Abstract
BACKGROUND It has been claimed that COVID-19 vaccination is associated with excess mortality during the COVID-19 pandemic, a claim that contributes to vaccine hesitancy. We examined whether all-cause mortality has actually increased in Cyprus during the first two pandemic years, and whether any increases are associated with vaccination rates. METHODS We calculated weekly excess mortality for Cyprus between January 2020 and June 2022, overall and by age group, using both a Distributed Lag Nonlinear Model (DLNM) adjusted for mean daily temperature, and the EuroMOMO algorithm. Excess deaths were regressed on the weekly number of confirmed COVID-19 deaths and on weekly first-dose vaccinations, also using a DLNM to explore the lag-response dimension. RESULTS 552 excess deaths were observed in Cyprus during the study period (95% CI: 508-597) as opposed to 1306 confirmed COVID-19 deaths. No association between excess deaths and vaccination rates was found overall and for any age group except 18-49 years, among whom 1.09 excess deaths (95% CI: 0.27-1.91) per 10,000 vaccinations were estimated during the first 8 weeks post-vaccination. However, detailed cause-of-death examination identified just two such deaths potentially linked to vaccination, therefore this association is spurious and attributable to random error. CONCLUSIONS Excess mortality was moderately increased in Cyprus during the COVID-19 pandemic, primarily as a result of laboratory-confirmed COVID-19 deaths. No relationship was found between vaccination rates and all-cause mortality, demonstrating the excellent safety profile of COVID-19 vaccines.

Abstract
Abstract
Background
In Cyprus, breast cancer (BC) is the first in incidence and second in mortality cancer in women. A national screening programme (NSP), targeting women 50-69 years, was introduced in 2007. The aim of this study is to provide a better understanding of cancer trends.
Methods
Data from the national population-based Cyprus Cancer Registry on adult women diagnosed with BC between 2004-2017 with follow-up until 2019 were analysed as follows: Joinpoint regression for age-adjusted (overall and by tumor stage at diagnosis - TSD) and age-specific rates (<50, 50-59, 60-69, 70-79, ≥ 80) incidence and mortality rates; 5-year age-adjusted Net Survival (NS) rates, overall and by TSD. TSD was categorised as localised, regional, and distant.
Results
Age-adjusted incidence rate increased from 135.3 (2004) to 153.2 (2017) per 100,000, with an annual percentage change (APC) of 1.1% (95%CI: 0.4-1.9). The greatest increase was in the age groups ≥70 years. A positive time trend was found for localized cancers between 2006-2017, while for all other stages nonsignificant trends were detected. Age-adjusted mortality rate increased from 37.0 (2004) to 50.0 (2019) per 100,000 (APC: 2.7%; 95%CI: 1.9-9.4). Significant increases in mortality rates were detected in the age groups ≥70 years. By TSD, increased rates were found at localised and regional stages, however smaller increases were detected since 2007. NS rates for the most recent period (2014-2017) was 93% for localized, 81% for regional, and 32% for distant and did not significantly improve compared to the previous years.
Conclusions
Trends in BC incidence continues to increase, especially in the older age groups and for early-stage cancers. As expected, since the introduction of the NSP, the incidence of localised cancers increased whilst the incidence of advanced stage cancer decreased, albeit non-significantly. Survival trends did not change but mortality rates for localised and regional cancers increased at a slower pace.
Key messages
• The introduction of the national screening programme may have played an important role in the increasing BC incidence trends.
• Despite survival rates not improving since the introduction of the national screening programme, mortality rates for early-stage cancers show a less steep increase.

Abstract
BACKGROUND Despite its rarity, cancer in children and adolescents (CAC) is a major health issue worldwide. The lack of appropriate cancer registries is an obstacle for defining its incidence and survival, and informing cancer control. As in Cyprus, CAC epidemiology has not previously been comprehensively examined, we determined incidence rates and temporal trends of cancer in the 0-19 age group during 1998-2017. METHODS We established the population based Paediatric Oncology Registry of Cyprus (PORCY) for the period 1998-2017. World age standardised incidence rate per million children and adolescents per year (ASRW) were calculated and time trends were assessed using Joinpoint regression analysis. Comparisons were made with other countries using the International Incidence of Childhood Cancer, third volume. RESULTS For all cancers combined, for ages 0-19-years, ASRW was 203.54 (95% CI 189.49, 217.59) one of the highest rates globally. The most frequent CAC were leukaemias followed by lymphomas, specified epithelial neoplasms and central nervous system tumours, differing to what is described in most other countries. For all cancers, both combined and individual types, except thyroid carcinoma (where incidence was rising), no significant temporal variation was found. CONCLUSIONS To inform cancer control activities, we conducted the first ever population-based epidemiological study of childhood and adolescent cancer (0-19 years) in Cyprus. The striking findings indicate high overall incidence rates that are among the world's highest, a higher frequency of lymphomas and thyroid cancer than brain tumours, and rising incidence for thyroid, but not for other, cancers. These novel findings, will help the formulation of hypotheses to provide explanation for the high rates for all CAC in Cyprus and may contribute to the global efforts for improving prevention of cancer in this age group.

