Disseminated tuberculosis: Clinical presentation, diagnosis, and outcomes in a tertiary-care hospital in Saudi Arabia.

Background: Tuberculosis (TB) is the primary infectious cause of mortality worldwide. Although TB incidence and prevalence are declining, the use of immunosuppressive drugs and the growing prevalence of immunocompromising conditions such as comorbidities, malignancies, and the use of immunosuppressive agents are risk factors for disseminated TB (DTB). This study aims to identify the relevant clinical, laboratory, radiological, and histopathological features of DTB, as well as to assess the typical anatomical distributions and treatment outcomes of patients diagnosed with the disease at King Abdulaziz Medical City (KAMC). Methods: A retrospective chart review was conducted, including all patients diagnosed with miliary or DTB at KAMC with retrievable medical files. Results: The study included 55 patients, of whom 35 (63.6%) were male and the median age was 64 years old. 35 (63.6%) of the infected patients were timely diagnosed and eventually cured from the illness. The most common comorbid conditions were diabetes, chronic kidney disease, and immunocompromising conditions, which were present in 37 (67.2%), 12 (21.8%), and 11 (20%) of the patients, respectively. The most common presenting symptoms were fever and cough, present in 31 (56.3%) and 26 (47.2%) of the patients, respectively, followed by weight loss in 25 (45.4%), night sweats in 15 (27.2%), and shortness of breath in 14 (25.4%). Approximately two-thirds of the patients had pulmonary miliary TB (MTB) (38; 69.1%), followed by TB lymphadenitis (21; 38.2%), central nervous system involvement (13; 23.6%), skeletal involvement (11; 20%), gastrointestinal involvement (5; 9.1%), pleural involvement (3; 5.5%), and urogenital TB (2; 3.6%). The mortality rate was 14 (25.5%) patients. Conclusion: MTB is challenging to diagnose due to nonspecific clinical, laboratory, and imaging findings. Clinicians dealing with patients who are at risk of developing DTB should be aware of the typical presentations and abnormal clinical findings. They should also have a low threshold to initiate specific investigations for the disease, as early diagnosis and effective treatment is critical in reducing morbidity and mortality rates.

Levothyroxine Timing during Ramadan: A Randomized Clinical Trial.

Introduction: Hypothyroidism requires lifelong thyroid hormone replacement with levothyroxine. For most hypothyroid patients fasting during Ramadan, compliance with the administration procedure is a challenge. This study aimed to determine the impact of different administration times of levothyroxine on thyroid-stimulating hormone (TSH) and free T4 (FT4) levels before and after the holy month of Ramadan. Materials and Methodology. Hypothyroid patients taking levothyroxine were randomized to 3 groups during Ramadan: group 1, 30 minutes before the iftar meal; group 2, 3-4 hours after the iftar meal, with no food taken for at least 1 hour after the meal; group 3, they were not given specific instructions for taking levothyroxine during Ramadan. Thyroid function tests were performed within 2 weeks before Ramadan and within 2 weeks after Ramadan. Pre- and post-Ramadan TSH and free T4 levels were compared. Mixed-effects analyzes were performed to identify factors associated with changes in TSH and FT4 levels. Results: Compliance was lower in patients taking levothyroxine 3-4 hours after iftar. In addition, the majority of patients who had not received a specific recommendation took levothyroxine 30 minutes before iftar. There was a statistically significant increase in TSH (P=0.006) and FT4 (P=0.044) levels after Ramadan. In multivariate analysis, the cause of hypothyroidism (Hashimoto's; postthyroidectomy; compared to postradioactive iodine) and levothyroxine dose significantly affected FT4 levels. In contrast, no variable was significantly associated with TSH level. The timing of levothyroxine intake during Ramadan did not significantly affect TSH or FT4 levels. Conclusion: TSH and FT4 significantly increased after Ramadan. However, the timing of levothyroxine intake per se had no influence on TSH or free T4 levels. Therefore, hypothyroid patients might take levothyroxine either 30 minutes or 3-4 hours after iftar with no meal for 1 hour, depending on preference.

Remote Ischaemic Conditioning in STEMI Patients in Sub-Saharan AFRICA: Rationale and Study Design for the RIC-AFRICA Trial.

