Ethnic differences in the severity and clinical management of type 2 diabetes at time of diagnosis: A cohort study in the UK Clinical Practice Research Datalink.

AIMS: To characterize ethnic differences in the severity and clinical management of type 2 diabetes at initial diagnosis. METHODS: An observational cohort study of 179,886 people with incident type 2 diabetes between 2004 and 2017 in the Clinical Practice Research Datalink was undertaken; 63.4% of the cohort were of white ethnicity, 3.9% south Asian, and 1.6% black. Ethnic differences in clinical profile at diagnosis, consultation rates, and risk factor recording were derived from linear and logistic regression. Cox-proportional hazards regression was used to determine ethnic differences in time to initiation of therapeutic and non-therapeutic management following diagnosis. All analyses adjusted for age, sex, deprivation, and clustering by practice. RESULTS: In the 12 months prior to diagnosis, non-white groups had fewer consultations compared to white groups, but risk factor recording was better than or equivalent to white groups for 9/10 risk factors for south Asian groups and 8/10 risk factors for black groups (p < 0.002). Blood pressure, BMI, cholesterol, eGFR, and CVD risk levels were more favourable in non-white groups, and prevalence of macrovascular disease was significantly lower (p < 0.003). Time to initiation of antidiabetic treatment and first risk assessment was faster in non-white groups relative to white groups, while time to risk factor measurement and diabetes review was slower. CONCLUSIONS: We find limited evidence of systematic ethnic inequalities around the time of type 2 diabetes diagnosis. Ethnic disparities in downstream consequences may relate to genetic risk factors, or manifest later in the care pathway, potentially in relation to long-term risk factor control.

What is the evidence for interactions between filaggrin null mutations and environmental exposures in the aetiology of atopic dermatitis? A systematic review.

BACKGROUND: Epidemiological studies indicate that gene-environment interactions play a role in atopic dermatitis (AD). OBJECTIVES: To review the evidence for gene-environment interactions in AD aetiology, focusing on filaggrin (FLG) loss-of-function mutations. METHODS: A systematic search from inception to September 2018 in Embase, MEDLINE and BIOSIS was performed. Search terms included all synonyms for AD and filaggrin/FLG; any genetic or epidemiological study design using any statistical methods were included. Quality assessment using criteria modified from guidance (ROBINS-I and Human Genome Epidemiology Network) for nonrandomized and genetic studies was completed, including consideration of power. Heterogeneity of study design and analyses precluded the use of meta-analysis. RESULTS: Of 1817 papers identified, 12 studies fulfilled the inclusion criteria required and performed formal interaction testing. There was some evidence for FLG-environment interactions in six of the studies (P-value for interaction ≤ 0·05), including early-life cat ownership, older siblings, water hardness, phthalate exposure, higher urinary phthalate metabolite levels (which all increased AD risk additional to FLG null genotype) and prolonged breastfeeding (which decreased AD risk in the context of FLG null genotype). Major limitations of published studies were the low numbers of individuals (ranging from five to 94) with AD and FLG loss-of-function mutations and exposure to specific environmental factors, and variation in exposure definitions. CONCLUSIONS: Evidence on FLG-environment interactions in AD aetiology is limited. However, many of the studies lacked large enough sample sizes to assess these interactions fully. Further research is needed with larger sample sizes and clearly defined exposure assessment. Linked Comment: Park and Seo. Br J Dermatol 2020; 183:411.

Ethnic differences in urinary calcium and phosphate excretion between Gambian and British older adults.

UNLABELLED: Ethnic differences in renal calcium and phosphate excretion exist, which may depend on differences in their dietary intakes and regulatory factors. We report highly significant differences in urinary calcium and phosphate excretion between white British and Gambian adults after statistical adjustment for mineral intakes, indicating an independent effect of ethnicity. INTRODUCTION: Populations vary in their risk of age-related osteoporosis. There are racial or ethnic differences in the metabolism of the bone-forming minerals calcium (Ca) and phosphate (P), with a lower renal Ca and P excretion in African-Americans compared to white counterparts, even at similar intakes and rates of absorption. Also, Africans in The Gambia have a lower Ca excretion compared to white British subjects, groups known to differ in their dietary Ca intake. Here, we report on differences in urinary Ca and P excretion between Gambian and white British adults while allowing for known predictors, including dietary intakes. METHODS: Participants were healthy white British (n = 60) and Gambian (n = 61) men and women aged 60-75 years. Fasting blood and 2-h urine samples were collected. Markers of Ca and P metabolism were analysed. Dietary intake was assessed with country-specific methods. RESULTS: White British older adults had higher creatinine-corrected urinary Ca and P excretion (uCa/uCr, uP/uCr) and lower tubular maximum of Ca and P compared to Gambian counterparts. The predictors of urinary Ca and P differed between groups. Multiple regression analysis showed that dietary Ca and Ca/P were predictors of uCa/uCr and uP/uCr, respectively. Ethnicity remained a significant predictor of uCa/uCr and uP/uCr after adjustment for diet and other factors. CONCLUSIONS: Gambian older adults have higher renal Ca conservation than British counterparts. Dietary mineral intakes were predictors of the differences in urinary Ca and P excretion, but ethnicity remained a highly significant predictor after statistical adjustment. This suggests that ethnicity has an independent effect on renal Ca and P handling.

