Cardiovascular Risk: Gender Differences in Lifestyle Behaviors and Coping Strategies

Background

Although cardiovascular disease (CVD) does not occur until mid to late life for most adults, the presence of risk factors, such as high blood pressure (BP) and cholesterol, has increased dramatically in young adults.

Purpose

The present study examined the relationships between gender and coping strategies, lifestyle behaviors, and cardiovascular risks.

Method

The sample consisted of 297 (71% female) university students. Participants completed a survey to assess demographics, lifestyle behaviors, and coping strategies, and a physiological assessment including lipid and blood pressure (BP) measurements. Data collection occurred from January 2007 to May 2008.

Results

Analyses revealed that age, ethnicity, greater body mass index (BMI), greater use of social support, and less frequent exercise were associated with higher cholesterol, while gender, age, greater BMI, and less frequent exercise were associated with higher systolic BP. There were two significant interactions: one between gender and avoidant coping and the other between gender and exercise on systolic BP, such that for men greater use of avoidant coping or exercise was associated with lower systolic BP.

Conclusion

Understanding how young adults manage their demands and cope with stress sets the stage for understanding the developmental process of CVD. Both coping strategies and lifestyle behaviors must be considered in appraising gender-related cardiovascular risk at an early age before the disease process has begun.     

Relationship between testosterone deficiency and cardiovascular risk and mortality in adult men

Classic male hypogonadism is associated with known adverse effects including decreased libido, erectile dysfunction, osteoporosis, and changes in body composition. Recently, we have come to appreciate that reduction in serum testosterone (T) levels resulting from aging or chronic disease or androgen deprivation therapy (ADT) have consequences similar to those seen in classic male hypogonadism which include increased fat mass, decreased lean body mass, decreased muscle strength, and sexual dysfunction. These data suggest that low T levels may represent a newly recognized cardiometabolic risk factor. Therefore, we carried out a careful review of the literature, focusing on major turning points of research and studies which gave more important and controversial contribution to the cardiovascular role of T. Observational studies and clinical trials investigating the relationship between T levels and cardiovascular disease and mortality were identified byMedline search. The results were synthesized, tabulated, and interpreted. The aim of this review is to discuss the association between low T levels and adverse metabolic profile such as insulin resistance, metabolic syndrome, and diabetes. We will also investigate the potential mechanisms by which male hypogonadism, especially age related or induced by ADT, may increase cardio-metabolic risk. Finally we will detail the emerging relationship between low T and mortality in men addressing also the reverse hypothesis that low T has a protective role by turning off T-dependent functions.     

Behavioral parent training to address sleep disturbances in young children with autism spectrum disorder: a pilot trial

Objectives

A large percentage of children with autism spectrum disorders (ASD) have bedtime and sleep disturbances. However, the treatment of these disturbances has been understudied. The purpose of our study was to develop a manualized behavioral parent training (BPT) program for parents of young children with ASD and sleep disturbances and to test the feasibility, fidelity, and initial efficacy of the treatment in a small randomized controlled trial (RCT).

Participants and methods

Parents of a sample of 40 young children diagnosed with ASD with an average age of 3.5 years were enrolled in our study. Participants were randomized to either the BPT program group or a comparison group who were given nonsleep-related parent education. Each participant was individually administered a 5-session program delivered over the 8-week study. Outcome measures of feasibility, fidelity, and efficacy were collected at weeks 4 and 8 after the baseline time point. Children’s sleep was assessed by parent report and objectively by actigraphy.

Results

Of the 20 participants in each group, data were available for 15 participants randomized to BPT and 18 participants randomized to the comparison condition. Results supported the feasibility of the manualized parent training program and the comparison program. Treatment fidelity was high for both groups. The BPT program group significantly improved more than the comparison group based on the primary sleep outcome of parent report. There were no objective changes in sleep detected by actigraphy.

Conclusions

Our study is one of few RCTs of a BPT program to specifically target sleep disturbances in a well-characterized sample of young children with ASD and to demonstrate the feasibility of the approach. Initial efficacy favored the BPT program over the comparison group and suggested that this manualized parent training approach is worthy of further examination of the efficacy within a larger RCT.     

