RESUMO

BACKGROUND/OBJECTIVES: When studying the effect of weight change between two time points on a health outcome using observational data, two main problems arise initially (i) 'when is time zero?' and (ii) 'which confounders should we account for?' From the baseline date or the 1st follow-up (when the weight change can be measured)? Different methods have been previously used in the literature that carry different sources of bias and hence produce different results. METHODS: We utilised the target trial emulation framework and considered weight change as a hypothetical intervention. First, we used a simplified example from a hypothetical randomised trial where no modelling is required. Then we simulated data from an observational study where modelling is needed. We demonstrate the problems of each of these methods and suggest a strategy. INTERVENTIONS: weight loss/gain vs maintenance. RESULTS: The recommended method defines time-zero at enrolment, but adjustment for confounders (or exclusion of individuals based on levels of confounders) should be performed both at enrolment and the 1st follow-up. CONCLUSIONS: The implementation of our suggested method [adjusting for (or excluding based on) confounders measured both at baseline and the 1st follow-up] can help researchers attenuate bias by avoiding some common pitfalls. Other methods that have been widely used in the past to estimate the effect of weight change on a health outcome are more biased. However, two issues remain (i) the exposure is not well-defined as there are different ways of changing weight (however we tried to reduce this problem by excluding individuals who develop a chronic disease); and (ii) immortal time bias, which may be small if the time to first follow up is short.

RESUMO

OBJECTIVES: Obesity is a modifiable risk factor for coronavirus disease 2019 (COVID-19)-related mortality. We estimated excess mortality in obesity, both 'direct', through infection, and 'indirect', through changes in health care, and also due to potential increasing obesity during lockdown. STUDY DESIGN: The study design of this study is a retrospective cohort study and causal inference methods. METHODS: In population-based electronic health records for 1,958,638 individuals in England, we estimated 1-year mortality risk ('direct' and 'indirect' effects) for obese individuals, incorporating (i) pre-COVID-19 risk by age, sex and comorbidities, (ii) population infection rate and (iii) relative impact on mortality (relative risk [RR]: 1.2, 1.5, 2.0 and 3.0). Using causal inference models, we estimated impact of change in body mass index (BMI) and physical activity during 3-month lockdown on 1-year incidence for high-risk conditions (cardiovascular diseases, diabetes, chronic obstructive pulmonary disease and chronic kidney disease), accounting for confounders. RESULTS: For severely obese individuals (3.5% at baseline), at 10% population infection rate, we estimated direct impact of 240 and 479 excess deaths in England at RR 1.5 and 2.0, respectively, and indirect effect of 383-767 excess deaths, assuming 40% and 80% will be affected at RR = 1.2. Owing to BMI change during the lockdown, we estimated that 97,755 (5.4%: normal weight to overweight, 5.0%: overweight to obese and 1.3%: obese to severely obese) to 434,104 individuals (15%: normal weight to overweight, 15%: overweight to obese and 6%: obese to severely obese) would be at higher risk for COVID-19 over one year. CONCLUSIONS: Prevention of obesity and promotion of physical activity are at least as important as physical isolation of severely obese individuals during the pandemic.

