Cardiovascular Disease

<p>Abstract</p> <p>Health Issue</p> <p>Cardiovascular disease (CVD) is the leading cause of death in Canadian women and men. In general, women present with a wider range of symptoms, are more likely to delay seeking medial care and are less likely to be investigated and treated with evidence-based medications, angioplasty or coronary artery bypass graft than men.</p> <p>Key Findings</p> <p>In 1998, 78,964 Canadians died from CVD, almost half (39,197) were women. Acute myocardial infarction, which increases significantly after menopause, was the leading cause of death among women.</p> <p>Cardiovascular disease accounted for 21% of all hospital admissions for Canadian women over age 50 in 1999. Admissions to hospital for ischemic heart disease were more frequent for men, but the mean length of hospital stay was longer for women.</p> <p>Mean blood pressure increases with age in both men and women. After age 65, however, high blood pressure is more common among Canadian women. More than one-third of postmenopausal Canadian women have hypertension.</p> <p>Diabetes increases the mortality and morbidity associated with CVD in women more than it does in men. Depression also contributes to the incidence and recovery from CVD, particularly for women who experience twice the rate of depression as men.</p> <p>Data Gaps and Recommendations</p> <p>CVD needs to be recognized as a woman's health issue given Canadian mortality projections (particularly heart failure). Health professionals should be trained to screen, track, and address CVD risk factors among women, including hypertension, elevated lipid levels, smoking, physical inactivity, depression, diabetes and low socio-economic status.</p

Characteristics of Mid-Frequency Sensorineural Hearing Loss Progression.

OBJECTIVES:To characterize the progression of mid-frequency sensorineural hearing loss (MFSNHL) over time. METHODS:A retrospective chart review spanning 2012 to 2017 was performed at a tertiary care audiology and neurotology center. Our cohort included 37 patients met the criteria for MFSNHL also known as "cookie bite hearing loss." It was defined as having a 1, 2, and 4 kHz average pure tone audiometry greater than 10 dB in intensity compared with the average threshold at 500 Hz and 8 kHz. RESULTS:Average age at initial presentation was 11.8 years (range, 8 mo to 70 yr). Across all individuals, the average mid-frequency threshold was 47 dB, compared with 27 dB at 500 Hz and 8 kHz. Twenty-three patients (62%) had multiple audiograms with 4-year median follow up time. Average values across all frequencies (0.5, 1, 2, 4, 8 kHz) in the initial audiogram was 37 dB, compared with an average of 39 dB demonstrated on final audiogram. Of those with serial audiograms, only five patients demonstrated threshold changes of 10 dB or more. Of these five patients, only one was found to have clinical worsening of MFSNHL. CONCLUSIONS:MFSNHL is an uncommon audiometric finding with unspecified long-term outcomes. We demonstrated that most patients (96%) with MFSNHL do not experience clinical worsening of their hearing threshold over almost 4 years of follow up. Future prospective studies aimed at collecting longer-term data are warranted to further elucidate the long-term trajectory of MFSNHL patients

Women physicians and stress

Most women physicians enjoy better than average physical health and lead satisfying and productive lives. However, higher than average rates of depression, anxiety, marital problems, and substance abuse have been reported by some, but not all, authors. This quantitative survey of 196 women physicians and qualitative focus groups with 48 other women physicians was conducted to determine perceptions of their health, stress, satisfaction, knowledge, and abuse rates in medical practice. Eight specialties plus family practice physicians participated. The average age was 44.1 years (SD 8.8, range 23–77). Seventy-four percent of women physicians were married, with children. Specialists and family physicians were similar in all demographic characteristics except that family physicians were more significantly likely to be divorced, separated, or widowed (p ≤ 0.01). Specialists perceived their personal physical health to be better than that of family doctors (p ≤ 0.05), and family physicians rated their medical knowledge better than that of specialists (p ≤ 0.0001). Women physicians over age 50 or with children over age 19 reported the best mental health (p ≤ 0.0001 and 0.003, respectively). Overall, 49% of women physicians reported usually having high levels of stress, 44% felt mentally tired, and 17% took antidepressant drugs. Seventy-three percent reported verbal abuse at work (71% in the last year), and 33% reported physical assault at work (11% in the last year). Focus groups identified three major sources of stress: high expectations, multiple roles, and work environment. These results are discussed and compared with the literature. Both personal and systemic strategies are required to solve the problems identified. Women physicians can facilitate the adoption of some of these strategies by sharing information about successes, challenges, and solutions

Branchiootorenal syndrome and oculoauriculovertebral spectrum features associated with duplication of SIX1 , SIX6 , and OTX2 resulting from a complex chromosomal rearrangement

