RESUMEN

BACKGROUND: Falling on stairs is a major health hazard for older people. Risk factors for stair falls have been identified, but these are mostly examined in controlled biomechanics/gait laboratory environments, on experimental stairs with a given set of step dimensions. It remains unknown whether the conclusions drawn from these controlled environments would apply to the negotiation of other domestic staircases with different dimensions in real houses where people live. OBJECTIVES: The aim of this paper is to investigate whether selected biomechanical stepping behavior determined through stair gait parameters such as foot clearance, foot contact length and cadence are maintained when the staircase dimensions are different in real houses. METHODS: Twenty-five older adults (>65 years) walked on a custom-made seven-step laboratory staircase. Older adults were classified into two groups (fallers and non-fallers) based on recent fall history. Among the 25 participants, 13 people had at least one fall, trip, or slip in the last six months and they were assigned to the fallers group; 12 people did not experience any fall in the last six months, so they were assigned to the non-fallers group. In addition, these participants walked on the stairs in three different real exemplar houses wearing a novel instrumented shoe sensor system that could measure the above stair gait parameters. MATLAB was used to extract fall risk parameters from the collected data. One-way ANOVA was used to compare fall risk parameters on the different staircases. In addition, the laboratory-based fall risk parameters were compared to those derived from the real house stairs. RESULTS: There was a significant difference in selected stair-fall biomechanical risk factors among the house and laboratory staircases. The fall risk group comparisons suggest that high-risk fallers implemented a biomechanically riskier strategy that could increase overall falling risk. CONCLUSIONS: The significant differences due to the main effects of the fallers and non-fallers groups were obtained. For example, when ascending, the fallers group had less foot clearance on the entry (p = 0.016) and middle steps (p = 0.003); in addition, they had more foot clearance variability on the entry steps (p = 0.003). This suggests that the fallers group in this present study did not adopt more conservative stepping strategies during stair ascent compared to low-risk older adults. By showing less foot clearance and more variability in foot clearance, the risk for a trip would be increased.

RESUMEN

Introduction: Despite limited evidence about the efficacy and safety of dietary supplements (DSs) for improving mental health, people with or without mental disorders often tend to use them, especially during the ongoing COVID-19 pandemic. Previous studies focused on DS use for maintaining or improving overall health; Therefore, this study aimed to assess the prevalence of DSs for mental health among the SA population and to determine the factors that affect their use. Methods: This cross-sectional study was based on an online survey of Saudi Arabian participants between July and August 2021 with an anonymous, self-completed questionnaire distributed using convenience sampling. The questionnaire included queries related to demographic information, DS use assessment, and mental health evaluation using the Patient Health Questionnaire (PHQ-9), the Generalized Anxiety Disorder 7-item (GAD-7), questionnaire, and the Insomnia Severity Index (ISI). Results: In total, 443 participants from various regions of Saudi Arabia completed the questionnaire. The prevalence of DS use in the Saudi population was 44%. Vitamin D (28%) and melatonin (20%) were the most commonly reported DSs used for mental health. The odds of DS use were three times higher in responders with previous mental health diagnoses (OR: 2.972; 95% CI: 1.602-5.515). Furthermore, the chances of using DSs almost doubled in patients with sub-threshold and moderate to severe insomnia (OR: 1.930; 95% CI: 1.191-3.126 and OR: 2.485; 95% CI: 1.247-4.954, respectively). Conclusion: Responders diagnosed by a specialist with psychiatric disorders or current insomnia had a higher chance of using DSs. Thus, healthcare providers must provide evidence-based information regarding DSs for mental health improvement and encourage the public to consult healthcare professionals before self-medicating for mental health problems.

