The prevalence of sedentary behavior among university students in Saudi Arabia.

BACKGROUND: A considerable body of research has demonstrated that reducing sitting time benefits health. Therefore, the current study aimed to explore the prevalence of sedentary behavior (SB) and its patterns. METHODS: A total of 6975 university students (49.1% female) were chosen randomly to participate in a face-to-face interview. The original English version of the sedentary behavior questionnaire (SBQ) was previously translated into Arabic. Then, the validated Arabic version of the SBQ was used to assess SB. The Arabic SBQ included 9 types of SB (watching television, playing computer/video games, sitting while listening to music, sitting and talking on the phone, doing paperwork or office work, sitting and reading, playing a musical instrument, doing arts and crafts, and sitting and driving/riding in a car, bus or train) on weekdays and weekends. RESULTS: SBQ indicated that the total time of SB was considerably high (478.75 ± 256.60 and 535.86 ± 316.53 (min/day) during weekdays and weekends, respectively). On average, participants spent the most time during the day doing office/paperwork (item number 4) during weekdays (112.47 ± 111.11 min/day) and weekends (122.05 ± 113.49 min/day), followed by sitting time in transportation (item number 9) during weekdays (78.95 ± 83.25 min/day) and weekends (92.84 ± 100.19 min/day). The average total sitting time of the SBQ was 495.09 ± 247.38 (min/day) and 58.4% of the participants reported a high amount of sitting time (≥ 7 hours/day). Independent t-test showed significant differences (P ≤ 0.05) between males and females in all types of SB except with doing office/paperwork (item number 4). The results also showed that male students have a longer daily sitting time (521.73 ± 236.53 min/day) than females (467.38 ± 255.28 min/day). Finally, 64.1% of the males reported a high amount of sitting time (≥ 7 hours/day) compared to females (52.3%). CONCLUSION: In conclusion, the total mean length of SB in minutes per day for male and female university students was considerably high. About 58% of the population appeared to spend ≥7 h/day sedentary. Male university students are likelier to sit longer than female students. Our findings also indicated that SB and physical activity interventions are needed to raise awareness of the importance of adopting an active lifestyle and reducing sitting time.

Anthropometrics and Plasma Atherogenic Index in Saudi Women Madinah KSA.

Objective: to determine the lipid profile levels and association with anthropometric measurements and atherogenic index of plasma values in females from Taibah University. Methods: A cross-sectional study was conducted from January 2019 to January 2020 at the female section of Taibah University, located in Madinah, Saudi Arabia. The study sample consisted of 240 females ranging from 19 to 50 years. Measurements related to anthropometry such as height, weight, waist, and hip circumference, were calculated. Body Mass Index, Lipid profiles, and Atherogenic Index of Plasma were also measured. Results: Almost 73.4% of the participants were obese and overweight, with a mean BMI of 28.79±5.7 kg/m2. Overweight and obese women were observed to have high total cholesterol and triglyceride levels (P≤0.05). Out of 244 participants, 120 (49.2%) and 44 (18%) were at intermediate and high risk of cardiovascular disease (CVD), respectively, as determined by the atherogenic index of plasma AIP. Intermediate and high-risk CVD groups had higher lipid profile levels and high waist-to-hip ratio compared to those in females at low risk (P≤0.05). AIP was positively and significantly associated with total cholesterol and triglyceride but negatively correlated with HDL concentration. Furthermore, the BMI had significantly positive correlation with triglyceride and waist to hip ratio (P≤0.05). Conclusion: The majority of the participants were overweight and obese, with high levels of triglycerides and total cholesterol and high waist to hip ratio, placing them at intermediate or high risk of CVD based on AIP values. Additional CVD risk screenings, targeted specifically at overweight and obese women, are needed.

Validity and reliability of the Arabic sedentary behavior questionnaire among university students aged between 18-30 years old.

