RESUMO

Malignant transformation of fibrous dysplasia lesions has been reported in patients with fibrous dysplasia/McCune-Albright syndrome (FD/MAS). Recently, we have observed an increased risk for breast cancer. In this study, the prevalence of skeletal and extraskeletal malignancies in patients with FD/MAS in the Netherlands was assessed by analyzing data from our cohort of FD/MAS patients, the Dutch Pathology Registry (PALGA), and the Netherlands Cancer Registry (NCR). We extracted data on sex, age at diagnosis of FD/MAS, type of FD/MAS, type of malignancy, and age at diagnosis of malignancy and histology of bone and malignant tissue when available, including GNAS-mutation analysis from patients' medical records. Standardized Morbidity Ratios (SMRs) with 95% confidence intervals were calculated. Twelve malignancies were identified in the LUMC FD/MAS cohort and 100 in the PALGA cohort. In this cohort, SMR was increased for osteosarcoma (19.7, 95% CI 3.5-48.9), cervical cancer (4.93, 95%CI 1.7-8.2), thyroid cancer (3.71, 95% CI 1.1-7.8), prostate cancer (3.08, 95% CI 1.8-4.6), and melanoma (2.01, 95%CI 1.2-3.1). SMRs for pancreatic cancer or hepatocellular carcinoma could not be calculated due to low numbers. The small number of malignancies identified in our FD/MAS cohort precluded the calculation of SMRs for our cohort specifically. Our findings show that patients with FD/MAS appear to have an increased risk for osteosarcoma, cervical, thyroid, and prostate cancer and melanoma. However, these data should be interpreted with caution, as true incidence rates of the identified malignancies may be influenced by the inclusion of only patients with histologically confirmed FD/MAS. The etiology of this increased risk for malignancies still needs to be elucidated.

RESUMO

PURPOSE: To determine the burden of illness in patients with not adequately controlled chronic hypoparathyroidism receiving conventional therapy in Belgium and the Netherlands. METHODS: Data were generated from a cross-sectional, two-part online survey where endocrinologists from both countries and nephrologists from Belgium were invited by phone to participate. Part 1 included collecting data on general management of patients with hypoparathyroidism. In Part 2, physicians were requested to provide data on one or two current cases of patients with chronic hypoparathyroidism not adequately controlled on conventional therapy. Data collected included aetiology of hypoparathyroidism, clinical manifestations, comorbidities, results of laboratory and other investigations used for diagnosis and screening for complications, therapy received, and physician's perception of impaired quality of life (QoL). RESULTS: Thirty-six endocrinologists and 29 nephrologists from Belgium and 28 endocrinologists from the Netherlands participated in the survey. Data included clinical symptoms, biochemical parameters, and QoL for 97 current patients with not adequately controlled chronic hypoparathyroidism on conventional therapy. Median duration of not adequately controlled hypoparathyroidism was 2.2 years, range 0.17-20.0. Most patients had neuromuscular (85%) and/or neurological (67%) symptoms, 71% had abnormal biochemical parameters, 10% were overweight, and physicians perceived that 71% had impaired QoL. Most frequently reported comorbidities included hypertension (25%), renal comorbidity (20%), diabetes mellitus (12%), and dyslipidaemia (11%). CONCLUSION: Patients with chronic hypoparathyroidism not adequately controlled on conventional therapy experience a substantial burden of illness, mainly due to persistence of symptoms and presence of multiple comorbidities.

