Hazardous effects of fried potato chips on the development of retina in albino rats

Objective

To evaluate the hazardous effects of fried potato chips upon the retina of two developmental stages of the albino rats aged 7 and 14 days from parturition.

Methods

Pregnant rats were arranged into two groups: control pregnant rats and consequently their delivered newborns until reaching 7 and 14 days old from parturition and fried potato chips group in which pregnant rats at the 6th day of gestation maintained on diet formed of fried potato chips supplied from the market mixed with standard diet at a concentration of 50% per each till 7 and 14 post-partum. Three fold integrated approaches were adopted, namely, histological, ultrastructural and proteomic analysis.

Results

Histological examination of the retina of the experimental offsprings revealed many histopathological changes, including massive degeneration, vacuolization and cell loss in the ganglion cell layer, as well as general reduction in retinal size. At the ultrastructural level, the retina of experimental offsprings exhibited number of deformities, including ill differentiated and degenerated nuclear layer, malformed and vacuolated pigment epithelium with vesiculated and fragmented rough endoplasmic reticulum, degenerated outer segment of photoreceptors, as well as swollen choriocapillaris and loss of neuronal cells. Proteomic analysis of retina of the two experimental developmental stages showed variations in the expressed proteins as a result of intoxication which illustrated the adverse toxic effects of fried potato chips upon the retina.

Conclusions

It can be concluded that the effect of fried potato chips on the development of retina in rats may be due to the presence of acrylamide or its metabolite.     

Study of blood pressure profile of school children 6–15 years in a rural setting of Maharashtra

Background

High blood pressure in childhood is a major risk factor for heart disease and stroke in adulthood. There is enough evidence to suggest that the roots of essential hypertension in adults extend into childhood. There is a paucity of literature on the blood pressure measurements amongst children. This study was done to study blood pressure profile of school children in rural area of Maharashtra.

Aim & objectives

This cross sectional study was carried out to determine the prevalence of hypertension in children 6–15 years and to study the association between selected variables and blood pressure.

Material & methods

This study was done using a predesigned questionnaire and making measurements of height, BMI and Blood pressure using standardized physical instruments following standard guidelines. The data was collected and analyzed using appropriate statistical tests.

Results

The prevalence of hypertension in the study was found to be 4.4% with 3.5% in females and 5.1% in males.

Conclusion

In the study, hypertension in students was found to be significantly associated with higher BMI and with family history of hypertension. Age, height and BMI were found to correlate positively with Blood pressure levels in this study.     

Influence of testosterone replacement therapy on metabolic disorders in male patients with type 2 diabetes mellitus and androgen deficiency

Background

Multiple epidemiological studies have shown that low testosterone levels are associated with and predict the future development of type 2 diabetes mellitus and the metabolic syndrome.The aim of our study was to show the influence of testosterone replacement therapy on obesity, HbA1c level, hypertension and dyslipidemia in patients with diabetes mellitus and androgen deficiency.

Methods

One hundred and twenty-five male patients with diabetes mellitus were screened; 85 subjects aged 41 to 65 years, with BMI from 27.0 to 48.0 kg/m², were randomized in a placebo-controlled study. They also underwent a routine physical examination and selected by free testosterone examination. We divided patients into two groups: 1) treatment group, where we used diet, physical activity, patient’s antidiabetic therapy and testosterone replacement therapy; 2) placebo group, where we used diet, physical activity, patient’s antidiabetic therapy and placebo.

Results

After 6 months of treatment we repeated the diagnostic assessments: lipid profile was improved in both groups but in first group it was clinically significant. Free testosterone level increased in all groups, but in group I was clinically significant. HbA1c decreased in both groups, but in group I we obtained the best result. Leptin level after treatment was approximately the same in both groups. Also, blood pressure was reduced in both groups but results were similar.

