Factors associated with recovery and recurrence of depression in older people: A prospective study

The Liverpool Continuing Health in the Community Study has followed up 1070 elderly community subjects over 6 years. In the first year 123 subjects had case-level depression. Three years later 49 (39.8%) of the previously depressed were recovered, 33 (26.8%) were depressed, 16 (13%) were not available for interview and 25 (20.3%) were dead. This study looks at factors associated with the 3-year outcome of patients who were depressed at year 0. Two outcome groups that were compared were a recovered depression group and a recurrent/persistent depression group. The factors that were significantly associated with a recurrence of depression (or persistent depression) at year 3 were bereavement of a close figure in the 6 months before interview, loneliness and life dissatisfaction at year 3. A variety of traditional risk factors for depression (including age, marital status, physical ill-health and incapacity) failed to attain significance in predicting recurrent or persistent depression. When combined, both recovered and recurrently depressed groups at year 3 had significantly higher levels of pain and a higher number of serious upsets in the past 6 months and 6 weeks compared to a compared to a control group. The depressed at year 0 were more likely to have entered more dependent forms of accommodation by year 3.     

Perception and social consequences of tuberculosis: A focus group study of tuberculosis patients in Sialkot, Pakistan

Treatment defaulting is one of the major causes of the failure of TB control programs. In Bethania Hospital. Sialkot, defaulting rates are high: 72% for the standard 12 months course and 56% for the 8 months course. Attrition is especially important in the first weeks of treatment: < 70% of the patients start the 10th week of treatment. A focus group discussion study has been carried out to gain a better understanding of the impact of social stigmatization, treatment cost and pregnancy on defaulting. The study population consisted of 3 male and 3 female groups each with 8 hospitalized TB patients. The study shows that TB is perceived as a very dangerous, infectious and incurable disease. This perception has many social consequences: stigmatization and social isolation of TB patients and their families; diminished marriage prospects for young TB patients, and even for their family members; TB in one of the partners may lead to divorce. Due to fear patients often deny the diagnosis and reject the treatment. While both male and female TB patients face many social and economical problems, female patients are more affected. Divorce and broken engagements seem to occur more often in female patients. Females are usually economically dependent on their husbands and family in law, and need their cooperation to avail of treatment. The belief that pregnancy enhances the risk for relapse decreases their marriage prospects. Pregnancy is also a reason for stopping TB treatment as both are considered as incompatible. The findings of this study reveal the urgent need for a health education campaign to convince the general population that tuberculosis is curable. All health care providers should act as destigmatizers.     

Is there a ‘Basque’ profile regarding autosomal recessive deficiencies of coagulation factors?*

When excluding haemophilia and von Willebrand disease, coagulation factors deficiencies constitute rare autosomal recessive disorders (<1 in 500,000) of less precisely defined epidemiology. We have reported herein the distribution of these entities in the French Basque Country, a genetic isolate of very old individualization with peculiar biological specificities. The prevalence of these disorders was markedly high, especially, as already shown, factor XI deficiency. This unusual profile needs to be discussed in the view of population genetics.     

Impaired early bone formation in periodontal fenestration defects in dogs following application of insulin-like growth factor (II). Basic fibroblast growth factor and transforming growth factor beta 1

Abstract. Effects of a topically applied growth factor combination on fibroblast migration, collagen fiber formation and bone regeneration were studied in standardized periodontal defects in 4 beagle dogs. Following elevation of facial mucoperiosteal flaps, fenestration defects, 3 mm in diameter, were made through the cortical bone and into the dentin of maxillary and mandibular teeth. Collagen sponges, impregnated with 200 ng insulin-like growth factor II, 20 ng basic fibroblast growth factor and 6 ng transforming growth factor beta 1 were fitted to defects randomly in right or left quadrants and the flaps repositioned and sutured. Contralateral control defects received the collagen with vehicle only. Experimental procedures were staggered to allow observations of healing 3, 7, 10, and 14 days after surgery. Histometric analysis showed no differences in fibroblast and collagen density between control and growth factor defects. Bone regeneration was significantly greater in control than in growth factor defects 10 and 14 days after surgery. The rate of healing generally appeared more affected by intra-dog variations or procedural variations than by the growth factor combination.

Levels of cardiovascular risk factors in type 2 diabetes mellitus are dependent on the stage of proteinuria.

