Does Prison Crowding Predict Higher Rates of Substance Use Related Parole Violations? A Recurrent Events Multi-Level Survival Analysis

Objective

This administrative data-linkage cohort study examines the association between prison crowding and the rate of post-release parole violations in a random sample of prisoners released with parole conditions in California, for an observation period of two years (January 2003 through December 2004).

Background

Crowding overextends prison resources needed to adequately protect inmates and provide drug rehabilitation services. Violence and lack of access to treatment are known risk factors for drug use and substance use disorders. These and other psychosocial effects of crowding may lead to higher rates of recidivism in California parolees.

Methods

Rates of parole violation for parolees exposed to high and medium levels of prison crowding were compared to parolees with low prison crowding exposure. Hazard ratios (HRs) with 95% confidence intervals (CIs) were estimated using a Cox model for recurrent events. Our dataset included 13070 parolees in California, combining individual level parolee data with aggregate level crowding data for multilevel analysis.

Results

Comparing parolees exposed to high crowding with those exposed to low crowding, the effect sizes from greatest to least were absconding violations (HR 3.56 95% CI: 3.05–4.17), drug violations (HR 2.44 95% CI: 2.00–2.98), non-violent violations (HR 2.14 95% CI: 1.73–2.64), violent and serious violations (HR 1.88 95% CI: 1.45–2.43), and technical violations (HR 1.86 95% CI: 1.37–2.53).

Conclusions

Prison crowding predicted higher rates of parole violations after release from prison. The effect was magnitude-dependent and particularly strong for drug charges. Further research into whether adverse prison experiences, such as crowding, are associated with recidivism and drug use in particular may be warranted.     

Ethnic differences in survival after breast cancer in South East Asia

Background

The burden of breast cancer in Asia is escalating. We evaluated the impact of ethnicity on survival after breast cancer in the multi-ethnic region of South East Asia.

Methodology/Principal Findings

Using the Singapore-Malaysia hospital-based breast cancer registry, we analyzed the association between ethnicity and mortality following breast cancer in 5,264 patients diagnosed between 1990 and 2007 (Chinese: 71.6%, Malay: 18.4%, Indian: 10.0%). We compared survival rates between ethnic groups and calculated adjusted hazard ratios (HR) to estimate the independent effect of ethnicity on survival. Malays (n = 968) presented at a significantly younger age, with larger tumors, and at later stages than the Chinese and Indians. Malays were also more likely to have axillary lymph node metastasis at similar tumor sizes and to have hormone receptor negative and poorly differentiated tumors. Five year overall survival was highest in the Chinese women (75.8%; 95%CI: 74.4%–77.3%) followed by Indians (68.0%; 95%CI: 63.8%–72.2%), and Malays (58.5%; 95%CI: 55.2%–61.7%). Compared to the Chinese, Malay ethnicity was associated with significantly higher risk of all-cause mortality (HR: 1.34; 95%CI: 1.19–1.51), independent of age, stage, tumor characteristics and treatment. Indian ethnicity was not significantly associated with risk of mortality after breast cancer compared to the Chinese (HR: 1.14; 95%CI: 0.98–1.34).

Conclusion

In South East Asia, Malay ethnicity is independently associated with poorer survival after breast cancer. Research into underlying reasons, potentially including variations in tumor biology, psychosocial factors, treatment responsiveness and lifestyle after diagnosis, is warranted.     

Esophageal squamous cell carcinoma and adenocarcinoma in Malaysia – Pooled data from upper gastrointestinal centers in a multiethnic Asian population

