RESUMEN

BACKGROUND AND OBJECTIVES: The International Haemovigilance Network's ISTARE is an online database for surveillance of all adverse reactions (ARs) and adverse events (AEs) associated with donation of blood and transfusion of blood components, irrespective of severity or the harm caused. ISTARE aims to unify the collection and sharing of information with a view to harmonizing best practices for haemovigilance systems around the world. MATERIALS AND METHODS: Adverse reactionss and adverse events are recorded by blood component, type of reaction, severity and imputability to transfusion, using internationally agreed standard definitions. RESULTS: From 2006 to 2012, 125 national sets of annual aggregated data were received from 25 countries, covering 132.8 million blood components issued. The incidence of all ARs was 77.5 per 100 000 components issued, of which 25% were severe (19.1 per 100 000). Of 349 deaths (0.26 per 100 000), 58% were due to the three ARs related to the respiratory system: transfusion-associated circulatory overload (TACO, 27%), transfusion-associated acute lung injury (TRALI, 19%) and transfusion-associated dyspnoea (TAD, 12%). Cumulatively, 594 477 donor complications were reported (rate 660 per 100 000), of which 2.9% were severe. CONCLUSIONS: ISTARE is a well-established surveillance tool offering important contributions to international efforts to maximize transfusion safety.

RESUMEN

Standard definitions of donor reactions allow each blood establishment to monitor donor adverse events and compare with other organizations to develop best practices. The ISBT Haemovigilance Working Party leads a multi-organizational effort to update the 2008 ISBT standard for surveillance of complications related to blood donation. Revised definitions have been developed and endorsed by the ISBT, AABB, International Haemovigilance Network (IHN) and other international organizations.

RESUMEN

WHAT IS KNOWN AND OBJECTIVE: The risk of dosage Prescription Medication Error (PME) among manually written prescriptions within 'mixed' prescribing system (computerized physician order entry (CPOE) + manual prescriptions) has not been previously assessed in neonatology. This study aimed to evaluate the rate of dosage PME related to manual prescriptions in the high-risk population of very preterm infants (GA < 33 weeks) in a mixed prescription system. METHODS: The study was based on a retrospective review of a random sample of manual daily prescriptions in two neonatal intensive care units (NICU) A and B, located in different French University hospitals (Dijon and La Reunion island). Daily prescription was defined as the set of all drugs manually prescribed on a single day for one patient. Dosage error was defined as a deviation of at least ±10% from the weight-appropriate recommended dose. RESULTS AND DISCUSSION: The analyses were based on the assessment of 676 manually prescribed drugs from NICU A (58 different drugs from 93 newborns and 240 daily prescriptions) and 354 manually prescribed drugs from NICU B (73 different drugs from 131 newborns and 241 daily prescriptions). The dosage error rate per 100 manually prescribed drugs was similar in both NICU: 3·8% (95% CI: 2·5-5·6%) in NICU A and 3·1% (95% CI: 1·6-5·5%) in NICU B (P = 0·54). Among all the 37 identified dosage errors, the over-dosing was almost as frequent as the under-dosing (17 and 20 errors, respectively). Potentially severe dosage errors occurred in a total of seven drug prescriptions. None of the dosage PME was recorded in the corresponding medical files and information on clinical outcome was not sufficient to identify clinical conditions related to dosage PME. Overall, 46·8% of manually prescribed drugs were off label or unlicensed, with no significant differences between prescriptions with or without dosage error. The risk of a dosage PME increased significantly if the drug was included in the CPOE system but was manually prescribed (OR = 3·3; 95% CI: 1·6-7·0, P < 0·001). WHAT IS NEW AND CONCLUSION: The presence of dosage PME in the manual prescriptions written within mixed prescription systems suggests that manual prescriptions should be totally avoided in neonatal units.

RESUMEN

Canada now allows donations from men who had sex with men (MSM) if their last sexual contact with a man was more than 5 years ago. We modelled the impact of this policy on supply and safety. Approximately 4500 new donors will be added and assuming compliance to the new policy remains unchanged, the worst-case scenario predicts the introduction of one HIV-contaminated unit in the inventory every 1072 years. This change will entail negligible additional HIV risk to recipients. A five-year deferral will also protect recipients against the theoretical concern that MSM may represent a group at higher risk of sexually transmitted, emerging blood borne pathogens.