RESUMO

BACKGROUND: Intakes of specific fatty acids have been postulated to impact breast cancer risk but epidemiological data based on dietary questionnaires remain conflicting. MATERIALS AND METHODS: We assessed the association between plasma phospholipid fatty acids and breast cancer risk in a case-control study nested within the European Prospective Investigation into Cancer and Nutrition study. Sixty fatty acids were measured by gas chromatography in pre-diagnostic plasma phospholipids from 2982 incident breast cancer cases matched to 2982 controls. Conditional logistic regression models were used to estimate relative risk of breast cancer by fatty acid level. The false discovery rate (q values) was computed to control for multiple comparisons. Subgroup analyses were carried out by estrogen receptor (ER) and progesterone receptor expression in the tumours. RESULTS: A high level of palmitoleic acid [odds ratio (OR) for the highest quartile compared with the lowest OR (Q4-Q1) 1.37; 95% confidence interval (CI), 1.14-1.64; P for trend = 0.0001, q value = 0.004] as well as a high desaturation index (DI16) (16:1n-7/16:0) [OR (Q4-Q1), 1.28; 95% C, 1.07-1.54; P for trend = 0.002, q value = 0.037], as biomarkers of de novo lipogenesis, were significantly associated with increased risk of breast cancer. Levels of industrial trans-fatty acids were positively associated with ER-negative tumours [OR for the highest tertile compared with the lowest (T3-T1)=2.01; 95% CI, 1.03-3.90; P for trend = 0.047], whereas no association was found for ER-positive tumours (P-heterogeneity =0.01). No significant association was found between n-3 polyunsaturated fatty acids and breast cancer risk, overall or by hormonal receptor. CONCLUSION: These findings suggest that increased de novo lipogenesis, acting through increased synthesis of palmitoleic acid, could be a relevant metabolic pathway for breast tumourigenesis. Dietary trans-fatty acids derived from industrial processes may specifically increase ER-negative breast cancer risk.

RESUMO

BACKGROUND: Hip fractures are associated with diminished quality of life and survival especially amongst the elderly. OBJECTIVE: All-cause mortality after hip fracture was investigated to assess its magnitude. METHODS: A total of 122 808 participants from eight cohorts in Europe and the USA were followed up for a mean of 12.6 years, accumulating 4273 incident hip fractures and 27 999 deaths. Incident hip fractures were assessed through telephone interviews/questionnaires or national inpatient/fracture registries, and causes of death were verified with death certificates. Cox proportional hazards models and the time-dependent variable methodology were used to assess the association between hip fracture and mortality and its magnitude at different time intervals after the injury in each cohort. We obtained the effect estimates through a random-effects meta-analysis. RESULTS: Hip fracture was positively associated with increased all-cause mortality; the hazard ratio (HR) in the fully adjusted model was 2.12, 95% confidence interval (CI) 1.76-2.57, after adjusting for potential confounders. This association was stronger amongst men [HR: 2.39, 95% CI: 1.72-3.31] than amongst women [HR: 1.92, 95% CI: 1.54-2.39], although this difference was not significant. Mortality was higher during the first year after the hip fracture [HR: 2.78, 95% CI: 2.12-3.64], but it remained elevated without major fluctuations after longer time since hip fracture [HR (95% CI): 1.89 (1.50-2.37) after 1-4 years; 2.15 (1.81-2.55) after 4-8 years; 1.79 (1.57-2.05) after 8 or more years]. CONCLUSION: In this large population-based sample of older persons across eight cohorts, hip fracture was associated with excess short- and long-term all-cause mortality in both sexes.

RESUMO

BACKGROUND: Particulate matter (PM) air pollution is a human lung carcinogen; however, the components responsible have not been identified. We assessed the associations between PM components and lung cancer incidence. METHODS: We used data from 14 cohort studies in eight European countries. We geocoded baseline addresses and assessed air pollution with land-use regression models for eight elements (Cu, Fe, K, Ni, S, Si, V and Zn) in size fractions of PM2.5 and PM10. We used Cox regression models with adjustment for potential confounders for cohort-specific analyses and random effect models for meta-analysis. RESULTS: The 245,782 cohort members contributed 3,229,220 person-years at risk. During follow-up (mean, 13.1 years), 1878 incident cases of lung cancer were diagnosed. In the meta-analyses, elevated hazard ratios (HRs) for lung cancer were associated with all elements except V; none was statistically significant. In analyses restricted to participants who did not change residence during follow-up, statistically significant associations were found for PM2.5 Cu (HR, 1.25; 95% CI, 1.01-1.53 per 5 ng/m(3)), PM10 Zn (1.28; 1.02-1.59 per 20 ng/m(3)), PM10 S (1.58; 1.03-2.44 per 200 ng/m(3)), PM10 Ni (1.59; 1.12-2.26 per 2 ng/m(3)) and PM10 K (1.17; 1.02-1.33 per 100 ng/m(3)). In two-pollutant models, associations between PM10 and PM2.5 and lung cancer were largely explained by PM2.5 S. CONCLUSIONS: This study indicates that the association between PM in air pollution and lung cancer can be attributed to various PM components and sources. PM containing S and Ni might be particularly important.