BackgroundEsophageal cancer is the sixth leading cause of cancer death worldwide with considerable geographical histological variation There is a paucity of data in esophageal cancer in demographics, histology, and survival among the multi-ethnic Malaysian population. This paper is a review of esophageal cancer epidemiology and survival among esophageal cancer patients from data collected by the Malaysian Upper Gastrointestinal Surgical Society.MethodsThis is a multicenter retrospective observational study of esophageal cancer patients from six upper gastrointestinal surgical centers in Malaysia between 2005 and 2019. Patient characteristics, histological type and stage were compared and survival analyzed.ResultsThere were 820 patients with esophageal cancer included, where 442 (53.9 %) cases had squamous cell carcinoma (SCC) and 378 (46.1 %) had adenocarcinomas (AC). Malays were the predominant ethnicity with AC (66.7 %) while Indians were the ethnic majority (74.6 %) with SCC. Majority of patients (56.8 %) presented as stage IV disease. Overall, the 1-, 3-, and 5-years’ survival were 35.8 %, 13.8 % and 11.0 %, respectively. Surgical resection with curative intent yielded the best 5-year survival (29.4 %). Intervention in stage IV AC yielded superior survival when compared to SCC (median survival, 7.9 months vs 4.8 months; p, 0.018) Our series demonstrated an increase in AC to SCC over the last 15 years.ConclusionsThere was an ethnic preponderance seen between different histology in this region, not previously discussed. An increase in AC was observed over the last 15 years. Late diagnosis seen in most patients imparts poor prognosis as curative surgery affords the best outcome.     

Some Materials On The Assimilation Of Oklahoma Indians

Abstract

This article describes, in quite general terms, the current condition of the Indians of Oklahoma, with particular attention given the Cherokee. The author views the system of allotments in severalty and the policies of the Bureau of Indian Affairs as principal factors underlying the increased rate of assimilation of the Oklahoma tribes. She deals briefly with the Native American Church, and cites this as evidence of a reaction to assimilation on the part of the Indians.     

Joe Blackbear’S Story of the Origin Of the Peyote Religion*

Abstract

A folk explanation of certain aspects of peyote ritual and paraphanalia is offered in terms of an origin myth.

There is a story from long ago about the origin of peyote. It goes back to the time the Indians were fighting each other. On the other side of New Mexico, a group of Indians were camped and they were attacked by other bands. The mountains therewereveryhigh. The tribe that was attacked got scattered, There was just one woman and her boy left.     

Indian Boarding Schools And Ethnic Identity: An Example From The Southern Plains Tribes Of Oklahoma

Abstract

In the late 1800s, boarding schools sponsored by the United States government were created for the education and socialization of American Indian youth. These institutions gradually and purposefully pursued a policy of total assimilation of American Indians into the mainstream of society. The boarding schools failed in their ultimate goal to assimilate Indians. Surprisingly, however, they did attain limited acceptance among many Oklahoma Indians. The segregationist policies of the boarding schools are interpreted as having inadvertently perpetuated the formation of an Indian identity. Frequent visiting by family, segregation of Indian from non-Indian students, and symbolic association of the boarding schools with federal government obligations are identified as factors which contributed to the maintenance of this identity.     

Theories Of Culture Change Relevant to the Study Of the Dakota Indians

Abstract

In the literature various theories of culture change have been developed relevant to the Dakota Indians. These theories of change can be grouped under the headings of psychological, social, and cultural change.

Psychologically the changes in Dakota personality are seen as developing from the child-rearing process. Social change has been regarded as reflecting the changing values within the family circle due to pressure from white culture. Culture change has been hypothesized as due to indoctrination in the Dakota value system during childhood. It is this persistence of Dakota values which is the main deterrent to the acceptance of many non-Indian skills.     

Ethnic Variation in the Correlation Between Fasting Glucose Concentration and Glycated Hemoglobin (HbA1C)

