RESUMO

BACKGROUND: The aims of the study were to determine, in the urine and oral samples of young adults, the genotype-specific prevalence of Human Papilloma Virus (HPV) infection, the HPV DNA type-specific prevalence in unvaccinated and vaccinated individuals, and the determinants of HPV infection. METHODS: Selected participants were asked to fill in a self-administered questionnaire and to self-collect urine and saliva samples. RESULTS: Among the 1002 participants, 81 (8.1%) resulted positive for HPV DNA. The most common low-risk genotype was HPV 42 (2.2%), followed by HPV 43 (0.8%), and 40 (0.5%). The HPV 51 was the most common high-risk genotype (1.5%) followed by HPV 66 (1%) and HPV 68 (1%), and no participants were infected with HPV genotypes 18, 33, 45. Females, those who have had one or more occasional sexual partner, those who never/rarely/sometimes used condoms during their sexual activity, those with a previous diagnosis of sexually transmitted infection, and those who were not vaccinated were more likely to be tested positive for HPV infection. CONCLUSIONS: The low prevalence of genital HPV infections has provided evidence of the effectiveness of HPV vaccination both in vaccinated and not yet vaccinated subjects through herd immunity and indicated its decisive role in the changing epidemiology of circulating HPV genotypes in the population.

RESUMO

The COVID-19 pandemic period was marked by the absence or reduced circulation of some infectious diseases. Legionellosis may have been affected by the prevention measures adopted to counter COVID-19. Legionellosis is a form of pneumonia interstitial that is normally transmitted via aerosol-containing bacteria (genus Legionella), that could be present in contaminated water sources and is often associated with travel and with staying in hotels. In this work, the data of the environmental surveys carried out by ARPA Campania in accommodation facilities since 2019 were analyzed for a better understanding of the dispersion patterns of L. pneumophila associated with the environment and to evaluate the variation of the data during the pandemic period. The aim was to provide a better understanding of Legionella at different geographic scales and to define a predictive epidemiological method. Results: In 2019, the Legionella genus contaminated 37.7% of all tourist facilities evaluated. In 2020, the Legionella genus contaminated 44.4% of all tourist facilities evaluated. In 2021, the Legionella genus contaminated 54.2% of all tourist facilities evaluated. Conclusions: Legionella pneumophila was the most prevalent species in our community, serogroup 1 was the most frequently isolated and the most implicated risk factor of contamination was the temperature of water in circulation.

RESUMO

This review aims to evaluate the effects of probiotic supplementation on performance and performance-related conditions in athletes by evaluating randomized controlled studies from the MEDLINE (Pubmed), Web of Science, Scopus, and SPORTDiscus (EBSCO) databases. From a total of 2304 relevant articles, 13 studies fulfilled the inclusion criteria. Seven studies concern endurance athletes, one to rugby players, three refer to non-specified athletes, one to badminton players, and one involves baseball players. The evidence suggests that the integration of athletes' diets with some bacterial strains and also the consumption of multi-strain compounds may lead to an improvement in performance and can positively affect performance-related aspects such as fatigue, muscle pain, body composition, and cardiorespiratory fitness. However, the type of supplementation and sport is very variable among the studies examined. Therefore, to obtain more solid evidence, further controlled and comparable studies are needed to expand the research regarding the possible repercussions of probiotics use on athletes' performance.

