RESUMEN

INTRODUCTION: Postgraduate medical trainees (PGs) in developing nations face various educational hurdles due to limited access to quality resources and training facilities. This study aimed to assess the effectiveness of e-learning, particularly Massive Open Online Courses (MOOCs), within postgraduate medical education. It involved the development of a customized online course focused on osteoporosis for PGs and an examination of their perspectives and preferences concerning online learning methods like Virtual Learning Environment (VLE) platforms. METHODS: The study was conducted from January 2018 to December 2020. A multi-institutional, multidisciplinary team was assembled to design an osteoporosis course on the VLE platform. PGs (n = 9) from diverse disciplines and institutions were selected with informed consent. Focus group discussions (FGDs) among these PGs identified their preferences for the online course, which subsequently guided the development of the MOOC. The modular MOOC comprised recorded micro-lectures, flashcards, videos, case challenges, and expert interviews. The educational impact of the VLE was assessed using pre- and post-module tests among the participants, and their perceptions of the PGs and course facilitators were gathered via an online survey. RESULTS: The study identified the involvement of PGs in the course design process as beneficial, as it allowed for content customization and boosted their motivation for peer-to-peer learning. During the FGDs, PGs expressed a strong preference for flexible learning formats, particularly short downloadable presentations, and micro-lectures. They also identified challenges related to technology, institutional support, and internet connectivity. In the subsequently customized MOOC course, 66% of PGs (n = 6) attempted the pre-test, achieving a mean score of 43.8%. Following the VLE module, all PGs (n = 9) successfully passed the end-of-module test, averaging a score of 96%, highlighting its impact on learning. The majority (n = 8, 88.9%) agreed that the course content could be applied in clinical practice, and 66.7% (n = 6) expressed extreme satisfaction with the learning objectives and content. Participants favoured end-of-module assessments and the use of best-choice questions for evaluation. CONCLUSION: This study highlights the importance of virtual learning, particularly MOOCs, in addressing the educational challenges faced by developing nations. It emphasizes the need for tailored online courses that cater to the preferences and requirements of PGs. The findings suggest that MOOCs can foster collaboration, networking, and opportunities for professional development, and interdisciplinary collaboration among faculty members can be a key strength in course development. This research provides valuable insights for educators, institutions, and e-learning developers seeking to enhance their teaching methodologies and establish accessible educational environments in the digital age.

RESUMEN

OBJECTIVE: To investigate the response of nutritional supplement (LNS-PLW) on appetite score, energy intake, insulin and glucose levels in preeclamptic women. DESIGN & PARTICIPANTS: Sixty under-weight preeclamptic primigravida were divided into two groups randomly and provided LNS-PLW/Placebo in the fasted state. Blood samples were collected at fasting state, after 30mins of supplementation, "ad libitum buffet" breakfast and lunch for glucose and insulin levels. RESULTS: Total energy intake was higher significantly in the LNS-PLW group, although during breakfast it was significantly reduced. The insulin and glucose concentration was significantly increased after 30min of supplementation in the LNS-PLW group. CONCLUSION: Intake of the LNS-PLW by pre-eclamptic women had short-term suppression on subsequent meal but improved total energy intake during trial.

