RESUMEN
BACKGROUND: This publication represents a scheduled update of the 2019 guidelines of the International Working Group of the Diabetic Foot (IWGDF) addressing the use of systems to classify foot ulcers in people with diabetes in routine clinical practice. The guidelines are based on a systematic review of the available literature that identified 28 classifications addressed in 149 articles and, subsequently, expert opinion using the GRADE methodology. METHODS: First, we have developed a list of classification systems considered as being potentially adequate for use in a clinical setting, through the summary of judgements for diagnostic tests, focussing on the usability, accuracy and reliability of each system to predict ulcer-related complications as well as use of resources. Second, we have determined, following group debate and consensus, which of them should be used in specific clinical scenarios. Following this process, in a person with diabetes and a foot ulcer we recommend: (a) for communication among healthcare professionals: to use the SINBAD (Site, Ischaemia, Bacterial infection, Area and Depth) system (first option) or consider using WIfI (Wound, Ischaemia, foot Infection) system (alternative option, when the required equipment and level of expertise is available and it is considered feasible) and in each case the individual variables that compose the systems should be described rather than a total score; (b) for predicting the outcome of an ulcer in a specific individual: no existing system could be recommended; (c) for characterising a person with an infected ulcer: the use of the IDSA/IWGDF classification (first option) or consider using the WIfI system (alternative option, when the required equipment and level of expertise is available and it is considered as feasible); (d) for characterising a person with peripheral artery disease: consider using the WIfI system as a means to stratify healing likelihood and amputation risk; (e) for the audit of outcome(s) of populations: the use of the SINBAD score. CONCLUSIONS: For all recommendations made using GRADE, the certainty of evidence was judged, at best, as being low. Nevertheless, based on the rational application of current data this approach allowed the proposal of recommendations, which are likely to have clinical utility.

BACKGROUND: Classification and scoring systems can help both clinical management and audit the outcomes of routine care. AIM: This study aimed to assess published systems used to characterise ulcers in people with diabetes to determine which should be recommended to (a) aid communication between health professionals, (b) predict clinical outcome of individual ulcers, (c) characterise people with infection and/or peripheral arterial disease, and (d) audit to compare outcomes in different populations. This systematic review is part of the process of developing the 2023 guidelines to classify foot ulcers from the International Working Group on Diabetic Foot. METHODS: We searched PubMed, Scopus and Web of Science for articles published up to December 2021 which evaluated the association, accuracy or reliability of systems used to classify ulcers in people with diabetes. Published classifications had to have been validated in populations of >80% of people with diabetes and a foot ulcer. RESULTS: We found 28 systems addressed in 149 studies. Overall, the certainty of the evidence for each classification was low or very low, with 19 (68%) of the classifications being assessed by ≤ 3 studies. The most frequently validated system was the one from Meggitt-Wagner, but the articles validating this system focused mainly on the association between the different grades and amputation. Clinical outcomes were not standardized but included ulcer-free survival, ulcer healing, hospitalisation, limb amputation, mortality, and cost. CONCLUSION: Despite the limitations, this systematic review provided sufficient evidence to support recommendations on the use of six particular systems in specific clinical scenarios.