RESUMO

Background: The association between Type 1 Diabetes Mellitus (T1DM) and obesity (Ob) is no longer unexpected due to unhealthy lifestyle mostly in adolescents. We compared clinical-biochemical characteristics, adherence to the Mediterranean Diet (MD), lifestyle habits and physical fitness across different weight categories of T1DM adolescents from Campania Region. As second aim, we assessed the relationship among lifestyle and physical fitness in these patients. Methods: 74 adolescents (35M; 39F; 13-18 y), with T1DM diagnosed at least 6 mo before the study, were enrolled at the Regional Center for Pediatric Diabetology of Vanvitelli University of Naples. Height, weight, Body Mass Index (BMI), BMI z-score, and Clinical Biochemical health-related parameters were determined. MD adherence, physical activity (PA) amount and sedentary habits were assessed by questionnaires. Handgrip strength, 2-Min Step test (2-MST) cardiorespiratory endurance and Timed up and go test (TUG) for agility and balance were used for physical fitness evaluation. Results: Our sample included 22 normal weight (NW), 37 overweight (OW) and 15 with Obese (Ob) adolescents. Across the three groups, adolescents showed similar Clinical-Biochemical parameters, MD adherence, PA amount, mostly walking (9.3 h/w), daily video exposure (8.5 h/d) and similar handgrip or 2-MST performance. Better performance was observed in NW compared to OW or Ob for TUG (7 vs 8 vs 9 s; p < 0.05). A positive correlation was found between TUG test and BMI, while no correlation was found between HbA1c (glycated haemoglobin) and BMI z score or 2-MST. Conclusions: T1DM adolescents did not meet the recommendations for active lifestyle, despite a medium/good adherence to MD, in particular in NW and OW youths. Sedentary habits correlated with a poor HbA1c. Further, reduced agility and balance were observed in adolescents with obesity compared to NW participants.Future research should be aimed to examine wider samples and to design health promotion interventions for T1DM adolescents.

RESUMO

The goal of this review was to critically evaluate the research on the effects of Spirulina (SP) supplementation on pathological conditions in the general population, considering its antioxidant, immunomodulatory, and anti-inflammatory properties. On a total of 1621 records screened, eighteen studies published between 2001 and 2020 met the inclusion criteria. Despite variability in research methodology and patient conditions, the findings of these studies generally support the benefits of supplementing diet with SP in subjects with both transmittable and non-transmittable diseases. Improvements were found for all the conditions studied, with the only exception of male infertility. However, the number of clinically controlled trials examining the effects of SP on specific health conditions is still very low, and some studies show medium quality. Further research in this field is needed to confirm the possible clinical role of Spirulina supplementation in parallel with medical therapies.

RESUMO

The aim of this review was to appraise the literature on the effects of probiotics supplementation on gastrointestinal (GI) and upper respiratory tract infection (URTI) risk and prognosis in athletes. The search was conducted using the following electronic databases: MEDLINE (PubMed); Web of Science; Scopus; and SPORTDiscus (EBSCO). According to the PRISMA guidelines, randomized controlled studies performed on healthy athletes with a note dose of probiotics supplementation were considered. From the 2304 articles found, after eliminating reviews and studies on animals and unhealthy subjects and after screening of titles and abstracts, 403 studies were considered eligible. From these, in accordance with the inclusion and exclusion criteria, 16 studies were selected, ten of which concerned endurance athletes. The majority of the studies reported beneficial effects of probiotics in reducing the risk of developing the examined infections or the severity of related symptoms. However, due to the differences in formulations used and populations analyzed in the available studies, further research is needed in this field to achieve stronger and more specific evidence.

RESUMO

BACKGROUND: Biofilms have been found growing on implantable medical devices. This can lead to persistent clinical infections. The highly antibiotic-resistant property of biofilms necessitates the search for both potent antimicrobial agents and novel antibiofilm strategies. Natural product-based anti-biofilm agents were found to be as efficient as chemically synthesized counterparts with fewer side effects. In the present study, the effects of limonene as an antibiofilm agent were evaluated on Pseudomonas aeruginosa and Staphylococcus aureus biofilm formed on different surfaces using the CDC model system in continuous flow. The flgK gene and the pilA gene expression in P. aeruginosa, and the icaA gene and eno gene in S. aureus, which could be considered as efficient resistance markers, were studied. METHODS: Mono- and dual-species biofilms were grown on polycarbonate, polypropylene, and stainless-steel coupons in a CDC biofilm reactor (Biosurface Technologies, Bozeman, MT, USA). To evaluate the ability of limonene to inhibit and eradicate biofilm, a sub-MIC concentration (10 mL/L) was tested. The gene expression of P. aeruginosa and S. aureus was detected by SYBR Green quantitative Real-Time PCR assay (Meridiana Bioline, Brisbane, Australia). RESULTS: The limonene added during the formation of biofilms at sub-MIC concentrations works very well in inhibiting biofilms on all three materials, reducing their growth by about 2 logs. Of the same order of magnitude is the ability of limonene to eradicate both mono- and polymicrobial mature biofilms on all three materials. Greater efficacy was observed in the polymicrobial biofilm on steel coupons. The expression of some genes related to the virulence of the two microorganisms was differently detected in mono- and polymicrobial biofilm. CONCLUSIONS: These data showed that the limonene treatment expressed different levels of biofilm-forming genes, especially when both types of strains alone and together grew on different surfaces. Our findings showed that limonene treatment is also very efficient when biofilm has been grown under shear stress causing significant and irreversible damage to the biofilm structure. The effectiveness of the sanitation procedures can be optimized by applying antimicrobial combinations with natural compounds (e.g., limonene).