RESUMEN

Background: Extensively drug resistant tuberculosis (XDR-TB) is considered as a major threat to global health. This study aimed to analyse the treatment outcomes and identify the factors significantly associated with unfavourable treatment outcomes among XDR-TB patients. Methods: We conducted a retrospective observational study at 10 Programmatic Management Units of the National Tuberculosis Control Program of Pakistan. The Electronic Nominal Recording Reporting System records were used to collect data of all eligible XDR-TB patients registered at the study sites between March 2012 and August 2018. Treatment outcomes were analysed as per the standard criteria. Factors associated with unfavourable treatment outcomes were analysed by using multivariate binary logistic regression analysis. Results: Out of the total 184 patients, 59 (32.1%) completed their treatment successfully. Whereby, 83 patients (45.1%) died, 24 (13%) had treatment failure, and 11 (6%) were lost to follow-up. Treatment outcomes were not evaluated in 7 (3.8%) patients. Factors significantly associated with unfavourable treatment outcomes included; conventional therapy with bedaquiline, unfavourable interim treatment outcomes and occurrence of adverse drug events (negative association). Conclusion: Treatment success rate in the study cohort was sub-optimal (i.e., <75%). The poor success rate and high mortality are concerning, and requires immediate attention of the program managers and clinicians.

RESUMEN

Background: Ischemia reperfusion (I/R) play an imperative role in the expansion of cardiovascular disease. Sinomenine (SM) has been exhibited to possess antioxidant, anticancer, anti-inflammatory, antiviral and anticarcinogenic properties. The aim of the study was scrutinized the cardioprotective effect of SM against I/R injury in rat. Methods: Rat were randomly divided into normal control (NC), I/R control and I/R + SM (5, 10 and 20 mg/kg), respectively. Ventricular arrhythmias, body weight and heart weight were estimated. Antioxidant, inflammatory cytokines, inflammatory mediators and plasmin system indicator were accessed. Results: Pre-treated SM group rats exhibited the reduction in the duration and incidence of ventricular fibrillation, ventricular ectopic beat (VEB) and ventricular tachycardia along with suppression of arrhythmia score during the ischemia (30 and 120 min). SM treated rats significantly (P < 0.001) altered the level of antioxidant parameters. SM treatment significantly (P < 0.001) repressed the level of creatine kinase MB (CK-MB), creatine kinase (CK) and troponin I (Tnl). SM treated rats significantly (P < 0.001) repressed the tissue factor (TF), thromboxane B2 (TXB2), plasminogen activator inhibitor 1 (PAI-1) and plasma fibrinogen (Fbg) and inflammatory cytokines and inflammatory mediators. Conclusion: Our result clearly indicated that SM plays anti-arrhythmia effect in I/R injury in the rats via alteration of oxidative stress and inflammatory reaction.

RESUMEN

The rapid and sensitive diagnosis of the highly contagious severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is one of the crucial issues at the outbreak of the ongoing global pandemic that has no valid cure. Here, we propose a SARS-CoV-2 antibody conjugated magnetic graphene quantum dots (GQDs)-based magnetic relaxation switch (MRSw) that specifically recognizes the SARS-CoV-2. The probe of MRSw can be directly mixed with the test sample in a fully sealed vial without sample pretreatment, which largely reduces the testers' risk of infection during the operation. The closed-tube one-step strategy to detect SARS-CoV-2 is developed with home-made ultra-low field nuclear magnetic resonance (ULF NMR) relaxometry working at 118 µT. The magnetic GQDs-based probe shows ultra-high sensitivity in the detection of SARS-CoV-2 due to its high magnetic relaxivity, and the limit of detection is optimized to 248 Particles mL‒1. Meanwhile, the detection time in ULF NMR system is only 2 min, which can significantly improve the efficiency of detection. In short, the magnetic GQDs-based MRSw coupled with ULF NMR can realize a rapid, safe, and sensitive detection of SARS-CoV-2.

