BACKGROUND: Baseline data are needed to provide a foundation for future studies investigating the effects of various nursing interventions on the oxygen requirements of critically ill patients. OBJECTIVES: To establish reference values for the oxygen requirements of adults in response to three common patient events: a nurse-administered bed bath, passive range-of-motion exercises, and turning from side to side; and to determine whether the order in which the interventions were administered had an effect on oxygen consumption. METHODS: A convenience sample of 30 healthy men and women were randomly assigned to one of three treatment groups, for which the order in which interventions were to be administered had previously been designated. Data were analyzed using analysis of variance with repeated measures. RESULTS: There was a significant difference in the mean oxygen consumption among activities, as well as between men and women, with men having a significantly higher mean oxygen consumption than that of the women. For both men and women, the mean oxygen consumption during unassisted turning and back care was significantly higher than at baseline. The oxygen consumption for men averaged 4.25 mL/kg per minute, SD = .71 at baseline, 5.08 mL/kg per minute, SD = .98 for turning, and 4.72 mL/kg per minute, SD = .90 during back care. Women averaged 3.74 mL/kg per minute, SD = .49 at baseline, 4.48 mL/kg per minute, SD = .85 for turning, and 3.89 mL/kg per minute, SD = 1.15 during back care. Changes in oxygen consumption for other interventions were nonsignificant and negligible. Oxygen consumption returned to near baseline within 15 minutes of cessation of activity. The order in which interventions were administered did not have a significant effect on oxygen consumption. CONCLUSIONS: The anterior bath and passive range of motion exercises have minimal effect on oxygen consumption. Turning and back care significantly increase oxygen consumption from the baseline value. The order in which interventions are administered does not have any appreciable effect on oxygen consumption.

Commit Suicide

The abuse of some pesticides especially to suicide is one of the current problems of pesticides. Aluminum phosphide induced poisoning usually happens to suicide and sometimes it is due to accidental occupational exposure and in a few cases it has some criminal intensions. This study is conducted to evaluate patients poisoned with aluminum phosphide. In the present study the medical records of cases of poisoning with rice tablets (aluminum phosphide) hospitalized in Ahvaz Razi hospital is studied. Accordingly, a checklist is prepared that included demographic information of patients (age, gender) and information on patient records (information on poisoning) are completed using the patients’ medical records. The analysis of data is done by SPSS V22. 18 patients poisoned with rice tablet (aluminum phosphide) are studied. Results of the study show that 11 patients are male and seven are female. The mean patient age is 27.06 ±8.04 years that is 28 ±9 and 25 ±6.02 in men and women respectively. Statistical tests show no statistically significant difference in mean age in both genders (P> 0.05). Among patients, 11 subjects took aluminum phosphide to attempt suicide and 3 cases took it unintentionally and of course the reason is not mentioned in four cases. Among the patients who tried to commit suicide by taking aluminum phosphide, 6 cases are male and 5 cases are female that no statistically significant difference is observed between the genders in this respect (P> 0.05). In addition to the study of the complications caused by this poisoning and its mortality, it is recommended to responsible authorities to provide the necessary educations and treatments to prevent this type of poisoning.

Heat-acclimated, lightly clothed men and women (four of each) walked on a treadmill at 25% and 43% VO2 max, respectively, (M =194 W.m-2), under seven air temperatures (Ta) ranging from 36 to 52 degrees C. Each experiment involved 1 h of fixed and a 2nd h of progressively increasing ambient vapor pressure (Pa). The relative steady state of rectal temperature (Tre), mean skin temperature (Tsk), and heart rate (HR) reached in the 1st h were forced upward during the 2nd h by the rising Pa. The critical air vapor pressure (Pcrit) was identified by the Tre point of inflection for each Ta. One man did not fully reach steady state, but inflection could be determined for his physiological responses. The mean values of all points of inflection were calculated for Tre, Tsk, and HR. Significant sex difference in HR was found only by excluding the results of the one man. Tre and Tsk showed no significant difference between men and women. The coefficient for evaporative heat transfer (he), which could be derived using the Pcrit for the low Ta range, was 14.5 +/- 2.2 W.m-1 Torr-1.

