Background: the emergency due to SARS-CoV-2 pandemic struck the national and regional health system that needed an effort to reorganise and increase resources to cope with a sudden, uncertain, and previously unknown situation. This study was conducted in the immediate aftermath of this difficult period., Objectives: to describe clinical characteristics, short-term outcomes, and management of SARS-CoV-2 positive patients that accessed the emergency department (ED) of the San Luigi Gonzaga hospital of Orbassano (Turin district, Piedmont Region, Northern Italy) in March and April 2020. Furthermore, this study aimed at investigating if a difference in patients characteristics, clinical management, and outcomes was present during time., Design: comparison of different periods in a clinical cohort., Setting and Participants: for each patient who accessed the ED and tested positive for SARS-CoV-2 swab, the ED medical record was collected and a descriptive analysis was performed on demographical characteristics, pre-existing comorbidities, parameters measured at triage, imaging exams results, lab tests results, separately for patients admitted at the ED in four different periods., Main Outcome Measures: discharge from ED, admission to hospital wards (low and high intensity of care), short term in-hospital mortality, hospital length of stay. The association between patients' characteristics and the main outcomes was measured using multivariable logistic models., Results: age of patients increased significantly from March to April, together with female prevalence and associated comorbid conditions. A significant difference in symptoms at presentation was not observed nor it was in laboratory test results. Severity at triage and need of intensive care resources were higher in the first weeks, together with the typical clinical presentation with respiratory failure and imaging with signs of bilateral interstitial pneumonia. Accordingly, in-hospital mortality was higher in the first period. Nevertheless, nearly half of patients in the first period were discharged directly from ED showing mild COVID-19 cases. On the contrary, in April an increasing need of hospitalisation in low intensity of care beds was observed, whereas mild cases stopped to access the ED., Conclusions: the results of this study suggest that in few weeks of COVID-19 epidemic both management of the patients at the hospital level - and probably at territorial level resulting in a different population who accessed to the ED - and the clinical characteristics of the COVID-19 patients changed.

Background: The healthcare sector is among the most complex ones where partnerships and interdependencies between different hospitals can achieve real technical and managerial operational models aimed at optimizing resources. However, the construction of this type of interdependence is not simple to implement, making it necessary to integrate at different organizational and professional levels. The aim of this work is to present the integration process and results achieved during the first 3 years of experience after a synergic integration of the interventional cath lab units of the San Luigi Gonzaga University Hospital, Orbassano and the Infermi Hospital Local Health Unit TO 3, Rivoli., Methods: Starting from March 2016, data concerning number and type of procedures as well as the distribution of workloads of each operator in the two cath labs were recorded and monitored. Moreover, numbers of urgent procedures performed as well as the door-to-balloon time in case of primary angioplasty were recorded., Results: Compared to the first 12 months of non-integrated activity, the number of procedures remained constant with an overall trend of activity increase (total procedures: +2.6% from 2016 to 2017; +8.7% from 2017 to 2018). No statistically significant differences were found in the average door-to-balloon time, either by stratifying by period (year 2015 vs 2016 vs 2017 vs 2017 vs 2018) or by single institution. All ST-elevation myocardial infarctions were treated at the arrival site, displacing the medical availability team. The mortality rate and the number of complications were not different compared to the trend recorded in previous years. The implementation of joint programs with an exchange of expertise between operators has allowed the rapid development of skills necessary for the execution of structural heart procedures not previously performed in one of the operating centers., Conclusions: The model of an integrated cath lab unit represents an example of a partnership between two hospitals, which allows a synergistic growth of professional skills, even facing daily logistical challenges. The integration has made it possible to expand the number and type of procedures performed as well to join the on-call equipe without impacting on the door-to-balloon time in case of primary coronary angioplasty.