Abstract
Objectives We explored the effectiveness of COVID-19 vaccines in preventing reinfection in the Republic of Cyprus. Study design This was a matched case–control study (1:2). Methods Cases were adults with a first episode of SARS-CoV-2 infection in 2020 and a second episode (i.e. reinfection) between June and August 2021. Controls were adults with only one infection episode in 2020 (i.e. not reinfected). Matching was performed by age, gender, and week of diagnosis for the first episode. The reinfection date of a case was applied to the matched controls for estimating full or partial vaccination status. Cases and controls were classified as unvaccinated, partially vaccinated (i.e. vaccination series not completed or final dose received ≤14 days before the reinfection date), or fully vaccinated (i.e. final dose received >14 days before the reinfection date). Conditional logistic regression was performed to calculate odds ratios and 95% confidence intervals for full or partial vaccination, against no vaccination, between controls and cases. Results This study showed that controls were more likely to be vaccinated (odds ratio for full vaccination: 5.51, 95% confidence interval: 2.43–12.49) than cases. Conclusions This finding answers a pressing question of the public and supports the offer of vaccination to people with previous SARS-CoV-2 infection.

Abstract
The current COVID-19 crisis has changed our everyday lives almost in every aspect. Many people worldwide have died or hospitalised due to the severe impact of COVID-19 on the vulnerable population, and in particular to the elderly residents of long term care facilities (LTCF). The problem is amplified due to the fact that many of those occupants also suffer from comorbidities (e.g. respiratory and cardiovascular diseases, hypertension, etc.) and are therefore regarded as a susceptible host to severe COVID-19 disease. Impacts can be felt in the wider societal safety level. The aim of the present study is, therefore, to present the first National multimodal quality and safety improvement strategy plan for the LTCF in the Republic of Cyprus. The current program focused on the intensification of COVID-19 epidemiological surveillance, the promotion of educational training on best practises in infection control and prevention, and the implementation of additional non-pharmaceutical interventions (NPIs), according to the recommendations of ECDC (European Centre for Disease Prevention and Control) and WHO (World Health Organization). This innovative program fostered the interconnectivity and collaboration among the local authorities, academia and the local leaders of the LTCF. In addition, this program reinforced the importance of volunteerism and active participation of medical students in the National initiatives against the COVID-19 pandemic. The effectiveness of the adopted multimodal advanced care-safety planning program is appraised based on the reported new confirmed COVID-19 cases among LTCF healthcare workers and occupants, after the introducing and implementation of the selected NPIs. This multimodal strategy plan seems to be capable of reducing significantly the number of new cases of COVID-19 infections in LTCF and as a result, to also affect the residents' death number.

Abstract
BACKGROUND Hepatitis C virus (HCV) infection is a major global public health problem. In the Republic of Cyprus, the estimated prevalence of chronic hepatitis C (CHC) among the general population is 0.6%, while the CHC prevalence among people who inject drugs (PWID) is estimated at 46%. Direct-acting antivirals that can eliminate HCV are not yet widely available in the Republic of Cyprus. However, when direct-acting antivirals become available, a long-term strategic plan to guide elimination efforts will be needed to maximize the effect of treatment.
AIM To determine the programmatic targets to eliminate HCV in the Republic of Cyprus.
METHODS A dynamic, stochastic, individual-based model of HCV transmission, disease progression, and cascade of care was calibrated to data from Cyprus. The model stratifies the population into the infected general population and the PWID population. A variety of test, prevention, and treatment strategies concerning the general population, PWID, or both were examined. The time horizon of the analysis was until 2034.
RESULTS Under the status quo scenario, the model predicted that 75 (95% confidence interval (CI): 60, 91) and 575 (95%CI: 535, 615) liver-related deaths and new infections would occur by 2034, respectively. Launching an expanded treatment program, without screening interventions, would cause modest outcomes regarding CHC prevalence (16.6% reduction in 2034 compared to 2020) and liver-related deaths (10 deaths would be prevented compared to the status quo scenario by 2034). Implementing a test and treat strategy among the general population but without any intervention in the PWID population would suffice to meet the mortality target but not the incidence target. To achieve HCV elimination in Cyprus, 3080 (95%CI: 3000, 3200) HCV patients need to be diagnosed and treated by 2034 (2680 from the general population and 400 from PWID), and harm reduction coverage among PWID should be increased by 3% per year (from 25% in 2020 to 67% in 2034).
CONCLUSION Elimination of HCV is a demanding public health strategy, which requires significant interventions both among the general population and high-risk groups.

Abstract
BACKGROUND Paediatric and adolescent thyroid cancer incidence rates are increasing in many countries. We determined incidence rates, temporal trends and survival from thyroid cancer diagnosed in childhood and adolescence in Cyprus during 1998-2017. METHODS Patients aged 0-19 years, diagnosed with thyroid cancer in the Pediatric Oncology Registry of Cyprus were included. Crude incidence rates, age standardized rates, time trends and overall survival were analysed. Annual rates and temporal trends were calculated using Microsoft Excel 2016 and Joinpoint regression analysis. RESULTS Eighty-one cases (76.5 % female, 23.5 % male) were identified. The crude rates (per 100,000 persons) were for both sexes 2.00 (95 % CI 1.61, 2.49), females 3.15 (95 % CI 2.45, 4.03) and males 0.92 (95 % CI 0.58, 1.44). The annual percentage changes of crude and standardised rates were 7.5 % (p < 0.05) and 7.6 % (p < 0.05). The annual percentage changes of crude rates were for females 5.1 % (p = 0.1), males 8.4 % (p < 0.05) and 15-19-year-olds 7.6 % (p < 0.05). The female to male rate ratio was 3.42 (95 % CI 2.06, 5.74). Papillary thyroid carcinoma represented 86.4 % of all cases. There was only one case after previous cancer therapy. The rate ratio of 2nd (2008-2017) to 1st (1998-2007) periods for metastatic (regional) stages was 3.76 (95 % CI 1.74, 8.31). Survival until 2018 was 100 %. CONCLUSION This population-based study demonstrated that thyroid cancer incidence rates in 0-19-year-olds in Cyprus was among the world's highest. Increasing trends mainly affected males and females aged 15-19 years with papillary thyroid carcinoma, the dominant type. Cases after previous cancer therapy didn't contribute to increasing rates. The increase of metastatic cases suggests a true increase of thyroid cancer rather than overdiagnosis. Although prognosis is excellent with 100 % survival, the rising incidence rate is unexplained, indicating the need to identify causes.