Volumetric Measurements

The objective of this study is to investigate the dimensional and volumetric measurements in the thyroarytenoid (TA) muscle in men and women using magnetic resonance imaging (MRI). The hypothesis is that there is a gender-related difference in these measurements. A retrospective chart review of 76 patients who underwent MRI of the neck at the American University of Beirut Medical Center was conducted. The dimension and volume of the right and left TA muscle were measured on axial and coronal planes short tau inversion recovery images. Male and female groups were compared with respect to demographic data and MRI findings using parametric and nonparametric tests. The mean length of the thyro-arytenoid muscle in males was larger than that in females on the right (males 2.44 [0.29] cm vs females 1.70 [0.22] cm) and on the left (males 2.50 [0.28] cm vs females 1.72 [0.24] cm) reaching statistical significance ( P < .001). The mean width of the thyro-arytenoid muscle in males was larger than that in females on the right (males 0.68 [0.13] cm vs females 0.59 [0.11] cm) and on the left (males 0.68 [0.12] cm vs females 0.57 [0.12] cm) reaching statistical significance ( P < .001). The mean height of the thyro-arytenoid muscle in males was larger than that in females on the right (males 1.05 [0.21] cm vs females 0.95 [0.12] cm) and on the left (males 1.05 [0.21] cm vs females 0.95 [0.12] cm) reaching statistical significance ( P < .01 on the right and P < .05 on the left). The volume of the thyroarytenoid muscle in males was larger than that in females on the right (males 0.86 [0.25] mL vs females 0.48 [0.15] mL) and on the left (males 0.89 [0.27] mL vs females 0.48 [0.17] mL) reaching statistical significance ( P < .001). The results of this investigation clearly indicate a significant difference in these measurements between men and women.

On the first and last days of the semester, 28 literature students (8 men, 20 women) rated themselves according to Spence and Helmreich's 1978 Personality Attributes Questionnaire. As expected, no significant differences between men and women appeared in comparisons of the scores of the dualistic Instrumental (Masculine or M) and Expressive (Feminine or F) traits from the first and second administrations. However, the combined scores of men and women for the bipolar M-F traits showed a significant difference between their initial responses and their second responses to the M-F traits. Further, men had significantly higher mean scores than did women for the first and second administrations. The mean scores on the second administration suggest that men had reinforced their initial stereotypical self-image of themselves, while women had appropriated manifestations of dominance in their self-ideal.

AbstractBackground: Type 2 myocardial infarction (MI) is defined as MI secondary to ischemia due to either increased oxygen demand or decreased supply. It is seen in conditions other than coronary artery disease (CAD) contributes to an imbalance between myocardial oxygen supply and/or demand. Little is known about patient characteristics and clinical outcomes.Methods: A retrospective analysis was performed in patients who were admitted in acute medical care with symptoms suggestive of myocardial ischemia and enzymatic elevation from January 2015 to December 2015. Patients with slight elevation (above the upper limit of normal) of CK-MB were included in the study and compared the clinical and laboratory profile between men and women.Results: This survey includes a total of 54 patients, Out of which complete details were available in 41 patients (M:23; F:18). The mean age was 42.61. The common causes of type-II MI were Infectious (M:9 (39.1%), F:10 (55.6%) followed by haematological disorders (M:3 (13%), F:5 (27.7%). The mean CK-MB was 28.00. The mean CPK was 122.5. There was no hypotension, renal failure at the time of admission. One patient had in-hospital mortality out of all patients, whose primary diagnosis was septicaemia with shock who had normal CPK, elevated CK-MB and elevated NT pro BNP levels. Patients with type-II MI were not referred for coronary interventions and managed conservatively.Conclusions: There is no significant difference in the risk for type 2 MI between men and women. Clinical suspicion and diagnosis of type 2 MI is crucial in acute medical care setting, as the mortality can be reduced with adequate management of underlying condition. The threshold of biomarker levels should be low (above the upper limit of normal in symptomatic ischemia) to label type 2 MI contrary to the third universal definition of MI.