PURPOSE: Despite evidence of myocardial infarct size reduction in animal studies, remote ischaemic conditioning (RIC) failed to improve clinical outcomes in the large CONDI-2/ERIC-PPCI trial. Potential reasons include that the predominantly low-risk study participants all received timely optimal reperfusion therapy by primary percutaneous coronary intervention (PPCI). Whether RIC can improve clinical outcomes in higher-risk STEMI patients in environments with poor access to early reperfusion or PPCI will be investigated in the RIC-AFRICA trial. METHODS: The RIC-AFRICA study is a sub-Saharan African multi-centre, randomized, double-blind, sham-controlled clinical trial designed to test the impact of RIC on the composite endpoint of 30-day mortality and heart failure in 1200 adult STEMI patients without access to PPCI. Randomized participants will be stratified by whether or not they receive thrombolytic therapy within 12 h or arrive outside the thrombolytic window (12-24 h). Participants will receive either RIC (four 5-min cycles of inflation [20 mmHg above systolic blood pressure] and deflation of an automated blood pressure cuff placed on the upper arm) or sham control (similar protocol but with low-pressure inflation of 20 mmHg and deflation) within 1 h of thrombolysis and applied daily for the next 2 days. STEMI patients arriving greater than 24 h after chest pain but within 72 h will be recruited to participate in a concurrently running independent observational arm. CONCLUSION: The RIC-AFRICA trial will determine whether RIC can reduce rates of death and heart failure in higher-risk sub-optimally reperfused STEMI patients, thereby providing a low-cost, non-invasive therapy for improving health outcomes.

The Prevalence of Active Epilepsy in the Kingdom of Saudi Arabia: A Cross-Sectional Study.

INTRODUCTION: The global prevalence of active epilepsy is around 6.38/1,000 persons. In the Arabian region, the median prevalence of active epilepsy is 4.4/1,000 persons. In the Kingdom of Saudi Arabia (KSA), the last prevalence study for active epilepsy cases was conducted in 2001 and showed an estimate of 6.5/1,000 persons. OBJECTIVES: The aim of the study was to investigate the prevalence of active epilepsy and etiological factors among Saudi individuals of all ages resident in the Riyadh area, the central province, and the capital of KSA. METHOD: This is a door-to-door cross-sectional epidemiological study that was conducted between 2012 and 2016. Patients were initially screened at their homes using a questionnaire, and then suspected individuals were interviewed in the clinic by neurologists and epileptologists. Data related to age, age at seizure onset, gender, probable etiology, treatment, family history, duration of epilepsy, and seizure control, as well as images for electroencephalogram and magnetic resonant imaging, were collected and analyzed. RESULTS: Among the 13,873 participants, active epilepsy was evidenced in 55 patients (3.96; 95% CI: [2.99-5.16]/1,000 persons). No significant variation in the prevalence rate was detected between male and female patients (3.99 vs. 3.94/1,000 persons). The age-specific prevalence was the highest among the infants (1-12 months) (14.78/1,000 persons). Of the various seizure types, complex partial seizures were the most common (33%), followed by generalized seizures (29.1%). Concerning etiology, epilepsies with idiopathic and cryptogenic etiologies were the most common in 18 (36.3%) cases. Structural, vascular, and focal abnormalities were the most commonly diagnosed abnormalities (18.2%, 14.5%, and 39.2%, respectively). CONCLUSION: The prevalence of active epilepsy in KSA has dramatically decreased during the last decades to a rate lower than those reported in most developing countries.

Prevalence and factors associated with dyslipidemia among adolescents in Saudi Arabia.

Dyslipidemia is a major risk factor for atherosclerosis. Screening for dyslipidemia at an early age is essential to prevent and control its consequences. This study aimed to determine prevalence of dyslipidemia and its correlates among adolescents in Saudi Arabia. Data of 5854 adolescents aged 10-19 years from all 13 regions of Saudi Arabia were obtained from the Jeeluna study; a national cross-sectional, multistage stratified cluster sample survey. Dyslipidemia was defined based on the National Heart Lung and Blood Institute and National Cholesterol Education Program guidelines for adolescents. We found that a quarter of Saudi adolescents have dyslipidemia (males: 33.3%, females: 17.9%). Significant variation was observed by region (p < 0.001). Prevalence of abnormal Total Cholesterol was 6.7%, LDL-C 7.1%, HDL-C 12.8%, Non-HDL-C 8.3%, and Triglycerides 9.6%. Factors independently associated with dyslipidemia were male gender (OR = 2.19, 95% CI 1.78-2.70, p < 0.001), BMI (underweight OR = 0.80, 95% CI 0.69-0.94, overweight OR = 1.76, 95% CI 1.50-2.06, obese OR = 2.80, 95% CI 2.34-3.34, p < 0.001, vs. normal) and serum ferritin (high OR = 7.02, 95% CI 1.49-34.79, low OR = 0.82, 95% CI 0.67-1.01, p = 0.04 vs. normal) and ≥ 1 daily intake of carbonated beverage (OR = 1.10, 95% CI 1.00-1.20, p = 0.03 vs. no or not daily intake). Public health interventions for improving lipid profile of adolescents are urgently needed.

