    Background. To assess fasting C-peptide and insulinindices using homeostatic model assessment (HOMA)in gestational diabetes mellitus (GDM).Methods. Gestational diabetes mellitus (n = 64, age:27.02 ± 0.53 years, BMI: 26.3 ± 0.5 kg/m2; mean ±SEM) and normal glucose tolerance NGT (n = 56, age:26.11 ± 0.55 years, BMI: 24.4 ± 0.4 kg/m2; mean ±SEM) screened according to WHO 2013 criteria. Glucosewas measured by oxidase method whereas fastinginsulin and C-peptide by ELISA. HOMA-IR, HOMA-B andHOMA-%S were calculated. Results. C-peptide was found higher in GDM comparedto NGT without any significant difference (P = 0.465).Fasting insulin (P = 0.063) and HOMA-IR (P < 0.001)were significantly higher while HOMA-B (P = 0.015)and HOMA-%S (P = 0.012) were significantly lower inGDM than those of NGT. BMI, bad obstetric history,multiparity and blood glucose were higher (P ≤ 0.05)in GDM while age, duration of gestation, family historyof DM did not differ (P = NS). C-peptide (0.185 ± 0.06vs 0.331 ± 0.44; P < 0.05), fasting insulin (4.88 ± 0.74vs 10.37 ± 0.74; P < 0.01) and HOMA-IR (1.04 ± 0.14 vs2.48 ± 0.18; P < 0.011) as well as HOMA-B were foundlower in GDM having BMI < 23 kg/m2 than those ofGDM with BMI ≥ 23. Conversely, HOMA-%S (115.52 ±14.63 vs 50.62 ± 3.39; P < 0.011) was higher in thesubgroup with BMI < 23 than the rest. Fasting bloodglucose (FBG) (P < 0.01) and fasting insulin (P < 0.05)were independent predictors for GDM. Conclusions. Fasting C-peptide did not differ betweenGDM and NGT. BMI was positively related with resistanceand secretion of insulin but inversely with sensitivity.HOMA model analyses revealed decreased insulinsensitivity and secretory capacity in GDM than NGT

    WSTĘP: Badania przeprowadzono w celu oceny stężenia peptydu C i wskaźników insulinowych w modelu homeostazy (HOMA) u kobiet z cukrzycą ciążową (GDM). METODY: Kobiety z cukrzycą ciążową (n = 64, wiek: 27,02 ± 0,53 roku, BMI: 26,3 ± 0,5 kg/m2; średnia ± SEM) i prawidłową tolerancją glukozy (NGT) (n = 56, wiek: 26,11 ± 0,55 roku, BMI: 24,4 ± 0,4 kg/m2; średnia ± SEM) zdiagnozowanymi zgodnie z kryteriami Światowej Organizacji Zdrowia 2013. Stężenie glukozy mierzono metodą oksydazową, natomiast stężenie insuliny na czczo i peptydu C metodą ELISA. Obliczono wskaźniki HOMA-IR, HOMA-B i HOMA-%S. WYNIKI: Stwierdzono, że stężenie peptydu C było wyższe u kobiet z GDM w porównaniu z kobietami z NGT, jednak różnica nie była istotna statystycznie (p = 0,465). Stężenie insuliny na czczo (p = 0,063) i wskaźnik HOMA-IR (p < 0,001) były istotnie wyższe, podczas gdy wskaźniki HOMA-B (p = 0,015) i HOMA- -%S (p = 0,012) były istotnie niższe w grupie z GDM niż u osób z NGT. Wskaźnik BMI i stężenie glukozy we krwi były wyższe, a obciążony wywiad położniczy i wielorództwo występowały częściej (p ≤ 0,05) w grupie GDM, natomiast wiek, czas trwania ciąży, dodatni wywiad rodzinny w kierunku cukrzycy nie różniły się między grupami (p = NS). Stężenie peptydu C (0,185 ± 0,06 v. 0,331 ± 0,44; p < 0,05), insulinemia na czczo (4,88 ± 0,74 v. 10,37 ± 0,74; p < 0,01) oraz wskaźniki HOMA-IR (1,04 ± 0,14 v. 2,48 ± 0,18; p < 0,011) oraz HOMA-B były niższe u kobiet z GDM, których wskaźnik BMI wynosił < 23 kg/m2 niż u osób z GDM z wyższymi wartościami wskaźnika BMI (≥ 23), natomiast wskaźnik HOMA-%S (115,52 ± 14,63 v. 50,62 ± 3,39; p < 0,011) był wyższy w podgrupie z BMI < 23. Stężenie glukozy we krwi na czczo (fasting blood glucose, FBG) (p < 0,01) i stężenie insuliny na czczo (p < 0,05) były niezależnymi predyktorami GDM. WNIOSKI: Stężenia peptydu C na czczo nie różniły się między grupami GDM i NGT. Wskaźnik BMI był dodatnio związany z insulinoopornością i wydzielaniem insuliny, ale odwrotnie związany z wrażliwością na insulinę. Analiza modelu HOMA wykazała zmniejszoną wrażliwość na insulinę i czynność wydzielniczą w GDM w porównaniu z NGT

