War, mental disorder and suicide

War as a human disaster of major significance has led to an increase in the number of suicides committed by people suffering from mental disorders. Considering the results of similar research, we were particularly interested in the effect that war has on the incidence of suicide among of people with mental disorders. The research included 16,362 patients with mental disorders, treated at the Clinic for Psychiatry at the Clinical Hospital Split during the nine-year timeframe which were divided into pre-war (April 6th 1988- April 7rh 1991), wartime (April 6th 1991 -April 7rh 1994) and post-war (April 6th 1997 - April 7th 2000) periods. We studied the effects of how wartime events upon people with mental disorders in terms of their suicide rates, taking into account gender, age group, and the diagnosis under which they were treated. In our research, we found a statistically significant difference in suicide incidence between three observed periods (prewar April 6th 1988 April 7th 1991; wartime April 6th 1991 -April 7th 1994; and postwar April 6th 1997 -April 7th 2000) with the incidence being the highest during the wartime period (chi2 =9.98: p=0.007). Out of 16,362 patients treated at the clinic during the observed timeframe, a total of 78 people committed suicide. Twenty-two patients committed suicide during the first three year pre-war period; 36, during the three year wartime period; and 20, during the third three year post-war period. With this research we intended to offer a better understanding of the complexity of the suicide problem of mental patients as a phenomenon.     

Effectiveness and specificity of a classroom-based group intervention in children and adolescents exposed to war in Lebanon

The purpose of this study was to examine the effectiveness and specificity of a classroom-based psychosocial intervention after war. All students (n=2500) of six villages in Southern Lebanon designated as most heavily exposed to war received a classroom-based intervention delivered by teachers, consisting of cognitive-behavioural and stress inoculation training strategies. A random sample of treated students (n=101) and a matched control group (n=93) were assessed one month post-war and one year later. Mental disorders and psychosocial stressors were assessed using the Diagnostic Interview for Children and Adolescents - Revised with children and parents. War exposure was measured using the War Events Questionnaire. The prevalence of major depressive disorder (MDD), separation anxiety disorder (SAD) and post-traumatic stress disorder (PTSD) was examined pre-war, one month post-war (pre-intervention), and one year post-war. Specificity of treatment was determined by rating teachers’ therapy diaries. The rates of disorders peaked one month post-war and decreased over one year. There was no significant effect of the intervention on the rates of MDD, SAD or PTSD. Post-war MDD, SAD and PTSD were associated with pre-war SAD and PTSD, family violence parameters, financial problems and witnessing war events. These findings have significant policy and public health implications, given current practices of delivering universal interventions immediately post-war.     

Acute coronary syndrome frequency in western Herzegovina over the fifteen year period (1987-2001)

All patients who suffered from the acute coronary syndrome in western Herzegovina over the fifteen year period (1987-2001) are included in this retrospective epidemiological study. The population that was undertaken by the study is relative stabile and did not emigrate during the war period. The study compared the time before the war (1987-1991), during the war (1992-1996) and after the war (1997-2001). The data were acquired from the archives of the patients of the Mostar hospital and Clinical hospital Split during the war period. A total of 2022 acute coronary syndrome patients were found, 1305 men and 717 women. More patients were treated during the war compared to the time before the war for both male and female patients (p<0.0005). During the after-war period the number of treated patients was greater (p< 0.0005) compared to the war-time for both sexes. The comparison of the after-war period and the pre-war period reveals a statistically significant difference as the number of treated patients (male and female) is larger in the after-war period. The number of patient who are 65 years old and older than that is greater, and that is statistically significant (p= 0.0005.). We can conclude that the stress caused by the war and other factors have influenced a larger number of treated patients of acute coronary syndrome. Therefore, further epidemiological researches of acute coronary syndrome with the accent on prevention and treatment are needed.     

