Influence of psychical trauma through transgenerational transfer on the development of traumatic reactions in women with diagnosed breast cancer

Earlier experience of psychological trauma of a close person can through a transgenerational transfer influence traumatic reactions of a person going through a trauma at present, resulting in a repetition of earlier traumatic experiences and a development of a variety of mental disturbances. Purpose of our study was to evaluate the influence of transgenerational transfer on the development of Posttraumatic stress disorder (PTSD) in women with diagnosed breast cancer that had a family member with diagnosed cancer. The sample mainly consisted of 120 women treated in a Department of Oncology, Osijek University Hospital Center with diagnosis of newly discovered breast cancer, during the conduction of radio therapy having values Hamilton depression scale (HAM-D) from > or = 8 to < or = 24 or values Hamilton anxiety scale (HAM-A) from > or = 17 to < or = 30. Psychotherapeutic interview with a detailed clinical overview and with applying diagnostic criteria according to DSM-IV for mental disorders, specially structured non-standardized questionnaire for etiologic factors evaluation of the beginning of examinees' mental disorder, Los Angeles Symptom Checklist of PTSD symptoms (LASC), Hamilton's scale for anxiety evaluation (HAM-A) and Hamilton's scale for depression evaluation (HAM-D) were used. Results show that 61 (51%) of patients have a family member with diagnosed cancer. The average total value on LASC for examinees that had a family member with diagnosed cancer was slightly higher (22.92) in comparison to those who had no such family member (20.88). No statistically significant connection was found between having a family member with diagnosed cancer and the average total value on LASC. Although no connection was established between having a family member with diagnosed cancer and the average value on LASC in women with diagnosed breast cancer, transgenerational transfer of emotions seems to be important in their traumatic reactions, but it is still insufficiently researched and it is a challenge for future researches leaving many complicated issues open.     

Influence of in-hospital cardiac rehabilitation on psychological status after myocardial infarction in patients with D-type personality

The aim of this study was to determine the number of D-type personality patients in the group with a history of myocardial infarction (MI) and the influence of comprehensive in-hospital cardiac rehabilitation (iCR) on their psychological status (PS). The study included 316 consecutive patients aged 18 to 65 with MI in the last six months admitted into the programme of iCR. Surgical revascularized patients, clinically unstable patients and patients with sever chronic diseases and disorders were excluded. At the beginning and in the end of iCR diagnostic exam, hematological/biochemical blood analysis, ergometric testing was conducted. At the beginning and four weeks after the finish of the iCR estimation of PS was conducted. Distress scale 14 (DS14) questioner was used for that purpose. In the period of three weeks, patients were included in the programme of comprehensive iCR. Out of 316 patients in the study group 83.2% were male, while 16.8% were female. Average age of the patient was 51.3 +/- 7.2. When being admitted to iCR 42.7% patients had characteristics of D-type personality. Those patients had substantially lower level of body mass and body mass index. In the same time there were no differences among groups in risk factors, values of clinical, laboratory and diagnostic parameters. During iCR study group had more complications in comparison to the control group. At the end of iCR substantial rise of functional capacity of patients, improvement of lipid profile and lowering of glycaemia was recorded. Also at the end of iCR antiarrhythmics and psychopharmaceutical medicaments were more often prescribed to the patients in the study group. Four weeks after the iCR share of D-type personality patients was 41% and 71% of study group patients kept their D-type structure.     

Studies on Zn(II) and Cd(II) heteroligand complexes with RC(S)NHP(O)(OiPr)2 (R = Ph, NH2, PhNH) and α-diimine (bpy and phen) ligands. C-Cl bond cleavage of CH2Cl2 by [Zn(phen){PhC(S)NP(O)(OiPr)2}2]