Grazing lands play a significant role in global carbon (C) dynamics, holding substantial soil organic carbon (SOC) stocks. However, historical mismanagement (e.g., overgrazing and land-use change) has led to substantial SOC losses. Regenerative practices, such as adaptive multi-paddock (AMP) grazing, offer a promising avenue to improve soil health and help combat climate change by increasing SOC accrual, both in its particulate (POC) and mineral-associated (MAOC) organic C components. Because adaptive grazing patterns emerge from the combination of different levers such as frequency, intensity, and timing of grazing, studying AMP grazing management in experimental trials and representing it in models remains challenging. Existing ecosystem models lack the capacity to predict how different adaptive grazing levers affect SOC storage and its distribution between POC and MAOC and along the soil profile accurately. Therefore, they cannot adequately assist decision-makers in effectively optimizing adaptive practices based on SOC outcomes. Here, we address this critical gap by developing version 2.34 of the MEMS 2 model. This version advances the previous by incorporating perennial grass growth and grazing submodules to simulate grass green-up and dormancy, reserve organ dynamics, the influence of standing dead plant mass on new plant growth, grass and supplemental feed consumption by animals, and their feces and urine input to soil. Using data from grazing experiments in the southeastern United States and experimental SOC data from two conventional and three AMP grazing sites in Mississippi, we tested the capacity of MEMS 2.34 to simulate grass forage production, total SOC, POC, and MAOC dynamics to 1-m depth. Further, we manipulated grazing management levers, i.e., timing, intensity, and frequency, to do a sensitivity analysis of their effects on SOC dynamics in the long term. Our findings indicate that the model can represent bahiagrass forage production (BIAS = 9.51 g C m-2, RRMSE = 0.27, RMSE = 65.57 g C m-2, R2 = 0.72) and accurately captured the dynamics of SOC fractions across sites and depths (0-15 cm: RRMSE = 0.05; 15-100 cm: RRMSE = 1.08-2.07), aligning with patterns observed in the measured data. The model best captured SOC and MAOC stocks across AMP sites in the 0-15 cm layer, while POC was best predicted at-depth. Otherwise, the model tended to overestimate SOC and MAOC below 15 cm, and POC in the topsoil. Our simulations indicate that grazing frequency and intensity were key levers for enhancing SOC stocks compared to the current management baseline, with decreasing grazing intensity yielding the highest SOC after 50 years (63.7-65.9 Mg C ha-1). By enhancing our understanding of the effects of adaptive grazing management on SOC pools in the southeastern U.S., MEMS 2.34 offers a valuable tool for researchers, producers, and policymakers to make AMP grazing management decisions based on potential SOC outcomes.

Despite speculation regarding the role of collateral consequences of sexual offender policies in psychosocial and criminogenic outcomes, there has been no empirical analysis in the extant literature examining these links. Lack of conceptual underpinnings and no psychometrically valid measure of collateral consequences has limited study in this area. A systematic literature review was conducted to assess the state of measurement in terms of conceptual and operational definitions, populations sampled, domains assessed, items used, and scale properties reported. Nineteen studies met inclusion criteria. Themes emerged regarding commonly assessed collateral consequences, the misconnect between legal and psychological conceptualizations of collateral consequences, the division between external (i.e., social) and internal (i.e., affective) collateral consequences, as well as a trend toward emphasizing the psychological damages (in addition to discrete experiences of loss) associated with a sexual offense. Findings are discussed, and a unifying definition of collateral consequences is proposed to guide future scale development.

Collateral consequences faced by individuals convicted of a sexual offense have been widely referenced in the literature. There is yet to be a systematic examination of collateral consequences affecting individuals, however, due to measurement inconsistencies and the absence of a psychometrically validated instrument. The current study developed and validated a measure of collateral consequences faced by individuals convicted of a sexual offense. Specifically, this study investigated (a) the underlying factor structure of collateral consequences commonly endorsed by individuals convicted of a sexual offense through Exploratory Factor Analysis (EFA) procedures and (b) reliability and validity indicators of the aforementioned scale. Participants were 218 individuals convicted of and registered for a sexual offense in the state of Texas. Study measures included a pool of 66 collateral consequences items in addition to psychological self-report instruments addressing hopelessness, shame, social well-being, and discrimination. EFA results revealed a two-dimensional construct representing collateral consequences affecting areas of social and psychological well-being. The current measure demonstrated adequate reliability and validity. Limitations and future directions of findings are addressed.

There is an urgent need for interventions that improve healing time, prevent amputations and recurrent ulceration in patients with diabetes-related foot wounds. In this randomised, open-label trial, participants were randomised to receive an application of non-cultured autologous skin cells ("spray-on" skin; ReCell) or standard care interventions for large (>6 cm2 ), adequately vascularised wounds. The primary outcome was complete healing at 6 months, determined by assessors blinded to the intervention. Forty-nine eligible foot wounds in 45 participants were randomised. An evaluable primary outcome was available for all wounds. The median (interquartile range) wound area at baseline was 11.4 (8.8-17.6) cm2 . A total of 32 (65.3%) index wounds were completely healed at 6 months, including 16 of 24 (66.7%) in the spray-on skin group and 16 of 25 (64.0%) in the standard care group (unadjusted OR [95% CI]: 1.13 (0.35-3.65), P = .845). Lower body mass index (P = .002) and non-plantar wounds (P = .009) were the only patient- or wound-related factors associated with complete healing at 6 months. Spray-on skin resulted in high rates of complete healing at 6 months in patients with large diabetes-related foot wounds, but was not significantly better than standard care (Australian New Zealand Clinical Trials Registry: ACTRN12618000511235).

