The QUOVADIS Study: features of obese Italian patients seeking treatment at specialist centers
Obesity is a major risk factor for several chronic diseases, but the burden associated with it
also extends to psychosocial areas and to perceived health status. In 1999 an observational study on healthrelated
quality of life in obesity was planned. The study was entirely web-based. Case Report Forms and
the individual items of 7 self-administered questionnaires were directly implemented on a general database
via an extranet system from 25 Italian centers. By December 2001, after enrolment had stopped, the
database included anthropometric, socioeconomic and clinical data of 1944 patients (78% females). Weightcycling
was reported in over 80% of cases, overeating in 60-65%, structured physical activity in only 13-
15%. Several chronic illnesses were associated. Whereas the prevalence of diabetes and hypertension was
related to the degree of obesity, hyperlipidemia and coronary heart disease did not increase further with
increasing obesity. A disturbed psychological mood was twice more common in females. Concern for present
health was the main reason for seeking treatment in both genders; concern for body appearance was
more common in females. Male subjects were more frequently assigned to dietary counseling and physical
exercise, whereas in females psychotherapy was more frequently considered. Various forms of behavioral
approach were planned in approximately 50% of patients. Finally, very few patients were initially
considered for pharmacological intervention or bariatric surgery. The study provides a comprehensive
picture of Italian patients seeking treatment for obesity. Data on perceived health status, psychological
well being, body image awareness, eating behavior disorders and psychopathological distress will
provide clues to a comprehensive assessment of obesity, the effects of treatments and reasons for failure
Weight cycling in treatment-seeking obese persons: data from the QUOVADIS study
OBJECTIVE: To determine parameters of weight history useful for the assessment of weight cycling and their association with
psychological distress and binge eating.
DESIGN: Cross-sectional.
SUBJECTS: A total of 1889 treatment-seeking obese subjects, enrolled by 25 Italian centers (78% female subject), aged 20–65 y
(median 45); 1691 reported previous efforts to lose weight (median age of first dieting, 30 y).
MEASUREMENTS: The number of yearly attempts to lose weight, weight gain since age 20 y, cumulative weight loss and
gain were checked by a predefined structured interview. Psychological distress was tested by means of Symptom Check-List 90
(SCL-90), Binge Eating Scale (BES) and Three Factor Eating Questionnaire (TFEQ).
RESULTS: Differences in anthropometric, clinical and psychological parameters were observed in relation to previous attempts
to lose weight. Patients in the upper quartile of parameters of weight history were considered weight cyclers. In multivariate
logistic regression analysis, after correction for age, sex and BMI, a high BES score was the only factor systematically associated
with a high frequency of dieting (OR, 1.70; 95% confidence interval, 1.22–2.36; P¼0.022), with higher cumulative weight loss
(1.42; 1.12–1.80; P¼0.003) and cumulative weight gain (1.38; 1.06–1.79; P¼0.017). However, the sensitivity, specificity and
positive predictive value of a high BES score were very low to detect cyclers. Weight cycling did not carry a higher risk of
complicating diseases.
CONCLUSIONS: Weight cycling is associated with psychological distress, and binge eating independently increases the risk, but
cannot be used to predict cycling. Also, obese patients who do not experience overeating as a loss of control discontinue
treatment or regain weight following therapy
Multicenter randomized, double-blind controlled trial to evaluate the efficacy of laser therapy for the treatment of severe oral mucositis induced by chemotherapy in children: laMPO RCT
Objectives: To demonstrate the efficacy of laser photobiomodulation (PBM) compared to that of placebo on severe oral mucositis (OM) in pediatric oncology patients. The primary objective was the reduction of OM grade (World Health Organization [WHO] scale) 7 days after starting PBM. Secondary objectives were reduction of pain, analgesic consumption, and incidence of side effects. Methods: One hundred and one children with WHO grade\ua0>\ua02 chemotherapy-induced OM were enrolled in eight Italian hospitals. Patients were randomized to either PBM or sham treatment for four consecutive days (days +1 to +4). On days +4, +7, and +11, OM grade, pain (following a 0\u201310 numeric pain rating scale, NRS) and need for analgesics were evaluated by an operator blinded to treatment. Results: Fifty-one patients were allocated to the PBM group, and 50 were allocated to the sham group. In total, 93.7% of PBM patients and 72% of sham patients had OM grade\ua0<\ua03 WHO on day +7 (P\ua0=\ua00.01). A significant reduction of pain was registered on day +7 in the PBM versus sham group (NRS 1 [0\u20133] vs. 2.5 [1\u20135], P\ua0<\ua00.006). Reduced use of analgesics was reported in the PBM group, although it was not statistically significant. No significant adverse events attributable to treatment were recorded. Conclusions: PBM is a safe, feasible, and effective treatment for children affected by chemotherapy-induced OM, as it accelerates mucosal recovery and reduces pain

Metabolic syndrome, psychological status and quality of life in obesity: the QUOVADIS Study
Objective: We aimed to investigate the association of the clinical variables of the metabolic syndrome (MS) and psychological
parameters on health-related quality of life (HRQL) in obesity. In particular, our aim was to investigate the relative impact
of physical symptoms, somatic diseases and psychological distress on both the physical and the mental domains of HRQL.
