Exploring the mystical relationship between the Moon, Sun, and birth rate.

OBJECTIVE: The Moon has a noticeable influence on the Earth due to its gravity, the most visible manifestation of which are tides. We aimed to see if the Moon's daily cycle, like the Sun's, affects the prevalence and incidence of childbirth. METHODS: In this retrospective cohort study, we examined all deliveries at the Academic Hospital of Udine between 2001 and 2019. All consecutive singleton pregnancies with spontaneous labor and vaginal delivery were included. RESULTS: During the period, 13,349 singleton pregnancies with spontaneous labor and vaginal delivery were delivered in 6939 days. A significantly higher prevalence of deliveries was found with the Moon above the horizon (50.63% vs. 49.37%, p < 0.05). Moreover, during the day, there was a significantly higher prevalence of deliveries than during nighttime (53.74% vs. 45.79%, p < 0.05). Combining the Moon and Sun altitude, the majority of deliveries were registered when both were above the horizon (27.39% vs. 26.13%, 23.25%, or 23.24%, p < 0.05). These findings were confirmed in multivariate analysis after adjusting for parity, gestational age, or season. We found no correlation between birth and the Moon phase. CONCLUSIONS: Our data support the interaction of the Moon and the Sun in determining the time of birth. More research is needed to understand these phenomena and improve our understanding of labor initiation mechanisms.

Development of a network model to implement the HPV vaccination coverage.

Background: The vaccination coverage of a population is the usual indicator of the effectiveness of vaccination strategies. The study aims to evaluate the effectiveness of an organizational and communication network to implement Human Papilloma Virus (HPV) vaccination coverage both in males and females in the Center Tuscany Local Health Authority. Study design: Experimental study. Materials and methods: In January 2022, a retrospective study was conducted on anti-HPV vaccine coverage (full cycle), of those born from 2007 to 2010, in the Empoli Territorial Area of Florence (240 thousand inhabitants) under the Center Tuscany Local Health Authority. In February 2022, a project (meetings with general practitioners and pediatricians, communication through local media, increased opening hours of vaccination clinics and continuous monitoring of vaccination status) started to recover the females and males non-compliant; in the first five months, in addition to guaranteeing the offer to the reference cohort, it aimed to recover the 2007, 2008 and 2009 cohorts, while in the following six months the anti-HPV vaccine offer was expanded for the 2010 cohort. Results: In January 2022, for all cohorts the average total coverages were 49.2% (49.1% for females and 49.5% for males), while in December 2022 they were 63.9% (65.8% for females and 62.3% for males). Coverage increased by 15.6% (+14.2% for females and +16.8% for males) for the 2007 birth cohort, by 22.3% (+20.6% for females and +23.7% for males) for the 2008 cohort and by 20.9% (+31.4% for females and +10.6% for males) for the 2009 cohort. Conclusions: This model in force in the whole Center Tuscany Local Health Authority for a few years and already activated in the previous Local Health Authority of Empoli, now called Empoli Territorial Area, has allowed to implement the Human Papilloma Virus vaccine coverage for both genders.

Effectiveness of near-UVA in SARS-CoV-2 inactivation.

This experimental study aimed to determine the activity of a near-UVA (405 nm) LED ceiling system against the SARS-CoV-2 virus. The ceiling system comprised 17 near-UVA LED lights with a radiant power of 1.1 W/each centred at 405 nm wavelength. A 96-multiwell plate, fixed to a wooden base, was inoculated with suspensions of VERO E6 cell cultures infected with SARS-CoV-2 virus and irradiated at a distance of 40 cm with a dose of 20.2 J/cm2 for 120 min. The collected suspensions were transferred to VERO cell culture plates and incubated for 3 days. The maximum measurable log reduction obtained, starting from a concentration of 107.2 TCID50/mL, was 3.0 log10 and indicated inhibition of SARS-CoV-2 replication by the near-UVA LED ceiling system. Near-UVA light at a 405-nm wavelength is emerging as a potential alternative treatment for localised infections and environmental decontamination because it is far less harmful to living organisms' cells than UV-C irradiation.

How Physicians Spend Their Work Time: an Ecological Momentary Assessment.

