RESUMEN
PURPOSE: The incidence of hip fractures is increasing within the aging population. Our objective was to identify and quantify the risk factors and develop a predictive model for the in-hospital mortality among hip fracture patients older than 65 years. METHODS: This is a prospective study conducted on 331 hip fracture patients older than 65 years admitted to our hospital from 2011 to 2014. Patients' demographics, prehospitalization residential status, prefracture comorbidity data, anti-aggregant and anticoagulant medication, preoperative hemoglobin value, type of fractures, type of treatments, time to surgery, and complications were recorded. RESULTS: The average age was 83 years, 73% female, and 57% of them sustained a femoral neck fracture. In 62.8% of patients, the number of pre-fracture baseline comorbidities was ≥2. The in-hospital mortality rate was 11.4%. In multivariate analysis, age over 90 years, congestive heart failure, asthma, rheumatologic disease, lung cancer, and not taking antiaggregant medication were independently associated with in-hospital mortality. A formula and risk stratification scoring for predicting the risk for in-hospital mortality was developed. Risk-adjustment model based on these variables had acceptable accuracy for predicting in-hospital mortality (c-statistic 0.77). CONCLUSION: Advanced age, and five prefracture comorbidities have a strong association with in-hospital mortality in a hip fracture patient older than 65 years old. Our predictive model was specifically designed for the old hip fracture population. It has an accuracy similar to other risk models. The specificity, positive predictive value, and negative predictive value are high. In addition, it could discriminate a high risk patient from a low risk patient for in-hospital mortality.

OBJECTIVE: To investigate the effect of healthcare provider (HCP) type (primary vs. specialist) on glycaemic control and other treatment parameters. RESEARCH DESIGN AND METHODS: Study of Once-Daily Levemir (SOLVE(™) ) is an international, 24-week, observational study of insulin initiation in people with type 2 diabetes. RESULTS: A total of 17,374 subjects were included, comprising 4144 (23.9%) primary care subjects. Glycaemic control improved in both HCP groups from baseline to final visit [glycated haemoglobin (HbA1c) -1.2 ± 1.4% (-13.1 ± 15.3 mmol/mol) and -1.3 ± 1.6% (-14.2 ± 17.5 mmol/mol), respectively]. After adjustment for known confounders, there was no statistically significant effect of HCP group on final HbA1c [-0.04%, 95% confidence interval (CI) -0.09 to -0.01 (-0.4 mmol/mol, 95% CI -1.0-0.1 mmol/mol), p = 0.1590]. However, insulin doses at the final visit were higher in primary care patients (+0.06, 95% CI 0.06-0.07 U/kg, p < 0.0001). Logistic regression demonstrated a significant effect of HCP type (primary vs. specialist care) on hypoglycaemia risk [odds ratio (OR) 0.75, 95% CI 0.64-0.87, p = 0.0002]. Primary care physicians took more time to train patients and had more frequent contact with patients than specialists (both p < 0.0001). CONCLUSIONS: Primary care physicians and specialists achieved comparable improvements in glycaemic control following insulin initiation.

