Detection and evaluation of haemophilic arthropathy: Which tools may be considered more reliable.

INTRODUCTION: Progressive arthropathy is the main cause of morbidity in patients with severe haemophilia. Diagnostic imaging can detect even subclinical arthropathy and impact prophylactic treatment. However, in most clinical settings the regular joint evaluation and follow-up are based on clinical evaluation and patient's personal reporting of problems, while diagnostic imaging is not regularly employed. AIM: The aim of our prospective study was to assess how ultrasound (US), clinical examination, patient's subjective assessment and certain laboratory biomarkers correlate with magnetic resonance imaging (MRI) for detection and evaluation of haemophilic arthropathy in order to determine which tool is the most reliable. METHODS: The study included 30 patients with severe haemophilia (age range 16-49 years). MRI (IPSG), US (HEAD-US), clinical examination (HJHS 2.1) and patient's subjective assessment of elbows, knees and ankles were performed; additionally, blood samples for laboratory analysis were taken (s-25-OH vitamin D, s-ferritin, s-C-terminal telopeptide of type I collagen, s-N-terminal propeptide of type I procollagen and s-cartilage oligomeric matrix protein). MRI results were used as a reference standard for joint status. Pearson's r was used to assess correlation of other methods with MRI. RESULTS: The correlation with MRI was the highest for US (r = .92), considerably higher than for clinical evaluation (r = .62) and patient's subjective assessment (r = .66). There was no correlation between the presence or degree of haemophilic arthropathy and any of the laboratory biomarkers. CONCLUSION: The results of our study warrant the inclusion of US into the regular follow-up of patients with severe haemophilia, where the equipment and staffing permit.

Switching to Denosumab or Bisphosphonates After Completion of Teriparatide Treatment in Women With Severe Postmenopausal Osteoporosis.

OBJECTIVE: To compare bone mineral density (BMD) changes after 12 months of treatment with denosumab or bisphosphonates in postmenopausal women with severe osteoporosis after stopping teriparatide therapy. METHODS: We retrospectively analyzed 140 postmenopausal women (mean age, 74.2 years) with severe osteoporosis who had been treated with teriparatide for 18 to 24 months at our outpatient clinic in a tertiary endocrine center between 2006 and 2015. After stopping teriparatide therapy, they continued treatment with a bisphosphonate (alendronate, risedronate, ibandronate, or zoledronic acid) or denosumab while receiving daily vitamin D and calcium. BMD at the lumbar spine (LS), total hip (TH), and femoral neck (FN) was measured by dual energy x-ray absorptiometry when teriparatide therapy was discontinued (baseline) and after 12 months of further treatment. Multivariate linear regression models were used to identify the predictors of BMD gain. RESULTS: After stopping teriparatide therapy, 70 women continued treatment with bisphosphonates and 70 received denosumab. LS, but not TH or FN, BMD gain was significantly greater in the denosumab group than in the bisphosphonates group at 12 months. Multivariate analysis showed that BMD gain at the LS was negatively associated with bisphosphonate versus denosumab treatment and positively associated with baseline serum total procollagen type I N-terminal propeptide. BMD gains at the FN were predicted by higher baseline serum urate levels. BMD gains at the TH and FN were negatively associated with pretreatment BMD gains at the same site. CONCLUSION: Twelve months after stopping teriparatide therapy, sequential denosumab treatment appeared to yield higher additional LS BMD gain on average compared with bisphosphonates treatment.

Long-term recovery of muscle strength after denervation in the fibular division of the sciatic nerve.

INTRODUCTION: The probability and degree of muscle recovery after lesions of long peripheral nerves have not been assessed quantitatively. METHODS: Twelve adults with closed injuries of the fibular division of the sciatic nerve with complete denervation of associated muscles were followed-up for 2-10 years. The onset of reinnervation was detected electromyographically. Calf circumference and maximum voluntary isometric contraction (MVIC) of foot dorsiflexion were measured on both sides during 2-4 visits. RESULTS: Reinnervation occurred in 11 patients after an average of 13 months. MVIC on the affected side was 2%-27% of that on the unaffected side (average 11%) and remained stable for the following 2-3 years. Correlations and mixed-model regressions confirmed that the degree of recovery was negatively associated with duration of denervation. CONCLUSIONS: Reinnervation occurs in about 90% of patients within about 1 year. About 10% of baseline dorsiflexion strength is permanently recovered, which is functionally relevant.