The reaction of [ZnL^I,II₂] (L^I = [NH₂C(S)NP(O)(OiPr)₂]⁻; L^II = [PhNHC(S)NP(O)(OiPr)₂]⁻) or [Cd₂L^IV₄] (L^IV = [PhC(S)NP(O)(OiPr)₂]⁻) with 2,2′-bipyridine (bpy) or 1,10-phenanthroline (phen) leads to the heteroligand complexes [Zn(bpy)L^I,II₂], [Zn(phen)L^I,II₂], [Cd(bpy)L^IV₂] or [Cd(phen)L^IV₂], respectively. The introduction of the diimine ligands into the coordination sphere of the metal cation provokes a change from 1,5-O,S- to 1,3-N,S-coordination of the anionic ligands for Zn but not for the Cd species. The reaction of [Zn(phen)L^IV₂] (L^IV = PhC(S)NP(O)(OiPr)₂⁻) with CH₂Cl₂ cleaves the chlorine atoms from CH₂Cl₂ and leads to the formation of [Zn(phen)L^IVCl] and S,S′-bis(benzimidothio-N-diisopropoxyphosphoryl)methane (L^IV-CH₂-L^IV) in high yields. Using CHCl₃ or CCl₄ instead of CH₂Cl₂ does not lead to the formation of chlorine substituted products even under reflux conditions. The new compounds were investigated by ¹H and ³¹P{¹H} NMR, IR spectroscopy and microanalysis. Crystal structures of [ZnL^II₂], [Cd(phen)L^IV₂]·CH₂Cl₂, [Zn(bpy)L^I₂] and [Zn(phen)L^IVCl] were elucidated by X-ray diffraction.     

The antibacterial threaded-lasso peptide capistruin inhibits bacterial RNA polymerase

Capistruin, a ribosomally synthesized, post-translationally modified peptide produced by Burkholderia thailandensis E264, efficiently inhibits growth of Burkholderia and closely related Pseudomonas strains. The functional target of capistruin is not known. Capistruin is a threaded-lasso peptide (lariat peptide) consisting of an N-terminal ring of nine amino acids and a C-terminal tail of 10 amino acids threaded through the ring. The structure of capistruin is similar to that of microcin J25 (MccJ25), a threaded-lasso antibacterial peptide that is produced by some strains of Escherichia coli and targets DNA-dependent RNA polymerase (RNAP). Here, we show that capistruin, like MccJ25, inhibits wild type E. coli RNAP but not mutant, MccJ25-resistant, E. coli RNAP. We show further that an E. coli strain resistant to MccJ25, as a result of a mutation in an RNAP subunit gene, exhibits resistance to capistruin. The results indicate that the structural similarity of capistruin and MccJ25 reflects functional similarity and suggest that the functional target of capistruin, and possibly other threaded-lasso peptides, is bacterial RNAP.     

Non linear anthropometric predictors in swimming

In this paper we have tried to identify the significance and character of the linear and non-linear relations between simple anthropometric predictors: body height (BH), body weight (BW), and body mass index, and swimming performance: freestyle swimming 50 (FS50) and 400 meters (FS400), in a sample of young (15 years old on average) male (N = 40) and female (N = 28) swimmers. Linear (general model: y = a+bx) and nonlinear regression (general model: y = a+bx+cx2) were calculated simultaneously. Morphological variables are a significantly better predictor of the FS50 in males (BH mostly), and FS400 in females (BW mostly). This study emphasized some of the main advantages in the nonlinear regression calculation (including an interpretation of the relationships at a more superior level), and consequently allowed a precise anthropometric modeling in swimming using simple and easily measurable variables. For example, the best results in FS400 can be expected for the subjects that are average in BW (which guarantees solid muscle mass--the generator of force), but above average in BH (because of the physical law of lever). In conclusion, nonlinear regressions allow one to define the real nature of the relationships between variables, but only if compared with the linear ones. Additionally, this study emphasized one of the most important factors in defining possible specification-equation (e.g. structure of the influence of the different dimensions on the sport achievement) in different sports. In short, it underlines the importance of sampling the appropriate sample of the subject--highly skilled athletes exclusively.     