RESUMEN

RATIONALE: Xanthomatosis associated with monoclonal gammopathy includes hyperlipidaemic xanthoma (HX), normolipidaemic xanthoma (NX) and necrobiotic xanthogranuloma (NXG). All three pathologies are characterized by skin or visceral lesions related to cholesterol accumulation, monoclonal immunoglobulin (MIg) and hypocomplementemia. The pathophysiology underlying NXG remains unknown although the involvement of MIg is suspected. OBJECTIVE: To provide further insights into the pathophysiology of NXG, we evaluated the plasma lipid phenotype, mechanisms involved in cellular cholesterol accumulation and role of MIg in an analysis of blood and plasma markers of inflammation in 16 patients with xanthomatosis [NXG (n = 8) and NX (n = 8)] associated with monoclonal IgG relative to the relevant controls. RESULTS: The lipid profile of patients with NXG was characterized by a low HDL-C phenotype and an abnormal distribution of HDL particles. Sera from patients with NXG induced cholesterol accumulation in human macrophages. This accumulation was due in part to a significant reduction in the HDL capacity to promote cholesterol efflux from macrophages, which was not found in the case of NX. The MIg of NXG and NX patients was tested positively by ELISA to recognize a large spectrum of lipoproteins. High plasma levels of pro-inflammatory cytokines (TNFα and IL-6), soluble cytokine receptors (sIL-6R, sTNFRI and sTNFRII), adhesion molecules (VCAM-1 and ICAM-1) and chemokines (MCP-1, IL-8 and MIP-1α) were observed in both patients with NXG and NX, revealing a specific xanthoma inflammatory signature which was inversely correlated with plasma levels of anti-inflammatory HDL. However, patients with NXG were distinguished by elevated levels of IL-15 and a marked increase in the rate of intermediate CD14++CD16+ monocytes. CONCLUSION: This study revealed that NXG is characterized by impaired macrophage lipid homeostasis associated with a systemic inflammatory profile that may result from the interaction of MIg and lipoproteins.

RESUMEN

AIMS: Statin treatment may impair glucose homeostasis and increase the risk of new-onset diabetes mellitus, although this may depend on the statin, dose and patient population. We evaluated the effects of pitavastatin 4 mg/day on glucose homeostasis in patients with metabolic syndrome in the CAPITAIN trial. Findings were validated in a subset of patients enrolled in PREVAIL-US. METHODS: Participants with a well defined metabolic syndrome phenotype were recruited to CAPITAIN to reduce the influence of confounding factors. Validation and comparison datasets were selected comprising phenotypically similar subsets of individuals enrolled in PREVAIL-US and treated with pitavastatin or pravastatin, respectively. Mean change from baseline in parameters of glucose homeostasis (fasting plasma glucose [FPG], glycated hemoglobin [HbA1c], insulin, quantitative insulin-sensitivity check index [QUICKI] and homeostasis model of assessment-insulin resistance [HOMA-IR]) and plasma lipid profile were assessed at 6 months (CAPITAIN) and 3 months (PREVAIL-US) after initiating treatment. RESULTS: In CAPITAIN (n = 12), no significant differences from baseline in HbA1c, insulin, HOMA-IR and QUICKI were observed at day 180 in patients treated with pitavastatin. A small (4%) increase in FPG from baseline to day 180 (P < 0.05), was observed. In the validation dataset (n = 9), no significant differences from baseline in glycemic parameters were observed at day 84 (all comparisons P > 0.05). Similar results were observed for pravastatin in the comparison dataset (n = 14). CONCLUSIONS: Other than a small change in FPG in the CAPITAIN study, neutral effects of pitavastatin on glucose homeostasis were observed in two cohorts of patients with metabolic syndrome, independent of its efficacy in reducing levels of atherogenic lipoproteins. The small number of patients and relatively short follow-up period represent limitations of the study. Nevertheless, these data suggest that statin-induced diabetogenesis may not represent a class effect.