RESUMEN

INTRODUCTION: Viscosupplementation is widely practiced, to reduce pain in osteoarthritis (OA), using intra articular (IA) injections of hyaluronic acid (HA). In Europe, these products are class III medical devices, for which the Medical Device Regulation (MDR) requires clinical assessment, based on specific studies and/or a bibliographical review of equivalent devices. The purpose of this article is to present a comparative review between a family of devices (ARTHRUM, from LCA Pharmaceuticals, Chartres, France) and an extensive group of presumed equivalent IA HA devices or their controls, whose results have been published in Scientific journals. METHODS: To meet the criteria used in most ARTHRUM studies, the Western Ontario and McMaster Universities' index sub-scores were selected for pain (WOMAC A), stiffness (WOMAC B) and function (WOMAC C). The main criterion was the variation of the WOMAC A score from T0 (date of inclusion) to T6 (6 months). The other WOMAC criteria were assessed at T1, T3, T6 and complemented by OMERACT-OARSI rates of responders to the treatment. Fifty articles were selected, containing treatment details on more than 12,000 patients. These were divided into three groups: ARTHRUM, EQUIVALENTS and CONTROLS. To get quantitative comparisons, meta-analyses were performed for each criterion individually. The 95% confidence interval of each difference from baseline, was used to assess the clinical relevance, with reference to a minimum validated in OA literature. Comparisons between groups and tolerance assessment completed the investigation. RESULTS: For the WOMAC A, B and C scores, the full 95% CI was always above the minimal perceptible clinical improvement (MPCI), in the ARTHRUM and EQUIVALENTS groups, but not for all criteria in the CONTROLS group. In the comparisons, both ARTHRUM and EQUIVALENTS groups were significantly better than the CONTROLS group for each criterion. The effect size (ES) on pain, for the ARTHRUM and EQUIVALENTS groups, varied from 0.28 to 0.56 and from 0.23 to 0.27, respectively. Overall, ARTHRUM was estimated always non-inferior to EQUIVALENTS, and sometimes statistically and clinically superior. CONCLUSIONS: The comparison of ARTHRUM clinical studies, with studies selected through bibliographic research, leads to the conclusion that the clinical efficacy of the ARTHRUM medical devices, to reduce pain and improve the function in knee OA, during a six-month period, is at least as great as those of equivalent products. With good tolerance results (lowest rate of adverse events, and none of them serious), the risk benefit ratio favours using viscosupplementation with ARTHRUM.

RESUMEN

Full disintegration of Oral solid dosage forms is critically important to achieve reliable clinical performance of the drug. Tablets/capsules are supposed to be taken with a full glass of water; however, many patients do not follow this recommendation as they administer their medications with beverages other than water. This study aims to assess the impact of different commonly consumed beverages in Saudi Arabia on the disintegration times of common over-the-counter (OTC) medication tablets and capsules in the Kingdom of Saudi Arabia. Five immediate release OTC drugs were chosen: Fevadol®, Solpadeine®, Ralaxon®, Artiz ®, and Brufen®. The disintegration times of these medications were assessed using a disintegration test in five beverages: Coca-cola, arabic coffee, orange juice, buttermilk and an energy drink. Times were compared to the disintegration time in water under two temperature conditions (37 °C and 5 °C). All beverages significantly increased the disintegration times of fevadol, solpadeine, and relaxon in comparison with water. The same was found for burfen, except that arabic coffee did not significantly increase disintegration time (p > 0.05). The disintegration time of artiz tablets was also significantly influenced by all beverages, except for Coca-cola and the energy drink, which had no significant impact on the disintegration time. The tested beverages should not be used as substitutes for water when ingesting medications. Patients should be advised to avoid consuming beverages other than water with therapeutic products. Increasing public awareness of drug-beverage interactions is needed.