PURPOSE: The study aimed to test the validity and reliability of the Arabic version of the sedentary behavior questionnaire (SBQ). METHODS: A total of 624 university students (273 males; 351 females, mean age = 20.8 years) were recruited from Taibah University, Madinah, Saudi Arabia. For criterion and constructive validity (n = 352), the Arabic SBQ was compared with total sitting time from the International Physical Activity Questionnaire-short form (IPAQ-SF) and the International Physical Activity Questionnaire-long form (IPAQ-LF). For concurrent validity, the English and Arabic SBQ versions were given concurrently to bilingual university students (n = 122) once. For test-retest reliability, the Arabic SBQ was given twice to participants (n = 150) at a one-week interval. RESULTS: Sitting time of IPAQ-SF (7th question: sitting time on weekdays) and IPAQ-LF (21st question: sitting time on weekdays and 22nd question: sitting time on weekends) correlated significantly with total sitting time/week of the Arabic SBQ (r = 0.29, p = 0.003; r = 0.14, p = 0.02, respectively). Motorized transportation measured with the IPAQ-LF correlated significantly with time spent driving in a car, bus, or train from the Arabic SBQ on weekdays and weekends (r = 0.53, p < 0.001; r = 0.44 p < 0.001, respectively). The total sitting time of the Arabic SBQ was inversely correlated with BMI (r = -0.18, p = 0.001). The correlations between the Arabic and the English SBQ versions ranged from 0.25-0.96; p < 0.001 on weekdays and 0.50-0.90; p < 0.001 on weekends. Moderate to good reliability was also found between test and retest for all SBQ items and total score during weekdays (0.72 to 0.8), and weekends (0.64 to 0.87), with exception of the 7th item "play musical instrument", ICC = 0.46). Mean difference of test-retest of the Arabic SBQ was not significantly different from zero for the total sitting time of the Arabic SBQ (t = -0.715, P = 0.476). CONCLUSION: The Arabic SBQ had satisfactory levels of reliability, with total sitting time of the Arabic SBQ correlating significantly with sitting times derived from IPAQ-SF, IPAQ-LF, and the English SBQ versions. Hence, the Arabic SBQ can be used as a tool to measure sedentary behavior among adult Arabs aged between 18 to 30 years old in future epidemiologic and clinical practice.

Maternal obesity influences Birth Weight more than gestational Diabetes author.

BACKGROUND: Maternal obesity and gestational diabetes (GDM) are commonly encountered during pregnancy. Both conditions are independently associated with unfavorable pregnancy consequences. The objective of this study was to compare the effects of obesity and GDM on birth weight, macrosomia, and other adverse pregnancy outcomes. METHODS: This cohort study involved 531 women with a singleton pregnancy attending the Maternity and Children's Hospital, Medina, Saudi Arabia, between June 2014 and June 2015. Participants underwent a 75-g oral glucose tolerance test between 24 and 28 weeks. The International Association of Diabetes and Pregnancy Study Groups criteria were used for GDM diagnosis. BMI was assessed at the first antenatal visit, and obesity was defined as a BMI ≥30.0 kg/m2. All women were followed up until delivery. Women were divided into 4 groups: non-GDM nonobese (reference group), GDM nonobese, obese non-GDM, and obese GDM. Clinical characteristics and adverse pregnancy outcomes were compared. RESULTS: The mean age and BMI of the participants were 30.5 years and 29.3 kg/m2, respectively. GDM was diagnosed in 50.2% of the participants, and obesity was diagnosed in 47.8% of the participants. Obese women with GDM were the oldest and heaviest among all women. The mean birth weight increased in order among the four groups; it was highest in the infants in the obese GDM group, followed by those in the obese non-GDM, GDM nonobese and reference groups. Obesity and GDM alone or in combination were associated with higher rates of macrosomia and cesarean deliveries than the reference group. Neonatal intensive care unit (NICU) admission was higher in infants in the GDM nonobese and obese GDM groups. The frequency of low Apgar score was significantly higher in infants in the obese GDM group than in infants in the reference group. CONCLUSIONS: Maternal obesity seems to influence birth weight more than GDM, while GDM is associated with a greater risk of admission to the NICU. The combination of both conditions is associated with the greatest risk of adverse pregnancy outcomes.

Diabetic ketoacidosis precipitated by Coronavirus disease 2019 infection: Case series.