A NEW CLINICAL PREDICTION CRITERION ACCURATELY DETERMINES A SUBSET OF PATIENTS WITH BILATERAL PRIMARY ALDOSTERONISM BEFORE ADRENAL VENOUS SAMPLING.

OBJECTIVE: Adrenal venous sampling (AVS) is the only available method to distinguish bilateral from unilateral primary aldosteronism (PA). AVS has several drawbacks, so it is reasonable to avoid this procedure when the results would not affect clinical management. Our objective was to identify a clinical criterion that can reliably predict nonlateralized AVS as a surrogate for bilateral PA that is not treated surgically. METHODS: A retrospective diagnostic cross-sectional study conducted at Slovenian national endocrine referral center included 69 consecutive patients (mean age 56 ± 8 years, 21 females) with PA who underwent AVS. PA was confirmed with the saline infusion test (SIT). AVS was performed sequentially during continuous adrenocorticotrophic hormone (ACTH) infusion. The main outcome measures were variables associated with nonlateralized AVS to derive a clinical prediction rule. RESULTS: Sixty-seven (97%) patients had a successful AVS and were included in the statistical analysis. A total of 39 (58%) patients had nonlateralized AVS. The combined criterion of serum potassium ≥3.5 mmol/L, post-SIT aldosterone <18 ng/dL, and either no or bilateral tumor found on computed tomography (CT) imaging had perfect estimated specificity (and thus 100% positive predictive value) for bilateral PA, saving an estimated 16% of the patients (11/67) from unnecessary AVS. The best overall classification accuracy (50/67 = 75%) was achieved using the post-SIT aldosterone level <18 ng/dL alone, which yielded 74% sensitivity and 75% specificity for predicting nonlateralized AVS. CONCLUSIONS: Our clinical prediction criterion appears to accurately determine a subset of patients with bilateral PA who could avoid unnecessary AVS and immediately commence with medical treatment.

Attitudes of Slovene paediatricians to end-of-life care.

AIMS: The aims of this study were to assess the attitudes of Slovene paediatricians to aspects of end-of-life (EOL) care and compare these attitudes between paediatric intensivists, paediatric specialists and paediatric residents. METHODS: We performed a cross-sectional survey, using a specifically designed 43-item anonymous questionnaire. RESULTS: We included 323 out of 586 Slovene paediatricians and residents, while 46.7% (151 of 323) of them responded to our questionnaire. More than half of intensivists (54.2%) had sought counsel from the Committee for Medical Ethics in the past as compared with 12.0% and 12.1% of specialists and residents, respectively (P < 0.001). The decision to limit life-sustaining treatment (LST) was found to be ethically acceptable in all groups of respondents. The highest level of agreement was found in residents (90.2%), followed by 83.3% among intensivists and 73.8% among specialists (P = not statistically significant (NS)). Disagreement with termination of hydration was highest among residents (85%) and intensivists (79.2%) while it was lower among specialists (66.7%) (P = NS). Patient's best interest, good clinical practice and patient's autonomous decision were graded as the top three aspects of the EOL care, while cost effectiveness and availability of patient's bed in intensive care were the least important. CONCLUSIONS: The decision to limit LST measures was found to be ethically acceptable for Slovene paediatricians. No major differences were found among paediatric intensivists, specialist paediatricians and paediatric residents in the attitudes towards the EOL care.

Immunological status in patients with lower limb amputation due to peripheral arterial disease before and after comprehensive rehabilitation.

