Grief intensity,coping and psychological health among family members and friends following a terrorist attack

Abstract

This study investigates the association of psychological health with grief intensity and coping style among family members and friends of terror victims. The data was collected from 164 bereaved individuals, on average, 18?months after the bombings occurred. The results demonstrated the significant role of problem-focused social support, and religious coping in dealing with grief intensity and contributing to the psychological health. The findings may be of considerable importance in therapeutic situations by providing direction for coping with both the effects of traumatic event and a traumatic loss, and for maintaining emotional stability through reworking relationships with the deceased.     

Renal involvement in the Laurence-Moon-Bardet-Biedl syndrome: report of five cases

.We report five patients with Laurence-Moon-Bardet-Biedl syndrome (LMBBS) who had renal involvement. Intravenous pyelography showed bilateral or unilateral calyceal clubbing and blunting in all patients. In addition, one patient had a parapelvic cyst in the left kidney and another had bilateral lobulated renal outlines of the fetal type. One patient had a urinary concentrating defect and two patients showed increased fractional sodium excretion. Estimated tubular phosphate reabsorption values were in normal limits in all of five patients. No patient had a urine acidification defect, proteinuria, glycosuria, or hyperaminoaciduria. One patient died from end-stage renal failure. The remaining four patients had normal serum creatinine values and estimated creatinine clearances. ^99mTechnetium-diethylenetriamine pentaacetate renal scanning showed prolonged and delayed concentration and delayed excretion in three of the four patients who survived. A focal scar was determined on the left kidney of one of four patients by ^99mtechnetium-dimercaptosuccinic acid renal scanning. All LMBBS cases with or without renal symptoms should be routinely evaluated for renal abnormalities. Renal scanning is a valuable method, especially for determining the renal involvement in the early stage of disease.

Normothermic renal artery perfusion: A comparison of perfusates

Hypothermia and preservative perfusates have been used to decrease ischemic renal injury. This study was performed to identify the preservative function of perfusates independent of the effects of hypothermia. Rats underwent 45 minutes of renal ischemia. Rectal and renal parenchyma temperatures were monitored and maintained within 1° C of normal. Perfusates were University of Wisconsin solution (UW), Euro-Collins solution, normal saline solution, and Ringer's lactate solution. A nonperfused ischemic control and a nonischemic control group were also evaluated. Parameters evaluated included serum creatinine and blood urea nitrogen levels, renal ischemic injury grade, renal weight, and gross appearance of the injured kidney. Rats treated with UW solution were found to have a significantly lower creatinine, blood urea nitrogen, and injury grade than the other three perfused groups. The external gross appearance of the UW-treated kidneys was normal, whereas that of the other groups demonstrated moderate to severe injury. Although the mean right/left renal weight difference of the UW-treated group was lower than that of the other three groups, this was not statistically significant. Under normothermic conditions in rats, UW solution affords significant renal protection from ischemia. Euro-Collins, normal saline, and Ringer's lactate solutions display no significant protective effect.Presented at the Twentieth Annual Meeting of the Peripheral Vascular Surgery Society, New Orleans, La., June 10, 1995.     

The effect of Bosentan on healing of colonic anastomosis

Background  

Ischemia is the most important factor compromises wound healing in colonic anastomosis. Mesenteric vessels are ligated at first while performing colonic resection and following anastomosis. Therefore blood supply of the related segments of colon temporarily interrupted and ischemia can easily occur. This study was carried out to explore whether Bosentan, an endothelin-receptor antagonist, can eliminate vasoconstruction, increase blood flow in the splanchnic area and anastomotic region and therefore possibly facilitate wound healing and prevent intra-abdominal adhesion formation.     

Control of primary osteosarcoma with chemotherapy

High-dose methotrexate with citrovorum factor "rescue" (MTX-CF) produced an apparent complete response of the primary tumor in three patients with osteosarcoma. The response was sustained with MTX-CF, intra-arterial cis-diamminedichloroplatinum II (CDP) and Adriamycin (doxorubicin) for 18 months. Treatment was then electively discontinued. Local recurrence occurred in two patients, 6 and 4 months later, respectively. MTX-CF was reinstated and a complete response was again achieved in one patient. This has been maintained for 15+ months with MTX-CF and intra-arterial CDP administered for 13 of the 15+ months. Reinduction with MTX-CF failed in the second relapsed patient but an apparent remission was again achieved with radiation and intra-arterial CDP. This has been maintained with intravenous CDP, cyclophosphamide and phenylalanine mustard for 14+ months. A complete response in the primary tumor was still present in the nonrelapsed patient, 42 months from diagnosis. All patients have remained free of pulmonary metastases, 40+ to 42+ months from diagnosis.     

Carbamazepine-induced sperm disorders can be associated with the altered expressions of testicular KCNJ11/miR-let-7a and spermatozoal CFTR/miR-27a

Male infertility is a global health problem, and the underlying molecular mechanisms are not clearly known. Ion channels and microRNAs (miRNAs), known to function in many vital functions in cells, have been shown to play a significant role in male infertility through changes in their expressions. The study aimed to evaluate the alterations of testicular and/or spermatozoal potassium voltage-gated channel subfamily J member 11 (KCNJ11), Cystic fibrosis transmembrane conductance regulator (CFTR), miR-let-7a and miR-27a expressions in carbamazepine-related male infertility. Here, we showed that carbamazepine reduced sperm motility, increased abnormal sperm morphology, and impaired hormonal balance as well as increased relative testis weight and decreased relative seminal vesicle weight. On the other hand, downregulated KCNJ11 and upregulated miR-let-7a expressions were determined in testis (p < .05). Also, downregulated KCNJ11 and upregulated CFTR and miR-27a expressions were found in spermatozoa (p < .05). Interestingly, altered testicular KCNJ11 and miR-let-7a expressions were correlated with decreased sperm motility and elevated sperm tail defect. Besides, spermatozoal CFTR and miR-27a expressions positively correlated with sperm tail defects. The results indicated a significant relationship between ion channel and/or miRNA expression alterations and impaired sperm parameters due to carbamazepine usage.     

Correlation of immune complexes in disseminated neuroblastoma with serum antibody to bovine serum albumin

To evaluate the relationship between tumor burden and circulating immune complexes (IC) in children with neuroblastoma (NBL), we studied sera collected at intervals from patients with disseminated (Stage III or IV) NBL. Sera from 10 of 12 patients contained IC by the Raji cell assay at some time during the first 9 to 11 months of the study. Higher IC levels were observed in sera of female patients. Fluid-phase C1q binding tests detected IC in only 16% of sera. IC measurements by either assay did not correlate with tumor burden. However, serum IC levels, as measured by the Raji cell assay, correlated significantly with serum antibody to bovine serum albumin (BSA) (rs = 0.54; p less than 0.001, rs = r as determined by Spearman rank correlation test). Measurement of anti-BSA antibodies in sera from the 12 patients, tested serially for circulating IC, and from five additional patients revealed that these had significantly higher anti-BSA activity than was found in sera from 13 age-matched controls. Sera from females also had relatively high levels of anti-BSA. Levels of antibody to bovine gamma-globulin and casein were not abnormal. Three sera with high IC levels (greater than 800 micrograms equivalents of heat-aggregated IgG) and relatively low anti-BSA activity appeared to contain "hidden" antibodies to BSA. These were demonstrated by measuring the increase in the ability of sera to bind 125I-BSA after they had been briefly acidified and then neutralized in the presence of the labeled BSA. The possible relevance of these results to the pathophysiology of NBL is discussed in light of earlier work that reported that serum IC levels correlate with the stage of the disease in NBL.