ObjectiveWe aimed to determine the relationship between fasting serum glucose (FSG) concentration and glycated hemoglobin-Alc (HbAlc) in the 3 ethnicities in Singapore after adjustment for demographic and therapeutic variables.MethodsFasting serum glucose (FSG), HbAlc, and serum creatinine levels were simultaneously sampled from 575 patients with diabetes (389 Chinese, 97 Indians, 89 Malays) in this cross-sectional study between January and May 2008, and the results were subjected to multivariate linear regression analysis.ResultsWe found a significant interaction between FSG and ethnicity on HbAlc. The correlation between FSG and HbAlc among Chinese subjects was 0.25 (95% confidence interval [CI]:0.2-0.3) relative to the Malays (0.38, 95% CI: 0.30-0.45) after adjustment for age; gender; serum creatinine concentrations; body mass index (BMI); duration of diabetes; use of sulfonylureas, metformin, and insulin; and hemoglobin (Hb) and red cell indices (P = .005). Hence, for a given FSG, the predicted HbAlc will be higher in Malays compared to Chinese subjects.We did not observe a statistically significant difference between Indians and Malays with respect to the correlation between FSG and HbAlc.ConclusionWe showed a higher correlation between HbAlc and FSG in Malay subjects relative to the Chinese in this cohort. The ethnic variation in the HbAlc-FSG relationship may be related to differences in percentage contribution by the FSG to overall HbAlc among ethnic groups. Future studies using continuous glucose monitoring (CGM) to elucidate the relative contributions by FSG and postprandial glucose (PPG) to the daily blood glucose profile and the overall HbA1c by ethnicity are required.

Structure And Complexity Of Medicine Bundle Systems Of Selected Plains Indian Tribes

Abstract

A general overview of the medicine bundle complex of historic Plains Indians is presented in order to elucidate its systemic components. A working definition of the medicine bundle complex is offered, based on the following criteria: acquisition, purpose. material makeup of the bundle, ritual use, and disposition. The underlying conceptual principle of power transfer is discussed in conjunction with these systemic components.By drawing on selected tribal examples, the structure and complexity of specific tribal manifestations of the medicine bundle complex or system are examined in light of ecological adaptations and organizational complexity. It is suggested that the complexity of tribally-oriented bundle systems within the sample are a function of the level of organizational complexity of the selected tribes. Organizational complexity, in turn, is seen as developing out of certain ecological conditions, augmented by the pre-horse cultural backgrounds of the representative tribes.     

Disparities in survival improvement for U.S. childhood and adolescent cancer between 1995 and 2019: An analysis of population-based data

BackgroundAlthough treatment advances have increased childhood and adolescent cancer survival, whether patient subgroups have benefited equally from these improvements is unclear.MethodsData on 42,865 malignant primary cancers diagnosed between 1995 and 2019 in individuals ≤ 19 years were obtained from 12 Surveillance, Epidemiology, and End Results registries. Hazard ratios (HRs) and 95 % confidence intervals (CIs) for cancer-specific mortality by age group (0–14 and 15–19 years), sex, and race/ethnicity were estimated using flexible parametric models with a restricted cubic spline function in each of the periods: 2000–2004, 2005–2009, 2010–2014 and 2015–2019, versus 1995–1999. Interactions between diagnosis period and age group (children 0–14 and adolescents 15–19 years at diagnosis), sex, and race/ethnicity were assessed using likelihood ratio tests. Five-year cancer-specific survival rates for each diagnosis period were further predicted.ResultsCompared with the 1995–1999 cohort, the risk of dying from all cancers combined decreased in subgroups defined by age, sex and race/ethnicity with HRs ranging from 0.50 to 0.68 for the 2015–2019 comparison. HRs were more variable by cancer subtype. There were no statistically significant interactions by age group (P_interaction=0.05) or sex (P_interaction=0.71). Despite non-significant differences in cancer-specific survival improvement across different races and ethnicities (P_interaction=0.33) over the study period, minorities consistently experienced inferior survival compared with non-Hispanic Whites.ConclusionsThe substantial improvements in cancer-specific survival for childhood and adolescent cancer did not differ significantly by different age, sex, and race/ethnicity groups. However, persistent gaps in survival between minorities and non-Hispanic Whites are noteworthy.     

