The impact of intrapartum and immediate post-partum complications and newborn care practices on breastfeeding initiation in Ethiopia: A prospective cohort study.

This study aimed to investigate the impact of intrapartum and post-partum complications and newborn care practices on early initiation of breastfeeding (EIBF). Data for the study came from a prospective cohort study in Ethiopia that recruited and followed pregnant and post-partum women from 2019 to 2021. Resident enumerators conducted interviews at enrolment in 2019 and follow-ups at 6 weeks, 6 months and 1 year post-partum. The present analysis is based on data from the baseline survey and 6 weeks follow-up. Multivariable logistic regression was used to estimate the effects of newborn care practices and intrapartum and post- partum complications on EIBF (the proportion of newborns who initiated breastfeeding within the first hour of birth). Overall, 2660 mother-infant pairs were included in this analysis. After adjustment, EIBF was less likely among women who experienced intrapartum haemorrhage (adjusted odds ratio [AOR]: 0.76, 95% confidence interval [CI]: 0.59-0.97), malpresentation (AOR: 0.46, 95% CI: 0.30-0.72) and convulsions (AOR: 0.48, 95% CI: 0.34-0.66) during childbirth. Mother-newborn skin-to-skin contact increased the likelihood of EIBF (AOR: 1.47, 95% CI: 1.11-1.94). Women who experienced post-partum haemorrhage (AOR: 0.63, 95% CI: 0.47-0.84), retained placenta for more than 30 min (AOR: 0.36, 95% CI: 0.24-0.52) and convulsions after delivery (AOR: 0.57, 95% CI: 0.41-0.79) were less likely to initiate breastfeeding early. Also, women who had a caesarean birth (AOR: 0.28, 95% CI: 0.18-0.41), delivered outside of a healthcare facility (AOR: 0.70, 95% CI: 0.50-0.99) or had twin birth (AOR: 0.43, 95% CI: 0.22-0.85) were less likely to initiate breastfeeding early. Skin-to-skin contact should be encouraged whenever possible, and women with obstetric complications should be encouraged and supported to initiate breastfeeding early.

Assessment of the current D-dimer cutoff point in pulmonary embolism workup at a single institution: Retrospective study.

Background: The currently used D-dimer (DD) cutoff point is associated with a large number of negative CT-pulmonary angiographies (CTPA). We hypothesized presence of deficiency in the current cutoff and a need to look for a better DD threshold. Materials and Methods: We conducted a retrospective medical records analysis of all patients who had a CTPA as part of pulmonary embolism (PE) workup over a 1-year period. All emergency room (ER) patients who had DD assay checked prior to CTPA were included in the analysis. We assessed our institutional cutoff point and tried to test other presumptive DD thresholds retrospectively. Results: At our institution 1591 CTPA were performed in 2014, with 1220 scans (77%) performed in the ER. DD test was ordered prior to CTPA imaging in 238 ER patients (19.5%) as part of the PE workup. PE was diagnosed in 14 cases (6%). The sensitivity and specificity of the currently used DD cutoff (0.5 mcg/mL) were found to be 100% and 13%, respectively. Shifting the cutoff value from 0.5 to 0.85 mcg/mL would result in a significant increase in the specificity from 13% to 51% while maintaining the same sensitivity of 100%. This would make theoretically 84 CTPA scans, corresponding to 35% of CTPA imaging, unnecessary because DD would be considered negative based on this presumptive threshold. Conclusions: Our results suggest a significant deficiency in the institutional DD cutoff point with the need to find a better threshold through a large multicenter prospective trial to minimize unnecessary CTPA scans and to improve patient safety.

The peculiar size and temperature dependence of water diffusion in carbon nanotubes studied with 2D NMR diffusion-relaxation D -T 2eff spectroscopy.

It is well known that water inside hydrophobic nano-channels diffuses faster than bulk water. Recent theoretical studies have shown that this enhancement depends on the size of the hydrophobic nanochannels. However, experimental evidence of this dependence is lacking. Here, by combining two-dimensional nuclear magnetic resonance diffusion-relaxation ( D - T 2 e f f ) spectroscopy in the stray field of a superconducting magnet and molecular dynamics simulations, we analyze the size dependence of water dynamics inside Carbon Nanotubes (CNTs) of different diameters ( 1.1 - 6.0 nm), in the temperature range of 265 - 305 K. Depending on the CNT diameter, the nanotube water is shown to resolve in two or more tubular components acquiring different self-diffusion coefficients. Most notably, a favorable CNT diameter range ( 3.0 - 4.5 nm) is experimentally verified for the first time, in which water molecule dynamics at the center of the CNTs exhibits distinctly non-Arrhenius behavior, characterized by ultrafast diffusion and extraordinary fragility, a result of significant importance in the efforts to understand water behavior in hydrophobic nanochannels.