Validation of the human activity profile in stroke: a comparison of observed, proxy and self-reported scores

PURPOSE: To assess the concurrent validity of the Human Activity Profile (HAP) with stroke and healthy control individuals, when reported by the subject or a proxy and compared to observed performance, used as gold standard; factors related to discrepancies; as well as to determine variables that could best predict physical activity levels. METHODS: A total of 24 stroke and 23 healthy control subjects took part in the study. Functional outcome measures included personal/demographic factors, HAP, the 10-meter walk, and cognition. RESULTS: Strong relationships were found between self-reported and observed scores for both groups (r=0.89-0.99). The relationships between proxy and observed scores were acceptable for stroke (r=0.80-0.87) but lower for control subjects (r=0.65-0.75), with intraclass correlation coefficients (ICCs) ranging from 0.69-0.89. Significant differences were found between proxy and observed scores for stroke, but not for control subjects. Discrepancies between scores showed little predictability from selected variables. For stroke subjects, the strongest variable explaining physical activity levels was walking speed (r2=43%) and the best combination of variables was walking speed plus cognition (r2=55%). CONCLUSIONS: Self-reported HAP was an excellent measure both for stroke and control subjects and related well to observed performance. Proxy reports appear to be valid for stroke subjects. HAP was significantly related to measures of walking speed.     

Adaptability on Shifting Ground: a Rapid Qualitative Assessment of Multi-institutional Inpatient Surge Planning and Workforce Deployment During the COVID-19 Pandemic

BackgroundDuring the initial wave of COVID-19 hospitalizations, care delivery and workforce adaptations were rapidly implemented. In response to subsequent surges of patients, institutions have deployed, modified, and/or discontinued their workforce plans.ObjectiveUsing rapid qualitative methods, we sought to explore hospitalists’ experiences with workforce deployment, types of clinicians deployed, and challenges encountered with subsequent iterations of surge planning during the COVID-19 pandemic across a collaborative of hospital medicine groups.ApproachUsing rapid qualitative methods, focus groups were conducted in partnership with the Hospital Medicine Reengineering Network (HOMERuN). We interviewed physicians, advanced practice providers (APP), and physician researchers about (1) ongoing adaptations to the workforce as a result of the COVID-19 pandemic, (2) current struggles with workforce planning, and (3) evolution of workforce planning.Key ResultsWe conducted five focus groups with 33 individuals from 24 institutions, representing 52% of HOMERuN sites. A variety of adaptations was described by participants, some common across institutions and others specific to the institution’s location and context. Adaptations implemented shifted from the first waves of COVID patients to subsequent waves. Three global themes also emerged: (1) adaptability and comfort with dynamic change, (2) the importance of the unique hospitalist skillset for effective surge planning and redeployment, and (3) the lack of universal solutions.ConclusionsHospital workforce adaptations to the COVID pandemic continued to evolve. While few approaches were universally effective in managing surges of patients, and successful adaptations were highly context dependent, the ability to navigate a complex system, adaptability, and comfort in a chaotic, dynamic environment were themes considered most critical to successful surge management. However, resource constraints and sustained high workload levels raised issues of burnout.Supplementary InformationThe online version contains supplementary material available at 10.1007/s11606-022-07480-x.KEY WORDS: COVID-19, hospital medicine, workforce planning, surge planning, focus groups, qualitative     

Inherited thrombophilias and pre-eclampsia in Brazilian women

OBJECTIVE: The aim of the present study was to compare the distribution of G1691A, G20210A and C677T mutations in pre-eclamptic Brazilian women and in matched control women with an uncomplicated normal pregnancy. STUDY DESIGN: these mutations were investigated by PCR-RFLP in 83 normal pregnancies (control group) and in 30 pre-eclamptic pregnant women (severe form). RESULTS: G1691A mutation was detected neither in the control group nor in pre-eclamsia women. G20210A mutation was detected in heterozygosis in 3 (3.61%) control subjects, but not in pre-eclampsia group. C677T mutation was detected in homozygosis in 6 (7.23%) control subjects and 2 (6.67%) pre-eclamptic women and in heterozygosis in 31 (37.3%) control subjects and 12 (40%) pre-eclamptic women. Differences in the mutation frequencies detected in the two groups were not statistically significant. CONCLUSION: No correlation was observed between pre-eclampsia and presence of G1691A, G20210A and C677T mutations in Brazilian women.     