RESUMO

BACKGROUND AND AIMS: High glycemic load (GL) has been associated with increased coronary heart disease (CHD) risk. We evaluated whether preference of low-GL foods conveys incremental benefits with respect to CHD, especially to people adhering to the traditional Mediterranean diet (MD). METHODS AND RESULTS: We analyzed data from the Greek European Prospective Investigation into Cancer and Nutrition, including 20,275 participants free of cardiovascular diseases, cancer, or diabetes at baseline and without incident diabetes. Subjects completed a validated, semi-quantitative food frequency questionnaire at enrollment. We calculated a 10-point MD adherence score and the dietary GL, and estimated hazard ratios (HRs) for CHD incidence and mortality through Cox proportional hazard regression. After a median follow-up of 10.4 years, 417 participants developed CHD, and 162 died from the disease. A significant positive association of GL with CHD incidence emerged (HR for the highest versus the lowest tertile = 1.41, 95% confidence interval, CI: 1.05-1.90). HRs for CHD mortality exceeded unity but were not statistically significant. The association with GL was stronger among subjects with higher body mass index. High adherence to MD with low/moderate GL was associated with lower risk of CHD incidence (HR = 0.61, CI: 0.39-0.95) and mortality (HR = 0.47, 95% CI: 0.23-96). CONCLUSION: High dietary GL increases the risk of CHD. Compared to a high GL diet with suboptimal adherence to the traditional Mediterranean pattern, a low/moderate GL diet that also conforms to the traditional MD principles could lead to a 40% reduced risk for CHD, and over 50% reduced risk for death from CHD.

RESUMO

We report a case of pregnancy in a 34-year-old woman with uncorrected tetralogy of Fallot (TOF). There are more risks in patients without surgical correction. In our case, haemoglobin and haematocrit were higher, oxygen saturation was lower, and right ventricular enlargement was observed. Pregnancy was resolved successfully by caesarean section. Improvement of fetomaternal outcome may be related to corrective procedures before conception to achieve better functional heart capacity. Delicate multidisciplinary medical management is essential for these limited cases to achieve optimal prognosis.

RESUMO

BACKGROUND/OBJECTIVES: Heavy alcohol drinking is a risk factor of colorectal cancer (CRC), but little is known on the effect of polymorphisms in the alcohol-metabolizing enzymes, alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH) on the alcohol-related risk of CRC in Caucasian populations. SUBJECTS/METHODS: A nested case-control study (1269 cases matched to 2107 controls by sex, age, study centre and date of blood collection) was conducted within the European Prospective Investigation into Cancer and Nutrition (EPIC) to evaluate the impact of rs1229984 (ADH1B), rs1573496 (ADH7) and rs441 (ALDH2) polymorphisms on CRC risk. Using the wild-type variant of each polymorphism as reference category, CRC risk estimates were calculated using conditional logistic regression, with adjustment for matching factors. RESULTS: Individuals carrying one copy of the rs1229984(A) (ADH1B) allele (fast metabolizers) showed an average daily alcohol intake of 4.3 g per day lower than subjects with two copies of the rs1229984(G) allele (slow metabolizers) (P(diff)<0.01). None of the polymorphisms was associated with risk of CRC or cancers of the colon or rectum. Heavy alcohol intake was more strongly associated with CRC risk among carriers of the rs1573496(C) allele, with odds ratio equal to 2.13 (95% confidence interval: 1.26-3.59) compared with wild-type subjects with low alcohol consumption (P(interaction)=0.07). CONCLUSIONS: The rs1229984(A) (ADH1B) allele was associated with a reduction in alcohol consumption. The rs1229984 (ADH1B), rs1573496 (ADH7) and rs441 (ALDH2) polymorphisms were not associated with CRC risk overall in Western-European populations. However, the relationship between alcohol and CRC risk might be modulated by the rs1573496 (ADH7) polymorphism.