RESUMEN

Background: Micronutrient deficiencies including vitamin A, vitamin D, and zinc are highly prevalent in children below 5 years of age in low and -middle-income countries. We aimed to evaluate the effectiveness of ready-to-use Lipid-based Nutrient Supplement-Medium Quantity (LNS-MQ) local name "Wawa-mum" on plasma micronutrient status, hemoglobin concentration and anthropometric measurements. Methods: A community-based non-randomized trial was conducted in the Kurram district of Khyber Pakhtunkhwa from January 2018 to June 2019. A total of 110 children aged 6 to 23 months old were recruited and allocated to the intervention and control arm of the study. A total of 57 children in the intervention arm received a daily ration of 50 g of Wawa-mum, for one year. To assess the impact of the intervention on primary outcome measures, i.e., serum vitamin A, D concentration, plasma zinc, and hemoglobin concentration. Blood samples were collected at baseline and after one year following the intervention. The vitamins concentration in serum were assessed using Enzyme-Linked Immunosorbent Assay (ELISA) and plasma zinc by atomic absorption spectrometry. The hemoglobin concentration was measured by an automated hematology analyzer. A 24-h dietary recall interview was used to assess the nutrient intake adequacy. Multivariate Linear regression models were used to analyze the outcomes while controlling for potential confounders. Results: In the intervention arm, children had on average 6.2 µg/dL (95% CI 3.0-9.3, value of p<0.001) increase in the serum vitamin A concentration, 8.1 ng/mL (95% CI 1.3-14.9, value of p 0.02) increase in serum vitamin D concentration and 49.0 µg/dL (95% CI 33.5-64.5, value of p<0.001) increase in the plasma zinc concentration, and 2.7 g/dL (95% CI 2.0-3.3, value of p<0.001) increase in hemoglobin concentration while adjusted for covariates. An addition, length-for-age z-score (LAZ), weight-for-length z-score (WLZ), weight-for-age z-score (WAZ), and prevalence of undernutrition including stunting, wasting, and underweight were calculated as a secondary outcome to investigate the impact of micronutrients on growth parameters, that has been improved significantly after receiving the Wawa-mum. Conclusion: Wawa-mum (LNS-MQ) is an effective intervention to improve the micronutrient status, hemoglobin concentration, and growth parameters in 6 to 23 months children, which can be scaled up in the existing health system to address the alarming rates of under nutrition in Pakistan and other developing countries.

RESUMEN

Gut microbiota composition has caused perplexity in developing precision therapy to cure metabolic disorders. However, recent research has focused on using daily diet and natural bioactive compounds to correct gut microbiota dysbiosis and regulate host metabolism. Complex interactions between the gut microbiota and dietary compounds disrupt or integrate the gut barrier and lipid metabolism. In this review, we investigate the role of diet and bioactive natural compounds in gut microbiota dysbiosis and also the modulation of lipid metabolism by their metabolites. Recent studies have revealed that diet, natural compounds and phytochemicals impact significantly on lipid metabolism in animals and humans. These findings suggest that dietary components or natural bioactive compounds have a significant impact on microbial dysbiosis linked to metabolic diseases. The interaction between dietary components or natural bioactive compounds and gut microbiota metabolites can regulate lipid metabolism. Additionally, natural products can shape the gut microbiota and improve barrier integrity by interacting with gut metabolites and their precursors, even in unfavourable conditions, potentially contributing to the alignment of host physiology.

RESUMEN

Background: Community engagement has shown to be fundamental component of the response to previous disease outbreaks. This study aimed co-design and implement a culturally appropriate COVID-19 risk communication and community engagement strategy with a resource-poor rural community in Northwest Pakistan. Methods: Participatory Action Research (PAR) was conducted from January 2021 to March 2022. Five PAR meetings took place with community members (n = 30) to: (1) explore how the COVID-19 pandemic impacted on the community; (2) identify challenges to limit the spread of the virus; (3) identify and implement solutions to these challenges; and (4) highlight the enablers, challenges and knowledge of the cultural context needed to optimize safety during emergencies. Focus group discussions (N = 6) with community members not involved in the PAR meetings (N = 50) and children of the community (N = 26) were conducted following the PAR meetings. Thematic analysis of the PAR and focus group data was conducted. Results: Delivery of messages on how to keep families safe, provision of personal protective equipment and improved water systems were part of the strategies taken by the community to create awareness and reduce the spread of COVID-19. Nine themes were identified: Attitudes to the pandemic: From skepticism to acceptance, Changing attitudes about vaccination: rumors and trust, COVID-19 and Faith, Social impact of the pandemic, Access to water, Resource mobilization: personal protective equipment, Spaces where collaborative effort can bring to solutions, Agents of change, and Empowerment of women. Discussion: The participatory approach of this research allowed understanding of the challenges faced by the community to engage in behavior change strategies to reduce the spread of COVID-19 and enabled the community to find sustainable solutions. Engagement with the community empowered men and women to be agents of change and promoted necessary precautionary actions to reduce the risk of infection within their community. Conclusion: Participatory approach highlighted the importance of engaging with and integrating to local culture and values to overcome challenges such as gender imbalance and distrust. Findings of this study are relevant to others working in diverse cultural settings in similar crises events regardless of particular cultural variations.