Timing of Puberty and Late Pubertal Height in Saudi Schoolboys: Riyadh Puberty Study II.

Objective: Puberty has a significant contribution to the final height. Therefore, it is crucial to understand the normal variations in the onset and tempo of puberty in a specific population. In this study, we aimed to provide normative data on the timing of puberty and late pubertal height (LPH) in Saudi schoolboys in Riyadh. Methods: This is a cross-sectional field study (2011-2013) including Saudi schoolboys (grades 1-12; aged 6 to 19 years). Schools were chosen to represent the population from urban and rural areas in the Riyadh region. Pubertal maturity staging for gonads was assessed by measuring testicular size using a Prader orchidometer and assessing the Tanner staging of pubic hair. The marginal mean age was calculated using regression analysis. Results: We recruited 1086 schoolboys. The estimated mean age of pubertal onset at G2 was 11.8 (95% CI 11.60-12.0) years, for gonadal development at G3 was 13.2 (95% CI 12.9-13.5), G4 = 15.0 (95% CI 14.7-15.2), and G5 = 16.1 (95% CI 15.9-16.3) years, and for pubic hair stage 2 (PH2) was 12.6 (95% CI 12.4-12.9) years. The estimated time from G2/PH2 to G5/PH5 was 4.3 and 3.9 years, respectively. At the onset of puberty, the mean height was 144.7 cm and it reached 167.8 cm at G5 with a pubertal height gain of 23.1 cm. Conclusion: Our data present the norms of the timing of puberty and LPH in Saudi schoolboys. Saudi adolescent males are shorter than some European and American comparatives mainly due to shortness during childhood. However, they could have shorter LPH than Turkish, Greek, Thai, and Japanese due to a less pubertal height gain.

Factors associated with mortality and morbidity among pediatrics with burn injuries in Riyadh, Saudi Arabia.

OBJECTIVES: To describe characteristics, mechanism, and factors associated with morbidity and mortality of pediatrics with burn injuries. METHODS: This cross-sectional retrospective study examined all pediatrics with burn injuries carried out at King Abdulaziz Medical City, Riyadh, Saudi Arabia, from 2015-2020. Collected data included demographics, mechanism of burn, total body surface area (TBSA) burned, body region burned, incidence of infection, renal failure, scars, and respiratory events. RESULTS: The study included 370 patients. Approximately 47.0% were aged ≤2 years, and 61.0% were males. The most common burn mechanism was scald burn (54%), 59.2% had a TBSA of 0-10%, and 60.3% had regional burns on the upper limbs. During follow-up, 5 patients died (incidence rate [IR]=1.60/100 patient/years [PYs]). Morbidity events included blood/sepsis infection (IR=2.87/100 PYs), urine infection (IR=8.30/100 PYs), wound infection (IR=21.72/100 PYs), renal failure (IR=0.96/100 PYs), and respiratory infections (IR=1.60/100 PYs). In a multivariate Cox regression analysis, factors independently associated with combined hazard of morbidity and mortality were female gender (hazard ratio [HR]=1.64, 95% confidence intervel [CI]: [1.01-2.67], p=0.047), TBSA (HR=3.20, 95% CI: [1.828-5.585], p<0.0001), and length of hospital stay (HR=3.14, 95% CI: [1.91-5.17], p=0.000). CONCLUSION: This study identifies certain characteristics suggestive of poor outcomes of pediatric burn injuries that are relevant to clinical management and prevention programs. Larger multicenter studies are required to fully characterize pediatric patients with burn injuries and to identify factors that adversely affect their prognosis.

Patterns of adverse drug reactions (ADRs) in Saudi Arabia.

BACKGROUND: Pharmacovigilance enhances post-market drug safety. However, analytical reports of a pattern of adverse drug reactions (ADRs) experienced by patients in Saudi Arabia are demanded. OBJECTIVE: To describe patterns of ADRs submitted to the Saudi Central National Pharmacovigilance and Drug Safety Center (NPC), Saudi Food and Drug Administration (SFDA), from its inception in 2015 until the end of 2017 to understand the pattern of ADR reporting in Saudi Arabia. METHODS: In this retrospective study, data from cases reported to the NPC were used to determine ADRs and identify the most common associated drug classes based on anatomical therapeutic chemical (ATC) classification system. RESULT: A total of 17,730 ADR cases were reported during study period. An annual increase in ADRs was clearly evident. Approximately 54% of the total ADRs reported were serious. Most commonly reported ATC drug classes were anti-infective agents for systemic use (22.27%), antineoplastic and immunomodulating agents (21.49%), alimentary tract and metabolism (15.48 %), cardiovascular system (11.11%) and nervous system (10.23%). Vancomycin (2.7%), ceftiraxone (1.8%), fingolimod (1.4%) and paracetamol (1.4%) were the most common drugs associated with serious ADRs. CONCLUSION: This study provide valuable insights in hypothesis generation for future studies on drug-event interactions and amplification studies. The NPC educational programs and awareness campaigns to promote systematic reporting of ADRs among healthcare professionals and general public should be continued.