BACKGROUND: Little is known about how physicians spend their work time. OBJECTIVE: To determine how physicians in outpatient care spend their time at work, using an innovative method: ecological momentary assessment (EMA). DESIGN: Physician activity was measured via EMA, using a smartphone app. PARTICIPANTS: Twenty-eight practices across 16 US states. Sixty-one physicians: general internal medicine, family medicine, non-interventional cardiology, orthopedics. MAIN MEASURES: Proportions of time spent on 14 activities within 6 broad categories of work: direct patient care (including both face-to-face care and other patient care-related activities), electronic health record (EHR) input, administration, teaching/supervising, personal time, and other. KEY RESULTS: After excluding personal time, physicians spent 66.5% of their time on direct patient care (23.6% multitasking with use of the EHR and 42.9% without the EHR), 20.7% on EHR input alone, 7.7% on administrative activities, and 5.0% on other activities (0.6% using the EHR). In total, physicians spent 44.9% of their time on the EHR. LIMITATIONS: Unable to measure time spent at home on the EHR or other work tasks; participating physicians were not a random sample of US physicians. CONCLUSIONS: The efficiency of highly trained professionals spending only two-thirds of their time on direct patient care may be questioned. EHR use continues to account for a large proportion of physician time. Further attempts should be made to redesign both EHRs and physician work processes.

Neonatal outcome in pregnancy hypotiroidee women.

To evaluate the impact that hypothyroidism may have on the course of pregnancy and on neonatal outcome. This cross-sectional study consisting of 160 pregnant women (60 with hypothyroidism and 100 as control) who had been hospitalized at the Obstetrics and Gynecology of the University of Siena. The obstetric visit, the collection of anamnestic data and serum concentrations of TSH, FT4 and AbTPO were performed for each woman. Stratification of the population into two groups based on the BMI showed that there is an average difference of -0.88 before pregnancy BMI between healthy women and hypothyroid women. Moreover, with regard to the obstetric history, 8.7 times higher risk of abortion was found in hypothyroid women. About the current pregnancy in hypothyroid women, slight fetal growth delay, increased risk of premature rupture of membranes (PROM), and a higher risk of developing hypertension and gestational diabetes had been found. The importance of a more detailed anamnesis should be evaluated with greater attention at the beginning of pregnancy. This, in order to avoid the risks related to a hypothyroidism condition during pregnancy and to establish an early therapeutic treatment appropriate to the metabolic demands of each patient.

The decomposition of gain in life expectancy in Tuscany Region (Central Italy) for age-group and cause of death.

BACKGROUND: changing of life expectancy at birth (LE) over time is an important indicator of welfare and healthcare infrastructure of a Country. OBJECTIVES: to evaluate the impact of age and cause-specific mortality on the change in LE in the Tuscany Region (Central Italy). DESIGN: the decomposition of LE gain was realized with Pollard's method, using Epidat software. SETTING AND PARTICIPANTS: mortality data relative to residents that died during the period 1987-2015 were provided by the Tuscan Regional Mortality Registry. The analyzed causes of death were cardiovascular (CVS), respiratory (RESP), infective (INF) diseases and cancer (TUM). MAIN OUTCOME MEASURES: changing of LE expressed in years in relation to cause and age-specific mortality. RESULTS: the overall LE gain was 6.5 years for males and 4.3 years for females, the major gain was observed in the age groups 65-89 years (for females 75-89 years) and <1 year. The highest gain (2.6 years) was attributable to the reduction of mortality for CVS, followed by TUM (males: 1.42 vs females: 0.83) and RESP (males: 0.4 vs females: 0.1). The causes responsible for the loss of LE were INF (females: -0.16 vs males: -0.07) and lung cancer in females (-0.13). CONCLUSIONS: the prompt treatment of acute CVS events and prevention (both primary and secondary) are responsible for the gain in LE. The reduction of mortality for TUM can be attributed to the evolution of diagnostic-therapeutic possibilities, but also to the implementation of the cancer screening programmes. Lung cancer was responsible for the loss of LE in Tuscan females; the targeted anti-smoke campaigns should, therefore, be intensified. The INF comported the loss of LE; explainable by diffusion of multi-drug resistant bacteria. The programmes of Hospital Infection Control and Antimicrobial Stewardship should be potentiated to contain the phenomenon.

Gender differences in health expenditure determinants: A follow-up study.

Researchers' aim was to investigate if patients/physicians characteristics could differently affect males/females health care expenditure. In 2009/2010, a health-related-quality-of-life (HRQL) measure was distributed to 887 general practitioners' (GP) patients in Siena's province-Italy. Severity of diseases was calculated through Cumulative Illness Rating Scale Severity Index (CIRS-SI). Information about GPs' gender and age and patients' gender, age, and socio-economic variables were recorded. 2012 data about pharmaceutical, outpatient and hospital expenditure were obtained. Multivariate regression was carried out. In males, hospital expenditure increased with higher CIRS-SI and female GP whilst in females it was not influenced by any of the variables. Outpatient and pharmaceutical expenditure increased with aging, higher CIRS-SI, and lower HRQL and education, both in males and females. Gender differences in health expenditure determinants emerged for hospital expenditure.

