Predicting the sagittal skeletal pattern using dental cast and facial profile photographs in children aged 9 to 14 years.

OBJECTIVE: To quantify prediction of sagittal skeletal pattern using anteroposterior dental relationships on dental casts and facial profile photograph. Methods: The cross-sectional study was conducted at the Aga Khan University Hospital, Karachi, from December 2016 to July 2017, and comprised orthodontic patients of either gender aged 9-14 years who attended the outpatient dental clinic. The sagittal skeletal relationship assessed on cephalometric radiographs was compared with anteroposterior dental and facial measurements on their dental cast and facial profile photographs. A prediction model was developed using multiple linear regression. The applicability of the prediction model was checked on an independent sample. Data was analysed using STATA 12. RESULTS: Of the 76 patients, about two-third (n=47) were females. The overall median age was 12.3 years (inter-quartile range: 1.8), with majority (60.5%) aged 12-14 years. The proportion of Class I, II and III malocclusion was 25 (32.9%), 50 (65.8%) and 1 (1.3%) respectively. Highest percentage of variability 47.4% in ANB angle was determined by the soft tissue ANB angle. 54.9% of the variability in the ANB angle could be explained by overjet, soft tissue ANB' angle, lower lip to E-line distance, Class II incisor relationship, history of malocclusion and thumb sucking, interaction terms between Class II incisor relationship and history of malocclusion, and history of thumb sucking and soft tissue ANB' angle. CONCLUSIONS: Sagittal skeletal relationship in an individual can be predicted with moderate accuracy using the prediction equation incorporating dental and facial variables along with history of malocclusion and thumb-sucking without potentially harmful exposure to cephalometric radiographs.

Macronutrient and fibre intake of young Spanish children with reference to their in utero growth status: Are they eating a healthy diet?

AIM: To compare macronutrient and fibre intake by pre-school children born with intra-uterine growth restriction (IUGR) or as appropriate for gestational age (AGA) and to compare their intake with paediatric nutritional recommendations for identification of potential areas of modification during early life. METHODS: A parental 3-day dietary record was obtained for children of age 1-6 years, born at Hospital Clinic, Barcelona, Spain (2002-2007) with IUGR (n = 37) or AGA (n = 53). Mean nutrient intake (adjusted for body mass index), nutrient adequacy ratios (NAR) and percentage of energy intake (EI%) were compared. RESULTS: Macronutrient and fibre intake of the two groups did not differ significantly. However, IUGR children showed significantly higher than the recommended levels of protein EI% (18 (95% confidence interval (CI) 16-19)), NAR for saturated fatty acids (SFAs) (1.2 (95% CI 1.1-1.5)) and NAR for carbohydrate (1.4 (95% CI 1.2-1.6)) and significantly lower than the recommended levels of NAR for unsaturated fatty acids (UFAs) (0.6 (95% CI 0.5-0.8)) and for fibre (0.6 (95% CI 0.5-0.8)). Likewise, children born with AGA showed similar pattern compared to the recommended levels for protein EI% (17 (95% CI 16-18)), NAR for SFAs (1.3 (95% CI 1.2-1.4)), NAR for UFAs (0.6 (95% CI 0.5-0.7)) and NAR for fibre (0.8 (95% CI 0.7-0.9)). CONCLUSION: Spanish pre-school children consume proteins and SFAs in abundance and UFAs and fibre in moderation. Reinforcement of healthy eating is recommended for long-term health benefits, especially for at-risk children born with IUGR, whose consumption of carbohydrate is additionally greater than that recommended.

Epidemiology and outcomes of out-of-hospital cardiac arrest in a developing country-a multicenter cohort study.