Conclusions

Our study demonstrated that it is possible to break this metabolic vicious circle by raising testosterone levels in diabetic men with androgen deficiency. Re-instituting physiological levels of testosterone, as the study has shown, has an important role in reducing the prevalence of diabetic complications.     

Commercial off-the-shelf consumer health informatics interventions: recommendations for their design,evaluation and redesign

Objective

The goal of this paper is to describe the successful application of a use case-based evaluation approach to guide the effective design, evaluation and redesign of inexpensive, commercial, off-the-shelf consumer health informatics (CHI) interventions.

Design

Researchers developed four CHI intervention use cases representing two distinct patient populations (patients with diabetes with high blood pressure, post-bariatric surgery patients), two commercial off-the-shelf CHI applications (Microsoft HealthVault, Google Health), and related devices (blood pressure monitor, pedometer, weight scale). Three patient proxies tested each intervention for 10 days.

Measurements

The patient proxies recorded their challenges while completing use case tasks, rating the severity of each challenge based on how much it hindered their use of the intervention. Two independent evaluators categorized the challenges by human factors domain (physical, cognitive, macroergonomic).

Results

The use case-based approach resulted in the identification of 122 challenges, with 12% physical, 50% cognitive and 38% macroergonomic. Thirty-nine challenges (32%) were at least moderately severe. Nine of 22 use case tasks (41%) accounted for 72% of the challenges.

Limitations

The study used two patient proxies and addressed two specific patient populations and low-cost, off-the-shelf CHI interventions, which may not perfectly generalize to a larger number of proxies, actual patient populations, or other CHI interventions.

Conclusion

CHI designers can employ the use case-based evaluation approach to assess the fit of a CHI intervention with patients'' health work, in the context of their daily activities and environment, which would be difficult or impossible to evaluate by laboratory-based studies.     

Randomized clinical trial of a customized electronic alert requiring an affirmative response compared to a control group receiving a commercial passive CPOE alert: NSAID�Cwarfarin co-prescribing as a test case

Background

Studies that have looked at the effectiveness of computerized decision support systems to prevent drug–drug interactions have reported modest results because of low response by the providers to the automated alerts.

Objective

To evaluate, within an inpatient computerized physician order entry (CPOE) system, the incremental effectiveness of an alert that required a response from the provider, intended as a stronger intervention to prevent concurrent orders of warfarin and non-steroidal anti-inflammatory drugs (NSAIDs).

Design

Randomized clinical trial of 1963 clinicians assigned to either an intervention group receiving a customized electronic alert requiring affirmative response or a control group receiving a commercially available passive alert as part of the CPOE. The study duration was 2 August 2006 to 15 December 2007.

Measurements

Alert adherence was compared between study groups.

Results

The proportion of desired ordering responses (ie, not reordering the alert-triggering drug after firing) was lower in the intervention group (114/464 (25%) customized alerts issued) than in the control group (154/560 (28%) passive alerts firing). The adjusted OR of inappropriate ordering was 1.22 (95% CI 0.69 to 2.16).

Conclusion

A customized CPOE alert that required a provider response had no effect in reducing concomitant prescribing of NSAIDs and warfarin beyond that of the commercially available passive alert received by the control group. New CPOE alerts cannot be assumed to be effective in improving prescribing, and need evaluation.     

Underweight and overweight men have greater exercise-induced dyspnoea than normal weight men

Introduction.

Persons with high or low body mass index (BMI), involved in clinical or mechanistic trials involving exercise testing, might estimate dyspnoea differently from persons with a normal BMI.

Aims.

Our objective was to investigate the relationship between BMI and dyspnoea during exercise in normal subjects with varying BMI.

Material and methods.

A total of 37 subjects undertook progressive exercise testing. Subjects were divided into three groups: underweight (UW), normal weight (NW), and overweight (OW). Dyspnoea was estimated using the visual analogue scale (VAS). Spirometry, maximum voluntary ventilation (MVV), and respiratory muscle strength (RMS) were measured.

Results and discussion.