AIMS: The aim of this study was to quantify diagnostic inertia (DI) when the physician fails to diagnose hypertension and determine its associated factors. METHODS: This cross-sectional, observational study involved all patients without a diagnosis of hypertension who had their blood pressure (BP) measured at least three times during the second half of 2010 (N = 48,605). Patients with altered mean BP figures (≥ 140/90 mmHg) were considered to experience DI. Secondary variables: gender, atrial fibrillation, diabetes mellitus, dyslipidemia, cardiovascular disease, age and the physician having attended a cardiovascular training course (ESCARVAL). Associated factors were assessed by multivariate logistic regression analysis. RESULTS: Diagnostic inertia was present in 6450 patients (13.3%, 95% CI: 13.0-13.6%). Factors significantly associated with DI were: male gender (OR = 1.46, 95% CI: 1.37-1.55, p < 0.001), atrial fibrillation (OR = 0.73, 95% CI: 0.58-0.92, p = 0.007), the ESCARVAL cardiovascular course (OR = 0.88, 95% CI: 0.81-0.96, p = 0.005), diabetes mellitus (OR = 0.93, 95% CI: 0.87-0.99, p = 0.016), cardiovascular disease (OR = 0.77, 95% CI: 0.67-0.88, p < 0.001) and older age (years) (18-44âOR = 1; 45-59âOR = 12.45, 95% CI: 11.11-13.94; 60-74âOR = 18.11, 95% CI: 16.30-20.12; ≥ 75âOR = 20.43, 95% CI: 18.34-22.75; p < 0.001). The multivariate model had an area under the ROC curve of 0.81 (95% CI: 0.80-0.81, p < 0.001). CONCLUSIONS: This study will help clinical researchers differentiate between the two forms of DI (interpretation of a positive screening test and interpretation of positive diagnostic criteria). The results found here in patients with hypertension suggest that this problem is prevalent, and that a set of associated factors can explain the outcome well (AUC>0.80).

WHAT IS KNOWN AND OBJECTIVE: There are acknowledged benefits to continuing metformin when initiating insulin, but there appears to be growing concern over the role of sulphonylureas and thiazolidinediones when used in combination with insulin. This analysis investigates the effects of continuing or discontinuing oral antidiabetic drugs (OADs) following the initiation of once-daily insulin detemir. METHODS: SOLVE is a 24-week, multinational observational study of insulin detemir initiation in patients with type 2 diabetes mellitus treated with one or more OADs. RESULTS: In the total cohort (n = 17 374), there were significant improvements in HbA1c (-1·3%, 95% CI -1·34; -1·27%) and weight (-0·6 kg, 95% CI -0·65; -0·47 kg), with an increase in the incidence rate of minor hypoglycaemia (+0·256 events ppy, P < 0·001), but not severe hypoglycaemia (-0·038 events ppy, P < 0·001). Study participants had information on OAD use either prior to (n = 17 086) or during insulin initiation (n = 16 346). HbA1c reductions were significantly greater in patients continuing treatment with metformin (-1·3% vs. -1·1%, P < 0·01), thiazolidinediones (-1·3% vs. -1·0%, P < 0·01) and DPP-IV inhibitors (-1·3% vs. -0·9%, P < 0·001). Final insulin doses were significantly greater in patients discontinuing treatment with sulphonylureas (0·29 vs. 0·26 IU/kg, P < 0·001), glinides (0·28 vs. 0·26 IU/kg, P < 0·01), thiazolidinediones (0·31 vs. 0·26 IU/kg, P < 0·001) and DPP-IV inhibitors (0·35 vs. 0·29 IU/kg, P < 0·001) compared with patients continuing these respective agents. All patient subgroups had a mean weight loss irrespective of OAD continuation, apart from those continuing thiazolidinediones (+0·2 kg). The largest improvements in weight were seen following the withdrawal of sulphonylureas and thiazolidinediones (-1·1 and -1·1 kg, respectively). WHAT IS NEW AND CONCLUSION: Discontinuation (or switching) of OADs at the time of insulin initiation appears to be governed principally by concerns about hypoglycaemia and weight. HbA1c improvements were smaller in patients discontinuing OADs at the time of insulin initiation and may be associated with insufficient insulin titration.