Surgical scientific publication and the 1991-1995 war in Croatia

The aim of this study was to evaluate surgical scientific publication in relation to the 1991-1995 war in Croatia, based on the articles indexed in Medline database that were published in 1980-2005 period. The number of articles was extracted from PubMed and analysed with trend analysis, which is preferred analytic approach over calculation of crude publication rates. The results indicate sporadic pre-war output, which was almost completely reduced by the onset of war. During wartime, a significant increasing trend in the number of published surgical articles that were related to warfare was detected (p = 0.003). During the post-war period a gradual shift towards surgical articles that were not related to warfare was detected, also marked by the significant increasing trend (p = 0.027). Both trends were significantly steeper than the overall Croatian biomedical output, suggesting that surgical scientific articles were being published more dynamically than in other biomedical areas in Croatia. The results suggest that war in Croatia has had a strong modifying effect on the surgical scientific output.     

The secular trend in the incidence of hemorrhagic stroke in the region of Osijek,Eastern Croatia in the period 1988-2000--a hospital based study

The purpose of the study was to establish the possible environmental influences in the observed peculiar rising and falling oscillations in the numbers of hemorrhagic stroke (HS) in Eastern Croatia (region of Osijek) during the last thirteen-years' period (1988-2000). In this period 1,222 HS were registered and treated. A constant increase in the incidence of HS was observed, from 60 (in 1988) to 139 (in 1998), with an average annual proportion of 16.5% of all stroke cases. A sharp increase in proportion of HS in total stroke incidence was recorded during the war in Croatia (1991-1995), with a peak incidence of 27.4% in 1993. Typical hypertensive intracerebral hemorrhage (ICH) was the most common (57.1%), atypical ICH occurred in 26.4%, subarachnoid hemorrhage (SAH) in 16.5%. Analysis of the annual number of hypertensive-ICH and SAH disclosed peculiar rising and falling oscillations. These variations were in correlation with heavy living conditions. During the war-period the SAH incidence sharply rose. Immediately after the war it suddenly decreased. The authors named this phenomenon a "pool depletion", supposing the relatively stable proportion of the bearers of aneurysms in population. The observed variations seem to be the consequence of the war stress and other negative psychosocial and economic factors in post-war period, which increases the risk for SAH and typical hypertensive-ICH through complex pathophysiological mechanisms.     

Influence of war circumstances on tumor morphological characteristics in patients with breast cancer

The influence of war circumstances on tumor morphological characteristics in patients with breast cancer has not been studied up to now. The aim of this study is to investigate if war circumstances have influenced breast cancer incidence. The study covered both the patients in which during a period of observation a breast cancer was diagnosed as well as those who died of the same disease in the same period. Three sources of data were used: 1) The archives of the Oncology and Radiotherapy Center of the University Hospital "Split" (UHS): hospital data of 768 patients were reviewed. The war sample consisted of 380 patients aged 59.4+/-12.1 (31 to 86) (including 5 males), whereas the pre-war sample was made up of 388 patients aged 58.4+/-12.7 (19 to 88) (including 3 males); 2) Register of death of the Pathology Department of UHS with 162 analyzed persons whose death was caused by breast cancer in the six-year period between 1988 and 1993. The list of 162 dead patients included 79 people who died from breast cancer diagnosed in that period (1988-1993) and another 83 people that had been diagnosed before that period; 3) The biopsy register of the Pathology Department of UHS with 851 breast biopsies performed between 1988 and 1993. Breast cancer is predominantly a female illness (99.1%). The war circumstances influenced the of T, N and M rate. The rate of N2, N3, Ml were conspicuously higher in the war period. There were significantly more malignant histological diagnoses found in new patients and also significantly more patients died due to breast cancer. Stress and other war circumstances undoubtedly have a negative impact on the numerous markers of breast cancer which we have proved in this study.     

