Randomized controlled trial of day care versus hospital care of severe pneumonia in Bangladesh

OBJECTIVE

A randomized controlled trial compared day care versus hospital care management of pneumonia.

METHODS

Children 2 to 59 months of age with severe pneumonia received either day care, with antibiotic treatment, feeding, and supportive care from 8:00 am to 5:00 pm, or hospital care, with similar 24-hour treatment.

RESULTS

In 2006-2008, 360 children were assigned randomly to receive either day care or hospital care; 189 (53%) had hypoxemia, with a mean±SD oxygen saturation of 93±4%, which increased to 99±1% after oxygen therapy. The mean±SD durations of day care and hospital care were 7.1±2.3 and 6.5±2.8 days, respectively. Successful management was possible for 156 (87.7% [95% confidence interval [CI]: 80.9%-90.9%]) of 180 children in the day care group and 173 (96.1% [95% CI: 92.2%-98.1%]) of 180 children in the hospital care group (P=.001). Twenty-three children in the day care group (12.8% [95% CI: 8.7%-18.4%] and 4 children in the hospital care group (2.2% [95% CI: 0.9%-5.6%] required referral to hospitals (P<.001). During the follow-up period, 22 children in the day care group (14.1% [95% CI: 9.5%-20.4%]) and 11 children in the hospital care group (6.4% [95% CI: 3.6%-11%]) required readmission to hospitals (P=.01). The estimated costs per child treated successfully at the clinic and the hospital were US$114 and US$178, respectively.

CONCLUSION

Severe childhood pneumonia without severe malnutrition can be successfully managed at day care clinics, except for children with hypoxemia who require prolonged oxygen therapy.

Trends of diabetes according to body mass index levels in Iran: results of the national Surveys of Risk Factors of Non-Communicable Diseases (1999-2007)

AIMS

The prevalence of diabetes is increasing dramatically worldwide. Less is known about whether this trend is similar among obese and lean individuals.

METHODS

We analysed the data sets of three cross-sectional national surveys in adults aged 25-64 years: the National Health Survey-1999 (n=21,576), and the national Surveys of Risk Factors of Non-Communicable Diseases (SuRFNCD)-2005 (n=70,981) and SuRFNCD-2007 (n=4233). Diagnosed diabetes was ascertained, and height and weight were measured in all surveys. In SuRFNCD-2005 and SuRFNCD-2007, fasting plasma glucose was used to identify subjects with newly diagnosed diabetes (≥ 7 mmol/l) and impaired fasting glucose (5.6 - 6.9 mmol/l) among individuals not reporting diabetes.

RESULTS

The prevalence of diagnosed diabetes (after adjustment for age, sex and residential area) was 2.5, 4.0 and 4.6% in 1999, 2005 and 2007, respectively. The total prevalence of diabetes increased from 7.7% in 2005 to 8.7% in 2007, about half of which was attributed to newly diagnosed disease (in both surveys). The prevalence of diabetes increased in all categories of obesity, with the most evident trend being among subjects with body mass index <25 kg/m(2) .

CONCLUSIONS

The prevalence of diabetes among Iranian adults has increased more than 1.8-fold in a period of only 8 years since 1999. This is the first report from Iran, and urgent measures need to be taken in order to prevent the progression and worsening of the problem and emergence of its undesired consequences.

Work stress and hair cortisol levels among workers in a Bangladeshi ready-made garment factory - Results from a cross-sectional study