Parents' perceptions of quality of life of their children and adolescents with type 1 diabetes during Ramadan fasting in Riyadh.

This study aimed to assess parents' perceptions of the quality of life (QoL) of their children with type 1 diabetes (T1D) during Ramadan fasting (RF). In this cross-sectional study, an Arabic-translated version of the standard diabetes-specific QoL questionnaire (PedsQL™ version 3.0) was used to compare perceptions of QoL during Ramadan month (Rm) versus non-Rm (NRm) of parents of children/adolescents with T1D from two tertiary hospitals in Riyadh. We used regression analysis to compare proxies (parents' reports) of their perceptions on their children/adolescents' QoL during Rm compared to NRm. A sample of 61 proxies (parents') of two age groups T1D offspring: 8-12 years (41%) and 13-18 years (59%) who reported their perceptions of their children/adolescents QoL during Rm were matched by children/adolescents' age and gender of 61 proxies in NRm. QoL scores of all domains were significantly lower in Rm compared to NRm; p < 0.0001, however, worries domain showed no statistical differences p = 0.052 in a regression analysis. The total aggregate median (IQR) in Rm was 850 (612-1,062) compared to 1,750 (1,475-2,062) in NRm, p < 0.001. The highest differences in NRm and Rm median scores were observed in communications (OR = 3.64; 95% CI 2.7-5.57) and treatment adherence (OR = 3.09; 95% CI 2.48-3.84) domains especially in the age of 13-18 years. Parents of adolescent boys, who are usually risk-takers and more exposed to outdoor activities, perceived lower QoL for them. Parents of adolescents with T1D perceived a lower QoL for their children during RF, especially in the treatment adherence and communication domains.

Quality of Life and Glycemic Control in Saudi Children with Type 1 Diabetes at Different Developmental Age Groups.

BACKGROUND: Children with type 1 diabetes (T1D) at different stages of development have age-specific needs, which can influence their perception of quality of life (QoL). In our study, we aimed to emphasize these age-specific needs and assess the perception of QoL in Saudi children with T1D, as well as their parents correlating QoL scores with children's glycemic control. METHODS: This is a cross-sectional study in which children with T1D and their parents from 2 tertiary institutes in Saudi Arabia have answered a standard diabetes-specific QoL questionnaire (PedsQL™ 3.0 diabetes module, translated in Arabic). We also reported glycated hemoglobin (HbA1c) results for these children within a month of completing the questionnaire. The QoL total aggregate and domain scores for self (children) and proxy (parents') reports were compared and correlated with children's HbA1c. RESULTS: A sample was 288 self and proxy reports from 144 children with T1D of 3 age groups: 5 to 7 years (7%), 8 to 12 years (49%), and 13 to 18 years (44%), and their parents. QoL differed significantly between self and proxy reports in the total aggregate and domain scores (P-values range from .02 to <.001). The impact on QoL was significantly higher in female patients (P = .043). Insulin pump users had better HbA1c (P = .007), and HbA1c level was worse in those who intended to fast at Ramadan (P = .005). CONCLUSION: Children with T1D at different developmental age groups perceive QoL differently than their parents. Adjusting management as per age-specific challenges could potentially improve these children's QoL and glycemic control.

Rationale and design of the African Cardiomyopathy and Myocarditis Registry Program: The IMHOTEP study.