Latino/a professionals as entrepreneurs: how race,class, and gender shape entrepreneurial incorporation

ABSTRACT

This paper examines how race, class, and gender intersect to shape professional Latinos’ entrepreneurial incorporation, as observed by the conditions that prompt professional Latinos to start a business, including access to capital and experiences with discrimination. In-depth interviews with professional Latino business owners in Los Angeles reveal that individual human capital – via resources and wealth accrued through corporate careers – facilitates entrepreneurial activity. Race, ethnicity, and gender, as intersectional social group identities, combine with class to shape variegated impacts on access to capital and business experiences by gender and target market. Ethnicity is a resource for those serving the coethnic community and is more significant in shaping business ownership experiences for men who target a racially/ethnically diverse clientele, whereas gender and race are more salient for women outside the coethnic community. This study contributes to the ethnic enterprise literature by going beyond ethnicity to demonstrate that multiple dimensions of identity shape professional Latino/as’ entrepreneurial incorporation.     

Survival disparities for childhood cancers exist when defined by race/ethnicity and sex

BackgroundThere are documented racial/ethnic and sex differences in pediatric cancer survival; however, it is unknown whether pediatric cancer survival disparities exist when race/ethnicity and sex are considered jointly.MethodsUsing SEER data (2000–2017), we estimated survival differences by race/ethnicity within sexes and by sex within race/ethnicity (White, Black, Hispanic, and Asian/Pacific Islander [API]) for 17 cancers in children aged (0–19 years). Kaplan-Meier curves (Log-Rank p-values) were assessed. Cox regression was used to estimate hazards ratios (HRs) and 95 % confidence intervals (95 % CIs) between race/ethnicity/sex and cancer.ResultsWe included 51,759 cases (53.6 % male, 51.9 % White). There were statistically significant differences in 18-year survival by race/ethnicity-sex for 12/17 cancers. Within sexes, minorities had an increased risk of death compared to Whites for various cancers including acute lymphoblastic leukemia (ALL) (females: HispanicHR: 1.78, 95 % CI: 1.52, 2.10; BlackHR: 1.70, 95 % CI: 1.29, 2.24; APIHR: 1.42, 95 % CI: 1.07–1.89; males ALL: HispanicHR: 1.58, 95 % CI: 1.39,1.79; BlackHR: 1.57, 95 % CI: 1.26,1,95; API-HR: 1.39, 95 % CI: 1.11, 1.75) and astrocytoma (females: HispanicHR: 1.49, 95 % CI: 1.19, 1.85; BlackHR: 1.67, 95 % CI: 1.29, 2.17; API-HR: 1.51, 95 % CI: 1.05, 2.15; males: HispanicHR:1.27, 95 % CI: 1.04, 1.56; BlackHR: 1.69, 95 % CI: 1.32, 2.17; API-HR: 1.92, 95 % CI: 1.43, 2.58). Sex differences in survival within racial/ethnic groups were observed for White (ALL, osteosarcoma), Hispanic (medulloblastoma), and API (Primitive Neuro-Ectodermal Tumor [PNET]) children.ConclusionsThere are disparities in survival by both race/ethnicity and sex highlighting the societal and biologic influences these features have on survival in children with cancer.     

The Prevalence of Gestational Diabetes Mellitus Among Asian Females is Lower Using the New 2013 World Health Organization Diagnostic Criteria

ObjectiveTo determine the impact of the new 2013 World Health Organization (WHO) criteria for gestational diabetes mellitus (GDM) diagnosis on GDM prevalence and pregnancy outcomes in Asian ethnic groups compared to the 1999 WHO criteria.MethodsA retrospective cohort study included 855 pregnant females of Chinese, Malay, and Asian Indian ethnicity at high risk of GDM who underwent 75-g oral glucose tolerance tests (OGTTs) between July 2008 and June 2010 in a tertiary center in Singapore. GDM prevalence, reclassification, and pregnancy outcomes were determined using the 2013 and 1999 diagnostic cutoffs for fasting and 2-hour postglucose (PG) values.ResultsThe prevalence of GDM was reduced from 28.8% to 21.1% when the 2013 criteria were used. Overall, 10.2% subjects were reclassified from GDM to normal using the 2013 criteria, and 2.6% were reclassified from normal to GDM, giving a net reclassification rate of 12.8%. Reclassification from GDM to normal was greatest among Chinese, followed by Asian Indians, but the prevalence rate was unchanged among Malays. Babies of mothers who were reclassified from normal to GDM were more likely to have birth weight > 95^th centile and shoulder dystocia.ConclusionThe prevalence of GDM was reduced when the 2013 criteria were used, with the greatest reduction seen among Chinese, followed by Asian Indians. Lowering the fasting cutoff as per the new criteria identified a select group of patients who might benefit from GDM treatment. However, raising the 2-hour PG cutoff would miss a significant number of patients who might potentially benefit from GDM treatment. (Endocr Pract. 2014;20:1064-1069)     