RESUMO

Arthrospira platensis, also known as spirulina, is currently one of the most well-known algae supplements, mainly due to its high content of bioactive compounds that may promote human health. Some authors have hypothesized that spirulina consumption could protect subjects from exercise-induced oxidative stress, accelerate recovery by reducing muscle damage, and stimulate the immune system. Based on this, the main goal of this review was to critically analyze the effects of spirulina on oxidative stress, immune system, inflammation and performance in athletes and people undergoing exercise interventions. Of the 981 articles found, 428 studies were considered eligible and 13 met the established criteria and were included in this systematic review. Most recently spirulina supplementation has demonstrated ergogenic potential during submaximal exercise, increasing oxygen uptake and improving exercise tolerance. Nevertheless, spirulina supplementation does not seem to enhance physical performance in power athletes. Considering that data supporting benefits to the immune system from spirulina supplementation is still lacking, overall evidence regarding the benefit of spirulina supplementation in healthy people engaged in physical exercise is scarce and not consistent. Currently, spirulina supplementation might be considered in athletes who do not meet the recommended dietary intake of antioxidants. Further high-quality research is needed to evaluate the effects of spirulina consumption on performance, the immune system and recovery in athletes and active people.

RESUMO

INTRODUCTION: Balneotherapy centers of Ischia island (Italy) offer treatments for different dermatological diseases (psoriasis, acne, atopic dermatitis) and upper respiratory tract infections. In this study, we integrated morphological and molecular approaches to give a focus on isolation and screening of extremophile bacteria from Ischia thermal mud for potential antimicrobial applications. METHODS: Samples were collected during 2019 at four sites. Some bacterial strains ATCC for antibacterial and antibiofilm activity were tested. After morphological characterization, screening for antagonistic isolates was made. The colonies isolated from thermal mud samples were submitted to molecular characterization. Susceptibility testing by dilution spotting was carried out and antibacterial efficacies of most active isolate were evaluated with a Minimal inhibition concentration assay. Biofilm formation, inhibition, eradication were examined. Statistical analyses were carried out utilizing Microsoft® Excel 2016/XLSTAT©-Pro. RESULTS: We isolated a natural compound with antimicrobial and antibiofilm activities. CONCLUSIONS: The results obtained in this study are discussed in the context of how hydrothermal systems are important environmental source of uncharted antimicrobial and antibiofilm compounds. In conclusion, to the most effective of our knowledge, this work presents the primary report on the preliminary investigation of thermophile microbial diversity and their antimicrobial and antibiofilm activities for future biotechnological interest.

RESUMO

OBJECTIVE: Adolescents may be vulnerable to misleading nutritional information and adopt unhealthy food habits. In addition, specific features related to physical training, either aimed to improve fitness or to comply with sport demands, may influence food habits of the youth. This cross-sectional study was aimed to compare nutrition knowledge, food habits and adherence to Mediterranean diet in youth engaged in fitness training, competitive sports or inactive. METHODS: Three questionnaires, the General and Sport Nutrition Knowledge (GeSNK) questionnaire, a food habit questionnaire and the KIDMED were administered to gym members, athletes engaged in volleyball, long-distance swimming, and gymnastics, and inactive adolescents. RESULTS: The total sample included 211 youth (age 16.8 ± 1.7 years). Gym members, like the inactive youth, had lower general and sport-related nutrition knowledge compared to athletes (p = 0.001). In the whole sample, general nutrition knowledge was positively associated with healthy food habits (p < 0.01) and adherence to the Mediterranean diet pattern (p < 0.02). CONCLUSIONS: Gym members had a level of nutrition knowledge lower than young athletes and similar to inactive youth. Healthy food habits were related with nutrition knowledge among adolescents. Specific nutritional education programs are needed to address food habits in fitness settings.

