Assessment of cardiovascular risk and social framework of Cape Verdean university students studying in Portugal

Introduction

The migration of African populations to Europe poses problems of adaptation that may increase the risk of cardiovascular disease. We assessed the cardiovascular risk of Cape Verdean university students studying in Portugal (CV-PT) compared to Cape Verdean university students in Cape Verde (CV-CV) and to Caucasian university students in Portugal (PT-PT).

Long-term survival in pulmonary arterial hypertension and chronic thromboembolic pulmonary hypertension: Insights from a referral center in Portugal

Objectives

This study aims to assess the long-term survival of pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH) patients followed in a Portuguese pulmonary hypertension (PH) referral center.

Pudendal nerve terminal motor latency testing does not provide useful information in guiding therapy for fecal incontinence

Purpose

Pudendal nerve terminal motor latency (PNTML) testing is a standard recommendation for the evaluation of fecal incontinence. Its role in guiding therapy for fecal incontinence has been previously questioned. The aim of this study was to evaluate the relationship between PNTML testing and anorectal dysfunction.

Methods

This was a retrospective analysis of data collected prospectively from patients who presented to a pelvic floor disorder center from 2007 to 2015. The relationship between PNTML (normal versus delayed) and anorectal manometry, fecal incontinence severity, and fecal incontinence-related quality of life scores was assessed using the Wilcoxon-Mann-Whitney test.

Results

Two hundred sixty-nine patients underwent PNTML testing, and 91.1% were female (N?=?245) (median age 62.2 years). Normal PNTML was seen in 234 (87.0%) patients. Among 268 patients who underwent anorectal manometry, delayed PNTML was only significantly associated with median maximum anal squeeze pressure (P?=?0.04). Delayed PNTML was not associated with a decrease in median fecal incontinence severity or fecal incontinence-related quality of life scores (N?=?99).

Conclusions

PNTML was only associated with median maximum anal squeeze pressure, and it was not associated with patient-reported severity of symptoms of fecal incontinence, changes in quality of life attributable to fecal incontinence, median mean resting anal pressure, or median maximum resting anal pressure. PNTML testing may not be relevant to current therapeutic algorithms for fecal incontinence and its routine use should be questioned.

     

Late assessment of quality of life in patients with rectal carcinoma: comparison between sphincter preservation and definitive colostomy

Purpose

Patients with cancer of the lower and middle rectum who are candidates for curative surgery often have negative opinions on definitive colostomy. The purpose of this study is to compare the quality of life (QoL) of patients who undergo standard treatment for rectal cancer with sphincter preservation or definitive colostomy.

Methods

A total of 125 patients with adenocarcinoma of the lower or middle rectum who underwent radical surgery with curative intent with a follow-up ≥?1 year were recruited: 83 patients (group 1) were subjected to low anterior resection and low colorectal or coloanal anastomosis—thus preserving their sphincter—and 42 (group 2) were treated with abdominoperineal resection, followed by terminal definitive colostomy. QoL was assessed with the EORTC QLQ-C30 and QLQ-CR29 questionnaires.

Results

Health and global quality of life were similar between groups; however, patients who underwent definitive colostomy had higher scores on the emotional (p value?=?0.016) and cognitive function scales (p value?=?0.017). Patients with sphincter preservation presented with more symptoms that were related to stool frequency (p value <?0.001), intestinal constipation (p value?=?0.005), fecal incontinence (p value?=?0.001), buttock pain (p value?=?0.023), and nausea and vomiting (p value?=?0.036), whereas patients with permanent colostomy had higher scores for dysuria (p value?=?0.033).

Conclusion

Although global QoL scores did not differ between groups, patients who underwent definitive colostomy had significantly better functional and symptom scale scores, reflecting greater function with fewer symptoms.

     

Migraines, angiographic coronary artery disease and cardiovascular outcomes in women

Purpose

There are conflicting data regarding the association between migraines and cardiovascular events. We evaluated the relationship between migraine headaches, angiographic coronary artery disease, and cardiovascular events in women.

Subjects and Methods

The Women’s Ischemia Syndrome Evaluation (WISE) study is a National Heart, Lung and Blood Institute (NHLBI)-sponsored prospective, multicenter study aiming to improve ischemia evaluation in women. A total of 944 women presenting with chest pain or symptoms suggestive of myocardial ischemia were enrolled and underwent complete demographic, medical, and psychosocial history, physical examination, and coronary angiography testing. A smaller subset of 905 women, representing a mean age of 58 years, answered questions regarding a history of migraines. We prospectively followed 873 women for 4.4 years for cardiovascular events and all-cause mortality.