The intercept of the VAS/ventilation relationship was significantly higher in NW subjects compared to UW (P = 0.029) and OW subjects (P = 0.040). Relative to the OW group, FVC (P = 0.020), FEV₁ (P = 0.024), MVV (P = 0.019), and RMS (P = 0.003) were significantly decreased in the UW group. The greater levels of dyspnoea in UW subjects could possibly be due to decreased RMS. Healthy persons should aim to achieve an optimum BMI range to have the lowest exercise-induced dyspnoea.     

Impact on Quality of Life of a Telemedicine System Supporting Head and Neck Cancer Patients: A Controlled Trial During the Postoperative Period at Home

Objectives

Telemedicine applications carry the potential to enhance the quality of life of patients, but studies evaluating telemedicine applications are still scarce. The evidence regarding the effectiveness of telemedicine is limited and not yet conclusive. This study investigated whether telemedicine could be beneficial to the quality of life of cancer patients.

Design and Measurements

Between 1999 and 2002, we conducted a prospective controlled trial evaluating the effects of a telemedicine application on the quality of life of patients with cancer involving the head and neck, using quality of life questionnaires that covered 22 quality of life parameters. All patients had undergone surgery for head and neck cancer at the Erasmus MC, a tertiary university hospital in The Netherlands. Patients in the intervention group were given access to an electronic health information support system for a period of six weeks, starting at discharge from the hospital.

Results

In total, we included 145 patients in the control group and 39 in the intervention group. At 6 weeks, the end of the intervention, the intervention group had significantly improved QoL in 5 of the 22 studied parameters. Only one of these five quality of life parameters remained significantly different at 12 weeks.

Conclusions

This study adds to the sparse evidence that telemedicine may be beneficial for the quality of life of cancer patients.     

Laparoscopic Cardiomyotomy for Achalasia: A Single Unit study

Aims

Achalasia is a rare incurable neuromuscular disorder of the oesophagus. A number of treatment options are available. We reviewed our results of laparoscopic cardiomyotomy over a 30 month period.

Methods

18 patients with manometric features of achalasia underwent surgery between 2004 and 2006. Pre and postoperative weight and dysphagia scores were recorded (maximum score 45=normal, 0=complete dysphagia). Change in the Body Mass Index (BMI) was measured. Other symptoms (heartburn, epigastric pain, regurgitation, odynophagia and sleep disturbance) were scored on a 0–4 scale of increasing severity.

Results

At mean follow up of 16.2 months the mean dysphagia score was significantly improved from 7.5 to 33.9 (p<0.005). BMI was significantly increased from 22.3 to 25.8 kg/m² (p<0.05). Scores for heartburn, epigastric pain, regurgitation, odynophagia and sleep disturbance were also significantly improved. The average inpatient stay was 3.1 days and average operating time 111 minutes. One mucosal perforation occurred which was repaired intraoperatively. No patients required secondary operative intervention.

Conclusions

Laparoscopic cardiomyotomy is a safe, highly effective, minimally invasive treatment for achalasia.     

Population informatics-based system to improve osteoporosis screening in women in a primary care practice

Objective

To study the effects of using a population-based informatics system for osteoporosis screening and treatment in women aged 65 years or older.

Design

A population-based informatics system (PRECARES: PREventive CAre REminder System) was implemented to meet the needs of the workflow of a primary care practice. Patients treated in either of two sections of a primary care internal medicine department were selected for the intervention, and patients of a comparable third section served as the control group. PRECARES identified women in the intervention group who were due for osteoporosis screening on the basis of age and who had no record of previous screening in our clinical system. If these eligible patients did not have an upcoming outpatient appointment, appointment secretaries sent a letter requesting that they call to make an appointment for a dual-energy x-ray absorptiometry scan.

Measurements

At baseline and 3 months after the letters were sent, a database was used to determine the rate of osteoporosis screening in the intervention and control groups.