Relative survival analysis of gynecological cancers in an urban district of Shanghai during 2002–2013

ObjectiveAppraisal of cancer survival is essential for cancer control, but studies related to gynecological cancer are scarce. Using cancer registration data, we conducted an in-depth survival analysis of cervical, uterine corpus, and ovarian cancers in an urban district of Shanghai during 2002–2013.Materials and methodsThe follow-up data of gynecological cancer from the Changning District of Shanghai, China, were used to estimate the 1–5-year observed survival rate (OSR) and relative survival rate (RSR) by time periods and age groups during 2002–2013. Age-standardized relative survival rates estimated by the international cancer survival standards were calculated during 2002–2013 to describe the prognosis of cervical, uterine corpus, and ovarian cancers among women in the district.ResultsIn total, 1307 gynecological cancer cases were included in the survival analysis in the district during 2002–2013. Among gynecological cancers, the 5-year OSRs and RSRs of uterine corpus cancer were highest (5-year OSR 84.40%, 5-year RSR 87.67%), followed by those of cervical cancer (5-year OSR 73.58%, 5-year RSR 75.91%), and those of ovarian cancer (5-year OSR 53.89%, 5-year RSR 55.90%). After age adjustment, the 5-year relative survival rates of three gynecological cancers were 71.23%, 80.11%, and 43.27%, respectively.ConclusionThe 5-year relative survival rate did not show a systematic temporal trend in cervical cancer, uterine cancer, or ovarian cancer. The prognosis in elderly patients was not optimistic, and this needs a more advanced strategy for early diagnosis and treatment. The age structure of gynecological cancer patients in the district tended to be younger than the standardized age, which implies that more attention to the guidance and health education for the younger generation is needed.     

Presence of interleukin 10 (IL-10) in the ascites of patients with ovarian and other intra-abdominal cancers.

Typically, ovarian cancer remains restricted to the peritoneal cavity. Because of this unique localization, the study of ovarian cancer is particularly suitable for immune analysis and for the development of immunotherapy. Here we report that peritoneal fluid from patients with ovarian or other intra-abdominal cancers contained significantly elevated levels of interleukin 10 (IL-10) (542 +/- 77 pg/ml, N = 35), compared with peritoneal fluid from patients with benign gynecological conditions (34.2 +/- 7.5 pg/ml, N = 63) (P < 0.001). Peritoneal fluid IL-10 levels did not correlate with histology, tumor stage, grade, or prognosis. IL-10 levels were also elevated in the serum of patients with intra-abdominal cancer (1353 +/- 906, N = 8). Established ovarian cancer cell lines (N = 5) did not produce any detectable IL-10. Investigation of the cell surface phenotype of the cells in the peritoneal cavity indicated the presence of significant amounts of activated immune cells. The presence of cytokines such as IL-10 in the peritoneal cavity of ovarian cancer bearing patients could be important in the growth and development of cancer, more specifically, in relation to host immune responsiveness.     

Increasing incidence and survival of corpus uteri cancer in Estonia over the past two decades

BackgroundCorpus uteri cancer has become the fourth most common female cancer in Europe. In Estonia, the prevalence of obesity is increasing, and corpus uteri cancer survival has been relatively low. The aim of the study was to evaluate incidence, mortality and survival trends of corpus uteri cancer in Estonia by age, stage and histological subtypes with an emphasis on surgical treatment.MethodsEstonian Cancer Registry data on incident cases of corpus uteri cancer were used to examine incidence trends (1995–2016) and calculate relative survival ratios (RSR) (1996–2016). Cases were classified by morphology and FIGO stage. Causes of Death Registry data were used to analyse corrected mortality (1995–2017).ResultsA total of 4281 cases were diagnosed in 1996–2016. A significant increase was seen in age-standardized incidence from 2009, while mortality remained stable throughout the study period. Significant increases were observed for type I cancers and age groups ≥65 years. Overall age-standardized 5-year RSR improved from 70% in 1996–2002 to 78% in 2010–2016. Survival increased for type I cancers, all age groups and all stages (significantly for stage IV). The proportion of surgically treated cases increased significantly from 85% to 89%, with the largest increases seen in older age groups and later stages.DiscussionThe rising corpus uteri cancer incidence in Estonia is driven by the type I cancer trend. Survival gain for later stages and older age groups likely reflected more frequent surgical treatment. To reduce mortality, further efforts are necessary to ensure appropriate care for all patients.     