RESUMEN

OBJECTIVES: The aim of this retrospective cohort study was to determine the prevalence and severity of BPD and its predictors in a regional cohort of very preterm (VP) infants in Reunion Island. METHODS: All autochthonous VP infants, live-born before the 33rd week of gestation (WG) between 1st January 2008 and 31st December 2009, were eligible for the study. Only VP infants surviving at least 28 days, for whom the parameters were known from birth, were included in the case-control study of predictors of moderate to severe BPD (BPDmo/s). RESULTS: In VP infants less than 33 WG, the rate of overall BPD (3 grades of severity) was 30.7%. Among those who survived 28 days or more, the rate of BPDmo/s was 13.1% (95%CI: 10.2-15.9%). In VP infants less than 32 WG that survived at 36 WG, the prevalence of BPDmo/s was 18.2% (95% CI: 14.2-22.1%). In a fixed-effect logistic model, adjusted for gestational age, postnatal growth, and the mode of ventilation at 24h, 4 key factors were predictive of BDPmo/s: small for gestational age, surfactant, delayed energy intake, and late-onset neonatal infection. In a mixed-effect logistic model adjusted for these same cofactors, the site was associated with BPDmo/s, in line with a center-effect. CONCLUSION: The prevalence of BPDmo/s in the mixed-race population of Reunion Island is consistent with those observed in Europe but were site-specific. In our setting, predictors of individual BPDmo/s are similar to those already identified.

RESUMEN

OBJECTIVES: To compare the perinatal mortality and morbidity of infants born from monochorionic versus dichorionic twin pregnancies (TP). PATIENTS AND METHODS: Retrospective, comparative study of monochorionic and dichorionic TP over 10 years in the south of Reunion Island. Information regarding demographic, gestational and perinatal variables of mothers and infants was collected from the hospital perinatal database. RESULTS: Six hundred and twenty dichorionic and 155 monochorionic TP were analyzed. In case of monochorionic TP, mothers had higher rates of pregnancy-related hypertension (OR=1.82, 95%CI=[1.02-3.29] ; P=0.03) and hospitalization (OR=1.48, 95%CI=[1.02-2.16]; P=0.03). Newborns from monochorionic TP had higher morbidity for : very preterm birth (birth before 33 weeks gestation) (OR=1.65, 95%CI=[1.02-2.66]; P=0.02), very low birth weight (birth weight<1500g) (OR=1.73, 95%CI=[1.57-3.13]; P<0.001), Apgar<7 at 1 minute (OR=1.76, 95%CI=[1.18-2.61]; P<0.01) and hospitalization (OR=2.08, 95%CI=[1.58-2.73]; P<0.001). Perinatal mortality was also significantly higher (OR=2.47, 95%CI=[1.54-3.94]; P<0.001), as well intrauterine fetal death (OR=3.96, 95%CI=[1.95-8.05]; P<0.001) CONCLUSION: This study confirms that few differences exist among dichorionic and monochorionic TP with regard to maternal morbidity, while neonatal morbidity and mortality are higher in twins born from monochorionic pregnancies.

RESUMEN

BACKGROUND AND OBJECTIVES: In many jurisdictions, blood donors who have an atypical pulse rate are temporarily deferred. This practice is not supported by evidence. We evaluated whether accepting donors with an atypical pulse rate increases their risk of cardiac ischaemic events. METHODS: We measured the cumulative incidence of hospitalizations and deaths for coronary heart disease within 1 year of follow-up among donors who, between 2002 and 2006, were temporarily deferred because of an atypical pulse (<50 beats/min, >100 beats/min, or irregular). We compared this incidence to that observed among donors who also had an atypical pulse but who were allowed to donate, following a change in our deferral policy in 2007. The occurrence of cardiac events was determined through hospital discharge and death registries. RESULTS: Among 6076 donors who were temporarily deferred for an atypical pulse, the 1-year rate of hospitalization or death for cardiac ischaemic events was 3.5/1000, compared to 2.4 in donors who had an atypical pulse but who were allowed to donate (n =10,671), for an adjusted odds ratio of 1.7 (95% CI, 0.9-3.0, P=0.08). CONCLUSION: Regardless of the clinical significance of an atypical pulse rate, our data show that accepting donors with this condition does not increase the occurrence of serious cardiac ischaemic events. We conclude that pulse rate measurement in prospective donors is not warranted.