Surveillance of Patients with Metal-on-Metal Hip Resurfacing and Total Hip Prostheses: A Prospective Cohort Study to Investigate the Relationship Between Blood Metal Ion Levels and Implant Failure.

BACKGROUND: We designed a prospective, single-center study to assess whether blood metal ion levels could predict implant failure in patients managed with unilateral metal-on-metal hip resurfacing or total hip arthroplasty. METHODS: Five hundred and ninety-seven patients who had received unilateral Articular Surface Replacement prostheses at least twelve months earlier were recruited. Blood metal ion levels were compared between the group of patients with failed implants and the group with non-failed implants. Implant failure was defined as prostheses associated with revision, an intention to revise, or poor patient-reported hip function (Oxford Hip Score, <31 of 48). Specificity, sensitivity, area under the curve, positive and negative predictive values, and odds ratios were calculated. Logistic regression analysis was used to identify other risk factors for implant failure. RESULTS: Patients with failed arthroplasty had significantly higher blood cobalt and chromium ion levels than did patients with non-failed arthroplasty (p < 0.01). Blood cobalt ion levels were disproportionately raised in patients with failed total hip arthroplasty (8.2 µg/L) compared with patients with failed hip resurfacing (2.5 µg/L) (p = 0.018). Blood chromium ion levels were not significantly different in patients with failed total hip arthroplasty and failed hip resurfacing (p = 0.058). The maximum value of either metal ion had good discriminant ability to predict implant failure (area under the curve, 0.76). A 7-µg/L cutoff had a positive predictive value of 0.75 (95% confidence interval, 0.66 to 0.82) and a negative predictive value of 0.82 (95% confidence interval, 0.78 to 0.86). In patients managed with total hip arthroplasty, for each increase of 1 µg/L there was a 23% (p < 0.001) increase in the odds of them being in the failed group. For patients managed with hip resurfacing, the increase in odds was 5% (p < 0.001). CONCLUSIONS: Raised levels of blood metal ions were associated with failed metal-on-metal hip resurfacings and total hip arthroplasties. A threshold level of 7 µg/L had inadequate sensitivity to be used in isolation as a screening test for implant failure, but it provided nearly optimal misclassification rates. No level had a perfect positive predictive value, and so we discourage surgeons from performing revision surgery based on blood metal ion levels alone. Levels of cobalt ions were raised out of proportion to levels of chromium ions in failed total hip arthroplasty and may reflect a different mechanism for metal ion generation. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

Physical activity reduces the risk of incident type 2 diabetes in general and in abdominally lean and obese men and women: the EPIC-InterAct Study.

AIMS/HYPOTHESIS: We examined the independent and combined associations of physical activity and obesity with incident type 2 diabetes in men and women. METHODS: The InterAct case-cohort study consists of 12,403 incident type 2 diabetes cases and a randomly selected subcohort of 16,154 individuals, drawn from a total cohort of 340,234 participants with 3.99 million person-years of follow-up. Physical activity was assessed by a four-category index. Obesity was measured by BMI and waist circumference (WC). Associations between physical activity, obesity and case-ascertained incident type 2 diabetes were analysed by Cox regression after adjusting for educational level, smoking status, alcohol consumption and energy intake. In combined analyses, individuals were stratified according to physical activity level, BMI and WC. RESULTS: A one-category difference in physical activity (equivalent to approximately 460 and 365 kJ/day in men and women, respectively) was independently associated with a 13% (HR 0.87, 95% CI 0.80, 0.94) and 7% (HR 0.93, 95% CI 0.89, 0.98) relative reduction in the risk of type 2 diabetes in men and women, respectively. Lower levels of physical activity were associated with an increased risk of diabetes across all strata of BMI. Comparing inactive with active individuals, the HRs were 1.44 (95% CI 1.11, 1.87) and 1.38 (95% CI 1.17, 1.62) in abdominally lean and obese inactive men, respectively, and 1.57 (95% CI 1.19, 2.07) and 1.19 (95% CI 1.01, 1.39) in abdominally lean and obese inactive women, respectively. CONCLUSIONS/INTERPRETATION: Physical activity is associated with a reduction in the risk of developing type 2 diabetes across BMI categories in men and women, as well as in abdominally lean and obese men and women.