RESUMEN

Cost-effective interventions are needed to address undernutrition, particularly micronutrient deficiencies, which are common in children under the age of five in low- and middle-income countries. A community-based, non-randomized clinical trial was undertaken in the Kurram district of Khyber Pakhtunkhwa from January 2018 to June 2019, to evaluate the effect of locally produced micronutrient powder (local name: Vita-Mixe) on plasma micronutrient status, hemoglobin level, and anthropometric outcomes. Children aged 24-48 months old were recruited and allocated to the intervention and control arm of the study. The enrolled children in the intervention arm received one micronutrient powder (MNP) sachet for consumption on alternate days for 12 months. To assess the impact of the intervention on plasma levels of zinc, vitamin D, vitamin A, and hemoglobin level, blood samples were taken at baseline and after one year following the intervention. The analysis was conducted using Enzyme-Linked Immunosorbent Assay (ELISA), atomic absorption spectrometry, and an automated hematology analyzer. For the impact on growth parameters, the anthropometric assessment was performed using WHO standard guidelines. A 24 h dietary recall interview was used to assess the nutrient intake adequacy. Results showed that in the intervention arm, children had on average a 7.52 ng/mL (95% CI 5.11-9.92, p-value < 0.001) increase in the plasma level of vitamin A, 4.80 ng/mL (95% CI 1.63-7.95, p-value < 0.002) increase in vitamin D levels and 33.85 µg/dL (95% CI 24.40-43.30, p-value < 0.001) increase in the plasma zinc level, as well as a 2.0g/dL (95% CI 1.64-2.40, p-value < 0.001) increase in hemoglobin level. Statistically significant improvement was observed in the weight-for-height z-score (WHZ) (from -1.0 ± 0.88 to -0.40 ± 1.01, p < 0.001) and weight-for-age z-score (WAZ) (from -1.40 ± 0.50 to -1.05 ± 0.49, p < 0.001) in the intervention group compared to the control group. No statistically significant change was observed in the height-for-age z-score (HAZ) in the intervention group (p = 0.93). In conclusion, micronutrient powder supplementation is a cost-effective intervention to improve the micronutrient status, hemoglobin level, and growth parameters in under-five children, which can be scaled up in the existing health system to address the alarming rates of undernutrition in Pakistan and other developing countries.

RESUMEN

The 'flipped classroom (FCR)' is a teaching pedagogy where students are actively involved in the learning process. It reduces passivity, enables students to become active learners through reasoning and concept application and facilitates student interaction with their peers and instructors. This instructional approach enhances retention and decreases distraction by engaging students. OBJECTIVES: The purpose of this study was to train the faculty of the medical college and school of nursing in developing FCRs as an innovative teaching and learning strategy, to facilitate them in conducting flipped sessions for their students and to explore the experiences of medical, nursing students along with faculty members regarding the FCR they had attended and conducted. SETTING: Private medical college. PARTICIPANTS: A total of 442 students from medical college and school of nursing and midwifery participated in the evaluation survey with a female to male ratio of 339:103. Students who attended the flipped class sessions were included in the study sample. Students who did not complete the forms were excluded from the study. Nine faculty members who attended the workshop, agreed to facilitate the FCR session were invited to participate in the focus group discussion. RESULTS: Both medical and nursing students found FCR format stimulating. A significantly higher proportion of medical students (73%) found the FCR more engaging and interesting than a traditional lecture as compared with nursing students (59%) (p=0.009). Similarly, 73% of medical students believed the learning objectives of both the non-face-to-face and face-to-face sessions were shared with them as compared with the 62% of nursing students who believed the same (p=0.002). A significantly higher proportion of medical (76%) versus nursing (61%) students found the FCR format more useful for application of their theoretical knowledge into clinical practice (p=0.030). CONCLUSION: Students found the FCR more engaging and interesting in terms of applying theoretical knowledge into practice. Similarly, faculty found this strategy as effective but challenging in terms of involving and engaging students in the learning process. It is recommended to conduct more FCR sessions for an interactive and student-centred learning, but proper planning of the session and using variety of technological tools to engage learners is a key to success.