Role of screening in detection of clinically localized prostate cancer

The aim of this study was to confirm the role of screening by determining the percentage of clinically localized prostate cancer (stage A and B) in patients with prostate cancer detected on screening and in those presenting to urologic clinic for the symptoms of urination impairment or ostalgia. During the study, 1,000 men aged > or = 50 from the community of Cepin and village of Josipovac near Osijek were examined. The subjects with elevated concentration of total prostate specific antigen and/or digital rectal examination suspect of carcinoma underwent transperineal biopsy of the prostate. Clinical staging was performed in patients with prostate cancer detected on screening, and data on clinical staging for prostate cancer patients treated during the 1996-1997 period were retrieved from patient files of the Department of Urology, University Hospital "Osijek". On screening, 28 (80%) patients with localized prostate cancer and seven (20%) patients with metastases were detected. In the group of patients examined on an outpatient basis for the signs and symptoms of prostatism, there were 30 (83.4%) patients with metastases and only six (16.6%) patients with localized prostate cancer. Study results indicated that an early diagnosis of prostate cancer could be made by use of noninvasive and inexpensive methods that cause no major discomfort to the patient. Accordingly, these results appear to strongly support such screening in men, if not in all those aged over 50, then at least in the otherwise healthy, 50-70 age group.     

Uterine cancers in Alberta: trends of incidence and mortality.

Death certificates were reviewed for the 543 Alberta women who died during the period 1969 through 1978 and for whom the underlying cause of death was coded as uterine cancer. To evaluate the recorded cause of death Alberta Cancer Registry records, which existed for 97% of the women, were examined. Calculations from the revised information showed an increase in the mortality of cancer of the corpus uteri and a decrease in the mortality of cancer of the cervix uteri over the 10-year period, but neither was statistically significant. During the same period in Alberta the incidence of cancer of the corpus uteri increased significantly and the incidence of cancer of the cervix uteri decreased significantly.     

Micronuclei level in exfoliated buccal mucosa cells of patients with benign and malignant tumors of female reproductive organs and breast

Micronucleus (MN) levels in exfoliated buccal mucosa cells of primary breast, cervix and corpus uteri cancer patients, and patients with benign tumors of uterus (myoma) and breast (fibroadenoma) were studied. Significantly increased number of MN in cells of cancer patients was observed compared to both healthy persons and patients with benign tumors. In patients with benign tumors no increase in MN quantity was observed. The evaluation of MN number in buccal mucosa cells shows genomic instability caused by malignant tumor in somatic cells of humans.     

Effects of the GnRH analogue deslorelin implants on reproduction in female domestic cats

The aim of the present study was to investigate the safety and efficacy of deslorelin, a GnRH agonist, implants in suppressing estrus behavior and matings in a controlled ambient environment in feline queens in the presence of a tomcat. Local and utero-ovarian side effects of deslorelin implants were also investigated. The queens were housed in groups and assigned to one of three treatments: group 1 received 9.5 mg deslorelin implants (N = 14), group 2 received 5 mg megestrol acetate tablets and 9.5 mg deslorelin implants (N = 7), and group 3 were given placebo implants (N = 7). All implants were placed subcutaneously cranial to the interscapular region under xylazine hydrochloride sedation. Ovarian activity was monitored by fecal estradiol (E₂) analyses. The animals were observed daily and checked individually at three-day intervals for behavioral signs of estrus. After 18.5 mo of trial, queens were ovariohysterectomized, and ovaries and uteri were weighed and evaluated histologically. E₂ levels were significantly lower in group 1 and 2 than in group 3 with an average of 128.48 ± 19.97 ng/g, 90.44 ± 7.16 ng/g and 283.26 ± 39.21 ng/g, respectively, excepting the first week of treatment. After inserting implants an initial estrus-like increase in fecal E₂ concentrations occurred in all treated queens except one female in group 2. Ovarian and uterine weights were significantly different among the groups (P < 0.01), and were lowest in groups 1 and 2. Primordial and primary follicle numbers were significantly higher in groups 1 and 2 than in group 3 (P < 0.001). Endometrial gland, antral follicle, and corpus luteum (CL) numbers were highest in group 3 (P < 0.01, 0.001, and 0.001, respectively) compared with groups 1 and 2. Deslorelin implants successfully suppressed estrus behavior and E₂ secretion in queens for 18.5 mo of the study period. Further investigations are needed to demonstrate the effects of GnRH agonists on ovarian interstitial tissue.     