RESUMO

OBJECTIVE: To determine the extent to which the risk for incident coronary heart disease (CHD) increases in relation to a genetic risk score (GRS) that additively integrates the influence of high-risk alleles in nine documented single nucleotide polymorphisms (SNPs) for CHD, and to examine whether this GRS also predicts incident stroke. METHODS: Genotypes at nine CHD-relevant SNPs were determined in 494 cases of incident CHD, 320 cases of incident stroke and 1345 unaffected controls drawn from the population-based Greek component of the European Prospective Investigation into Cancer and nutrition (EPIC) cohort. An additive GRS was calculated for each study participant by adding one unit for the presence of each high-risk allele multiplied by the estimated effect size of that allele in the discovery samples. Statistical analysis was performed using logistic regression. RESULTS: The GRS was significantly associated with the incidence of CHD where the odds of CHD incidence in the highest quintile of the GRS were 1.74 times higher (95% confidence interval [CI]=1.25-2.43, p for trend=0.0004), compared to the lowest quintile. With respect to stroke, a weaker and non-significant positive association with GRS was apparent as the odds of stroke incidence in the highest quintile of the GRS were 1.36 times higher (95% CI=0.90-2.06, p for trend=0.188), compared to the lowest quintile. CONCLUSION: A GRS relying on nine documented "CHD-specific" SNPs is significantly predictive of CHD but it was not found to be statistically significantly associated with incident stroke.

RESUMO

OBJECTIVE: The aim of this study was to examine the association of body mass index (BMI) and weight gain with eating at restaurants and similar establishments or eating at work among 10 European countries of the European Prospective Investigation into Cancer and Nutrition (EPIC) study. SUBJECTS: This study included a representative sample of 24,310 randomly selected EPIC participants. METHODS: Single 24-h dietary recalls with information on the place of consumption were collected using standardized procedures between 1995 and 2000. Eating at restaurants was defined to include all eating and drinking occasions at restaurants, cafeterias, bars and fast food outlets. Eating at work included all eating and drinking occasions at the workplace. Associations between eating at restaurants or eating at work and BMI or annual weight changes were assessed using sex-specific linear mixed-effects models, controlling for potential confounders. RESULTS: In southern Europe energy intake at restaurants was higher than intake at work, whereas in northern Europe eating at work appeared to contribute more to the mean daily intake than eating at restaurants. Cross-sectionally, eating at restaurants was found to be positively associated with BMI only among men (ß=+0.24, P=0.003). Essentially no association was found between BMI and eating at work among both genders. In a prospective analysis among men, eating at restaurants was found to be positively, albeit nonsignificantly, associated with weight gain (ß=+0.05, P=0.368). No association was detected between energy intake at restaurants and weight changes, controlling for total energy intake. CONCLUSION: Among men, eating at restaurants and similar establishments was associated with higher BMI and possibly weight gain.

RESUMO

Minimal deviation cervical adenocarcinoma, otherwise known as adenoma malignum, is a rare and particularly well differentiated type of cervical adenocarcinoma, and is often misdiagnosed because of its benign-looking histological features. Adenoma malignum represents only 1-3% of all cervical adenocarcinomas. The Papanicolaou smear as well as punch biopsies can fail in the detection of adenoma malignum. We present the case of a 55-year-old woman diagnosed as having microinvasive minimal deviation of the adenocarcinoma cervix, after conisation for a high-grade cervical squamous intraepithelial lesion. The patient was referred for an abnormal pap smear to our colposcopy clinic where the punch biopsies performed failed to diagnose the disease. The consequent cone biopsy because of CIN3, provided us with a definite diagnosis of adenoma malignum. Subsequently, the patient underwent a radical hysterectomy and pelvic lymph node dissection. The histologic examination was normal. Coexistence of a squamous intraepithelial lesion with adenoma malignum is extremely uncommon.