RESUMEN

This paper examines the impact on parent involvement in second grade in the Midwest Child-Parent Centers (MCPC), a high-quality preschool-to-third-grade school reform model. A new focus of research on early childhood programs is understanding how early childhood learning gains can be sustained. Two-generation programs that provide diverse family services may be one approach. The MCPC expansion was implemented for a cohort of over 2000 Chicago and Saint Paul students beginning in preschool. Based on a comparison of the program and usual-service comparison groups matched at the school level via propensity scores, ratings were obtained for a subset of the sample by teachers and parents on parent involvement in school in second grade. After accounting for potential attrition bias via multiple imputation and propensity score weighting, results indicated that MCPC participation was associated with significantly higher parent involvement in school at the end of second grade both in the aggregate sample (Effect Size = 0.19 SD) and in Chicago (ES = 0.24). Differences in Saint Paul, however, were small (ES = 0.15) and not statistically significant. Robustness testing using different model specifications revealed similar results. Implications for assessing and sustaining early childhood learning gains are discussed with a focus on recognizing that parental involvement is an integral component of high-quality programs.

RESUMEN

BACKGROUND: In the previous literature, patients' perceptions of medication consultation provided by pharmacists was found to poor, depending upon various factors, which may lead to poor compliance with medication instructions and, therefore, poor health outcomes. In the Kingdom of Saudi Arabia (KSA), this specific area has been overlooked to date, so this study aims to examine patients' perceptions of medication counselling and the factors that influence their likelihood of participating in medication counselling as well as determine the predictors of patients' likelihood to take part in medication counselling delivered by pharmacists in KSA. MATERIALS AND METHODS: A cross-sectional survey was conducted involving people over 18 years of age, who had purchased or collected medicine for their own use from community and/or hospital pharmacies within the past two years and who lived in Saudi Arabia. The data were analysed using IBM SPSS Statistics version 24. Descriptive statistics were applied to each item as well as linear regression and Pearson's correlation. RESULTS: Five hundred and eleven participants (male (n = 101), female (n = 410), the majority of whom were aged 18-24-years-old) were included. Almost an equal number of participants had accessed either community (CP) (n = 228: 45%) or hospital pharmacies (HP) (n = 283: 55%) within the past two years in regards to their condition and/or medication. The perceived susceptibility construct had weak positive correlations with all of the constructs being measured (r < 0.3). Perceived barriers had a weak negative relationship with likelihood (r < 0.3), which means that, as the perceived barriers increase, the perceived benefits and future likelihood to participate in medication counselling decrease. Linear regression analysis found that age (ß = -0.06; P =˃0.05), gender (ß = 0.14; P =˃0.05), education level (ß = -0.01; P =˃0.05) and type of pharmacies accessed (ß = -0.05; P =˃0.05) were non-significant predictors of the participants' likelihood of participating in medication counselling. CONCLUSION: In order to improve the medication consultation provided by pharmacists and, therefore, enhance the patients' experience and care, it is important to understand the public's views, concerns and demands regarding medication consultation, in order to provide the proper interventions and serve as a platform for developing a plan of action for good pharmacy practice.

RESUMEN

Risedronate is a nitrogen-containing bisphosphonate for the treatment and prevention of postmenopausal osteoporosis. The current work aims to develop a novel green HPLC-UV method for the rapid analysis of risedronate sodium in bulk and tablet formulation. The analyzed samples were separated on Waters Atlantis dC18 (150 mm × 3.9 mm; 5 µm) column using a green mobile phase consisting of potassium phosphate buffer pH 2.9 and potassium edetate buffer pH 9.5 in a ratio of 1:2, the final pH was adjusted to 6.8 with phosphoric acid, the mobile phase was pumped at a rate of 1.0 mL/min, with column temperature set at 30 °C, eluted samples were detected at 263 nm and the chromatographic run time was 3.0 min. The method was found to be linear over the concentration range of 14-140 µg/mL with a correlation coefficient (r2) of 0.9994. Accuracy and precision were evaluated from three QC samples (LQC, MQC and HQC) together with the five calibrators where the percentage accuracy was found to be 101.84%. Processed quality control samples of risedronate sodium were tested for stability at different conditions, short term, long term and freeze- thaw stability. The current method was further extended to study the content uniformity of Actonel® tablets following United States Pharmacopoeia (USP) guidelines. The proposed method was fully validated as per ICH guidelines.