RESUMO

BACKGROUND: Systemic lupus erythematosus (SLE) patients have lower bone mineral density (BMD) compared with healthy individuals because of general, genetic, disease and medication-related factors. The disturbance of the receptor activator of nuclear factor-κB ligand (RANKL)/osteoprotegerin (OPG) ratio has been reported to be associated with low BMD in many disorders in adults and children alike. OBJECTIVES: The objectives of this study were (i) to assess serum OPG, RANKL and RANKL/OPG ratio levels in SLE children and controls, (ii) to determine whether the cumulative glucocorticoid (CGCS) dose had any effect on the concentration of serum RANKL, OPG and RANKL/OPG ratio, and (iii) to determine the relation of these parameters to BMD. METHODS: We evaluated 50 SLE children and 50 age- and sex-matched healthy controls. RANKL and OPG were assessed in serum and compared between patients and controls. For SLE patients, a univariate followed by multivariable analysis were carried out to detect the possible predictors of the changes in RANKL, OPG and RANKL/OPG ratio levels. Lumbar BMD for all patients was assessed by dual-energy X-ray absorptiometry (DXA) scan and then correlated to different probable correlated factors. RESULTS: RANKL, OPG and RANKL/OPG ratio were significantly higher in SLE patients (p ≤ 0.001). Univariate analysis showed significant correlations of RANKL with CGCS (p ≤ 0.001) and with DXA scan z-score (p = 0.007): OPG was significantly correlated to Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) score (p = 0.001) and anti-double-stranded DNA (p = 0.001), whereas RANKL/OPG was significantly correlated to duration of illness and DXA z-score (p = 0.002). The multivariable analysis showed that DXA z-score was an independent predictor of RANKL and RANKL/OPG ratio (p = 0.019 and 0.008, respectively), whereas SLEDAI score was an independent predictor of OPG levels. BMD was negatively correlated to disease duration (p = 0.008) and CGCS dose (p = 0.015), but no significant correlation has been found between BMD and cumulative SLEDAI score (p = 0.29). CONCLUSIONS: Serum RANKL/OPG ratio is elevated in Egyptian children with SLE and is considered a risk factor for reduced bone mass in these children. Other risk factors for low BMD include high CGCS dose and disease duration, supporting that osteoporosis in SLE is multifactorial.

RESUMO

Fibrous dysplasia (FD) is a rare bone disorder in which normal bone is replaced by fibrous tissue resulting in pain, deformities, pathological fractures or asymptomatic disease. Illness perceptions are patients' cognitions and emotions about their illness and its treatment, which may impact on Quality of Life (QoL). Here, we explore illness perceptions in patients with FD compared to other disorders, identify factors associated with illness perceptions and evaluate their relationship with QoL. Ninety-seven out of 138 eligible patients from the LUMC FD cohort completed the Illness Perception Questionnaire-Revised (IPQ-R) and the Short Form-36 (SF-36). Age, Gender, Skeletal Burden Score (SBS), FGF-23 levels, type of FD and SF-36 scores were analysed for an association with illness perceptions. We observed significant (p < 0.01) differences in patients' illness perceptions between FD subtypes in the domains: identity, timeline acute/chronic and consequences. Patients with craniofacial FD reported to perceive more consequences (p = 0.022). High SBS was associated with perceiving more negative consequences and attributing the cause of FD to psychological factors (p < 0.01), and high FGF-23 levels with attributing more symptoms to the disease and perceiving more consequences (p < 0.01). The IPQ-R domain identity, timeline acute/chronic, timeline cyclical, consequences, emotional representations and treatment control were significantly associated with impairments in QoL. Illness perceptions in patients with FD relate to QoL, differ from those in patients with other disorders, and are associated with disease severity. Identifying and addressing maladaptive illness perceptions may improve quality of life in patients with FD.

RESUMO

Impairments in quality of life (QoL) have been reported in patients with fibrous dysplasia (FD). Here, we examine coping strategies in FD and assess whether these coping strategies are associated with QoL and disease severity. Ninety-two patients (66% females) filled out the Utrecht Coping List (UCL), Short Form-36, and the Brief Pain Inventory (BPI). Coping strategies of patients with FD were compared with reference data from a random sample of Dutch women and patients with chronic pain. Compared to healthy adults, patients expressed more emotions (p < 0.01). Compared to patients with chronic pain, patients with FD used more active coping strategies (p < 0.001), and sought more distraction (p = 0.01) and more social support (p < 0.001). Using more passive coping strategies was associated with more impairment in social function, physical role, mental health, vitality (all p < 0.001), and general health (p < 0.01). Using more avoidant coping strategies was associated with worse mental health and less vitality (both p < 0.01). More expression of emotions was associated with worse mental health (p < 0.01). Type and clinical severity of FD were not associated with coping behavior. Patients with FD have different coping strategies compared to random Dutch reference populations with or without pain. In FD, using more passive coping strategies was associated with more impairment in several aspects of QoL. There was no relationship between coping behavior and clinical characteristics, pointing to biomedical variables not determining the way patients cope with their illness. Recognition of less effective coping strategies can be helpful in the understanding and adaptation of these coping strategies, improving personalized clinical care, with the ultimate goal to improve QoL in patients with FD.