BACKGROUND: Heart failure (HF), the dominant form of cardiovascular disease in Africans, is mainly due to hypertension, rheumatic heart disease and cardiomyopathy. Cardiomyopathies pose a great challenge because of poor prognosis and high prevalence in low- and middle-income countries (LMICs). Little is known about the etiology and outcome of cardiomyopathy in Africa. Specifically, the role of myocarditis and the genetic causes of cardiomyopathy are largely unidentified in Africans. METHOD: The African Cardiomyopathy and Myocarditis Registry Program (the IMHOTEP study) is a pan-African multi-centre, hospital-based cohort study, designed with the primary aim of describing the clinical characteristics, genetic causes, prevalence, management and outcome of cardiomyopathy and myocarditis in children and adults. The secondary aim is to identify barriers to the implementation of evidence-based care and provide a platform for trials and other intervention studies to reduce morbidity and mortality in cardiomyopathy. The registry consists of a prospective cohort of newly diagnosed (i.e., incident) cases and a retrospective (i.e., prevalent) cohort of existing cases from participating centres. Patients with cardiomyopathy and myocarditis will be subjected to a standardized 3-stage diagnostic process. To date, 750 patients have been recruited into the multi-centre pilot phase of the study. CONCLUSION: The IMHOTEP study will provide comprehensive and novel data on clinical features, genetic causes, prevalence and outcome of African children and adults with all forms of cardiomyopathy and myocarditis in Africa. Based on these findings, appropriate strategies for management and prevention of the cardiomyopathies in LMICs are likely to emerge.

Risk factors, antimicrobial susceptibility pattern and patient outcomes of Pseudomonas aeruginosa infection: A matched case-control study.

BACKGROUND: Pseudomonas aeruginosa is a leading nosocomial Gram-negative bacteria associated with prolonged hospitalization, and increased morbidity and mortality. Limited data exist regarding P. aeruginosa infection and outcome in patients managed in intensive care units (ICUs) in the Gulf countries. We aimed to determine the risk factors, antimicrobial susceptibility pattern and patient outcomes of P. aeruginosa infection in ICU. METHODS: In this matched case-control study, all P. aeruginosa infections that occurred >48 h after hospital admission between January 31st 2016 and December 31st 2018 at ICUs affiliated with King Abdulaziz Medical City, Riyadh were included. P. aeruginosa was identified using MALDI-TOF (Vitek-MS) by biomérieux, and the antimicrobial susceptibility testing was performed using an automated biomérieux VITEK®ï¸ 2 Antimicrobial Susceptibility card. RESULTS: The study included 90 cases and 90 controls. Compared with controls, cases had significantly higher mean ICU stay and higher proportions with previous history of antimicrobial therapy, coronary artery disease, malignancy, hemodialysis, previous surgery, use of central line, urethral catheterization, nasogastric tube, and tracheostomy. In a multivariate conditional logistic regression analysis, factors independently associated with P. aeruginosa infection were ICU duration [Odds Ratio (OR) 9.05, 95%CI 2.53-32.27, p = .001], previous surgery (OR = 7.33, 95%CI 1.66-32.36, p = .009), tracheostomy (OR = 11.13, 95%CI 1.05-118.59, p = .046), urethral catheterization (OR = 7.38, 95%CI 1.21-45.11, p = .030) and use of aminoglycosides (OR = 10.59, 95%CI 1.14-98.13, p = .038). Approximately 41% of P. aeruginosa isolates were resistant to imipenem, while 36.7% were multidrug-resistant. Mortality was similar in both groups: 54(60%) cases and 51(56.7%) controls; p = .650. CONCLUSIONS: The study identifies several potentially modifiable factors associated with P. aeruginosa infection in ICUs. Identification of these factors could facilitate case identification and enhance control measures.

Vancomycin in ICU Patients with Gram-Positive Infections: Initial Trough Levels and Mortality.

BACKGROUND: Vancomycin is one of the most common therapeutic agents for treating gram-positive infections, particularly in critically ill patients. The aim of this study was to identify factors associated with initial therapeutic vancomycin trough levels and mortality in a tertiary-care intensive care unit (ICU). METHODS: This retrospective study evaluated 301 adult ICU patients admitted to King Abdulaziz Medical City in Riyadh between October 1, 2017 and December 31, 2018 with confirmed gram-positive infections and received intravenous vancomycin. Vancomycin trough levels of 15-20 mg/L for severe infections and 10-15 mg/L for less severe infections were considered therapeutic. RESULTS: The patients were relatively older with a mean age of 60 (SD ±20) years. Initial vancomycin trough levels were therapeutic in 168 (55.8%). Factors associated with initial therapeutic vancomycin trough levels were female gender (adjusted odds ratio [aOR]=2.575), older age (aOR=1.024), receiving a loading dose (aOR=2.445), having bacteremia (aOR=2.061), and high platelet count (aOR=1.003). On the other hand, the increase of estimated glomerular filtration rate (eGFR) (aOR=0.993) and albumin levels (aOR=0.944) were associated with lower odds of initial therapeutic vancomycin trough levels. Factors associated with higher mortality were female gender (adjusted hazard ratio [aHR]=2.630), increased body weight (aHR=1.021), cancer (aHR=3.451), and high APACHE II score (aHR=1.068). CONCLUSION: The study identified several factors associated with achieving initial therapeutic vancomycin trough levels (i.e. older age, female gender, receiving a loading dose, bacteremia, high platelets count, low eGFR and albumin level). These factors should be considered in the dosing of vancomycin in critically ill patients with gram-positive infections.