STUDY QUESTION: What is the final hormonal milieu of pre-ovulatory follicles of low-responder (LR) patients undergoing unstimulated cycles? SUMMARY ANSWER: Neither androgen secretion nor LH was impaired in pre-ovulatory follicles of LR women. WHAT IS KNOWN ALREADY: Therapies currently used to improve ovarian response in LR women have an impact on the final hormonal follicular milieu, and these changes are believed to be partially responsible for determining the success rate in these women. Surprisingly, as far as we know, there is no report of the final hormonal profile of LR women undergoing unstimulated cycles or evidence that follicular androgen secretion in LR women is impaired. STUDY DESIGN, SIZE AND DURATION: A prospective case-control study including 94 women, 36 normal controls and 58 LR patients (19 Young ≤ 35 years LR and 39 Aged >35 years LR) from 2009 to 2011. PARTICIPANTS/MATERIALS, SETTING AND METHODS: Fifty-eight LR women were divided into two groups: Young LR (age ≤ 35; n = 19) and Aged LR (ALR; age >35; n = 39). The control group (group C) comprised 36 egg donors undergoing an unstimulated cycle in our IVF unit. Serum and follicular fluid hormonal concentrations for estradiol (E2), progesterone, testosterone and androstendione were measured. The spindle parameters of metaphase II oocytes generated from these groups were also analysed. MAIN RESULTS AND THE ROLE OF CHANCE: Pre-ovulatory follicles from LR patients had similar androgenic and LH concentrations to those observed in the control group. However, higher intrafollicular concentrations of FSH and progesterone were observed in ALR. Moreover, no differences were found for the spindle evaluation of oocytes between groups by the Oosight technology. LIMITATIONS, REASONS FOR CAUTION: The controls were younger and had a lower BMI than the LR women. The sample size available restricted statistical power. WIDER IMPLICATIONS OF THE FINDINGS: This study suggests that the problem with LR women is not the final pre-ovulatory follicular androgen concentration since this is similar to normal responders, but in the ability to respond to controlled ovarian stimulation protocols. Therefore, efforts should be focused on long-interval androgen priming to potentially increase the recruitment of small antral follicles rather than increasing the intraovarian androgen levels within the current cycle. STUDY FUNDING/COMPETING INTEREST: The present project has been supported by the R+D programme from the Generalitat Valenciana (Regional Valencian Government) IMPIVA MIDTF/2010/95. The authors have no conflict of interest to declare.

Excessive water sorption and low mechanical properties are a severe drawback in some biomedical applications of hyaluronic acid (HA). A way to improve these properties is here explored through the novel concept of nanohybrid hydrogels consisting of a HA matrix including different amounts of silica-derived species. This inorganic filler phase controls the mechanical and swelling properties of HA cross-linked matrices. Below a 2 wt % of silica in the systems, nanoparticle aggregates of tens of nanometers and silica oligomers are distributed more or less homogeneously throughout the organic matrix, without percolating. This morphology of the silica phase is accompanied by an increased swelling degree of the composite when compared with pure HA. For higher silica mass ratios in the composites the inorganic counterpart coalesces, leading to a continuous inorganic silica network interpenetrated with the organic HA network, which coexists with a dispersed phase of silica-nanoparticle aggregates. Silica oligomers originating in the exposition of the nanoparticles to reactives during the composite preparation procedure contribute to the continuity of the silica network. For these compositions, swelling is reduced three times when compared with pure HA, and a significant improvement of the mechanical properties occurs. Water-containing samples of these materials exhibited a glass transition, which pure dry HA does not. None of the compositions studied showed any cytotoxicity. Thus, the materials could be of use in tissue engineering applications where these properties of HA need to be modulated.

BACKGROUND: Delphi technique allows developing a multidisciplinary consensus to establish solutions. AIM: To identify barriers and solutions to improve control in patients with Type-2 Diabetes Mellitus (DM2). METHODS: An observational study using the 2-round Delphi technique (June-August 2011). A panel of 108 experts in DM2 from medical and nursing fields (primary care providers and specialists) from different regions completed via email a questionnaire with 41 Likert statements and 9 scores for each one. Level of agreement was assessed using measures of central tendency and dispersion. We analysed commonalities/differences between the two groups (Kappa index and McNemar chi-square). RESULTS: Response rate: 65%. Degree of agreement: 63.4% (95% CI 48.7-78.1%) in medicine, and 78.1% (95% CI 65.4-90.8) in nursing (p > 0.05). Overall level of agreement: Kappa = 0.43, (χ(2) = 2.5 p > 0.05). Regarding non-compliance with therapy, it improves with: the information to the partner/family/caregiver, patient education degree in diabetes, patient motivation and ability to share and agree on decisions with the patient. Clinical inertia improves with: motivation degree of healthcare professionals and the calculation of cardiovascular risk; and gets worse with: the shortage of time in consultation, absence of data in medical record, border high limits measurements accepted as normal readings, lack of a treatment goals, lack of teamwork (Physician/Nurse), scarcity of resources and lack of alarm systems in the electronic medical record on goals to achieve. CONCLUSION: The participants achieved an agreement in interventions in non-therapeutic compliance and clinical inertia to improve DM2 control.