RESUMO

We evaluated the relationship between bone material strength index (BMSi) and fragility fractures, including vertebral fractures. Our data showed that BMSi is low in all fracture patients with low bone mass, independently of whether patients sustained a vertebral or a non-vertebral fracture. INTRODUCTION: Impact microindentation (IMI) is a new technique for the measurement of tissue level properties of cortical bone in vivo. Previous studies showed an association between BMSi and non-vertebral fractures, but an association with vertebral fractures is still being debated. The objective of this paper was to evaluate the relationship between BMSi and different types of fragility fractures, including vertebral fractures. METHODS: In this cross-sectional study, we measured BMSi in patients of both sexes with different types of fragility fractures and low bone mass with the IMI method using the Osteoprobe®. Vertebral fractures were diagnosed and graded on lateral spine radiographs. RESULTS: A total of 132 patients were included in the study, of whom 101 patients (65 women) had sustained a low energy fracture and 31 (mean age 57.7 ± 9.9 years) had no history or radiological evidence for a fracture. Of the fracture patients, 53 (mean age 62.8 ± 8.3 years) had only non-vertebral fractures (VF-/Fx+), 34 (mean age 62.8 ± 9.9 years) had vertebral and non-vertebral fractures (VF+/Fx+), and 14 (mean age 64.7 ± 9.3 years) had only vertebral fractures (VF+/Fx-). BMSi values, adjusted for age and BMD, were similar for all three groups of fracture patients (78.9 ± 0.7, 78.3 ± 0.9, and 78.4 ± 1.4, respectively; p = 0.866). BMSi values were not associated with number or severity of vertebral fractures. CONCLUSION: Our data demonstrate that BMSi is low in fracture patients with low bone mass, irrespective of whether they sustained a vertebral fracture or a non-vertebral fracture.

RESUMO

We evaluated the value of VFA in the identification of vertebral fractures using a retrospective study and a meta-analysis. Performance of VFA was adequate in the meta-analysis although this was not demonstrated in our centre. We recommend checking the performance of VFA tools before exclusively relying on this tool. INTRODUCTION: Vertebral fractures are traditionally diagnosed using conventional radiographs of the spine. Vertebral fracture assessment (VFA) has been advocated as an alternative tool in the diagnosis of these fractures. METHODS: We conducted a retrospective study as well as a systematic review and a meta-analysis to evaluate the performance of VFA compared to conventional spinal radiography in patients who had sustained a fracture and thus at risk for osteoporosis. A risk of bias analysis was also performed. RESULTS: The diagnostic study included 542 patients (25% male) with fractures. The sensitivity of low-radiation VFA to detect a patient with a vertebral fracture ≥ Genant grade 2 was 0.77 and its specificity 0.80. Two hundred ninety-seven (55%) patients had ≥1 and 135(25%) ≥3 unevaluable vertebrae. The systematic review identified 16 studies including a total of 3238 subjects (19% male) with a mean age range of 45 to 74 years. Seven studies had a low risk of bias and 9 had an intermediate risk, mainly due to not consecutively including patients. The pooled sensitivity of VFA to detect a patient with a vertebral fracture ≥Genant grade 2 was 0.84 (95% CI, 0.72-0.92) and specificity 0.90 (95% CI, 0.84-0.94). CONCLUSIONS: Our findings from the meta-analysis suggest an adequate performance of VFA for the detection of vertebral fractures. However, we could not demonstrate these findings in our center, especially the specificity. Our data advocate caution with exclusively relying on VFA in the assessment of vertebral fractures without identifying performance and potential limitations of the technique.