The impact of transportation time on apoptosis in allogeneic stem cell grafts and the clinical outcome in malignant patients with unrelated donors

BackgroundThe quality of cells in peripheral blood stem cell (PBSC) grafts is important for allogeneic stem cell transplantation outcome. The viability of PBSC grafts may decrease during transportation time between donor and transplant center. We hypothesize that the graft viability based on apoptosis and necrosis in the graft may better reflect graft quality and clinical outcome.MethodsPBSC graft viability from unrelated donors was analyzed in 91 patients. Viable cells were defined as 7-aminoactinomycin D– and Annexin V–negative. The clinical outcome, including survival, transplant-related mortality and graft-versus-host disease (GvHD), was correlated to graft viability.ResultsGrafts transported for 1 day had a median viability of 86.4% (range 63.8 to 98.9%), and grafts transported for 2 days had median viability of 83.2% (range 52.8% to 96.2%) (P = .003). Grafts were divided into two groups based on the median graft viability of 85.1%. Patients who received low viability grafts had lower 1-year survival of 63.7% compared with 88.9% for those who received high viability grafts (P = .007). In the multivariate analysis, transplant-related mortality (TRM) was higher in the low viability group (P = .03), whereas overall survival was not significantly associated with graft viability. The incidence of acute GvHD grade II to IV, chronic GvHD and relapse risk remained comparable between the groups.ConclusionLow graft viability was an independent predictor of 1-year survival and TRM after adjusting for multiple confounders. Better graft quality markers are important for the detection of clinically important variations in the stem cell graft.     

Childhood Cancer Incidence in British Indians & Whites in Leicester, 1996–2008

Background

South Asians in England have an increased risk of childhood cancer but incidence by their individual ethnicities using self-assigned ethnicity is unknown. Our objective was to compare the incidence of childhood cancer in British Indians and Whites in Leicester, which has virtually complete, self-assigned, ethnicity data and the largest population of Indians in England.

Methods

We obtained data on all cancer registrations from 1996 to 2008 for Leicester with ethnicity obtained by linkage to the Hospital Episodes Statistics database. Age-standardised incidence rates were calculated for childhood cancers in Indians and Whites as well as rate ratios, adjusted for age.

Results

There were 33 cancers registered among Indian children and 39 among White children. The incidence rate for Indians was greater compared to Whites for all cancers combined (RR 1.82 (95% CI 1.14 to 2.89); p = 0.01), with some evidence of increased risk of leukaemia (RR 2.20 (0.95 to 5.07); p = 0.07), lymphoma (RR 3.96 (0.99 to 15.84); p = 0.04) and central nervous system tumours (RR 2.70 (1.00 to 7.26); p = 0.05). Rates were also higher in British Indian children compared to children in India.

Conclusions

British Indian children in Leicester had an increased risk of developing cancer compared to White children, largely due to a higher incidence of central nervous system and haematological malignancies.     