Abstract
Background Despite progress in the management of invasive meningococcal disease (IMD) it causes significant mortality and sequelae. Aim This study aims to describe the epidemiology and clinical characteristics of IMD in Cyprus and discuss the current immunisation programmes. Methods This is a retrospective study of all cases of IMD notified to the Ministry of Health between 2004 and 2018. Demographic, epidemiological, clinical and microbiological data were collected when a new case was notified. Risk factors associated with mortality were investigated using univariable logistic regression. Results 54 cases of IMD were recorded, an overall incidence of 0.4 cases per 100,000 population. The incidence rate was highest among infants (7.2/100,000) and adolescents (1.4/100,000). Case fatality rate was 10.4%. Serogroup B accounted for 24 of 40 cases caused by known serogroup. Serogroups W and Y comprised nine cases and were responsible for most fatal cases. Serogroup C was the cause in only four cases. There was an increase in the odds of death with increasing age, while the presence of meningitis in the clinical picture was found to be associated with lower odds of death. Conclusion Despite the low incidence of IMD in Cyprus, it remains an important cause of morbidity and mortality. Serogroup B is the most frequent serogroup, while incidence of serogroups W and Y is rising. Monitoring new cases and yearly evaluation of the immunisation programmes by the National Immunization Technical Advisory Group (NITAG) is essential for successful control of the disease.

Abstract
Coronavirus disease 2019 (COVID-19) has significantly affected the well-being of individuals worldwide. We herein describe the epidemiology of COVID-19 in the Republic of Cyprus during the first epidemic wave (9 March-3 May 2020). We analyzed surveillance data from laboratory-confirmed cases, including targeted testing and population screening. Statistical analyses included logistic regression. During the surveillance period, 64,136 tests (7322.3 per 100,000) were performed, 873 COVID-19 cases were diagnosed, and 20 deaths were reported (2.3%). Health-care workers (HCWs) represented 21.4% of cases. Overall, 19.1% of cases received hospital care and 3.7% required admission to Intensive Care Units. Male sex (adjusted Odds Ratio (aOR): 3.04; 95% Confidence Interval (CI): 1.97-4.69), increasing age (aOR: 1.56; 95%CI: 1.36-1.79), symptoms at diagnosis (aOR: 6.05; 95%CI: 3.18-11.50), and underlying health conditions (aOR: 2.08; 95%CI: 1.31-3.31) were associated with hospitalization. For recovered cases, the median time from first to last second negative test was 21 days. Overall, 119 primary cases reported 616 close contacts, yielding a pooled secondary attack rate of 12% (95%CI: 9.6-14.8%). Three population-based screening projects, and two projects targeting employees and HCWs, involving 25,496 people, revealed 60 positive individuals (0.2%). Early implementation of interventions with targeted and expanded testing facilitated prompt outbreak control on the island.

Abstract
Abstract
Background
A national breast cancer (BC) screening programme, targeting women 50-69 years old, was introduced in Cyprus in 2007. This study aims to assess rural/urban differences in BC incidence, tumour stage at diagnosis (TSD) and mortality, since 2004 and since the introduction of the screening programme.
Methods
Data were obtained for 6589 new cases of BC (diagnosis 2004-2016) from a national population-based cancer registry (1998-today) in Cyprus. TSD was recorded according to the Surveillance, Epidemiology, and End Results categories. We defined late TSD as regional or distant stage. Unknown stages were excluded. We linked cases to the population census data and place of residence (rural/urban) and calculated incidence and mortality rate ratios (RR) by place of residence. We conducted logistic regression to measure the association between place of residence and TSD or mortality, adjusting for sex, age, ethnicity, smoking and marital status. Adjusted odds ratios (aOR) and 95% confidence intervals (CI) are reported.
Results
Since 2004, 54.7% of BC cases were diagnosed at localised stage, 40.6% at regional stage and 4.7% at distant stage. Incidence, but not mortality, rate for all BC was higher in urban than in rural areas (RRincidece=1.22;95%CI=1.51-1.28 and RRmortality=1.10;95%CI=0.97-1.24). Rural place of residence was associated with higher odds of late TSD (aOR=1.34; 95%CI=1.15-1.58) and death (aOR=1.36; 95%CI=1.11-1.68). After the introduction of the screening programme, for the targeted age group, rural place of residence was still associated with higher odds of late TSD (aOR=1.31; 95%C= 1.03-1.67), but not with death (p > 0.05).
Conclusions
Even though BC incidence is higher in urban than in rural areas, women residing in rural areas had higher odds of late TSD and death. The introduction of the national BC screening programme only slightly reduced geographical inequalities in TSD. Further studies are needed to understand and reduce the role of inequalities in TSD.
Key messages
Rural/Urban inequalities in TSD are evident among BC cases in Cyprus, diagnosed between 2004 and 2016. The introduction of the national BC screening programme reduced but did not overcome geographical inequalities in TSD.