BACKGROUND AND OBJECTIVES: Diabetes is a chronic disease with a high impact on both health and Quality of Life Related to Health (QLRH). To evaluate the satisfaction of treatment in patients with type 2 diabetes mellitus through the Diabetes Treatment Satisfaction Questionnaire (DTSQ) and its relationship with sociodemographic variables, with antidiabetic medication and clinical-analytical variables. MATERIALS AND METHODS: This cross-sectional study was conducted in General University Hospital of San Juan de Alicante between September 2016 and December 2017. Two hundred thirty-two patients diagnosed with type 2 diabetes mellitus at least 1 year before inclusion, treated with antidiabetic medication were included. The Spanish version of the DTSQ scale was used to measure satisfaction with treatment. Factors associated with low satisfaction were analyzed by applying the Chi-square test for qualitative variables and Student-T for quantitative variables. To estimate magnitudes of association, logistic models were adjusted. RESULTS: Two hundred thirty-two patients were included in this study. 21.5% of the patients presented low satisfaction with the treatment. Patients who presented low satisfaction with treatment were associated with medications that could cause hypoglycemia (OR: 2.872 [1.195-6.903]), HbA1c levels higher than 7% (OR: 2.260 [1.005-5.083]) and drugs administered by the route oral (OR: 2.749 [1.233-6.131]). CONCLUSIONS: Patients with type 2 diabetes mellitus who had a lower score on the DTSQ questionnaire were associated with medications that produced hypoglycaemia, and with higher levels of HbA1c higher than 7%, and those who took oral medication.

AIMS: Evaluate the safety and efficacy of once-daily insulin detemir initiated in routine clinical practice in patients with type 2 diabetes mellitus inadequately controlled with oral hypoglycaemic agents (OHAs). METHODS: This large observational study was conducted in 10 countries. Adverse event data (including hypoglycaemia) and glycaemic control were recorded before and 24 weeks following insulin initiation while patients continued routine clinical management. RESULTS: In this study, 17 374 patients (53% male) were included. Mean pre-insulin values (±s.d.) were: age 62 ± 12 years; body mass index (BMI) 29.3 ± 5.4 kg/m(2); diabetes duration 10 ± 7 years; haemoglobin A1c (HbA1c) 8.9 ± 1.6%. During the study, 27 patients experienced serious adverse drug reaction, severe hypoglycaemic events or both; and there were 31 episodes of severe hypoglycaemia in 21 patients. After 24 weeks, HbA1c was 7.5 ± 1.2% (change of -1.3%; p < 0.001) and mean weight change was -0.6 kg (confidence interval -0.7, -0.5 kg, p < 0.001). Daily insulin dose increased from 13 ± 6 U (0.16 ± 0.09 U/kg) to 22 ± 16 U (0.27 ± 0.17U/kg) by 24 weeks. Multivariate regression analysis identified several independent demographic and treatment predictors of end of study HbA1c. CONCLUSIONS: Addition of once-daily insulin detemir to patients with type 2 diabetes mellitus on OHA therapy resulted in few adverse events, significant improvements in glycaemic control, small reductions in weight and low rates of hypoglycaemia. On the basis of this study, concerns about hypoglycaemia or weight gain should not preclude initiation of basal insulin analogues in patients with poor glycaemic control on OHAs.