RESUMO

Mild cognitive impairment (MCI) defines an intermediate state between normal ageing and dementia, including Alzheimer's disease (AD). Identification of MCI subjects who will progress to AD (MCI-AD) is today of crucial importance, especially in light of the possible development of new pathogenic therapies. Several evidences suggest that miRNAs could play relevant roles in the biogenesis of AD, and the links between selected miRNAs and specific pathogenic aspects have been partly explored. In this study, we analysed the composition of microRNA transcriptome in blood, serum and cerebrospinal fluid samples from MCI-AD subjects, from an enriched small RNA library. Real-time qPCR from MCI-AD and AD patients and normal controls was performed to profile miRNA expression. In particular, four microRNAs, hsa-mir-5588-5p, hsa-mir-3658, hsa-mir-567 and hsa-mir-3908, among all selected microRNAs, are dysregulated. Hsa-mir-567 was found to be differentially expressed in cerebrospinal fluid samples, blood and serum from MCI-AD patients, showing the highest fold change and statistical significance. Target prediction analysis have been performed to evaluate mRNAs whose expression was controlled by miRNAs found to be dysregulated here, showing that hsa-mir-567 target genes are functionally active in neuronal cells. We propose that miRNA profiles found in samples from MCI-AD patients might be relevant for a better understanding of AD-related cognitive decline and could lead to set up suitable and potential biomarkers for MCI-AD progression to AD.

RESUMO

Background: On February 2020, the novel coronavirus (2019-nCoV) epidemic began in Italy. In order to contain the spread of the virus, the Italian government adopted emergency measures nationwide, including closure of schools and universities, workplaces and subsequently lockdown. This survey was carried out among Italian undergraduates to explore their level of knowledge about the epidemic and the behaviors they adopted during the lockdown. Methods: An electronic questionnaire was administered to the students attending three Italian universities. Results: A good level of knowledge about the epidemic and its control was registered in the sample, mainly among students attending life sciences degree courses. The majority of the students did not modify their diet and smoking habits, while a great part of the sample reported a decrease in physical activity (PA). Conclusions: Students from life sciences courses showed a higher awareness regarding the infection and the control measures. The lockdown caused an important reduction of PA. Preventive interventions should transform the restrictive measures also as an opportunity to improve lifestyle.

RESUMO

The aim of this study was to evaluate the correlation between the microbial air contamination values obtained by active sampling (colony-forming units per cubic metre, CFU/m3) and by passive sampling (Index of microbial air contamination, IMA) and to calculate the corresponding equations. Air sampling was performed in ten dental clinics (DC), before (T0), during (T1) and after (T2) the clinical activity, for five consecutive days, once a month for a period of three months, for a total of 450 air samplings. The correlation was evaluated using the Spearman test, and a p value below 0.05 was considered statistically significant. A statistically significant correlation was found considering both the results obtained from the total observations and from the single sampling times, T0, T1 and T2. Different correlation patterns were observed stratifying by DC. Both methods were able to evaluate the microbial air quality and highlight critical situations; therefore, both can be used with this aim. However, in particular during the activity, passive sampling resulted more sensitive, and for its simplicity, economy and standardization by IMA, as suggested by several authors, can be suggested for routine monitoring.

RESUMO

This narrative review aims to critically analyze the effects of exercise on health in aging. Here we discuss the main clinical and biomolecular modifications induced by long-term recreational football training in older subjects. In particular, the effects induced by long-term recreational football training on cardiovascular, metabolic and musculo-skeletal fitness, together with the modifications in the muscle expression of hallmarks related to oxidative metabolism, DNA repair and senescence suppression pathways and protein quality control mechanisms will be provided. All these topics will be debated also in terms of preventing non-communicable metabolic diseases, in order to achieve successful aging over time.