Evidence on the association of work stress with cortisol levels is inconsistent and mostly stems from Western countries, with limited generalizability to other regions of the world. These inconsistencies may partly be due to methodological limitations associated with the measurement of cortisol secretion in saliva, serum or urine. The present study set out to explore associations of work stress with long-term integrated cortisol levels in hair among 175 workers of an export oriented ready-made garment (RMG) factory in Dhaka, Bangladesh. Work-related demands (WD), interpersonal resources (IR) and work-related values (WV) were assessed using a psychometrically evaluated interview. WD consisted of four items on physical demands, time pressure, worries about mistakes and exposure to abusive language. IR comprised five items addressing support, recognition, adequate payment, workers' trust in the management, and the management's trust in workers, as perceived by the workers. WV captured job security, promotion prospects and job latitude by three items. Hair cortisol concentrations (HCC) were analyzed by liquid chromatography-mass spectrometry. Stepwise multivariable linear regression models (backward elimination of predictors) were used to estimate associations of HCC with the three work stress components. For significant work stress component(s), further multivariable linear regression analyses were conducted to explore whether, and if so, which individual item(s) contributed most. The mean HCC equaled 3.27 (SD 2.58) pg/mg. HCC were found to be significantly associated with WV (beta=0.209, p=0.021). Additional analyses of the three WV items revealed that this association was largely driven the item on "promotion prospects" (beta=0.230, p=0.007) implying that the perception of good promotion prospects was associated with higher HCC. The finding of elevated HCC with good promotion prospects may initially seem counter-intuitive, but is supported by research documenting that job promotion may result in poorer mental well-being. Moreover, being promoted in the Bangladeshi RMG industry may represent a stressful experience: job promotions are rare in this setting and are associated with the need to meet exceptional job-related demands. Further research from ethnic and culturally diverse occupational settings is needed to test this hypothesis, to shed light on the reproducibility of our findings and to improve our understanding of the psychobiological implications of psychosocial working conditions across cultures and contexts.

Day-care management of children with severe malnutrition in an urban health clinic in Dhaka, Bangladesh

Management of severely malnourished children with associated complications relies on hospital-based treatment. Implementation of a standardized protocol at the Dhaka Hospital, ICDDR,B reduced case fatality approximately 50%. We developed and prospectively evaluated a day-care clinic approach that provided antibiotics, micronutrients and feeding during the day with continued care by parents at home at night as an alternative to hospitalization. Severely malnourished children aged 6-23 months denied admission to hospital were enrolled at Radda Clinic, Dhaka and received protocolized management with antibiotics, micronutrients and milk-based diet from 8:00 am to 5:00 pm each day, while mothers were educated on continuation of care at home. They were transitioned to the day-care nutrition rehabilitation (NR) unit of Radda Clinic following resolution of acute illness, received NR diet (Khichuri, halwa and milk-based) daily until children attained 80% weight-for-length. From February 2001 to November 2003, 264 children were enrolled; 52% were boys and 78%, 21% and 1% had marasmus, marasmus-kwashiorkor and kwashiorkor, respectively. Only 13% had severe malnutrition alone while 35% had pneumonia, 35% had diarrhea and 17% had both pneumonia and diarrhea. The mean (SD) duration of acute and NR phases were 8 (4) and 14 (13) days, respectively. Children gained weight [mean (SD) g/kg day] more rapidly during acute 10 (7) than NR phase 6 (5). Successful management was possible in 82% (95% CI 77-86%) children, 12% discontinued treatment and 6% referred to hospitals. Only one child died during NR phase. Severely malnourished children can be successfully managed at existing day-care clinics using a protocolized approach.

Efficacy of partially hydrolyzed guar gum (PHGG) supplemented modified oral rehydration solution in the treatment of severely malnourished children with watery diarrhoea: a randomised double-blind controlled trial

OBJECTIVES

To examine whether PHGG added ORS reduce duration of diarrhoea, stool output and enhance weight gain.

METHODS

In a double-blind controlled clinical trial, 126 malnourished children (weight for length/weight for age < -3 Z-score with or without pedal edema), aged 6 - 36 months with acute diarrhoea <7 days were studied in two treatment groups; 63 received modified WHO ORS (Na 75, K 40, Cl 87, citrate 7, glucose 90 mmol/L) with PHGG 15 g/L (study group); 63 received modified WHO ORS without PHGG (control). Other treatments were similar in both groups. The study protocol was approved by Ethics Committee of icddr,b; the study was carried out at the Dhaka Hospital.