Intracellular and Extracellular Recording of Spontaneous Action Potentials in Mammalian Neurons and Cardiac Cells with 3D Plasmonic Nanoelectrodes.

Three-dimensional vertical micro- and nanostructures can enhance the signal quality of multielectrode arrays and promise to become the prime methodology for the investigation of large networks of electrogenic cells. So far, access to the intracellular environment has been obtained via spontaneous poration, electroporation, or by surface functionalization of the micro/nanostructures; however, these methods still suffer from some limitations due to their intrinsic characteristics that limit their widespread use. Here, we demonstrate the ability to continuously record both extracellular and intracellular-like action potentials at each electrode site in spontaneously active mammalian neurons and HL-1 cardiac-derived cells via the combination of vertical nanoelectrodes with plasmonic optoporation. We demonstrate long-term and stable recordings with a very good signal-to-noise ratio. Additionally, plasmonic optoporation does not perturb the spontaneous electrical activity; it permits continuous recording even during the poration process and can regulate extracellular and intracellular contributions by means of partial cellular poration.

Induction of labour: clinical predictive factors for success and failure.

Induction of labour (IOL) is a widely-used practice in obstetrics. Our aim was to evaluate predictors of vaginal delivery in postdate pregnancies induced with prostaglandins. We conducted a retrospective cross-sectional study with analytic component. A total of 145 women, admitted for IOL after the 41st week of gestation, were induced with a vaginal pessary releasing prostaglandins. Type of delivery, whether vaginal or caesarean, was the outcome. Several maternal and foetal variables were investigated. The Kaplan-Maier curves, monovariate and a multivariate logistic regression were carried out. In our population, 80.7% of women had vaginal delivery after the induction. Multiparity and a high Bishop score at the beginning of the IOL were protective factors for a vaginal delivery (respectively OR 0.16, p = .028 and OR 0.62, p = .034) while age >35 years, and the foetal birth weight >3500 g at the birth, resulted in being risk factors for caesarean section (respectively OR 4.20, p = .006 and OR 3.63, p = .013). IMPACT STATEMENT What is already known on this subject: Induction of labour (IOL) is a widely used practice in obstetrics. Scientific literature shows several predictors of successful induction, although there is no unanimity except for 'multiparity' and 'favourable Bishop score' which are associated with positive outcome of the induction. The main difficulty in finding other predictive factors is the heterogeneity of this field (different local protocols in each hospital, type of induction, populations and outcomes chosen in each study). In addition to that, populations are not always comparable due to the different gestation. For this reason, we decided to select a specific population of women, such as low risk postterm pregnancies induced with prostaglandins, in order to detect possible predictive factors for the success of the IOL for women with uncomplicated pregnancies. What the results of this study add: Our study agrees with existing literature that 'multiparity' and 'Bishop score' are linked with the success of IOL and adds that 'maternal age' and 'foetal birth weight' are significant risk factors for the population of uncomplicated post term pregnancies induced with prostaglandins. What the implications are of these findings for clinical practice and/or further research: Our results agreed with the existing literature regarding parity and Bishop score but not for maternal age and birth weight. This adds new precious data to the literature which could be used for systematic reviews and for implementing IOL guidelines and protocols, nationally and internationally. Our findings could be also used for guiding future research in this field. It will be interesting to investigate the existence of not just specific factors but also any combination of variables which could predict the success of the procedure. At the moment these information cannot be used in terms of decision making for healthcare professionals as no variable is 100% predictive but once further research will be added, we may be able to know when is best time to start the IOL, how to facilitate the success of the procedure and how to best support the woman throughout the whole experience.

Patient Discomfort during Carotid Artery Stenting: A Comparison Study between Iodixanol versus Iopamidol.