The immunological status before and after a comprehensive rehabilitation program was studied. Seven persons (4 males, 3 females, mean age 71.4 years) after lower limb amputation due to peripheral arterial disease (PAD) were subject to standard comprehensive rehabilitation program for amputees of four-week duration, which included training in activities of daily living, daily exercise of various types, training of crutch-assisted gait and use of leg prosthesis, and mild transcutaneous electrical stimulation. Before and after rehabilitation, peripherial blood was collected and the number and ratio of white blood cells were determined and analysed for the expression of cell surface antigens (CD3, CD4, CD8, CD19, CD25, CD69), cytokines (IFN-gamma, IL-4) and phagocytosis/oxidative killing functional tests. Due to strict patient selection criteria excluding serious accompanying disease, immunological parameters were within normal limits already before rehabilitation. After rehabilitation, an increase in oxidative burst was observed in monocytes and neutrophil granulocytes, but statistically significant only in monocytes. The expression of CD69 molecules by T cells and monocytes was significantly increased, as well as the expression of IL-4 by T cells. A significant decrease in the ratio of CD4 to CD8 cells was also found, but not a clinically critical one. It can therefore be concluded that the comprehensive rehabilitation treatment in patients with lower limb amputation due to PAD led to some--prevailingly positive--immunological changes, which were consistent with the patients' improved physical condition and clinical status.

Dexamethasone produces dose-dependent inhibition of sugammadex reversal in in vitro innervated primary human muscle cells.

BACKGROUND: Corticosteroids are frequently used during anesthesia to provide substitution therapy in patients with adrenal insufficiency, as a first-line treatment of several life-threatening conditions, to prevent postoperative nausea and vomiting, and as a component of multimodal analgesia. For these last 2 indications, dexamethasone is most frequently used. Due to the structural resemblance between aminosteroid muscle relaxants and dexamethasone, concerns have been raised about possible corticosteroid inhibition in the reversal of neuromuscular block by sugammadex. We thus investigated the influence of dexamethasone on sugammadex reversal of rocuronium-induced neuromuscular block, which could be relevant in certain clinical situations. METHODS: The unique co-culture model of human muscle cells innervated in vitro with rat embryonic spinal cord explants to form functional neuromuscular junctions was first used to explore the effects of 4 and 10 µM rocuronium on muscle contractions, as quantitatively evaluated by counting contraction units in contraction-positive explant co-cultures. Next, equimolar and 3-fold equimolar sugammadex was used to investigate the recovery of contractions from 4 and 10 µM rocuronium block. Finally, 1, 100, and 10 µM dexamethasone (normal, elevated, and high clinical levels) were used to evaluate any effects on the reversal of rocuronium-induced neuromuscular block by sugammadex. RESULTS: Seventy-eight explant co-cultures from 3 time-independent experiments were included, where the number of contractions increased to 10 days of co-culturing. Rocuronium showed a time-dependent effect on depth of neuromuscular block (4 µM rocuronium: baseline, 10, 20 minutes administration; P < 0.0001), while the dose-dependent effect was close to nominal statistical significance (4, 10 µM; P = 0.080). This was reversed by equimolar concentrations of sugammadex, with further and virtually complete recovery of contractions with 3-fold equimolar sugammadex (P < 0.0001). Dexamethasone diminished 10 µM sugammadex-induced recovery of contractions from rocuronium-induced neuromuscular block in a dose-dependent manner (P = 0.026) with a higher sugammadex concentration (30 µM) being close to statistically significantly improving recovery (P = 0.065). The highest concentration of dexamethasone decreased the recovery of contractions by equimolar sugammadex by 26%; this effect was more pronounced when 3-fold equimolar (30 µM) sugammadex was used for reversal (48%). CONCLUSIONS: This is the first report in which the effects of rocuronium and sugammadex interactions with dexamethasone have been studied in a highly accessible in vitro experimental model of functionally innervated human muscle cells. Sugammadex reverses rocuronium-induced neuromuscular block; however, concomitant addition of high dexamethasone concentrations diminishes the efficiency of sugammadex. Further studies are required to determine the clinical relevance of these interactions.

