Nutrition in adolescent growth and development.

During adolescence, growth and development are transformative and have profound consequences on an individual's health in later life, as well as the health of any potential children. The current generation of adolescents is growing up at a time of unprecedented change in food environments, whereby nutritional problems of micronutrient deficiency and food insecurity persist, and overweight and obesity are burgeoning. In a context of pervasive policy neglect, research on nutrition during adolescence specifically has been underinvested, compared with such research in other age groups, which has inhibited the development of adolescent-responsive nutritional policies. One consequence has been the absence of an integrated perspective on adolescent growth and development, and the role that nutrition plays. Through late childhood and early adolescence, nutrition has a formative role in the timing and pattern of puberty, with consequences for adult height, muscle, and fat mass accrual, as well as risk of non-communicable diseases in later life. Nutritional effects in adolescent development extend beyond musculoskeletal growth, to cardiorespiratory fitness, neurodevelopment, and immunity. High rates of early adolescent pregnancy in many countries continue to jeopardise the growth and nutrition of female adolescents, with consequences that extend to the next generation. Adolescence is a nutrition-sensitive phase for growth, in which the benefits of good nutrition extend to many other physiological systems.

Eliminating malaria in conflict zones: public health strategies developed in the Sri Lanka Civil War.

Despite the 26-year long civil war, Sri Lanka was declared malaria-free by WHO in 2016. This achievement was the result of nearly 30 years of elimination efforts following the last significant resurgence of malaria cases in Sri Lanka. The resurgence occurred in 1986-1987, when about 600 000 cases of malaria were detected. Obstacles to these efforts included a lack of healthcare workers in conflict zones, a disruption of vector control efforts, gaps in the medication supply chain, and rising malaria cases among the displaced population.This article seeks to describe the four strategies deployed in Sri Lanka to mitigate the aforementioned obstacles to ultimately achieve malaria elimination. The first approach was the support for disease elimination by the government of Sri Lanka and the Liberation Tamil Tigers of Elam. The second strategy was the balance of centralised leadership of the federal government and the decentralised programme operation at the regional level. The third strategy was the engagement of non-governmental stakeholders to fill in gaps left by the conflict to continue the elimination efforts. The last strategy is the ongoing efforts by the government, military and non-profit organisations to prevent the reintroduction of malaria.The lessons learnt from Sri Lanka have important implications for malaria-endemic nations that are in conflict such as Ethiopia, Afghanistan, Yemen and Somalia. To accomplish the World Health Assembly goal of reducing the global incidence and mortality of malaria by 90% by 2030, significant efforts are required to lessen the disease burden in conflict zones. In addition to the direct impacts of conflict on population health, conflicts may lead to increased risk of spread of malaria, both within a country and consequently, abroad.

Evaluating and implementing an opportunity for diversity and inclusion in case-based learning.

Problem-based learning (PBL) and case-based learning (CBL) often mention social identities only if this information is directly relevant to diagnosis, which can inadvertently perpetuate stereotypes in trainee learning. Using a student-developed resource entitled "Portraying Social Identities in Medical Curriculum: A Primer," we analyzed cases for social identities, identified gaps, and proposed changes, including use of a validated name bank to reflect diversity as represented by local census data. Through this innovation, suggestions were provided to represent the social determinants of health in CBL cases. Other medical schools can use our innovation to improve the social diversity of their medical curriculums.

Bien souvent, l'apprentissage par résolution de problèmes (ARP) et l'apprentissage par les cas (APC) ne touchent aux identités sociales que si ce type d'information contribue directement au diagnostic, ce qui peut involontairement perpétuer les stéréotypes dans l'apprentissage des étudiants. À l'aide d'une ressource élaborée par les étudiants, intitulée « Portraying Social Identities in Medical Curriculum : A Primer ¼ (la représentation des identités sociales dans les programmes d'études médicales : une introduction), nous avons analysé des cas d'identités sociales, identifié des lacunes et proposé des changements, notamment l'utilisation d'une banque de noms validée reflétant la diversité qui ressort des données du recensement local. Grâce à cette innovation, des suggestions ont été faites pour représenter les déterminants sociaux de la santé dans les cas étudiés dans l'APC. Nous invitons les facultés de médecine à se servir de notre ressource pour mieux rendre compte de la diversité sociale dans leurs programmes d'études.

The interrelation between lipid profile in chronic HCV patients and their response to antiviral agents.

OBJECTIVES: This study aims to assess the changes of lipid profile in chronic HCV patients; before, during, and after treatment with DAAs and their association with treatment response. METHODS: 301 chronic HCV patients who received SOF-based therapy were included. Serum lipid profile was assessed at different check points; baseline, 6 weeks on treatment, end of treatment (EOT) and 12 weeks after EOT; and compared between SVR and non-SVR groups. RESULTS: SVR group had significantly higher baseline lipid parameters compared to non-SVR group with significant increase in lipid parameters at different time points apart from HDL-C. Non-SVR group showed non-significant change in lipid parameters apart from LDL-C. On week6 on treatment, cholesterol level > 125 mg/dl was 92.8% sensitive, 97.3% specific with 95.5% NPV, and AUC of 0.989 in prediction of SVR. Similarly, LDL > 57 mg/dl was 83.7% sensitive, 100% specific with 93.3%, NPV and AUC of 0.952. Baseline cholesterol and LDL were significantly associated with SVR. CONCLUSION: Higher baseline lipid parameters and their further elevation starting from week 6 on treatment are good predictors of SVR in HCV patients. Successful HCV therapy with DAAs is associated with a significant increase in lipid parameters.