OBJECTIVES: To assess the results of sentinel lymph node (SLN) detection in the initial stages of vulvar cancer and the recurrences that may appear. STUDY DESIGN: 76 patients with vulvar carcinoma, Stage I and II. Between 2000 and 2010, identification of the SLN was performed with a perilesional injection of Tc99m and vital dye. Ninety sentinel lymph nodes were found. They were removed separately, and lymphadenectomy was performed depending on the involved areas. Vulvar tumour was also removed. RESULTS: 76 patients were included in the study; 20 (22.22%) out of 90 SLNs presented metastases and 70 (77.77%) did not. There were no false negatives, and the sensitivity and negative predictive value reached 100%. Thirty-six months after treatment, one patient presented recurrence with a negative SLN, and two with positive SLNs. CONCLUSION: Biopsy of the SLN is a reasonable alternative to lymphadenectomy in patients with vulvar cancer Stage I and II.

OBJECTIVE: To present an international view of the scientific production in the field of primary care in the period 1985-2004. DESIGN: Retrospective, observational study. Bibliometric analysis. LOCATION: Medline database. WebSPIRS access through version 4.3. We analysed two periods: 2000-2004 (cross-sectional) and 1985-2004 (developmental). Search based on "MeSH Major" with descriptors: Primary Care or Primary Health Care, Family Practice, Family Physicians, Nurse Practitioners, and Entry Terms associated with these. KEY MEASURES: We analysed the bibliometric indicators of production, circulation, dispersion, and visibility. RESULTS: In 2000-2004, published 20911 articles were published, 0.73% of total production. There was a growth rate (1985-2004) of 221%, which was 2.4 times more than average. Transience rate was 83.17%. The English language is predominant (88.81%) over 34 languages, with Spanish being the next (2.6%). Sixteen countries produce 95.67% of the articles. Spain occupies the 7th place. Universities (52%) are the most productive institutions. There are 1074 different journals with the 10 most productive being: Br J Gen Pract, Adv Nurse Pract, Aust Fam Physician, Fam Pract, Fam Med, BMJ, Aten Primary Health Serv J, Can Fam Physician, J Fam Pract. The proportion of trials (5.43%) in PC is similar to other disciplines and has increased by 453% (1985-2004). CONCLUSIONS: The production of Primary care is about 1% of the total scientific output, with a noticeable and higher than average growth over 20 years. The proportion of clinical trials is similar to other disciplines. Although Anglo-Saxon countries and journals are the highest producers, Spain and the journal Aten Primaria is among those highlighted.

AIM: To determine the mortality, degree of dependence, survival, and years of life lost (YLL) after first episode of stroke. DESIGN: Cohort study. LOCATION: Community based register. PARTICIPANTS: A total of 553 subjects between 15-90 years with a first episode of definitive or transitory stroke were recruited between 01/04/2006 and 31/03/2008. MEASUREMENTS: The analyses were performed with the use of time-to-event methods, according to the intention-to-treat principle. The level of dependency was assessed according to the Barthel Scale one year after stroke; YLL (1-70 years) from the mean life expectancies at birth; survival analysis by Kaplan-Meier's curves, bivariate analysis comparing the variables between patients who had survived and those who died, and Cox's multivariate. RESULTS: The mean age was 73.3 (±11.6 years. The mean time of follow-up was 29.7 ± 13,4 months, during which 26.6% of the patients died. The mean Barthel score fell by >20%, particularly among women. There was moderate or greater dependence in 41.5% (95%CI 30.6-52.8%) of the subjects. The overall accumulative probability of survival was 0.96 (95% CI 0.94-0.97) in the first month and 0.69 (95% CI 0.65-0.72) in the fourth year. The thrombolytic treatment showed a protective effect on mortality, particularly among the women. The main predictive variables were, history of recurrent cardiovascular event (RR 6.7, 95% CI 2.2-21.7) and aging (RR 1.08, 95% CI 1.01-1.2). The average YLL was 11.5/10000/year SD7.2, and higher among men. CONCLUSION: There are differences in functional outcome, mortality, and potential years of life lost by gender. A new cardiovascular event is an independent prognostic factor of survival.

