Glycaemic,blood pressure and cholesterol control in 25 629 diabetics

Objective

To examine and compare the extent to which people with type 2 diabetes (T2DM) are achieving haemoglobin A_1c (HbA_1c), blood pressure (BP) and LDL cholesterol (LDL-C) treatment targets.

Methods

A review of databases (MEDLINE Ovid, Pubmed and Sabinet) was performed and limited to the following terms: type 2 diabetes mellitus AND guideline AND goal achievement for the years 2009 to 2014 (five years).

Results

A total of 14 studies (25 629 patients) were selected across 19 different countries. An HbA_1c level of 7.0% (or less) was achieved by 44.5% of subjects (range 19.2–70.5%), while 35.2% (range 7.4–66.3%) achieved BP of 130/80 mmHg (or less), and 51.4% (range 20.0–82.9%) had an LDL-C level of either 2.5 or 2.6 mmol/l (100 mg/dl or less).

Conclusion

Despite guideline recommendations that lowering of HbA_1c, BP and lipids to target levels in T2DM will lead to a reduction in morbidity and mortality rates, we found that control of these risk factors remains suboptimal, even across different settings.     

Tailored mental health care after nursing home admission: improving transfers of people with dementia with behavioral problems. An explorative study

Objectives: In the Netherlands, many community-dwelling people with dementia and behavioral disturbances and their family caregivers receive mental health care from a community psychiatric nurse (CPN). To promote continuity of care for these persons after moving to a nursing home, a transfer intervention was developed. The aim of this explorative study was to evaluate this intervention and its implementation.

Method: A qualitative explorative study design was used. CPNs visited professional nursing home carers, people with dementia and family caregivers six weeks after moving, advised on how to manage behavioral problems of their former clients and provided support to family caregivers. Twenty-two interviews were conducted with participants exposed to the intervention (5 CPNs, 5 family and 12 nursing home carers) and with 11 stakeholders (i.e., nursing home and mental health care managers, professional caregivers) to identify facilitators and barriers to the implementation. Data were collected in 2012 and 2013.

Results: The follow-up visit at six weeks met the need for background information of new admitted patients and helped family caregivers close off the period prior to the move. It did not meet the original purpose of providing nursing home staff with advice about problem behaviors on time: six weeks after the move was experienced as too late.

Conclusion: The transfer intervention increased the awareness of nursing home staff about personal and behavioral characteristics of residents with dementia and supported caregivers in coping with the new situation. The timing of the intervention could be improved by scheduling it immediately after the move.     

Stimulating spectrum of human recombinant multi-CSF (IL-3) on human marrow precursors: importance of accessory cells

Recently, human multi-CSF was obtained by molecular cloning. In the present study, the effects of multi-CSF in vitro were investigated by comparative culture of whole bone marrow or progenitor cells obtained by sorting the cell fraction that binds the monoclonal antibody (MoAb) B13C5 (CD 34). Multi-CSF stimulated erythroid (BFU-E), multipotential (CFU-GEMM) and eosinophil (CFU-Eo) colonies in cultures of the progenitor cell enriched fraction, whereas (besides BFU-E, CFU-GEMM, and CFU-Eo) granulocyte (CFU-G), granulocyte-macrophage (CFU-GM), and macrophage (CFU-M) colony-forming cells also were stimulated by multi- CSF when unfractionated bone marrow was cultured. Reconstitution of the progenitor cell fraction (B13C5 positive) with the B13C5-negative population restored the broad spectrum of progenitor cell stimulation. This suggested that accessory cells are required for expression of the full spectrum of progenitor cell stimulation by multi-CSF. Subsequently, specific marrow cell populations, including T lymphocytes, granulocytic cells, and monocytes, were prepared by using selected MoAbs in complement-mediated lysis or cell sorting, added to cultures of hematopoietic progenitors and tested for accessory cell function. The results demonstrate that small numbers of monocytes permit the stimulation of CFU-G, CFU-GM, and CFU-M by multi-CSF. These monocyte-dependent stimulating effects on CFU-G, CFU-GM, and CFU-M could also be achieved by adding recombinant GM-CSF as a substitute for monocytes to the cultures. Therefore, multi-CSF most likely has direct stimulative effects on BFU-E, CFU-GEMM, and CFU-Eo and indirect effects on CFU-G, CFU-GM, and CFU-M in the presence of monocytes.     

Nutritional status of Palestinian preschoolers in the Gaza Strip: a cross-sectional study

Background  

The authors examined factors associated with nutritional resilience/vulnerability among preschoolers in the Gaza Strip in 2007, where political violence and deprivation are widespread.     

Activation and increased expression of adhesion molecules on peripheral blood lymphocytes is a mechanism for the immediate lymphocytopenia after administration of OKT3

We investigated the mechanism by which antihuman CD3 monoclonal antibodies of the isotypes IgG2a (eg, OKT3) and IgA (eg, IXA) can induce the rapid disappearance of virtually all circulating T lymphocytes. We hypothesize that upregulation of adhesion molecules on the lymphocyte membrane contributes to this effect. However, this hypothesis is difficult to test, because of the inherent lymphocytopenia and/or shifts in lymphocyte populations between intra and extra-vascular compartments. Therefore, studies in vitro were performed, as well. Analysis of peripheral blood lymphocytes isolated at several times after addition of OKT3 or IXA to whole blood of healthy individuals showed an immediate increase in the proportion of T cells expressing NKI-L16, an activation epitope on CD11a/CD18. Likewise, an increase in CD11b/CD18 expression occurred. In parallel experiments, a transiently increased adhesion of T cells to endothelial cell monolayers was observed. This adhesion could be completely blocked by anti-CD18 or anti-CD11a monoclonal antibodies and only partly by an anti-CD11b antibody. Our data indicate that upregulation of activation epitopes of CD11a/CD18, as well as increased expression of CD11b/CD18 on T lymphocytes, may result in increased adhesion of these cells to intercellular adhesion molecule-1 (ICAM-1) and ICAM-2 on vascular endothelium. This phenomenon may, at least, partly explain the rapidly occurring peripheral lymphocytopenia observed in vivo.     

Preferential use of the VH4 Ig gene family by diffuse large-cell lymphoma

Ig heavy chain variable region (VH) genes expressed by human diffuse large-cell lymphoma (DLC) and follicular lymphoma (FL) were identified and analyzed with respect to germline gene families. In 67 cases of FL, VH region genes were expressed in a pattern similar to that of normal B cells, with a predominance of the large VH3 gene family being used. In contrast, of the 17 cases of DLC, there was an extremely biased use of VH genes. Of these DLC tumors, 88% expressed genes from the small VH4 gene family; and even among these tumors, there was a limited use of genes, with 11 cases producing Igs derived from the VH4.21 germline gene. Although most of the VH genes expressed by DLC tumor cells contained mutations with respect to their germline counterparts, almost all of these mutations occurred before the clonal expansion of the tumor. This contrasts with our previous findings of ongoing mutations in FL and represents a fundamental difference between these two malignancies. This preferential gene use implies an important role for the VH4 gene family, and specifically for VH4.21, in the genesis of DLC.