Abstract
Season of birth, a surrogate of seasonal variation of environmental exposures, has been associated with increased risk of several cancers. In the context of a Southern-Eastern Europe (SEE) consortium, we explored the potential association of birth seasonality with childhood (0-14 years) central nervous system (CNS) tumors. Primary CNS tumor cases (n = 6,014) were retrieved from 16 population-based SEE registries (1983-2015). Poisson regression and meta-analyses on birth season were performed in nine countries with available live birth data (n = 4,987). Subanalyses by birth month, age, gender and principal histology were also conducted. Children born during winter were at a slightly increased risk of developing a CNS tumor overall [incidence rate ratio (IRR): 1.06, 95% confidence intervals (CI): 0.99-1.14], and of embryonal histology specifically (IRR: 1.13, 95% CI: 1.01-1.27). The winter peak of embryonal tumors was higher among boys (IRR: 1.24, 95% CI: 1.05-1.46), especially during the first 4 years of life (IRR: 1.33, 95% CI: 1.03-1.71). In contrast, boys <5 years born during summer seemed to be at a lower risk of embryonal tumors (IRR: 0.73, 95% CI: 0.54-0.99). A clustering of astrocytomas was also found among girls (0-14 years) born during spring (IRR: 1.23, 95% CI: 1.03-1.46). Although the present exploratory results are by no means definitive, they provide some indications for age-, gender- and histology-related seasonal variations of CNS tumors. Expansion of registration and linkage with cytogenetic reports could refine if birth seasonality is causally associated with CNS tumors and shed light into the complex pathophysiology of this lethal disease.

Abstract
BACKGROUND A significant disparity regarding survival outcome for melanoma among European regions is well recognized and access to high quality care for European melanoma patients needs to be improved. There is an unmet need for the implementation of minimal standard of care within defined clinical pathways and Quality Assurance (QA) indicators. OBJECTIVE The EU-MELACARE study aims to identify shared variables for cutaneous melanoma cases recorded in melanoma registries across Europe. MATERIAL AND METHODS Opinion leaders involved in melanoma data registration and care quality analysis in 34 European countries were invited to respond to an expert survey covering questions regarding the melanoma registration practice in their countries and the characteristics, coverage and variables collected by the relevant melanoma registries. RESULTS Data regarding 13 melanoma registries from 11 European countries contributed to the study. The majority (61,5%) were population based registries and more than half (62%) had national coverage. The included registries collected a median of 38 variables (Interquartile Range, IRQ 21-76). We identified 24 shared variables available in >70% of registries. CONCLUSIONS This study provides valuable specific information on information recorded for melanoma cases are registered within Europe. A core of shared variables has been identified, which will constitute the basis for a standardized set of QA indicators for assessing and monitoring melanoma care across European countries.

Abstract
BACKGROUND/AIMS There are wide variations in colorectal cancer (CRC) incidence across the world. Historically, the highest incidence rates have been reported historically in more developed countries; however, increasing trends have been seen in developing countries. Here, we present the CRC incidence pattern in Cyprus, Israel, Jordan, and İzmir, Turkey, which are countries of the Middle East Cancer Consortium (MECC). MATERIALS AND METHODS We analyzed 2005-2010 CRC data from population-based registries and calculated crude and age standardized rates for CRC, colon and rectum subsites, and annual percent changes (APCs) for trends. RESULTS The age-adjusted incidence rates (AAIRs) for CRC were the highest in Israeli Jews (IJ) (46.7 for males and 35.5 for females), which exceeded those of the USA Surveillance, Epidemiology, and End Result (SEER) program registries. In both sexes, AAIRs in Cyprus and Israeli Arabs (IA) were close to those in SEER registries. For both sexes, AAIRs in İzmir and Jordan were substantially lower than those in other registries. Statistically significant decreasing trends over time were observed in AAIRs for both sexes in the SEER program (APCs: males, -3.24% and females, -2.54%), whereas the trends varied within the MECC registries. There were decreasing AAIR trends for males in IJ and IA and for females in Cyprus and IJ; APC for females in IJ (-4.29%) was significant. Conversely, increasing trends with the significant APCs were observed in males in İzmir (2.43%) and Jordan (7.57%). CONCLUSION MECC countries comprise both high- and low-risk populations for CRCs. However, increasing trends in low-risk populations have been alarming. Thus, the need for implementing tailored primary and secondary prevention programs in the region is essential.