Experiences of Slovene ICU physicians with end-of-life decision making: a nation-wide survey.

BACKGROUND: Advances in intensive care medicine have enormously improved ability to successfully treat seriously ill patients. However, intensive treatment and prolongation of life is not always in the patient's best interest, and many ethical dilemmas arise in end-of-life (EOL) situations. We aimed to assess intensive care unit (ICU) physicians' experiences with EOL decision making and to compare the responses according to ICU type. MATERIAL AND METHODS: A cross-sectional survey was performed in all 35 Slovene ICUs, using a questionnaire designed to assess ICU physician experiences with EOL decision making, focusing on limitations of life-sustaining treatments (LST). RESULTS: We distributed 370 questionnaires (approximating the number of Slovene ICU physicians) and 267 were returned (72% response rate). The great majority of ICU physicians reported using do-not-resuscitate (DNR) orders (97%), withholding LST (94%), and withdrawing antibiotics (86%) or inotropes (95%). Fewer ICU physicians reported withdrawing mechanical ventilation (52%) or extubating patients (27%). Hydration was reported to be only rarely terminated (76% of participants reported never terminating it). In addition, 63% of participants had never encountered advance directives, and 39% reported to "never" or "rarely" participating in decision making with relatives of patients. Nurses were reported to be "never" or "rarely" involved in the EOL decision making process by 84% of participants. CONCLUSIONS: Limitation of LST was regularly used by Slovene ICU physicians. DNR orders and withholding of LST were the most commonly used measures. Hydration was only rarely terminated. In addition, use of advance directives was almost non-existent in practice, and the patients' relatives and nurses only infrequently participated in the decision making.

Body mass index and anthropometric characteristics of the hand as risk factors for carpal tunnel syndrome.

Carpal tunnel syndrome (CTS) is the most common peripheral entrapment compressive neuropathy in the upper limbs. It is often correlated with personal factors of individuals, not only with certain medical conditions and jobs. The study aimed at clarifying the association of carpal tunnel syndrome with anthropometric characteristics of the hand and body mass index (BMI) as independent risk factors. A total of 100 subjects participated: 50 patients with electro-diagnostically confirmed CTS and 50 healthy volunteers without CTS symptoms as control group, each group including 37 women and 13 men. Height, weight, BMI, wrist depth and width, wrist index, hand shape index, digit index, palm length, palm width, third finger length and ratio of hand length to body height were assessed in all participants. To determine independent risk factors for CTS, multiple logistic regression was used. Wrist index and wrist width were significantly higher in CTS patients than in the control group. The estimated optimal threshold of wrist index for prediction of CTS was 0.69, above which the odds for CTS were estimated to increase 42-fold. Elevated BMI correlated with bilateral CTS in both genders. The study identified wrist index, BMI and ratio of hand length to body height ratio as independent risk factors for CTS.

Differences in respiratory function, depressive symptoms and quality of life between patients with hereditary motor and sensory neuropathy and myotonic dystrophy undergoing maintenance rehabilitation.

Hereditary motor and sensory neuropathy (HMSN) and myotonic dystrophy (MD) are chronic neuromuscular diseases that cause progressive muscular impairment and impact patient's quality of life. Conflicting findings in existing literature underscore the need for focussed research on specific health aspects in these patients. The aim of the study was to explore the differences in respiratory function, depressive symptoms and quality of life between patients with HMSN and MD undergoing maintenance rehabilitation. Our prospective observational study included 62 HMSN patients (median age 53.5, range 19-79 years; 38 women) and 50 MD patients (median age 54.0, range 18-77 years; 34 women) undergoing maintenance rehabilitation. They performed respiratory function tests (vital capacity, forced vital capacity, forced expiratory volume and peak expiratory flow) and respiratory muscle strength tests (maximum inspiratory pressure, maximum expiratory pressure and sniff nasal inspiratory force). The Center for Epidemiological Studies-Depression Scale was used to evaluate depression, and their health-related quality of life was assessed using the Quality of Life in Genetic Neuromuscular Disease Questionnaire. Using logistic regression, we examined group-difference in presence of depressive symptoms while accounting for age, symptoms duration, and marital status. Multiple linear regression was used to assess the difference in quality-of-life scores, adjusting for age, gender, and symptoms' duration. The HMSN group achieved statistically significantly better results than the MD group on all respiratory measures (about 17% absolute difference in the respiratory function measures and 30% relative difference in the respiratory muscle strength measures on average). Both groups exhibited a high level of depression symptoms (HMSN 24%, MD 44%; estimated adjusted odds-ratio MD vs. HMSN 1.9, 95% CI 0.8-4.5, P  = 0.127). We did not find a statistically significant difference between the groups regarding quality-of-life domains, though a trend towards better quality-of-life among the HMSN patients could be observed. The implication for future practice is that the MD patients would potentially benefit the most from targeted respiratory-rehabilitation interventions, and both groups could benefit from focussed mental-health interventions.

