Systematic review and meta-analysis of preterm birth and later systolic blood pressure

Lower birth weight because of fetal growth restriction is associated with higher blood pressure later in life, but the extent to which preterm birth (<37 completed weeks' gestation) or very low birth weight (<1500 g) predicts higher blood pressure is less clear. We performed a systematic review of 27 observational studies that compared the resting or ambulatory systolic blood pressure or diagnosis of hypertension among children, adolescents, and adults born preterm or very low birth weight with those born at term. We performed a meta-analysis with the subset of 10 studies that reported the resting systolic blood pressure difference in millimeters of mercury with 95% CIs or SEs. We assessed methodologic quality with a modified Newcastle-Ottawa Scale. The 10 studies were composed of 1342 preterm or very low birth weight and 1738 term participants from 8 countries. The mean gestational age at birth of the preterm participants was 30.2 weeks (range: 28.8-34.1 weeks), birth weight was 1280 g (range: 1098-1958 g), and age at systolic blood pressure measurement was 17.8 years (range: 6.3-22.4 years). Former preterm or very low birth weight infants had higher systolic blood pressure than term infants (pooled estimate: 2.5 mm Hg [95% CI: 1.7-3.3 mm Hg]). For the 5 highest quality studies, the systolic blood pressure difference was slightly greater, at 3.8 mm Hg (95% CI: 2.6-5.0 mm Hg). We conclude that infants who are born preterm or very low birth weight have modestly higher systolic blood pressure later in life and may be at increased risk for developing hypertension and its sequelae.     

Indications for and results of arthroscopy in the arthritic knee: a European survey

Purpose

The place of arthroscopic treatment in osteoarthritis of the knee has generated much controversy. A survey was initiated to collect the opinion of experienced surgeons.

Methods

Of the 211 surgeons interviewed, 170 (80.6 %) replied to the electronic questionnaire. Respondents had at least ten years of experience in arthroscopy and currently perform more than 100 arthroscopies per year. Various indications and treatment modalities for arthroscopy in osteoarthritis of the knee had to be evaluated on a scale from “excellent” to “no indication”.

Results

The respondents generally believe that an improvement is more likely in low-grade osteoarthritis (p < 0.001) and in neutral leg axis (p < 0.001). The outcome was rated better if symptoms had persisted for less than six months (p < 0.001) and for patients that were younger than 60 years (p < 0.001). Partial meniscectomy and notchplasty in cases of extension deficit were considered as successful treatment options. Debridement was an accepted indication, with an outcome mainly rated as fair. A majority saw no indication for joint lavage, arthroscopic treatment of arthrofibrosis and removal of osteophytes. The outcome appears to be poor if a bone edema is diagnosed on magnetic resonance imaging prior to arthroscopy. Only 55.9 % of respondents were comfortable with the current definition of osteoarthritis.

Conclusions

Experienced arthroscopic surgeons all over Europe believe arthroscopy in osteoarthritis is appropriate, under certain conditions. The major task for surgeons is to select the right patients who are likely to benefit from this intervention.     

Family Dinner and Disordered Eating Behaviors in a Large Cohort of Adolescents

We aimed to examine longitudinal associations between family dinner and disordered eating behaviors among adolescents. We studied 7535 females and 5913 males, 9 to 14 years of age in 1996. We performed multivariable logistic regression to assess the associations of previous year family dinner with 1-year incidence of each of 3 outcomes: purging, binge eating, and frequent dieting. Compared to those who ate family dinner “never or some days,” female adolescents who ate family dinner at least most days were less likely to initiate purging, binge eating, and frequent dieting. Estimates of association among males were similar in direction and magnitude, although lower frequency of the outcomes resulted in less precise estimates and fewer statistically significant results.     

Stronger together: midwifery twinning between Tanzania and Canada

This article describes a twinning relationship between the Canadian Association of Midwives (CAM) and the Tanzania Midwives Association (TAMA). It argues that the twinning relationship strengthened both associations. The article briefly reviews the existing literature on professional associations and association strengthening to demonstrate that professional associations are a vital tool for improving the performance of healthcare workers and increasing their capacity to contribute to national and international policy-making. It then suggests that midwifery associations are particularly significant given the frequent professional marginalization of midwives. The article then describes in depth the relationship between CAM and TAMA, highlighting the accomplishments of the twinned partners, and analyzing the factors that contributed to the success of the relationship. The findings demonstrate that twinning can successfully strengthen associations, increasing their ability to support their membership, care for the public, and shape national policy-making. The article therefore proposes twinning as a successful and cost-effective model for encouraging the growth of the midwifery profession.     

Verhaltensprävention im betrieblichen Setting

Background

The office routine of many employees restrains physical activity and is full of one-sided work-load and stressful cognitive events. Tension in neck and shoulder, back pain, headaches, fatigue, difficulties in concentrating, skin and gastrointestinal problems may result. In order to contribute to employee’s physical and mental well-being, a 15-minute work-place activity program (“Break in Motion”) was implemented in the Schwäbisch Gmünd plant of ZF Lenksysteme.

Method

To assess whether “Break in Motion” reduces physical complaints, adds to subjective well-being and improves the working atmosphere, a longitudinal study was carried out. Written questionnaires were utilize before and after the intervention to screen possible effects (n?=?68 and 79).

Results

Comparison of means revealed reduction in health problems in the neck, the back and the shoulder and the dorsal spine area. Improved subjective well-being was statistically significant only for female participants. Almost all participants stated that the activity program strengthens social cohesion on the work floor.

Conclusion

The results suggest that, if regularly conducted, even a relatively short and as such amendable to the work-place demands and moreover demonstrably scalable exercise and activity program shows positive effects.     

GI Symptoms in Infants Are a Potential Target for Fermented Infant Milk Formulae: A Review

Besides pre- and pro-biotic-containing infant formulae, fermented infant formulae are commonly used to relieve or prevent symptoms of gastrointestinal (GI) discomfort in young infants. During the fermentation process in cow’s milk-based formulae, the beneficial bacteria modulate the product by forming several beneficial compounds, which contribute to the alleviation of the symptoms observed. This review summarizes the clinical evidence on the impact of fermented infant formulae on common pediatric GI-symptoms. The potential mechanisms involved are discussed: i.e., the lactose and protein (in-) digestibility, effects on gastric emptying and gut transit and modulation of the colonic microbiota. Although initial evidence indicates a beneficial effect of fermented formulae on GI discomfort in newborns, validation and confirmation of the clinical proof obtained so far is warranted, as well as further research to (more fully) understand the mode of action.