Results

A total of 689 patients in the intervention group were sent the letter. Three months after the letters were sent, the rate of osteoporosis screening was 76.4% (2409/3152) in the intervention group vs 69% (928/1344) in the control group (p<0.001). In the intervention group, 25% of the 689 patients responded to the letter and completed osteoporosis screening. Patients who had osteoporosis screening received appropriate treatment.

Conclusion

A population-based informatics system for primary care practice significantly improved the rate of osteoporosis screening.     

Impact of iron supplementation on schistosomiasis control in Zambian school children in a highly endemic area

Aim

To study impact of once weekly iron supplementation on praziquantel cure rate, Schistosoma haematobium reinfection, and haematological parameters in pupils aged between 9 and 15 years of age in Nchelenge district, Zambia.

Methods

Pupils in the intervention group received once weekly dose of ferrous sulphate at 200mg while those in the control received once weekly vitamin C at 100mg for up to 9 months. Both study groups received a single dose of praziquantel at baseline.

Results

S haematobium reinfection intensity was significantly lower in boys in the intervention group than in boys in the control group at 6 months (P<0.001) and 9 months (P<0.001) of supplementation. Significantly lower S haematobium reinfection intensity was found in girls in the intervention group than in girls in the control group only at 6 months of supplementation (P=0.018). Boys in the intervention group were 42% (Adjusted Risk Ratio =0.58, 95% confidence interval 0.39, 0.86) less likely to be reinfected with S haematobium than in the control group at 6 months follow up.

Conclusion

Once weekly iron supplementation can decrease S haematobium reinfection after 6 months and should be incorporated into school based schistosomiasis control programs in highly endemic areas.

Targeted screening for pediatric conditions with the CHICA system

Objective

The Child Health Improvement through Computer Automation (CHICA) system is a decision-support and electronic-medical-record system for pediatric health maintenance and disease management. The purpose of this study was to explore CHICA''s ability to screen patients for disorders that have validated screening criteria—specifically tuberculosis (TB) and iron-deficiency anemia.

Design

Children between 0 and 11 years were randomized by the CHICA system. In the intervention group, parents were asked about TB and iron-deficiency risk, and physicians received a tailored prompt. In the control group, no screens were performed, and the physician received a generic prompt about these disorders.

Results

1123 participants were randomized to the control group and 1116 participants to the intervention group. Significantly more people reported positive risk factors for iron-deficiency anemia in the intervention group (17.5% vs 3.1%, OR 6.6, 95% CI 4.5 to 9.5). In general, far fewer parents reported risk factors for TB than for iron-deficiency anemia. Again, there were significantly higher detection rates of positive risk factors in the intervention group (1.8% vs 0.8%, OR 2.3, 95% CI 1.0 to 5.0).

Limitations

It is possible that there may be more positive screens without improving outcomes. However, the guidelines are based on studies that have evaluated the questions the authors used as sensitive and specific, and there is no reason to believe that parents misunderstood them.

Conclusions

Many screening tests are risk-based, not universal, leaving physicians to determine who should have a further workup. This can be a time-consuming process. The authors demonstrated that the CHICA system performs well in assessing risk automatically for TB and iron-deficiency anemia.     

Effects of a computer-supported interactive tailored patient assessment tool on patient care, symptom distress, and patients' need for symptom management support: a randomized clinical trial

Objective

To examine the effects of a computer-assisted, interactive tailored patient assessment (ITPA) tool in oncology practice on: documented patient care, symptom distress, and patients'' need for symptom management support during treatment and rehabilitation.

Design and methods

For this repeated measures clinical trial at a university hospital in Norway, 145 patients starting treatment for leukemia or lymphoma were randomly assigned to either an intervention (n=75) or control group (n=70). Both groups used the ITPA for symptom assessments prior to inpatient and outpatient visits for up to one year. The assessment summary, which displayed patients'' self-reported symptoms, problems, and distress in rank-order of the patient''s need for support, was provided to physicians and nurses in the intervention group only but not in the control group.