Prevalence and Risk Factors for Diabetic Peripheral Neuropathy Among Saudi Hospitalized Diabetic Patients: A Nested Case-Control Study.

OBJECTIVE: To determine the prevalence and the risk factors of diabetic peripheral neuropathy (DPN) in hospitalized adult Saudi diabetics. METHODS: This is a retrospective, nested case-control study conducted at King Abdulaziz Medical City (KAMC) in Riyadh, Saudi Arabia. All diabetic patients admitted to the hospital between the January 1, and December 31, 2018 were considered for inclusion in the study. Patients with DPN were identified and three controls per case were randomly selected from the remaining diabetic patients without peripheral neuropathy (PN). RESULTS: A total of 2,096 adult diabetic patients were identified during the study period. Of these, 73 patients (3.5%) were confirmed to be suffering from DPN and 219 were included as controls. When comparing diabetic with the control cases, DPN cases were significantly older (p=0.002), had a significantly higher proportion of type 2 diabetes (p=0.023), chronic kidney disease (p<0.0001), cerebral vascular stroke (p=0.027), hypertension (p=0.005), dyslipidemia (p=0.002), peripheral vascular disease (p<0.0001), osteoarthritis (p=0.034), diabetic ketoacidosis (p=0.003), foot ulcers (p=0.006), gangrene (p=0.001), lower limb ischemia (p=0.001), increased duration with diabetic disease (p=0.031), increased BMI (p=0.003), higher serum creatinine (p<0.001) and lower serum albumin levels (p=0.035). In the multivariate logistic regression, only older age {odds ratio (OR) 1.02, 95% CI 1.01-1.04, p=0.031}, chronic kidney disease (OR 2.39, 95% CI 1.23-4.64, p=0.010) and peripheral vascular disease (OR 3.14, 95% CI 1.39-7.13, p=0.006) were independently associated with DPN. CONCLUSION: This study identified several risk factors that contributed to the development of DPN in Saudis. These must be considered in strategies and campaigns aimed at risk reduction of cardiovascular and chronic diseases, and consequently progression of DPN.

Higher serum alkaline phosphatase activity in infants born to vitamin D-deficient mothers.

Our research shows that the newborns of vitamin D-deficient mothers have higher serum alkaline phosphatase (ALP) activity compared with those of vitamin D-non-deficient mothers, which is likely related to increased bone turnover rather than just being a marker for bone formation. This has a potential negative impact on fetal bone development and subsequent skeletal growth. PURPOSE/INTRODUCTION: Low maternal serum 25-hydroxy vitamin D (25(OH)D) level during pregnancy contributes to vitamin D deficiency in infants at birth, which is associated with multiple potential adverse effects on fetal skeletal mineralization and growth. We studied the relationship between maternal 25(OH)D level and newborn serum alkaline phosphatase activity (ALP) at term. METHODS: In this prospective cross-sectional hospital-based study, venous blood samples of healthy pregnant mothers were drawn to measure 25(OH)D levels within 6 h of delivery. Cord blood samples were examined for calcium, phosphorus levels, and ALP activity immediately after birth. In addition, we also recorded the newborns' anthropometric measurements. RESULTS: Seventy-two percent (n = 108/150) of mothers in our study were vitamin D-deficient (serum 25(OH)2D < 25 nmol/l). In a multivariate logistic regression model, young maternal age (odds ratio (OR) = 0.94, 95% CI 0.88-0.99, p = 0.04) and increased weight (OR = 1.03, 95% CI 1.01-1.07, p = 0.02) as well as decreased milk intake (OR = 0.31, 95% CI 0.13-0.74, p = 0.009) were all significantly associated with maternal vitamin D deficiency. ALP activity was significantly higher in newborns of vitamin D-deficient compared with vitamin D-non-deficient mothers (median = 176 (IQR = 139-221) and 156 (IQR = 132-182), respectively, p = 0.04). A significant inverse correlation (Pearson's coefficient = - 0.18, p = 0.03) was observed between maternal 25(OH)D levels and babies' ALP activities. This association persisted in a multivariate logistic regression model (OR = 3.46, 95% CI 1.18-10.18, p = 0.024). CONCLUSIONS: Our findings indicate that newborns of vitamin D-deficient mothers have higher serum ALP activity than those of non-deficient mothers, which might be related to increased bone turnover rather than just being a marker for bone formation. This could have a potential negative impact on fetal bone development and subsequent skeletal growth.