BACKGROUND: The aim of this study was to compare the adverse effects of iodixanol and iopamidol in terms of patient's discomfort in subjects undergoing carotid artery stenting (CAS). METHODS: We retrospectively analyzed data of all successful CAS procedures performed in our department during a 15-year period study. All patients judged to be collaborative were included. From December 2000 to December 2005, we adopted iopamidol as contrast media (CM), thereafter iodixanol. Any transient unpleasant sensation of bitter taste or warmth perceived by the patient after intra-arterial injection of CM was recorded. Injection-associated discomfort was assessed by visual analog scale (VAS) score. Comparison between the 2 CMs with regard to the overall discomfort was carried out by using the Mann-Whitney test. Spearman correlation was performed to assess the correlation among discomfort, age, and CM used. A univariate analysis was performed for slightly bitter taste and warmth sensation to compare these clinical outcomes and CM used; subsequently, a logistic multivariate analysis regression was performed with the "backward elimination." RESULTS: Data from 1,633 patients were evaluated. A total of 608 patients underwent CAS procedure using iopamidol, and 1,025 using iodixanol. The total amount of CM used during a single procedure was 85 ± 17 mL/patient (range 60-135). The median VAS value was statistically significantly lower in the iodixanol group than in the iopamidol group (P < 0.001). A significant Spearman correlation coefficient was found between age and discomfort for both CMs used (Spearman rho 0.18 for iodixanol, 0.17 for iopamidol). The univariate analysis showed that patients undergoing CAS with iopamidol had an odds ratio (OR) of 8.48 (P < 0.001) to perceive warmth sensation. When adjusted for age and gender, the multivariate analysis still showed an OR of 8.03. For slightly bitter taste sensation, the crude analysis showed an OR of 1.31 (P = 0.018); adjusting for age and gender, OR became 1.15 and the difference was not statistically significant (P = 0.257). CONCLUSIONS: During CAS, less overall discomfort was reported in patients receiving iodixanol than iopamidol; in terms of warmth sensation, patients undergoing procedure using iopamidol as CM have a higher risk to perceive this clinical symptom than iodixanol. Slightly bitter taste seems to have a statistically significant relation with age and gender, and not with CM used.

Morphological modulation of graphene-mediated hybridization in plasmonic systems.

We investigated the plasmonic response of a 2-dimensional ordered array of closely spaced (few-nm apart) Au nanoparticles covered by a large-area single-layer graphene sheet. The array consisted of coherently aligned nanoparticle chains, endowed with a characteristic uniaxial anisotropy. The joint effect of such a morphology and of the very small particle size and spacing led to a corresponding uniaxial wrinkling of graphene in the absence of detectable strain. The deposition of graphene redshifted the Au plasmon-resonance, strongly increased the optical absorption of the array and, most importantly, induced a marked optical anisotropy in the plasmonic response, absent in the pristine nanoparticle array. The experimental observations are accounted for by invoking a graphene-mediated resistive coupling between the Au nanoparticles, where the optical anisotropy arises from the wrinkling-induced anisotropic electron mobility in graphene at optical frequencies.

Cu Vacancies Boost Cation Exchange Reactions in Copper Selenide Nanocrystals.

We have investigated cation exchange reactions in copper selenide nanocrystals using two different divalent ions as guest cations (Zn(2+) and Cd(2+)) and comparing the reactivity of close to stoichiometric (that is, Cu2Se) nanocrystals with that of nonstoichiometric (Cu(2-x)Se) nanocrystals, to gain insights into the mechanism of cation exchange at the nanoscale. We have found that the presence of a large density of copper vacancies significantly accelerated the exchange process at room temperature and corroborated vacancy diffusion as one of the main drivers in these reactions. Partially exchanged samples exhibited Janus-like heterostructures made of immiscible domains sharing epitaxial interfaces. No alloy or core-shell structures were observed. The role of phosphines, like tri-n-octylphosphine, in these reactions, is multifaceted: besides acting as selective solvating ligands for Cu(+) ions exiting the nanoparticles during exchange, they also enable anion diffusion, by extracting an appreciable amount of selenium to the solution phase, which may further promote the exchange process. In reactions run at a higher temperature (150 °C), copper vacancies were quickly eliminated from the nanocrystals and major differences in Cu stoichiometries, as well as in reactivities, between the initial Cu2Se and Cu(2-x)Se samples were rapidly smoothed out. These experiments indicate that cation exchange, under the specific conditions of this work, is more efficient at room temperature than at higher temperature.

Out-of-Plane Plasmonic Antennas for Raman Analysis in Living Cells.

Out-of-plane plasmonic nanoantennas protruding from the substrate are exploited to perform very sensitive surface enhanced Raman scattering analysis of living cells. Cells cultured on three-dimensional surfaces exhibit tight adhesion with nanoantenna tips where the plasmonic hot-spot resides. This fact provides observable cell adhesion sites combined with high plasmonic enhancement, resulting in an ideal system for Raman investigation of cell membranes.