Results

Significantly more symptoms were addressed in the intervention group patient charts versus those of the control group. Symptom distress in the intervention group decreased significantly over time in 11 (58%) of 19 symptom/problem categories versus 2 (10%) for the control group. Need for symptom management support over time also decreased significantly more for the intervention group than the control group in 13 (68%) symptom categories.

Conclusion

This is the first study to show that an ITPA used in an interdisciplinary oncology practice can significantly improve patient-centered care and patient outcomes, including reduced symptom distress and reduced need for symptom management support.     

Rheumatoid arthritis patients with active disease and no history of cardiac pathology have higher brain natriuretic peptide (BNP) levels than patients with inactive disease or healthy control subjects

Background

Rheumatoid arthritis (RA) is associated with increased incidence cardiac failure. It is yet unclear how much the increased incidence is secondary to ischaemic damage, or whether inflammatory cytokines might have a direct effect on the myocardium

Objectives

To establish if patients with active rheumatoid arthritis but no history of cardiac disease have higher serum levels of brain natriuretic peptide (BNP), than patients with less active RA, or disease-free controls.

Methods

90 patients with RA and 31 healthy control subjects were recruited. Each was screened to exclude previous history of cardiac disease. RA disease activity was measured using the DAS28 assessment, and other demographic, physical and laboratory tests performed. Serum BNP levels were measured in all subjects.

Results

There was no difference in the age, percentage females or BMI between the RA and control subjects. Median BNP in the RA patients was 80.0 pg/ml (IQR 38.0–132.0) compared with 48.5 (26.0–86.0) in the control subjects (p=0.017). There was a significant correlation between DAS28 and serum BNP in the RA group, r=0.37, p<0.01. RA patients were divided into three groups according to DAS28 scores. Patients with very active disease (DAS28>5.1) had significantly higher BNP levels than patients with moderately active disease (3.2ConclusionRA patients with no history of cardiac disease have higher serum BNP levels than healthy control subjects. RA patients with active RA have higher BNP levels than RA patients with moderately active or inactive disease, raising the possibility of a directly depressive effect of inflammatory cytokines on the myocardium     

Distraction Osteogenesis in Management of Mandibular Deformities

Background

The concept of Distraction Osteogenesis is applied in Maxillofacial surgery extensively in the recent past, revolutionizing the concept of management of facial deformities specially the mandible.

Methods

This article describes intra oral mandibular distractors in managing mandibular deformities in 9 cases.

Conclusion

Surgical intervention is possible in very young patients. Distraction Osteogenosis does not reduce the need for orthodontic intervention. A multifarious approach to the problem, should form the basis of treatment of mandibular deformities.Key Words: Distraction osteogenesis, Mandibular hypoplasia, Congenital deformities     

Improving completeness of electronic problem lists through clinical decision support: a randomized, controlled trial

Background

Accurate clinical problem lists are critical for patient care, clinical decision support, population reporting, quality improvement, and research. However, problem lists are often incomplete or out of date.

Objective

To determine whether a clinical alerting system, which uses inference rules to notify providers of undocumented problems, improves problem list documentation.

Study Design and Methods

Inference rules for 17 conditions were constructed and an electronic health record-based intervention was evaluated to improve problem documentation. A cluster randomized trial was conducted of 11 participating clinics affiliated with a large academic medical center, totaling 28 primary care clinical areas, with 14 receiving the intervention and 14 as controls. The intervention was a clinical alert directed to the provider that suggested adding a problem to the electronic problem list based on inference rules. The primary outcome measure was acceptance of the alert. The number of study problems added in each arm as a pre-specified secondary outcome was also assessed. Data were collected during 6-month pre-intervention (11/2009–5/2010) and intervention (5/2010–11/2010) periods.