Abstract
BACKGROUND Despite recent therapeutic advancements, Wilms tumour (WT) presents remarkable survival variations. We explored mortality and survival patterns for children (0-14 years) with WT in 12 Southern and Eastern European (SEE) countries in comparison with the United States of America (USA). METHODS A total of 3966 WT cases (0-14 years) were registered by a network of SEE childhood cancer registries (N:1723) during available registration periods circa 1990-2016 and surveillance, epidemiology, and end results program (SEER) (N:2243; 1990-2012); mortality data were provided by the respective national statistical services. Kaplan-Meier curves and Cox proportional hazards models were used to assess the role of age, sex, year of diagnosis, urbanisation and Human Development Index (HDI) on overall survival (OS). RESULTS Persisting regional variations shape an overall 78% 5-year OS in the participating SEE countries, lagging behind the USA figure (92%, p=0.001) and also reflected by higher SEE mortality rates. Worth mentioning is the gradually escalating OS in SEE (hazard ratio [HR]5-year increment:0.67, 95% confidence interval [CI]:0.60, 0.75) vs. a non-significant 10% improvement in the SEER data, which had a high starting value. OS differentials [two-fold less favourable among children aged 10-14 years, boys and those living in rural SEE areas (HR:1.37; CI:1.10-1.71) or countries with inferior HDI (2-3-fold)] were minimal in the USA. CONCLUSIONS Children with WT residing in SEE countries do not equally enjoy the substantial survival gains, especially for those living in rural areas and in lower HDI countries. Noteworthy are steep and sizeable survival gains in SEE along with the newly presented Greek data pointing to achievable survival goals in SEE despite the financial crisis.

Abstract
AIM Neuroblastoma outcomes vary with disease characteristics, healthcare delivery and socio-economic indicators. We assessed survival patterns and prognostic factors for patients with neuroblastoma in 11 Southern and Eastern European (SEE) countries versus those in the US, including-for the first time-the Nationwide Registry for Childhood Hematological Malignancies and Solid Tumours (NARECHEM-ST)/Greece. METHODS Overall survival (OS) was calculated in 13 collaborating SEE childhood cancer registries (1829 cases, ∼1990-2016) and Surveillance, Epidemiology, and End Results (SEER), US (3072 cases, 1990-2012); Kaplan-Meier curves were used along with multivariable Cox regression models assessing the effect of age, gender, primary tumour site, histology, Human Development Index (HDI) and place of residence (urban/rural) on survival. RESULTS The 5-year OS rates varied widely among the SEE countries (Ukraine: 45%, Poland: 81%) with the overall SEE rate (59%) being significantly lower than in SEER (77%; p < 0.001). In the common registration period within SEE (2000-2008), no temporal trend was noted as opposed to a significant increase in SEER. Age >12 months (hazard ratio [HR]: 2.8-4.7 in subsequent age groups), male gender (HR: 1.1), residence in rural areas (HR: 1.3), living in high (HR: 2.2) or medium (HR: 2.4) HDI countries and specific primary tumour location were associated with worse outcome; conversely, ganglioneuroblastoma subtype (HR: 0.28) was associated with higher survival rate. CONCLUSIONS Allowing for the disease profile, children with neuroblastoma in SEE, especially those in rural areas and lower HDI countries, fare worse than patients in the US, mainly during the early years after diagnosis; this may be attributed to presumably modifiable socio-economic and healthcare system performance differentials warranting further research.

Abstract
The Global Initiative for Cancer Registry Development partnership, led by the International Agency for Research on Cancer (IARC), was established in response to an overwhelming need for high-quality cancer incidence data from low-income and middle-income countries. The IARC Regional Hub for cancer registration in North Africa, Central and West Asia was founded in 2013 to support capacity building for cancer registration in each of the countries in this region. In this Series paper, we advocate the necessity for tailored approaches to cancer registration given the rapidly changing cancer landscape for this region, and the challenges faced at a national level in developing data systems to help support this process given present disparities in resources and health infrastructure. In addition, we provide an overview of the status of cancer surveillance and activities country-by-country, documenting tailored approaches that are informing local cancer-control policy, and potentially curbing the growing cancer burden across the region.

Abstract
Childhood (0-14 years) lymphomas, nowadays, present a highly curable malignancy compared with other types of cancer. We used readily available cancer registration data to assess mortality and survival disparities among children residing in Southern-Eastern European (SEE) countries and those in the United States. Average age-standardized mortality rates and time trends of Hodgkin (HL) and non-Hodgkin (NHL; including Burkitt [BL]) lymphomas in 14 SEE cancer registries (1990-2014) and the Surveillance, Epidemiology, and End Results Program (SEER, United States; 1990-2012) were calculated. Survival patterns in a total of 8918 cases distinguishing also BL were assessed through Kaplan-Meier curves and multivariate Cox regression models. Variable, rather decreasing, mortality trends were noted among SEE. Rates were overall higher than that in SEER (1.02/106 ), which presented a sizeable (-4.8%, P = .0001) annual change. Additionally, remarkable survival improvements were manifested in SEER (10 years: 96%, 86%, and 90% for HL, NHL, and BL, respectively), whereas diverse, still lower, rates were noted in SEE. Non-HL was associated with a poorer outcome and an amphi-directional age-specific pattern; specifically, prognosis was inferior in children younger than 5 years than in those who are 10 to 14 years old from SEE (hazard ratio 1.58, 95% confidence interval 1.28-1.96) and superior in children who are 5 to 9 years old from SEER/United States (hazard ratio 0.63, 95% confidence interval 0.46-0.88) than in those who are 10 to 14 years old. In conclusion, higher SEE lymphoma mortality rates than those in SEER, but overall decreasing trends, were found. Despite significant survival gains among developed countries, there are still substantial geographic, disease subtype-specific, and age-specific outcome disparities pointing to persisting gaps in the implementation of new treatment modalities and indicating further research needs.

