Quality of life and psychological distress in locally advanced cervical cancer patients administered pre-operative chemoradiotherapy

ObjectiveThe aim of the study was to analyze the Quality of life (QoL) scores in a single institution series of locally advanced cervical cancer patients (LACC) administered preoperative chemoradiation, compared to early stage disease (ECC) patients undergoing radical surgery.MethodsThe following criteria were required in order to enroll patients: age between 18 and 65years at initial diagnosis, at least 12months from the end of treatment, no evidence of recurrence/second malignancy. The SF-36 questionnaire on general health, and the HADS questionnaire on mental distress were utilized.Results93 subjects were available for the analysis. At time of analysis, median follow-up was 30months (range 12–120). LACC patients showed QoL scores comparable to ECC patients with the exception of physical functioning (mean ± SD = 69.0 ± 13.1 versus mean ± SD = 85.4 ± 16.2, p value = 0.0007). In the group of LACC patients, the presence of co-morbidities was significantly associated with the impairment of almost all subscales of QoL. A low education level and the status of unemployment were documented to negatively impact on the vast majority of SF-36 subscale scores. In the multivariate analysis, the presence of co-morbidities, low educational level, age> 50years, and unemployment maintained their independent negative association with poor QoL scores. The percentage of cases with high levels HADS-anxiety was higher in LACC than ECC patients (27.6% versus 8.6%, p value = 0.034).ConclusionsLACC patients administered preoperative chemoradiation showed QoL scores comparable to EEC patients, and a higher proportion of anxiety disorders; low educational level and unemployment status were mainly associated with poor QoL scores.     

Age at sexual initiation and number of sexual partners in the female Spanish population Results from the AFRODITA survey

Objectives

The AFRODITA study was designed to describe patterns relating to the number of lifetime sexual partners (SP) and age at first sexual intercourse (AFSI) by geographic region in a representative sample of Spanish women.

Study design

A representative sample of the female Spanish population was obtained using the Access Panel Technique. Postal questionnaires were sent to 11,086 women aged 18–70 years. Data were collected on AFSI, number of sexual partners, contraceptive methods, cervical cancer screening and socio-demographic characteristics.

Results

The average AFSI was 20.9 years. AFSI below the age of 19 years was reported by 30.8% of the women. Among sexually active women, 70.6% reported being monogamous and 6.4% reported ≥5 lifetime sexual partners. Younger age at interview was strongly related to earlier AFSI and to higher number of lifetime sexual partners. Women younger than 25 were 39 times more likely to have an AFSI before age 18 than women over age 55. The percentage of women aged less than 25 reporting two or more sexual partners was four times higher than that of women 56 and older. In the multivariate analysis, having two or more sexual partners was independently associated with young age, early AFSI, having ever used oral contraceptives, living in an urban area, having had a screening Pap test in the last 3 years, having a sexually transmitted infection and nuliparity.

Conclusions

This study confirms important changes in the sexual behaviour of Spanish women. Younger cohorts show a younger age at sexual initiation and higher number of sexual partners. These are key factors that may induce changes in the human papillomavirus (HPV) prevalence and the cervical cancer incidence in Spain.     

Natural Volcanic Material as a Sustainable Photocatalytic Material for Pollutant Degradation under Solar Irradiation

Recently, photocatalysis has been demonstrated as a solid approach for efficient wastewater cleaning. Using natural materials as photocatalysts means a promising solution to develop green catalysts for environmental purposes. This work aimed to study the suitability of a natural volcanic material (La Gomera, Canary Islands, Spain) as a photocatalytic material for the degradation of pollutants in wastewater with solar energy. After analysing the properties of the natural material (BET surface 0.188 m²/g and band-gap of 3 eV), the photocatalytic activity was evaluated at laboratory and pilot plant scale for the degradation of methylene blue (MB) in water (50 mg L⁻¹), at 20 °C, during a period of 4 h, under UV/Vis light and solar irradiation. Photolytic and adsorption studies were developed to distinguish the photocatalytic contribution to the wastewater decontamination process by photocatalysis. Our results enable us to determine the viability of black sand as a photocatalytic material activated by solar irradiation (photodegradation of MB up to 100% by using solar energy), developing a natural and green photocatalytic system with significantly high potential for application in a sustainable wastewater cleaning process.     

Reactive vaccination as control strategy for an outbreak of invasive meningococcal disease caused by Neisseria meningitidis C:P1.5-1,10-8:F3-6:ST-11(cc11), Bergamo province,Italy, December 2019 to January 2020

In Italy, serogroup C meningococci of the clonal complex cc11 (MenC/cc11) have caused several outbreaks of invasive meningococcal disease (IMD) during the past 20 years. Between December 2019 and January 2020, an outbreak of six cases of IMD infected with MenC/cc11 was identified in a limited area in the northern part of Italy. All cases presented a severe clinical picture, and two of them were fatal. This report is focused on the microbiological and molecular analysis of meningococcal isolates with the aim to reconstruct the chain of transmission. It further presents the vaccination strategy adopted to control the outbreak. The phylogenetic evaluation demonstrated the close genetic proximity between the strain involved in this outbreak and a strain responsible for a larger epidemic that had occurred in 2015 and 2016 in the Tuscany Region. The rapid identification and characterisation of IMD cases and an extensive vaccination campaign contributed to the successful control of this outbreak caused by a hyperinvasive meningococcal strain.     