BACKGROUND: Out-of-hospital cardiac arrest (OHCA) is one of the leading causes of death and disability worldwide. Overall survival after an OHCA has been reported to be poor and limited studies have been conducted in developing countries. We aimed to investigate the rates of survival from OHCA and explore components of the chain of survival in a developing country. METHODS: We conducted a multicenter prospective cohort study in the emergency departments (ED) of five major public and private sector hospitals of Karachi, Pakistan from January 2013 to April 2013. Twenty-four hour data collection was performed by trained data collectors, using a structured questionnaire. All patients ≥18 years of age, presenting with OHCA of cardiac origin, were included. Patients with do-not-resuscitate status or referred from other hospitals were excluded. Our primary outcome was survival of OHCA patients at the end of ED stay. RESULTS: During the three month period, data was obtained from 310 OHCA patients. The overall survival to ED discharge was 1.6 % which decreased to 0 % at 2-months after discharge. More than half (58.3 %) of these OHCA patients were brought to the hospital in a non-EMS (emergency medical service) vehicle i.e. public or private transportation. Patients utilizing non-EMS transportation reached the hospital earlier with a median time of 23 min compared to patients utilizing any type of ambulances which had a delay of 7 min hospital reaching time (median time 30 min). However, patients utilizing ambulances with life-support facilities, as compared to all other types of pre-hospital transportation, had the shortest time to first life-support intervention (15 min). Most of the patients (92.9 %) had a witnessed cardiac arrest out of which only a small percentage (2.3 %) received bystander CPR (cardio pulmonary resuscitation). Median time from arrest to receiving first CPR was 20 min. Only 1 % of patients were found to have a shockable rhythm on first assessment. CONCLUSION: This study showed that the overall survival of OHCA is null in this population. Lack of bystander CPR and weaker emergency medical services (EMS) leading to a delay in receiving life-support interventions were some of the important observations. Poor survival emphasizes the need to standardize EMS systems, initiate public awareness programs and strengthen links in the chain of survival.

Are pre-school girls more likely to be under-nourished in rural Thatta, Pakistan?-a cross-sectional study.

BACKGROUND: Pakistan ranks third lowest on a global gender index (2013) and 13(th) highest on the prevalence of underweight among under-five children (2010). Through this population-based study, we examined gender differentials in the prevalence of stunting, wasting and under-weight defined by World Health Organization (WHO) Growth Standard among rural pre-school Pakistani children. METHODS: We performed secondary analysis of data collected through a cross-sectional survey of Thatta district during 1992-93. Prevalence ratios were calculated for 1051 children aged 0-35 months from 95 randomly selected villages of rural Pakistan using a clustered adjusted log binomial model. Level 1 variables included child and household characteristics and level 2 included village characteristics. RESULTS: Based on the new WHO growth reference, a major proportion of children were stunted (52.9 %), wasted (22.9 %) and under-weight (46.5 %). In a two-level model, compared to boys, girls had significantly greater risk of stunting [Prevalence Ratio (PR) (95 % C.I.) = 1.18 (1.03, 1.36)] and under-weight [P.R. (95 % C.I.) 1.14 (1.03, 1.26)], after adjustment of maternal literacy and village variables. Risk of wasting did not differ with gender [P.R. (95 % C.I.) = 1.04 (0.99, 1.15)]. Mothers of stunted and underweight children were respectively, 21 and 20 % more likely to be illiterate than those of normally nourished children. Sick children were at 16 % greater risk of wasting than those not reported ill. CONCLUSION: Greater prevalence of stunting and under-weight among girls suggests adoption of a gender sensitive approach in nutritional intervention programmes. Prompt management of childhood illnesses may reduce prevalence of wasting. Better literacy among rural mothers may reduce prevalence of stunting and under-weight. Whether gender differences in nutrition status are an underlying pathway for excessive girl mortality in rural Thatta needs further examination.

Unveiling school community perceptions of nutrition-friendly school initiatives in preschool settings in rural Sindh province, Pakistan: an exploratory study.