High Serum Endothelin-1 Level is Associated with Poor Response to Steroid Therapy in Childhood-Onset Nephrotic Syndrome.

Nephrotic syndrome (NS) is one of the most common kidney diseases seen in children. It is a disorder characterized by severe proteinuria, hypoproteinemia, hyperlipidemia, and generalized edema resulting from alterations of permeability at the glomerular capillary wall. Endothelin-1 (ET1) has a central role in the pathogenesis of proteinuria and glomerulosclerosis and has a role in assessment of the clinical course of NS in children. This study aims to investigate the relationship between ET1 serum level and the response to steroid therapy in children with primary NS. Serum ET1 levels were evaluated in 55 children with NS. They were classified into two groups: 30 patients with steroid-sensitive NS (SSNS) and 25 patients with steroid-resistant NS (SRNS). The SSNS group was further divided into infrequent-relapsing NS (IFRNS) and steroid-dependent NS (SDNS), while the SRNS group was subdivided into two groups according to renal pathology. ET1 levels were significantly higher in the SRNS group (52.5 ± 45.8 pg/dL) compared to the SSNS group (18.3 ± 17 pg/dL) (P <0.001). Furthermore, ET1 levels were significantly higher in SDNS (54.3 ± 18.6) compared to IFRNS (11.9 ± 7.8, P = 0.001). There was no statistically significant difference in ET1 levels between minimal change disease group and focal segmental glomerulosclerosis group, (P = 0.28). Serum ET1 can be considered as a predictor for response to steroid therapy.

Progress in adolescent health and wellbeing: tracking 12 headline indicators for 195 countries and territories, 1990-2016.

BACKGROUND: Rapid demographic, epidemiological, and nutritional transitons have brought a pressing need to track progress in adolescent health. Here, we present country-level estimates of 12 headline indicators from the Lancet Commission on adolescent health and wellbeing, from 1990 to 2016. METHODS: Indicators included those of health outcomes (disability-adjusted life-years [DALYs] due to communicable, maternal, and nutritional diseases; injuries; and non-communicable diseases); health risks (tobacco smoking, binge drinking, overweight, and anaemia); and social determinants of health (adolescent fertility; completion of secondary education; not in education, employment, or training [NEET]; child marriage; and demand for contraception satisfied with modern methods). We drew data from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2016, International Labour Organisation, household surveys, and the Barro-Lee education dataset. FINDINGS: From 1990 to 2016, remarkable shifts in adolescent health occurred. A decrease in disease burden in many countries has been offset by population growth in countries with the poorest adolescent health profiles. Compared with 1990, an additional 250 million adolescents were living in multi-burden countries in 2016, where they face a heavy and complex burden of disease. The rapidity of nutritional transition is evident from the 324·1 million (18%) of 1·8 billion adolescents globally who were overweight or obese in 2016, an increase of 176·9 million compared with 1990, and the 430·7 million (24%) who had anaemia in 2016, an increase of 74·2 million compared with 1990. Child marriage remains common, with an estimated 66 million women aged 20-24 years married before age 18 years. Although gender-parity in secondary school completion exists globally, prevalence of NEET remains high for young women in multi-burden countries, suggesting few opportunities to enter the workforce in these settings. INTERPRETATION: Although disease burden has fallen in many settings, demographic shifts have heightened global inequalities. Global disease burden has changed little since 1990 and the prevalence of many adolescent health risks have increased. Health, education, and legal systems have not kept pace with shifting adolescent needs and demographic changes. Gender inequity remains a powerful driver of poor adolescent health in many countries.

Delusional ideation during the perinatal period in a community sample.

BACKGROUND: Despite the prevalence of mental health problems during the perinatal period, little research has examined psychotic symptoms in a community sample across pregnancy and the postpartum. Exposure to environmental risk factors, and immigration in particular, are associated with increased risk for psychotic disorders. The current investigation examined whether psychosocial risk and immigrant status would predict levels of delusional ideation across the perinatal period when controlling for depression, anxiety, and demographic factors. METHODS: A community sample of 316 pregnant women was assessed at 12-14 and 32-34weeks gestation during routine clinic visits, and at 7-9weeks postpartum during a home visit. Measures included self-report ratings of psychosocial risk (e.g., history of mental health problems or abuse, stressful life events, lack of social support), pregnancy-related anxiety, depressive symptomatology, and delusional ideation. RESULTS: There was less delusional ideation during the postpartum period than during early pregnancy. Across all time points, levels of delusional ideation were lower than in the general population. Analyses using multilevel modeling indicated significant fixed-effects for the variables time, age, partnership, being religious and prenatal anxiety, but not depressive symptomatology, on delusional ideation. Immigrant status moderated the effect of psychosocial risk such that greater psychosocial risk predicted more symptoms of delusional ideation among immigrants, but not non-immigrants. CONCLUSION: Psychosocial risk factors place immigrant women at an increased likelihood for experiencing delusional ideation during the perinatal period.