An assessment for diagnostic and therapeutic modalities for management of pediatric Iron defficiency Anemia in Saudi Arabia: a crossectional study.

INTRODUCTION: Iron deficiency anemia (IDA) is a global public health issue that affect more than 2 billion individuals worldwide. However evidence for optimal management of IDA is lacking. METHODS: To assess the diagnostic criteria and therapeutic modalities for pediatric IDA employed by physicians in a major public healthcare facility in Riyadh, a validated questionnaire including demographic data and patient case-scenarios related to diagnosis and treatment of IDA was employed. Robust regression analysis was used to identify factors associated with overall score of participants. RESULTS: Of the 166 physicians surveyed 147(88.6%) were included in the study. Wide variability was observed in IDA diagnosis and therapy practises. For nutritional IDA, only 15.6% recommended no other laboratory tests in addition to CBC. The majority preferred treatment with ferrous sulfate (77.6%) divided into two doses (57.1%), but the total daily elemental iron doses varied widely from 2 to 6 mg/kg. For intravenous iron, 42.9% recommended iron dextran, 32.7% iron sucrose, and 13.4% would continue oral iron. Of all assessed factors, median score was significantly highest in pediatric hematologists compared with pediatricians, family medicine specialists and GPs; p = 0.007, and those work in tertiary care compared with those in primary care; p = 0.043. However, in multivariate robust regression analysis, overall score was only significantly associated with professional qualification [pediatric hematologist ß = 13.71,95%CI 2.48-24.95, p = 0.017; pediatrician ß = 1.77,95%C (- 6.05-9.59, p = 0.66; family medicine ß = 2.66,95%CI-4.30-9.58, p = 0.45 compared with general practitioner]. CONCLUSION: Wide variations exist among physicians in diagnosis and treatment of pediatric IDA. Intervention programs and national guidelines are urgently needed.

Comparison of Dual Therapies for Lowering Blood Pressure in Black Africans.

BACKGROUND: The prevalence of hypertension among black African patients is high, and these patients usually need two or more medications for blood-pressure control. However, the most effective two-drug combination that is currently available for blood-pressure control in these patients has not been established. METHODS: In this randomized, single-blind, three-group trial conducted in six countries in sub-Saharan Africa, we randomly assigned 728 black patients with uncontrolled hypertension (≥140/90 mm Hg while the patient was not being treated or was taking only one antihypertensive drug) to receive a daily regimen of 5 mg of amlodipine plus 12.5 mg of hydrochlorothiazide, 5 mg of amlodipine plus 4 mg of perindopril, or 4 mg of perindopril plus 12.5 mg of hydrochlorothiazide for 2 months. Doses were then doubled (10 and 25 mg, 10 and 8 mg, and 8 and 25 mg, respectively) for an additional 4 months. The primary end point was the change in the 24-hour ambulatory systolic blood pressure between baseline and 6 months. RESULTS: The mean age of the patients was 51 years, and 63% were women. Among the 621 patients who underwent 24-hour blood-pressure monitoring at baseline and at 6 months, those receiving amlodipine plus hydrochlorothiazide and those receiving amlodipine plus perindopril had a lower 24-hour ambulatory systolic blood pressure than those receiving perindopril plus hydrochlorothiazide (between-group difference in the change from baseline, -3.14 mm Hg; 95% confidence interval [CI], -5.90 to -0.38; P = 0.03; and -3.00 mm Hg; 95% CI, -5.8 to -0.20; P = 0.04, respectively). The difference between the group receiving amlodipine plus hydrochlorothiazide and the group receiving amlodipine plus perindopril was -0.14 mm Hg (95% CI, -2.90 to 2.61; P=0.92). Similar differential effects on office and ambulatory diastolic blood pressures, along with blood-pressure control and response rates, were apparent among the three groups. CONCLUSIONS: These findings suggest that in black patients in sub-Saharan Africa, amlodipine plus either hydrochlorothiazide or perindopril was more effective than perindopril plus hydrochlorothiazide at lowering blood pressure at 6 months.

Quality of life among home healthcare patients in Saudi Arabia: household-based survey.