Introduction: In 1995, the World Health Organization launched its Global School Health Initiative to expand the Health Promoting School (HPS). The objective of this study was to explore the perception of the school community in implementing nutrition-friendly school initiatives in preschool settings. Methods: This paper delineates the exploratory phase of a mixed-method study, which broadly aims to assess the adoption of the Nutrition Friendly School Initiative (NFSI) through a preschool preparedness intervention package in rural Sindh province, Pakistan. The study sites include three campuses of the Aga Khan School (Mirpur Sakro, Junior Campus Vur, and a community-based school in Sujawal). Participants were selected purposively from these campuses and constituted a committee named 'school community,' which was responsible for implementing all activities outlined in the intervention package. Data was gathered through in-depth interviews and consultative meeting with the school community. Thematic analysis was employed for data analysis. Results: The analysis established five major themes that represent the participants' perception of school-based nutrition interventions in preschool settings. These five themes include (i) Challenges in health and nutrition for pre-school age children, (ii) Clarity in roles and responsibilities for school-based nutrition intervention, (iii) Advancing school-based nutrition activities and interventions, (iv) Recognizing resources requirements, (v) Opportunities and challenges for the way forward in school-based nutrition. Findings also suggest sustainability and scalability measures that include the aligning School Nutrition Policy with the school handbook, ways to engage with parents, a nutrition theme corner, the inclusion of a parenting component in the nutrition manual, and capacity building of the school community. Conclusion: Qualitative findings have guided the refinement of the intervention package, proposing additional measures for sustainability and scalability across AKES, P. The school community is hopeful that the implementation of the refined intervention package will enhance preschool preparedness toward achieving nutrition-friendly school checklist items. This study holds strong potential for replication in a public school setting and presents an opportunity to launch a school accreditation program to certify schools as Nutrition-friendly.

Influence of intrauterine growth status on aortic intima-media thickness and aortic diameter in near-term fetuses: a comparative cross-sectional study.

Intrauterine undernutrition may lead to fetal vascular programming. We compared abdominal aortic intima-media thickness (aIMT) and aortic diameter (aD) between appropriate for gestational age (AGA) and growth-restricted fetuses (GRF). We recruited 136 singleton fetuses at 34-37 weeks of gestation from Fetal Medicine Unit of Aga Khan University Hospital, Karachi (January-November 2017). Subjects were classified as AGA (n = 102) and GRF (n = 34) using INTER-GROWTH 21st growth reference and standard ultrasound protocol. Their far- and near-wall aIMT and aD were compared after adjustment of maternal age, first-trimester body mass index, fetal gender, hypertension and hyperglycemia in pregnancy. As the severity of growth restriction increased in GRF, aIMT and aD showed an increasing and a decreasing trend, respectively. Both far- and near-wall aIMT in GRF [(adj. ß = 0.082, 95% confidence interval [CI] 0.042-0.123) and (adj. ß = 0.049, 95% CI 0.010-0.089)] were significantly greater with reference to AGA fetuses. GRF subgroup analysis into small for gestational age (SGA) fetuses and intrauterine growth restricted (IUGR) revealed highly significant difference between AGA and IUGR for far (0.142 mm, P-value < 0.001) and near-wall aIMT (0.115 mm, P-value < 0.001) and marginally significant aD difference (0.51 mm, P-value 0.05). These findings suggest that the extent of fetal aortic remodelling is influenced by the severity of growth restriction. Hence, the targeted interventions for the cardiovascular health promotion of IUGR and SGA born neonates are desirable during early childhood, particularly in set ups with high prevalence of low birth weight babies.

The Efficacy of a Personalized mHealth Coaching Program During Pregnancy on Maternal Diet, Supplement Use, and Physical Activity: Protocol for a Parallel-Group Randomized Controlled Trial.