Results

17 043 alerts were presented, of which 41.1% were accepted. In the intervention arm, providers documented significantly more study problems (adjusted OR=3.4, p<0.001), with an absolute difference of 6277 additional problems. In the intervention group, 70.4% of all study problems were added via the problem list alerts. Significant increases in problem notation were observed for 13 of 17 conditions.

Conclusion

Problem inference alerts significantly increase notation of important patient problems in primary care, which in turn has the potential to facilitate quality improvement.

Training Multidisciplinary Biomedical Informatics Students: Three Years of Experience

Objective

The European INFOBIOMED Network of Excellence ¹ recognized that a successful education program in biomedical informatics should include not only traditional teaching activities in the basic sciences but also the development of skills for working in multidisciplinary teams.

Design

A carefully developed 3-year training program for biomedical informatics students addressed these educational aspects through the following four activities: (1) an internet course database containing an overview of all Medical Informatics and BioInformatics courses, (2) a BioMedical Informatics Summer School, (3) a mobility program based on a ‘brokerage service’ which published demands and offers, including funding for research exchange projects, and (4) training challenges aimed at the development of multi-disciplinary skills.

Measurements

This paper focuses on experiences gained in the development of novel educational activities addressing work in multidisciplinary teams. The training challenges described here were evaluated by asking participants to fill out forms with Likert scale based questions. For the mobility program a needs assessment was carried out.

Results

The mobility program supported 20 exchanges which fostered new BMI research, resulted in a number of peer-reviewed publications and demonstrated the feasibility of this multidisciplinary BMI approach within the European Union. Students unanimously indicated that the training challenge experience had contributed to their understanding and appreciation of multidisciplinary teamwork.

Conclusion

The training activities undertaken in INFOBIOMED have contributed to a multi-disciplinary BMI approach. It is our hope that this work might provide an impetus for training efforts in Europe, and yield a new generation of biomedical informaticians.     

Effectiveness of Topic-specific Infobuttons: A Randomized Controlled Trial

Objective

Infobuttons are decision support tools that provide links within electronic medical record systems to relevant content in online information resources. The aim of infobuttons is to help clinicians promptly meet their information needs. The objective of this study was to determine whether infobutton links that direct to specific content topics (“topic links”) are more effective than links that point to general overview content (“nonspecific links”).

Design

Randomized controlled trial with a control and an intervention group. Clinicians in the control group had access to nonspecific links, while those in the intervention group had access to topic links.

Measurements

Infobutton session duration, number of infobutton sessions, session success rate, and the self-reported impact that the infobutton session produced on decision making.

Results

The analysis was performed on 90 subjects and 3,729 infobutton sessions. Subjects in the intervention group spent 17.4% less time seeking for information (35.5 seconds vs. 43 seconds, p = 0.008) than those in the control group. Subjects in the intervention group used infobuttons 20.5% (22 sessions vs. 17.5 sessions, p = 0.21) more often than in the control group, but the difference was not significant. The information seeking success rate was equally high in both groups (89.4% control vs. 87.2% intervention, p = 0.99). Subjects reported a high positive clinical impact (i.e., decision enhancement or knowledge update) in 62% of the sessions.

Limitations

The exclusion of users with a low frequency of infobutton use and the focus on medication-related information needs may limit the generalization of the results. The session outcomes measurement was based on clinicians'' self-assessment and therefore prone to bias.

Conclusion

The results support the hypothesis that topic links are more efficient than nonspecific links regarding the time seeking for information. It is unclear whether the statistical difference demonstrated will result in a clinically significant impact. However, the overall results confirm previous evidence that infobuttons are effective at helping clinicians to answer questions at the point of care and demonstrate a modest incremental change in the efficiency of information delivery for routine users of this tool.     

Effectiveness of an information technology intervention to improve prophylactic antibacterial use in the postoperative period

Background

A 2005 report from the Centers for Medicare and Medicaid Services and the Centers for Disease Control Surgical Infection Prevention program indicated that only 41% of prophylactic antibacterials were correctly stopped within 24 h of the end of surgery. Electronic order sets have shown promise as a means of integrating guideline information with electronic order entry systems and facilitating safer, more effective care.

