Clinical practice recommendations for management of Diabetes Mellitus in Arab region: An expert consensus statement from Arab Diabetes Forum (ADF).

Prevalence of diabetes in Arab region has significantly increased, resulting in a significant economic burden on healthcare systems. This surge can be attributed to obesity, rapid urbanization, changing dietary habits, and sedentary lifestyles. The Arab Diabetes Forum (ADF) has established localized recommendations to tackle the region's rising diabetes prevalence. The recommendations, which incorporate worldwide best practices, seek to enhance the quality of treatment for people with diabetes by raising knowledge and adherence among healthcare providers. The guidelines include comprehensive recommendations for screening, diagnosing, and treating type 1 and type 2 diabetes in children and adults for better overall health results.

The American Thyroid Association risk stratification and long-term outcomes of differentiated thyroid cancer: a 20-year follow-up of patients in Saudi Arabia.

Background: Studies have reported differing factors associated with poor outcomes in patients with differentiated thyroid cancer (DTC). We aimed to describe our 20 years of experience in the management of thyroid cancer (TC) and identify predictors of treatment outcomes. Methods: We conducted a retrospective review of medical records of patients with TC seen in the Thyroid Center at King Saud University Medical City (KSUMC) in Riyadh, Saudi Arabia, between the years 2000 and 2020. Demographic and clinical data including pathological characteristics were collected. The American Thyroid Association (ATA) risk stratification was determined for all patients at the postoperative period as well as the response to therapy at the final follow-up visit. Results: A total of 674 patients (mean age: 47.21 years) with TC, 571 (84.7%) of which were women, were included. There were 404 (60.0%) patients with ATA low risk, 127 (18.8%) with intermediate risk, and 143 (21.2%) with high-risk histology. Overall, 461 patients (68.4%) had an excellent response to treatment, 65 (9.6%) had an indeterminate response, 83 (12.3%) had a biochemical incomplete response, and 65 (9.6%) had a structural incomplete response. Patients who had an excellent response were mostly ATA low risk (n = 318 of 431, 68.1%), whereas 40 of 65 patients (61.5%) of those with ATA high-risk histology had a structural incomplete response to treatment. There were significantly more women who had an excellent response compared with men. Obesity, lymphovascular invasion, and size of the tumor were significant predictors of worse outcomes to therapy. Conclusion: Tumor size, lymphovascular invasion, and obesity are strong predictors of a worse response to therapy among patients with TC. Patients with obesity should be carefully followed up regardless of their risk stratification in light of the recent compelling evidence associating obesity with thyroid cancer and its higher risk of a worse disease outcome. ATA risk stratification is well correlated with patient long-term outcomes.

Optimal Timing of Thyroid Hormone Replacement During Ramadan Fasting: A Randomized Controlled Trial in Patients with Prior Total Thyroidectomy.

Background: Fasting during Ramadan may be challenging for patients on levothyroxine (LT4), as the drug has a narrow therapeutic index and is administered on an empty stomach. The majority of Muslims who fast in Ramadan have two meals per day, iftar immediately after sunset and suhoor just before dawn. This study aimed at evaluating the impact of LT4 timing during Ramadan on thyrotropin (TSH) levels in patients who underwent total thyroidectomy to determine the best timing for intake and identify the predictors of TSH level changes. Methods: We conducted a parallel, double-blind, randomized controlled trial on Saudi patients diagnosed with hypothyroidism who underwent total thyroidectomy. Patients were required to have stable thyroid function for 6 months before the study period and fast ≥20 days of Ramadan. Participants were randomized to one of three times for LT4 administration: Group A, 30 minutes pre-iftar (n = 48); Group B, 3 hours post-iftar (n = 47); or Group C, 1 hour pre-suhoor (n = 47). The number of participants in the final analysis (excluding patients who dropped out) was as follows: Group A, (n = 31); Group B, (n = 34); and Group C, (n = 22). The changes in TSH and free thyroxine (fT4) levels two weeks before and after Ramadan were compared. Factors associated with a change in TSH levels were examined through multivariable analysis. Results: The TSH levels significantly increased in Group B (1.7 ± 1.8 mU/L vs. 3.1 ± 3.9 mU/L, p = 0.003) and Group C (2 ± 1.7 mU/L vs. 5.5 ± 10 mU/L, p = 0.011), but not Group A (1.8 ± 1.6 mU/L vs. 3.3 ± 4.2 mU/L, p = 0.158). The change in fT4 levels was comparable among the groups: Group A, 16.5 ± 2.7 mcg/dL vs. 15.9 ± 3.2 mcg/dL, p = 0.144; Group B, 15.8 ± 3.8 mcg/dL vs. 16.3 ± 3.6 mcg/dL, p = 0.620; and Group C, 17.5 ± 2.8 mcg/dL vs. 17.3 ± 3.9 mcg/dL, p = 0.770. In multivariable linear regression analysis, the following variables were significantly independently associated with TSH level change: age, weight gain, and the number of nonadherence days to LT4, where ß = -0.2, p = 0.026; ß = + 0.2, p = 0.026; and ß = + 0.5, p < 0.0001, respectively. Conclusions: Fasting patients who took LT4 pre-iftar did not experience significant changes in TSH, whereas those who took LT4 post-iftar or pre-suhoor did. The TSH changes during Ramadan may be associated with age (inverse association), weight gain, and the number of non-adherence to LT4 days. Trial Registration: SCTR Application no. 21122002.