RESUMEN

Oral lipid-based nutritional supplements (LNS) are designed to ensure dietary adequacy and to improve malnourishment in children. Therefore, this study investigated the effects of 4 weeks of LNS on appetite, energy intake, and lipid profile of moderately underweight children (5-10 years old) with BMI-Z score between -2 and - 3 SDS, recruited in a single-blind randomized control trial. In addition to the regular dietary intake, fasting blood samples, anthropometric measurements, energy intake, and appetite responses were obtained before and after 4 weeks of LNS (535 kcal) or PLACEBO (92 kcal). After 4 weeks of supplementation mean energy intake (kcal) (p < .001), body weight (kg) (p < .001), BMI (kg/m2) (p < .01), mid-upper arm circumference (cm) (p < .01), total cholesterol (mg/dl) (p < .01) and fasting glucose (mg/dl) (p < .01) were raised significantly in the LNS group as compared to the PLACEBO group. No significant changes were detected in appetite responses (p > 0.05). In conclusion, LNS increases the overall energy intake, but does not affect the appetite but may induce hyperglycemia and hyperlipidemia.

RESUMEN

OBJECTIVE: To determine the impact of high-energy nutritional supplements on appetite, appetite regulators, energy intake and macronutrients level among underweight primigravidae. Methods: The single-blind randomised controlled trial was conducted from April 26, 2018, to August 10, 2019, in tertiary care hospitals of Khyber Pakhtunkhwa province of Pakistan, after approval from the ethics review committee of Khyber Medical University, Peshawar, and comprised underweight primigravidae who were randomly allocated to high energy nutritional supplement group A and placebo group B. Appetite questionnaires were filled and blood samples were obtained in fasting state, at 30, 60, 120, 210 and 270 minutes to measure blood glucose, insulin, peptide YY and cholecystokinin. Breakfast and lunch were served at 30 minutes and 210 minutes after supplementation, respectively. Data was analysed using SPSS 20. RESULTS: Of the 36 subjects, 19(52.8%) were in group A and 17(47.2%) were in group B. The overall mean age was 18.66 ± 2.5 years. Energy intake in group A was significantly higher than group B (p<0.001), and so were mean protein and fats (p<0.001). The subjective appetite perceptions for 'hunger' and 'desire to eat' were significantly lower (p<0.001) before lunch in group A. Plasma concentrations of appetite hormones corresponded to the appetite perceptions and were significantly higher in group A after breakfast and lunch for peptide YY, cholecystokinin and insulin compared to group B (p<0.001). CONCLUSIONS: High-energy nutritional supplement was found to have short-term suppressive effect on energy intake and appetite. Trial registration: ClinicalTrials.gov Identifier: ISRCTN 10088578.