BACKGROUND: The need for home healthcare programs is an increasingly becoming important common component of healthcare worldwide, as an alternative to hospitalization, owing to the growing elderly population, chronic and acute diseases that need continuous monitoring and care. The overall aim of this study was to describe and assess the quality of life (QOL) and associated determinants among patients enrolled in the Home Health Care (HHC) program affiliated with the Ministry of National Guard Health Affairs in Riyadh, Saudi Arabia. METHODS: This cross-sectional study was conducted among patients enrolled at the HHC program. The World Health Organization QOL questionnaire (WHOQOL-BREF) was used to collect data about the different domains of patients' QOL. Logistic regression models were fitted to determine factors associated with QOL low score. RESULTS: The study included 253 patients. Mean age was 67.05 (± 20.0). The overall QOL for HHC patients was significantly affected by both socio-demographic and morbid characteristics. In the final Multivariate logistic regression models, marital status, and having psychological problems, stroke and number illness were independently associated with the overall QOL of HHC patients (p = .022, p = .002, p = .031, .057 respectively). The physical health domain score was significantly associated with education level, having psychological problems and stroke (p = .028, p = .002, p = .007 retrospectively) whereas the psychological domain score was significantly associated with age (p = < 0.001) and three types of chronic diseases: pulmonary (p = .002), psychological problems (p = < 0.001). The social domain score was significantly associated only with the marital status (p = .026). The environmental domain was significantly associated with the education level and having stroke (p = .017 vs .027). CONCLUSIONS: The overall QOL and its domains are significantly associated with several different factors. Many of these factors can be monitored and enhanced by improving quality of HHC services, thus improving the QOL of patients.

Does physician distraction lead to diagnostic and management errors? An exploratory study in the primary care setting.

OBJECTIVES: There is an increasing concern about diagnostic errors and their impact on patient safety. Physicians' diagnostic ability is significantly undermined by certain distractions that can carry potential negative consequences such as diagnostic and management errors. This study aimed to examine the effects of distracting factors for physicians during consultation and their consequent effects on diagnostic accuracy and disease or condition management. METHODS: Family medicine residents at a major training hospital in KSA were randomly assigned to two groups of simulated patients: one group with patients with distracting features and another group with patients without distracting features (the control group). Both groups encountered six simulated patients with different clinical conditions or diseases. The consultation time, accuracy of diagnosis, appropriateness of management, number of outlines of treatment, and simulated patient satisfaction were measured for both groups. RESULTS: A total of 70 simulated physician-patient encounters were conducted with 35 residents. Consultation time was significantly longer for encounters with patients with distracting features, which had a mean time of 7.43 min, compared with encounters with non-distracting patients, which had a mean time of 4.4 min (p value < 0.0001). There were no significant statistical differences in accuracy of diagnosis, appropriateness of management, or patient satisfaction between the two groups. However, residents recommended a higher number of outlines of treatment for patients with distracting features (2.96 for distracting patients versus 2.46 for non-distracting patients; p < 0.011). CONCLUSION: Distracting factors are associated with prolonged consultation time among physicians. Although this study did not demonstrate any effects of distracting factors on accuracy of diagnosis or disease management, these factors are still concerning, especially in complex clinical situations and situations where there is lack of reflective practice. The effects of distracting factors should be minimized to ensure patient safety.

Risk of diagnostic errors when dealing with aggressive patients: Experimental study.

Medical errors are still common despite advances in technology and policies to insure patients' safety. They can be traceable as in medications or surgical errors, but may not be so in diagnostic errors that are patient, physician, or system related. This study aimed to explore whether aggressive behavior of some patients might affect physicians' clinical reasoning and decision-making. The study was conducted in a format of observation skills clinical examinations (OSCEs). It included simulating patients (SPs) and family physicians in residency training in a clinical setup. The experiment included two arms of dealing with case scenarios with "Neutral" and "Aggressive" behaviors. Explanatory variables assessed were duration of consultation, correct diagnosis, and plan of appropriate management as well as patients' satisfaction. Participants were 14 trained SPs who played the roles of aggressive and nonaggressive patients when they encountered 35 residents (18 were males) in family physicians [year 2 (R2), year 3 (R3) and year 4 (R4)]; in a total of seventy patient/doctor encounters. Compared with nonaggressive patients, aggressive patients had statistically significantly prolonged OSCE duration [mean (standard deviation) = 6.89 (1.35) and 6.11 (157) min, respectively; P = 0.031] and more patient consultation satisfaction (P <0.0001). However, no statistically significant differences were found in diagnostic accuracy (P = 0.626) and management (P = 0.621). In a stratified analysis, junior doctors had longer duration of consultation and seemed to perform better in management (higher patient satisfaction and better management outline) than their senior counterparts. Patients' aggressive behavior led to longer duration of medical consultation. Poor management plan, albeit correct diagnosis, in senior doctors may be due to disruptive clinical reasoning in disturbed stressful situation. Coping strategies should be emphasized in medical education to ensure effective clinical reasoning in patient/doctor encounters.