The ease of direct-acting antiviral (DAA) medications for hepatitis C virus (HCV) has provided an opportunity to decentralize HCV treatment into community settings. However, the role of non-specialist clinicians in community-based pathways has received scant attention to date. This study examined barriers and enablers to expanding the role of general practitioners (GPs) in HCV treatment provision, using simple behaviour change theory as a conceptual framework. A maximum variation sample of 22 HCV treatment providers, GPs and HCV support workers participated in semi-structured interviews. Data were inductively coded, and the resulting codes deductively mapped into three principal components of behaviour change: capability, opportunity and motivation (COM-B). By this process, a number of provider- and systemic-level barriers and enablers were identified. Key barriers included the pre-treatment assessment of liver fibrosis, GP capacity and the 'speciality' of HCV care. Enablers included the simplicity of the drugs, existing GP/patient relationships and the provision of holistic care. In addition to these specific factors, the data also exposed an overarching provider understanding of 'HCV treatment' as triumvirate in nature, incorporating the assessment of liver fibrosis, the provision of holistic support and the treatment of disease. This understanding imposes a further fundamental barrier to GP-led treatment as each of these three components needs to be individually addressed. To enable sustainable models of HCV treatment provision by GPs, a pragmatic re-examination of the 'HCV treatment triumvirate' is required, and a paradigm shift from the 'refer and treat' status quo.

The use of telephone and/or video consultation in routine management of acute diabetes-related foot disease (DFD) before the coronavirus disease 2019 (COVID-19) pandemic at a tertiary hospital is unprecedented. In March 2020, the Diabetes Feet Australia (DFA) released a national guideline to inform DFD management during the COVID-19 pandemic. The present study aimed to describe the adherence to the DFA guideline of managing acute DFD using telephone and/or video consultation at a Western Australian tertiary hospital during this period. We found >80% adherence rate to the DFA guideline and the management of active DFD using telephone and/or video consultations was feasible and acceptable in carefully selected patients.

OBJECTIVES: A randomized controlled trial was conducted to test the hypothesis that povidone-iodine (PVI) irrigation versus no irrigation (NI) reduces postoperative intra-abdominal abscess (IAA) in children with perforated appendicitis. METHODS: A 100 patient pilot randomized controlled trial was conducted. Consecutive patients with acute perforated appendicitis were randomized (1:1) to PVI or NI from April 2016 to March 2017 and followed for 1 year. Patients and postoperative providers were blinded to allocation. The primary endpoint was 30-day image-confirmed IAA. Secondary outcomes included initial and total 30-day length of stay (LOS), emergency department (ED) visits, and readmissions. Intention-to-treat analyses were performed to estimate the probability of clinical benefit using Bayesian regression models (an optimistic prior for the primary outcome and neutral priors for secondary outcomes). Frequentist statistics were also used. RESULTS: Baseline characteristics were similar between treatment arms. The PVI arm had 12% postoperative IAA versus 16% in the NI arm (relative risk 0.72, 95% credible interval 0.38-1.23). Bayesian analysis estimates 89% probability that PVI reduces IAA. High probability of benefit was seen in all secondary outcomes for the PVI arm: fewer ED visits and readmissions, and shorter initial and total 30-day LOS. The probability of benefit in reduction of total 30-day LOS in PVI patients was 96% and was significant (P = 0.05) on frequentist analysis. CONCLUSIONS: PVI irrigation for perforated appendicitis in children demonstrated a strong probability of reduction in postoperative IAA with a high probability of decreased LOS. With the favorable probability of benefit in all outcomes, this pilot study serves as evidence to continue a definitive trial.