RESULTS

The mean duration of diarrhoea (h) was significantly shorter in children of the study group (Study vs. control, mean ± SD, 57 ± 31 vs. 75 ± 39, p = 0.01). Although there was a trend in stool weight reduction in children receiving ORS with PHGG (study vs. control, stool weight (g), mean ± SD; 1(st) 24 hour, 854.03 ± 532.15 vs. 949.11 ± 544.33, p = 0.32; 2(nd) 24 hour, 579.84 ± 466.01 vs. 761.26 ± 631.64, p = 0.069; 3(rd) 24 hour, 385.87 ± 454.09 vs. 495.73 ± 487.61, p = 0.196), especially in 2(nd) 24 h period, the difference was not statistically significant. The mean time (day) to attain weight for length 80% of NCHS median without edema was significantly shorter in the study group (study vs. control, mean ± SD, 4.5 ± 2.6 vs. 5.7 ± 2.8, p = 0.027).

CONCLUSION

PHGG added to ORS substantially reduced duration of diarrhoea. It also enhanced weight gain. Further studies might substantiate to establish its beneficial effect.

Insulin resistance is an independent correlate of increased urine albumin excretion: a cross-sectional study in Iranian Type 2 diabetic patients

AIMS

To assess the association of insulin resistance with increased urinary albumin excretion (UAE) in a cohort of Iranian Type 2 diabetic patients.

METHODS

Three hundred and sixty-one men and 472 women with Type 2 diabetes were enrolled from three different outpatient clinics (Tehran, Iran) during the period 2005-2008. Patients with obstructive uropathy, severe heart failure, liver disease, cancer, autoimmune disease and macroalbuminuria were not included. Microalbuminuria (MA; defined as UAE >or= 30 mg/day) was found in 242 (29.1%) patients; 591 (70.9%) subjects had normoalbuminuria (UAE < 30 mg/day). Insulin resistance was assessed using homeostasis model assessment of insulin resistance (HOMA-IR).

RESULTS

HOMA-IR index values were higher in subjects with MA than those with normoalbuminuria (P < 0.00001). Adjusted values (for age, sex and duration of diabetes) of UAE and HOMA-IR were 11.81 +/- 7.51 (mg/day) and 3.30 +/- 2.21 in normoalbuminuric and 75.36 +/- 55.57 (mg/day) and 4.98 +/- 3.22 in the MA group, respectively (P < 0.00001 for all). Multiple regression analysis showed that UAE was predicted by HOMA-IR, independently of age, duration of diagnosed diabetes, triglycerides, waist circumference, metabolic control, blood pressure and related treatments (P < 0.00001). When patients were categorized into quartiles of HOMA-IR, those of the fourth quartile (i.e. the most insulin resistant) were at a higher risk of increased UAE than other quartiles [odds ratio (OR) 3.7 (95% confidence intervals 2.7-6.2)].

CONCLUSIONS

In Iranian Type 2 diabetic patients, albuminuria was strongly associated with insulin resistance. HOMA-IR is an independent predictor of UAE.

Evaluation of faecal occult blood test and lactoferrin latex agglutination test in screening hospitalized patients for diagnosing inflammatory and non-inflammatory diarrhoea in Dhaka, Bangladesh

BACKGROUND

Inflammatory diarrhoea (ID) resulting from Shigella, Salmonella, Campylobacter and Entamoeba histolytica requires specific diagnosis for therapy. Differentiation between ID and non-inflammatory diarrhoea (NID) is often not clinically possible. A faecal occult blood test (FOBT) correlates with faecal leucocytes. Lactoferrin indicates an inflammatory process as a marker for faecal leucocytes. We evaluated diagnostic values of lactoferrin latex agglutination test (LT) either alone or in combination with FOBT, correlating with stool microscopy and microbiology in differentiating ID from NID.

METHODS

The study population constituted patients enrolled in 2% systematic sampling of patients under Diarrhoeal Disease Surveillance System of Dhaka Hospital, ICDDR,B.

RESULTS

Between July and November 2002, 594 patients were enrolled; evaluation of FOBT and LT were done in 448/594 (75%) patients from whom either a single enteropathogen (315/594, 53%) or no pathogen (133/594, 22%) were identified and 146 were excluded for multiple pathogens. Invasive and non-invasive pathogens were isolated from 24% and 76% of the patients. FOBT and LT were positive in 40% and 39% of the samples. The sensitivities, specificities, PPVs, NPVs, and accuracies of FOBT were 55, 63, 24, 87 and 62%, and LT were 52, 64, 23, 86 and 62%, respectively.

