of involvement (central/peripheral), and the pleural findings. RESULTS The CT scan was conducted in 107 patients with a typical condition and 11 patients with an atypical form of the disease. The frequency of the typical CT image of COVID-19 in the male group was significantly higher than that in the female group (P=0.004). The frequency of reverse halo sign, septal thickening, cardiomegaly, and crazy paving was significantly higher in males than in females (P≤0.05). Also, there was a significant difference between age groups based on the number of involved lobes (P=0.04). CONCLUSION Chest CT scan is an important diagnostic method for COVID 19 with high sensitivity. The parameters in the CT scan are beneficial for the diagnosis of COVID 19. In addition, some characters in CT scans in the male gender are more specific.

Age-specific effectiveness of primary human papillomavirus screening versus cytology in a cervical cancer screening program: a nationwide cross-sectional study. Cancer Commun (Lond) 2022; 42:191-204. [PMID: 35142100 PMCID: PMC8923126 DOI: 10.1002/cac2.12256] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2021] [Revised: 10/22/2021] [Accepted: 12/30/2021] [Indexed: 12/30/2022] Open
Abstract
BACKGROUND Primary human papillomavirus (HPV) screening is recommended for the detection of cervical intraepithelial neoplasia (CIN) in the general population; however, the triage for HPV-positive women remains a challenge. This study aimed to evaluate the age-specific effectiveness of primary HPV screening versus primary cytology screening for identifying optimal strategies for women of different ages. METHODS The dataset of the prevalence round screening was derived from the National Cervical Cancer Screening Program in China. Primary cervical screening protocols included cytology only, HPV testing with cytology triage, and HPV testing with HPV-16/18 genotyping plus cytology triage. The primary outcomes were age-specific detection rate, colposcopy referral rate and positive predictive value (PPV) for CIN2+. Multivariate Poisson regression was used to evaluate the relative effectiveness of HPV testing and cytology according to age groups. The I2 statistic with a random-effect model was used to test the heterogeneity in relative effectiveness of HPV testing versus cytology between age groups. RESULTS This study included 1,160,981 women. HPV testing with HPV-16/18 genotyping plus cytology triage significantly increased the CIN2+ detection by 36% (rate ratio [RR]: 1.36, 95% confidential interval [CI] 1.21-1.54) for women aged 35-44 years and by 34% (RR: 1.34, 95% CI 1.20-1.51) for women aged 45-54 years compared with cytology only. HPV testing with cytology triage had similar CIN2+ detection rate compared with cytology only. The PPVs were substantially increased for both HPV testing groups. Among women aged 55-64 years old, HPV testing with HPV-16/18 genotyping plus cytology triage increased the colposcopy referral rate by 19% (RR 1.19, 95% CI 1.10-1.29) compared with cytology only, but did not increase the CIN2+ detection (1.09, 0.91-1.30). The effectiveness of HPV testing with cytology triage did not change in older women. The between-age-group heterogeneity in the effectiveness was statistically significant for HPV testing with HPV-16/18 genotyping plus cytology triage versus cytology only. CONCLUSIONS Our results suggested that the effectiveness of primary HPV screening with different triage strategies differed among age groups. HPV testing with HPV-16/18 genotyping plus cytology triage could be used for women aged 35-54 years to detect more lesions, and HPV testing with cytology triage could balance the CIN2+ detection and the number of colposcopies for women aged 55-64 years. Longitudinal data including both prevalence and incidence screening rounds are warranted to assess age-specific triage strategies.

Age and sex differences in factors associated with hypertension among an urban poor population in Bangladesh. NAGOYA JOURNAL OF MEDICAL SCIENCE 2022; 84:69-79.

Abstract
This study explores the differences in factors associated with hypertension between younger and older subjects in an urban slum community in Bangladesh. We analyzed the data of 1,008 men and 1,001 women obtained from a cross-sectional survey conducted between October 2015 and April 2016. Multivariable logistic regression models were stratified by age (18 to 44 and 45 to 64 years) in men and women separately. The multivariable model included age (continuous) and the following categorical variables simultaneously: education duration, marital status, tobacco smoking, smokeless tobacco use, total physical activity, body mass index (BMI), waist circumference, and the blood levels of glycated hemoglobin (HbA1c), triglycerides, high- and low-density lipoprotein (HDL and LDL) cholesterol. Hypertension was defined as the presence of either blood pressure ≥140/90 mmHg or the use of antihypertensive medication. The prevalence of hypertension was 13.0% (younger men), 14.6% (younger women), 35.6% (older men), and 38.7% (older women). In younger men, higher waist circumference and increased LDL cholesterol levels were significantly associated with hypertension. In older men, physical activity was the only significant factor that was inversely associated with hypertension. In younger women, higher BMI, increased HbA1c, triglycerides, and LDL cholesterol levels were associated with hypertension. In older women, a higher HbA1c was the only factor significantly associated with hypertension. These findings suggest that public health interventions to prevent hypertension may require different approaches according to sex and age groups within the poor urban population in Bangladesh.