Effects of device-performed and manual hip traction and vibration therapy in older adults with symptomatic hip osteoarthritis: A randomized single-blind controlled trial.

BACKGROUND: Traction-and-vibration-therapy (TVT) relieves pain in participants with hip osteoarthritis. Hip TVT is usually performed manually by the physiotherapist. OBJECTIVE: A medical device was developed to perform hip-TVT in order to investigate effects on hip disability, pain intensity, recovery of balance and functional mobility in older adults with hip osteoarthritis and also to reduce physiotherapists' workload and help standardize treatment of hip TVT. METHODS: In a block-randomized 3-month controlled trial involving 28 older adult participants with symptomatic primary hip osteoarthritis (SPHOA), one group (n= 10) received device-performed TVT, one (n= 10) manual TVT, and one (n= 8) sham/placebo therapy. Hip disability (Harris Hip Score), pain intensity (visual-analog-scale), recovery of balance and gait (Functional Gait Assessment) and functional mobility (Timed-Up-and-Go-test) were assessed at baseline, after 3 weeks without intervention, and after 3-month intervention. RESULTS: The Device TVT and Manual TVT groups exhibited superior outcomes compared to the Placebo group in terms of hip disability (p= 0.005 and p< 0.001, respectively), pain intensity (p= 0.002 and p< 0.001, respectively), and functional mobility (TUG) (p= 0.012 and p= 0.011, respectively). Furthermore, the recovery of balance and gait (FGA) showed a significant improvement in the Device TVT group when compared to the Placebo group (p= 0.043). The effect sizes ranged from 0.17 to 0.51, indicating moderate to large effects. CONCLUSION: Device-performed-TVT is comparable to manual hip-TVT for reducing pain and improving mobility in older adults with SPHOA, and may be beneficial in terms of reducing physiotherapists' workload and better therapy standardization.

Health-related quality-of-life during rehabilitation in patients with critical illness neuropathy/myopathy after severe coronavirus disease 2019.

Our aim was to evaluate health-related quality-of-life (HRQoL) of the patients with critical illness neuropathy and/or myopathy after severe COVID-19 during their rehabilitation. The prospective cohort study included 157 patients (median age 64 years) admitted to rehabilitation. HRQoL was assessed the using European Quality 5-Dimensions questionnaire [EQ-5D index , range 0(or exceptionally less) to 1, and Visual Analogue Scale (VAS), range 0-100], which was completed by the patients at admission and discharge. Additionally, they were assessed with the de Morton Mobility Index (DEMMI), the 6-Minute Walk Test (6MWT), and the Functional Independence Measure (FIM). Median EQ-5D index was 0.32 and median EQ VAS was 48 at admission, and median EQ-5D index was 0.61 and median EQ VAS 80 at discharge. Some or extreme problems were reported by 154 (98%) patients regarding the mobility dimension, 151 (96%) regarding usual activities, 136 (87%) regarding self-care, 84 (54%) regarding pain or discomfort dimension, and 52 patients (34%) regarding anxiety or depression at admission. At discharge, some or extreme problems were still reported by 96 patients (61%) regarding mobility, 95 (61%) regarding usual activities, 70 patients (45%) regarding pain or discomfort, 46 (29%) regarding self-care, and 19 patients (12%) regarding anxiety or depression. At the same time, the patients exhibited significant improvements in the DEMMI (median increased from 41 to 67 points), 6MWT (from 60 to 293 m) and motor FIM (from 56 to 84 points). The improvement of the self-reported HRQoL was, thus, paralleled by the improvements in clinician-assessed mobility, walking endurance and functional independence.