Preeclampsia: the role of tissue factor and tissue factor pathway inhibitor

Preeclampsia (PE) is a multi-system disorder of human pregnancy, whose etiology remains poorly understood. Preeclamptic women are known to have an increased hypercoagulable state that result in excess fibrin deposition in several organs, which compromises their function. Tissue factor (TF) is the main physiological initiator of blood coagulation and its activity is regulated by a specific inhibitor known as Tissue factor pathway inhibitor (TFPI). Based on the important role of TF and TFPI in hemostasis, we hypothesize that their levels may change in the severe PE contributing to exacerbate hypercoagulable state. Some studies have assessed the balance between TF and TFPI in preeclamptic women, but results are inconsistent. Therefore, the aim of this study was to examine these inconsistencies and to assess TF and TFPI plasma levels in three groups of age matched women; pregnant with severe PE (n = 60), normotensive pregnant (n = 50) and normotensive non-pregnant women (n = 50). There was not significantly different among the three groups for TF plasma levels; severe PE women: 338.4 pg/mL (248.1-457.6), normotensive pregnant women: 301.5 pg/mL (216.4-442.9) and normotensive non-pregnant women 393 pg/mL (310.3-522.9). TFPI plasma levels were higher in severe PE comparing to normotensive pregnant women and normotensive non-pregnant women, 115.8 ng/mL (75-149.8); 80.3 ng/mL (59.6-99.7) and 74.5 ng/mL (47.1-98.0), respectively No difference was found between normotensive pregnant women and normotensive non-pregnant women. As for gestational age, a significant difference in TFPI levels was found between severe PE and normotensive pregnant women up to the 33rd week of pregnancy (p = 0.001), and severe PE and non-pregnant women up to the 34th (p = 0.01). In summary, our results indicated that TF plasma levels did not vary in the studied groups, while TFPI plasma levels were significantly increased in severe PE compared to normotensive pregnant and normotensive non-pregnant women. So, our data do not explain the exacerbated hypercoagulability state observed in severe PE. Further studies evaluating genes expression, TF activity and antigen, total and free TFPI and TFPI-2, both in plasma and obstetric tissues, throughout the pregnancy in PE (mild and severe forms) are required.     

Efficacy of Breast Conservation Therapy in Early Stage Bilateral Breast Cancer

The purpose of this study was to evaluate the outcome of patients with bilateral breast cancer as compared to unilateral breast cancer treated with breast conservation therapy. Sixty patients with bilateral breast cancer (BBC) and 1,080 unilateral breast cancer (UBC) patients treated with breast conservation therapy from 1977 to 1994 were analyzed for outcome. Of the 60 bilateral patients, 44 were metachronous bilateral breast cancer patients (MBBC) and 16 were synchronous bilateral breast cancer patients (SBBC). The majority of patients received lumpectomy, axillary node dissection, and localized radiation therapy. Median tumor size was 1.4 cm for BBC and 1.5 cm for UBC patients. Median total dose to the tumor bed was 60 Gy for both unilateral and bilateral patients. Of the 44 MBBC patients, 14 received breast conservation for both the first and second lesions, while 30 received breast conservation for only the second metachronous lesion. Thus 58 lesions in 44 patients were treated with breast conservation therapy. Of the SBBC patients, 13 of 16 patients received breast-conserving therapy for both breasts, while 3 received a mastectomy for the second synchronous primary. Median follow-up was 50 months for SBBC patients, 45 months for MBBC patients, and 52 months for UBC patients. Local control and survival were analyzed in patients with SBBC, MBBC, and UBC. The interval to development of local recurrence and survival were calculated from the time of development of the second breast lesion in patients with MBBC. No differences were found for survival and failure-free survival in patients with SBBC, MBBC, or UBC. Five-year overall survival by lifetable analysis was 76% for SBBC, 78% for MBBC, and 87% for UBC patients (p = 0.32 by log-rank analysis). The 5-year failure-free survival was 79% for SBBC, 73% for MBBC, and 85% for UBC patients (p = 0.28 by log-rank analysis). No significant differences were seen for median age, tumor size, pathologic node status, tamoxifen use, chemotherapy use, or median total radiation dose for SBBC, MBBC, or UBC patients. A significant difference was found in the incidence of family history of breast cancer in patients with unilateral versus bilateral breast cancer (p = 0.028 by chi-square analysis). However, there was no difference in outcome of patients by family history of breast cancer. The local control was identical in both BBC and UBC patients, with a local failure rate of 3%. Therefore, breast conservation therapy in local-regional, early stage breast cancer is a rational and efficacious treatment modality for patients with SBBC, MBBC, and UBC.