Abstract
Marital status mediates an association between physical activity (PA) and TV time with health outcomes. However, population-based studies have revealed that the health effect of marriage or divorce is age-dependent and differs between women and men. The study aimed to identify the age and sex-related associations between marital status with PA and TV time. We used data from Vigitel, an annual telephone survey started in 2006 in Brazil. We applied a complex sample logistic regression model to estimate the odds for PA and TV time comparing marital statuses according to age and sex subgroups, independent of obesity, hypertension, diabetes, self-assessed poor health, and smoking. Our sample included 561,837 individuals from 18 to 99 years, with a TV time > 3 h/day (prevalence = 25.2%) and PA > 150 min/week (prevalence = 35%). Later, we divided our sample in seven age groups by marital status and sex. Compared to single individuals, married men and women were less likely to watch TV more than 3 h/day in participants >30 years old. When compared to single, married participants were less likely to do more than 150 min of PA/week at younger age groups. Married women older than 40 years were more likely to do more than 150 min of PA/week than the single ones, while there were no differences among married men by age group. In conclusion, our study suggests that the investments in public policies to encourage the practice of PA and reduction of TV time could be based on the marital status, sex, and age, prioritizing less active groups.

Abstract
Infectious disease transmission models often stratify populations by age and geographic patches. Contact patterns between age groups and patches are key parameters in such models. Arenas et al. (2020) develop an approach to simulate contact patterns associated with recurrent mobility between patches, such as due to work, school, and other regular travel. Using their approach, mixing between patches is greater than mobility data alone would suggest, because individuals from patches A and B can form contacts if they meet in patch C. We build upon their approach to address three potential gaps that remain, outlined in the bullets below. We describe the steps required to implement our approach in detail, and present step-wise results of an example application to generate contact matrices for SARS-CoV-2 transmission modelling in Ontario, Canada. We also provide methods for deriving the mobility matrix based on GPS mobility data (appendix). • Our approach includes a distribution of contacts by age that is responsive to the underlying age distributions of the mixing populations. • Our approach maintains different age mixing patterns by contact type, such that changes to the numbers of different types of contacts are appropriately reflected in changes to overall age mixing patterns. • Our approach distinguishes between two mixing pools associated with each patch, with possible implications for the overall connectivity of the population: the home pool, in which contacts can only be formed with other individuals residing in the same patch, and the travel pool, in which contacts can be formed with some residents of, and any other visitors to the patch.

Abstract
Introduction Although boys tend to be more affected by linear growth faltering than girls, little is known about sex differences across distinct age groups. We aimed to compare sex differences in linear growth throughout the first 5 years of life among children from low-income and middle-income countries. Methods We analysed 87 cross-sectional Demographic and Health Surveys and Multiple Cluster Indicator Surveys (2010–2019). Growth was expressed as height-for-age z-scores (HAZ) based on the 2006 WHO Growth Standards. Sex-specific means were estimated for each country and results were pooled through random-effects meta-analysis for all children and by 12-month age groups. Using linear regression, we assessed the association between sex differences in HAZ and gross domestic product as a proxy for national economic development. Results Boys presented lower mean HAZ than girls in the first 30 months. Sex differences were mostly absent between 30 and 45 months, and in several countries, girls had lower HAZ at ages over 45 months. The pooled sex difference (boys minus girls) for the whole sample was −0.10 (95% CI −0.12 to −0.08). The difference was −0.17 (95% CI −0.20 to −0.14) at 0–11 months and −0.22 (95% CI −0.25 to −0.19) at 12–23 months. This was followed by a narrowing of the sex gap to −0.10 (95% CI −0.13 to −0.07) and −0.04 (95% CI −0.07 to −0.01) among children aged 24–35 and 36–47 months, respectively. At 48–59 months, there was evidence of female disadvantage; the mean height-for-age of boys was 0.02 (95% CI 0.00 to 0.05) SDs higher than for girls. Ecological analyses showed that in all age groups, male disadvantage decreased with increasing national income, and this was no longer present for the 4-year-old children, particularly in wealthier countries. Conclusion Male disadvantage in linear growth is most evident in the first years, but by the age of 4 years, the sex gap has mostly disappeared, and in some countries, the gap has been reversed.