Slovenian version of the scoliosis research society instrument-22 revised (SRS-22r) in adolescents and adults: Psychometric properties and some implications.

PURPOSE: This study aimed to provide a reliable and valid translation of the Scoliosis Research Society-22 (SRS-22r) questionnaire, compare it with the EQ-5D-5 L questionnaire, and analyse health-related quality of life (HRQoL) of patients with idiopathic scoliosis (IS) in Slovenia in order to potentially improve their rehabilitation processes. METHODS: A matched-case-control study was performed to assess internal consistency reliability, test-retest reliability, concurrent validity, and discriminative validity. The questionnaire was returned by 25 adolescent IS patients, 25 adult IS patients, and 25 healthy controls (87%, 71%, and 100% response rate, respectively). RESULTS: Internal consistency was high for all four scales in the adult IS group, but lower among the adolescent patients. Test-retest reliability of the SRS-22r was high to very high in both patient groups. Correlations between SRS-22r and EQ-5D-5 L were low or close to zero among adolescent patients and moderate or high among adult IS patients. SRS-22r domain scores were statistically significantly different between adult patients and healthy controls. CONCLUSION: The study proved that the Slovenian version of SRS-22r has the psychometric properties needed to measure HRQoL, whereby it appears to be more reliable for adults than adolescents. When used with IS adolescents, SRS-22r is affected by a severe ceiling effect. It could be used for longitudinal follow-up of adult patients after rehabilitation treatment. Additionally, some important issues that adolescents and adults with IS are faced with were identified.

Therapeutic electric stimulation does not affect immune status in healthy individuals - a preliminary report.

BACKGROUND: Neuromuscular electric stimulation is widely used for muscle strengthening in clinical practice and for preventative purposes. However, there are few reports on the effects of electric stimulation on the immune response of the organism, and even those mainly describe the changes observed immediately after the electrotherapeutic procedures. The objective of our study was to examine the possible immunological consequences of moderate low-frequency transcutaneous neuromuscular electric stimulation for quadriceps muscle strengthening in healthy individuals. METHODS: The study included 10 healthy volunteers (5 males, 5 females, mean age 37.5 years). At the beginning and after a two-week electric stimulation program, muscle strength was measured and peripheral blood was collected to analyse white blood cells by flow cytometry for the expression of cell surface antigens (CD3, CD19, CD4, CD8, CD4/8, DR/3, NK, Th reg, CD25 + CD3+, CD25 + CD4+, CD25 + CD8+, CD69 + CD3+, CD69 + CD4+, CD69 + CD8+) and phagocytosis/oxidative killing function. RESULTS: Muscle strength slightly increased after the program on the dominant and the nondominant side. No statistically or clinically significant difference was found in any of the measured blood and immune cells parameters as well as phagocytosis and oxidative burst function of neutrophil granulocytes and monocytes one day after the program. CONCLUSIONS: The program of transcutaneous low-frequency electric stimulation slightly strengthened the quadriceps femoris muscle while producing no changes in measured immunological parameters. Hence, therapeutic low-frequency electric stimulation appears not to be affecting the immune response of healthy persons.

Inert gas narcosis has no influence on thermo-tactile sensation.