RESUMO

The present study assesses the in vitro antibiofilm potential activity of extracts of wild Allium ursinum and Allium oschaninii. The active ingredients of the extracts were obtained with a technique named Naviglio (rapid solid-liquid dynamic extraction, RSLDE) which is based on an innovative and green solid-liquid extraction methodology. The extracts were tested against models of mono- and polymicrobial biofilm structures of clinically antibiotic-resistant pathogens, Klebsiella pneumoniae ATCC 10031 and Candida albicans ATCC 90028. Biofilms were studied using a static and a dynamic model (microtiter plates and a CDC reactor) on three different surfaces reproducing what happens on implantable medical devices. Antimicrobic activities were determined through minimum inhibitory concentration (MIC), while antibiofilm activity was assessed by minimum biofilm eradication concentration (MBEC) using a crystal violet (CV) biofilm assay and colony forming unit (CFU) counts. Results showed that both Allium extracts eradicated biofilms of the tested microorganisms well; biofilms on Teflon were more susceptible to extracts than those on polypropylene and polycarbonate, suggesting that when grown on a complex substrate, biofilms may be more tolerant to antibiotics. Our data provide significant advances on antibiotic susceptibility testing of biofilms grown on biologically relevant materials for future in vitro and in vivo applications.

RESUMO

PURPOSE: This study aimed to evaluate the prevalence of traits of orthorexia nervosa (ON) and muscle dysmorphia (MD) in a group of undergraduates, investigate the associations between the risk of these conditions and the type of university course attended, the individual characteristics (gender, BMI, amount of physical activity, supplements and medicines use, dieting) and the risk of eating disorders (EDs). METHODS: A self-reported questionnaire consisting of a socio-demographic section and three tests validated for the evaluation of a risk of ON (ORTO-15), MD (MDDI-ITA) and EDs (EAT-26) was completed by 918 students from three Italian universities. RESULTS: 29.0% of participants demonstrated traits of ON and 5.0% of MD, without differences in prevalence in the three areas of study investigated (health-scientific, economic-humanistic, sport sciences); students of sport sciences exhibited a significantly higher score for MDDI-ITA (F = 6.493, p = 0.002). Participants with ON and MD traits were more on a diet (OR = 0.47, p ≤ 0.001 and OR = 0.428, p = 0.020, respectively) and showed a higher prevalence of EDs risk (OR = 3.55, p < 0.001 and OR = 10.23, p ≤ 0.001, respectively). The simultaneous presence of ON, MD, and EDs traits was seen in 5.4% of the students and the three test scores were correlated. CONCLUSIONS: The prevalence of ON and MD traits was found similar to that reported in the literature on undergraduates. Some associations observed improvement in the knowledge about these conditions, especially the association of participants with ON and MD traits with dieting and EDs traits and the correlation of the three test scores suggests a connection among these potential conditions. LEVEL OF EVIDENCE: Level V, descriptive cross-sectional survey.

RESUMO

Two natural mixtures, Allium sativum fermented extract (BGE) and cannabinol oil extract (CBD), were assessed for their ability to inhibit and remove Pseudomonas aeruginosa biofilms on soft contact lenses in comparison to a multipurpose Soft Contact Lens-care solution present on the Italian market. Pseudomonas aeruginosa (ATCC 9027 strain) and Pseudomonas aeruginosa clinical strains isolated from ocular swabs were tested. Quantification of the biofilm was done using the microtiter plate assay and the fractional inhibitory concentration index was calculated. Both forms of Pseudomonas aeruginosa generated biofilms. BGE at minimal inhibitory concentration (MIC) showed inhibition percentages higher than 55% for both strains, and CBD inhibited biofilm formation by about 70%. The care solution at MIC inhibited biofilm formation by about 50% for both strains tested. The effect of BGE on the eradication of the microbial biofilm on soft contact lenses at MIC was 45% eradication for P. aeruginosa ATCC 9027 and 36% for P. aeruginosa clinical strain. For CBD, we observed 24% biofilm eradication for both strains. For the care solution, the eradication MICs were 43% eradication for P. aeruginosa ATCC 9027 and 41% for P. aeruginosa clinical strain. It was observed that both the test soft contact lenses solution/BGE (fractional inhibitory concentration index: 0.450) and the test soft contact lenses solution/CBD (fractional inhibitory concentration index: 0.153) combinations exhibited synergistic antibiofilm activity against most of the studied bacteria. The study showed that BGE and CBD have good effect on inhibition of biofilm formation and removal of preformed biofilms, which makes them promising agents that could be exploited to develop more effective care solutions.