CONCLUSION

FOBT and LT are not useful in differentiating ID from NID in diarrhoeal patients in Dhaka, Bangladesh.

Observational follow-up study following two cohorts of children with severe pneumonia after discharge from day care clinic/hospital in Dhaka, Bangladesh

OBJECTIVES

To compare the features of relapse, morbidity, mortality and re-hospitalisation following successful discharge after severe pneumonia in children between a day care group and a hospital group and to explore the predictors of failures during 3 months of follow-up.

DESIGN

An observational study following two cohorts of children with severe pneumonia for 3 months after discharge from hospital/clinic.

SETTING

Day care was provided at the Radda Clinic and hospital care at a hospital in Dhaka, Bangladesh.

PARTICIPANTS

Children aged 2-59 months with severe pneumonia attending the clinic/hospital who survived to discharge.

INTERVENTION

No intervention was done except providing some medications for minor illnesses, if indicated.

PRIMARY OUTCOME MEASURES

The primary outcome measures were the proportion of successes and failures of day care at follow-up visits as determined by estimating the OR with 95% CI in comparison to hospital care.

RESULTS

The authors enrolled 360 children with a mean (SD) age of 8 (7) months, 81% were infants and 61% were men. The follow-up compliance dropped from 95% at first to 85% at sixth visit. The common morbidities during the follow-up period included cough (28%), fever (17%), diarrhoea (9%) and rapid breathing (7%). During the follow-up period, significantly more day care children (n=22 (OR 12.2 (95% CI 8.2-17.8))) required re-hospitalisation after completion of initial day care compared with initial hospital care group (n=11 (OR 6.1 (95% CI 3.4-10.6))). The predictors for failure were associated with tachycardia, tachypnoea and hypoxaemia on admission and prolonged duration of stay.

CONCLUSIONS

There are considerable morbidities in children discharged following treatment of severe pneumonia like cough, fever, rapid breathing and diarrhoea during 3-month period. The findings indicate the importance of follow-up for early detection of medical problems and their management to reduce the risk of death. Establishment of an effective community follow-up would be ideal to address the problem of 'non-compliance with follow-up'.

TRIAL REGISTRATION

The original randomised control trial comparing day care with hospital care was registered at http://www.clinicaltrials.gov (identifier NCT00455468).

Does the Age of Sudden Cardiac Death in Family Members Matter in Brugada Syndrome?

Background Brugada syndrome is an inherited cardiac channelopathy associated with major arrhythmic events (MAEs). The presence of a positive family history of sudden cardiac death (SCD) as a risk predictor of MAE remains controversial. We aimed to examine the association between family history of SCD and MAEs stratified by age of SCD with a systematic review and meta-analysis. Methods and Results We searched the databases of MEDLINE and EMBASE from January 1992 to January 2020. Data from each study were combined using the random-effects model. Fitted metaregression was performed to evaluate the association between the age of SCD in families and the risk of MAE. Twenty-two studies from 2004 to 2019 were included in this meta-analysis involving 3386 patients with Brugada syndrome. The overall family history of SCD was not associated with increased risk of MAE in Brugada syndrome (pooled odds ratio [OR], 1.11; 95% CI, 0.82-1.51; P=0.489, I²=45.0%). However, a history of SCD in family members of age younger than 40 years of age did increase the risk of MAE by ≈2-fold (pooled OR, 2.03; 95% CI, 1.11-3.73; P=0.022, I²=0.0%). When stratified by the age of cut point at 50, 45, 40, and 35 years old, a history of SCD in younger family member was significantly associated with a higher risk of MAE (pooled OR, 0.49, 1.30, 1.51, and 2.97, respectively; P=0.046). Conclusions A history of SCD among family members of age younger than 40 years was associated with a higher risk of MAE.