RESUMO

BACKGROUND: Improving prediction of treatment outcomes in chronic hepatitis C (CHC) genotype 4 (G4) is necessary to increase sustained viral response (SVR) rates. Vitamin D related and interferon stimulated genes are good candidates as they are recently crosstalk altering interferon response. Thus single nucleotide polymorphisms (SNPs) within some of these genes and multiple stepwise regression analysis including other independent predictors (IL28B(rs12979860), serum 25OH-vitamin D, serum alfa-fetoprotein (AFP)) were performed on a cohort of 200 Egyptian CHC patients treated with Pegylated interferon-alpha (Peg-IFN) plus ribavirin. METHODS: SNPs in cytochrome P-450 (CYP2R1)(rs10741657AG), vitamin D receptor (VDR)(rs2228570AG, rs1544410CT), oligoadenylate synthetases-like (OASL)(rs1169279CT) and adenosine deaminases acting on RNA (ADAR)(rs1127309TC) genes were analyzed by real-time PCR. RESULTS: The carrier state of A allele in VDR rs2228570 and CYP2R1 rs10741657 genes were independently associated with SVR [OR 6.453 & 3.536, p < 0.01 respectively]. Combining carriers of A allele in CYP2R1 and VDR genes with IL28B C/C genotype increased the probability of SVR from 80 % to reach 87.8 %, 93 % and 100 %. No relation was found between VDR rs1544410CT, ADAR rs1127309TC, OASL rs1169279CT polymorphisms and treatment outcome. Combining VDR rs2228570 A/A genotype with IL28B C/C genotype increased the probability of SVR from 82 % to reach 100 % and from 29 % to reach 80 % in C/T+ T/T IL28B genotype in none F4 liver disease patients. CONCLUSION: Vitamin D related (VDR rs2228570 and CYP2R1 rs10741657) and IL28B rs12979860 genes polymorphisms accurately assure SVR in naïve CHC G4 patients treated with low cost standard therapy.

RESUMO

BACKGROUND: Infections downregulate cytochrome-P activities and thus may alter drug disposition, especially for drugs with a narrow therapeutic index. Cyclosporine (CyA), still used for the prevention of allograft rejection in renal transplant recipients in Egypt, seems to be affected by these infectious changes, based on random clinical observations. In the present study, the effects of bacterial and fungal infection on CyA metabolism were studied in renal transplant patients and subsequent nephrotoxicity was monitored. METHODS: Twenty renal transplant patients, diagnosed with fungal or bacterial infection, were recruited from the renal transplantation outpatient clinic in Alexandria University Hospitals. No dose adjustment in CyA was performed at least 1 week before the onset of infection. Exclusion criteria were patients with acute or chronic unstable liver disease, elderly patients, and patients on concomitant drugs affecting CyA metabolism. CyA trough levels and serum creatinine (SCR) concentrations were measured by fluorescence polarization immunoassay and enzymatic assay, respectively, pre-infection, during infection and in many cases, post infection. RESULTS: CyA trough levels and SCR concentrations increased significantly during the infection (P < 0.001, P = 0.002) respectively. Of the patients, 87% experienced a concomitant rise in CyA trough level and SCR concentrations. No significant difference between pre-infection and post-infection levels of CyA trough and SCR was found. CONCLUSIONS: CyA trough and SCR levels increased during bacterial and fungal infections and returned to pre-infection levels once the infection was resolved. The data generated stress the importance of monitoring CyA levels during episodes of infection. Our recommendations concerning CyA dose adjustment differ according to severity and duration of infection.

RESUMO

BACKGROUND: The role of zoledronic acid (ZA) when added to the neoadjuvant treatment of breast cancer (BC) in enhancing the clinical and pathological response of tumors is unclear. The effect of ZA on the antitumor effect of neoadjuvant chemotherapy has not prospectively been studied before. PATIENTS AND METHODS: NEOZOTAC is a national, multicenter, randomized study comparing the efficacy of TAC (docetaxel, adriamycin and cyclophosphamide i.v.) followed by granulocyte colony-stimulating factor on day 2 with or without ZA 4 mg i.v. q 3 weeks inpatients withstage II/III, HER2-negative BC. We present data on the pathological complete response (pCR in breast and axilla), on clinical response using MRI, and toxicity. Post hoc subgroup analyses were undertaken to address the predictive value of menopausal status. RESULTS: Addition of ZA to chemotherapy did not improve pCR rates (13.2% for TAC+ZA versus 13.3% for TAC). Postmenopausal women (N = 96) had a numerical benefit from ZA treatment (pCR 14.0% for TAC+ZA versus 8.7% for TAC, P = 0.42). Clinical objective response did not differ between treatment arms (72.9% versus 73.7%). There was no difference in grade III/IV toxicity between treatment arms. CONCLUSIONS: Addition of ZA to neoadjuvant chemotherapy did not improve pathological or clinical response to chemotherapy. Further investigations are warranted in postmenopausal women with BC, since this subgroup might benefit from ZA treatment.