BACKGROUND: Coronavirus disease 2019 (COVID-19) has evolved into a devastating pandemic since December 2019. Saudi Arabia's first case was reported in March 2020. Subsequently, some 220,000 cases and 2000 deaths were recorded through July 2020. COVID-19 infection aggravates glycemic control and provokes acute hyperglycemic crises, according to some reports. We made the same observations in some of our patients diagnosed with COVID-19. However, we are unaware of any reported cases of diabetic ketoacidosis (DKA) among COVID-19 patients in Saudi Arabia. OBJECTIVE: Highlighting the significance of hyperglycemia on COVID-19 patient outcomes. METHODS: Five patients with DKA were admitted and diagnosed with COVID-19 based on real-time reverse transcription-polymerase chain reaction assays. Electronic medical records were reviewed and informed consent was obtained before reporting the index cases. RESULTS: Five patients presenting with DKA complicating a concurrent COVID-19 infection were reported. Three were known to have preexisting diabetes and 2 had newly diagnosed diabetes based on significantly elevated glycated hemoglobin levels at admission. Four recovered and were discharged to their homes and 1 had a complicated course and died. CONCLUSIONS: Our cases demonstrate that COVID-19 infection can trigger DKA. DKA can occur among patients who are known to have diabetes mellitus or appears as a first presentation. Clinicians should be extremely careful in checking for admission hyperglycemia and closely monitor respiratory status during fluid resuscitation of COVID-19-related DKA.

Higher rate of hyperglycemia than hypoglycemia during Ramadan fasting in patients with uncontrolled type 1 diabetes: Insight from continuous glucose monitoring system.

BACKGROUND: Patients with uncontrolled type 1 diabetes mellitus (T1DM) are at a high risk for Ramadan fasting and are exempt from fasting; however, most still insist on fasting. The aim of this study was to examine glucose level fluctuations in those patients during Ramadan fasting using a real-time continuous glucose monitoring system (RT-CGMS). METHODS: This pilot study involved adult patients with uncontrolled T1DM (HbA1c > 7%) who insisted on fasting during Ramadan in 2014 from Maternity and Children's Hospital, Medina, Saudi Arabia. A Medtronic RT-CGMS was used to monitor the participants' glucose levels for 3 consecutive days during fasting. RESULTS: The study included 22 patients (mean age 22 ±â€¯6 years, duration of diabetes 10.9 ±â€¯7.2 years, HbA1c level 9.3 ±â€¯1.2). All participants were using the basal-bolus insulin regimen, except for one patient who was on an insulin pump. Sensor glucose (SG) profiles typically followed a pattern that was characterized by an exaggerated increase after iftar, which was sustained overnight, and a second rapid rise after suhoor, with a prolonged glucose decay over the daylight hours. The average SG was 199 ±â€¯104.1 mg/dl, which was lower during fasting 188.4 ±â€¯103.41 mg/dl than during the eating hours 212.5 ±â€¯103.51 mg/dl (P = 0.00). There was a higher rate of hyperglycemia (48%) than hypoglycemia (10%). CONCLUSIONS: Patients with uncontrolled T1DM who fasted during Ramadan experienced a wide fluctuation of glucose levels between fasting and eating hours, exhibiting a greater tendency toward hyperglycemia. The long-term effects for this finding are not known and warrant further investigation.

Sex hormone binding globulin as a valuable biochemical marker in predicting gestational diabetes mellitus.

BACKGROUND: Circulating Sex hormone binding globulin (SHBG) levels are inversely associated with insulin resistance. This study was conducted to compare maternal serum SHBG level between pregnant women with normal glucose tolerance and those with gestational diabetes (GDM) and to investigate the roll of SHBG in GDM diagnosis. METHODS: This was a case controlled study of 90 pregnant women, 45 women with GDM and 45 matched controls, attending obstetrics clinic at Ohud Hospital, Madina, Saudi Arabia between April 2014 and March 2015. Measurement of serum SHBG levels by Enzyme-linked immunosorbent assay (ELISA) method were done between 24 and 28 weeks of gestation. The best cut-off point of SHBG to diagnose GDM was calculated in receiver operating characteristic curve. RESULTS: Compared with the control group, SHBG concentrations were significantly lower in the GDM group; median 23 nmol/L (18-30) vs. 78 nmol/L (65-96), p < 0.001). The cut off value 50 nmol/L of the SHBG had 90% sensitivity and 96% specificity to diagnose GDM. CONCLUSION: Patients with GDM have lower circulating levels of SHBG than normal glucose tolerance pregnant women. Circulating concentrations of SHBG represent a potentially useful new biomarker for prediction of risk of GDM beyond the currently established clinical and demographic risk factors.

Validity of the International Diabetes Federation risk stratification score of Ramadan fasting in individuals with diabetes mellitus.

