Social inequality in obesity in an Eastern Mediterranean population: evidence from a national health survey in Cyprus.

Background: We aimed to explore socioeconomic factors associated with obesity among adults and to investigate social inequality in obesity prevalence in Cyprus. Study design: Cross-sectional study. Methods: We conducted a survey among 3,021 Greek-Cypriots aged 25-64 years, collecting self-reported demographics, health behaviors, socioeconomic characteristics and anthropometric measurements. We performed univariable and multivariable (adjusting for demographics and health behaviors) sex-specific Poisson's regression with robust variance, reporting adjusted prevalence ratios (PRs) and 95% confidence intervals. Results: The prevalence of obesity was 22% among males and 17% among females. According to univariable analyses, higher obesity prevalence was associated with increased age, decreased physical activity and decreased alcohol consumption in both genders. In addition, obesity was associated with refugee status and former smoking in males and with a higher healthy diet score in females. There was a clear linear decrease in obesity prevalence each step up the socioeconomic hierarchy in both genders. In the fully adjusted model, a clear inverse gradient in obesity prevalence by educational attainment was observed in females (p=0.002), while, in males, lower obesity prevalence remained significantly associated with the highest level of family-net income and educational attainment (aPR:0.48; 95% CI:0.27-0.84 and aPR:0.46; 95% CI:0.25-0.84, respectively). Occupational social class was not associated with obesity. Conclusions: This study highlights striking social inequalities in obesity in an Eastern Mediterranean population, which only recently moved from rural living to high levels of development. We recommend that public health interventions should address education - and income-related barriers, as a means of tackling health inequalities.

The effects of kinesiophobia on outcome following total knee replacement: a systematic review.

INTRODUCTION: Kinesiophobia, the fear of physical movement and activity related to injury vulnerability, has been linked to sub-optimal outcomes following total knee replacement (TKR). This systematic review has two aims: to define the relationship between kinesiophobia and functional outcomes, pain and range of motion following TKR, and to evaluate published treatments for kinesiophobia following TKR. MATERIALS AND METHODS: A primary search of electronic databases, grey literature, and trial registries was performed in March 2020. English-language studies recruiting adult primary TKR patients, using the Tampa Scale of Kinesiophobia (TSK) were included. Outcome measures were grouped into short (< 6 months), medium (6-12 months), and long term (> 12 months). Study quality was assessed using the Newcastle Ottawa Scale for cohort or case control studies, and the Cochrane Collaboration Risk of Bias tool for randomised controlled trials. RESULTS: All thirteen included papers (82 identified) showed adequately low risk of methodological bias. TSK1 (activity avoidance) correlated with WOMAC functional score at 12 months in three studies (r = 0.20 p < 0.05, R = 0.317 p = 0.001, and correlation coefficient 0.197 p = 0.005). TSK score significantly correlated with mean active range of motion (ROM) at 2 weeks [65.98 (SD = 14.51) versus 47.35 (SD = 14.48) p = 0.000], 4 weeks [88.20 (SD = 15.11) versus 57.65 (SD = 14.80) p = 0.000], and 6 months [105.33 (SD = 12.34) versus 85.53 (SD = 14.77) p = 0.000] post-operation. Three post-operative interventions improved TSK score vs control following TKR: a home-based functional exercise programme [TSK - 14.30 (SD = 0.80) versus - 2.10 (SD = 0.80) p < 0.001], an outpatient cognitive behavioural therapy (CBT) programme [TSK 27.76 (SD = 4.56) versus 36.54 (SD = 3.58)], and video-based psychological treatment [TSK 24 (SD = 5) versus 29 (SD = 5) p < 0.01]. CONCLUSIONS: Kinesiophobia negatively affects functional outcomes up until 1 year post-operatively, while active ROM is reduced up to 6 months post-procedure. Post-operative functional and psychological interventions can improve kinesiophobia following TKR.

Epidemiology of Huntington disease in Cyprus: A 20-year retrospective study.

Huntington disease (HD) is most prevalent among populations of western European descent and isolated populations where founder effects may operate. The aim of this study was to examine the epidemiology of HD in Cyprus, an island in southern Europe with extensive western European colonization in the past. All registered HD patients in the Cyprus, since 1994, were included. Detailed pedigrees and clinical information were recorded and maps, showing the geographic distribution of HD, were constructed. Requests for genetic testing were also examined. The project identified 58 clinically manifested cases of HD belonging to 19 families. The 16 families of Cypriot origin were concentrated in a confined geographical cluster in southeast Cyprus. In 2015, prevalence of symptomatic HD was 4.64/100 000 population, while incidence was 0.12/100 000 person-years. Prevalence displayed a marked increase during the past 20 years. Disease characteristics of HD patients were similar to those reported in western European populations. Lastly, the uptake of predictive and/or prenatal testing was limited. HD disease characteristics, incidence and prevalence in Cyprus were comparable to western European populations. Together with the geographical clustering observed, these results support the possibility for a relatively recent founder effect of HD in Cyprus, potentially of western European origin.

