Disability attitudes in healthcare scale: translation and cross-cultural validation into Arabic using various medical samples.

PURPOSE: Cross-cultural adaptation of the Disability Attitudes in Health Care Scale (DAHCS) into Arabic to assess the attitude toward people with disabilities. The objective of this study was to: firstly, translate and cross-culturally adapt the DAHCS into Arabic and secondly, assess its psychometric properties. Further, the goal was to investigate bachelor medical students' and doctors' attitude toward people with disabilities and highlight the need to establish the scale's reliability and validity by employing various samples. METHODS: A convenience sample of 201 medical students and 105 doctors was used. Arabic DAHCS factors were extracted and confirmed by Exploratory Factor Analysis (EFA), and Confirmatory Factor Analysis (CFA). RESULTS: The findings revealed that medical professionals and students hold a positive attitude toward people with disabilities. The Mann-Whitney U and Kruskal-Wallis tests revealed no significant differences in the study's variables. EFA identified four factors. CFA showed a good fit to the model. Also, convergent and discriminant validity were achieved. Cronbach's Alpha and McDonald's Omega values for all factors were satisfactory. However, the study found a low value of Cronbach's Alpha and Omega for the fourth factor. CONCLUSIONS: The DAHCS was cross-culturally adapted into the Arabic language and its validity and reliability were achieved.

The Arabic version of the Disability Attitudes in Health Care Scale (DAHCS) demonstrated sufficient validity and reliability evidence to assess the Arabic-speaking healthcare students' and doctors' perceptions and attitudes towards people with disabilities.Those who educate medical students and provide rehabilitation training may find the DAHC useful.The DAHC is a specific scale to measure the attitude toward people with disabilities compared to other generic scales.

Effect of vasopressin injection technique on ovarian reserve during laparoscopic cystectomy of ovarian endometriomas: a systematic review and meta-analysis of randomized controlled trials.

INTRODUCTION: To evaluate the effect of injecting vasopressin during laparoscopic excision of ovarian endometriomas on ovarian reserve. EVIDENCE ACQUISITION: Four different databases (PubMed, Cochrane Library, Scopus, and ISI Web of Science) were searched to identify relevant studies in March 2023. We selected randomized controlled trials (RCTs) that compared vasopressin injection in the intervention group versus no injection of vasopressin in the control group among women undergoing laparoscopic cystectomy of ovarian endometriomas. The main outcomes were the amount of bleeding, number of coagulation events, and levels of serum anti-Müllerian hormone (AMH) and follicle-stimulating hormone (FSH). The available data were extracted and analyzed in a meta-analysis model using RevMan software. EVIDENCE SYNTHESIS: Seven RCTs, involving a total number of 478 patients, were included in our study. The vasopressin group had significantly reduced blood loss amount and number of coagulation events compared to the control group (P=0.004 and P=0.005). There was a significant improvement in the AMH levels within 6 months after surgery in the vasopressin group (MD=0.52, 95% CI: 0.11, 0.93, P=0.01). In addition, the FSH levels within 6 months after laparoscopic cystectomy were significantly reduced with vasopressin injection. CONCLUSIONS: Vasopressin injection during laparoscopic cystectomy of ovarian endometriomas is effective in reducing blood loss amount and frequency of coagulation, as well as protecting the ovarian reserve. More trials are encouraged to confirm our findings.

CD133-Dependent Activation of Phosphoinositide 3-Kinase /AKT/Mammalian Target of Rapamycin Signaling in Melanoma Progression and Drug Resistance.

Melanoma frequently harbors genetic alterations in key molecules leading to the aberrant activation of PI3K and its downstream pathways. Although the role of PI3K/AKT/mTOR in melanoma progression and drug resistance is well documented, targeting the PI3K/AKT/mTOR pathway showed less efficiency in clinical trials than might have been expected, since the suppression of the PI3K/mTOR signaling pathway-induced feedback loops is mostly associated with the activation of compensatory pathways such as MAPK/MEK/ERK. Consequently, the development of intrinsic and acquired resistance can occur. As a solid tumor, melanoma is notorious for its heterogeneity. This can be expressed in the form of genetically divergent subpopulations including a small fraction of cancer stem-like cells (CSCs) and non-cancer stem cells (non-CSCs) that make the most of the tumor mass. Like other CSCs, melanoma stem-like cells (MSCs) are characterized by their unique cell surface proteins/stemness markers and aberrant signaling pathways. In addition to its function as a robust marker for stemness properties, CD133 is crucial for the maintenance of stemness properties and drug resistance. Herein, the role of CD133-dependent activation of PI3K/mTOR in the regulation of melanoma progression, drug resistance, and recurrence is reviewed.