Design and cohort description of the InterAct Project: an examination of the interaction of genetic and lifestyle factors on the incidence of type 2 diabetes in the EPIC Study.

AIMS/HYPOTHESIS: Studying gene-lifestyle interaction may help to identify lifestyle factors that modify genetic susceptibility and uncover genetic loci exerting important subgroup effects. Adequately powered studies with prospective, unbiased, standardised assessment of key behavioural factors for gene-lifestyle studies are lacking. This case-cohort study aims to investigate how genetic and potentially modifiable lifestyle and behavioural factors, particularly diet and physical activity, interact in their influence on the risk of developing type 2 diabetes. METHODS: Incident cases of type 2 diabetes occurring in European Prospective Investigation into Cancer and Nutrition (EPIC) cohorts between 1991 and 2007 from eight of the ten EPIC countries were ascertained and verified. Prentice-weighted Cox regression and random-effects meta-analyses were used to investigate differences in diabetes incidence by age and sex. RESULTS: A total of 12,403 verified incident cases of type 2 diabetes occurred during 3.99 million person-years of follow-up of 340,234 EPIC participants eligible for InterAct. We defined a centre-stratified subcohort of 16,154 individuals for comparative analyses. Individuals with incident diabetes who were randomly selected into the subcohort (n = 778) were included as cases in the analyses. All prevalent diabetes cases were excluded from the study. InterAct cases were followed-up for an average of 6.9 years; 49.7% were men. Mean baseline age and age at diagnosis were 55.6 and 62.5 years, mean BMI and waist circumference values were 29.4 kg/m(2) and 102.7 cm in men, and 30.1 kg/m(2) and 92.8 cm in women, respectively. Risk of type 2 diabetes increased linearly with age, with an overall HR of 1.56 (95% CI 1.48-1.64) for a 10 year age difference, adjusted for sex. A male excess in the risk of incident diabetes was consistently observed across all countries, with a pooled HR of 1.51 (95% CI 1.39-1.64), adjusted for age. CONCLUSIONS/INTERPRETATION: InterAct is a large, well-powered, prospective study that will inform our understanding of the interplay between genes and lifestyle factors on the risk of type 2 diabetes development.

Mediterranean diet and type 2 diabetes risk in the European Prospective Investigation into Cancer and Nutrition (EPIC) study: the InterAct project.

OBJECTIVE: To study the association between adherence to the Mediterranean dietary pattern (MDP) and risk of developing type 2 diabetes, across European countries. RESEARCH DESIGN AND METHODS: We established a case-cohort study including 11,994 incident type 2 diabetic case subjects and a stratified subcohort of 15,798 participants selected from a total cohort of 340,234 participants with 3.99 million person-years of follow-up, from eight European cohorts participating in the European Prospective Investigation into Cancer and Nutrition (EPIC) study. The relative Mediterranean diet score (rMED) (score range 0-18) was used to assess adherence to MDP on the basis of reported consumption of nine dietary components characteristic of the Mediterranean diet. Cox proportional hazards regression, modified for the case-cohort design, was used to estimate the association between rMED and risk of type 2 diabetes, adjusting for confounders. RESULTS: The multiple adjusted hazard ratios of type 2 diabetes among individuals with medium (rMED 7-10 points) and high adherence to MDP (rMED 11-18 points) were 0.93 (95% CI 0.86-1.01) and 0.88 (0.79-0.97), respectively, compared with individuals with low adherence to MDP (0-6 points) (P for trend 0.013). The association between rMED and type 2 diabetes was attenuated in people <50 years of age, in obese participants, and when the alcohol, meat, and olive oil components were excluded from the score. CONCLUSIONS: In this large prospective study, adherence to the MDP, as defined by rMED, was associated with a small reduction in the risk of developing type 2 diabetes in this European population.

New trends in breast reconstructive surgery: "Florentine Lily" reductive mastoplasty.