Contribution of skin thermal sensors under inert gas narcosis to the raising hypothermia is not known. Such information is vital for understanding the impact of narcosis on behavioural thermoregulation, diver safety and judgment of thermal (dis)comfort in the hyperbaric environment. So this study aimed at establishing the effects of normoxic concentration of 30% nitrous oxide (N(2)O) on thermo-tactile threshold sensation by studying 16 subjects [eight females and eight males; eight sensitive (S) and eight non-sensitive (NS) to N(2)O]. Their mean (SD) age was 22.1 (1.8) years, weight 72.8 (15.3) kg, height 1.75 (0.10) m and body mass index 23.8 (3.8) kg m(-2). Quantitative thermo-tactile sensory testing was performed on forearm, upper arm and thigh under two experimental conditions: breathing air (air trial) and breathing normoxic mixture of 30% N(2)O (N(2)O trial) in the mixed sequence. Difference in thermo-tactile sensitivity thresholds between two groups of subjects in two experimental conditions was analysed by 3-way mixed-model analysis of covariance. There were no statistically significant differences in thermo-tactile thresholds either between the Air and N(2)O trials, or between S and NS groups, or between females and males, or with respect to body mass index. Some clinically insignificant lowering of thermo-tactile thresholds occurred only for warm thermo-tactile thresholds on upper arm and thigh. The results indicated that normoxic mixture of 30% N(2)O had no influence on thermo-tactile sensation in normothermia.

Psychomotor function during mild narcosis induced by subanesthetic level of nitrous oxide: individual susceptibility beyond gender effect.

OBJECTIVE: We investigated the effect of narcosis induced by subanesthetic concentrations of nitrous oxide (N2O), a behavioral analogue for hyperbaric nitrogen, on psychomotor performance. In particular, we assessed individual susceptibility to narcosis. METHODS: The participants were 12 female and 12 male undergraduate students. Psychomotor assessment was conducted with a computerized Visual Simple Reaction Time (VSRT) test, and Trail Making Tests Part A (TMTA) and Part B (TMT-B). The tests were conducted on two separate occasions in the following order: VSRT, TMT-A, TMT-B. On the first occasion participants conducted the tests breathing room air (air trial), and during the second test they conducted the tests while breathing a normoxic mixture containing 30% N2O (N2O trial). RESULTS: Males had significantly (p = 0.036) shorter VSRT in the air trials. There was no effect of gender on psychomotor performance in the N2O trials. Overall, mean performance in the N2O trials degraded significantly (p = 0.004) only in VSRT. Performance of individual participants exhibited different and inconsistent direction of change in the N2O trials. CONCLUSION: N2O-induced alterations in psychomotor function are primarily dependent on individual susceptibility to narcosis (i.e., concentration threshold).

Time trends in prescribing habits of anxiolytics and antidepressants in Slovenian family practices (with emphasis on elderly patients).

The aim of the study was to investigate prescription of anxiolytics and antidepressants among Slovenian family physicians regarding drug class with an emphasis on the elderly population and possible time-trends. Exploratory survey and register-based analysis of anxiolytic and antidepressant prescriptions of one hundred family physicians in Slovenia was performed in 2005 and 2008. Drugs included in the study were classified according to the Anatomical-Therapeutic-Chemical (ATC) drug classification system, and ATC data were used to calculate defined daily doses (DDD) per 1,000 practice population per day. The most often prescribed anxiolytics and antidepressants were identified and anxiolytic/antidepressant ratio was estimation by patient age-group for the two studied years. Benzodiazepines showed highest share in the overall utilization of psychotropic drugs. The ratio between short- and long-acting benzodiazepines decreased by about one tenth during the observed period. Long-acting benzodiazepines were prescribed more often to the older patients. The decrease in anxiolytic/antidepressant ratio from 2005 to 2008 was the smallest in the elderly population. Further research is needed to ascertain the prescribers' attitudes in order to devise strategies to further improve prescribing performance in elderly patients.

Occupational priorities and needs of blind and partially sighted people entering the labor market in Slovenia.