RESUMO

Primary malignant vaginal melanoma is a rare vaginal tumour accompanied by an extremely high risk of local recurrence, distant metastasis and a small survival rate. Due to the fact that vaginal melanoma is quite uncommon there is lack of powerful prospective studies in the literature, thus the treatment choice remains controversial. An 85-year-old woman with a primary malignant vaginal melanoma located on the left lateral aspect of the distal vagina, with the greatest diameter almost 5 cm, was referred to our clinic. There was not any sign of local or distant metastasis identified. According to the most recently published data in the international literature, we decided along with the patient to perform conservative dissection of the tumor with free surgical margins as the appropriate mode of therapy. Radiotherapy, chemotherapy or radical extirpation cannot increase the survival time, even if there is a local or distant spread of melanoma.

RESUMO

Pure Sertoli cell tumor (SCT) is a rare sex cord tumor and a subtype of Sertoli-Leydig cell tumors according to the WHO Classification. They lack a Leydig cell component and do not contain the immature neoplastic stroma found in the neoplasms of the Sertoli-Leydig cell category. The age of the patients ranges between two and 79 years. Sertoli cell tumors occur in women of reproductive age but a few can also occur in children. The most common clinical presentation when occurring in children is isosexual pseudoprecocity. Women of reproductive age and postmenopausal women frequently present with abdominal pain, swelling and menstrual abnormalities. Occasionally SCTs occur in patients who have Peutz-Jeghers syndrome. The tumors are hormone functional in 40-60% of cases. They are often estrogenic, occasionally also androgenic or rarely both. Grossly they are usually yellow to brownish, solid or with several cystic areas. Microscopically they show always almost a tubular growth pattern, but they may also have other growth patterns which can be extensive, making the correct diagnosis difficult. These histologic patterns may result in SCTs mimicking other ovarian tumors. The immunohistochemical panel which usually includes EMA, inhibin, chromogranine, CD99 and calretinin is often helpful in establishing the diagnosis. Most SCTs are Stage I, unilateral, cytologically bland, and clinically benign, but occasional examples are high stage. About 11% of Stage I tumors have worrisome histologic features that may portend an adverse outcome.

RESUMO

PURPOSE: This phase II pilot study was conducted to evaluate the results of a three-modality approach (which included post-chemoradiotherapy surgery) in advanced-stage cervical carcinomas. PATIENTS AND METHODS: Thirty-six patients underwent either surgery or were put on follow-up after having received radical cervical radiotherapy (RT) combined with radiosensitizing chemoimmunotherapy with irinotecan (CPT-11), interferon (IFN) A2b, and amifostine. The last selection (surgery or follow-up) was based on clinical evaluation (downstaged or not). Feasibility, morbidity, surgical outcome and survival were evaluated. RESULTS: Twenty-six patients had stage IIb and 10 IIIb disease at diagnosis. Sixteen (44%) were clinically downstaged, thus becoming eligible for surgery. Twelve (33%) were operated and the others were put on follow-up. There was no significant increase in treatment-related morbidity of the group of patients receiving three-modality therapy, since only one intraoperative complication had occurred. In 58% of the operated patients, chemoradiotherapy-resistant tumor was found on pathology of the cervical specimens, while 29% of them had lymph nodes infiltrated by the tumor. After a median follow-up of 42.5 months, overall survival (OS) of operated vs. non-operated patients (88 vs. 56%, respectively) show only a trend toward significance (p=0.10). The overall recurrence/metastasis rate was 36.1% and the disease-free survival (DFS) 56% for operated vs. 76% for non-operated patients, respectively (p=0.63). CONCLUSION: These results indicate that post-chemoradiotherapy surgery is justified because of the high rate of residual disease found. Morbidity can be effectively limited with proper patient selection. A considerable survival benefit is expected, although this remains to be confirmed with phase III studies.