Abstract
It is important that population-based cancer registries provide accurate and reliable data for public health purposes. These data are essential data for planning of cancer control and prevention. In this study, we examined cancer incidence rates (year 2005-2010) in four MECC registries (Cyprus, Jordan, Israel, Izmir (Turkey)) and compared with the rates in the US. The overall age-standardized incidence rates for males were highest in the US followed by Israeli Jews, Izmir (Turkey), Cyprus, Israeli Arabs, and lowest in Jordan. In women the rates of cancer of all sites were also highest in US women followed by Israeli Jews, Cyprus, Israeli Arabs, Izmir (Turkey), and lowest in Jordan. It is of interest that although site-specific cancer rates differ between the countries studied, prostate, lung and colorectal cancers are within the five most common cancers males in all countries studied. In females, breast colorectal and endometrium cancers are three of the five most common cancers in females in all countries studied. The results presented in this paper can have implications for opportunities in cancer control and prevention in these countries. Future studies on individual cancer sites with highest rates in these Countries are currently underway.

Abstract
AIM To assess trends in survival and geographic disparities among children (0-14 years) with chronic myeloid leukaemia (CML) before and after the introduction of molecular therapy, namely tyrosine kinase inhibitors (TKIs) in Southern-Eastern European (SEE) countries and the USA. METHODS We calculated survival among children with CML, acute lymphoblastic (ALL) and acute myeloid leukaemia (AML) in 14 SEE (1990-2014) cancer registries and the U.S. Surveillance, Epidemiology and End Results Program (SEER, 1990-2012). We used Kaplan-Meier curves and multivariate Cox regression models to calculate hazard ratios (HRs) with 95% confidence intervals (CIs). RESULTS Among 369 CML cases, substantial improvements were noted in 2-year survival during the post-TKI (range: 81-89%) compared to pre-TKI period (49-66%; HR: 0.37, 95% CI: 0.23-0.60). Risk of death was three times higher for <5-year-old children versus those aged 10-14 years (HR: 3.03, 95% CI: 1.85-4.94) and 56% higher for those living in SEE versus SEER (HR: 1.56, 95% CI: 1.01-2.42). Regardless of geographic area and period of TKI administration, however, age seems to be a significant determinant of CML prognosis (pre-TKI period, HR0-4y: 2.71, 95% CI: 1.53-4.79; post-TKI period, HR0-4y: 3.38, 95% CI: 1.29-8.85). Noticeably, post-TKI survival in CML overall approximates that for ALL, whereas therapeutic advancements for AML remain modest. CONCLUSION Registry data show that introduction of molecular therapies coincides with revolutionised therapeutic outcomes in childhood CML entailing dramatically improved survival which is now similar to that in ALL. Given that age disparities in survival remain substantial, offering optimal therapy to entire populations is an urgent priority.

Abstract
Cultural differences in the dynamics of conflict between parents and adolescents were studied in 40 working-class Australian resident families, 20 of whom were of Anglo-Celtic descent and 20 Greek-born, and 40 Greekresident families, 20 of whom were working-class and 20 professional class. Levels and seriousness of conflict were investigated as well as three aspects of conflict dynamics: behaviour during conflict, styles of resolving conflict, and beliefs about the consequences of conflict. Mothers and adolescents were more aware than fathers of conflict and its effect on family life, they had a more differentiated set of conflict behaviours and were able to accept conflict as part of life which need not have long-term serious consequences. The results suggested that although cultural variation in response to conflict was not extensive, the immigrant Greek parents responded in ways which reflected both their Greek origin and their country of residence while their adolescents appeared to have moved towards an Anglo-Australian mode of responding. Implications for a culture conflict model, a cultural differences model and an assimilation model of intergenerational conflict in immigrant families are discussed.

Abstract
INTRODUCTION Most countries in South-Eastern Europe (SEE) have lower incidence, but higher mortality rates of malignant melanoma (MM) of the skin compared to North-Western Europe (NWE). We explored trends in MM incidence and mortality in SEE countries by sex and age and compared them with the trends in NWE. METHODS We obtained data on incident cases and deaths from MM (ICD-10 code C43) from 11 population-based cancer registries in Bosnia and Herzegovina, Bulgaria, Croatia, Cyprus, Czech Republic, Malta, Romania, Serbia, Slovakia, Slovenia and Turkey. We calculated age-specific rates for 25-49 ('young'), 50-69 ('middle aged') and 70+ years ('older') and estimated the average annual percent of change in incidence and mortality trends 2000-2010 according to age group and sex, using joinpoint regression analysis. FINDINGS The incidence rates of MM across the region were uniformly increasing. Significant increases in mortality rates were observed in middle aged men in Serbia and Bulgaria, middle aged women in Slovenia, older men in the Czech Republic, Serbia and Turkey, and older women in Slovenia and Serbia. INTERPRETATION While MM incidence rates were still increasing across SEE, mortality trends diverged and were less favourable than in NWE. Empowering cancer registration and improving the quality of incidence and mortality data will be essential for monitoring progress in MM control. In the context of prevention of melanoma, disparities in early detection appear to be widening the gap between SEE and NWE, while the provision of care to patients with advanced disease is likely to prove a challenge for regional healthcare budgets.