RESUMEN

AIM: The aim of this study was to assess treatment modalities, treatment response, toxicity profile, disease progression and outcomes in 14 patients with a confirmed diagnosis of primary cutaneous T-cell lymphoma (PCTCL) treated with total skin electron beam therapy (TSEBT). BACKGROUND: Primary cutaneous lymphomas (PCLs) are extranodal non-Hodgkin lymphomas originating in the skin without evidence of extracutaneous disease at diagnosis. Despite advances in systemic and local therapy options, the management of advanced stages remains mostly palliative. MATERIALS AND METHODS: This is a retrospective study of patients with PCTCL, diagnosed and treated in a reference center in Mexico City, analyzing treatment modalities, response to treatment, long-term outcome, and mortality. RESULTS: Eight males (57%) and 6 (43%) females were identified. Most patients were stage IVA (n = 5, 36%) followed by stage IB and IIB (28.5% and 21.4%, respectively). Eleven patients received the low-dose RT scheme (12 Gy), 1 patient, the intermediate-dose RT scheme (24 Gy), and 2 patients, the conventional-dose RT scheme (36 Gy). Mean follow-up time was 4.6 years. At first follow-up examination, 6-8 weeks after radiotherapy, the overall response rate (ORR) for the cohort was 85%. The median PFS for the whole cohort was 6 months. CONCLUSION: This study reinforces the role of TSEBT when compared with other treatment modalities and novel agents. Low-dose TSEBT is now widely used because of the opportunity for retreatment.

RESUMEN

In order to compare the short-term efficacies of the live attenuated Mycoplasma gallisepticum (MG) vaccine strains ts-11 and 6/85, four groups of SPF chickens were vaccinated with each of the vaccines using eye drop and aerosol inoculations, and were subsequently challenged with a wild-type MG strain. When administered by the recommended routes (eye drop for ts-11 and fine aerosol for 6/85), both vaccines induced substantial and comparable levels of protection against airsacculitis and tracheitis caused by wild-type MG. The long-term efficacies of the two vaccines administered by the recommended route were also assessed. Serum antibody responses and colonization of the vaccines in the upper respiratory system were monitored at different time points after vaccination, and protective efficacies of the vaccines were evaluated at 36 weeks post vaccination as above. Systemic antibody response following ts-11 eye drop vaccination was initially strong but reduced gradually over time while, in contrast, that to 6/85 spray vaccination was initially weak but increased over time. Kinetics of the antibody response to the vaccines appeared to be correlated with the number of birds harbouring each vaccine in their upper respiratory system throughout the sampling timepoints. Regardless of the levels of serum antibodies or number of birds harbouring the vaccine, both vaccines induced substantial and comparable levels of protection against airsacculitis and tracheitis caused by wild-type MG. Therefore, kinetics of systemic antibody response and persistence in the upper respiratory system varies between vaccine strains; however, the levels of protection may not, at least up to 36 weeks post vaccination. RESEARCH HIGHLIGHTS The kinetics of systemic antibody response and persistence of the vaccine in the upper respiratory system varies between vaccine strains ts-11 and 6/85. The levels of protection induced by the two vaccines against virulent MG strain challenge are comparable when they are administered by the route recommended by their manufacturers.