RESUMO

Pain is a significant health issue, and pain assessment is essential for proper diagnosis, follow-up, and effective management of pain. The conventional methods of pain assessment often suffer from subjectivity and variability. The main issue is to understand better how people experience pain. In recent years, artificial intelligence (AI) has been playing a growing role in improving clinical diagnosis and decision-making. The application of AI offers promising opportunities to improve the accuracy and efficiency of pain assessment. This review article provides an overview of the current state of AI in pain assessment and explores its potential for improving accuracy, efficiency, and personalized care. By examining the existing literature, research gaps, and future directions, this article aims to guide further advancements in the field of pain management. An online database search was conducted via multiple websites to identify the relevant articles. The inclusion criteria were English articles published between January 2014 and January 2024). Articles that were available as full text clinical trials, observational studies, review articles, systemic reviews, and meta-analyses were included in this review. The exclusion criteria were articles that were not in the English language, not available as free full text, those involving pediatric patients, case reports, and editorials. A total of (47) articles were included in this review. In conclusion, the application of AI in pain management could present promising solutions for pain assessment. AI can potentially increase the accuracy, precision, and efficiency of objective pain assessment.

RESUMO

BACKGROUND: Testicular cancer patients have an increased risk for cardiovascular disease (CVD), which might be related to the increased prevalence of the metabolic syndrome (MetS) in this group of patients. METHODS: We assessed the prevalence of MetS and calculated the 10-year CVD risk in a cohort of 255 testicular germ cell tumour survivors (median age, 38.7 years; interquartile range, 31-48) at a mean of 7.8 years after anti-cancer treatment, and compared these with data obtained from 360 healthy men. RESULTS: Survivors had an age-adjusted increased risk for MetS of 1.9 compared with that of healthy controls. The risk for MetS was highest in survivors treated with combination chemotherapy (CT) 2.3 (Adult Treatment Panel of the National Cholesterol Education Program classification) and 2.2 (International Diabetes Federation classification). The risk of MetS was especially increased in survivors with testosterone levels in the lowest quartile (OR, 2.5). Ten-year cardiovascular risk as assessed by the Framingham Risk Score (3.0%) and Systemic Coronary Risk Evaluation (1.7%) algorithms was low, independent of treatment, and was comparable to controls. CONCLUSION: Testicular germ cell tumour survivors have an increased prevalence of MetS, with hypogonadism and CT treatment being clear risk factors for the development of the syndrome. The increased prevalence of MetS was not associated with an increased 10-year cardiovascular risk.

RESUMO

UNLABELLED: We addressed the question whether the response of osteoporotic patients to bisphosphonate treatment is reduced with time. Bisphosphonate-treated women with postmenopausal or glucocorticoid-induced osteoporosis showed adequate and consistent changes of bone markers to subsequently administered intravenous pamidronate. Response of osteoporotic patients to bisphosphonates is not impaired during their long-term administration. INTRODUCTION: Inadequate response to bisphosphonate treatment has been described in patients with Paget's disease of bone but has not been addressed in osteoporosis although treatment failure is a clinically relevant problem. METHODS: Twenty one women with postmenopausal osteoporosis (PMO) aged 68 ± 8.2 years and 14 women with glucocorticoid-induced osteoporosis (GIOP) aged 65 ± 10 years were treated with tri-monthly intravenous infusions of 45 mg of pamidronate for 1 year. All patients had been previously treated with bisphosphonates (alendronate, risedronate, pamidronate) for a mean period of 6.2 years (range, 1.3-14 years). Blood samples were taken for measurement of the bone resorption marker C-terminal crosslinking telopeptide of type I collagen (CTX-I) on days 1 and 4 and of the bone formation marker procollagen type I N propeptide, (P1NP) on day 1 of every tri-monthly treatment course. RESULTS: With each treatment course there was a significant decrease in serum CTX-I on day 4 and an increase to baseline values 3 months after each infusion in both PMO (mean values, day 1: 291.33 ± 160.78 pg/ml vs. day 4: 131 ± 91.7 pg/ml, p < 0.001) and GIOP (day 1: 219.3 ± 114.8 pg/ml vs. day 4: 98.8 ± 51.6 pg/ml, p < 0.001). Serum P1NP remained stable during the whole year of treatment. CONCLUSIONS: Long-term bisphosphonate treatment of women with either PMO or GIOP does not impair the response to subsequently administered intravenous pamidronate suggesting that inadequate response to long-term bisphosphonate treatment is not responsible for treatment failure.