RESUMEN

Background and Objectives: In pre-eclampsia, restricted blood supply due to the lack of trophoblastic cell invasion and spiral artery remodeling is responsible for adverse pregnancies and maternal outcomes, which is added to by maternal undernutrition. This study was designed to observe the effect of multiple nutritional micronutrient supplements on the pregnancy outcomes of underweight pre-eclamptic women. To investigate the effects of lipid-based multiple micr supplementations (LNS-PLW) on pregnancy and maternal outcomes in underweight primigravida pre-eclamptic women. Materials and Methods: A total of 60 pre-eclamptic, underweight primigravida women from the antenatal units of tertiary care hospitals in the Khyber Pakhtunkhwa Province, Pakistan, were randomly divided into two groups (Group 1 and Group 2). The participants of both groups were receiving routine treatment for pre-eclampsia: iron (60 mgs) and folic acid (400 ug) IFA daily. Group 2 was given an additional sachet of 75 gm LNS-PLW daily till delivery. The pregnancy outcomes of both groups were recorded. The clinical parameters, hemoglobin, platelet count, and proteinuria were measured at recruitment. Results: The percentage of live births in Group 2 was 93% compared to 92% in Group 1. There were more normal vaginal deliveries (NVDs) in Group 2 compared to Group 1 (Group 2, 78% NVD; group 1, 69% NVD). In Group 1, 4% of the participants developed eclampsia. The frequency of cesarean sections was 8/26 (31%) in Group 1 and 6/28 (22%) in Group 2. The number of intrauterine deaths (IUDs) was only 1/28 (4%) in Group 2, while it was 2/26 (8%) in Group 1. The gestational age at delivery significantly improved with LNS-PLW supplementation (Group 2, 38.64 ± 0.78 weeks; Group 1, 36.88 ± 1.55 weeks, p-value 0.006). The Apgar score (Group 2, 9.3; Group 1, 8.4) and the birth weight of the babies improved with maternal supplementation with LNS-PLW (Group 2, 38.64 ± 0.78 weeks: Group 1, 36.88 ± 1.55; p-value 0.003). There was no significant difference in systolic blood pressure, while diastolic blood pressure (Group 2, 89.57 ± 2.08 mmHg; Group 1, 92.17 ± 5.18 mmHg, p-value 0.025) showed significant improvement with LNS-PLW supplementation. The hemoglobin concentration increased with the LNS-PLW supplement consumed in Group 2 (Group 2, 12.15 ± 0.78 g/dL; Group 1, 11.39 ± 0.48 g/dL, p-value < 0.001). However, no significant difference among the platelet counts of the two groups was observed. Conclusions: The pregnancy and maternal outcomes of underweight pre-eclamptic women can be improved by the prenatal daily supplementation of LNS-PLW during pregnancy, along with IFA and regular antenatal care and follow-up.

RESUMEN

Background: Under-nutrition is a major public health problem worldwide. Several studies have documented the effects of vitamin D and calcium supplements in healthy children and in children with bone abnormalities but the effects of multiple micronutrients supplementation in underweight children is limited in literature. Methods: In this randomized controlled trial 38 participants were recruited and divided into two groups of 19 subjects. On the first day of experimental trial, in fasting state 5cc blood samples were collected from all subjects followed by their anthropometric measurements, and serum levels of calcium and vitamin D. All subjects of one group were given Lipid-based nutritional supplement (LNS) and whereas the other group was given the placebo. After one month of compliance the same measurements were repeated and compared. Results: After one month of supplementation mid-upper arm circumference (p=0.005), weight (p<0.001), height (p=0.000), and BMI-Z score (p=0.002) the energy intake (p<0.001), were significantly increased in LNS as compared to Placebo. However, no improvement was observed in the plasma vitamin D (p=0.44) and calcium levels (p=0.46) of underweight children in both groups. Conclusion: Multi micronutrient supplementations are effective in improving anthropometry in the short duration of time. They also improve the energy intake of underweight children. However, no improvement is observed in levels of vitamin D and calcium in LNS group even after a one-month use.