Hyperimmune bovine colostrum in the treatment of shigellosis in children: a double-blind, randomized, controlled trial

Immunological approaches have been considered as an alternative therapeutic option for the treatment of enteric infections over the past few years. Hyperimmune bovine colostrum (HBC) is a potentially innovative immunological option in the management of shigellosis together with traditional antibiotic therapy. Children aged 1-12 y with a history of bloody mucoid diarrhoea of less than 5 d duration were enrolled after their stool specimen was found to be positive for Shigella dysenteriae type I antigen by a rapid diagnostic fluorescent antibody staining test. They were randomized to receive either HBC containing very high titres of antibody against S. dysenteriae type I antigen or bovine colostrum (BC) without any antibody. The study group received 100 ml of HBC three times a day orally for 3 d and control group received BC. Children also received pivmecillinam in a dose of 50 mg kg(-1) d(-1) in four divided doses orally for 5 d. Admission characteristics of the 34 children in the HBC group and 35 in the BC group were comparable. No significant differences were observed in duration of diarrhoea, fever, anorexia, abdominal pain, tenesmus, stool frequency or visible blood in the stool between the groups. Two (6%) children in the study and five (14%) in the control group remained stool culture positive for S. dysenteriae type 1, even after 5 d of sensitive antimicrobial therapy.

CONCLUSION

The results indicate that HBC as an adjuvant is unable to show any beneficial effect in reducing the stool frequency, duration or severity of childhood shigellosis due to S. dysenteriae type I infection.

L-isoleucine-supplemented oral rehydration solution in the treatment of acute diarrhoea in children: a randomized controlled trial

Antimicrobial peptides represent an important component of the innate immune defenses of living organisms, including humans. They are broad-spectrum surface-acting agents secreted by the epithelial cells of the body in response to infection. Recently, L-isoleucine and its analogues have been found to induce antimicrobial peptides. The objectives of the study were to examine if addition of L-isoleucine to oral rehydration salts (ORS) solution would reduce stool output and/or duration of acute diarrhoea in children and induce antimicrobial peptides in intestine. This double-blind randomized controlled trial was conducted at the Dhaka Hospital of ICDDR,B. Fifty male children, aged 6-36 months, with acute diarrhoea and some dehydration, attending the hospital, were included in the study. Twenty-five children received L-isoleucine (2 g/L)-added ORS (study), and 25 received ORS without L-isoleucine (control). Stool weight, ORS intake, and duration of diarrhoea were the primary outcomes. There was a trend in reduction in mean +/- standard deviation (SD) daily stool output (g) of children in the L-isoleucine group from day 2 but it was significant on day 3 (388 +/- 261 vs. 653 +/- 446; the difference between mean [95% confidence interval (CI) (-)265 (-509, -20); p = 0.035]. Although the cumulative stool output from day 1 to day 3 reduced by 26% in the isoleucine group, it was not significant. Also, there was a trend in reduction in the mean +/- SD intake of ORS solution (mL) in the L-isoleucine group but it was significant only on day 1 (410 +/- 169 vs. 564 +/- 301), the difference between mean (95% CI) (-)154 (-288, -18); p = 0.04. The duration (hours) of diarrhoea was similar in both the groups. A gradual increase in stool concentrations of beta-defensin 2 and 3 was noted but they were not significantly different between the groups. L-isoleucine-supplemented ORS might be beneficial in reducing stool output and ORS intake in children with acute watery diarrhoea. A further study is warranted to substantiate the therapeutic effect of L-isoleucine.

Uterine myometrium as a cell patch as an alternative graft for transplantation to infarcted cardiac myocardium: a preliminary study

PURPOSE

Currently, only a small fraction of patients are able to receive reperfusion therapy for myocardial infarctions. We hypothesize that myometrial cell patch transplantation could be an alternative approach for the treatment of myocardial infarction.

DESIGN

We performed a preliminary study to determine the feasibility of this novel therapeutic approach in a rabbit model.

PROCEDURES

Six adult female New Zealand rabbits were used. Myocardial infarction was induced by left anterior descending artery ligation. A segment of uterus was removed via a laparotomy incision, and this uterine segment was transplanted as an autologous graft over the infarcted myocardium, which was then reinforced by greater omentum. Statistical methods and outcome measures: Hemodynamic measurements and histological studies.

MAIN FINDINGS

All uterine myometrial patches survived in the test animals. Fluoroscopic hemodynamic measurements were made for ejection fractions at 8 weeks after the application of the uterine patch. Histological study demonstrated well-healed myometrial-myocardium junctions with minimum scar tissue. Angiogenesis occurred in the transplanted myometrium. Connexin 43 expression was demonstrated in the transplanted patches.