RESUMO

The knowledge of the prevalence of spinal cord disorders (SCD) is important to understand specific causes in each part of the worldand to allow to potentially adapt health care and public policy including law enforcement to the main causes. SCD have important personal, biopsychological, socio-economic, short-term and long-term consequences. An SCD is the underlying cause for 1 of every 40 patients admitted to a major trauma centre. The affected population consists primarily of young male adults. The aim of the present study was to determine the prevalence and cause of SCD in Al-Quseir City, using a door-to-door method. The total of inhabitants was 33,285 in Al-Quseir City screened by 3 specialists of neurology. Suspected cases were subjected to full clinical assessment and MRI or CT of the spine. The prevalence rate of SCD was 63/100,000 for the total population. Traumatic spinal cord injury had a prevalence of 18/100,000, while non-traumatic SCD was found in 45/100,000. Degenerative cervical disc prolapse was the most common aetiology of SCD with a prevalence rate of 27/100,000.

RESUMO

Strontium ranelate has been available as an osteoporosis treatment in Europe since 2004. This article describes a large European observational survey of the use of strontium ranelate in clinical daily practice. A retrospective observational registry included 32,446 women consulting for postmenopausal osteoporosis in seven countries. Within the registry, 12,046 women were receiving strontium ranelate and were followed up over 3 years. The baseline characteristics of the follow-up cohort were similar to those of the whole registry cohort (age, 68.9 ± 10.3 years; body mass index, 25.6 ± 4.3 kg/m(2); lumbar spine T-score, -2.57 ± 0.85 SD; femoral neck T-score, -2.11 ± 0.86 SD). At baseline, 77 % of patients had at least one risk factor for osteoporosis, and 46 % had a previous history of osteoporotic fracture. Mean duration of follow-up was 32.0 ± 9.7 months, and treatment duration was 25.2 ± 13.7 months (24,956 patient-years of treatment). Persistence with strontium ranelate was 80 % at 1 year, 68 % at 2 years, and 64 % at 32 months; most patients (about 80 %) reported rarely omitting a dose. At least one emergent adverse event was reported in 2,674 (22 %) patients, most frequently gastrointestinal side effects. The crude incidence of venous thromboembolic events was 2.1/1,000 patient-years. No cases of hypersensitivity reactions, such as drug rash with eosinophilia and systemic symptoms (DRESS), Steven-Johnson syndrome, or toxic epidermal necrolysis, were reported. During follow-up, a fracture occurred in 890 patients (7 %); 429 of the fractures were nonvertebral fractures. Our observational survey over 32 months indicated good rates of adherence with strontium ranelate and confirmed its good safety profile in the management of postmenopausal osteoporosis.