Ovarian cancer: PCD and brain metastases

Paraneoplastic cerebellar degeneration (PCD), the one of the most common paraneoplastic syndromes, refer to clinical disorders associated mostly with lung, ovarian and breast cancer, but not directly caused by the cancer or its metastases. Pathologic finding is an extensive loss of Purkinje cells in the cerebellum. Immunohistochemically, the auto-antibodies on the Purkinje cells had been detected. Clinically, PCD is characterized by sub-acutely evolving pancerebellar symptoms. Neurological dysfunction may appear before the detection of the underlying cancer. Therefore, the surgical exploration is necessary for the final diagnosis. The patient undergoes specific therapy. Soon, neurological status of the patient gets irreparable worse. Death come usually 2-3 years after the first symptoms of the PCD occurs. Case of a 63-years old woman with PCD as the first evidence of her cancer is reported. The patient developed brain metastases and died almost 3 years after the first symptoms of PCD occur     

The prevalence of cardiovascular disease risk factors in patients from Croatian Zagorje County treated at Department of Medicine, Zabok General Hospital from 2000 to 2006

The aim of the study was to assess the prevalence of risk factors for cardiovascular disease in patients treated for coronary heart disease (CHD) at Department of Medicine, Zabok General Hospital during the 2000-2006 period. Cardiovascular diseases are a group of diseases that occur due to arterial. The risk factors that lead to the development and occurrence of cardiovascular disease are hypertension, cigarette smoking, hyperholesterolemia, hypertriglyceridemia, diabetes mellitus and positive family history. Additional factors favoring the occurrence of cardiovascular disease include overweight, inadequate physical activity, and emotional stress. Data on all patients hospitalized and diagnosed with CHD at Department of Medicine, Zabok General Hospital during the 2000-2006 period were analyzed for the prevalence of risk factors for CHD, i.e. hypertension, cigarette smoking, hypercholesterolemia, hypertriglyceridemia, diabetes mellitus and positive family history of cardiovascular disease. Hypercholesterolemia was defined by a cholesterol level higher than 5.1 mmol/L, hypertension from history data and blood pressure measurement on admission greater than 140/90 mmHg, diabetes mellitus from history data, and hypertriglyceridemia by a triglyceride level greater than 1.7 mmol/L. Information on heredity and cigarette smoking was collected from history and a questionnaire filled out on admission. All laboratory values were determined on patient admission to the hospital. Analysis of the risk factors for CHD recorded in patients from Zagorje County during the 2000-2006 period revealed hypertension to be the most common risk factor in our patients. According to sex, CHD was found to show a male preponderance. According to age at admission, CHD predominated in the > 70 age group, which accounted for one third of all patients, followed by a comparable proportion of the 50-60 and 60-70 age groups, i.e. still active population groups. As CHD is one of the leading health threats worldwide, estimated to remain so at least by 2020, it is fully justified to invest all efforts in the study of cardiovascular disease. New research projects should be focused on the prevention and early detection of the disease, improvement of diagnosis procedures, introduction of novel therapeutic options, use of new concepts, and due survey of the measures taken. CHD poses great socioeconomic burden upon every community in industrialized societies because of the ever younger age at onset. Actions should be taken to improve awareness of the CHD risks and morbidity in the population at large, stimulating favorable lifestyle and dietary modifications, and one's own health awareness, in order to upgrade the control of risk factors for and morbidity of cardiovascular disease.     

Sunshine on holidays--eye risks

Ultraviolet (UV) light is the most common cause of radiation injury to the eye which in acute exposure causes photokeratitis and photoconjunctivitis. After a whole day exposure to the sun on the Mediteranian coast patient presented with mixed conjunctival injection, chemosis, edematous corneal epithelium with superficially present fluoresceine positive small pinpoint defects. Epithelial bullous changes, circular stromal infiltration in the middle stromal perifery and reduction of corneal transparency were more pronounced on the left eye. After treatment moderate conjunctival injection remained together with circular stromal infiltration in the middle perifery, corneas were transparent, epithelialised and fluorescein negative. Anterior chambers and lenses were clear. One month after patient regained bilateral visual acuity of 1.0. To our kownledge, this case shows for the first time connection between acute ultraviolet radiation exposure and persistent circular stromal infiltration in the middle corneal perifery in humans.