BACKGROUND: Adequate intake of macro- and micronutrients and adoption of an active lifestyle during pregnancy are essential for optimum maternal and fetal health and offspring development. Dietary counseling and advice regarding adequate physical activity are integral components of antenatal care. Personalized coaching through the use of mobile health (mHealth) that supports behavior modification is an innovative approach that needs exploration. OBJECTIVE: Our primary aim is to assess the efficacy of an mHealth program in improving diet, supplement use, and physical activity during pregnancy. Secondary objectives include evaluation of the program's effect on maternal and offspring health outcomes and assessment of its compliance and usability. METHODS: A randomized controlled trial was initiated at the Aga Khan University Hospital in Karachi, Pakistan, in January 2020. We aim to recruit 300 pregnant women in their first trimester who have smartphones, do not have comorbidities, and are not taking medications. The intervention group will be trained to use an mHealth app called PurUmeed Aaghaz. Through this app, the subjects will report information about their diet, supplement use, and physical activity and will receive personalized advice and three push messages as weekly reminders. The research assistant will obtain similar information from the control group via a paperless questionnaire; this group will receive standard face-to-face counseling regarding diet, supplement use, and physical activity. Data will be collected at enrollment and during four follow-up sessions scheduled 6 weeks apart. Primary study outcomes include improvements in diet (ie, change in mean dietary risk score from baseline to each follow-up), supplement use (ie, changes in mean supplement use score and biochemical levels of folic acid, iron, calcium, and vitamin D on a study subset), and mean duration of reported physical activity (minutes). Secondary study outcomes relate to maternal health (ie, gestational diabetes mellitus, gestational hypertension, pre-eclampsia, and gestational weight gain), newborn health (ie, birth weight and length and gestational age at delivery), and infant health (ie, BMI and blood pressure at 1 year of age). Compliance will be determined by the proportion of participants who complete the 6-month coaching program. Usability will be assessed based on features related to design, interface, content, coaching, perception, and personal benefit. RESULTS: The study was approved by the Ethics Review Committee of the Aga Khan University in 2017. The recruitment of study participants was completed in September 2021. All follow-ups and outcome assessments are expected to be completed by March 2023 and analysis is expected to be completed by June 2023. We expect the results to be published by the end of 2023. CONCLUSIONS: This study will be an important step toward evaluating the role of mHealth in improving behaviors related to a healthy diet, supplement use, and promotion of physical activity during pregnancy, as well as in influencing maternal and offspring outcomes. If proven effective, mHealth interventions can be scaled up and included in antenatal care packages at tertiary care hospitals of low- and middle-income countries.

Using mobile phones to improve young people's sexual and reproductive health in low- and middle-income countries: a systematic review protocol to identify barriers, facilitators and reported interventions.

BACKGROUND: Due to a growing reliance on mobile phone technology and decreasing mobile phone costs, the use of mobile phones is on the rise, especially among the youth population. Young people are responsive and enthusiastic to use novel approaches such as mHealth to access sexual and reproductive health information and services. Globally, reproductive health programs have used mHealth to provide sexual and reproductive health education and services to young people, through diverse communication channels. However, few attempts have been made to systematically review the mHealth programs for young people sexual and reproductive health (SRH) in low- and middle-income countries (LMICs). In addition, very little is known regarding the potential barriers and facilitators to the uptake of mobile phone interventions for improving young people SRH. This review aims to highlight facilitators and inhibitors to implementing and increasing uptake of mHealth interventions for young people's SRH, in LMICs specifically. Additionally, the review will identify the range of mHealth solutions which can be used for improving young people's SRH in LMICs. METHODS: The review will focus on comparing the various types of mHealth interventions/strategies that are used to improve young people's SRH services in LMICs. PubMed, CINAHL Plus, Science Direct, Cochrane, and gray literature will be explored using a detailed search strategy. The studies involving young people (adolescents and youth) aged 10-24 years to which mHealth interventions were delivered for improving their SRH outcomes will be included in this review. LMICs will be selected according to the World Bank's (WB) 2018 Country Classification list. Studies published between January 2005 and March 2018 will be included as the field of mHealth has emerged over the last decade. English language articles will be included as the authors are proficient in this language. DISCUSSION: The systematic review will assist researchers and SRH professionals in understanding facilitators and barriers to implementing and increasing the uptake of mHealth interventions for SRH in LMICs. Finally, this review will provide more detailed information about embracing the use of mobile phones at different levels of the healthcare system for improving young people's SRH outcomes.

Predicting the bracket bond failure rate in orthodontic patients: A retrospective cohort study.