Abstract
AIM Childhood central nervous system (CNS) tumour registration and control programs in Southern and Eastern Europe remain thin, despite the lethal nature of the disease. Mortality/survival data were assembled to estimate the burden of malignant CNS tumours, as well as the potential role of sociodemographic survival determinants across 14 cancer registries of this region. METHODS Average age-adjusted mortality rates were calculated, whereas time trends were quantified through Poisson and Joinpoint regressions. Kaplan-Meier curves were derived for the maximum and the more recent (10 and 5 year) registration periods. Multivariate Cox regression models were used to assess demographic and disease-related determinants. RESULTS Variations in mortality (8-16 per million) and survival (5-year: 35-69%) were substantial among the participating registries; in most registries mortality trend was stable, whereas Bulgaria, having the highest starting rate, experienced decreasing annual mortality (-2.4%, p=0.001). A steep decrease in survival rates was evident before the second year of follow-up. After controlling for diagnostic subgroup, age, gender and diagnostic year, Greece seemed to present higher survival compared with the other contributing registries, although the follow-up period was short. Irrespective of country, however, rural residence was found to impose substantial adverse repercussions on survival (hazard ratio (HR): 1.2, 95% confidence interval (CI): 1.1-1.4). CONCLUSION Cross-country mortality and survival variations possibly reflect suboptimal levels of health care delivery and cancer control in some regions of Southern and Eastern Europe, notwithstanding questionable death certification patterns or follow-up procedures. Continuous childhood cancer registration and linkage with clinical data are prerequisite for the reduction of survival inequalities across Europe.

Abstract
AIM Following completion of the first 5-year nationwide childhood (0-14 years) registration in Greece, central nervous system (CNS) tumour incidence rates are compared with those of 12 registries operating in 10 Southern-Eastern European countries. METHODS All CNS tumours, as defined by the International Classification of Childhood Cancer (ICCC-3) and registered in any period between 1983 and 2014 were collected from the collaborating cancer registries. Data were evaluated using standard International Agency for Research on Cancer (IARC) criteria. Crude and age-adjusted incidence rates (AIR) by age/gender/diagnostic subgroup were calculated, whereas time trends were assessed through Poisson and Joinpoint regression models. RESULTS 6062 CNS tumours were retrieved with non-malignant CNS tumours recorded in eight registries; therefore, the analyses were performed on 5191 malignant tumours. Proportion of death certificate only cases was low and morphologic verification overall high; yet five registries presented >10% unspecified neoplasms. The male/female ratio was 1.3 and incidence decreased gradually with age, apart from Turkey and Ukraine. Overall AIR for malignant tumours was 23/10(6) children, with the highest rates noted in Croatia and Serbia. A statistically significant AIR increase was noted in Bulgaria, whereas significant decreases were noted in Belarus, Croatia, Cyprus and Serbia. Although astrocytomas were overall the most common subgroup (30%) followed by embryonal tumours (26%), the latter was the predominant subgroup in six registries. CONCLUSION Childhood cancer registration is expanding in Southern-Eastern Europe. The heterogeneity in registration practices and incidence patterns of CNS tumours necessitates further investigation aiming to provide clues in aetiology and direct investments into surveillance and early tumour detection.

Abstract
The competitive adsorption of boric acid and chromate from aqueous solutions by alumina has been investigated by spectrophotometry at pH 8, ionic strength = 0.0, 0.1 and 1.0 M NaClO4, T = 22 ± 3 °C and under normal atmospheric conditions. The experimental data show that addition of excess boric acid in the system leads to the increase of Cr(VI) concentration in solution, indicating the replacement of adsorbed chromate by boron on the alumina surface. Data evaluation results in the determination of the competition reaction constant and the formation constant of the Cr(VI) surface complexes, which are logKCr(VI)-B(III) = -3.5 ± 0.2 and logβ*Cr = 7.6 ± 0.3, respectively.

Abstract
BACKGROUND Neonatal stroke is an important cause of neurodisability in childhood and in later life. Delay in diagnosis is often inevitable due to the non-specific presentation, the lack of clinical signs, and not considering stroke early enough in the differential diagnosis. CASE We report the case of a baby who initially presented with apparent newborn "jitteriness" and abnormal movements. On the background of an unremarkable birth history and negative initial investigations, the baby subsequently developed focal seizures. The diagnosis was suspected to be neonatal stroke which was later confirmed on magnetic resonance imaging. CONCLUSION General Movements assessment is an established useful tool used in the assessment of such babies and proves helpful in evaluating whether movements are normal or pathological, in addition to prognosticating outcome. Cranial ultrasound is a commonly employed first-line investigation, however, initial normal intracranial appearances do not exclude stroke. Magnetic resonance imaging is the gold standard but may not be immediately available to all practitioners.

Abstract
For centuries, many cultures have described mythical creatures with bodies that combined human and animal features, often the result of violating taboos. This study attempted to investigate the beliefs of transplant patients about xenografting. A survey was given to 100 patients ranging in age from 17 to 74 years old, with 65 men and 35 women, including 72 whites, 18 Hispanics, 5 African Americans, and 4 Asian Americans. The subjects included liver, heart, kidney, lung, and multi-organ transplant patients. The patients were not aware of plans for xenografting at the center under study. Eighty patients agreed with xenografting in an emergency situation. Ten subjects replied, "under no circumstances." Ninety percent believed animal research has advanced medical science. In descending order, the patients preferred human (96%), monkey (44%), mechanical (43%), pig (42%), or dog (34%) organs. Twenty-four patients thought a xenograft would change their appearance, personality, or eating or sexual habits. Twenty patients believed animals have souls. The patients also documented any ethical concerns about xenografting.