Randomised Clinical Trial to Analyse the Efficacy of Eggshell Membrane to Improve Joint Functionality in Knee Osteoarthritis

Osteoarthritis is a source of chronic pain and disability. Dietary supplements have been shown to be a more secure option than NSAIDS. Particularly, the eggshell membrane has demonstrated efficacy in relieving joint pain and stiffness. A clinical trial was designed in which three groups were assigned to two different doses of this supplement and compared to a placebo control group. The primary outcome variable was knee pain, which was assessed using a visual analogue scale. Secondary outcome variables were knee functional ability, quadriceps muscle strength (assessed by isometric and isokinetic trials), and quality of sleep. All groups showed a significant decrease in pain perception, although maximum values were obtained in the high-dose group. Isokinetic and isometric trials showed a significant increase in strength in the high-dose group. Eggshell membrane showed the potential to reduce pain and stiffness symptomatology. Here, for the first time, two quantitative variables (mobility and strength of knee joint) were used to accurately evaluate changes in the quality of life of subjects affected by knee joint pain. The results of this study indicate a dose-dependent response, which should be taken into account for later use in therapeutics to establish the correct dosage.     

Gut Microbiota Markers and Dietary Habits Associated with Extreme Longevity in Healthy Sardinian Centenarians

This study was aimed at characterizing the gut microbiota (GM) and its functional profile in two groups of Sardinian subjects with a long healthy life expectancy, overall named Long-Lived Subjects (LLS) [17 centenarians (CENT) and 29 nonagenarians (NON)] by comparing them to 46 healthy younger controls (CTLs). In addition, the contribution of genetics and environmental factors to the GM phenotype was assessed by comparing a subgroup of seven centenarian parents (CPAR) with a paired cohort of centenarians’ offspring (COFF). The analysis was performed through Next Generation Sequencing (NGS) of the V3 and V4 hypervariable region of the 16S rRNA gene on the MiSeq Illumina platform. The Verrucomicrobia phylum was identified as the main biomarker in CENT, together with its members Verrucomicrobiaceae, Akkermansia and Akkermansia muciniphila. In NON, the strongest associations concern Actinobacteria phylum, Bifidobacteriaceae and Bifidobacterium, while in CTLs were related to the Bacteroidetes phylum, Bacteroidaceae, Bacteroides and Bacteroides spp. Intestinal microbiota of CPAR and COFF did not differ significantly from each other. Significant correlations between bacterial taxa and clinical and lifestyle data, especially with Mediterranean diet adherence, were observed. We observed a harmonically balanced intestinal community structure in which the increase in taxa associated with intestinal health would limit and counteract the action of potentially pathogenic bacterial species in centenarians. The GM of long-lived individuals showed an intrinsic ability to adapt to changing environmental conditions, as confirmed by functional analysis. The GM analysis of centenarians’ offspring suggest that genetics and environmental factors act synergistically as a multifactorial cause in the modulation of GM towards a phenotype similar to that of centenarians, although these findings need to be confirmed by larger study cohorts and by prospective studies.     

Very Low Alcohol Consumption Is Associated with Lower Prevalence of Cirrhosis and Hepatocellular Carcinoma in Patients with Non-Alcoholic Fatty Liver Disease

The role of moderate alcohol consumption in the evolution of NAFLD is still debated. The aim of this study is to evaluate the impact of current and lifelong alcohol consumption in patients with NAFLD. From 2015 to 2020, we enrolled 276 consecutive patients fulfilling criteria of NAFLD (alcohol consumption up to 140 g/week for women and 210 g/week for men). According to their current alcohol intake per week, patients were divided in: abstainers, very low consumers (C1: <70 g/week) and moderate consumers (C2). We created a new tool, called LACU (Lifetime Alcohol Consuming Unit) to estimate the alcohol exposure across lifetime: 1 LACU was defined as 7 alcohol units per week for 1 drinking year. Patients were divided into lifelong abstainers and consumers and the latter furtherly divided into quartiles: Q1-Q4. Stratification according to alcohol intake, both current and cumulative as estimated by LACU, showed that very low consumers (C1 and Q1-Q3) displayed lower frequency of cirrhosis and hepatocellular carcinoma compared to abstainers and moderate consumers (C2 and Q4). We can speculate that up to one glass of wine daily in the context of a Mediterranean diet may be a long-term useful approach in selected NAFLD patients.