OBJECTIVES: To assess the validity of the new International Diabetes Federation-Diabetes and Ramadan International Alliance (IDF-DAR) risk stratification tool for Ramadan fasting in predicting diabetic patients' ability to fast safely. METHODS: A prospective observational study was carried out during Ramadan 2022 at the Diabetes Center, King Fahad Hospital, Al-Madinah Al-Munawarah, Saudi Arabia. The IDF-DAR risk stratification tool was used to calculate fasting risk for diabetic patients pre-Ramadan. The patients were allocated into 3 categories: high, moderate, and low risk. Fasting was left up to the patients and their healthcare providers. Participants filled out a log-sheet each day of Ramadan showing whether they completed the fast. A final interview was carried out after Ramadan to assess patients' fasting experiences. RESULTS: We included 466 patients with diabetes: 79.4% with T2DM and 20.6% with T1DM. Based on the IDF-DAR score, 265 (56.9%) patients were classified as high risk, 115 (24.7%) as moderate risk, and 86 (18.4%) as low risk. Non-fasting the whole month of Ramadan was statistically relevant to the IDF-DAR risk stratification score. High-risk individuals were more likely to experience hypoglycemia and hyperglycemia than those with a moderate or low risk. But overall, 70.4% of people at moderate risk and 53.2% of the ones at high risk observed Ramadan's complete fast. CONCLUSION: The IDF-DAR has proven to be reliable and valid for predicting the risk of adverse events associated with fasting in diabetic patients. Nonetheless, it might overestimate the risk of fasting for some patients.

An update on the current characteristics and status of care for Muslims with type 2 diabetes fasting during Ramadan: the DAR global survey 2022.

BACKGROUND: Managing diabetes during Ramadan fasting is a challenge due lifestyle changes. We described the characteristics and patterns of care for type 2 diabetes mellitus (T2DM) during Ramadan 2020 and 2022. METHODS: Our study included multinational Muslims with T2DM who were during routine consultation. We collected data on demographics, fasting characteristics, and complications. Descriptive statistics, chi-square test, and multiple testing were performed. RESULTS: 12,529 patients participated. Mean age was 55.2 ± 11.8 years; 52.4% were females. Mean diabetes duration was 9.9 ± 7.4 years; 27.7% were with HbA1c >9% (75 mmol/mol) and 70% had complications. Metformin was the most used medication followed by insulin. 85.1% fasted ≥1 day; fasting mean duration was 27.6 ± 5.6 days. Hypoglycemia occurred in 15.5% of whom 11.7% attended emergency department or were hospitalized; this was significantly associated with age and/or duration of diabetes. Hyperglycemia occurred in 14.9% of whom 6.1% attended emergency department or were hospitalized and was also associated with age or duration of diabetes. 74.2% performed SMBG during fasting. 59.2% were educated on Ramadan fasting, with 89.7% receiving it during routine consultation. CONCLUSIONS: Ramadan fasting in T2DM is high. Multidisciplinary approach is required to mitigate complications. Our findings support current recommendations for safe fasting.

The goal of this survey was to describe the characteristics and current ways of care for Muslim patients with type 2 diabetes mellitus fasting during and after Ramadan 2020 and 2022. Most of the participants fasted a minimum of one day during Ramadan (85.1%). Overall, 15.5 and 14.9% reported low blood sugar levels or high blood sugar levels during fasting, respectively. Low blood sugar level was more reported in patients with older age, patients with longer diabetes duration, and women. High blood sugar level was more reported in patients with longer diabetes duration. Educational programs focusing on the risks occurring with fasting and practices that improve control of the disease will raise knowledge and awareness among patients with diabetes. Improving blood sugar control during Ramadan fasting remains a major need for both patients and healthcare providers who should collaborate to reduce the risk of diabetes-related problems.

Hypoglycemia unawareness among insulin-treated diabetic patients in Madinah, Saudi Arabia: prevalence and risk factors.

Background: Hypoglycemia unawareness (HU) is associated with significant risks. Screening for impaired awareness of hypoglycemia in patients with diabetes is important to minimize those risks. There are limited data on the prevalence of HU in patients with diabetes in Saudi Arabia (KSA). In the current study, we investigated the frequency of HU and its risk factors among insulin treated diabetic patients in Madinah, KSA. Methods: A cross-sectional study was conducted in a diabetes center and four primary healthcare centers at Madinha, KSA. Patients ≥14 years old with type 1 or type 2 diabetes treated with insulin for more than a year were included. HU was assessed by Clarke's and modified Pedersen-Bjergaard's scores. The risk factors for HU were determined. Results: Of the 413 included patients, 60.3% were women, and 60.8% were on insulin alone. One-third of the participants had T1DM, while 68.5% had T2DM, with median ages of 25 and 56 years, diabetes durations of 10 and 15 years, and durations of insulin use of 10 and 5 years, respectively. The prevalence of HU was 25.2% by Clarke's survey. The risk factors for HU were poor knowledge of the patient's latest HbA1c, type of insulin, and dose of insulin. Poor medical follow-up, previous stroke, and ischemic heart disease were the other risk factors for HU. When the modified Pedersen-Bjergaard method was used, the prevalence of HU was 48.9%. Conclusion: Despite the advances in diabetes management, HU continues to be prevalent among diabetic patients on insulin, and poor diabetes knowledge is a major risk factor. Diabetes education on self-management is of utmost importance to reduce hypoglycemia and HU.