Scope and limitations of MALDI-TOF MS blood serum peptide profiling in cancer diagnostics

Serum samples (33 healthy women, 34 ovarian cancer, 28 colorectal cancer, 34 syphilis patients and 136 patients with various benign gynecological diseases) were analyzed by MALDI-TOF MS peptide profiling and respective predictive models were generated by genetic and supervised neural network algorithms. Classification models for pathology versus healthy control showed up to 100% sensitivity and specificity for all target diseases. However, the specificity dropped to unsatisfactory 25–40% in case of target versus nontarget disease diagnostics. Expansion of the control group to an artificial “nominal control” group by adding profiles of benign gynecological diseases considerably improved specificity of the models distinguishing ovarian cancer from healthy control and benign gynecological diseases. The suggested version of MALDI-TOF MS profiling of sera could be applied to differentiate between cancers and benign neoplasms of the same localization which is a challenging task for classical methods. To increase the specificity of diagnostic methods based on peptidome analysis of blood samples, it is necessary to identify sets of concrete peptide structures which qualitatively or quantitatively differ among patients with different diseases.     

Improvement of long-term prognosis in patients with ovarian cancers by adjuvant sizofiran immunotherapy: a prospective randomized controlled study

The effect of immunotherapy using sizofiran (SPG) on the prognosis of patients with ovarian cancers was prospectively studied in a total of 68 patients, who were randomly assigned to either a cisplatin, adriamycin and cyclophosphamide (PAC) therapy group or a PAC plus SPG combination therapy group.The survival rate was significantly higher in patients with stage Ic, II or III cancers treated with the PAC plus SPG combination, compared with the patients treated with PAC alone. In the SPG-receiving patients with stage Ic or more advanced cancers who were treated with four cycles or more of PAC, the outcome was improved (Cox-Mantel, p=0.074; generalized Kruskal-Wallis, p=0.032). Similar improvement was also observed in the patients with non-serous adenocarcinomas (Cox-Mantel, p-0.076; generalized Krukal-Wallis, p=0.045). No side effects attributable to SPG were recorded.The present results suggest that the use of SPG in combination with long-term chemotherapy improves the postoperative prognosis in ovarian cancer patients.Abbreviations SPG sizofiran     

Antitumor effects of combination toremifene and medroxyprogesterone acetate (MPA) in vitro and in vivo

The estrogen (ER) and progesterone (PgR) receptor levels in various gynecological tumors were measured. The same tumors were exposed in vitro to toremifene, MPA or their combination and the growth of the tumors was followed by measuring the adenosine triphosphate (ATP) within the cells by a simple bioluminescence assay. Altogether 34 clinical samples were studied. DMBA-induced mammary tumors bearing rats were treated in vivo with toremifene, MPA and their combination. About half of the ovarian cancers and 6 out of the 7 adenocarcinomas of uteri contained ER. The ovarian tumors were PgR rich in 25% and adenocarcinomas of uteri in 6 out of the 7 cases. When compared to control toremifene (concentration 1 mumol/l) was able to decrease the number of living cells to 50% or less in 9/34 samples, MPA (concentration 10 mumol/l) in 17/34 samples, and the combination in 25/34 samples. In five cases the antitumor effect of the combination was synergistic. In two cases signs of weak antagonism were seen. In vivo the antitumor effect of toremifene and MPA was clearly synergistic against DMBA-induced cancers. The effect was dose-dependent and at sufficiently high doses it was possible to eradicate the tumors and cure the animals.     