RESUMEN

OBJECTIVES: To investigate the determinants of Group B streptococcus (GBS) maternal colonization, as well as factors associated with its vertical transmission. PATIENTS AND METHODS: Case-control study on all singletons pregnancies delivered beyond at least 24 weeks of amenorrhoea in Southern Reunion maternities for which GBS screening was known. Multiple logistic regression analysis using 2004-2007 dataset of South Reunion birth registers. RESULTS: Out of 17,430 women delivered between 1st January 2004 and 31st December 2007, 2911 (16.7%) carried GBS. In a model adjusted on antenatal care, risk groups for GBS carriage were the women indigenous from another island of the Indian Ocean than Reunion (OR: 1.29, CI95%: 1.05-1.57) and obese women (body mass index ≥ 30, OR: 1.19, CI95%: 1.03-1.18). Protective factors included birthplace in mainland France (OR: 0.82, CI95%: 0.69-0.97) and underweight (OR: 0.81; CI95%: 0.69-0. 95). In a model controlling for a composite obstetrical variable delineating the protective roles of C-section and antibioprophylaxis as well as the putative role of meconium-stained fluids (thin, thick or fetid), all previously found in our setting, three key factors were independently associated with GBS vertical mother-to-child transmission: obesity (OR: 1.48, CI95%: 1.05-2.09), fetal tachycardia (OR: 4.92, CI95%: 2.79-8.68) and late preterm birth (35 to 36 wks, OR: 2.14, CI95%: 1.32-3.45). CONCLUSION: These findings strengthen the putative roles of corpulence and ethnicity in GBS acquisition previously found in the United States, while confirming an authentic role of obesity in its vertical transmission, independently of other classical cofactors lighted by our study.

RESUMEN

OBJECTIVE: In France, global rate of caesarian section in twin pregnancies has been 50.2% in 2003. Modes of delivery according to different twin presentations remain controversial in the literature. The purpose of our study is to analyze our practice of twin deliveries in a 5-year period, with neonatal outcomes. PATIENTS AND METHODS: Among 22,243 women having delivered in our maternity (22 weeks and over) during the study period, the study population consisted of 371 twin pregnancies, of which 305 after 33 weeks gestation. RESULTS: Different presentations were relatively identical whatever the gestational age of pregnancies: the "cephalic-cephalic" presentation represented 60 to 70% of the total, the "cephalic-breech" presentation approximately 10% while the "breech-cephalic" or "breech-breech" presentations approximately 8% each. Mean terms of pregnancies were 35.2 ± 2.8 weeks, mean birthweight being 2243 ± 561 g. C-section rate was 53.5%. When the first twin was in cephalic presentation, C-section rate was 40% while it was almost 100% when the first twin was in breech or "other" presentations. CONCLUSION: There were no significant differences in neonatal outcomes (mean birthweights, Apgar scores, transfers in neonatology, perinatal deaths) according to different mode of deliveries (vaginal or C-sections). Our policy of planned cesarean section may need to be revised.

RESUMEN

BACKGROUND AND OBJECTIVES: IgA deficiency is common (1/500) and up to 40% of affected individuals will develop anti-IgA. A few studies suggested that passive transfusion of anti-IgA was not associated with an increased risk of allergic reactions. This study was designed to assess the safety of transfusing blood components containing anti-IgA. MATERIALS AND METHODS: IgA-deficient blood donors with and without anti-IgA were identified from Héma-Québec's (HQ) computerized database. IgA deficiency was confirmed by an ELISA method and the presence of anti-IgA by a passive hemagglutination assay. Blood donations from IgA-deficient donors issued to hospitals between March 1999 and December 2004 were retrieved. Medical charts of recipients were reviewed for the occurrence of a suspected transfusion reaction. Presence and nature of transfusion reactions were assessed blindly by an adjudicating committee. RESULTS: A total of 323 IgA-deficient blood products were issued by HQ to 55 hospitals. Of these, 48 agreed to participate [315 blood products (97.5%)]. A total of 272 products were transfused: 174 contained anti-IgA, and 98 did not. Only two minor allergic reactions occurred in each group. Incidence of allergic reactions was 1.15% in the anti-IgA group and 2.04% in the group without anti-IgA (P = 0.91). There was no anaphylactic reaction in either group. CONCLUSIONS: This study indicates that the proportion of allergic reactions does not appear to be greater in recipients of blood components containing anti-IgA compared to recipients of non-anti-IgA-containing components. Allowing donations from IgA-deficient donors with anti-IgA may therefore be contemplated.