Stressful life experiences and risk of relapse of breast cancer: observational cohort study

ObjectiveTo confirm, using an observational cohort design, the relation between severely stressful life experiences and relapse of breast cancer found in a previous case-control study.DesignProspective follow up for five years of a cohort of women newly diagnosed as having breast cancer, collecting data on stressful life experiences, depression, and biological prognostic factors.SettingNHS breast clinic, London; 1991-9.ParticipantsA consecutive series of women aged under 60 newly diagnosed as having a primary operable breast tumour. 202/222 (91%) eligible women participated in the first life experiences interview. 170 (77%) provided complete interview data either up to 5 years after diagnosis or to recurrence.ResultsWe controlled for biological prognostic factors (lymph node infiltration and tumour histology), and found no increased risk of recurrence in women who had had one or more severely stressful life experiences in the year before diagnosis compared with women who did not (hazard ratio 1.01, 95% confidence interval 0.58 to 1.74, P=0.99). Women who had had one or more severely stressful life experiences in the 5 years after diagnosis had a lower risk of recurrence (0.52, 0.29 to 0.95, P=0.03) than those who did not.ConclusionThese data do not confirm an earlier finding from a case-control study that severely stressful life experiences increase the risk of recurrence of breast cancer. Differences in case control and prospective methods may explain the contradictory results. We took the prospective study as the more robust, and the results suggest that women with breast cancer need not fear that stressful experiences will precipitate the return of their disease.

What is already known on this topic

Women with apparently similar tumours at the time of presentation with breast cancer differ considerably in their disease-free survival and overall survivalSuch differences in outcome may well be explained by host and environmental factors, which could include psychological and social variablesData on the relation between severely stressful life experiences and cancer progression have been contradictory

What this study adds

Women who have a severely stressful life experience in the year before being diagnosed with breast cancer, or in the five years afterwards, do not seem to be at increased risk of developing a recurrence of the diseaseWomen with breast cancer need not fear that stressful experiences will precipitate the return of their disease.     

Ethnic groups and high sensitivity C-reactive protein in Israel

Abstract

High-sensitivity C-reactive protein (hs-CRP) is a biomarker that correlates with atherothrombotic risk and outcome. hs-CRP is influenced by various modifiable and non-modifiable factors. We studied the relationship between ethnic background and hs-CRP level, among the Jewish population in Israel. A total of 3659 men and 2180 women were divided into two ethnic groups (Ashkenazi and Sephardic Jews), based on the knowledge of Jewish immigration patterns throughout the centuries. Mean hs-CRP levels were calculated for each group and were adjusted for various factors known to influence hs-CRP. Sephardic Jews were found to have higher adjusted mean hs-CRP levels (2.0 mg l^?1 for men and 3.9 mg l^?1 for women) compared with Ashkenazi Jews (1.5 mg l^?1 for men and 2.9 mg l^?1 for women). Ethnic background emerged as an independent significant predictor of hs-CRP levels. We demonstrated that ethnicity is an important factor when considering hs-CRP as a marker of atherothrombotic risk.     

Heterogeneity of coronary heart disease risk factors in Indian,Pakistani, Bangladeshi,and European origin populations: cross sectional study

ObjectiveTo compare coronary risk factors and disease prevalence among Indians, Pakistanis, and Bangladeshis, and in all South Asians (these three groups together) with Europeans.DesignCross sectional survey.SettingNewcastle upon Tyne.Participants259 Indian, 305 Pakistani, 120 Bangladeshi, and 825 European men and women aged 25-74 years.ResultsThere were differences in social and economic circumstances, lifestyles, anthropometric measures and disease both between Indians, Pakistanis, and Bangladeshis and between all South Asians and Europeans. Bangladeshis and Pakistanis were the poorest groups. For most risk factors, the Bangladeshis (particularly men) fared the worst: smoking was most common (57%) in that group, and Bangladeshis had the highest concentrations of triglycerides (2.04 mmol/l) and fasting blood glucose (6.6 mmol/l) and the lowest concentration of high density lipoprotein cholesterol (0.97 mmol/l). Blood pressure, however, was lowest in Bangladeshis. Bangladeshis were the shortest (men 164 cm tall v 170 cm for Indians and 174 cm for Europeans). A higher proportion of Pakistani and Bangladeshi men had diabetes (22.4% and 26.6% respectively) than Indians (15.2%). Comparisons of all South Asians with Europeans hid some important differences, but South Asians were still disadvantaged in a wide range of risk factors. Findings in women were similar.ConclusionRisk of coronary heart disease is not uniform among South Asians, and there are important differences between Indians, Pakistanis, and Bangladeshis for many coronary risk factors. The belief that, except for insulin resistance, South Asians have lower levels of coronary risk factors than Europeans is incorrect, and may have arisen from combining ethnic subgroups and examining a narrow range of factors.

