The role of inflammatory and parenchymal cells in acute pancreatitis

The infiltration of inflammatory cells into the pancreas is an early and central event in acute pancreatitis that promotes local injury and systemic complications of the disease. Recent research has yielded the important finding that resident cells of the pancreas (particularly acinar and pancreatic stellate cells) play a dynamic role in leukocyte attraction via secretion of chemokines and cytokines and expression of adhesion molecules. Significant progress has been made in recent years in our understanding of the role of leukocyte movement (adhesion to the blood vessel wall, transmigration through the blood vessel wall and infiltration into the parenchyma) in the pathophysiology of acute pancreatitis. This review discusses recent studies and describes the current state of knowledge in the field. It is clear that detailed elucidation of the numerous processes in the inflammatory cascade is an essential step towards the development of improved therapeutic strategies in acute pancreatitis. Studies to date suggest that combination therapy targeting different steps of the inflammatory cascade may be the treatment of choice for this disease.     

Fetal and Infant Growth Patterns and Kidney Function at School Age

Low birth weight is associated with ESRD. To identify specific growth patterns in early life that may be related to kidney function in later life, we examined the associations of longitudinally measured fetal and infant growth with kidney function in school-aged children. This study was embedded in a population-based prospective cohort study among 6482 children followed from fetal life onward. Fetal and childhood growth was measured during second and third trimesters of pregnancy, at birth, and at 6, 12, 24, 36, and 48 months postnatally. At the age of 6 years, we measured kidney volume by ultrasound. GFR was estimated using blood creatinine levels. Higher gestational age-adjusted birth weight was associated with higher combined kidney volume and higher eGFR (per 1 SD score increase in birth weight; 1.27 cm³ [95% confidence interval, 0.61 to 1.93] and 0.78 ml/min per 1.73 m² [95% CI, 0.16 to 1.39], respectively). Fetal weight, birth weight, and weight at 6 months were positively associated with childhood kidney volume, whereas higher second trimester fetal weight was positively associated with higher GFR (all P values<0.05). Fetal and childhood lengths were not consistently associated with kidney function. In this cohort, lower fetal and early infant weight growth is associated with smaller kidney volume in childhood, whereas only lower fetal weight growth is associated with lower kidney function in childhood, independent of childhood growth. Whether these associations lead to an increased risk of kidney disease needs to be studied further.Low birth weight is associated with higher risks of ESRD and hypertension in later life.^1–3 Clearly, low birth weight is not the causal factor per se leading to kidney diseases in later life. Birth weight is the result of various exposures and growth patterns in fetal life and the starting point of childhood growth. It has been hypothesized that especially third trimester fetal growth restriction leads to persistently smaller kidneys with a reduced number of nephrons, which may predispose the individual to kidney disease in adulthood.^4–6 This hypothesis is supported by both animal and human studies, showing that kidney volume and nephron number are reduced in fetal growth-restricted subjects and hypertensive subjects.^7–9 Although nephrogenesis is known to continue until 36 weeks of gestation and cease thereafter, not much is known about the specific critical periods and early growth patterns related to kidney function in later life.¹⁰ Also, whether and to what extent the associations of low birth weight with CKD are explained by preterm birth are not known.¹ Longitudinal studies suggested that the associations of low birth weight with hypertension were stronger in subjects with rapid weight gain in childhood, but results are inconclusive.^11,12 A similar growth pattern has not been identified as a risk factor for kidney diseases yet.Prospective studies linking fetal and early childhood growth patterns to kidney outcomes in later life might help to identify early critical periods for developing impaired kidney function in later life.Therefore, we examined, in a population-based prospective cohort study among 6482 children followed from early fetal life onward (Figure 1), the associations of birth weight, gestational age, birth weight for gestational age, and longitudinally measured fetal and early childhood growth patterns with kidney size and function at school age. We used subclinical variations of kidney function in childhood as outcomes, because they relate to kidney disease in later life.¹³Open in a separate windowFigure 1.Flow chart: exclusion criteria and numbers of participants are given.

Effects of yoga on cardiovascular disease risk factors: A systematic review and meta-analysis

Background

The aim of this review was to systematically assess and meta-analyze the effects of yoga on modifiable biological cardiovascular disease risk factors in the general population and in high-risk disease groups.

Methods

MEDLINE/PubMed, Scopus, the Cochrane Library, and IndMED were screened through August 2013 for randomized controlled trials (RCTs) on yoga for predefined cardiovascular risk factors in healthy participants, non-diabetic participants with high risk for cardiovascular disease, or participants with type 2 diabetes mellitus. Risk of bias was assessed using the Cochrane risk of bias tool.