BACKGROUND: Black and Latina Transgender women face systemic marginalization and harm, increasing vulnerability to social stress and poor health outcomes. These communities have limited access to resources to mobilize and create paths toward health equity. OBJECTIVES: In this paper we report on the results of a community partnership to engage Black and Latina transgender communities on the South and West Sides of Chicago and establish service priorities for collective empowerment. METHODS: The Trans Accountability Project (TAP), a steering committee of racially diverse transgender and nonbinary representatives from four partner organizations, was established and led the design, recruitment, implementation, and analysis of a community needs assessment. World café and human-centered design methods, guided two community conversations/listening sessions around four activities: the perfect provider, my dream job, safety planning, and a stake-holder reflection. RESULTS: Sixty-three participants completed three activities and envisioned innovations for 1) accessible and holistic gender-affirming health care, 2) autonomous, flexible, and community-focused jobs in the arts, nonprofit/business, and care professions, and 3) safer social interactions and spaces. Ten stakeholders attended to listen and inform their organizational and clinical practices to empower Black and Latina transgender women. CONCLUSIONS: TAP prioritized accountability, connectedness, and centering the voices of Black and Latina transgender women as a starting point to intervene upon structural marginalization. Five insights emerged and have directed TAP's focus toward employment and collective care. Although further structural change remains a priority, TAP represents a mechanism for sharing power, improving communication and collaboration, and increasing transparency across relevant Chicago community-based organizations.

Resveratrol (RSV) was known to be metabolised by the gut microbiota to dihydroresveratrol, lunularin (LUNU), and (or) 3,4'-dihydroxy-trans-stilbene (DHST). We describe here for the first time that LUNU can be further dehydroxylated, but only at the 3-position, to yield 4-hydroxydibenzyl, a novel metabolite found in human urine after RSV intake in 41 out of 59 healthy participants. In contrast, DHST was not further dehydroxylated, and thus, 4-hydroxy-trans-stilbene was not detected as a gut microbial metabolite of RSV. Faecal in vitro incubations confirmed the in vivo results.

BACKGROUND AND OBJECTIVE: Out-of-hospital medical emergency services are defined as a functional organization that performs a set of sequential human and material activities. The objective of this study was to compare the mortality of patients attended by the out-of-hospital medical emergency services in 2 neighboring Spanish regions with different models of healthcare transport assistance for emergency care. MATERIAL AND METHOD: Retrospective observational cohort study, done between June 1, 2007 and December 31, 2008 in 2 regions of Gipuzkoa, Alto Deba (AD) and Bajo Deba (BD). The study variables were age, sex and place of exposure (AD/BD), heart rate, blood pressure, initial reason for the call defined by the European Resuscitation Council, unconsciousness and digestive bleeding. 3452 subjects were analyzed. RESULTS: The risk of in situ mortality in BD was 1.31 times higher than in AD (P=.050), that of hospital mortality in BD was 0.71 times lower than in AD (P=.011) and the risk of mortality at one year between counties and the combined mortality (in situ+hospital) did not contribute significant differences. CONCLUSIONS: Mortality (in situ+in-hospital, and one year aftercare) of patients treated by the out-of-hospital emergency medical services in AD (non-medicalized healthcare transport model) was similar to that of the BD region (mixed healthcare transport model).

INTRODUCTION: Recent medical investigations suggest that HLA-G, due to its tolerogenic properties, can be used as a biomarker in the diagnosis, treatment, and prognosis of different neoplasms. This observational prospective pilot study aims at detecting sHLA-G in the serum and saliva of patients diagnosed with colorectal cancer (CRC). For this purpose, we compared the expression of sHLA-G from patients with a control sample from a healthy population. MATERIALS AND METHODS: Using the specific enzyme-linked immunosorbent assay (ELISA) method, the expression of sHLA-G in the serum and saliva samples from patients affected by CRC (n = 20) and in a control sample (n = 10) were analyzed. RESULTS: The data showed that in patients with CRC, salivary sHLA-G values were significantly higher than in the control group (18.84 U/ml versus 6.3 U/ml, p = 0.036). In addition, higher levels of sHLA-G were observed in the saliva of patients with CRC in more advanced stages, compared with patients in early stages (24.2 U/ml vs. 8.1 U/ml, p = 0.019). A significant correlation was observed between the concentration of sHLA-G in the serum and saliva of the analyzed samples (Spearman correlation 0.7, p = 0.004). CONCLUSIONS: This study demonstrates, for the first time, the possibility of detecting sHLA-G in the saliva of patients with CRC, resulting in a less invasive alternative to venipuncture. Likewise, we propose that sHLA-G could be an attractive molecular target based on its significant high levels in advanced stages.