Mechanisms of Melanoma Progression and Treatment Resistance: Role of Cancer Stem-like Cells.

Melanoma is the third most common type of skin cancer, characterized by its heterogeneity and propensity to metastasize to distant organs. Melanoma is a heterogeneous tumor, composed of genetically divergent subpopulations, including a small fraction of melanoma-initiating cancer stem-like cells (CSCs) and many non-cancer stem cells (non-CSCs). CSCs are characterized by their unique surface proteins associated with aberrant signaling pathways with a causal or consequential relationship with tumor progression, drug resistance, and recurrence. Melanomas also harbor significant alterations in functional genes (BRAF, CDKN2A, NRAS, TP53, and NF1). Of these, the most common are the BRAF and NRAS oncogenes, with 50% of melanomas demonstrating the BRAF mutation (BRAFV600E). While the successful targeting of BRAFV600E does improve overall survival, the long-term efficacy of available therapeutic options is limited due to adverse side effects and reduced clinical efficacy. Additionally, drug resistance develops rapidly via mechanisms involving fast feedback re-activation of MAPK signaling pathways. This article updates information relevant to the mechanisms of melanoma progression and resistance and particularly the mechanistic role of CSCs in melanoma progression, drug resistance, and recurrence.

Effects of letrozole alone or in combination with gonadotropins on ovulation induction and clinical pregnancy in women with polycystic ovarian syndrome: a systematic review and meta-analysis of randomized controlled trials.

OBJECTIVE: To compare letrozole in combination with gonadotropins versus letrozole monotherapy in ovulation induction and clinical pregnancy among infertile women with polycystic ovarian syndrome (PCOS). METHODS: Several databases were searched for available clinical trials from inception until March 2023. We selected randomized controlled trials (RCTs) that compared sequential letrozole/gonadotropin versus letrozole alone among infertile women who met the Rotterdam criteria for PCOS. RevMan software was used to perform our meta-analysis. Our primary outcomes were ovulation and clinical pregnancy rates. Our secondary outcomes were endometrial thickness, number of mature follicles (diameter ≥ 18 mm), and incidence of miscarriage and ovarian hyperstimulation syndrome (OHSS). RESULTS: Six RCTs were retrieved with a total number of 723 patients. The ovulation and clinical pregnancy rates were significantly higher among the letrozole/gonadotropin group versus the letrozole monotherapy group (p < 0.001). In addition, there were significant improvements in endometrial thickness and number of mature follicles in the letrozole/gonadotropin group. There were no significant differences between the two groups regarding incidence of miscarriage and ovarian hyperstimulation syndrome. CONCLUSION: Letrozole in combination with gonadotropin is superior to letrozole alone in improving ovulation induction and clinical pregnancy among PCOS patients. More trials are required to confirm our findings.

Addressing Occupational Back Pain: A Systematic Review of Preventive and Therapeutic Strategies.

Occupational back pain has emerged as a significant public health concern. Despite several efforts to mitigate the adverse effects of occupational back pain, this issue still persists across the globe. This systematic review summarizes the preventive and therapeutic options available for managing occupational back pain. A systemic search was carried out in various databases including PubMed, Web of Science, CINAHL Ultimate, and Scopus to identify relevant literature. The search was also extended to Google Scholar to identify more relevant studies. A combination of keywords was used during the search. Studies were included if they focused on occupational back pain, investigated preventive and treatment options, and were published in English. A total of 20 relevant studies, including 62,176 participants, were included in this systemic review. Out of these 20 studies, 10 were randomized control trials, four were cross-sectional studies, two were longitudinal studies, one was a single-blinded clinical study, two were prospective studies, and the remaining one was a pilot study. This systemic review identified various interventions to improve occupational back pain. The common therapeutic strategies included educational programs, physio and rehab interventions, acupuncture, mixed treatment strategies, reflexology, massage, yoga, active physical therapy, and real-time occupational internet-based interventions. Some studies also reported the effectiveness of opioid therapy and non-steroidal anti-inflammatory drugs for managing back pain. Findings indicated that these therapies effectively reduced occupational back pain and improved quality of life. However, opioid therapy uses also raised safety concerns. The findings of this systemic review highlight the importance of adopting evidence-based strategies to address occupational back pain effectively.