RESUMO

Non-metastatic prostate cancer (PCa) patients are at increased risk for osteoporosis and fractures mainly due to androgen deprivation therapy (ADT)-associated hypogonadism, but this remains largely underdiagnosed and untreated. In this study, we examine the value of pre-screening calcaneal QUS in identifying patients who should be referred for screening for osteoporosis using dual-energy X-Ray absorptiometry (DXA). In a single-center retrospective cross-sectional cohort study, we analysed data on DXA and calcaneal QUS measurements systematically collected between 2011 and 2013 in all non-metastatic PCa patients attending our Uro-Oncological Clinic at the Leiden University Medical Center. Receiver operating characteristic curves were used to assess the positive (PPV) and negative (NPV) predictive values of QUS T-scores of 0, -1.0, and - 1.8 in identifying DXA-diagnosed osteoporosis (T-scores ≤ - 2.5 and ≤ -2) at lumbar spine and/or femoral neck. Complete sets of data were available in 256 patients, median age 70.9 (53.6-89.5) years; 93.0 % had received local treatment, 84.4 % with additional ADT. Prevalence of osteoporosis and osteopenia was respectively 10.5 % and 53 %. Mean QUS T-score was -0.54 ± 1.58. Whereas PPV at any QUS T-score was <25 %, precluding the use of QUS as surrogate for DXA in screening for osteoporosis, QUS T-scores of -1.0 to 0.0 had a NPV of ≥94.5 % for DXA T-scores ≤ 2.5 and ≤ -2 at any site, confidently identifying patients least likely to have osteoporosis, thereby significantly reducing the number of patients requiring DXA screening for diagnosing osteoporosis by up to two-third. Osteoporosis screening is a significant unmet need in non-metastatic prostate cancer patients treated with ADT, and QUS may represent a valuable alternative pre-screening strategy to overcome logistics, time demands, and economic barriers encountered with current strategies for osteoporosis screening in these patients. Summary: Osteoporosis and associated increased fracture risk are common in non-metastatic prostate carcinoma, mainly due to androgen deprivation therapy, but these often remain underdiagnosed and untreated. We demonstrate that QUS is a safe, less costly pre-screen tool that reduces by up to two-third the number of patients requiring referral for DXA for osteoporosis screening.

RESUMO

BACKGROUND: With aging, there is a parallel increase in the prevalence of dementia worldwide. The aim of this work is to determine the prevalence of dementia among the population of Al Kharga District, New Valley, Egypt. METHODS: Screening of all subjects aged ≥50 years (n = 8,173 out of 62,583 inhabitants) was done through a door-to-door survey by 3 neurologists, using a short standardized Arabic screening test and a modified Mini-Mental State Examination. Suspected cases were subjected to full clinical examination, psychometric assessment using the Cognitive Abilities Screening Instrument, Instrumental Activities of Daily Living Scale, Geriatric Depression Scale, Hachinski Ischemic Score, DSM-IV-TR diagnostic criteria, neuroimaging, and laboratory investigations, when indicated. RESULTS: The prevalence rate of dementia was 2.26% for the population aged ≥50 years. It increased steeply with age to a maximum of 18.48% for those aged ≥80 years. Alzheimer's disease (51.2%) was the most common subtype, followed by vascular dementia (28.7%), dementia due to general medical conditions (12.8%), and lastly dementia due to multiple etiologies (7.3%). Mild dementia was the commonest (53.7%). CONCLUSION: Dementia is prevalent in Egypt as elsewhere. Detection through a door-to-door survey is the best method in developing countries for early detection of mild cases.

RESUMO

AIMS: Omentin-1 and chemerin have been identified as interesting novel adipokines that may modulate insulin action. Also, they have been suggested to be linked to obesity-induced insulin resistance. The aim of this study was to analyse the relationship between these adipokines and interleukin-6, insulin resistance and anthropometric and metabolic variables in patients with Type 2 diabetes mellitus and in patients with Type 2 diabetes who have ischaemic heart disease. METHODS: Seventy-five individuals with Type 2 diabetes and 15 healthy control subjects were enrolled in this study. Insulin levels, interleukin-6, omentin-1 and chemerin were measured by ELISA. RESULTS: Serum omentin-1 levels were found to be significantly decreased in patients with Type 2 diabetes (19.7 ± 1 ng/ml) and in patients with Type 2 diabetes with ischaemic heart disease (18.5 ± 1.6 ng/ml) compared with healthy control subjects (27.4 ± 2.6 ng/ml) at P < 0.01. Moreover, serum chemerin levels were found to be significantly increased in patients with Type 2 diabetes (347 ± 14 ng/ml) and in patients with Type 2 diabetes with ischaemic heart disease (341 ± 16.5 ng/ml) compared with healthy control subjects (281 ± 13 ng/ml) at P < 0.01. Interestingly, omentin-1 and chemerin levels were found to be significantly correlated negatively with each other as well as being individually correlated with some selected anthropometric, biochemical and clinical variables. In conclusion, both omentin-1 and chemerin might play as a pivotal role in obesity and its associated disorders as Type 2 diabetes; however, their role in cardiovascular diseases needs to be fully elucidated.