Krukenberg's tumour.

BACKGROUND: Krukenburg's tumour, a metastatic cancer to the ovary can pose difficulties in early diagnosis. The paucity of reports from our environment coupled with the difficulties we encountered makes it imperative that we report this case. METHODS: We present a 32-year-old lady who presented with mucoid and bloody diarrhoea associated with menstrual irregularity, weight loss and lower abdominal pains 2 years after surgical treatment for gastric cancer. Literature on Krukenburg's tumour was also reviewed. RESULTS: While serum level of CEA was found to be elevated and colonoscopy showed an ulcerated mass obliterating the lumen of the sigmoid colon, abdominal CT scan revealed bilateral adnexal masses. The histology of the colonic lesion showed signet ring carcinoma while the enlarged ovaries turned out to have evidence of metastatic adenocarcinoma. CONCLUSION: Early diagnosis of KT can be difficult. Periodic surveillance is, therefore, essential especially in those who have had a gastrointestinal malignancy.

Dietary adherence and weight loss success among overweight women: results from the A TO Z weight loss study.

BACKGROUND: Dietary adherence has been implicated as an important factor in the success of dieting strategies; however, studies assessing and investigating its association with weight loss success are scarce. OBJECTIVE: We aimed to document the level of dietary adherence using measured diet data and to examine its association with weight loss success. DESIGN: Secondary analysis was performed using data from 181 free-living overweight/obese women (mean+/-s.d. age=43+/-5 years, body mass index=31+/-4 kg m(-2)) participating in a 1-year randomized clinical trial (the A TO Z study) comparing popular weight loss diets (Atkins, Zone and Ornish). Participants' dietary adherence was assessed as the difference between their respective assigned diet's recommended macronutrient goals and their self-reported intake. Association between dietary adherence and 12-month weight change was computed using Spearman's correlations. Differences in baseline characteristics and macronutrient intake between the most and least adherent tertiles for diet groups were compared using t-tests. RESULTS: Within each diet group, adherence score was significantly correlated with 12-month weight change (Atkins, r(s)=0.42, P=0.0003; Zone, r(s)=0.34, P=0.009 and Ornish, r(s)=0.38, P=0.004). Twelve-month weight change in the most vs least adherent tertiles, respectively, was -8.3+/-5.6 vs -1.9+/-5.8 kg, P=0.0006 (Atkins); -3.7+/-6.3 vs -0.4+/-6.8 kg, P=0.12 (Zone) and -6.5+/-6.8 vs -1.7+/-7.9 kg, P=0.06 (Ornish). CONCLUSIONS: Regardless of assigned diet groups, 12-month weight change was greater in the most adherent compared to the least adherent tertiles. These results suggest that strategies to increase adherence may deserve more emphasis than the specific macronutrient composition of the weight loss diet itself in supporting successful weight loss.

Giant and complicated subcutaneous lipoma of the neck.

BACKGROUND: Although lipomas around the head and neck region are not uncommon, giant lipomas around the neck are rare. OBJECTIVE: To report the case of a long standing giant lipoma of the neck which was managed easily by simple surgical excision. CASE REPORT: A case of giant subcutaneous lipoma of the neck is reported in a 70 year old woman who presented with dragging sensation and bleeding from the site of pressure ulceration as the major complaint. The patient was evaluated and definitive diagnosis was arrived at using Fine Needle Aspiration Cytology (FNAC). She had a successful Surgical excision and was subsequently discharged but never came back for follow up. CONCLUSION: Lipoma should always be considered in the differential diagnosis of pedunculated lesions around the neck.

Non-cirrhotic portal vein thrombosis, an uncommon cause of portal hypertension - a case report.

Most cases of portal hypertension follow chronic liver disease (cirrhosis) while non cirrhotic causes are occasionally seen. A case of portal hypertension secondary to non-cirrhotic portal vein thrombosis is reported. The patient was managed at the Aminu Kano Teaching Hospital Kano, Nigeria in the year 2006. She presented with recurrent massive upper gastrointestinal bleeding and was resuscitated, followed by clinical, radiological and endoscopic evaluation. She had massive splenomegaly and grade four oesophageal varices with evidence of recent bleed. There were, however, no other stigmata of chronic liver disease or portal hypertension. Abdominal computed tomography scan confirmed portal vein thrombosis. Splenectomy and ligation of short gastric veins was performed and the patient has not had any repeat episode of haematemesis or malaena six months post surgery.

Post transplant Kaposi's sarcoma among Nigerians: a report of two cases.