Abstract
Prior to the advent of the bioartificial liver there was little hope to offer the families of comatose patients unless an organ could be found immediately, or xenografting was attempted. The elevated intracranial pressure that develops is more life-threatening than prolonged bleeding times. Over a 2-year period, nine patients were bridged to transplantation using the BAL to keep them neurologically intact prior to surgery. The goal is to maintain the ICP less than 20 mmHg in adults and between 10 and 15 mmHg in children, so that the cerebral perfusion pressure remains above 50 mmHg. The first patients, a 35-year-old woman, arrived in stage II coma. The second patient, a 10-year-old boy in stage IV coma, had decerebrate posturing and anisocoria. The third patient, an 18-year-old girl, had an ICP of 28 mmHg with decerebrate posturing and disconjugate gaze. The fourth patient, a 34-year-old male, had an ICP of > 38 mmHg. The fifth patient, a 24-year-old male, had fixed dilated pupils. The sixth patient, a 50-year-old woman, had readings to 52 mmHg. The seventh patient, a 48-year-old male, had postoperative numbness in his fingertips that remitted. The eighth patient, a 31-year-old female, had decerebrate posturing and an ICP of 64 mmHg transiently. The ninth patient, a 52-year-old woman, had decerebrate posturing with a peak ICP of 50 mmHg. All nine patients survived.

Abstract
Rat keratin K5 and vimentin complementary DNAs have been isolated, identified, and used to study keratin and vimentin expression as markers for cell differentiation. Isologous rat neoplastic epithelial cell lines used were based on a clonal benign epithelial line (A5P/B10) and a clonal anaplastic malignant derivative line (T952/F7). Stable cytoplasmic mRNA was detected for keratin but not vimentin in the benign cells. The anaplastic derivative cells expressed vimentin but showed a 1000-fold reduction in the keratin message, which nuclear run-on assays identified as being due to posttranscriptional down-regulation. An identical pattern of posttranscriptional down-regulation was found in independent malignant somatic cell hybrids of the benign and anaplastic cells. trans-acting regulatory mechanisms implicated in posttranscriptional (pretranslational) keratin down-regulation in these anaplastic malignant cells may play a role in the apparent loss of differentiation evident in tumor progression.

Abstract
According to experiential structuralism, thought abilities have six capacity spheres: experimental, propositional, quantitative, imaginal, qualitative, and metacognitive. The first five are applied to the environment. The metacognitive capacity is applied to the others, serving as the interface between reality and the cognitive system or between any of the other capacities. To test this postulate, 648 subjects aged 12 to 40 years, solved eight tasks that were addressed, in pairs, to the first four capacity spheres. One of the tasks in each pair tapped the first and the other the third formal level of the sphere. Having solved the tasks, the subjects were required to rate each pair of tasks in terms of similarity of operations, difficulty, and success of solution. Factor analysis of difficulty and success evaluation scores revealed the same capacity-specific factors as the analysis of performance scores. Factor analysis of similarity scores differentiated between same- and different-sphere pairs. Analysis of variance showed that difficulty and success evaluation scores preserved performance differences between the first and the third formal tasks. Cognitive level, age, socioeconomic status, and sex were related to the metacognitive measures in ways similar to their relations to performance measures. These findings were integrated into a model aimed at capturing real-time metacognitive functioning.

Abstract
Twenty (44%) of 45 patients with cutaneous pellagra had diarrhoea. Inflammation was seen on sigmoidoscopy in 42 and was severe in 5 (11%), moderate in 4 (9%) and mild in 33 (73%). Six patients (13%) had perianal excoriation. Rectal biopsies taken in all cases showed extensive ulceration in 1 case, moderate to severe inflammation in 16 (36%) and mild inflammation in 18 (40%). Minimal oedema of the lamina propria was seen in 11 (24%) patients. At 5 to 7 days after starting vitamin treatment in nine cases histological changes had returned to normal in 4, improved in 3 and had not changed in 2. Diarrhoea stopped within a week in all cases.

Abstract
A 2 1/2-year-old girl recently arrived from eastern Nigeria presented with a soft tissue swelling of the infraclavicular region. Subsequent investigation revealed a cavity in the left lung associated with a small pleural effusion and leucocytosis with pronounced eosinophilia. Clinical and serological findings were compatible with the diagnosis of paragonimiasis. After a course of Bitin-S the chest x-ray returned to normal, the soft tissue changes disappeared, and the eosinophil count fell.

Abstract
Vitamin A palmitate was incorporated into a laboratory chow (150,000 IU/kg diet) and fed ad libitum to C3H/HeJ female mice inoculated with 1 times 10-6 C3HBA tumor cells, beginning the day of inoculation. Control female mice of the same strain similarly inoculated were fed the laboratory chow alone. Vitamin A did not affect rate for the first 19 days, after which growth rates were independent of treatment. Vitamin A-treated mice survived for significantly longer times than did control mice.