RESUMO

AIM: Adipose tissue is now regarded as a source of proinflammatory mediators which may contribute to vascular injury, insulin resistance (IR), and atherogenesis, however, some of them have a protective role against vascular inflammation and/or IR; namely adiponectin and nitric oxide (NO). Adiponectin is a fat derived hormone, which enhances insulin sensitivity. In experimental studies adiponectin was shown to have anti-atherogenic properties by suppressing endothelial expression of adhesion molecules as endothelial-selectin (E-selectin) and inflammatory cytokines as high-sensitivity C-reactive protein (hsCRP), interleukin-1ß (IL-1ß), and monocyte chemotactic protein-1 (MCP-1). Therefore, the aim of the study was to evaluate plasma adiponectin, E-selectin, hsCRP, IL-1ß, and MCP-1 concentrations in obese patients with and without coronary heart disease (CHD) having type 2 diabetes mellitus (DM) and evaluation of their relationship with selected anthropometric, biochemical, and clinical parameters. METHODS: The study group consisted of (N.=70) males, 20 of which served as healthy non-obese controls (group I) (mean age 38.5±3.7 years; mean BMI 28±1.2 kg/m2). Patients enrolled in the study were classified into the following groups: type 2 DM obese subjects without CHD (group II) (N.=25) (mean age 42.2±3 years; mean BMI 32.1±1.4 kg/m2) and type 2 DM obese subjects with CHD (group III) (N.=25) (mean age 40.6±3 years; mean BMI 31.5±1.2 kg/m2). Glucose and insulin estimation was performed and insulin resistance index (HOMA-IR) was calculated. In the fasting state, the plasma HbA1c, adiponectin, E-selectin, in comparison to hsCRP, IL-1ß, MCP-1, and lipid parameters were estimated. RESULTS: FBG, HbA 1c %, lipids, insulin, MDA, NO, hsCRP, IL-?, MCP-1, Adiponectin as well as E-selectin concentration were significantly different in patients with type 2 DM and CHD in comparison to patients without CHD and moreover, the healthy control group (P=0.01). There was a significant negative correlation between adiponectin and E-selectin (r=-0.642; P=0.0001). CONCLUSION: Our study supports the hypothesis that decreased level of adipokine(s), together with increased oxidative stress, pro-inflammatory marker(s) as well as endothelial adhesion molecule(s) contributes to the complex process of atherosclerosis in type 2 diabetic obese patients that may lead eventually to CHD.

RESUMO

PURPOSE: Validated diagnostic scales for dementia in Arabic are still scarce. The aim of this study is to construct a standardized dementia scale for dementia diagnosis among the Arabic-speaking population. PATIENTS AND METHODS: Construction of the Dementia Arabic Scale (DAS) was done, followed by evaluation of content validity. A pilot study was done to ascertain feasibility and language clarity used in the scale. Patients diagnosed to have major neurocognitive disorder according to DSM-V criteria and control group were subjected to DAS, mini-mental state examination (MMSE) and Cognitive Abilities Screening Instrument (CASI). Finally, standardization of the scale and estimation of cutoff point, sensitivity, specificity, positive predictive value and negative predictive value of the newly constructed scale (DAS) were done. RESULTS: There is significant correlation between DAS and both MMSE and CASI on Pearson's correlation study. The internal consistency of the DAS scale was good, with Cronbach's alpha correlation coefficient of 0.88. At cut-off ≤95 for literate, and ≤68 for illiterate, the sensitivity of the DAS scale was 100%, 87% for literate and illiterate, respectively, while specificity was 84%, 96% respectively, with an area under the receiver operating characteristic curve of (AUC) 0.96. CONCLUSION: The DAS scale is an acceptable, reliable and valid scale for the diagnosis of dementia in Arabic-speaking countries.