BACKGROUND: The aim of the study was to determine whether racial or ethnic and insurance disparities exist in pre- and post-operative length of stay (LOS) in patients with hypertrophic pyloric stenosis (HPS). MATERIALS AND METHODS: The Healthcare Cost and Utilization Project Kid's Inpatient Database database (years 2006, 2009, and 2012) was analyzed for patients aged <1 y with HPS with a primary procedure of pyloromyotomy. Multivariate logistic regression was performed to determine the association between race or ethnicity and insurance status with the primary outcomes of prolonged pre- and post-operative LOS (defined as >1 d). Odds ratios (ORs) and 95% confidence intervals (CIs) were tabulated using SPSS v24. RESULTS: A total of 13,706 cases were identified: 8503 (62%) non-Hispanic whites, 3143 (23%) Hispanics, 1007 (7%) non-Hispanic blacks (NHB), and 1053 (8%) non-Hispanic other race or ethnicity. NHB and Hispanics were 45% and 37%, respectively, more likely to have prolonged preoperative LOS compared with non-Hispanic whites (OR = 1.45, 95% CI: 1.19-1.77; OR = 1.37, 95% CI: 1.18-1.60, respectively). Children with public insurance had 21% increased odds of increased preoperative LOS (OR = 1.21, 95% CI: 1.06-1.38). All minority groups had increased odds of postoperative LOS (NHB OR 1.36, 95% CI: 1.17-1.54; Hispanic OR 1.14, 95% CI: 1.03-1.26; NHO OR 1.31, 95% CI: 1.15-1.51). CONCLUSIONS: We conclude that NHB, Hispanics, and other race or ethnicity were more likely to have prolonged pre- and post-operative LOS. In addition, children with public insurance were more likely to have prolonged preoperative LOS. Further work is needed to better characterize and eliminate disparities in the management and outcomes of children with HPS.

Among 125 inpatients with diabetic foot infections managed by a multidisciplinary foot ulcer unit, knowledge of methicillin-resistant Staphylococcus aureus colonisation status assisted decision-making to prescribe appropriately or with-hold empiric anti-methicillin-resistant Staphylococcus aureus therapy. Despite adherence to national guidelines, apparent overuse of anti-pseudomonal therapy was frequent, providing potential antimicrobial stewardship opportunities.

The current study explored narrative roles among individuals convicted of a sexual offense. Narrative roles in a criminal context are defined as specific personal accounts utilized by offenders to justify illegal behavior. The chosen theoretical framework recognized four primary offender roles: Revengeful Mission/Romantic Quest, Professional, Victim, and Tragic Hero. A total of 23 interviews were conducted with individuals convicted of a sexual offense (n = 11 contact, n = 12 noncontact) to explore and compare narrative roles between contact and noncontact offenders. Interviews were conducted using a phenomenological approach and coded via Framework Analysis, a qualitative data analytic method. Findings revealed a general pattern of narrative themes among offenders, along with a tendency for contact offenders to endorse Revengeful Mission/Romantic Quest narrative roles and noncontact offenders to endorse Tragic Hero narrative roles. Findings suggest that incorporating narrative roles into conceptualization and treatment of sexual offenders may help with tailoring treatments more effectively.

Given the increased trend in substance use patterns among Latina adolescents in recent years, the need for research that identifies gender-specific and culturally relevant protective factors is essential in tailoring interventions. The current study examined the links between marianismo gender role attitudes, ethnic identity, and substance use abstinence among 277 low-income Mexican American early adolescent girls. Mental health was also examined as a potential moderator in these links. Results of linear regression analysis revealed that familismo, virtuous/chaste, and spiritual marianismo gender role attitudes were predictive of stronger ethnic identity; conversely, self-silencing marianismo attitudes were predictive of weaker ethnic identity. Second, results of hierarchical logistic regressions revealed that both virtuous/chaste marianismo gender role attitudes and mental health (low rates of psychological distress) were inversely linked with substance use; furthermore, they had a combined link that was related to even lower rates of substance use among participants. However, ethnic identity did not have a direct or moderating effect on substance use. Findings suggest that the promotion of positive components of marianismo and mental health may have a protective effect against early substance use in Mexican American early adolescent girls.

BACKGROUND: Electronic hospital variance reporting systems used to report near misses and adverse events are plagued by underreporting. The purpose of this study is to prospectively evaluate directly observed variances that occur in our pediatric operating room and to correlate these with the two established variance reporting systems in our hospital. MATERIALS AND METHODS: Trained individuals directly observed pediatric perioperative patient care for 6 wk to identify near misses and adverse events. These direct observations were compared to the established handwritten perioperative variance cards and the electronic hospital variance reporting system. All observations were analyzed and categorized into an additional six safety domains and five variance categories. The chi-square test was used, and P-values < 0.05 were considered statistically significant. RESULTS: Out of 830 surgical cases, 211 were audited by the safety observers. During this period, 137 (64%) near misses were identified by direct observation, while 57 (7%) handwritten and 8 (1%) electronic variance were reported. Only 1 of 137 observed events was reported in the handwritten variance system. Five directly observed adverse events were not reported in either of the two variance reporting systems. Safety observers were more likely to recognize time-out and equipment variances (P < 0.001). Both variance reporting systems and direct observation identified numerous policy and process issues. CONCLUSIONS: Despite multiple reporting systems, near misses and adverse events remain underreported. Identifying near misses may help address system and process issues before an adverse event occurs. Efforts need to be made to lessen barriers to reporting in order to improve patient safety.