RESUMEN

BACKGROUND: Undernutrition including micronutrient deficiency results in adverse health-related outcomes in children of low-medium income countries. This study aims to explore the effect of four weeks of Lipid-based nutritional supplement (LNS) on energy intake, anthropometry and micronutrient status in moderate acute malnourished children. METHODS: Thirty-four children with mean age 7.08±1.47 years and a BMI Z score between -2 and -3 SDS were randomized into LNS and Placebo groups in a single blind randomized control trial. Energy intake, fasting blood samples, and anthropometric measurements were obtained prior to and after four weeks of LNS (535 kcal) or Placebo (92kcal) supplementation in addition to their habitual dietary intake. RESULTS: During four weeks of supplementation, energy intake (kcal) [(611±155) to (987±224), p<0.001)], weight (kg) [(17.5±2.83) to (18.1±3.24), p< 0.001], mid-upper arm circumference (cm) [(14.8±0.91) to (15.1±0.84), p=0.005)] and BMI (kg/m2) [(12.9±0.33) to (13.3±0.45), p=0.002] was significantly improved in the LNS group compared to Placebo. A significant increase in hemoglobin (g/ml) [(12.2±1.14) to (13.7±1.69), p<0.01] and iron levels (µg/dl) [(0.36±0.09) to (0.67±0.20), p<0.001] were observed in the LNS group. No significant differences were detected in the copper and zinc levels. CONCLUSIONS: Lipid-based nutritional supplement is effective in improving energy intake, nutritional outcomes and iron but not copper and zinc. The trial was registered at www.isrctn.com under reference: ISRCTN147181521.

RESUMEN

BACKGROUND: Adiponectin plays an important role in glucose metabolism and released in response to insulin. It helps to decrease glucose levels and insulin resistance; however, this relation is not been studied in pregnant ladies. Objective was to determine serum adiponectin level and glycaemic status in pregnant women belonging to Peshawar, Khyber Pakhtunkhwa (KPK) and to find any possible relationship between them. METHODS: Hundred pregnant women with gestational diabetes mellitus (GDM) and 100 healthy pregnant women without GDM were randomly selected in a cross-sectional study. After an overnight fast, their blood samples were taken for determination of serum adiponectin, glycosylated haemoglobin (HbA1c) and fasting blood glucose (FBG). The relationship of adiponectin with glycaemic status was determined with Pearson Correlations coefficient (r). RESULTS: Pregnant women with GDM when compared to healthy pregnant women showed significantly low levels of serum adiponectin (µg/mL) (2.2±0.2 vs. 11.25±4.8, p<0.05) and significantly high level of FBG (mg/dl) (182.7±64.2 vs. 93.6±5.9, p<0.05) and HbA1c (%) (7.4±0.1 vs. 5.4±0.1, p<0.05). Serum adiponectin level showed a statistically significant negative correlation with FBG (r = -0.203, p=0.042) and HbA1c (r = -0.744, p=0.000) in pregnant women with GDM. CONCLUSIONS: Serum adiponectin concentration is markedly decreased in pregnant women with GDM which concludes that Hypoadiponectinemia is related with deranged (elevated) glycaemic status in pregnancy. Moreover, adiponectin is associated negatively with FBG and HbA1c in the studied population.

RESUMEN

BACKGROUND: Eclampsia and preeclampsia are among the serious complications of gestation and threaten the lives of both mother and foetus. A protein called visfatin, one of these adipokines, is evaluated for its effects on serum electrolytes, lipid profile and hepatic enzymes in preeclamptic and eclamptic patients. METHODS: A sum of 234 pregnant women were enrolled in this crosssectional study and divided in to 2 main groups, i.e., Group A (eclamptic/preeclamptic) Group B (control) pregnant women respectively. Serum visfatin levels (ng/mL), serum electrolytes and liver enzymes were determined for every patient, using relative diagnostic kits. Anthropometric measurements were also noted. RESULTS: A total of 234 women (cases; n=160, controls; n=74) with gestation age of ≥20 weeks participated in this study. Group A had 86 (36.75%) women with preeclampsia and 74 (31.62%) women with eclampsia whereas Group B had 74 (31.62%) normotensive pregnant women. A strong significantly positive association was recorded for systolic (R2=78.78; p-value <0.000) and diastolic blood pressure (BP) (R2=78.52; p-value <0.000). Similar result was obtained for serum sodium ions (R2=3.09; p-value <0.002) and chloride ions (R2=7.36; p-value <0.000). Alkaline phosphatases (ALP) (R2=63.47; p-value <0.000) had also shown a strong positive and statistically significant association with visfatin levels. CONCLUSIONS: Serum visfatin significantly decreased the sodium and chloride levels whereas the levels of potassium remained unaffected. A very strong and positive association of visfatin levels with levels of bilirubin and alkaline phosphatases was also observed (ALP) but it found no effect on aspartate transferases (AST).