Chemical Kinetic Method for Active-Site Quantification in Fe-N-C Catalysts and Correlation with Molecular Probe and Spectroscopic Site-Counting Methods.

Mononuclear Fe ions ligated by nitrogen (FeNx) dispersed on nitrogen-doped carbon (Fe-N-C) serve as active centers for electrocatalytic O2 reduction and thermocatalytic aerobic oxidations. Despite their promise as replacements for precious metals in a variety of practical applications, such as fuel cells, the discovery of new Fe-N-C catalysts has relied primarily on empirical approaches. In this context, the development of quantitative structure-reactivity relationships and benchmarking of catalysts prepared by different synthetic routes and by different laboratories would be facilitated by the broader adoption of methods to quantify atomically dispersed FeNx active centers. In this study, we develop a kinetic probe reaction method that uses the aerobic oxidation of a model hydroquinone substrate to quantify the density of FeNx centers in Fe-N-C catalysts. The kinetic method is compared with low-temperature Mössbauer spectroscopy, CO pulse chemisorption, and electrochemical reductive stripping of NO derived from NO2- on a suite of Fe-N-C catalysts prepared by diverse routes and featuring either the exclusive presence of Fe as FeNx sites or the coexistence of aggregated Fe species in addition to FeNx. The FeNx site densities derived from the kinetic method correlate well with those obtained from CO pulse chemisorption and Mössbauer spectroscopy. The broad survey of Fe-N-C materials also reveals the presence of outliers and challenges associated with each site quantification approach. The kinetic method developed here does not require pretreatments that may alter active-site distributions or specialized equipment beyond reaction vessels and standard analytical instrumentation.

Level of knowledge and quality of life among Saudi caregivers of Parkinson's disease patients: A study from a tertiary hospital in Riyadh, Saudi Arabia.

Purpose: We aimed to assess the family caregivers' level of knowledge and attitudes about Parkison's disease (PD), identify factors affecting their knowledge, evaluate their quality of life (QoL) and factors influencing it and to define the effect of PD on activities of daily living (ADLs) of PD patients. Method: We developed and validated a questionnaire to assess the level of knowledge and attitudes of family caregivers toward PD, effects of PD on caregivers' QoL as well as its effects on activities of daily living (ADLs) of patients from the caregivers' perspective. A scoring system was utilized and SPSS was used to evaluate the differences in responses between the groups; p < 0.05 indicated statistical significance. Results: 69 caregivers and their corresponding patients were included in the study. Family caregivers had a low level of knowledge, as reflected by a mean score of 3.45 out of 8. However, 62.3% were aware of all medications used by their patients. Additionally, the level of knowledge was associated with caregivers' gender as 57.1% of the female caregivers had medium PD knowledge scores while 58.5% of the male had low scores (p = 0.038). The level of knowledge was also associated with daily caregiving hours as only 44.5% of caregivers whom spending 0-5 h/day had medium and high knowledge scores while greater proportions with same scoring levels were found among those providing care > 5 h/day (75.0% in > 5-10 hrs; 52.4% in > 10-24 hrs; p = 0.024). Most caregivers confirmed their QoL had declined, yet the male caregivers had better QoL than females (p = 0.026). Longer caregiving time was associated with decline (p = 0.016) and severe effect on QoL of caregivers (p = 0.04). Conclusion: Caregivers of PD patients had a low level of knowledge. Female caregivers had significantly higher level of PD knowledge than their male counterparts. Low level of PD knowledge was significantly associated with shorter caregiving time per day. Longer caregiving time was significantly associated with a decline in caregivers' QoL. Increasing awareness and knowledge among caregivers is necessary to ensure better treatment outcomes and improve the QoL of both caregivers and patients.

Perception and clinical practice regarding mucus clearance devices with chronic obstructive pulmonary disease: a cross-sectional study of healthcare providers in Saudi Arabia.