OBJECTIVES: To evaluate three different strategies (without or with mydriasis) for community based screening for sight threatening diabetic retinopathy (STDR). DESIGN: A masked cross-sectional comparative study. SETTING: Primary care centre. PARTICIPANTS: 216 type-1 and type-2 diabetic patients (432 eyes). INTERVENTIONS: Screening for STDR was performed with the Topcon CRW6S non-mydriatic camera (NMC), compared with the grading of the seven-field standard stereoscopic photographs, 30 degrees field photographs with mydriasis as the gold standard method. Three fields were studied: Field 1 centred on the macula; field 2 centred on the disc and the macula and field 3 centred on the disc, on the macula and temporal upper to the macula all without and with mydriasis. MAIN OUTCOME MEASURES: Sensitivity and specificity of screening method and prevalence of STDR. Strategies: field 1 (macular), addition of field 2 (nasal), addition of field 3 (superior temporal) all without and with mydriasis. RESULTS: The prevalence of STDR was 14.3%. When screening without mydriasis is performed, the percentage of referred patients increases from 14% (STDR) to almost 33% because of ungradable photographs. Sensitivity of detection of STDR by NMC using single field with mydriasis was 82% (95% confidence interval 72-92%) and without mydriasis 67% (54-80%). Specificity was 99% (97-100%) for single field with mydriasis and 99% (98-100%) without mydriasis. Sensitivity of detection using two fields with mydriasis was 95% (89-100%); without mydriasis (54-80%), slightly better than single field with mydriasis (72-92%). Specificity was similar. CONCLUSIONS: Screening for STDR with NMC can be performed effectively with one non-stereoscopic retinal photograph per eye with mydriasis using tropicamide 0.5%. Screening without mydriasis increases the number of patients to be referred.

Monacolin K (MK, lovastatin), a naturally occurring statin, only exerts lipid-lowering effects in its active ß-hydroxy acid form (MKA). This activation was thought to be mediated by the gut microbiota (GM). We report here for the first time that the GM does not convert MK into MKA (a spontaneous pH-dependent conversion) but catabolises MKA. The GM might hamper the lipid-lowering effects by degrading the active metabolite MKA.

Tumors of the carotid body are uncommon neoplasms that originate in the neuroectoderm. These tumors are slow growing but well vascularized and very destructive. Between 5% and 13% of carotid body tumors are malignant, behaving aggressively at the local level, invading the adjacent lymph nodes, and resulting in remote metastases. We present the case of a 60-year-old man who was examined for pain and paresthesias in his arm. Magnetic resonance imaging showed a large tumor in the left carotid space. Histologic study of a biopsy specimen from the tumor revealed that it was a paraganglioma. Further studies to determine the extent of disease detected metastases in bone and lung, confirming the tumor's malignancy.

Facial fractures, often related to traffic accidents, assault, work-related accidents, or falls, account for a considerable number of emergencies in our hospitals and are associated with high morbidity and mortality. Multidetector computed tomography (MDCT) is the imaging technique of choice in this scenario because it is widely available, fast, and useful for characterizing facial fractures and associated complications, including those located in the head. For all these reasons, MDCT is fundamental in the clinical management of these patients and in planning surgery. This paper describes the radiological anatomy of the facial region, underlining the importance of the facial buttresses, and it indicates the key points necessary for carrying out a structured approach and elaborating the corresponding radiologic report.