RESUMEN

AIM: To investigate tumour motion tracking uncertainties in the CyberKnife Synchrony system with single fiducial marker in liver tumours. BACKGROUND: In the fiducial-based CyberKnife real-time tumour motion tracking system, multiple fiducial markers are generally used to enable translation and rotation corrections during tracking. However, sometimes a single fiducial marker is employed when rotation corrections are not estimated during treatment. MATERIALS AND METHODS: Data were analysed for 32 patients with liver tumours where one fiducial marker was implanted. Four-dimensional computed tomography (CT) scans were performed to determine the internal target volume (ITV). Before the first treatment fraction, the CT scans were repeated and the marker migration was determined. Log files generated by the Synchrony system were obtained after each treatment and the correlation model errors were calculated. Intra-fractional spine rotations were examined on the spine alignment images before and after each treatment. RESULTS: The mean (standard deviation) ITV margin was 4.1 (2.3) mm, which correlated weakly with the distance between the fiducial marker and the tumour. The mean migration distance of the marker was 1.5 (0.7) mm. The overall mean correlation model error was 1.03 (0.37) mm in the radial direction. The overall mean spine rotations were 0.27° (0.31), 0.25° (0.22), and 0.23° (0.26) for roll, pitch, and yaw, respectively. The treatment time was moderately associated with the correlation model errors and weakly related to spine rotation in the roll and yaw planes. CONCLUSIONS: More caution and an additional safety margins are required when tracking a single fiducial marker.

RESUMEN

Immunoglobulin E (IgE) is involved in the onset of allergic reaction, and the suppression of IgE production leads to alleviation of allergic symptoms. We found that mango peel ethanol extract (MPE) significantly suppresses IgE production by human myeloma cell line U266 cells, suggesting that MPE has an anti-allergic effect by inhibiting the production of IgE. Although mangiferin is contained in mango, which suppresses IgE production by U266 cells, it was not contained in MPE. We investigated the suppressive effect of MPE in 2,4-dinitrofluorobenzene (DNFB)-induced allergic contact dermatitis model mice. The elevation of serum IgE level was significantly suppressed by oral administration of MPE. Intake of MPE also suppressed the expression level of IL-4 in the DNFB-challenged ears, suggesting that MPE suppresses the IL-4-mediated maturation into IgE-producing cells. Our findings indicate that MPE has a potential to alleviate the increase in serum IgE level that is feature of type I allergy.

RESUMEN

Alcoholic beverages are enjoyed together with meals worldwide, but their excessive intake is associated with an increased risk of various diseases. We investigated whether S-allyl-L-cysteine sulfoxide (ACSO), a sulfuric odor precursor of garlic, suppresses elevation in plasma ethanol concentration by accelerating ethanol metabolism and preventing ethanol absorption from the gut in rats. ACSO and garlic extract with a high ACSO content (Garlic-H) suppressed elevation in concentrations of ethanol and acetaldehyde in plasma and promoted the activities of alcohol dehydrogenase and aldehyde dehydrogenase. However, ACSO and Garlic-H did not affect plasma acetate so much. Furthermore, we examined the change in plasma ethanol concentration by injecting ACSO or Garlic-H into the ligated stomach or jejunum together with ethanol solution. ACSO and Garlic-H suppressed the absorption of ethanol from the stomach and jejunum, but suppression in the jejunum was less than in the stomach. In conclusion, ACSO inhibits ethanol absorption and accelerates ethanol metabolism.

RESUMEN

Certain food components possess immunomodulatory effects. The aim of this study was to elucidate the mechanism of the immunostimulatory activity of Brassica rapa L. We demonstrated an enhancement of natural killer (NK) activity and interferon (IFN)-γ production in mice that were orally administered an insoluble fraction of B. rapa L. The insoluble fraction of B. rapa L. significantly induced IFN-γ production in mouse spleen cells in an interleukin (IL)-12-dependent manner, and NK1.1+ cells were the main cells responsible for producing IFN-γ. Additionally, the results suggested that the active compounds in the insoluble fraction were recognized by Toll-like receptor (TLR) 2, TLR4, and C-type lectin receptors on dendritic cells, and they activated signaling cascades such as MAPK, NF-κB, and Syk. These findings suggest that B. rapa L. is a potentially promising immuno-improving material, and it might be useful for preventing immunological disorders such as infections and cancers by activating innate immunity.