Levels of cardiovascular risk factors were determined in 75 patients with Type 2 diabetes mellitus. The patients were divided into three groups according to their urinary protein excretion (UPE): (a) normal proteinuria (less than or equal to 70 mg d-1); (b) microproteinuria (70-500 mg d-1); and (c) macroproteinuria (greater than 500 mg d-1). A significant stepwise increase in mean systolic blood pressure, LDL-cholesterol and fibrinogen levels was observed from the first to the third investigated group of patients. Mean apoprotein B levels were significantly increased in the group with macroproteinuria compared to the other two groups. Significant linear correlations were found between UPE and LDL-cholesterol, total cholesterol, apoprotein B, creatinine, systolic blood pressure and diabetes duration. In summary, it is concluded that the levels of some cardiovascular risk factors increase with the stage of proteinuria in Type 2 diabetes mellitus.

Irritable bowel syndrome: The role of psychosocial factors

The irritable bowel syndrome (IBS) is a very common disorder of intestinal function characterized by variable symptoms of abdominal pain, diarrhea, constipation and bloating. The spectrum of severity ranges from mild symptoms, not worthy of clinical attention, to intense and continuous symptoms associated with impaired health-related quality of life and high health care use. Psychosocial disturbance is commonly found among patients with irritable bowel, but until recently, its precise role in the disorder was uncertain. The data now suggest that irritable bowel is not a psychiatric disorder per se, but psychosocial factors including life stress, psychiatric comorbidity and abnormal illness behavior, among others, influence how the illness is experienced and acted upon. Patients with mild symptoms usually respond to education, reassurance, dietary modification and, when needed, antimotility agents. However, patients with more severe symptoms, who usually have greater psychosocial disturbance, will also require behavioral interventions, and possibly psychopharmacological agents. In sum, a graduated, multicomponent plan of care that includes dietary, behavioral and pharmacological treatments is recommended.     

S-100 beta and insulin-like growth factor-II differentially regulate growth of developing serotonin and dopamine neurons in vitro.

To study the phenotypic specificity of S-100 beta and insulin-like growth factor II (IGF-II) for developing monoamine neurons, serotonin (5-HT) neurons from the embryonic day 14 (E14) rostral raphe or dopamine (TH) neurons from the substantia nigra/ventral tegmental area were cultured for 3 days in vitro (3 DIV) in the presence of these factors. Neuronotrophic effects were analyzed by computer-assisted morphometry of 5-HT and TH-immunoreactive neurons. S-100 beta and IGF-II differentially regulated the growth of 5-HT and TH neurons but did not affect their survival. S-100 beta significantly increased several parameters of neurite outgrowth by 5-HT neurons but inhibited the spatial extent (field area) of TH neurites. IGF-II promoted growth of cell bodies of both phenotype, but only stimulated neurite outgrowth by TH neurons. S-100 beta and IGF-II differentially affected the number of GFAP immunoreactive cells from raphe and substantia nigra, but these effects did not correlate with the specificity of neuronotrophic effects. S-100 beta and IGF-II immunoreactivities were expressed in glial cultures derived from the same brain regions, raising the possibility that these factors have autocrine effects on glia as well as paracrine actions on neurons. The results of this study suggest that specificity of neurotrophic factors for particular embryonic neurons may be correlated with their neurotransmitter phenotype.     

膀胱前间隙炎性假瘤临床病理观察及文献复习

目的 探讨膀胱前间隙炎性假瘤的临床病理特征及发病因素，以提高对本病的认识。方法 复习3例膀胱前间隙炎性假瘤的临床特征、组织病理学、免疫表型及相关文献。结果 3例患者均为女性，均为输卵管结扎术后1～2年发现膀胱前间隙炎性假瘤，CT及B超提示膀胱前壁肿块，但膀胱黏膜光滑。术中发现肿块位于膀胱前间隙并累及膀胱前壁。病理检查：眼观为灰白色质韧的结节状肿块，镜下见炎性假瘤的病理特征及不同程度炎症背景，有组织疏松区、黏液样区、部分区域梭形细胞和纤维母细胞排列杂乱，细胞较大，光镜检查时易误诊为肉瘤，但缺乏核异型。3例均成功行肿块连同部分膀胱壁切除术，随访3～5年无复发。结论 膀胱前间隙炎性假瘤形态上需与软组织肉瘤、结节性筋膜炎、术后梭形细胞结节、间质性膀胱炎等疾病相鉴别，既往输卵管结扎术和感染可能是其重要的致病因素。