Fistula first, graft on arterialized vein second.

OBJECTIVES: Arterovenous grafts (AVGs) present a feasible solution for creating a vascular access in patients who are unsuitable for autogenous fistula (AVF). The aim of this study is to assess the prevention rate of vein stenosis, placing a graft on an arterialized vein (GAV) instead of an anastomized AVG in a native vein (GNV). METHODS: This was a cohort study conducted from January 2009 to November 2012. All consecutive patients who underwent AVG in our institution were included. All patients requiring a secondary intervention were also referred to our centre. Patients underwent ultrasound follow up at first and the every month. A Kaplan-Meier method was used; a Log-rank test was used to identify whether significant difference existed between GAV and GNV (p < 0.05). RESULTS: Forty-six grafts were placed. Twenty patients had arterialized receiving veins (group A), while 26 patients received an AVG immediately because they lacked autogenous veins suitable for fistula (group B).The average follow-up period was 16.1 months (range 0-41). The group A 41 months-patency rate was 84.3%, while group B was 43.7% (p = 0.06). Secondary patency was similar in the two groups. CONCLUSIONS: Vein arterialization seems to prevent venous stenosis improving AVG-patency rate. More data are needed; however, the borderline p value encourages new studies.

From directive to practice: are pictorial warnings and plain packaging effective to reduce the tobacco addiction?

OBJECTIVES: Tobacco packaging represents an important form of promotion of tobacco products and for this reason plain packaging (PP) can be considered an additional tobacco control measure. In Italy the current tobacco packaging is branded with textual warnings. The study investigated the perception of PP with textual warnings (PPTWs) and pictorial warnings (PPPWs) in Italy. STUDY DESIGN: Cross-sectional. METHODS: The study was conducted on adults who were current, never and former smokers. The participants watched out three types of packages (current packaging, PPTWs and PPPWs) and eight pictorial warnings, and indicated which they considered the most effective ones to motivate smoking cessation or reduction and to prevent the onset. RESULTS: 1065 subjects were recruited. The PPPWs were considered the most effective in motivating to quit, reduce and prevent the smoking habits (ranged 83.4%-96.1%) in all tobacco users and age groups (≤40/>40 years) (P < 0.005). In general PP does not seem to be very effective in quitting for three-quarters of the smokers and 60% declared that they would have still started smoking with PP. The younger group believed less than the older one that PP gives a motivation to quit (29.4% vs 39.1%, P = 0.002). The pictures perceived as most effective in communicating the smoking effects were lung cancer and gangrene (about one-third of the sample). CONCLUSIONS: The textual warnings on tobacco products are a measure of control now outdated. Countries still using them should consider the idea of replace them with pictorial warnings that seem to be more effective. It is also desirable in the near future that these countries introduce the PPPWs.

Sn cation valency dependence in cation exchange reactions involving Cu(2-x)Se nanocrystals.

We studied cation exchange reactions in colloidal Cu(2-x)Se nanocrystals (NCs) involving the replacement of Cu(+) cations with either Sn(2+) or Sn(4+) cations. This is a model system in several aspects: first, the +2 and +4 oxidation states for tin are relatively stable; in addition, the phase of the Cu(2-x)Se NCs remains cubic regardless of the degree of copper deficiency (that is, "x") in the NC lattice. Also, Sn(4+) ions are comparable in size to the Cu(+) ions, while Sn(2+) ones are much larger. We show here that the valency of the entering Sn ions dictates the structure and composition not only of the final products but also of the intermediate steps of the exchange. When Sn(4+) cations are used, alloyed Cu(2-4y)Sn(y)Se NCs (with y ≤ 0.33) are formed as intermediates, with almost no distortion of the anion framework, apart from a small contraction. In this exchange reaction the final stoichiometry of the NCs cannot go beyond Cu0.66Sn0.33Se (that is Cu2SnSe3), as any further replacement of Cu(+) cations with Sn(4+) cations would require a drastic reorganization of the anion framework, which is not possible at the reaction conditions of the experiments. When instead Sn(2+) cations are employed, SnSe NCs are formed, mostly in the orthorhombic phase, with significant, albeit not drastic, distortion of the anion framework. Intermediate steps in this exchange reaction are represented by Janus-type Cu(2-x)Se/SnSe heterostructures, with no Cu-Sn-Se alloys.