OBJECTIVES: Clearing secretions from the airway can be difficult for people with chronic obstructive pulmonary disease (COPD). Mucus clearance devices (MCDs) are an option in disease management to help with this, but healthcare provider awareness and knowledge about them as well as current clinical practice in Saudi Arabia are not known. DESIGN: A cross-sectional online survey consisting of four themes; demographics, awareness, recommendations and clinical practice, for MCDs with COPD patients. SETTING: Saudi Arabia. PARTICIPANTS: 1188 healthcare providers including general practitioners, family physicians, pulmonologists, nursing staff, respiratory therapists and physiotherapists. PRIMARY OUTCOME MEASURES: Healthcare providers' level of awareness about MCDs, and the identification of current clinical practices of COPD care in Saudi Arabia. RESULTS: 1188 healthcare providers (44.4% female) completed the survey. Regarding devices, 54.2% were aware of the Flutter, 23.8% the Acapella and 5.4% the positive expiratory pressure mask. 40.7% of the respondents identified the Acapella, and 22.3% the Flutter as first choice for COPD management. 75% would usually or always consider their use in COPD patients reporting daily difficulty clearing mucus, whereas 55.9% would sometimes or usually consider the use of MCDs with COPD patients who produced and were able to clear mucus with cough. In clinical practice, 380 (32%) of the respondents would prescribe MCDs, 378 (31.8%) would give MCDs without prescriptions, 314 (26.4%) would not provide them at all and 116 (9.8%) would only advise patients about them. CONCLUSION: Healthcare providers are aware of the existence of MCDs and their benefits for sputum clearance and believe that MCDs are beneficial for sputum clearance in some COPD patients. TRIAL REGISTRATION NUMBER: ISRCTN44651852.

Impact of Osteoporosis in Postmenopausal Women With Primary Knee Osteoarthritis.

BACKGROUND: Although knee osteoarthritis (OA) and osteoporosis (OP) are common age-related bone disorders, the association between the two conditions remains indefinable. The aim of the present study is to investigate a possible relationship between the two conditions in post-menopausal women. METHODOLOGY: A cross-sectional study was conducted at King Khalid University Hospital, Riyadh, Saudi Arabia, after obtaining IRB approval. The study included all post-menopausal female patients above 50 years of age, who underwent dual-energy X-ray absorptiometry (DXA) scans between January 2019 and July 2021 and have clear radiological data regarding knee OA. For our study, 487 ladies satisfied our inclusion criteria with an age range of 50-94 years (mean 64.67 ±8.4). The severity of knee OA was determined according to the Kellgren and Lawrence (KL) grading system. RESULTS: The mean age and weight of all patients showed a significant association with knee OA. There was no significant association between bone quality and all parameters of bone mineral density (BMD) and T-score with the presence of knee OA. The mean age, height, weight, and BMI have a significant relationship with OP. Grade 3 of the KL classification system for knee OA is the only grade that showed a significant relationship with the presence of OP. The status of bone quality, BMD, and T-score parameters have no significant relationship with the severity subgrouping of knee OA. The BMD and the T-score of the right femoral neck have a significant correlation with BMI, which is linked to the presence of knee OA. CONCLUSION: We didn't find a clear relationship between OP or BMD and the presence of knee OA. However, our findings demonstrated that BMD, T-score of the right femoral neck, and BMI can all be utilized as predictors for the development and progression of knee OA. We recommend considering the many potential confounding variations when describing a relationship between OP and OA.

Effect of Gender on Postoperative Outcome and Duration of Ventilation After Coronary Artery Bypass Grafting (CABG).

INTRODUCTION: The study assessed coronary artery bypass grafting (CABG) postoperative outcomes and associated factors in Saudi male and female patients. This was a retrospective cohort of patients who underwent CABG at the King Abdulaziz University Hospital (KAUH), Jeddah, Saudi Arabia, from January 2015 to December 2022.  Results: We included 392 patients, of whom 63 (16.1%) were female. Female undergoing CABG were significantly older (p=0.0001), had a significantly higher incidence of diabetes (p=0.0001), obesity (p=0.001), hypertension (p=0.001), and congestive heart failure (p=0.005), with a smaller body surface area (BSA) (p=0.0001) than male. Though renal dysfunction, previous cerebrovascular accident/transient ischemic attack (CVA/TIA), and myocardial infarction (MI), incidences were similar in both genders. Females were at significantly higher risk of mortality (p=0.0001), longer hospital stay (p=0.0001), and prolonged ventilation (p=0.0001). Preoperative renal dysfunction was the only statistically significant predictor of postoperative complications (p=0.0001). Female gender and preoperative renal dysfunction, were significant independent predictors of postoperative mortality and prolonged ventilation (p=0.005). CONCLUSION: This study's findings indicated that females have worse CABG outcomes and a higher risk of morbidities and complications. Uniquely our study showed a higher incidence of prolonged ventilation in females postoperatively.