RESUMEN

Hypertensive disorders of pregnancy (HDP) represent globally 10% of human births and their major complication, preeclampsia, 3 to 5%. The etiology of these HDP remains still uncertain, however major advances have been made these last 25 years. The Sixth International Workshop on Reproductive Immunology, Immunological Tolerance and Immunology of Preeclampsia 2008 celebrated its 10th Anniversary in Reunion-island (French overseas Department in the Indian Ocean). Over this decade, these six workshops have contributed extensively to immunological, epidemiological, anthropological and even vascular debates. The defect of trophoblastic invasion encountered in preeclampsia, intra-uterine growth retardation and to some extend also preterm labour has been understood only at the end of the 1970's. On the other hand, clinical and epidemiological findings at the end of the 20th century permitted to apprehend that "preeclampsia disease of primiparae" may in fact well be the disease of first pregnancies at the level of human couples. Among the important advances, immunology of reproduction is certainly the topic where knowledge has literally exploded in the last decade. This paper relates some major steps in comprehension of this disease and focuses on the interest to follow these immunological works and their new concepts. It seems, at the beginning of the 21st century, that we are possibly closer than ever to understand the etiology of this obstetrical enigma. In this quest, the immunology of reproduction will certainly come out as one of the main players.

RESUMEN

Transfusion of a bacterially contaminated blood product can have serious consequences. We undertook an electronic survey of representative Canadian hospitals to determine current clinical and laboratory practices for investigating such reactions, prior to the development of national guidelines. There was considerable variability in symptoms and signs that would trigger investigation of possible contamination. The most frequent laboratory investigations performed were aerobic blood cultures of recipients and the residual component. If there is no residual product in the component bag, 36% of respondents would use a segment to perform testing. Guidelines could be helpful in improving and standardizing these practices.

RESUMEN

OBJECTIVES: The aim of this study was to describe the incidence of early onset neonatal infections (EONI) in the southern part of the Reunion Island, and to study the application of ANAES criteria. PATIENTS AND METHODS: A cross-sectional study was made of data collected for all live births having occurred between 1st January 2001 and 31st December 2004. RESULTS: Four hundred and thirty-seven in 16,071 neonates (out of 21,231 live births) presented with a certain or probable EONI, accounting for a regional rate of 20 per thousand (CI95 % 18-23 per thousand). Among 437 EONIs, group B streptococcus (GBS) was reported in 70.5% of the cases (n=308), Gram negative bacteria in 19.9% (n=87), of which nearly two thirds of Escherichia coli (n=56). Applying ANAES criteria led to identify 380 EONIs among 437 proven infections (sensitivity: 87%, specificity: 26%). A logistic regression analysis identified eight EONI predictors for the 7015 neonates for whom the mother GBS screening was documented: GBS positive vaginal culture (OR 4.2; CI95% 3.3-5.4), unexplained preterm birth less than 35 weeks (OR 5.7; CI95% 3.7-8.7), prolonged rupture of membranes greater than or equal to 18 hours (OR 2.1; CI95% 1.4-3.0), maternal fever greater than or equal to 37.8 degrees C (OR 3.2; CI95% 2.3-4.5), fetal tachycardia greater than or equal to 160 ppm (OR 2.7; CI95% 1.8-4.0), and thin (OR 1.6; CI95% 1.2-2.1) or thick meconium-stained amniotic fluid (OR 3.0; CI95% 2.1-4.5) or fetid fluid (OR 14.8; CI95% 4.2-51.8). CONCLUSION: The incidence of EONIS far exceeded that observed in metropolitan France, and the ANAES criteria lack sensitivity and specificity.

RESUMEN

OBJECTIVE: To compare the incidence of antenatal and intrapartum complications and neonatal outcomes among pre-pregnant obese women. METHODS: At the Sud-Reunion Hospital's maternity, Reunion Islands, France, over a 54-month period, each obese pregnant woman (BMI > or = 30 kg/m2) delivering a singleton after 22-weeks gestation was compared to the next age and parity-matched woman of normal pre-pregnancy weight (BMI 18.5-25 kg/m2), who delivered after the index case. The Students t test, Mann and Whitney test, Chi-square test and logistic regression model were used for statistical analysis. RESULTS: The study enrolled 2081 obese women and 2081 controls. The incidences of pre-eclampsia, chronic and pregnancy-induced hypertension, chronic and gestational diabetes mellitus were increased in the obese women group. Prenatal care in obese women required a high rate of hospitalizations as well as a high rate of insulin treatment. Obese women were more likely to be delivered by Caesarean section. The rate of in utero fetal death, neonatal and perinatal death was significantly higher in the obese women group. The high BMI in relation with both pre-eclampsia and in utero fetal death remained unchanged after adjustment of other risk factors. CONCLUSION: Obese women were more likely to present several obstetric complications and to be delivered by Caesarean section. Obstetricians who decide on a first Caesarean section in an obese woman should be aware of the cumulated obesity and uterine scar risks that could threaten any subsequent Caesarean section.