Abstract
Objectives People with ileus is one of the patient groups with the highest admission rates to the emergency departments. In this study, it was aimed to determine the effects of age groups and etiological factors on mortality when evaluated together with gender. Material and Methods In our study, patients who were consulted from the Emergency Service to the General Surgery department with a pre-diagno- sis of abdominal pain between 2009 and 2020 were retrospectively screened. Patients hospitalized for ileus were analyzed in terms of age (18-65 years and over 65 years), gender, operation, etiology, incidence, and mortality. Results Between 2009 and 2020, 534 (3.03%) of 17.601 patients who received emergency consultation from the general surgery clinic were diagnosed with ileus. While 253 (47.4%) of the patients were operated, 317 (59.4%) patients and 101 (18.9%) patients were diagnosed with brid and malignancy, respectively; and 21 (3.9%) patients died in the complete patient group (Table 1). While the incidence of brid was high in non-operated patients, in operated patients, malignancy and other pathologies was found to be higher (p <0.001) (Table 2). While, in patients 65 years and older, mortality was observed in 10.6% of women and 2.6% of men, it was determined that the mortality rate was higher in women (p= 0.008) (Figure 4). Conclusion The mortality rate in patients hospitalized with the diagnosis of mechanical bowel obstruction was found to be statistically significantly higher in female patients aged 65 and over.

Abstract
Although there is no age criterion for rivaroxaban dose reduction, elderly patients with atrial fibrillation (AF) are often prescribed an off-label reduced dose. We aimed to evaluate whether age is a necessary criterion for rivaroxaban dose reduction in Korean patients with AF. Among 2208 patients who prescribed warfarin or rivaroxaban, 552 patients over 75 years without renal dysfunction (creatinine clearance >50 mL/min) were compared based on propensity score matching. The rivaroxaban group was further divided into a 20 mg (R20; on-label) and a 15 mg (R15; off-label). Primary net clinical benefit (NCB) was defined as the composite of stroke, systemic embolism, major bleeding, and all-cause mortality. Secondary NCB was defined as the composite of stroke, systemic embolism, and major bleeding. Patients were followed for 1 year, or until the first outcome occurrence. Both rivaroxaban groups had comparable efficacy compared with warfarin. However, both R20 (0.9% vs 7.4%, p = .014) and R15 (2.3% vs 7.4%, p = .018) had a significant reduction in major bleeding. There were no differences in efficacy or safety outcomes between R20 and R15. R20 had significantly reduced primary (hazard ratio [HR] 0.33, 95% confidence interval [CI]: 0.12–0.93) and secondary (HR 0.31, 95% CI: 0.10–0.93) NCBs compared with warfarin. However, primary and secondary NCBs were not reduced in R15. In real-world practice with elderly patients with AF, off-label rivaroxaban dose reduction to 15 mg conferred no benefits. Therefore, guideline-adherent rivaroxaban 20 mg is favorable in elderly Korean patients with AF.

Abstract
In recent years, whole-body vibration (WBV) training has been used as a training method in health promotion. This study attempted to use WBV at three different frequencies (20, 30, and 40 Hz) with subjects from different age groups to analyze the activation of the rectus femoris muscle. The subjects included 47 females and 51 males with an average age of 45.1 ± 15.2 years. Results indicated significant differences in subjects from different age groups at 20 Hz WBV. Muscle contraction was greater in the subjects who were older (F(4,93) = 82.448, p < 0.001). However, at 30 Hz WBV, the difference was not significant (F(4,93) = 2.373, p = 0.058). At 40 Hz WBV, muscle contraction was less in the older subjects than in the younger subjects (F(4,93) = 18.025, p < 0.001). The spectrum analysis also indicated that at 40 Hz there was less muscle activity during WBV in the older subjects than in the younger ones. Therefore, age was found to have a significant effect on muscle activation during WBV at different frequencies. If the training is offered to elderly subjects, their neuromuscular responses to 20 Hz WBV will be more suitable than to 40 Hz WBV.