Objective

The aim was to study the effectiveness of a computer-based antibacterial order set on increasing the proportion of patients who have antibacterial wound prophylaxis discontinued in the appropriate time frame.

Design

The authors conducted a quasi-experimental interrupted time-series analysis over an 8-month study period with the implementation of a computer-based order system designed to prevent excessive duration of surgical prophylaxis antibacterials.

Measurement

The primary outcome was the proportion of surgeries with antibacterials discontinued in the appropriate time frame. Additionally, we evaluated the percent of surgeries after implementation of the electronic intervention with chart documentation of infection among surgeries where the prescriber indicated the reason for antibacterial therapy was treatment.

Results

The computer-based order intervention significantly improved the proportion of surgeries with timely discontinuation of antibacterials from 38.8% to 55.7% (p<0.001) in the intervention hospital, while the control hospital remained at 56–57% (p=0.006 for the difference between treated and control hospitals). In surgeries after intervention implementation where a prescriber indicated the reason for antibacterial therapy was treatment, the prevalence of chart documented infection was only 14%.

Conclusions

A computer-based electronic order set intervention increased timely discontinuation of postoperative antibacterials.     

Impact of maternal body mass index on neonatal outcome

Introduction

Maternal body mass index has an impact on maternal and fetal pregnancy outcome. An increased maternal BMI is known to be associated with admission of the newborn to a neonatal care unit. The reasons and impact of this admission on fetal outcome, however, are unknown so far.

Objective

The aim of our study was to investigate the impact of maternal BMI on maternal and fetal pregnancy outcome with special focus on the children admitted to a neonatal care unit.

Methods

A cohort of 2049 non-diabetic mothers giving birth in the Charite university hospital was prospectively studied. The impact of maternal BMI on maternal and fetal outcome parameters was tested using multivariate regression analysis. Outcome of children admitted to a neonatal ward (n = 505) was analysed.

Results

Increased maternal BMI was associated with an increased risk for hypertensive complications, peripheral edema, caesarean section, fetal macrosomia and admission of the newborn to a neonatal care unit, whereas decreased BMI was associated with preterm birth and lower birthweight. In the neonatal ward children from obese mothers are characterized by hypoglycaemia. They need less oxygen, and exhibit a shorter stay on the neonatal ward compared to children from normal weight mothers, whereas children from underweight mothers are characterized by lower umbilical blood pH and increased incidence of death corresponding to increased prevalence of preterm birth.

Conclusion

Pregnancy outcome is worst in babies from mothers with low body mass index as compared to healthy weight mothers with respect to increased incidence of preterm birth, lower birth weight and increased neonate mortality on the neonatal ward. We demonstrate that the increased risk for neonatal admission in children from obese mothers does not necessarily indicate severe fetal impairment.     

Stress fractures—a prospective study amongst recruits

Background

Stress fracture (SF) is the single most common cause for the lost number of manpower days during training of recruits in the Armed Forces. This prospective study was undertaken with a view to develop baseline data on incidence of SF and to identify related variables.

Methods

A prospective study over a period of five years during 2004–2009 in which a total of 8,570 recruits were enrolled at the start of their training to find out the incidence and pattern of SFs.

Results

A total of 604 (7.04%, 95% CI 6.40–7.40%) out of a total of 8,570 recruits sustained SF during the study period. The majority of fractures occurred during basic training. The factors like urban residence, vegetarianism and those without prior history of physical activity were found to be associated with SF. Tibia was the commonest bone involved.

Conclusion

Prevention is undoubtedly the best approach in SF and other sports injuries. Priority should be given to individuals with good sports and physical activity background during recruitment. Intensity of training should be gradually increased during first three months (12 weeks) of training.Key Words: recruits, stress fracture