RESUMEN

This study aimed to compare the activity of four shoulder muscles in individuals with low back pain (LBP), spinal cord injuries (SCI) and a control group, during one-handed load transfer trials. Nine individuals with minimum one-year of LBP, eleven with thoracic/lumbar SCI and nine healthy controls participated in this study. The activations of anterior deltoid, upper trapezius, infraspinatus and pectoralis major were recorded by surface EMG during one-handed transferring of a cylinder from a home shelve to six spatially distributed target shelves. The integrated EMG values were compared using repeated measure ANOVA. Both LBPs and SCIs had higher anterior deltoid activation and LBPs required more upper trapezius activation than controls (p < 0.05). The spatial position of the targets also significantly influenced demands for these two muscles. The anterior deltoid and upper trapezius in LBP and SCI individuals are under higher demand during occupational load transfer tasks. Practitioner Summary: This study aimed to compare the activation of four shoulder muscles in individuals with low back pain, spinal cord injuries and healthy condition. EMG analysis showed that the injured groups required more upper trapezius and anterior deltoid activation during load transfer tasks, which may predispose them to muscle overexertion.

RESUMEN

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.

RESUMEN

Background The Approaches and Study Skills Inventory for Students (ASSIST) questionnaire assesses whether learners prefer a deep, strategic or surface approach to learning. This study aimed to establish the effect of time since qualification, gender and work role on ASSIST scores of General Practitioners (GPs) and GP Specialist Trainees (GPSTs). Methods An anonymous online questionnaire with demographic questions and the ASSIST survey was completed by 1005 GPs and GPSTs from across the United Kingdom. Results Of the 544 GPs and 461 GPSTs completing the survey, 96.5% preferred a deep and/or strategic approach to learning. There was a significant increase in the preference for a deep approach with time from graduation and significantly less preference for a surface approach. There was no significant change in any of the scores over the GPST years. Men had significantly higher scores for a deep approach than women. Conclusions GPs and GPSTs prefer deep and strategic approaches to a surface approach. While higher levels of GP experience are associated with a higher deep approach score and a lower surface approach score, this change is not seen during progression through GP training. Men have higher scores for a deep approach than women.

RESUMEN

AIM: To identify the most reproducible technique of patient positioning and immobilization during pelvic radiotherapy. BACKGROUND: Radiotherapy plays an important role in the treatment of pelvic malignancies. Errors in positioning of patient are an integral component of treatment. The present study compares two methods of immobilization with no immobilization with an aim of identifying the most reproducible method. MATERIALS AND METHODS: 65 consecutive patients receiving pelvic external beam radiotherapy were retrospectively analyzed. 30, 21 and 14 patients were treated with no-immobilization with a leg separator, whole body vacuum bag cushion (VBC) and six point aquaplast immobilization system, respectively. The systematic error, random error and the planning target volume (PTV) margins were calculated for all the three techniques and statistically analyzed. RESULTS: The systematic errors were the highest in the VBC and random errors were the highest in the aquaplast group. Both systematic and random errors were the lowest in patients treated with no-immobilization. 3D Systematic error (mm, mean ± 1SD) was 4.31 ± 3.84, 3.39 ± 1.71 and 2.42 ± 0.97 for VBC, aquaplast and no-immobilization, respectively. 3D random error (mm, 1SD) was 2.96, 3.59 and 1.39 for VBC, aquaplast and no-immobilization, respectively. The differences were statistically significant between all the three groups. The calculated PTV margins were the smallest for the no-immobilization technique with 4.56, 4.69 and 4.59 mm, respectively, in x, y and z axes, respectively. CONCLUSIONS: Among the three techniques, no-immobilization technique with leg separator was the most reproducible technique with the smallest PTV margins. For obvious reasons, this technique is the least time consuming and most economically viable in developing countries.