With the establishment of kidney transplant centres in Nigeria and increase in the number of kidney transplant recipients returning home for follow up after successful transplant abroad, an increasing number of patients with post transplant complications are likely to be seen. There is the need for physicians vested with the care of these patients to be aware of the post transplant complications so that early diagnosis and effective treatment can be instituted so as to save both the patient and the allograft. Two out of seventeen renal transplant recipients followed up in our unit had post renal transplant Kaposi's sarcoma. Both were successfully treated with withdrawal of cyclosporin, reduction of other immunosuppressives and introduction of low dose Mycophenolate Mofetil (MMF). One had a course of radiotherapy followed by weekly intravenous vincristine and the other only had vincristine with complete remission of the lesions in both patients. Post transplant Kaposi's sarcoma occurs in Nigerian transplant patients and this report highlights the need for increased awareness and high index of suspicion of post transplant Kaposi's sarcoma among kidney transplant recipients.

Bladder cancer in Kano--a histopathological review.

Malignant tumours of the bladder have been observed to be quite common in Kano but there has been no formal study. This four-year (1998-2001) retrospective review sought to document the pattern of these neoplasms. Vesical malignancies constituted 6.4% of all cancers in Kano with squamous (53%) and transitional (35%) carcinomas as the most common histological types. Males outnumbered females more than five times (M:F = 5.2.:1). Cancer of the bladder was most prevalent in the 5th and 6th decades with a mean age of 48.8 years. In general our findings are similar to bladder cancer in other schistosomal endemic regions of Africa.

Typhoid enteric perforation in north western Nigeria.

BACKGROUND: Typhoid perforation is the most important surgical complication of typhoid enteritis and is associated with high morbidity and mortality. AIMS AND OBJECTIVES: To determine the pattern and outcome of management of typhoid perforation in Aminu Kano University Teaching Hospital, Kano. METHOD: A retrospective Analysis of patients treated for typhoid perforation over a 6-year period. RESULTS: There were 47 patients: 35 males and 12 females, ratio 2.9 to 1. The patients were aged 4 years to 58 years (mean 18.9 years). Typhoid perforation occurred all the year round with a peak prevalence in September; Six (12.8%) patients perforated in the first week, 29 (61.7%) second week, and 12 (25.5%) third week, of illness. Single perforation was found in 91.5% of cases, and two to three perforations in 8.5%. Surgical treatment was by simple closure in 72.3%, wedge resection in 8.5%, ileal resection in 17.1% and right hemi-colectomy in 2.1%. Of the 41 survivors (87.2%), wound infection was the most common postoperative complication in 44.7% of cases. The mortality rate was 12.8% mostly due to overwhelming sepsis. CONCLUSION: Typhoid perforation requiring surgical intervention is still endemic in our subregion, and emphasis should be on preventive measures such as safe drinking water and appropriate sewage disposal, and typhoid vaccination.

Histopathological review of prostatic diseases in Kano, Nigeria.

Diseases of the prostate are common causes of morbidity in adult males and show wide geographical and ethnic variations in incidence and mortality worldwide. It is in the light of this that records of prostatic biopsies were reviewed in retrospect at the Aminu Kano Teaching Hospital, Kano and Murtala Mohammed Hospital Kano over a 4-year period in order to determine the histological pattern and age distribution of the various prostatic lesions. Three hundred and three prostatic lesions constituting 7.4% of all surgical biopsy specimens received were studied. Two hundred and thirty five (77.6%) of these were cases of BPH while prostatic cancer accounted for 22.4% of cases. The ratio of benign to malignant prostatic disease was 3:5:1. Chronic non-specific prostatitis, acute prostatitis, schistosomiasis and tuberculosis were present in 22.8%, 3.3%, 0.7% of the total number of cases respectively. The mean age of BPH patients was 63.7 years, and 88% of them had a glandulostromal histological pattern. Majority (64.2%) of the prostate cancers were well-differentiated adenocarcinoma and the mean age was 67.1 years. The findings confirm earlier observations that prostatic diseases are common causes of morbidity in our environment, and early diagnosis and treatment remain key measures in reducing mortality. The practice of 5-region biopsy is advocated to improve detection of clinical prostate cancer.

Effectiveness of pre-school- and school-based interventions to impact weight-related behaviours in African American children and youth: a literature review.

This review assessed the effectiveness of pre-school- and school-based obesity prevention and/or treatment interventions targeting healthy eating, physical activity or obesity in African American children and adolescents. Systematic searches were conducted for English-printed research articles published between January 1980 and March 2013. Retained articles included experimental studies conducted in the United States that targeted ≥ 80% African American/black children and adolescents and/or studies whose results were stratified by race/ethnicity, and that were conducted in pre-schools/head start or schools (excluding after-school programmes). Of the 12,270 articles identified, 17 met the inclusion criteria (pre-school, n=2; elementary school, n=7; middle and secondary schools, n=8). Thirteen studies found significant improvements in nutrition (pre-school, n=1; elementary, n=7; secondary, n=5) and three found significant improvements in physical activity (pre-school, n=1; elementary, n=2) variables of interest. Two studies (pre-school, n=1; secondary, n=1) reported significant reductions in obesity in African American children. The evidence available suggests school-based interventions are effective in promoting healthy nutrition behaviours in African American children. Conclusions overall and, particularly, about effects on physical activity and obesity are limited due to the small number of studies, differences in assessment approaches and a lack of follow-up assessments.