Results

Women reporting a history of migraines (n = 220) had lower angiographic coronary severity scores, and less severe (≥ 70% luminal stenosis) angiographic coronary artery disease compared to women without a history of migraines (n = 685). These differences remained statistically significant after adjustment for age and other important cardiac risk factors. On prospective follow-up of a median of 4.4 years, women with a history of migraines were not more likely to have a cardiovascular event (hazard ratio [HR] 1.2; 95% confidence interal [CI], 0.93-1.58) and migraines did not predict all-cause mortality (HR 0.96; 95% CI, 0.49-1.99).

Conclusion

Among women undergoing coronary angiography for suspected ischemia, those reporting migraines had less severe angiographic coronary artery disease. We could not support an association between migraines and cardiovascular events or death. Further research studying the common pathophysiology underlying migraines and cardiovascular disease is warranted.     

Rapid onset of transmission-reducing antibodies in javanese migrants exposed to malaria in papua, indonesia

Transmission of Plasmodium falciparum malaria is initiated by sexual stages in the mosquito. Anti-Pfs48/45 and anti-Pfs230 sexual stage antibodies that are ingested together with parasites can reduce parasite development and subsequently malaria transmission. Acquisition of sexual stage immunity was studied in a cohort of 102 non-immune Javanese individuals migrating to hyperendemic Papua Indonesia. Seroprevalence of antibodies against Pfs48/45 and Pfs230 and functional transmission-reducing activity (TRA) were measured upon arrival and at 6, 12, and 24 months. Asexual parasitemia and gametocytemia were assessed every two weeks. The TRA and seroreactivity increased with the number of P. falciparum infections. The longitudinally sustained association between TRA and antibodies against Pfs48/45 (odds ratio [OR] = 3.74, 95% confidence interval [CI] = 1.51-9.29) and Pfs230 (OR = 3.72, 95% CI = 1.36-10.17) suggests that functional transmission reducing immunity is acquired after limited exposure to infection.     

Loss of circulating CD27+ memory B cells and CCR4+ T cells occurring in association with elevated EBV loads in XLP patients surviving primary EBV infection

Detailed longitudinal studies of patients with X-linked lymphoproliferative disease (XLP) may increase our understanding of the immunologic defects that contribute to the development of lymphoma and hypogammaglobulinemia in XLP. We describe progressive changes observed in immunoglobulin concentrations, lymphocyte subsets, and Epstein-Barr virus (EBV) loads occurring in a 2-year period in a newly infected, but otherwise healthy, carrier (patient 9). We compare these findings with those observed in the patient's brother, who had hypogammaglobulinemia and XLP (patient 4). Immunoglobulin G (IgG), IgM, and IgA concentrations increased in patient 9 during acute EBV infection, but thereafter they decreased steadily to concentrations consistent with hypogammaglobulinemia, reaching a plateau 5 months after infection. In both patients, CD19+ B-lymphocyte rates remained lower than 3%, with a contraction of the B-cell memory compartment (CD27+ CD19+/CD19+) to 20% (normal range, 32%-56%). T-lymphocyte subpopulations showed a reduction in CD4+ T-cell counts and a permanent CD8+ T-cell expansion. Interestingly, CXCR3 memory TH1 cells were expanded and CCR4+ TH2 lymphocytes were reduced, suggesting that abnormal skewing of memory T-cell subsets might contribute to reduced antibody synthesis. Despite an expanded number of CD3+CD8+ lymphocytes, increased EBV loads occurred in both patients without overt clinical symptoms of mononucleosis, lymphoproliferative disease, or lymphoma.     

Cytomegalovirus (CMV)-encoded UL144 (truncated tumor necrosis factor receptor) and outcome of congenital CMV infection

BACKGROUND: Cytomegalovirus (CMV) is the most common congenital infection in humans. The effect of viral strains on the outcome of congenital CMV is debated. We evaluated whether UL144 polymorphisms in amniotic fluid from CMV-infected Italian women were associated with terminations of pregnancy, subsequent disease in their offspring, or viral load. METHODS: The study was nested within a prenatal CMV program. We sequenced the UL144 gene from 66 amniotic-fluid samples, without knowledge of pregnancy outcome. We performed data analyses on 56 samples for which all information was available. RESULTS: Genotype C was associated with termination of pregnancy (P=.03). Genotype B was associated with fewer terminations of pregnancy (P=.003). A possible association was found between genotype C and symptomatic disease in newborns (odds ratio, 8.81 [95% confidence interval, 0.48-164.02]; P=.05). There was no association between specific genotype and the viral load in amniotic fluid. Symptomatic newborns who had the most common UL144 genotype (B) were more likely to have higher viral loads than were asymptomatic infants (P=.003). CONCLUSIONS: UL144 polymorphisms may be associated with the outcome of congenital CMV infection. Larger studies should be conducted to confirm this association, before genotype analysis can be used, along with other factors, in considering terminations of pregnancy.