OBJETIVO: Comparar la incidencia de las complicaciones antenatales e intraparto, y los resultados neonatales entre las mujeres obesas pre-embarazadas. MÉTODOS: Por un periodo de más de 54 meses, cada mujer obesas embarazadas (IMC $ 30 kg/m2) dando a luz singletons después de 22 semanas de gestación, en el Hospital de Maternidad de Sud-Reunion, Reunion Island, Francia, fue comparados con la mujer de peso normal pre-embarazada siguiente, pareada por edad y paridad (IMC 18.5-25 kg/m2) dando a luz después del caso del índice. Para el an álisis estadístico se usó la prueba T de Student, la prueba de Mann-Whitney, la prueba de chi-cuadrado, y el modelo de regresión logística. RESULTADOS: El estudio enroló a 2081 mujeres obesas y 2081 controles. Las incidencias de pre-eclampsia, hipertensión inducida por el embarazo y crónica, así como la diabetes mellitus gestacional y crónica, aumentaron en el grupo de mujeres obesas. El cuidado prenatal en las mujeres obesas requirió una alta tasa de hospitalizaciones así como una alta tasa de tratamiento de insulina. Las mujeres obesas eran m ás propensas a tener el parto por ces área. La tasa de muerte fetal in útero, muerte neonatal y perinatal fue significativamente m ás alta en el grupo de mujeres obesas. El alto IMC en relación tanto con la pre-eclampsia como con la muerte fetal en útero permaneció igual después del ajuste de otros factores de riesgo. El alto IMC tanto en relación con la pre-eclampsia como con respecto la muerte fetal in útero permaneció igual después del ajuste de otros factores de riesgo. CONCLUSIÓN: Las mujeres obesas tuvieron mayor propensión a presentar varias complicaciones obstétricas y tener el parto mediante cesárea. Los obstetras que deciden practicar una primera cesárea en una mujer obesa deben tener conciencia de la obesidad acumulada y los riesgos de cicatriz uterina que podrían amenazar cualquier cesárea posterior.

RESUMEN

OBJECTIVE: To assess maternal and fetal outcomes in patients with gestational diabetes mellitus. PATIENTS AND METHODS: A retrospective study was conducted at the Sud-Reunion Hospital's maternity (French overseas department located in the Indian Ocean), during the period from January 1, 2001, through December 31, 2004. During this period, 1172 pregnant women presenting gestational diabetes mellitus were compared with 1172 non-diabetic controls matched on the basis of age, parity. Student t test, Pearson chi-square test and logistic regression model were used for statistical analysis. RESULTS: Gestational diabetes mellitus complicates about 7.5% of pregnancies in Reunion Island. Its occurrence was associated with a significantly increased prevalence of pre-pregnancy obesity (27 versus 9.4%) and chronic hypertension (5.3 versus 3.3%). The prevalence of preeclampsia and obstetrical vascular disorders were not different between the two groups, respectively 2.2 versus 2.7% (P=0.43) and 6.2 versus 4.4% (P=0.06). The rate of caesarean sections and inductions of labour was increased in the study group. The term of delivery was inferior in the study group, consecutive to increased rate of labour induction at 38 week-gestation. Macrosomia and large for gestational age (LGA) newborns rate were significantly higher in the study group, respectively 8.9 versus 4.2% and 22.5 versus 10.1% (P<0.001) but the rate of admission into neonatal unit was not significantly different. DISCUSSION AND CONCLUSION: Active management of gestational diabetes mellitus is associated with low maternal and perinatal morbidity. While age and parity are controlled by the study design, the prevalence of preeclampsia and gestational hypertension are not increased in women presenting gestational diabetes mellitus.