Results

Forty-four RCTs with a total of 3168 participants were included. Risk of bias was high or unclear for most RCTs. Relative to usual care or no intervention, yoga improved systolic (mean difference (MD) = − 5.85 mm Hg; 95% confidence interval (CI) = − 8.81, − 2.89) and diastolic blood pressure (MD = − 4.12 mm Hg; 95%CI = − 6.55, − 1.69), heart rate (MD = − 6.59 bpm; 95%CI = − 12.89, − 0.28), respiratory rate (MD = − 0.93 breaths/min; 95%CI = − 1.70, − 0.15), waist circumference (MD = − 1.95 cm; 95%CI = − 3.01, − 0.89), waist/hip ratio (MD = − 0.02; 95%CI = − 0.03, − 0.00), total cholesterol (MD = − 13.09 mg/dl; 95%CI = − 19.60, − 6.59), HDL (MD = 2.94 mg/dl; 95%CI = 0.57, 5.31), VLDL (MD = − 5.70 mg/dl; 95%CI = − 7.36, − 4.03), triglycerides (MD = − 20.97 mg/dl; 95%CI = − 28.61, − 13.32), HbA1c (MD = − 0.45%; 95%CI = − 0.87, − 0.02), and insulin resistance (MD = − 0.19; 95%CI = − 0.30, − 0.08). Relative to exercise, yoga improved HDL (MD = 3.70 mg/dl; 95%CI = 1.14, 6.26).

Conclusions

This meta-analysis revealed evidence for clinically important effects of yoga on most biological cardiovascular disease risk factors. Despite methodological drawbacks of the included studies, yoga can be considered as an ancillary intervention for the general population and for patients with increased risk of cardiovascular disease.     

Psychological interventions for depression and anxiety in pregnant Latina and Black women in the United States: A systematic review

Black women and Latinas have more symptoms of depression and anxiety during pregnancy than do their non‐Latina White counterparts. Although effective interventions targeting internalizing disorders in pregnancy are available, they are primarily tested with White women. This article reviews randomized controlled trials and non‐randomized studies to better understand the effectiveness of psychological interventions for anxiety and depression during pregnancy in Latinas and Black women. Additionally, this review summarizes important characteristics of interventions such as intervention format, treatment modality, and the use of cultural adaptations. Literature searches of relevant research citation databases produced 68 studies; 13 of which were included in the final review. Most studies were excluded because their samples were not majority Latina or Black women or because they did not test an intervention. Of the included studies, three interventions outperformed a control group condition and showed statistically significant reductions in depressive symptoms. An additional two studies showed reductions in depressive symptoms from pretreatment to post‐treatment using non‐controlled designs. The remaining eight studies (seven randomized and one non‐randomized) did not show significant intervention effects. Cognitive behavioral therapy was the modality with most evidence for reducing depressive symptoms in pregnant Black and Latina women. No intervention was found to reduce anxiety symptoms, although only two of the 13 measured anxiety as an outcome. Five studies made cultural adaptations to their treatment protocols. Future studies should strive to better understand the importance of cultural modifications to improve engagement and clinical outcomes with pregnant women receiving treatment for anxiety and depression.     

Predictors of Health Behavior Change After an Integrative Medicine Inpatient Program

Background

Health behavior change can improve physical and psychosocial outcomes in internal medicine patients.

Purpose

This study aims to identify predictors for health behavior change after an integrative medicine inpatient program.

Method

German internal medicine patients' (N?=?2,486; 80 % female; 53.9?±?14.3 years) practice frequency for aerobic exercise (e.g., walking, running, cycling, swimming), meditative movement therapies (e.g., yoga, tai ji, qigong), and relaxation techniques (e.g., progressive relaxation, mindfulness meditation, breathing exercises, guided imagery) was assessed at admission to a 14-day integrative medicine inpatient program, and 3, 6, and 12 months after discharge. Health behavior change was regressed to exercise self-efficacy, stage of change, and health locus of control (internal, external-social, external-fatalistic).

Results

Short-term increases in practice frequency were found for aerobic exercise: short- and long-term increases for meditative movement therapies and relaxation techniques (all p?p?p?Conclusion Health behavior change after an integrative medicine inpatient program was predicted by self-efficacy, stage of change, and health locus of control. Considering these aspects might improve adherence to health-promoting behavior after lifestyle modification programs.     

An integrative review on family caregivers’ involvement in care of home‐dwelling elderly

Often family members provide care‐giving, which allows older adults to remain in their homes. With declining health and increasing frailty, care‐giving of elderly people becomes a task of family caregivers (FC) in conjunction with home care nurses. It has been shown in both acute care settings and long‐term care facilities that family members prefer to be involved in decision‐making and care planning for their next of kin. Therefore, an integrative review was conducted to explore the body of knowledge of FCs’ involvement in home‐care settings from the FCs’ perspective. CINAHL, PubMed, and Cochrane databases was searched with the terms family caregiver, involvement, home care, and community dwelling. Studies written in German or English between 1996 and 2017 focusing on FCs’ caring for home‐dwelling older adults together with home care nurses were included and critically appraised. The extracted findings were analysed with concept analysis method. Twenty‐six studies were included and five themes were identified. Four themes formed the basis of assistance towards family caregivers by nurses and included “relationship building with professionals,” “negotiating with professional care,” “being professionally supported,” and “managing role expectations and knowledge sharing”. The fifth theme, “working together” described the mutual care for the care recipient. Although the first four themes were consistent with a pre‐existing conceptual model by Sims‐Gould and Marin‐Matthews (2010), the fifth required an expansion of the model with an additional contribution “collaborative practice”. The findings illustrate that involvement in care is an interactional process, which provides the basis for collaborative practices with the home care nurses for family caregivers. Family members often want to be part of the healthcare team, and nurses need contextual factors that allow providing their full range of skills and knowledge to involve family caregivers accordingly.