Key messages

• South Asians have more coronary heart disease than Europeans despite apparently lower levels of risk factors
• This study shows that Indians, Pakistanis and Bangladeshis differ in a wide range of coronary risk factors and combining their data is misleading
• Among South Asians, Indians were least and Bangladeshis most disadvantaged in a range of coronary risk factors. South Asians were disadvantaged in comparison with Europeans
• Future research and prevention strategies for coronary heart disease in South Asians should acknowledge a broad range of risk factors, the heterogeneity of these populations, linguistic and cultural needs, and environmental factors

     

Ethnic Differences in Glycaemic Control in People with Type 2 Diabetes Mellitus Living in Scotland

Background and Aims

Previous studies have investigated the association between ethnicity and processes of care and intermediate outcomes of diabetes, but there are limited population-based studies available. The aim of this study was to use population-based data to investigate the relationships between ethnicity and glycaemic control in men and women with diabetes mellitus living in Scotland

Methods

We used a 2008 extract from the population-based national electronic diabetes database of Scotland. The association between ethnicity with mean glycaemic control in type 2 diabetes mellitus was examined in a retrospective cohort study, including adjustment for a number of variables including age, sex, socioeconomic status, body mass index (BMI), prescribed treatment and duration of diabetes.

Results

Complete data for analyses were available for 56,333 White Scottish adults, 2,535 Pakistanis, 857 Indians, 427 Chinese and 223 African-Caribbeans. All other ethnic groups had significantly (p<0.05) greater proportions of people with suboptimal glycaemic control (HbA1c >58 mmol/mol, 7.5%) compared to the White Scottish group, despite generally younger mean age and lower BMI. Fully adjusted odds ratios for suboptimal glycaemic control were significantly higher among Pakistanis and Indians (1.85, 95% CI: 1.68–2.04, and 1.62,95% CI: 1.38–1.89) respectively.

Conclusions

Pakistanis and Indians with type 2 diabetes mellitus were more likely to have suboptimal glycaemic control than the white Scottish population. Further research on health services and self-management are needed to understand the association between ethnicity and glycaemic control to address ethnic disparities in glycaemic control.     

“Metabolic” Surgery For Treatment Of Type 2 Diabetes Mellitus

ObjectiveTo discuss the potential contribution of “metabolic” surgery in providing optimal management of patients with type 2 diabetes mellitus (T2DM).MethodsA literature search was performed with use of PubMed, and the clinical experience of the authors was also considered.ResultsBariatric—or, more appropriately, metabolic—surgical procedures have been shown to provide dramatic improvement in blood glucose levels, blood pressure, and lipid control in obese patients with T2DM. In these patients, metabolic surgery involves a low risk of short-term mortality and a significant long-term survival advantage, whereas the diagnosis of diabetes is associated with significant long-term mortality. Experimental studies in animals and clinical trials suggest that gastrointestinal bypass procedures can control diabetes and associated metabolic alterations by mechanisms independent of weight loss. As a result, the use of bariatric surgery and experimental gastrointestinal manipulations to treat T2DM is increasing, even among less obese patients. Although body mass index (BMI) currently is the most important factor for identifying candidates for bariatric surgery, evidence shows that a specific cutoff BMI value cannot accurately predict successful surgical outcomes. Furthermore, BMI appears limited in defining the risk profile for patients with T2DM.ConclusionCurrent BMI-based criteria for performance of bariatric surgery are not adequate for determining eligibility for operative treatment in patients with diabetes. Large clinical trials, comparing bariatric surgery versus optimal medical care of patients with T2DM, should be given priority in order to define the role of surgery in the management of diabetes. Recognizing the need to work as a multidisciplinary team that includes endocrinologists and surgeons is an initial step in addressing the issues and opportunities that surgery offers to diabetes care and research.