Fasting Ramadan in patients with T1DM - Saudi Arabia versus other countries during the COVID-19 pandemic.

BACKGROUND AND AIMS: To compare Saudi Arabia with other countries regarding patient attitudes towards fasting Ramadan and complications related to fasting during the COVID-19 pandemic. METHODS: Data collected from Saudi Arabia and 12 other mostly Muslim majority countries, via physician administered questionnaire within post Ramadan 2020. RESULTS: 1485 Type1 diabetes (T1DM) patients analyzed; 705 (47.5%) from Saudi Arabia vs. 780 (52.5%) from other countries. 1056 (71.1%) fasted Ramadan; 636 (90.2%) of Saudi patients vs. 420 (53.8%) of other countries. Experiencing Ramadan during the COVID-19 pandemic did not affect the Saudi T1DM patients' decision to fast while it significantly influenced their decision in other countries (1.4 vs 9.9%, P < 0.001). More Saudi patients needed to break the fast due to a diabetes related complication compared to other countries (67.4% vs. 46.8%, p=<0.001). The mean number of days fasted in Saudi and other countries was 24 ± 7 and 23 ± 8 days respectively. Hypoglycemic events were more common among Saudi patients during Ramadan compared to other countries 72% and 43.6% (p < 0.001) respectively. There was a significant difference in timing; the largest peak for Saudi Arabia patients was after dawn (35% vs 7%, p < 0.001), while it was pre-sunset for the other countries (23 vs 54%, p = 0.595). Day time-hyperglycemia was also more common among Saudi patients (48.6% vs. 39%, p < 0.001), however it was a less likely cause to break the fast (25.6% vs 38.3%, p < 0.001). CONCLUSION: Observing the fast of Ramadan is extremely common among Saudi T1DM patients compared to other Muslim countries and was not affected by the COVID-19 pandemic. However, it was associated with higher frequency of hypoglycemic and hyperglycemic episodes.

Comparison of bone mineral density and Fracture Risk Assessment Tool in Saudi women with and without type 2 diabetes mellitus: A cross-sectional study.

OBJECTIVES: To compare the bone mineral density and the fracture risks in Saudi women with and without type 2 diabetes mellitus (T2DM). METHODS: This cross-sectional study was carried out at Taibah Early Diagnostic Center, Al Madinah Al Munawarah, Saudi Arabia. A total of 465 women with and without T2DM aged ≥40 years who visited the center for a dual-energy X-ray absorptiometry scan between December 2020 and July 2021 were randomly selected. The 10-year probabilities of major osteoporotic fracture (MOF) and hip fracture (HF) were calculated using the Abu Dhabi Fracture Risk Assessment Tool (FRAX) with and without adjustment for T2DM. The adjustment was made by setting rheumatoid arthritis as the equivalent risk for T2DM in the FRAX. Bone mineral density values and the FRAX scores were compared between women with T2DM and non-diabetes. RESULTS: Of 465 women, 214 had T2DM, and 251 were non-diabetics. The mean age of women was 59.42±7.9 years. There were no significant differences in mean age, menopausal status, height, weight, and body mass index between T2DM and non-diabetic women. Bone mineral density values and the unadjusted FRAX scores were comparable between the 2 groups. However, after adjusting FRAX for T2DM, the FRAX for MOF and HF became significantly higher in T2DM women (p=0.000 and p=0.004). CONCLUSION: In Saudi women with T2DM, unadjusted FRAX underestimated the risk of MOF and HF. Type 2 diabetes mellitus should be included as one of the clinical risk factors for fracture in future versions of the FRAX score.

Management of Primary Hyperparathyroidism With Severe Hypercalcemia During the COVID-19 Pandemic.