Indirect comparison of efficacy and safety of insulin glargine/lixisenatide and insulin degludec/insulin aspart in type 2 diabetes patients not controlled on basal insulin.

BACKGROUND: Fixed-dose combinations of insulin glargine/lixisenatide (IGlarLixi) or insulin degludec/insulin aspart (IDegAsp) constitute treatment intensification in type 2 diabetes mellitus (T2D). OBJECTIVES: Compare efficacy and safety of IGlarLixi and IDegAsp (as intensification from basal insulin), by indirect comparison of phase III trials, in the absence of head-to-head trials. STUDY ELIGIBILITY CRITERIA: Studies comparing treatment intensification by once-daily IDegAsp or IGlarLixi to basal insulin. Data were extracted from two trials (BOOST: Intensify-Basal and LixiLan-L) retained for analysis. SYNTHESIS METHODS: Treatments were compared in terms of estimated treatment difference (ETD) in glycated haemoglobin (HbA1c), fasting and postprandial plasma glucose (FPG and PPG) change from baseline; in addition to hypoglycaemia incidence and weight changes. RESULTS: In a fixed-effect model examining HbA1c control, IGlarLixi was more effective than IDegAsp in reducing HbA1c (ETD 0.53%, P<0.0001]), PPG (ETD 2.65%, P<0.0001), and body weight (ETD 1.73kg, P<0.0001). Patients on IGlarLixi were more likely to achieve HbA1c<7% than patients on IDegAsp (odds ratio [OR]=0.40, P<0.0001), with lower incidence of hypoglycaemia (OR=1.33, P<0.001). LIMITATIONS: Limited number of studies; different baseline HbA1c and FPG. CONCLUSION: Once-daily IGlarLixi is more efficient than once-daily IDegAsp in controlling HbA1c and PPG and associates with greater weight loss and lower hypoglycaemia incidence.

The current reproduction number of COVID-19 in Saudi Arabia: is the disease controlled?

The infectiousness of COVID-19 is high among the susceptible population, making the calculation of the reproduction number (R) an essential step to implement preventive measures. We aim to estimate COVID-19 transmission to determine if the disease is successfully controlled or extra measured should be adopted to attain this goal. The daily incidence data of COVID-19 in Saudi Arabia from March 2nd, 2020, to April 4th, 2021, were obtained from the continuously updated Saudi Ministry of Health COVID-19 repository. To get accurate estimation of the situation over the last 4 months (from December 1st, 2020, to April 4th, 2021), we calculated the weekly (every 7 days) R starting from March 2nd, 2020, and till the last week of the available data. The calculated values of R were represented as median, first quantile (Q1), and third quantile (Q3). As early as the first week of December 2020, the median R was 0.81 (0.80-0.83) which means that each existing infected case would transmit infection to only one person. This was followed by fluctuations over the next few weeks around R value of 1, reaching its highest level of 1.45 (1.42-1.47) between December 31st, 2020, and January 6th, 2021. This was followed by a relatively steady decline over the following weeks, with some till mid-March where the R values started to slightly rise again. Social distancing, protective precautions, avoiding abuse of the partial lifting, expanding the screening process, and other Saudi measures sound to be successful and should be replicated in similar communities. This measure should be continued till the vaccination process is completed, to reduce the number of contacts and to avoid uncontrolled transmission of the disease.

Incidental finding of ovarian teratoma on post-therapy scan for papillary thyroid cancer and impact of SPECT/CT imaging.

A 41-year old woman post thyroidectomy and neck dissection is presented in this case. She initially presented goiter and an enlarged cervical lymph node. She had no family history of cancer or radiation therapy. She had total thyroidectomy and found to have papillary thyroid cancer (T4N1M0). Histopathology report revealed multifocal classical papillary thyroid carcinoma with lympho-vascular invasion, extra-thyroidal extension, and positive lymph nodes. She was treated with 6.5 Gigabecquerel (GBq) of 131Iodine. Whole-body scan showed uptake in the neck and large focus in the left lower abdomen. Single-photon emission computed tomography SPECT/CT demonstrated a round shaped mass in the left pelvis. Pathology revealed cystic teratoma with benign thyroid tissue (struma ovarii), and no malignancy. Two months later, she had the second treatment with 5.5 GBq 131Iodine. Her follow-up stimulated and non-stimulated thyroglobulin levels were significantly lower, and there was no abnormal uptake in the follow-up scan.

Este é o caso de uma mulher de 41 anos de idade, com pós-tireoidectomia e dissecção da área do pescoço. Ela inicialmente apresentou bócio e um linfonodo cervical aumentado. Não tinha histórico familiar de câncer ou tratamento com radiação. Ela foi submetida a uma tiroidectomia total e se observou um carcinoma papilar de tiroide (T4N1M0). Os achados histopatológicos revelaram carcinoma papilar multifocal clássico com invasão linfovascular, extensão extratiroideana e linfonodos positivos. Ela foi tratada com 6.5 Gigabecquerel (GBq) de Iodo131. A tomografia de corpo inteiro mostrou captação na área do pescoço e um grande foco no abdômen inferior esquerdo. A tomografia computadorizada por emissão de fóton único SPECT/CT demonstrou uma massa arredondada na pelve esquerda. A análise patológica revelou um teratoma cístico com tecido tiroideano benigno (struma ovarii) e nenhuma malignidade. Dois meses depois, ela foi submetida a um segundo tratamento com 5.5 GBq de Iodo131. O acompanhamento dos níveis de tireoglobulina estimulada e não estimulada foi significativamente mais baixo e não houve captação anormal na tomografia seguinte.