We report on a 26-month-old boy with developmental delay and multiple congenital anomalies, including many features suggestive of either branchiootorenal syndrome (BOR) or oculoauriculovertebral spectrum (OAVS). Chromosomal microarray analysis (CMA) initially revealed a copy-number gain with a single BAC clone (RP11-79M1) mapping to 14q23.1. FISH analysis showed that the third copy of this genomic region was inserted into the long arm of one chromosome 13. The same pattern was also seen in the chromosomes of the father, who has mental retardation, short stature, hypernasal speech, and minor craniofacial anomalies, including tall forehead, and crowded dentition. Subsequent whole genome oligonucleotide microarray analysis revealed an ∼11.79 Mb duplication of chromosome 14q22.3–q23.3 and a loss of an ∼4.38 Mb sequence in 13q21.31–q21.32 in both the propositus and his father and FISH supported the apparent association of the two events. Chromosome 14q22.3–q23.3 contains 51 genes, including SIX1 , SIX6 , and OTX2 . A locus for branchiootic syndrome (BOS) has been mapped to 14q21.3–q24.3, and designated as branchiootic syndrome 3 (BOS3). Interestingly, mutations in SIX1 have been reported in patients with BOR/BOS3. We propose that the increased dosage of SIX1 , SIX6 , or OTX2 may be responsible for the BOR and OAVS-like features in this family. © 2008 Wiley-Liss, Inc.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/60991/1/32398_ftp.pd

Deletions in chromosome 6p22.3-p24.3, including ATXN1, are associated with developmental delay and autism spectrum disorders

Interstitial deletions of the short arm of chromosome 6 are rare and have been associated with developmental delay, hypotonia, congenital anomalies, and dysmorphic features. We used array comparative genomic hybridization in a South Carolina Autism Project (SCAP) cohort of 97 subjects with autism spectrum disorders (ASDs) and identified an ~ 5.4 Mb deletion on chromosome 6p22.3-p23 in a 15-year-old patient with intellectual disability and ASDs. Subsequent database queries revealed five additional individuals with overlapping submicroscopic deletions and presenting with developmental and speech delay, seizures, behavioral abnormalities, heart defects, and dysmorphic features. The deletion found in the SCAP patient harbors ATXN1, DTNBP1, JARID2, and NHLRC1 that we propose may be responsible for ASDs and developmental delay

Design and validation of the Health Professionals' Attitudes Toward the Homeless Inventory (HPATHI)

BACKGROUND: Recent literature has called for humanistic care of patients and for medical schools to begin incorporating humanism into medical education. To assess the attitudes of health-care professionals toward homeless patients and to demonstrate how those attitudes might impact optimal care, we developed and validated a new survey instrument, the Health Professional Attitudes Toward the Homeless Inventory (HPATHI). An instrument that measures providers' attitudes toward the homeless could offer meaningful information for the design and implementation of educational activities that foster more compassionate homeless health care. Our intention was to describe the process of designing and validating the new instrument and to discuss the usefulness of the instrument for assessing the impact of educational experiences that involve working directly with the homeless on the attitudes, interest, and confidence of medical students and other health-care professionals. METHODS: The study consisted of three phases: identifying items for the instrument; pilot testing the initial instrument with a group of 72 third-year medical students; and modifying and administering the instrument in its revised form to 160 health-care professionals and third-year medical students. The instrument was analyzed for reliability and validity throughout the process. RESULTS: A 19-item version of the HPATHI had good internal consistency with a Cronbach's alpha of 0.88 and a test-retest reliability coefficient of 0.69. The HPATHI showed good concurrent validity, and respondents with more than one year of experience with homeless patients scored significantly higher than did those with less experience. Factor analysis yielded three subscales: Personal Advocacy, Social Advocacy, and Cynicism. CONCLUSIONS: The HPATHI demonstrated strong reliability for the total scale and satisfactory test-retest reliability. Extreme group comparisons suggested that experience with the homeless rather than medical training itself could affect health-care professionals' attitudes toward the homeless. This could have implications for the evaluation of medical school curricula

Genomic and Genic Deletions of the FOX Gene Cluster on 16q24.1 and Inactivating Mutations of FOXF1 Cause Alveolar Capillary Dysplasia and Other Malformations

Alveolar capillary dysplasia with misalignment of pulmonary veins (ACD/MPV) is a rare, neonatally lethal developmental disorder of the lung with defining histologic abnormalities typically associated with multiple congenital anomalies (MCA). Using array CGH analysis, we have identified six overlapping microdeletions encompassing the FOX transcription factor gene cluster in chromosome 16q24.1q24.2 in patients with ACD/MPV and MCA. Subsequently, we have identified four different heterozygous mutations (frameshift, nonsense, and no-stop) in the candidate FOXF1 gene in unrelated patients with sporadic ACD/MPV and MCA. Custom-designed, high-resolution microarray analysis of additional ACD/MPV samples revealed one microdeletion harboring FOXF1 and two distinct microdeletions upstream of FOXF1, implicating a position effect. DNA sequence analysis revealed that in six of nine deletions, both breakpoints occurred in the portions of Alu elements showing eight to 43 base pairs of perfect microhomology, suggesting replication error Microhomology-Mediated Break-Induced Replication (MMBIR)/Fork Stalling and Template Switching (FoSTeS) as a mechanism of their formation. In contrast to the association of point mutations in FOXF1 with bowel malrotation, microdeletions of FOXF1 were associated with hypoplastic left heart syndrome and gastrointestinal atresias, probably due to haploinsufficiency for the neighboring FOXC2 and FOXL1 genes. These differences reveal the phenotypic consequences of gene alterations in cis