PURPOSE: In patients with primary hyperparathyroidism (PHPT) and severe hypercalcemia, parathyroidectomy remains the only curative therapy. During the coronavirus disease 2019 (COVID-19) pandemic, when many hospital visits are suspended and surgeries cannot be performed, the management of these patients represents a challenging clinical situation. This article presents a literature review and discussion of the pharmacologic management of PHPT and severe hypercalcemia, which can be used as a temporary measure during the COVID-19 pandemic until parathyroidectomy can be performed safely. METHODS: This narrative review was conducted by searching literature on the PubMed, Medline, and Google Scholar databases using the terms primary hyperparathyroidism, hypercalcemia, cinacalcet, bisphosphonates, denosumab, vitamin D, raloxifene, hormone replacement therapy, coronavirus, and COVID-19. FINDINGS: Appropriate monitoring and remote medical follow-up of these patients are essential until the resolution of the pandemic. Cinacalcet is the drug of choice for controlling hypercalcemia, whereas bisphosphonate or denosumab is the drug for improving bone mineral density. Combined therapy with cinacalcet and bisphosphonates or cinacalcet and denosumab should be considered when the effects on serum calcium and bone mineral density are simultaneously desired. IMPLICATIONS: Medical management of PHPT and severe hypercalcemia presents a reasonable alternative for parathyroid surgery during the COVID-19 outbreak and should be instituted until the pandemic ends and surgery can be performed safely.

Ramadan fasting in people with type 1 diabetes during COVID-19 pandemic: The DaR Global survey.

OBJECTIVES: The DaR Global survey was conducted to determine the impact of the COVID-19 pandemic on the intentions to fast and the outcomes of fasting in <18 years versus ≥18 years age groups with type 1 diabetes mellitus (T1DM). METHODS: Muslim people with T1DM were surveyed in 13 countries between June and August 2020, shortly after the end of Ramadan (23rd April-23rd May 2020) using a simple questionnaire. RESULTS: 71.1% of muslims with T1DM fasted during Ramadan. Concerns about COVID-19 were higher in individuals ≥18 years (p = 0.002). The number of participants who decided not to fast plus those who received Ramadan-focused education were significantly higher in the ≥18-year group (p < 0.05). Hypoglycemia (60.7%) as well as hyperglycemia (44.8%) was major complications of fasting during Ramadan in both groups irrespective of age. CONCLUSION: COVID-19 pandemic had minor impact on the decision to fast Ramadan in T1DM cohort. This was higher in the age group of ≥18 years compared to those <18 years group. Only regional differences were noted for fasting attitude and behavior among T1DM groups. This survey highlights the need for Ramadan focused diabetes education to improve glucose control and prevent complications during fasting.

Congestive heart failure and upper extremity deep vein thrombosis: A rare presentation of a pheochromocytoma.

Pheochromocytomas are rare catecholamine-secreting neoplasms, occurring in approximately 0.1-0.5% of the patients with hypertension. Typically, a pheochromocytoma presents with hypertension, a paroxysm of headaches, sweating, and palpitation. However, patients may also present with atypical clinical manifestations on rare occasions. This report presents a case involving a young woman who presented with two rare manifestations of pheochromocytomas: congestive heart failure and right upper extremity deep vein thrombosis (DVT). Her cardiomyopathy was completely resolved by surgical and medical therapy, while DVT was resolved with anticoagulation. Pheochromocytoma should be considered in case of sudden and unexplained cardiac failure and/or DVT. Pheochromocytoma-induced cardiomyopathy can be reversed with medical and/or surgical therapy for pheochromocytomas.

High rate of persistent/recurrent disease among patients with differentiated thyroid cancer in Saudi Arabia: factors affecting nonremission.