CONCLUSION

Our noncontrolled preliminary rabbit experiments indicate that patches of uterine myometrium reinforced by greater omentum can be used as autologous transplant therapy for infracted myocardium. This is an innovative technique that could lead to future treatment for individuals who may suffer from an infarcted myocardium and may not be eligible for traditional reperfusion therapy.

Early feeding of an energy dense diet during acute shigellosis enhances growth in malnourished children

In a controlled clinical trial, we examined the effect of the short-term feeding of an energy-dense milk cereal formula in malnourished children with clinically severe dysentery due to acute shigellosis. Seventy-five malnourished children, aged 12-48 mo, passing blood or blood with mucous in the stool for < or = 96 h, were offered a hospital diet. In addition, study children (n = 36) were offered a milk-cereal formula with an energy of 5 kJ/g (an 11% protein diet); similarly, control children (n = 39) were offered a milk-cereal formula with an energy content of 2.5 kJ/g (an 11% protein diet). Patients were admitted to the metabolic ward of the Clinical Research and Service Centre, Dhaka, at the International Centre for Diarrhoeal Disease Research, Bangladesh. Patients were studied for 10 hospital days and were then followed up at home after 30 d. After 10 d of dietary intervention, children in the study group had a significantly greater increase vs. controls in weight-for-age (6 vs. 3%, P < 0.001) and in weight-for-height (7 vs. 3%, P < 0.001). Serum prealbumin concentrations were significantly higher (study vs. control) after 5 d (0.214 vs. 0.170 g/L, P = 0.01) and after 10 d (0.244 vs. 0.193 g/L, P = 0.006) of the study. Greater weight-for-age was sustained at home 1 mo after discharge (8 vs. 5%, P = 0.005) from the hospital. Similarly, higher weight-for-height was sustained 1 mo after discharge (8 vs. 5%, P = 0.01). During their stay at home, there was no dietary intervention. The results of this study suggest that short-term feeding of an energy-dense diet enhances growth in malnourished children with acute dysentery due to shigellosis.

Clinical signs of radiologic pneumonia in under-five hypokalemic diarrheal children admitted to an urban hospital in bangladesh

Background

Clinical signs of pneumonia are often veiled in under-five diarrheal children presenting with hypokalemia, making clinical diagnosis of pneumonia very difficult in such population. However, there is no published report that describes the influences of hypokalemia on the clinical signs of pneumonia in diarrheal children. Our objective was to assess the influences of hypokalemia, and their outcome in such children.

Methods

We prospectively enrolled all under-five diarrheal children (n = 180) admitted to the Special Care Ward of the Dhaka Hospital of icddr,b from September-December 2007 with radiological pneumonia who also had their serum potassium estimated. We compared the clinical features and outcome of the diarrheal children having pneumonia with (cases = 55) and without hypokalemia (controls = 125).

Results

The case-fatality among the cases was 2 times higher compared to the controls, but the difference was not statistically significant (p = 0.202). In logistic regression analysis, after adjusting for potential confounders such as age of the patient, clinical dehydration, severe wasting, abnormally sleepy, lower chest wall in-drawing, nasal flaring and inability to drink on admission, under-five diarrheal children with pneumonia who presented with nutritional edema had 3 times more risk to have hypokalemia compared to those without nutritional edema (OR = 2.76, 95% CI = 1.01–7.51) and these hypokalemic children were 64% less likely to present with fast breathing (OR = 0.36, 95% CI = 0.17–0.74).

Conclusion and significance

The results of our analysis are simple but may have great public health implications and underscore the importance of diligent assessment for pneumonia in under-five diarrheal children having risk of hypokalemia as in children with nutritional edema even in absence of fast breathing, a useful sign of pneumonia. This may help for early initiation of first dose of parental antibiotics along with potassium supplementation before referral to tertiary hospitals by health workers to combat probability of deaths in such population especially in resource limited settings.

Trends in Prevalence of Diagnosed Ocular Disease and Utilization of Eye Care Services in American Veterans

PURPOSE

To assess trends in prevalence of diagnosed ocular disease and use of eye care services in the Veterans Affairs (VA) health care system.