BACKGROUND: People with vision impairment are a growing group of clients for occupational therapists, particularly those working in vocational rehabilitation. OBJECTIVE: To examine the occupational priorities and performance issues of blind and partially sighted people entering vocational rehabilitation in Slovenia. Possible differences between priorities and issues among diagnostic groups and in relation to the rehabilitation outcome were explored. METHODS: Records of 42 clients referred to vocational rehabilitation at the University Rehabilitation Institute in Ljubljana between 2007 and 2019 were reviewed. Information on self-perceived occupational priorities and issues was obtained from the Canadian Occupational Performance Measure (COPM). RESULTS: Household and other unpaid work was identified the most frequently (20%) as a priority, followed by job-seeking (19%) and community mobility (15%). Job-seeking was the top performance issue (43%), followed by community mobility (21%) and household management (19%). On the 1-10 scale, the average occupational performance and satisfaction scores were 6.7 and 6.5, respectively; no statistically significant differences in relation to the diagnosis or the rehabilitation outcome were observed. CONCLUSION: The results highlight the client-identified occupational priorities and issues beside job-seeking that need to be considered in planning occupational therapy and supporting the persons with visual impairments entering the labor market.

Validation of three novel clinical prediction tools for primary aldosteronism subtyping.

The 20-point clinical prediction SPACE score, the aldosterone-to-lowest potassium ratio (APR), aldosterone concentration (AC) and the AC relative reduction rate after saline infusion test (SIT) have recently been proposed for primary aldosteronism (PA) subtyping prior to adrenal vein sampling (AVS). To validate those claims, we performed a retrospective cross-sectional study that included all patients at our center who had positive SIT to confirm PA and were diagnosed with either bilateral disease (BPA) according to AVS or with lateralized disease (LPA) if biochemically cured after adrenalectomy from November 2004 to the end of 2019. Final diagnoses were used to evaluate the diagnostic performance of proposed clinical prediction tools. Our cohort included 144 patients (40 females), aged 32-72 years (mean 54 years); 59 with LPA and 85 with BPA. The originally suggested SPACE score ≤8 and SPACE score >16 rules yielded about 80% positive predictive value (PPV) for BPA and LPA, respectively. Multivariate analyses with the predictors constituting the SPACE score highlighted post-SIT AC as the most important predictor of PA subtype for our cohort. APR-based tool of <5 for BPA and >15 for LPA yielded about 75% PPV for LPA and BPA. The proposed post-SIT AC <8.79 ng/dL criterion yielded 41% sensitivity and 90% specificity, while the relative post-SIT AC reduction rate of >33.8% criterion yielded 80% sensitivity and 51% specificity for BPA prediction. The application of any of the validated clinical prediction tools to our cohort did not predict the PA subtype with the high diagnostic performance originally reported.

Life satisfaction and athletic identity among Olympic para-alpine skiers: a survey.

The objective of this study was to examine life satisfaction and athletic identity among para-alpine skiers and explore their associations with sociodemographic, sports practice, and disability-related characteristics of the participants. The respondents to the on-site survey were 129 para-alpine ski racers with acquired disability from 33 countries on all five continents who competed in the Paralympic games in Sochi (aged 16-53 years, mean and median 30 years, 100 men). Two self-developed assessment instruments were used - a 7-point Likert-type life-satisfaction questionnaire probing seven domains (health, family, education, freedom, friends, travelling, and self) and the Athletic Identity Scale (AIS; possible score range 17-85). The independence between life-satisfaction items was confirmed by low interitem correlations (largest absolute value <0.25, 15 of 21, and <0.15). The estimated internal-consistency reliability (Guttman lambda-2) of AIS was 0.65. The reported life satisfaction was very high (median of 6 for all domains except education, where it was 5). Like life-satisfaction ratings, the AIS scores were also very high on average (mean and median score 81). In general, the level of life satisfaction and athletic identity were not notably associated with sociodemographic, sports practice, and disability characteristics of the participants. The likely reason is high average and, hence, low variability of life-satisfaction ratings, as well as imperfect metric characteristics of the AIS. Nonetheless, the overall findings encourage further research into factors that drive the participation of disabled athletes in (winter) Paralympic games and the possible role of the rehabilitation process in this regard.