BACKGROUND AND OBJECTIVES: A fairly high number of patients with differentiated thyroid cancer (DTC) in our center had locally advanced disease at presentation and/or persistent disease after standard treatment. Therefore, we conducted a retrospective study to find the rate of successful ablation and remission and the factors affecting these outcomes. METHODS: The study included 100 consecutively treated patients (20 males, 80 females; median age 36 years) diagnosed with DTC. Univariate and multivariate logistic regression was used to evaluate the effect of risk factors on the persistence or recurrence of thyroid cancer. All patients underwent total thyroidectomy and had cervical lymph node dissection when indicated. All patients received sodium iodide I 131 ablation once or twice post surgery. Patients were followed clinically by neck ultrasound, (123)I whole body scan and by thyroglobulin measurements and other diagnostic tests as needed. RESULTS: Over a median follow-up of 7.6 years (range 7-10 years), ablation occurred in 93%, remission in 50%, disease persisted without remission in 41%, and 9% had recurrence after at least 1 year of remission. Papillary thyroid cancer was found in 76%, the follicular variant in 14%, other variants (tall cell and sclerosing types) in 2%, Hurthle cell carcinoma in 4%, and pure follicular thyroid cancer in 4%. Compared with patients in remission, patients with persistent/recurrent disease were older (mean 41 versus 31 years, P=.003), had higher postoperative thyroglobulin (193 versus 29 ng/mL, P=.04) and more advanced TNM staging (P=.005). Risk factors significant for non-remission were age >40 years (odds ratio 4.1, 95% CI 1.5-10.9 years, P=.003) and TNM stage other than 1 (odds ratio 5.5, 95% CI 1.9-16.3, P=.001). Only TNM Stage 1 was significant for remission in the multivariate analysis. CONCLUSION: The low remission rate in our DTC patients is probably due to more advanced disease at time of presentation. Early detection may, therefore, be essential in improving outcome.

Neck circumference as a marker of obesity and a predictor of cardiometabolic risk among Saudi subjects.

OBJECTIVES: To determine the optimal cutoff value for neck circumference (NC) that define overweight/obesity and assess its predictive potential for cardiometabolic risks (CMR) among Saudi subjects.  Methods: A cross sectional study of 785 adults recruited from a public health awareness campaign in Medina, Saudi Arabia during June 2015. Waist circumference (WC), NC, body mass index (BMI), blood pressure (BP), and random blood glucose (RBG) were assessed, and the presence of CMR were collected by a questionnaire. Pearson's correlation coefficients were used to evaluate the associations of NC with other anthropometric indices and CMR. The optimal cutoff value for NC to identify overweight/obesity was determined by receiver operating characteristic (ROC) curves. Results: There were significant correlations between NC and BMI, weight, WC, age, RBG, and BP. The area under the curve for NC and WC in the ROC analysis was 0.86 for men and 0.77 for women, and NC ≥39.25 cm for men and ≥34.75 cm for women were the best cutoff levels for identifying subjects with central obesity with an 89% sensitivity and a 71% specificity for men and an 80% sensitivity and a 65% specificity for women. These cutoff levels for NC were associated with a significantly increased risk for diabetes, dyslipidemia, and hypertension.  Conclusion: Neck circumference is positively correlated with BMI and WC, and can be used to identify overweight/obesity and predict CMR in Saudi individuals.

Five-year follow-up after clinical islet transplantation.

Islet transplantation can restore endogenous beta-cell function to subjects with type 1 diabetes. Sixty-five patients received an islet transplant in Edmonton as of 1 November 2004. Their mean age was 42.9 +/- 1.2 years, their mean duration of diabetes was 27.1 +/- 1.3 years, and 57% were women. The main indication was problematic hypoglycemia. Forty-four patients completed the islet transplant as defined by insulin independence, and three further patients received >16,000 islet equivalents (IE)/kg but remained on insulin and are deemed complete. Those who became insulin independent received a total of 799,912 +/- 30,220 IE (11,910 +/- 469 IE/kg). Five subjects became insulin independent after one transplant. Fifty-two patients had two transplants, and 11 subjects had three transplants. In the completed patients, 5-year follow-up reveals that the majority ( approximately 80%) have C-peptide present post-islet transplant, but only a minority ( approximately 10%) maintain insulin independence. The median duration of insulin independence was 15 months (interquartile range 6.2-25.5). The HbA(1c) (A1C) level was well controlled in those off insulin (6.4% [6.1-6.7]) and in those back on insulin but C-peptide positive (6.7% [5.9-7.5]) and higher in those who lost all graft function (9.0% [6.7-9.3]) (P < 0.05). Those who resumed insulin therapy did not appear more insulin resistant compared with those off insulin and required half their pretransplant daily dose of insulin but had a lower increment of C-peptide to a standard meal challenge (0.44 +/- 0.06 vs. 0.76 +/- 0.06 nmol/l, P < 0.001). The Hypoglycemic score and lability index both improved significantly posttransplant. In the 128 procedures performed, bleeding occurred in 15 and branch portal vein thrombosis in 5 subjects. Complications of immunosuppressive therapy included mouth ulcers, diarrhea, anemia, and ovarian cysts. Of the 47 completed patients, 4 required retinal laser photocoagulation or vitrectomy and 5 patients with microalbuminuria developed macroproteinuria. The need for multiple antihypertensive medications increased from 6% pretransplant to 42% posttransplant, while the use of statin therapy increased from 23 to 83% posttransplant. There was no change in the neurothesiometer scores pre- versus posttransplant. In conclusion, islet transplantation can relieve glucose instability and problems with hypoglycemia. C-peptide secretion was maintained in the majority of subjects for up to 5 years, although most reverted to using some insulin. The results, though promising, still point to the need for further progress in the availability of transplantable islets, improving islet engraftment, preserving islet function, and reducing toxic immunosuppression.