Design: Cross-sectional study.
Subjects: A cohort of 1822 obese outpatients seeking treatment in medical centers.
Measurements: HRQL was measured by the standardized summary scores for physical (PCS) and mental (MCS) components of
the Short Form 36 Health Survey (SF-36). Patients were grouped according to tertiles of PCS and MCS. Metabolic and
psychological profiles of PCS and MCS tertiles were compared by discriminant analysis.
Results: The profile of metabolic and psychological variables was tertile-specific in 62.4 and 68.3% of patients in the lowest and
highest tertiles of PCS, respectively, while concordance was low in the mid-tertile (32.8%). Concordance was very high in the
lowest (74.4%) and in the highest (75.5%) tertiles of MCS, and was fair in the mid-tertile (53.2%). The main correlates of PCS
were obesity-specific and general psychological well-being, BMI, body uneasiness, binge eating, gender and psychiatric distress.
Only hypertension and hyperglycemia qualified as correlates among the components of MS. The components of MS did not
define MCS.
Conclusions: Psychological well-being is the most important correlate of HRQL in obesity, both in the physical and in the mental
domains, whereas the features of MS correlate only to some extent with the physical domain of HRQL
Co-Administration of IL-1+IL-6+TNF-α with Mycobacterium tuberculosis Infected Macrophages Vaccine Induces Better Protective T Cell Memory than BCG
BCG has been administered globally for more than 75 years, yet tuberculosis (TB) continues to kill more than 2 million people annually. Further, BCG protects childhood TB but is quite inefficient in adults. This indicates that BCG fails to induce long-term protection. Hence there is a need to explore alternative vaccination strategies that can stimulate enduring T cell memory response. Dendritic cell based vaccination has attained extensive popularity following their success in various malignancies. In our previous study, we have established a novel and unique vaccination strategy against Mycobacterium tuberculosis (M. tb) and Salmonella typhimurium by utilizing infected macrophages (IM). In short-term experiments (30 days), substantial degree of protection was observed. However, remarkable difference was not observed in long-term studies (240 days) due to failure of the vaccine to generate long-lasting memory T cells. Hence, in the present study we employed T cell memory augmenting cytokines IL-1+IL-6+TNF-α and IL-7+IL-15 for the induction of the enhancement of long-term protection by the vaccine. We co-administered the M. tb infected macrophages vaccine with IL-1+IL-6+TNF-α (IM-1.6.α) and IL-7+IL-15 (IM-7.15). The mice were then rested for a reasonably large period (240 days) to study the bona fide T cell memory response before exposing them to aerosolized M. tb. IM-1.6.α but not IM-7.15 significantly improved memory T cell response against M. tb, as evidenced by recall responses of memory T cells, expansion of both central as well as effector memory CD4 and CD8 T cell pools, elicitation of mainly Th1 memory response, reduction in the mycobacterial load and alleviated lung pathology. Importantly, the protection induced by IM-1.6.α was significantly better than BCG. Thus, this study demonstrates that not only antigen-pulsed DCs can be successfully employed as vaccines against cancer and infectious diseases but also macrophages infected with M. tb can be utilized with great efficacy especially in protection against TB
IL-12 and GM-CSF in DNA/MVA Immunizations against HIV-1 CRF12_BF Nef Induced T-Cell Responses With an Enhanced Magnitude, Breadth and Quality
In Argentina, the HIV epidemic is characterized by the co-circulation of subtype B and BF recombinant viral variants. Nef is an HIV protein highly variable among subtypes, making it a good tool to study the impact of HIV variability in the vaccine design setting. We have previously reported a specific cellular response against NefBF with low cross-reactivity to NefB in mice. The aim of this work was to analyze whether the co-administration of IL-12 and GM-CSF, using DNA and MVA vaccine vectors, could improve the final cellular response induced. Mice received three DNA priming doses of a plasmid that express NefBF plus DNAs expressing IL-12 and/or GM-CSF. Afterwards, all the groups were boosted with a MVAnefBF dose. The highest increase in the magnitude of the NefBF response, compared to that induced in the control was found in the IL-12 group. Importantly, a response with higher breadth was detected in groups which received IL-12 or GM-CSF, evidenced as an increased frequency of recognition of homologous (BF) and heterologous (B) Nef peptides, as well as a higher number of other Nef peptide pools representing different viral subtypes. However, these improvements were lost when both DNA cytokines were simultaneously administered, as the response was focused against the immunodominant peptide with a detrimental response towards subdominant epitopes. The pattern of cytokines secreted and the specific-T-cell proliferative capacity were improved in IL-12 and IL-12+GM-CSF groups. Importantly IL-12 generated a significant higher T-cell avidity against a B heterologous peptide
The Lysosome and Intracellular Signalling.
