Abstract After completing treatment for head and neck cancer (HNC), patients often face oral complications like oral pain, limited mouth opening and dry mouth which significantly reduce their oral health related quality of life (OHRQoL). These issues impact their overall well-being, social activities and long-term survival. The primary objective of this study was to evaluate OHRQoL and its association with sociodemographic characteristics, oral hygiene practices and oral clinical parameters such as oral hygiene status and oral mucositis grade in patients who have completed treatment for head and neck cancer. This cross-sectional study involved 79 HNC-treated patients within first year after completion of cancer treatment attending ENT and dental clinics at outpatient department (OPD) setting in Karachi. Data was collected electronically using structured questionnaire comprising of EORTC QLQ H&N – 35 to measure OHRQoL, patients were also examined for oral hygiene status using oral hygiene index- simplified (OHI-s) and oral mucositis grade using WHO oral mucositis scale. Multiple linear regression was used to test OHRQoL associations with the sociodemographic and different clinical factors. The result showed an overall mean score for oral health related quality of life (OHRQoL) of 25.02 ± 15.86 (95% CI 21.46–28.57), with difficulty in mouth opening 53.16 ± 18.88 and dry mouth 45.14 ± 24.48 being predominant concerns for decline in the OHRQoL in the population. Male predilection was observed among participants n = 60 (75.9%), majority of the participants n = 41 (51.9%) were below 52 years of age. n = 63 (80%) participants received radiotherapy alongside surgery and chemotherapy. Most of participants n = 66 (83.5%) experienced moderate to severe oral mucositis with poor oral hygiene status n = 56 (71%). Significant associations were found between OHRQoL and BMI, OH status, marital status, monthly income, gender and fluoride toothpaste (p

Aims: The current study evaluated the demographics, clinical characteristics, treatment patterns, and economic burden of patients with type 2 diabetes mellitus (T2DM) with comorbidities (heart failure [HF], chronic kidney disease [CKD], and cardiovascular disease [CVD] without HF) in Dubai, United Arab Emirates (UAE). Methods: This observational, retrospective study collected data from January 01, 2014, to December 31, 2019, from the Dubai Real-World Claims Database (adults ≥18 years; at least 1 T2DM diagnosis claim). Patients were stratified into 5 cohorts: T2DM alone (cohort 1), T2DM and CKD (cohort 2), T2DM and CVD without CKD and HF (cohort 3), T2DM and HF (cohort 4), and T2DM with HF and CKD (cohort 5). An evaluation of demographics and clinical characteristics during pre-index period, as well as treatment patterns, healthcare resource utilization, and costs during the post-index period was conducted. Results: The sample had 374,271 patients with T2DM (age 43–56 years; male [72–84%]). Patients in cohorts 4 and 5 had Deyo-Charlson Comorbidity Index scores of 4.4 and 5.8, respectively. General practitioners (GPs) routinely prescribed biguanides for patients in cohorts 1–4 (24–38%), and insulin to patients in cohort 5 (27.7%). Prescription rates of novel antihyperglycemic drugs, such as glucagon-like peptide-1 (GLP-1 RA), were very low (∼2–8%) even in cohorts with cardiovascular and renal comorbidities (cohorts 2–5). A similar observation was noted with prescribing rates (0.6–4.4%) of sodium-glucose cotransporter-2 inhibitors (SGLT-2i) in cohorts 2–5. Endocrinologists preferred to prescribe GLP-1 RA and SGLT2i to T2DM patients with comorbidities. During the 5-year study period, median outpatient claims were the highest in cohort 5 (8.0 [range, 1.0–168.0]), followed by cohort 2 (5.5 [range, 1.0–52.0]). The median cost for inpatient claims was higher in cohort 5 (16,429 [range, 3,732–29,126] AED) compared to other cohorts. The median cost for drugs and procedures was highest in cohort 5 (4,525 [range, 38–31,546] AED and 2,297 [range, 56–105,074] AED, respectively). Conclusion: Continued and increased usage of drugs such as SGLT2i and GLP-1 RA with proven cardiorenal benefits could improve long-term outcomes and reduce associated healthcare costs in patients with T2DM and comorbidities in Dubai, UAE.

Introduction: Myosin IXB (MYO9B) is an unconventional myosin with RhoGAP activity and thus is a regulator of actin cytoskeletal organization. MYO9B was previously shown to be necessary for skeletal growth and health and to play a role in actin-based functions of both osteoblasts and osteoclasts. However, its role in responses to mechanical stimulation of bone cells has not yet been described. Therefore, experiments were undertaken to determine the role of MYO9B in bone cell responses to mechanical stress both in vitro and in vivo.Methods: MYO9B expression was knocked down in osteoblast and osteocyte cell lines using RNA interference and the resulting cells were subjected to mechanical stresses including cyclic tensile strain, fluid shear stress, and plating on different substrates (no substrate vs. monomeric or polymerized collagen type I). Osteocytic cells were also subjected to MYO9B regulation through Slit-Robo signaling. Further, wild-type or Myo9b−/− mice were subjected to a regimen of whole-body vibration (WBV) and changes in bone quality were assessed by micro-CT.Results: Unlike control cells, MYO9B-deficient osteoblastic cells subjected to uniaxial cyclic tensile strain were unable to orient their actin stress fibers perpendicular to the strain. Osteocytic cells in which MYO9B was knocked down exhibited elongated dendrites but were unable to respond normally to treatments that increase dendrite length such as fluid shear stress and Slit-Robo signaling. Osteocytic responses to mechanical stimuli were also found to be dependent on the polymerization state of collagen type I substrates. Wild-type mice responded to WBV with increased bone tissue mineral density values while Myo9b−/− mice responded with bone loss.Discussion: These results demonstrate that MYO9B plays a key role in mechanical stress-induced responses of bone cells in vitro and in vivo.

Introduction: While ample evidence on improved glycemic control, weight reduction, and lowered blood pressure (BP) with sodium-glucose cotransporter type 2 inhibitors (SGLT2is) exists, real-world data on the potential benefit of SGLT2i on the diabetic population in the Middle East are lacking. The aim of our study was to describe the glycemic control, changes in body weight, body mass index (BMI), lipid profile, and BPs in patients receiving dapagliflozin with other antidiabetic medication. Methods: The REWARD study was a multicenter, post-authorization, prospective, open-label, noninterventional, real-world, cohort study. We enrolled 511 adult, type 2 diabetes mellitus patients on antidiabetic medications. These patients were started on dapagliflozin and followed up for 1 year to assess changes in their clinical and laboratory outcomes. Results: The mean HbA1c decreased significantly from 8.5 ± 1.6% at baseline to 7.6 ± 1.3% after 12 months (p value