BACKGROUND: To describe a mammoplasty technique that we called "Florentine Lily" because of the shape of the pre-operative drawings similarity with the symbol lily Florentine. METHODS: In a group of 190 women who underwent reductive mammoplasty, 23 women affected by severe enlarged breasts were selected. Main selection requirements were: 18-30 cm rising of the Areola-Nipple Complex (NAC). RESULTS: to obtain a functional and cosmetic result; preservation of mammary gland function; vitality of the areola-nipple complex and its sensitivity. We describe the case of 35 years old woman affected by severe enlargement of the breast and no pathologies. CONCLUSION: We didn't observe necrosis of the skin flaps and NAC in any case. In one case (rising of Nipple-Areola Complex >25 cm) NAC showed NAC 2 days post-surgery, which spontaneously resolved. Minor complications (edema and ematoma) developed in 20 cases. No infections were observed.

Compartment syndrome of the hand with acute bullous eruption due to extravasation of computed tomography contrast material.

This article presents a case of an 80-year-old woman with severe hematoma and consequently a compartmental syndrome of the hand complicated with acute bullous eruption due to extravasation of contrast material. Compartment syndrome of the hand has been linked to a number of various etiologies. Failure to adequately diagnose and treat compartment syndromes of the hand can lead to irreparable functional loss. In the majority of the cases extravasation results only in minimal swelling or erythema. However, severe skin necrosis, ulceration and compartment syndrome may occur with extravasation of large volumes. Compartment syndrome was diagnosed, and the patient underwent immediately fasciotomy. After fasciotomy we weekly followed up our patient with medications and after she regained the full use of the hand. We report this case to assess the importance of a careful evaluation of the intravenous administration site and close monitoring of the patient during contrast material injection to obtain minimal or prevent every kind of extravasation injuries.

Treatment of stable vitiligo hands by ReCell system: a preliminary report.

BACKGROUND: The aim of this report was to analyze the results obtained with the ReCell system for the surgical treatment of stable vitiligo hands. MATERIALS AND METHODS: One patient with stable vitiligo of the hands was admitted at the Department of Plastic and Reconstructive Surgery, University of Rome Tor Vergata. The patient underwent to ReCell system for the treatment of stable vitiligo hands. RESULTS: The repigmentation was assessed using the Vitiligo Area Scoring index (VASI). The extent of pigmentation was scored as excellent, good, fair, and poor depending on the percentage of the repigmentation in the previously depigmented site. The color of the repigmented area was compared with the adjacent normally pigmented area. The patient had an excellent repigmentation. CONCLUSIONS: ReCell system is a simple, safe and feasible technique. The method that uses noncultured autologous epidermal suspension is simpler, cheaper, less time consuming and does not require sophisticated laboratory facilities, when compared with methods employing cultured melanocytes.

A case of labial fusion and urinary pseudo-incontinence in an elderly woman. A surgical treatment and a review.

Labial fusion is defined as either partial or complete adherence of the labia minora (1), and also called vulvar fusion, adhesions of the labia minor or conglutination of the labia minora and sinechia of the vulva. The complete and severe labial fusion is a rare pathology with a small number of cases reported in the literature in adults. We present a case report of a postmenopausal woman who presented with voiding difficulty and incontinence and was treated by surgical division of the adhesions and immediate resolution of the urinary incontinence confirmed by multichannel urodynamic test postoperatively.

A neglected giant subcutaneous leiomyosarcoma of the shoulder: a case report.

Superficial leiomyosarcoma is an exceeding uncommon malignant tumor, which can be located either cutaneous or subcutaneous tissues. It may occur anywhere in the body, but there is a predilection for the thighs. The distinction between cutaneous or subcutaneous, increased mass size (> 5 cm) and depth are considered to have worst prognosis in terms of recurrence and metastasis. We report a rare case of an 81-year-old woman, presented with a 20-cm leiomyosarcoma of the shoulder. The patient reported that the mass was completely asymptomatic and its growth was slow. A CT study showed a lesion closely apposed to the head of the humerus and revealed no a clear relationship with the surrounding muscles. There was no regional lymphadenopathy or the evidence of metastatic disease. After tumor resection, a large skin and soft-tissue defect was remained and the repair was performed by myocutaneous rotational free flap of latissimus dorsi. The conclusion of the histological analysis was: subcutaneous leiomyosarcoma pT2--grade 1+ (NCI system). The delayed diagnosis and the surgical treatment and giant size of soft tissue leiomyosarcoma may adversely affect the final result.