Macronutrients Imbalance and Micronutrient Deficiencies among Healthy Saudi Physicians in Al Madina, Saudi Arabia.

CONTEXT: Diet and nutrition are important factors in the promotion and maintenance of good health. Physicians are involved in medical nutrition therapy of their patients; however, little is known on how physicians are personally adherent to good nutrition. The aim of the study was to assess the nutritional practices of Saudi physicians. SUBJECTS AND METHODS: This is a pilot study that included 48 healthy Saudi physicians, of both genders, randomly selected from King Fahad Hospital, Madina, Saudi Arabia from June 2013 to December 2013. Self-reported dietary intake over 24 h was assessed. The adequacy of nutrient intake was evaluated by comparing the physicians' intake to the dietary reference intakes (DRI). RESULTS: The mean age of physicians was 41.6 ± 10 years, weight was 78 ± 20.2 kg, and body mass index was 27.76 ± 5.37 kg/m2. They reported adequate daily consumption of food energy with high intake of carbohydrate (178.5 ± 46.4%) of DRI and high fat and protein intake from animal sources with low fiber intake (34.9 ± 25.1%) of DRI. Daily intakes for most of the micronutrients were lower than recommended with the exception of phosphorus, Vitamin E, and Vitamin B12 with no significant difference between males and females, except for lower intake of iron and Vitamin D by females. Vitamin D was the most severe deficient vitamin; 46.1 ± 53.9% of DRI. CONCLUSIONS: Nutritional practices of the sampled group of Saudi Physicians were not optimal. They have a high prevalence of micronutrients deficiencies. In addition, they tend to consume less fiber, more carbohydrate, and food from animal sources. Actions are needed to control nutrition status in Saudi Arabia, including the adoption of healthy eating pattern early in life, extensive nutrition and health education, and intervention strategies.

Use of a real time continuous glucose monitoring system as an educational tool for patients with gestational diabetes.

BACKGROUND: Women with gestational diabetes mellitus (GDM) are required to control their blood glucose shortly after GDM diagnosis to minimize adverse pregnancy outcomes. A real time-continuous glucose monitoring system (RT-CGMS) provides the patient with continuous information about the alterations in levels of the blood glucose. This visibility may empower the patient to modify her lifestyle and engage in therapeutic management. The aim of this study was to determine whether a single application of RT-CGMS to pregnant women shortly after GDM diagnosis is useful as an educational and motivational tool. METHODS: This study was a prospective open label randomized controlled study conducted at Maternity and Children Hospital, Medina, Saudi Arabia. A total of 130 pregnant women with GDM were randomised to either blood glucose self-monitor alone (SMBG group) (n = 62) or in addition to SMBG, patients wore a Guardian(®) REAL-Time Continuous Glucose Monitoring System (Medtronic MiniMed) once for 3-7 days, within 2 weeks of GDM diagnosis (RT-CGMS group) (n = 68). The primary outcomes were maternal glycemic control and pregnancy outcomes. Secondary outcomes were the changes in parameters of glucose variability, which includes mean sensor readings, standard deviation (SD) of blood glucose, and area under the curve for hyper and hypoglycaemia at the end of the RT-CGMS application. RESULTS: HbA1c, mean fasting and postprandial glucose levels were similar in both groups at the end of the pregnancy. Pregnancy outcomes were comparable. However, there was significant improvement in the parameters of glucose variability on the last day of sensor application; both mean glucose and the SD of mean glycaemia were reduced significantly; P = 0.016 and P = 0.034, respectively. The area under the curve for hyper and hypoglycaemia were improved, however, the results were not statistically significant. CONCLUSION: Although a single application of RT-CGMS shortly after GDM diagnosis is helpful as an educational tool, it was not associated with improvement in glycemic control or pregnancy outcomes.