BACKGROUND: Staging retroperitoneal lymph node dissection (RPLND) for paratesticular rhabdomyosarcoma (RMS) is recommended for all patients aged ≥10 y. The purpose of this study was to evaluate adherence with surgical resection guidelines for RPLND in patients with paratesticular RMS as a measure for surgical quality. MATERIALS AND METHODS: All patients with paratesticular RMS were identified in the Surveillance, Epidemiology, and End Results database from 1973 to 2012. Patients were divided into two eras to reflect before (1973-2002) and after (2003-2012) the release and dissemination of the 2001 surgical guidelines for staging ipsilateral RPLND in all patients aged ≥10 y with paratesticular RMS. Survival outcomes associated with lymph node dissection were calculated using the Kaplan-Meier method and Cox proportional hazards analysis. RESULTS: Two hundred thirty-five patients with paratesticular RMS were identified and included in the study, among whom 111 were adolescents aged 10-20. RPLND did not significantly increase after 2003 among adolescents (45%-61%, P = 0.09). The benefit of RPLND on improved 5-y overall survival was evident among adolescents (92% versus 64%, P = 0.003). Adjusting for histology, age, stage at diagnosis, and race/ethnicity, RPLND was associated with improved overall survival among patients aged ≥10 y (hazard ratio 0.37, 95% confidence interval 0.17-0.83). CONCLUSIONS: Despite surgical guidelines recommending RPLND in pediatric patients aged ≥10 y, nearly one-third of adolescent patients did not undergo RPLND. These findings are disturbing considering the survival benefit associated with RPLND among adolescent patients and indicate an opportunity for improvement in surgical quality.

An examination of cultural protective factors that foster substance use abstinence among low-income, early adolescent, African American girls may be helpful in understanding how to promote resilience and reduce negative health outcomes. This study examined the relations between Africentric cultural values, ethnic identity, and substance use abstinence among 196 low-income African American early adolescent girls (age 11-14 years). Results of logistic regressions revealed that Africentric values were negatively linked to cigarette and alcohol abstinence. Results also showed a significant positive interaction between Africentric cultural values and ethnic identity exploration that contributed to increased cigarette and alcohol abstinence. Implications for research and practice with African American early adolescent girls are discussed.
RESUMEN
The purpose of our study was to evaluate surgical enteric access in pediatric cancer patients to determine factors associated with postoperative complications. We performed a single-institution retrospective review of all patients below 21 years old with a primary cancer diagnosis who underwent surgical procedures for enteral access between 2004 and 2014. Multivariate logistic regression was performed to determine independent predictors of postoperative complications. During the study period, 122 patients had surgically placed feeding tubes, of whom 58% developed ≥1 complication(s) and 16% experienced a major complication. No single factor was significantly associated with developing any complication or major complication. Several trends were noted including increased complications associated with jejunostomy tubes, percutaneous endoscopic gastrostomy tubes, and abdominal radiation. Surgically placed enteric access in pediatric and adolescent cancer patients is associated with an extremely high complication rate emphasizing the importance of careful evaluation of these patients before embarking on surgical feeding access. Future work should evaluate mechanisms to decrease complications and/or explore alternative methods to provide supplemental nutrition in children and adolescents with cancer.