RESUMO

The emerging concern about the increase of antibiotic resistance and associated biofilm has encouraged scientists to look for alternative antibiotics such as antimicrobial peptides (AMPs). This study evaluated the ability of melittin to act as an antibacterial biofilm inhibitor and biofilm remover considering isolates from dairy industry. Minimum inhibitory concentrations (MICs), minimum bactericidal concentrations (MBCs), minimum biofilm inhibitory concentrations (MBICs), and biofilm removal activities were studied in polymicrobial biofilms produced from isolates. MIC and MBC were set at 1-3 µg/mL and 25-50 µg/mL for Gram-positive and Gram-negative bacteria, respectively. Results demonstrated a good MBIC reaching 85% inhibition ability and a good activity and better penetration in deeper layers against the mixed preformed biofilm, thereby increasing its activity against all isolates also at the lowest tested concentrations. Melittin showed interesting characteristics suggesting its potential to act as an antimicrobial agent for polymicrobial biofilm from dairy industry even in environmental isolates.

RESUMO

BACKGROUND: This study aimed to analyze the effects of a long-term community-based combined exercise program consisting of aerobic, resistance, flexibility and agility/balance training associated with motivational interviewing on physical fitness, physiological parameters and Physical Activity (PA) levels in middle-aged and older patients with Type 2 Diabetes (T2D). METHODS: Sixty-nine diabetic subjects (mean age 63 ± 5.2 y, 62.3% M) underwent a 9-month exercise program and 12 motivational group meetings focused on PA, while 90 diabetic controls (mean age 64 ± 6.4 y, 58% M) underwent usual PA recommendations. Changes in physical fitness measured by Senior Fitness Tests, BMI, HbA1c, waist circumference (WC) and habitual PA expressed in Metabolic Equivalent of Tasks (METs)-min/week were evaluated in each group through the International PA Questionnaire and compared between groups. RESULTS: At the end of the intervention participants showed significant improvements in BMI (29.3 to 27.6 kg/m2, P < 0.03), HbA1c (6.5 to 6.1%, P < 0.01), WC (104.2 to 95.6 cm, P < 0.01) and all the physical fitness parameters (P < 0.01) but lower body flexibility (P = 0.82), while only upper body strength (P = 0.04) and agility (P ≤ 0.01) improved significantly in controls. Habitual PA increased in participants and controls (+67 and +19 METs-min/week, respectively, P ≤ 0.01). Changes in physical fitness and PA levels registered in the two groups differed significantly (P < 0.01), while improvements in BMI, HbA1c and WC did not (P = 0.40, P = 0.52, P = 0.05, respectively). CONCLUSIONS: A long-term motivational exercise-based intervention may be more effective than PA recommendations only in improving physical fitness and PA levels in individuals with T2D and produce similar health improvements.

RESUMO

BACKGROUND: Type 2 diabetes (T2D) is associated with a prion diminished quality of life, especially due to the severe complications that it implicates. Changing dietary habits is an absolute priority, as well as implementing nutritional motivational programs. The aim of this study was to verify the effectiveness of a nutritional intervention in improving the health of patients affected by T2D. METHODS: A total of 69 patients participated in a nine-months motivational program focused on the principles of the Mediterranean diet, the classes of nutrients, the distribution of the meals during the day and the dietary choices. During regular meetings, the patients were requested to fill out a questionnaire about their dietary habits and behaviours. Clinical and metabolic parameters were also analysed. RESULTS: At the end of the intervention the number of people who declared that they ate five meals a day (p = 0.006) and preferred to have fruit for snack (p = 0.004) increased, while there was a reduction in the use of sweeteners and an elimination of the use of fructose (p = 0.05). The total daily consumption of kilocalories (kcal) had been reduced and the percentages of carbohydrates, proteins and lipids, after the intervention, follow the guidelines. In relation to this, a significant improvement (p < 0.05) was registered in systolic and diastolic pressure, BMI and waist circumference, as well as in glycaemic values (p = 0.018). CONCLUSIONS: A nutritional motivational intervention may be useful in improving dietary habits and health status of patients with T2D. We hope that a similar intervention will be applied in Campania and in other Italian regions. TRIAL REGISTRATION: Registration number is ISRCTN11067689 ; date of registration: 10/09/2018. Retrospectively registered.