Abstract The purpose of this study was to compare attitudes about aging between groups of raters categorized by gender, using the Aging Semantic Differential (ASD; Rosencrantz & McNevin, 1969) and the Fraboni Scale of Ageism (FSA, Fraboni, Saltstone, & Hughes, 1990). The current study assesses the relationships between the four factors of Aging Semantic Differential (ASD; Instrumentality, Autonomy, Acceptability, and Integrity) as well as the three factors of the Fraboni Scale of Ageism (FSA; Antilocution, Discrimination, and Avoidance) across gender groups. The convenience sample consisted of 471 undergraduate students, with a mean age of 19.68 (SD = 2.28). The mean age for men was 19.88 (SD = 3.31) and for women was 19.56 (SD = 1.37). A series of four ANOVAs were conducted using the ASD factors. Results showed significance for the ASD-Instrumental (F(1, 470) = 4.922, p = .027); ASD-Acceptability F(1, 470) = 8.616, p = .003), and the ASD-Integrity factors F(1, 470) = 4.475, p = .035). Men endorsed more positive attitudes than women on both the Acceptability and Integrity factors. Women endorsed more positive attitudes on the Instrumental factor. Similar ANOVAs were conducted across the three Fraboni Scale of Ageism factors. Significant differences between men and women were only obtained across the Avoidance factor (F(1, 470) = 12.187, p = .001) with endorsing higher avoidance scores than women. Taken together these results show differential effects across three ASD factors between men and women while men demonstrated higher scores on the FSA Avoidance scale.

Cellular Entry

Angiotensin-converting enzyme 2 (ACE2) facilitates the cellular entry of the severe acute respiratory syndrome-associated coronavirus 2 (SARS-CoV-2), which causes the coronavirus-2019 (COVID-19) disease. Recent reports have shown worse outcomes in men with COVID-19 infection compared to women. We review the hypothesis that sex-related differences in outcomes in COVID-19 are due to different activity of ACE2 between men and women. We also show that studies in humans have demonstrated no significant difference in serum ACE2 levels between healthy men and women. However, men with hypertension and heart failure typically have higher level of serum ACE2 activity compared to women. We hypothesize that the worse outcomes in men with COVID-19 compared to women is likely due to higher prevalence of hypertension and heart failure among men compared to women. To test this hypothesis, studies to compare the outcomes of COVID-19 infection between men and women with no preexisting heart diseases are needed.

BackgroundStable access is essential for successful intracranial interventions. Quantifying variations in extracranial carotid arteries may help in the selection and development of access catheters. This study describes the vascular dimensions from the aortic arch to the skull base.MethodsCT angiography analysis was performed on 100 patients. The lengths, diameters, and tortuosity of the common carotid artery (CCA) and internal carotid artery (ICA) were measured from the aortic arch to the skull base.ResultsThe mean±SD length of the carotid artery from the aortic arch to the skull base was 22.2±2.2 cm for the right side and 20.8±1.9 cm for the left side (p<0.0001). The length of the right CCA was 13.6±1.2 cm and the length of the left CCA was 12.4±1.4 cm (p<0.0001). The length of the right ICA was 8.6±1.4 cm compared with 8.4±1.4 cm for the left ICA (p=0.3). The ICA length in men and women was 8.9±1.3 cm and 8.2±1.3 cm, respectively (p=0.0001), and the CCA length in men and women was 13.6±1.5 cm and 12.3±1.6 cm, respectively (p<0.0001). The lengths of the CCA and ICA in patients aged ≥60 years were 13.3±1.7 cm and 8.9±1.5 cm, respectively compared with 12.8±1.7 cm and 8.2±1.1 cm, respectively, for patients aged <60 years (p=0.04 for CCA, p=0.0002 for ICA). Tortuosity of the CCA and ICA was 1.2±0.2 and 1.3±0.1, respectively, in patients aged ≥60 years compared with 1.1±0.1 for both the ICA and CCA in patients aged <60 years (p<0.0001 for both). There was a consistent ratio of CCA/ICA length of 1.6±0.3 on the right and 1.5±0.3 on the left (p<0.0001). The arterial diameters did not show any significant difference.ConclusionsThe distance from the aortic arch to the skull base is longer on the right than on the left side. Both the CCA and ICA are longer in men and in patients aged ≥60 years. The tortuosity of both segments significantly increases with age.