RESUMO

BACKGROUND: Primary peritoneal papillary serous carcinoma (PPPSC) is an uncommon primary malignancy of the peritoneum. The aim of our study is to present the characteristics of such a rare entity through our case series. METHOD: This is a retrospective study of nine cases of PPPSC who were treated between January 2002 and April 2007 in METAXA Memorial Cancer Hospital, Piraeus, Greece. Medical files and histopathological diagnosis of each patient were retrospectively studied. RESULTS: The median age of the patients was 63 years ranging from 44 up to 74 years. Clinically PPPSC presented with general abdominal discomfort in all of the patients. Three out of nine patients presented with constipation, 5/9 with distention, and 7/9 with ascites. All of the patients referred loss of appetite with weight gaining due to ascites. All the patients had pathological values of CA125 (over 35 U/ml) ranging from 125 up to 1,255 U/ml with median value 565 U/ml. Optimal debulking was possible in 3/9 of patients who were consequently treated with standard taxol-platin chemotherapy. Complete response was achieved in one woman. The median disease-free survival was 7 months and the median overall survival rate was 2.5 years. CONCLUSION: PPPSC mimics ovarian papillary serous carcinoma regarding the clinical and laboratory characteristics but it has worse prognosis.

RESUMO

PURPOSE: The objective of this study was to investigate the prognostic significance of glandular dyskaryosis/AGUS, reported in Papanicolaou (Pap) smears. MATERIALS AND METHODS: During a 4-year period 26,408 smears were assessed at the Department of Cytology of our hospital. Thirty (0.11%) smears were reported as having glandular dyskaryosis. The studied material was taken by colposcopy, fractional curettage and/or cone biopsy. RESULTS: The final diagnosis included 2 cases of invasive cervical carcinoma (1 squamous cell and 1 adenocarcinoma), 1 case with ovarian cancer, 8 cases with high grade squamous intraepithelial lesion (HGSIL) and 10 cases with other nonmalignant pathology (polyps, hyperplasia) of endometrial origin. These findings reflect a 36.7% positive predictive value for significant squamous and glandular pathology. CONCLUSION: Patients with glandular dyskaryosis require further evaluation because it may hide serious pathology from all internal genital organs. Colposcopy in combination with fractional curettage and/or cone biopsy are proposed as the appropriate diagnostic tools in women with such cytological abnormality.

RESUMO

We present the case of a 53-year-old lady with incidental diagnosis of struma ovarii 10 years after total thyroidectomy due to papillary thyroid carcinoma. The disease was diagnosed owing to high levels of serum thyroglobulin. The patient underwent exploratory laparotomy with total hysterectomy and bilateral salpingo-oophorectomy. Close follow-up was proposed and her prognosis is excellent.

RESUMO

The triad of ascites, hydrothorax in association with a benign ovarian tumor is defined as Meig's syndrome. It is a rare clinical entity. A case of a 62 year-old woman whith dyspnoe, abdominal discomfort and ascites is presented. Clinical and ultrasonographic findings revealed extended palpable pelvic mass originating from the ovaries and ascites as well as hydrothorax of the left lung by chest radiography. The treatment method was surgical intervention. Cytomorphologic studies were positive for malignacy and adenocarcinoma cells were confirmed. The pathogenesis of the pleural and ascites fluids and the importance of CA-125 are discussed (Fig. 2, Ref. 21).

RESUMO

BACKGROUND: The development of genuine vaginal carcinoma onto a completely prolapsed uterus is a very rare condition to deal with. CASE: We report here the clinical characteristics of a patient with vaginal carcinoma associated with a third-degree prolapsed uterus. The 80-year-old patient was admitted with a completely prolapsed uterus. The cervix was clinically normal but on the nearby prolapsed vaginal wall a large exophytical hard lesion had been developed. Biopsy of the lesion revealed squamous carcinoma. TREATMENT: The treatment performed was radical vaginal hysterectomy and excision of the upper two-thirds of the vagina without pelvic lymphadenectomy, followed by external beam irradiation. The patient is alive, with no signs of the disease 3.5 years after surgery. CONCLUSION: Surgical and radiotherapeutic treatments can be effectively combined in patients with vaginal carcinoma and complete genital prolapse, in order to improve survival benefits and reduce morbidity.