Knowledge about tuberculosis among undergraduate health care students in 15 Italian universities: a cross-sectional study.

BACKGROUND: The Italian Study Group on Hospital Hygiene of the Italian Society of Hygiene, Preventive Medicine and Public Health conducted a multicentre survey aiming to evaluate undergraduate health care students' knowledge of tuberculosis and tuberculosis control measures in Italy. METHODS: In October 2012-June 2013, a sample of medical and nursing students from 15 Italian universities were enrolled on a voluntary basis and asked to complete an anonymous questionnaire investigating both general knowledge of tuberculosis (aetiology, clinical presentation, outcome, screening methods) and personal experiences and practices related to tuberculosis prevention. Data were analysed through multivariable regression using Stata software. RESULTS: The sample consisted of 2,220 students in nursing (72.6%) and medicine (27.4%) courses. Our findings clearly showed that medical students had a better knowledge of tuberculosis than did nursing students.Although the vast majority of the sample (up to 95%) answered questions about tuberculosis aetiology correctly, only 60% of the students gave the correct responses regarding clinical aspects and vaccine details. Overall, 66.9% of the students had been screened for tuberculosis, but less than 20% of those with a negative result on the tuberculin skin test were vaccinated. Multivariable regression analysis showed that age and type of study programme (nursing vs. medical course) were determinants of answering the questions correctly. CONCLUSIONS: Although our data showed sufficient knowledge on tuberculosis, this survey underlines the considerable need for improvement in knowledge about the disease, especially among nursing students. In light of the scientific recommendations concerning tuberculosis knowledge among students, progress of current health care curricula aimed to develop students' skills in this field is needed.

Parents' awareness and acceptance of HPV vaccination in Italy.

The aims of this study were to evaluate parents' awareness about HPV infection and vaccination and to identify reasons for not accepting vaccination and the type of health professionals involved in information campaigns. The study involved three schools. Overall, 1200 questionnaires were distributed to parents of female students born between 1993 and 2000 (age 12 to 19 years at the time of the study). The majority of students accepted to be vaccinated. Parents received information from different sources.

Pulsed laser ablation of a continuously-fed wire in liquid flow for high-yield production of silver nanoparticles.

Using wires of defined diameters instead of a planar target for pulsed laser ablation in liquid results in significant increase of ablation efficiency and nanoparticle productivity up to a factor of 15. We identified several competitive phenomena based on thermal conductivity, reflectivity and cavitation bubble shape that affect the ablation efficiency when the geometry of the target is changed. On the basis of the obtained results, this work represents an intriguing starting point for further developments related to the up-scaling of pulsed laser ablation in liquid environments at the industrial level.

Patients' evaluation of hospital foodservice quality in Italy: what do patients really value?

OBJECTIVE: Patients often do not eat/drink enough during hospitalization. To enable patients to meet their energy and nutritional requirements, food and catering service quality and staff support are therefore important. We assessed patients' satisfaction with hospital food and investigated aspects influencing it. DESIGN: We conducted a cross-sectional study collecting patients' preferences using a slightly modified version of the Acute Care Hospital Foodservice Patient Satisfaction Questionnaire (ACHFPSQ). Factor analysis was carried out to reduce the number of food-quality and staff-issue variables. Univariate and multivariate ordinal categorical regression models were used to assess the association between food quality, staff issues, patients' characteristics, hospital recovery aspects and overall foodservice satisfaction (OS). SETTING: A university hospital in Florence, Italy, in the period November-December 2009. SUBJECTS: Hospital patients aged 18+ years (n 927). RESULTS: Of the 1288 questionnaires distributed, 927 were returned completely or partially filled in by patients and 603 were considered eligible for analysis. Four factors (explained variance 64·3 %, Cronbach's alpha α(C) = 0.856), i.e. food quality (FQ; α(C) = 0·74), meal service quality (MSQ; α(C) = 0·73), hunger and quantity (HQ; α(C) = 0·74) and staff/service issues (SI; α(C) = 0·65), were extracted from seventeen items. Items investigating staff/service issues were the most positively rated while certain items investigating food quality were the least positively rated. After ordinal multiple regression analysis, OS was only significantly associated with the four factors: FQ, MSQ, HQ and SI (OR = 17·2, 6·16, 3·09 and 1·75, respectively, P < 0·001), and gender (OR = 1·53, P = 0·024). CONCLUSIONS: The most positively scored aspects of foodservice concerned staff/service, whereas food quality was considered less positive. The aspects that most influenced patients' satisfaction were those related to food quality.