Maternal outcomes of pregnant patients after trauma: a retrospective study of the Trauma Registry of England and Wales.

INTRODUCTION: Trauma accounts for 20% of deaths in pregnant women. Injury characterisation and outcome in pregnant women following trauma is poorly described. To understand and inform optimum care of this key injury population, a study was conducted using the Trauma Audit Research Network (TARN) database. METHODS: In total, 341 pregnant and 26,774 non-pregnant female patients aged 15 to 46 years were identified for comparison from the TARN database. Mortality, cross-sectional imaging, blood product administration and EQ-5D scores were compared between the two groups. Mechanism of injury, Injury Severity Score (ISS) and mortality rate before and after the creation of regional trauma networks were reported for pregnant patients. RESULTS: Pregnancy was recorded in 1.3% (341/27,115) of included patients, with the most common cause of injury being road traffic collisions. A reduction in crude maternal mortality was observed over the course of the study period (7.3% to 2.9%). Baseline mean EQ-5D (0.47) and EQ-VAS (54.08) improved to 0.81 (p < 0.001) and 85.75 (p = 0.001), respectively, at 6 months following injury. CONCLUSION: The incidence of trauma in pregnancy is small and mortality in injured pregnant women decreased over the study period. Pregnant patients have significantly improved patient-reported outcome measures 6 months after injury although this is limited in impact because of poor response rates and outcome reporting. Construction and validation of tools aiding in outcome reporting will help considerably in understanding further gains in the care of pregnant women.

National variation in guidance for the management of pregnant women presenting with major trauma.

INTRODUCTION: The initial assessment of pregnant women presenting with significant injuries is more complicated than that of non-pregnant women because of physiological and anatomical changes, and the presence of the fetus. The aim of this study was to determine whether guidelines for the early management of severely injured pregnant women exist, which aspects of assessment/management they cover and to what extent there is national consistency. METHODS: A freedom of information request was submitted to 125 acute National Health Service trusts in England and six in Wales. The trusts were asked to confirm whether they have a guideline for the management of major trauma in pregnant women presenting to the emergency department and what the guidelines were. RESULTS: In total, 96.2% of trusts responded, of which 19% have a specific guideline and 7.9% have a generic guideline for assessing pregnant women in the emergency department, irrespective of injury severity. Of the responding trusts, 19.8% have a protocol that specifies when an obstetric trauma call should be put out by the emergency department and when a pregnant woman should be transferred to a major trauma centre for definitive management. Our results found that 69.8% routinely call obstetrics or gynaecology to the trauma call compared with 36.5% calling paediatrics. CONCLUSIONS: The heterogeneity evident across trusts necessitates the establishment of national guidelines for the assessment of pregnant women with major trauma to standardise communication and delivery of care.

The impact of salt water soaks on biophysical and molecular parameters in psoriatic epidermis equivalents.

BACKGROUND/AIMS: The exact mechanisms of action of balneophototherapy are incompletely understood. We aimed to investigate the effect of salt water soaks on ultraviolet (UV) transmission and the expression of molecular parameters of psoriasis. METHODS: We studied UV transmission and the expression of antimicrobial peptides and skin-derived antileukoproteinase (SKALP/elafin) in psoriatic epidermis equivalents which were pretreated with tap water and differently concentrated salt water solutions. Moreover, we performed in vivo phototoxicity tests in healthy subjects. RESULTS: Highly concentrated salt water soaks significantly increase UV transmission through psoriatic epidermis equivalents, in particular within the wavelength range of 305- 360 nm. In vivo tests revealed increased photosensitivity following highly concentrated salt water baths. A significant decrease in human ß-defensin-2 (hBD-2) and SKALP/elafin is observed after highly concentrated NaCl soaks. CONCLUSION: An increase in UV transmission following highly concentrated salt water soaks likely causes enhanced UV gain within the viable epidermis. Moreover, our data indicate that salt water soaks seem to influence the protein profiles of hBD-2 and SKALP/elafin.

There is no clinically important difference in the Oxford knee scores between one and two years after total knee arthroplasty: The one-year score could be used as the benchmark timepoint to assess outcome.

BACKGROUND: The aim was to assess the whether there was a clinically important change in the Oxford knee score (OKS) between one and two years after total knee arthroplasty (TKA), and to identify predictors associated with a clinically important change. METHODS: A retrospective cohort study was undertaken using an established arthroplasty database of 5857 primary TKA. Patient demographics, body mass index, social deprivation, OKS and EuroQoL five-domain (EQ-5D) score were collected preoperatively and at one and two years postoperatively. A clinically important change in the OKS was defined as ≥5 points. RESULTS: There was a 0.2 point increase in the OKS between one and two years, which was statistically significant (95% confidence interval (CI) 0.1 to 0.4, p < .0001), but not clinically important. A better preoperative OKS (p < .001) and in contrast a worse one year OKS (p < .001) were independently associated with a greater improvement from one to two years. There were 1006 (17.3%) patients that had a clinically important improvement in the OKS between one and two years. Receiver operating characteristic curve analysis showed that a one year OKS of less than 35 was a reliable predictor of a clinically important improvement between one and two years (area under the curve 0.77, 95% CI 0.76 to 0.78, p < .001). CONCLUSION: There was not a clinically important change in the OKS from one to two years after TKA when assessed as a group. However, individual patients with a one year OKS of less than 35 may demonstrate a clinically important improvement at two years. LEVEL OF EVIDENCE: Retrospective diagnostic study, Level III.