RESUMEN

BACKGROUND: Triglycerides are a type of storage fat present in serum of both normal and obese individuals. Triglycerides are normally present in human tears. The presence of qualitative fats in the tears affect the pupillary response to the external light stimulus which is measured through portable field dark adaptometer (PFDA) device. The current study was conducted to evaluate the levels of triglycerides in serum and tears of obese and non-obese humans and its relationship with pupillary response. METHODS: This descriptive cross-sectional study was conducted at Institute of Basic Medical Sciences, Khyber Medical University, Peshawar. A total of 500 participants were recruited out of which only 50 qualified for the study as per inclusion criteria. Out of these 50, 25 (50%) were obese and 25 (50%) were non-obese. Serum triglycerides were measured by using Micro lab 300 biochemistry analyzer, while thin layer chromatography was used to detect triglycerides in tear samples.. RESULTS: Triglycerides were detected only in tears of obese individuals. No statistically significant difference was observed in the serum levels of triglycerides between the two groups (p=0.849). CONCLUSIONS: The presence of triglycerides in tears of obese adults caused a low pupillary response as compared to normal individuals.

RESUMEN

Biofortification of wheat is potentially a sustainable strategy to improve zinc intake; however, evidence of its effectiveness is needed. A household-based, double-blind, cluster-randomized controlled trial (RCT) was conducted in rural Pakistan. The primary objective was to examine the effects of consuming zinc-biofortified wheat flour on the zinc status of adolescent girls aged 10−16 years (n = 517). Households received either zinc-biofortified flour or control flour for 25 weeks; blood samples and 24-h dietary recalls were collected for mineral status and zinc intake assessment. Plasma concentrations of zinc (PZC), selenium and copper were measured via inductively coupled plasma mass spectrometry and serum ferritin (SF), transferrin receptor, alpha 1-acid glycoprotein and C-reactive protein by immunoassay. Consumption of the zinc-biofortified flour resulted in a moderate increase in intakes of zinc (1.5 mg/day) and iron (1.2 mg/day). This had no significant effect on PZC (control 641.6 ± 95.3 µg/L vs. intervention 643.8 ± 106.2 µg/L; p = 0.455), however there was an overall reduction in the rate of storage iron deficiency (SF < 15 µg/L; control 11.8% vs. 1.0% intervention). Consumption of zinc-biofortified flour increased zinc intake (21%) but was not associated with an increase in PZC. Establishing a sensitive biomarker of zinc status is an ongoing priority.

RESUMEN

BACKGROUND AND OBJECTIVE: Maternal under nutrition and low birth weight babies are among the common tragedies of developing countries like Pakistan. Preeclampsia and its significant association with fetal growth restriction due to spiral arteries remodeling and trophoblastic invasion decreases nutritional supply to growing fetus added by maternal under nutrition. This study was designed to see the effects of lipid based nutritional supplements for pregnant and lactating women LNS-PLW on maternal and fetal outcome of pre-eclampsia. METHODS: Sixty underweight pre-eclamptic women were randomly assigned into two study Groups from April 2018 to December 2019 at the antenatal units of the tertiary Health care facilities of Lady Reading Hospital, Hayatabad Medical Complex Peshawar and Civil Hospital Matta Swat, KPK Pakistan in a randomized clinical trial. Participants were on routine drugs for pre-eclampsia and Iron and Folic Acid (60mg, 400 µg) daily, while participant of Group-2 (n=30) received one sachet of Lipid based nutritional supplement for pregnant and lactating women LNS-PLW in addition daily till delivery. The birth weight, gestational age, head-circumference, and birth length of babies were measured. RESULTS: The significant improvement found in the birth weight (p-value 0.003), gestational age (p-value 0.006), head circumference (P-value of 0.0006) and birth length (P-value of 0.0017) of babies of Group-2 women. We observed that addition of Lipid based nutritional supplement for pregnant and lactating women LNS-LPW improved the birth outcome in underweight women of pre-eclampsia. CONCLUSION: The Prenatal supplementation of Lipid based nutritional supplement for pregnant and lactating women LNS-PLW can improve birth weight, gestational age, length and head circumference of babies of underweight preeclamptic women.