OBJECTIVES: This study examined the relations between familial ethnic socialization and ethnic identity development in 438 Mexican-origin (n = 242 boys and n = 196 girls) preadolescents. In addition, machismo and marianismo gender role attitudes were examined as potential mediators in this link. METHOD: Confirmatory factor analyses (CFA) of the Familial Ethnic Socialization Scale (FES), Machismo Measure (MM), Marianismo Beliefs Scale (MBS), and the Ethnic Identity Brief Scale (EISB) were conducted to test the factor structure with a preadolescent Mexican-origin sample. Separate path analyses of analytic models were then performed on boys and girls. RESULTS: Results of the CFAs for survey measures revealed that for the FES, a 1-factor version indicated acceptable fit; for the MM, the original 2-factor structure indicated acceptable model fit; for the MBS, a revised 3-factor version indicated acceptable model fit; and, for the EISB, the affirmation and resolution dimensions showed acceptable fit. Among boys, FES was significantly and positively linked to caballerismo, and EISB affirmation and resolution; furthermore, the links between FES and EISB affirmation and resolution were indirectly connected by caballerismo. In addition, traditional machismo was negatively linked to EISB affirmation, and caballerismo was positively linked to EISB affirmation and resolution. Among girls, FES was significantly and positively related to the MBS-virtuous/chaste pillar, and EISB affirmation and resolution. The MBS-subordinate to others pillar was negatively linked to EISB affirmation. CONCLUSIONS: This study underscores the importance of FES and positive gender role attitudes in the link to ethnic identity development among Mexican-origin preadolescents. (PsycINFO Database Record

OBJECTIVE: To identify health disparities in pediatric patients with melanoma that affect disease presentation and outcome. STUDY DESIGN: This was a retrospective cohort study of all persons aged ≤18 years diagnosed with melanoma and enrolled in the Texas Cancer Registry between 1995 and 2009. Socioeconomic status (SES) and driving distance to the nearest pediatric cancer treatment center were calculated for each patient. Logistic regression was used to determine factors associated with advanced-stage disease. Life table methods and Cox regression were used to estimate survival probability and hazard ratios. RESULTS: A total of 185 adolescents (age >10 years) and 50 young children (age ≤10 years) were identified. Hispanics (n = 27; 12%) were 3 times more likely than non-Hispanic whites (n = 177; 75%) to present with advanced disease (OR, 3.8; 95% CI, 1.7-8.8). Young children were twice as likely as adolescents to present with advanced disease (OR, 2.2; 95% CI, 1.1-4.3). Distance to treatment center and SES did not affect stage of disease at presentation. Hispanics and those in the lowest SES quartile had a significantly higher mortality risk (hazard ratios, 3.0 [95% CI, 1.2-7.8] and 4.3 [95% CI, 1.4-13.9], respectively). In the adjusted survival model, only advanced disease was predictive of mortality (P < .001). CONCLUSION: Hispanics and young children with melanoma are more likely to present with advanced disease, and advanced disease is the single most important predictor of survival. Heightened awareness among physicians is needed to facilitate early detection of melanoma within these groups.

BACKGROUND: Because published studies have usually involved imprecise assays and selected patients with limited additional data and follow-up, the consequences of a low serum testosterone in diabetes are unclear. This study assessed the prevalence, associates and prognosis of a low testosterone in community-dwelling men with type 2 diabetes. DESIGN: Longitudinal observational study. PATIENTS: 788 men (mean ± SD age: 65·8 ± 11·3 years) followed for 4·0 ± 1·1 years. MEASUREMENTS: Serum testosterone, SHBG, erectile dysfunction (ED; Sexual Health Inventory for Men score <22), anaemia (haemoglobin <130 g/l), all-cause mortality. RESULTS: The mean ± SD total serum testosterone by liquid chromatography/mass spectrometry was 13·1 ± 5·9 nmol/l (30·6% <10 nmol/l). Most men with a total testosterone <10 nmol/l (67·0%) had a normal/low serum LH. Serum testosterone was independently associated with anaemia (P < 0·001), but not ED (P = 0·80), in logistic regression models. The optimal cut-point (Youden Index) for anaemia was 9·8 nmol/l (sensitivity 53·6%, specificity 75·4%). During the follow-up, 102 men (12·9%) died. There was a U-shaped relationship between total serum testosterone quintiles and death (P = 0·003, log rank test). The middle quintile (>11·1 to ≤13·7 nmol/l) had the lowest risk and there was a 78% increased risk for highest (>16·9 nmol/l) vs lowest (≤8·6 nmol/l) quintile in Cox proportional hazards modelling (P = 0·036). Free serum testosterone and SHBG quintiles were not associated with death. CONCLUSIONS: These data provide some support for the general conventional serum testosterone <10 nmol/l cut-point in identifying an increased risk of anaemia and the subsequent death in men with type 2 diabetes, but indicate that high-normal levels are also an adverse prognostic indicator.