Description of columellar defects and its tridimensional remedial techniques.

Columella is an important facial component and provides support and projection to the tip of the nose. Columella defects may cause significant aesthetic and functional deformities. We present our case-load of 2007: 61 patients operated in that year had been carried out and concluded. Surgical techniques for the correction of columellar defects were classified as "open tip" and "closed tip". Then, depending on the defect, it was possible to intervene on different structures. Of the 61 patients who underwent corrective surgery, only 6 (<10%) maintained or presented again, after a temporary improvement, with the columellar defect at the end of the follow-up. For all the other patients, the final outcome was more than satisfactory. A very good aesthetic result was obtained with no functional complications. In fact, nose functionality is supported by medial crura, laid one upon the other, providing considerable resistance to the columella.

Frontal sinus fractures: a review of 132 cases.

BACKGROUND: Frontal sinus fractures peculiarity is that a wrong treatment not only could it encompass functional or aesthetical problems but also more dangerous complications: the proximity of the frontal bone to the brain, on a side, and to the nasolacrimal duct, on the other side, and therefore to the nasal cavity, lead the traumatisms occurring within this region to be at high risk of infections. MATERIALS AND METHODS: We report our experience on 132 cases of frontal sinus fracture treated from 1989 to 2005 and to present the surgical techniques performed as well as to compare the complications they reported over time to the International Literature data. 101 patients (76.5%) were treated in order to reduce and contain the isolated fractures involving the frontal sinus anterior wall, the patients presenting associated fractures of the frontal sinus anterior and posterior wall were 28 (21.2%), while the cases reporting isolated fractures of the nasolacrimal duct were 3. RESULTS: Our patients underwent follow-ups from 1 to 16 years long. We subdivided the complications found in our group into infectious and functional so that the incidence of the complications related to the sites and the treatment performed according to the specific case could be better assessed. In conclusion, the infectious and functional complications found were treated with a multidisciplinary study considering the approach to the craniofacial traumatized person is subordinated to the co-existence of general and neurological conditions requiring for their resolution different approaches and times.

[A comparison between traditional mammography and digital with storage phosphors]. / Confronto tra mammografia tradizionale e digitale con fosfori a memoria.

Conventional and digital mammographic images obtained with storage phosphors were compared. The digital images were acquired with high-resolution 3rd-generation (HR III) screens and specifically adapted algorithms. The experience was made both on a phantom and in vivo. The phantom study was carried out by comparing conventional with digital radiographs acquired with: a) same kV (28) and same mAs; b) same kV (24) and same mAs; c) 28 kV with 30% mAs reduction, in digital images only. The results obtained upon counting the amount of recognizable details per image demonstrated slight loss of information in digital radiographs only when mAs was reduced by 30%. Two hundred patients were studied; they were divided into four groups according to the type of breast (medium inherent contrast or solid breast) and to exposure factors. After conventional mammography, an additional digital radiograph was performed using one of the three techniques previously employed on the phantom. Separately, 10 ductogalactographies and 10 magnification radiographs of microcalcifications were compared; the same exposure factors were used in these images too. The radiographs were viewed by three expert mammographic radiologists; contrast quality and spatial resolution were investigated and a score was given to each image on a 3-grade scale (insufficient, sufficient, good). The comparison of the mean values obtained showed higher contrast and better enhancement of nodular lesions on digital images, on which, however, the depiction of microcalcifications was worse than on conventional radiographs, especially with lower radiation doses, even though the number of detected microcalcifications was the same.

[Digital radiology with storage phosphors in cephalometric study in orthodontics]. / La radiologia digitale con fosfori a memoria nello studio cefalometrico nell'ortodonzia.

Conventional radiology is continually modified with the development of digital systems which can be used for several types of radiologic examinations. Our study was aimed at evaluating the advantages of these new technologies in the orthodontic field, where the problems associated with image quality and radiation protection are major especially in young patients; the latter goal is achievable by dramatically reducing radiation dose and by avoiding repeating the exam. In our study, we compared lateral teleradiographs of the skull for cephalometric analysis obtained using conventional and digital diagnostic methods. The preliminary results demonstrated that the two imaging techniques did not differ relative to bone structure representation, even though the digital system provided better visualization of soft tissue structures. Computed radiography also allowed a marked reduction in the number of repeats and reduced radiation dose. The current disadvantages of this imaging method are the high initial cost of the equipment, reduced work rate, and the need of frequent technical assistance.