RESUMEN

BACKGROUND/OBJECTIVE: Morning consumption of a single dose of high-energy oral nutritional supplement (ONS) in females with a lower BMI displaces some of the food eaten at breakfast but increases overall daily energy intake. This study investigated the effectiveness of ONS intake in the late afternoon and for longer duration. SUBJECTS/METHODS: Twenty-one healthy females (mean ± SD, age 25 ± 5 years; BMI 18.7 ± 1.2 kg/m2) participated in a randomised, crossover study with two experimental trials. In the afternoon of days 1-5, participants consumed either ONS (2.510 MJ) or low-energy PLACEBO drink (0.377 MJ) and recorded food eaten at home. On day six, energy intake was measured during buffet meals, and energy expenditure, appetite measurements and blood samples were collected throughout the day. RESULT: Over the 5-day period, in the ONS trial energy intake from evening meals was lower (ONS, 2.7 ± 0.25 MJ; Placebo, 3.6 ± 0.25 MJ, P = 0.01) but averaged total daily energy intake was higher (ONS, 9.2 ± 0.3 MJ; PLACEBO, 8.2 ± 0.4 MJ, P = 0.03). On day six, energy intake, appetite scores, plasma GLP-1 and PYY, and energy expenditure were not significantly different between the two trials but fasting insulin concentration and HOMAIR, were higher (P < 0.05) and insulin sensitivity score based on fasting insulin and TAG lower (P < 0.05) in ONS trial. CONCLUSION: Late afternoon consumption of ONS for five consecutive days by females with a lower BMI has only a partial and short-lived energy intake suppression and thus increases daily energy intake but reduces insulin sensitivity.

RESUMEN

Coastal wetlands primarily serve as natural sinks of trace metals and their importance for phytoremediation is well known at global level. There are some reports on trace metal availability in soil sediments of the Karachi coast but studies on accumulation and translocation to harvestable (Shoot) parts among halophytes of the littoral zones have not been conducted. Hence, phytoremediation potential of six naturally existing halophytes (Aeluropus lagopoides, Arthrocnemum macrostachyum, Atriplex stocksii, Avicennia marina, Cressa cretica and Suaeda fruticosa) was assessed for cleaning metal (Mn, Zn, Pb and Cr) polluted soils of the Karachi coast. Seasonal (winters, pre and post-monsoon summers) and spatial (three littoral zones: viz., site - I: Sandspit, site - II: Do-Dariya/Clifton and site - III: Korangi creek) variations in soil and plant metals of the Karachi coast were studied. Soil Zn, Pb and Cr were generally higher in winters, Mn and organic matter in summers (7-11%) while pH values ranged between 7.15 and 7.5 in all seasons at site - III. All tested species had potential for cleaning Pb through their harvestable part (shoots) with A. stocksii as prominent candidate (16 mg kg-1) at site - I. Cressa cretica emerged as exclusive candidate for Zn phytoremediation (96 mg kg-1) at site - I, while S. fruticosa, A. macrostachyum and A. lagopoides showed bioaccumulation in pre-monsoon summers at site II. Aeluropus lagopoides with higher Mn in post monsoon summers (62 at site - III and 53 mg kg-1 at site - II) and Cr (7.1 mg kg-1 at site - II and 14 mg kg-1 at site - III) appeared exclusive bioindicator with potential of for cleaning all metals (Mn, Zn, Pb and Cr) at different sites. Metal bioaccumulation at study sites appeared species specific and varied seasonally among tested halophytes.