Chances of Liver Transplantation in a Patient With Transaldolase Deficiency Complicated by Hepatopulmonary Syndrome.

Eyaid's syndrome or Transaldolase Deficiency (TD) (OMIM 606003) is a rare autosomal recessive inborn error of metabolism. In this report, we describe the case of an eight-year-old Saudi girl with a history of hepatosplenomegaly since infancy, who presented to the emergency department for a short history of cough and worsening cyanosis. She had growth retardation, facial dysmorphia, cardiac defect, neutropenia, and thrombocytopenia, besides hepatosplenomegaly. A thorough investigation led to the diagnosis of hepatopulmonary syndrome and whole exome sequencing showed a homozygous frameshift variant in the TALDO1gene, c.793del, p.Gln265fs. Thus, the patient was diagnosed with TD complicated with hepatopulmonary syndrome, and the indication of liver transplantation was discussed.

Aplasia Cutis Congenita of the Lower Limb: A Case Report.

Aplasia cutis congenita type VI is a genetic disorder that presents with congenital skin absence, blistering, and nail abnormalities. We present the case of a male newborn who presented with an absence of skin in the entire left leg and the lower part of the left thigh. On the second day of life, he had new skin lesions that started to appear over the fingernail beds, nasal bridge, thighs, and buttocks. There were no other associated anomalies such as pyloric atresia, renal abnormalities, or ureteral stenosis. A diagnosis of Bart's syndrome was made based on clinical diagnosis and previous presentation in the family. The patient developed sepsis and osteomyelitis of the lower limb and eventually died.

Prevalence of post-COVID symptoms of obsessive-compulsive disorder in Saudi Arabia.

OBJECTIVES: To determine the prevalence of Obsessive-Compulsive Disorder (OCD) symptoms in patients who have survived COVID-19. METHODS: The study used an observational cross-sectional design between July and October 2021. The target population was adult patients who had confirmed COVID-19 infection prior to joining the study, OCD symptoms were assessed using the Arabic OCD scale created by Abohendy and colleagues, which included 83 questions covering 12 different domains and was administired online. RESULTS: A total of 356 patients were included in the analysis. Approximately 9.0% and 1.7% of the patients had a history of psychiatric disease and OCD diagnosis (respectively). The total symptom score was 32.8%. The most frequently reported domains were rumination of ideas (55.5%), re-checking compulsions (37.0%), and slowness (34.0%), while the least frequently reported domains included obsessive impulses (26.3%), obsessive images (26.5%), and religious compulsions (26.8%). Unlike other domains, the purity and cleanliness compulsions scores were significantly higher than the scale reference population. A higher total symptom score was observed in psychiatric patients (p=0.004) and, to a lesser extent, in OCD patients (p=0.250). CONCLUSION: Overall, OCD symptoms, including cleanliness and fear of disease obsessions, tend to be higher in psychiatric and OCD patients, these findings are valuable for future studies.

Morphometry of Conus Medullaris in the Saudi Population and Its Clinical Importance.

Objective The objective of this article is to evaluate the morphometry and termination of conus medullaris (CM) in the eastern province of Saudi Arabia. Methodology The lumbar spine magnetic resonance imaging (MRI) scans of 179 citizens of Saudi Arabia were selected and divided into males and females. Parameters such as the level of termination of CM, the length/width of CM, and its termination were reported. Results The maximum number of males and females were observed in the less than 20 years age group as 23 (25.5%) and 22 (24.7%), respectively. The termination level of CM was at the (first lumbar vertebra) L1 vertebra in 51.4% of the Saudi population. The level of termination of CM is below the (second lumbar vertebra) L2 level in one patient at L3, L3-L4, L5, and L5-S1 levels. On comparing the length of CM, no statistically significant difference was observed between the different levels of the vertebra. However, there was a statistically significant difference between the width and the CM termination (p=0.02). The various age groups and CM termination had no statistically significant correlation (p=0.47). Conclusion The most common level of termination of conus medullaris was at the L1 vertebra. The level of CM termination is strongly associated with the width of CM.

A bibliometric review on the top 20 cited articles in the Jackson heart study.