Disruption of FOXF2 as a Likely Cause of Absent Uvula in an Egyptian Family.

This study investigated the genetic basis of an unusual autosomal dominant phenotype characterized by familial absent uvula, with a short posterior border of the soft palate, abnormal tonsillar pillars, and velopharyngeal insufficiency. Cytogenetic analysis and single-nucleotide polymorphism-based linkage analysis were investigated in a 4-generation family with 8 affected individuals. Whole exome sequencing data were overlaid, and segregation analysis identified a single missense variant, p.Q433P in the FOXF2 transcription factor, that fully segregated with the phenotype. This was found to be in linkage disequilibrium with a small 6p25.3 tandem duplication affecting FOXC1 and GMDS. Notably, the copy number imbalances of this region are commonly associated with pathologies that are not present in this family. Bioinformatic predictions with luciferase reporter studies of the FOXF2 missense variant indicated a negative impact, affecting both protein stability and transcriptional activation. Foxf 2 is expressed in the posterior mouse palate, and knockout animals develop an overt cleft palate. Since mice naturally lack the structural equivalent of the uvula, we demonstrated FOXF2 expression in the developing human uvula. Decipher also records 2 individuals with hypoplastic or bifid uvulae with copy number variants affecting FOXF2. Nevertheless, given cosegregation with the 6p25.3 duplications, we cannot rule out a combined effect of these gains and the missense variant on FOXF2 function, which may account for the rare palate phenotype observed.

Serratia marcescens bacteremia after carotid endarterectomy and coronary artery bypass grafting.

Serratia Marcescens is a common, water-borne hospital colonizer. Respiratory secretions, wounds, and urine are frequently recognized areas of Serratia colonization. Serratia bacteremias usually occur nosocomially and are associated with high mortality and morbidity rates. Serratia bacteremias may be primary or secondary from an identifiable source. Hospital-acquired S marcescens bacteremias have no known source in half of the cases. We present a case of nosocomial primary S marcescens bacteremia in a surgical patient successfully treated with levofloxacin.

Direct determination of four fluoroquinolones, enoxacin, norfloxacin, ofloxacin, and ciprofloxacin, in pharmaceuticals and blood serum by HPLC.

A rapid, accurate and sensitive method has been developed for the quantitative determination of four fluoroquinolone antimicrobial agents, enoxacin, norfloxacin, ofloxacin and ciprofloxacin, with high in-vitro activity against a wide range of Gram-negative and Gram-positive organisms.A Kromasil 100 C(8) 250 mm x 4 mm, 5 microm analytical column was used with an eluting system consisting of a mixture of CH(3)CN-CH(3)OH-citric acid 0.4 mol L(-1) (7:15:78 %, v/v). Detection was performed with a variable wavelength UV-visible detector at 275 nm resulting in limits of detection: 0.02 ng per 20 microL injection for enoxacin and 0.01 ng for ofloxacin, norfloxacin and ciprofloxacin. Hydrochlorothiazide (HCT) was used as internal standard at a concentration of 2 ng microL(-1). A rectilinear relationship was observed up to 2 ng microL(-1) for enoxacin, 12 ng microL(-1) for ofloxacin, 3 ng microL(-1) for norfloxacin, and 5 ng microL(-1) for ciprofloxacin. Separation was achieved within 10 min. The statistical evaluation of the method was examined by performing intra-day (n=8) and inter-day precision assays (n=8) and was found to be satisfactory with high accuracy and precision. The method was applied to the direct determination of the four fluoroquinolones in human blood serum. Sample pretreatment involved only protein precipitation with acetonitrile. Recovery of analytes in spiked samples was 97+/-6% over the range 0.1-0.5 ng microL(-1).

Photochemistry in the isolated Photosystem II reaction-centre core complex.

The photochemistry of the isolated Photosystem II reaction-centre core from pea and the green alga Scenedesmus was examined by e.s.r. Two types of triplet spectrum were observed in addition to the spin-polarized reaction-centre triplet previously identified. The additional triplet formed on continuous illumination at 4.2 K was attributed to a monomeric phaeophytin molecule. The second triplet, which was stable in the dark at 4.2 K following illumination, was assigned to the radical pair Donor+I-. This provides evidence that an electron donor to chlorophyll P680 is present on the polypeptide D1-polypeptide D2-cytochrome b-559 core complex.