In addition to being the terminal degradative compartment of the cell's endocytic and autophagic pathways, the lysosome is a multifunctional signalling hub integrating the cell's response to nutrient status and growth factor/hormone signalling. The cytosolic surface of the limiting membrane of the lysosome is the site of activation of the multiprotein complex mammalian target of rapamycin complex 1 (mTORC1), which phosphorylates numerous cell growth-related substrates, including transcription factor EB (TFEB). Under conditions in which mTORC1 is inhibited including starvation, TFEB becomes dephosphorylated and translocates to the nucleus where it functions as a master regulator of lysosome biogenesis. The signalling role of lysosomes is not limited to this pathway. They act as an intracellular Ca2+ store, which can release Ca2+ into the cytosol for both local effects on membrane fusion and pleiotropic effects within the cell. The relationship and crosstalk between the lysosomal and endoplasmic reticulum (ER) Ca2+ stores play a role in shaping intracellular Ca2+ signalling. Lysosomes also perform other signalling functions, which are discussed. Current views of the lysosomal compartment recognize its dynamic nature. It includes endolysosomes, autolysosome and storage lysosomes that are constantly engaged in fusion/fission events and lysosome regeneration. How signalling is affected by individual lysosomal organelles being at different stages of these processes and/or at different sites within the cell is poorly understood, but is discussed
Geoeconomic variations in epidemiology, ventilation management, and outcomes in invasively ventilated intensive care unit patients without acute respiratory distress syndrome: a pooled analysis of four observational studies
Background: Geoeconomic variations in epidemiology, the practice of ventilation, and outcome in invasively ventilated intensive care unit (ICU) patients without acute respiratory distress syndrome (ARDS) remain unexplored. In this analysis we aim to address these gaps using individual patient data of four large observational studies. Methods: In this pooled analysis we harmonised individual patient data from the ERICC, LUNG SAFE, PRoVENT, and PRoVENT-iMiC prospective observational studies, which were conducted from June, 2011, to December, 2018, in 534 ICUs in 54 countries. We used the 2016 World Bank classification to define two geoeconomic regions: middle-income countries (MICs) and high-income countries (HICs). ARDS was defined according to the Berlin criteria. Descriptive statistics were used to compare patients in MICs versus HICs. The primary outcome was the use of low tidal volume ventilation (LTVV) for the first 3 days of mechanical ventilation. Secondary outcomes were key ventilation parameters (tidal volume size, positive end-expiratory pressure, fraction of inspired oxygen, peak pressure, plateau pressure, driving pressure, and respiratory rate), patient characteristics, the risk for and actual development of acute respiratory distress syndrome after the first day of ventilation, duration of ventilation, ICU length of stay, and ICU mortality. Findings: Of the 7608 patients included in the original studies, this analysis included 3852 patients without ARDS, of whom 2345 were from MICs and 1507 were from HICs. Patients in MICs were younger, shorter and with a slightly lower body-mass index, more often had diabetes and active cancer, but less often chronic obstructive pulmonary disease and heart failure than patients from HICs. Sequential organ failure assessment scores were similar in MICs and HICs. Use of LTVV in MICs and HICs was comparable (42\ub74% vs 44\ub72%; absolute difference \u20131\ub769 [\u20139\ub758 to 6\ub711] p=0\ub767; data available in 3174 [82%] of 3852 patients). The median applied positive end expiratory pressure was lower in MICs than in HICs (5 [IQR 5\u20138] vs 6 [5\u20138] cm H2O; p=0\ub70011). ICU mortality was higher in MICs than in HICs (30\ub75% vs 19\ub79%; p=0\ub70004; adjusted effect 16\ub741% [95% CI 9\ub752\u201323\ub752]; p<0\ub70001) and was inversely associated with gross domestic product (adjusted odds ratio for a US$10 000 increase per capita 0\ub780 [95% CI 0\ub775\u20130\ub786]; p<0\ub70001). Interpretation: Despite similar disease severity and ventilation management, ICU mortality in patients without ARDS is higher in MICs than in HICs, with a strong association with country-level economic status.