Background: Cardiovascular diseases are higher in African American population, and in the past three decades, less decline in mortality was observed in African Americans compared with white Americans American health disparities resulted in establishing one of the largest single-site investigations to examine causes of cardiovascular diseases in African American population, namely the Jackson Heart Study (JHS). Methods: In January 2020, we used the jacksonheartstudy.org website to obtain the list of publications produced by the JHS from 1999 to 2018. The citation's frequency was obtained for 455 articles using the search engine "google.com". The top 20 cited articles were characterized based on the first author's name, the month and year of publication, and the journal's name and its impact factor. Results: The frequency of citations for the 20 most-cited articles in the Jackson heart study ranged from 282 to 5545. The average number of citations was 1045.60. The top 20 articles were represented in 8 different peer-reviewed journals. Conclusion: The top 20 cited articles in the JHS were in the genetics field and were all observational in type. Future direction of the JHS should be directed toward well established interventional studies.

Molecular Catalyst Synthesis Strategies to Prepare Atomically Dispersed Fe-N-C Heterogeneous Catalysts.

We report a strategy to integrate atomically dispersed iron within a heterogeneous nitrogen-doped carbon (N-C) support, inspired by routes for metalation of molecular macrocyclic iron complexes. The N-C support, derived from pyrolysis of a ZIF-8 metal-organic framework, is metalated via solution-phase reaction with FeCl2 and tributyl amine, as a Brønsted base, at 150 °C. Fe active sites are characterized by 57Fe Mössbauer spectroscopy and aberration-corrected scanning transmission electron microscopy. The site density can be increased by selective removal of Zn2+ ions from the N-C support prior to metalation, resembling the transmetalation strategy commonly employed for the preparation of molecular Fe-macrocycles. The utility of this approach is validated by the higher catalytic rates (per total Fe) of these materials relative to established Fe-N-C catalysts, benchmarked using an aerobic oxidation reaction.

Prevalence and Risk Factors of Discordance Between Hip and Spinal Bone Mineral Density Among Saudi Subjects.

Background Discordance between hip and spine on dual-energy x-ray absorptiometry is a well-known problem in diagnosing osteoporosis. The prevalence and risk factors of this problem have not been studied in the Saudi population. The objective of this study was to document this discordance in our population and its possible risk factors. Materials and methods We analyzed data obtained from subjects who had dual x-ray absorptiometry (DXA) between January 2021 and December 2021 at King Khalid University Hospital, Riyadh, Saudi Arabia. Subjects with the following conditions were excluded: secondary osteoporosis, patients taking anti-osteoporotic agents, patients on steroids or hormonal replacement therapy, hyperparathyroidism, hypoparathyroidism, and chronic renal disease. A total of 1388 patients satisfied our inclusion criteria. World Health Organization (WHO) criteria for diagnosis were implemented. Major discordance was defined as osteoporosis in one site and normal in the other. Minor discordance was defined as a difference of no more than one World Health Organization diagnostic class between two sites. Bivariate statistical analysis was achieved using appropriate statistical tests (chi-square, student's t-test, one-way analysis of variance, and Pearson's correlation), based on the type of study and outcome variables. A p-value of < 0.05 and 95% CI were used to report the statistical significance and precision of results. Results A total of 1388 subjects were analyzed, of which, 1196 (86%) were females with a mean age of 58.8 (13.8 SD) and 192 were males with a mean age of 58 (18.0 SD). Lumbar osteoporosis was found in 312 (22.5%) participants while hip osteoporosis was reported in 73 (5.3%) of the participants. Major discordance was documented in 85 (6.1%) of all participants (6.3% of the male and 6.1% of the female patients). All of these subjects had lumbar spine osteoporosis with normal hip bone mineral density (BMD). Minor discordance was found in 591 patients (42.6%). Obesity (BMI > 30) was found to be a risk factor for both major (2.10-11.6, 95% CI) and minor (2.5-11.4, 95% CI) discordance. Conclusion Discordance between hip and spine BMD is common among Saudi subjects. Lumbar spine osteoporosis with normal hip BMD caused this discordance in our subjects. Obesity could be responsible for the occurrence of this discordance. Mechanisms may include higher rate of turnover in spine, technical artifacts in the measurements of lumbar spine BMD, or due to the effects of weight loading. Caution should be exercised when interpreting DXA results, especially in obese subjects.