ObjectivesIn recent years, studies have demonstrated frequent rectal Chlamydia trachomatis (CT) detection in women, irrespective of reported anal sex or rectal symptoms. However, the clinical relevance and public health implication of rectal CT detection in women remain under debate. Therefore, evaluating CT viability may provide more insight into the relevance of standard routine nucleic acid amplification test (NAAT)–positive results.MethodsIn this cross-sectional explorative study, a convenience sample of female patients at our STI clinic aged 18 years or older, diagnosed with vaginal and/or rectal CT, were invited to participate. On return for treatment, rectal CT-diagnosed women were instructed to self-collect rectal swab samples before being treated. Standard COBAS 4800 CT/NG routine NAAT testing was applied for CT diagnosis. Rectal viable CT load was evaluated by using viability-PCR (V-PCR).Results53 women with rectal CT were included in this study; 86.8% (46/53) had a quantifiable rectal total CT load. Of women with quantifiable samples, 52.2% (24/46) had viable CT detected from rectal swabs by V-PCR, with a mean rectal viable CT load of 3.31 log10 CT/mL (range 1.16–6.22). No statistically significant difference (p=0.73) was observed in the mean rectal viable CT load of women with an indication for rectal testing (n=9) and without (n=15), 3.20 log10 CT/mL (range 2.06–4.36) and 3.38 log10 CT/mL (range 1.16–6.22), respectively. CT culture yielded positive test results from rectal swabs in 22.6% (12/53) of rectal CT NAAT-diagnosed women. Of women with viable rectal CT by V-PCR (n=24), 50% (12/24) were positive by CT culture.ConclusionsOverall, the detection of high rectal viable CT loads in this study indicates that rectal CT in some women might represent a currently ongoing infection rather than just the presence of remnant DNA from dead bacteria or only contamination from an active vaginal CT infection.

Abstract Background. To the best of our knowledge, no published English literatures has provided detailed parameters about the normal epidural fat and other contents in lumbar spinal canal. Our objective was to quantify reference data of epidural fat and the contents of lumbar spinal canal to guide the diagnosis of lumbar epidural lipomatosis.Methods. 178 content lumbar MRI cases were analysis on Picture Archiving and Communication Systems (PACS).Results. the mean anteroposterior ( AP ) diameters ± standard deviation(SD) of lumbar vertebral body ( V )、dural sac ( DS )、epidural fat ( EF ) each measured lever on the mid-sagittal MRI and the mean cross-sectional area ± SD of lumbar spinal canal ( SC )、DS of each measured lever on the axial MRI were showed. The mean AP diameters of V and DS are showed obvious significant difference between men and women ( P ＜0.05). The mean AP diameters of EF is showed no significant difference between men and women (P ＞0.05). Also The mean area of lumbar SC (male 316.7 mm2, female 306.4 mm2 ) and DS (male 198.6 mm2, female 189.2 mm2) are showed obvious significant difference between men and women ( P ＜0.05). The growth trend of the thickness of epidural fat in lumbar spinal canal is showed.Conclusion. Our investigation provides insight into the anatomy of epidural fat and gives the relevant parameters of lumbar spinal canal and its contents on MRI. MRI is the most sensitive imaging test to diagnose lumbar epidural lipomatosis