Screening for Middle East respiratory syndrome coronavirus infection in hospital patients and their healthcare worker and family contacts: a prospective descriptive study.

The Saudi Arabian Ministry of Health implemented a pro-active surveillance programme for Middle East respiratory syndrome (MERS) coronavirus (MERS-CoV). We report MERS-CoV data from 5065 Kingdom of Saudi Arabia individuals who were screened for MERS-CoV over a 12-month period. From 1 October 2012 to 30 September 2013, demographic and clinical data were prospectively collected from all laboratory forms received at the Saudi Arabian Virology reference laboratory. Data were analysed by referral type, age, gender, and MERS-CoV real-time PCR test results. Five thousand and 65 individuals were screened for MER-CoV: hospitalized patients with suspected MERS-CoV infection (n = 2908, 57.4%), healthcare worker (HCW) contacts (n = 1695; 33.5%), and family contacts of laboratory-confirmed MERS cases (n = 462; 9.1%). Eleven per cent of persons tested were children (<17 years of age). There were 108 cases (99 adults and nine children) of MERS-CoV infection detected during the 12-month period (108/5065, 2% case detection rate). Of 108 cases, 45 were females (six children and 39 adults) and 63 were males (three children and 60 adults). Of the 99 adults with MERS-CoV infection, 70 were hospitalized patients, 19 were HCW contacts, and ten were family contacts. There were no significant increases in MERS-CoV detection rates over the 12-month period: 2.6% (19/731) in July 2013, 1.7% (19/1100) in August 2013, and 1.69% (21/1238) in September 2013. Male patients had a significantly higher MERS-CoV infection rate (63/2318, 2.7%) than females (45/2747, 1.6%) (p 0.013). MERS-CoV rates remain at low levels, with no significant increase over time. Pro-active surveillance for MERS-CoV in newly diagnosed patients and their contacts will continue.

Transurethral prostatectomy in human immunodeficiency virus-infected patients, morbidity and surgical risks in a developing economy.

Human immunodeficiency virus (HIV) infection is increasing world-wide and highly active antiretroviral treatment (HAAT) is allowing afflicted individuals to live near normal life span and acquire surgical diseases of the aged as in the unaffected population. This pose occupational hazards to operating surgeons especially in tropical Africa where the seroprevalence is so high that seroconversion in the medical staff contaminated with the virus is estimated to be as much as 15 times (per annum) more than what obtains in developed. A 63-year old man was admitted to our Hospital with urethral catheter in situ and having failed medical therapy, he opted for transurethral prostatectomy (TURP) which was done without any post-operative complication. He was known to be afflicted with human immunodeficiency virus and on treatment for 3 years. He also had a large but reducible inguinoscrotal hernia for 4 years attributed to lower urinary tract obstruction. He had a Lichtenstein repair of right inguinoscrotal hernia which was complicated by small hematoma that was evacuated. The risk of transmission and surgical morbidity during transurethral prostatectomy could be minimized by adequate universal precaution, pre-testing of all consented patients and wise selection of patients that would benefit from such surgical therapy.

A recess intervention to promote moderate-to-vigorous physical activity.

BACKGROUND: Schools provide a prime environment for interventions that attempt to increase physical activity and prevent obesity. OBJECTIVE: This study examined the effect of a 30-min, structured recess using 22 games of known energy expenditure on moderate-to-vigorous physical activity when compared to free play implemented with third graders from two elementary schools over 9 weeks. METHODS: Moderate-to-vigorous physical activity and other cardiovascular risk factors were assessed pre- and post-intervention in 27 children. RESULTS: Moderate-to-vigorous physical activity during recess increased significantly in intervention school children from 6.9 ± 0.8 to 14.9 ± 0.9 min pre- and post-intervention, respectively (adjusted mean change 8.0 ± 1.1; P < 0.0001), with no differences by gender or body mass index (BMI). In-school, moderate-to-vigorous physical activity also increased significantly more for intervention compared to control children (adjusted mean change 14 ± 4 min vs. 3 ± 3 min; P = 0.014, respectively). CONCLUSION: There was no significant difference in BMI and cardiovascular risk factors. A structured recess is feasible to implement and can significantly increase moderate-to-vigorous physical activity.