DESIGN

Prevalence study.

METHODS

We performed a retrospective study of all eligible veterans in the VA Capitol Health Care Network from 2007 to 2011. The VA database was used to abstract demographic and socioeconomic variables, including age, race, sex, marital status, service connection, prescription copay, homelessness, and VA facility. Primary outcome measures were the prevalence of diagnosed ocular disease and use of eye care. Ocular diagnoses were determined by International Classification of Diseases, 9th revision codes and use by prescription medication fills, visits to eye care clinics, and cataract surgery frequency.

RESULTS

The average age of veterans ranged from 59.8-60.9, most veterans were male (88.1-89.8%), and there was a high proportion of African Americans (29.5-30%). The prevalence of all ocular diagnoses increased from 20.5% in 2007 to 23.3% in 2011 (P < .01), a 13.7% increase. Similarly, the prevalence of diagnosed cataract increased by 35.7% (P = .02) from 7.1% in 2007 to 9.6% in 2011. Diagnosed glaucoma prevalence increased by 9.4% (P = .03) from 6.7 to 7.4%. The percent of patients seen in eye clinics increased 11.6%% in the 5-year study period to 24.0% in fiscal year 2011 (P = .05). The use of ophthalmic medications increased 20% (P < .01). The rate of cataract surgery did not change significantly during the study period.

CONCLUSIONS

The prevalence of diagnosed eye conditions among American Veterans is increasing, as is the use of eye care services. Cataract surgery rates did not increase, which may indicate a need to increase availability of these services.

Randomised trial showed that rapid rehydration of severely malnourished children with dehydrating diarrhoea was as safe and effective as slow rehydration

AIM

This study evaluated the effectiveness and safety of rapid and slow rehydration in children aged 6-60 months with dehydrating diarrhoea and severe malnutrition.

METHODS

A randomised controlled trial was conducted from July 2011 to March 2014 at the International Centre for Diarrhoeal Disease Research Bangladesh. We included children with weight for age and, or, weight for length Z-scores of less than -3 or with bipedal oedema and acute diarrhoea with severe dehydration. The children received intravenous fluid at different rates: 105 rapidly over six hours and 103 slowly over the 12 hours recommended by the World Health Organization.

RESULTS

All the children were successfully rehydrated. The admittance weights were similar for the slow and rapid groups: 8.4 kg and 8.3 kg. After 24 hours, the mean percentage weight gain was 8.5% and 9.0%, respectively. This confirmed that most of the children had been suffering from severe dehydration on admission. The respective proportions of children who received unscheduled intravenous fluid were 18% and 17%. None developed fluid overload or heart failure and most recovered normal renal function after rehydration.

CONCLUSION

Rapid rehydration saved time, was as safe as slow rehydration and was a better option for dehydrating diarrhoea and severe malnutrition.

Prevalence of diagnosed ocular disease in veterans with serious mental illness

OBJECTIVE

To compare the prevalence of diagnosed ocular disease and eye disease treatment between Veteran's Administration (VA) patients with and without serious mental illness (SMI).

METHODS

Retrospective comparison of diagnosed ocular disease and treatment prevalence among patients with and without diagnosed SMI in fiscal year 2011 in the VA Capitol Health Care System (VISN 5).

RESULTS

We identified 6462 VA patients with SMI and 137,933 without SMI. The prevalence of diagnosed ocular disease was 22.7% in SMI patients and 35.4% in non-SMI patients (P<.001). Those with SMI had a higher prevalence of glaucoma (10.2% vs. 7.1%, P<.0001), cataract (12.6% vs. 9.2%, P<.0001) and dry eye (4.0% vs. 2.7%, P<.0001). Less than half (34.3%) of SMI subjects had been seen in ophthalmology or optometry vs. 23.0% of controls (P<.0001).

CONCLUSION

VA patients with SMI have a greater prevalence of diagnosed ocular disease, particularly cataract, glaucoma and dry eye. While SMI patients utilize eye care services at a higher rate than the general VA population, the majority of subjects with SMI do not get recommended annual eye examinations. More consistent annual ocular screening among VA patients with SMI may be indicated.