The aim of this study was to determine the risk factors associated with orthodontic bracket bond failure and to develop a prediction equation for orthodontic bracket bond failure rate using the risk factors. This was a retrospective cohort study conducted on a sample of 690 brackets in orthodontic patients aged 10 to 28 years old (mean age 17.97±5.11 years old) visiting a dental hospital. The effect of various parameters of orthodontic bond strength was assessed on bracket failure rate using survival analysis. Parametric (exponential) regression analysis was used to determine the risk factors associated with bracket failure and a prediction equation was formulated to predict the bracket failure rate. The overall mean survival time for the brackets was 3.04 (2.9-3.17) years. The univariate analysis showed a statistically significant (P<0.05) association of bracket material, site, overjet, overbite, incisor and molar classification and age. The multivariate analysis showed a significant interaction between site and side along with bracket material, jaw, overjet and overbite in the model. The risk of bracket failure on the right posterior region is 7.7 times that in the right anterior region when adjusted for all other variables in the model (HR: 7.7; 95% CI: 4.3-13.6). The model including bracket material, jaw, overjet, overbite and interaction between site and side can be used as a predictor of hazard rate for orthodontic bracket failure. Care should be taken in bonding brackets in the posterior region, as their debonding rate is higher as compared to anterior region.

Does primary closure increase surgical site infection after intestinal stoma reversal? A retrospective cohort study.

BACKGROUND: This study was undertaken to test the veracity of the hypothesis that primary incision closure after intestinal stoma reversal in adult patients is associated with a greater risk of surgical site infection (SSI) than are open incisions. METHODS: A retrospective cohort study was conducted at the Surgical Department of the Aga Khan University Hospital, Karachi, Pakistan. The study included adult patients who underwent elective loop and double-barreled intestinal stoma (ileostomy or colostomy) reversal through peristomal incisions between January 2005 and May 2011. Files were reviewed independently by two surgeons to establish main exposure (closed or open surgical sites) and outcome; i.e., SSI based on U.S. Centers for Disease Control and Prevention criteria. RESULTS: Sample size calculation prior to the study required 71 patients to be included in each exposure arm. Patients with closed surgical sites were relatively younger (mean 36±15 [standard deviation] years) than those with open surgical sites (41±15 years), with a male preponderance in both groups. Fifteen patients were found to have SSI: 3/71 (4.2%) in open and 12/71 (16.9%) in closed incisions. The risk of SSI in closed surgical sites was 5.8 times greater than in open sites (95% confidence interval for relative risk 1.5-22.5) after adjusting for gender, body mass index (BMI), site of stoma, malignant disease, and preoperative chemo-radiotherapy. CONCLUSION: The risk of SSI in closed incisions is greater than that in open incisions. It is suggested that incisions not be closed primarily in patients undergoing stoma reversal.

Comparison of estimates of under-nutrition for pre-school rural Pakistani children based on the WHO standard and the National Center for Health Statistics (NCHS) reference.

OBJECTIVE: To compare estimates of under-nutrition among pre-school Pakistani children using the WHO growth standard and the National Center for Health Statistics (NCHS) reference. DESIGN: Prevalence of stunting, wasting and underweight as defined by WHO and NCHS standards are calculated and compared. SETTING: The data are from two cross-sectional surveys conducted in the early 1990s, the time frame for setting the baseline for the Millennium Development Goals: (i) National Health Survey of Pakistan (NHSP) assessed the health status of a nationally representative sample and (ii) Thatta Health System Research Project (THSRP) was a survey in Thatta, a rural district of Sindh Province. SUBJECTS: In all, 1533 and 1051 children aged 0-35 months from national and Thatta surveys, respectively. RESULTS: WHO standard gave a significantly higher prevalence of stunting for both national [36.7 (95 % CI 33.2, 40.2)] and Thatta surveys [52.9 (95 % CI 48.9, 56.9)] compared to the NCHS reference [national: 29.1 (95 % CI 25.9, 32.2) and Thatta: 44.8 (95 % CI 41.1, 48.5), respectively]. It also gave significantly higher prevalence of wasting for the Thatta survey [22.9 (95 % CI 20.3, 25.5)] compared to the NCHS reference [15.7 (95 % CI 13.5, 17.8)]. Differences due to choice of standard were pronounced during infancy and for severely wasted and severely stunted children. CONCLUSIONS: Pakistan should switch to the robustly constructed and up-to-date WHO growth standard for assessing under-nutrition. New growth charts should be introduced along with training of health workers. This has implications for nutritional intervention programmes, for resetting the country's targets for Millennium Development Goal 1 and for monitoring nutritional trends.