Effect of the stage of pregnancy and post-partum on the number of gonadotrophin responsive follicles in ewes

The present study was designed to study follicular growth and its interactions with the corpus luteum of pregnancy in sheep during early, middle and late pregnancy and during postpartum anestrus. Ewes with 1 or 2 corpora lutea in one ovary were selected from a larger group of Serres ewes. All pregnant ewes were randomly allocated to two groups, with 10 to 12 ewes per group. Ewes of Group I were treated with 750 IU hCG at Day 25 or 45 or 70 or 100 or 125 of pregnancy. In Group II, ewes were treated with a combination of 1000 IU PMSG + 750 IU hCG either at Day 25 or 45 or 70 or 100 of pregnancy. The results demonstrated the presence of gonadotrophin-responsive follicles during early pregnancy (Days 25 to 45), reduction of their number during mid-pregnancy (Days 70 to 100), and their disappearance during late pregnancy (Day 125). Administration of hCG to Serres ewes at 10 and 20 days postpartum induced ovulation of a high proportion of ewes at 10 days postpartum (62%) with a further increase observed at 20 days postpartum (75%). During pregnancy, as well as during the postpartum period, there was no significant difference in the number of ovulations induced according to the location of the corpus luteum of pregnancy. These data demonstrate that the presence of the corpus luteum of pregnancy does not affect the number of gonadotrophin-responsive follicles until Day 100 of pregnancy. However, during late pregnancy such follicles were no longer present in the ovaries. Gonadotrophin-responsive follicles were again present as soon as Day 10 postpartum.     

Reliability of recording uterine cancer in death certification in France and age-specific proportions of deaths from cervix and corpus uteri

French uterine cancer recordings in death certificates include 60% of "uterine cancer, Not Otherwise Specified (NOS)"; this hampers the estimation of mortalities from cervix and corpus uteri cancers. The aims of this work were to study the reliability of uterine cancer recordings in death certificates using a case matching with cancer registries and estimate age-specific proportions of deaths from cervix and corpus uteri cancers among all uterine cancer deaths by a statistical approach that uses incidence and survival data. Deaths from uterine cancer between 1989 and 2001 were extracted from the French National database of causes of death and case-to-case matched to women diagnosed with uterine cancer between 1989 and 1997 in 8 cancer registries. Registry data were considered as "gold-standard". Among the 1825 matched deaths, cancer registries recorded 830 cervix and 995 corpus uteri cancers. In death certificates, 5% and 40% of "true" cervix cancers were respectively coded "corpus" and "uterus, NOS" and 5% and 59% of "true" corpus cancers respectively coded "cervix" and "uterus, NOS". Miscoding cervix cancers was more frequent at advanced ages at death and in deaths at home or in small urban areas. Miscoding corpus cancers was more frequent in deaths at home or in small urban areas. From the statistical method, the estimated proportion of deaths from cervix cancer among all uterine cancer deaths was higher than 95% in women aged 30-40 years old but declined to 35% in women older than 70 years. The study clarifies the reason for poor encoding of uterus cancer mortality and refines the estimation of mortalities from cervix and corpus uteri cancers allowing future studies on the efficacy of cervical cancer screening.     

The effect of the civil war on Rwandas bean seed systems and unusual bean diversity

The Rwandan civil war escalated in 1994, killing 800 000 people and displacing another 2 million. Agriculture, the occupation of over 90% of the Rwandans was acutely affected as violence peaked in the middle of the growing season. This article analyses the effects of the war on bean varietal diversity as, pre-war, Rwandan farmers grew the greatest range of varieties in active use anywhere and maintaining such diversity was central to sustainable production. Extensive pre- and post-war assessments show the current bean varietal situation to be relatively promising. The war had lesser effects than anticipated: fighting was staggered, harvests were better than expected, and local seed channels generally continued functioning. However, changes in varietal profiles were noted over the longer term due to two trends: farmers' needs to intensify production and to respond to swift and widespread root rot pressures. The article ends with five methodological reflections on how to assess varietal erosion in sites of acute disruption.