    The aim of this review is to evaluate the effects of omega-3 long chain polyunsaturated fatty acids (n-3 LCPUFA) supplementation in pregnant and lactating women and infants during postnatal life, on the visual acuity, psychomotor development, mental performance and growth of infants and children. Eighteen publications (11 sets of randomized control clinical trial [RCTs]) assessed the effects of the n-3 LCPUFA supplementation during pregnancy on neurodevelopment and growth, in the same subjects at different time points; 4 publications (2 data sets from RCTs) addressed physiological responses to n-3 LCPUFA supplementation during pregnancy & lactation and 5 publications (3 data sets from RCTs) exclusively during lactation. Some of these studies showed beneficial effects of docosahexaenoic acid (DHA) supplementation during pregnancy and/or lactation especially on visual acuity outcomes and some on long-term neurodevelopment; a few, showed positive effects on growth. There were also 15 RCTs involving term infants who received infant formula supplemented with DHA, which met our selection criteria. Many of these studies claimed a beneficial effect of such supplementation on visual, neural, or developmental outcomes and no effects on growth. Although new well designed and conducted studies are being published, evidence from RCTs does not demonstrate still a clear and consistent benefit of n-3 LCPUFA supplementation during pregnancy and/or lactation on term infants growth, neurodevelopment and visual acuity. These results should be interpreted with caution due to methodological limitations of the included studies

    ObjectiveGestational diabetes mellitus (GDM) is a growing public health concern that has not been extensively studied. Numerous studies have indicated that a variant (rs8050136) of the fat mass-associated gene, FTO, is associated with both GDM and Type 2 diabetes mellitus(T2DM). We conducted a meta-analysis on the association between the FTO single nucleotide polymorphism (SNP) rs8050136 and T2DM, followed by a case-control study on the association of the said SNP and GDM in a sample of Bangladeshi women.MethodA total of 25 studies were selected after exploring various databases and search engines, which were assessed using the Newcastle-Ottawa Scale (NOS). The MetaGenyo web tool was used to conduct this meta-analysis. A case-control study was performed on 218 GDM patients and 284 controls to observe any association between FTO rs8050136 and GDM. Genotyping was performed using the tetra-primer amplification refractory mutation system-polymerase chain reaction (T-ARMS) method, and statistical analyses were performed using various statistical softwares.ResultsIn the meta-analysis 26231 cases and 43839 controls were examined. Pooled association analyses revealed a statistically significant relationship between the FTO rs8050136 polymorphism and an elevated risk of T2DM under all genetic models (PConclusionOur meta-analysis revealed a significant association between SNP rs8050136 of FTO with T2DM, and this variant was substantially associated with an increased risk of GDM in a sample of Bangladeshi multigravida women

    Community Health Workers (CHWs) can effectively implement maternal and child health interventions, but there is paucity of evidence on how to integrate child stimulation into these interventions, and their delivery at scale. In rural Bangladesh, CHWs implemented an intervention integrating psychosocial stimulation, nutrition, maternal mental health, water, sanitation, hygiene (WASH) and lead exposure prevention. In each of 16 intervention villages, one CHW worked with 20 households. CHWs bi-weekly held group meetings or alternated group meetings and home visits with pregnant women and lactating mothers. We assessed the intervention through five focus groups, four interviews and one group discussion with CHWs and their supervisors to explore success factors of implementation. CHWs' training, one-on-one supervision and introduction by staff to their own community, and adoption of tablet computers as job aids, enabled successful session delivery to convey behavioral recommendations. CHWs reported difficulties delivering session due to the complexity of behavioral recommendations and struggled with age-specific intervention material. Young children's attendance in group sessions generated distractions that undermined content delivery. We identified ways to minimize the difficulties to strengthen intervention-delivery during implementation, and scale-up. Iterative revisions of similarly integrated interventions based on qualitative evaluation findings could be delivered feasibly by CHWs and allow for implementation at scale