Overcrowding in Emergency Departments (ED) is a common phenomenon worldwide, especially in metropolitan areas. The main reason for overcrowding is not inappropriate emergency department use by patients but rather a shortage of available hospital beds which results in extended ED stays for patients who need emergency admission. The aims of this study, conducted at the San Giovanni Battista (Molinette) University hospital in Turin (Italy), were a) to verify the existence of overcrowding in the hospital ED and b) to test whether, as stated in the literature, overcrowding is due to restricted access to hospital beds for patients needing emergency admission, and to identify contributing factors. Results show the existence of overcrowding and confirm the hypothesized cause.

Objective: To describe preoperative evaluation in the San Giovanni Battista Hospital in Turin and to forecast the economic impact when preoperative assessment guidelines are implemented., Design: We enrolled, in a month, 702 consecutive patients, excluding cardiac, thoracic, neuro- and vascular surgery, as well as emergency operations. Preoperative assessment data were collected individually, followed by simulating various applications of guidelines based on: (i) preoperative tests relying on full medical history and physical examination to discriminate preoperative risk patients; (ii) organization of a preoperative evaluation unit and tests before patient hospitalization., Main Measures: Mean number of tests prescribed, preoperative assessment cost per patient., Results: The application of preoperative guidelines would decrease the mean number of tests prescribed from 20 laboratory and 1.9 instrumental to, respectively, 3 and 1.4 per patient. Tests deemed inappropriate by guidelines did not add any relevant clinical information to our study. Economic analysis estimates a reduction of 63% in cost per patient for preoperative tests by introducing guideline criteria (from 69 euros to 26 euros). As regards the cost per patient for preoperative evaluation and hospital stay (115 euros considering only variable costs, 580 euros including all costs), the application of the guidelines would reduce costs by 41-52% according to different cost evaluation approaches for hospital stay., Conclusion: Preoperative guidelines fully introduced in practice could notably increase efficiency without affecting the quality of care.

Using discharge abstract data, we analysed hospital mortality comparing four different methods of risk adjustment. All patients discharged from the S. Giovanni Battista (Molinette) hospital in Turin (Italy) between January 1996 and June 1999 (n = 169,746) were classified with All Patient Refined--Diagnosis Related Groups (APR-DRG). A first analysis evaluated the time trend of hospital mortality by semester. A second analysis compared hospital mortality during the last 12 months among eight units of internal medicine (n = 5592). All comparisons were made through logistic regression models. As the quality of discharge abstracts increased during time and showed variation among units with similar patients, all comparisons were repeated using four models, characterised by increasing predictivity and sensitivity to quality of data. In addition to crude comparisons (A), the other models included as risk factors: B) age and emergency admission; C) same as 'B' plus expected mortality by APR-DRG; D) same as 'B' plus expected mortality by APR-DRG and risk of death subclass. If no risk factors were considered (A), hospital mortality showed an increasing trend, with an odds ratio (OR) of 1.02 by semester, with a 95% confidence interval (CI) between 1.01 and 1.03. The association was weakened when age and mode of admission were taken into account (B) and disappeared when the APR-DRG expected mortality was also considered (C) (OR = 1.00; CI = 0.98-1.01). Finally, if the comparisons were adjusted also for the expected mortality by APR-DRG and risk of death subclass (D) a reversed trend appeared (OR = 0.95; CI = 0.94-0.97). The comparison among the units of internal medicine gave discordant results according to the method used to adjust for confounders. The most striking variations were detected for those units with the best and the worst clinical data. The unit with the poorer clinical data (average number of diagnoses per patient = 2.9) showed a crude OR of 1.38 (CI = 0.99-1.93) and an adjusted OR (D) of 1.71 (CI = 1.10-2.66); the unit with the best quality of data (average number of diagnoses per patient = 4.4) changed the OR from 1.55 (CI = 1.06-2.26) (A) to 0.66 (CI = 0.37-1.17) (D). In conclusion, these results confirm the high sensitivity of the APR-DRG classification to the quality of data and, more in general, suggest to be prudent when using powerful instruments like this to assess quality of care, especially if the quality of data among the units compared is less than optimal or not homogeneous.

Data available from the standard hospital discharge database (SDO) allow us to explore differences in health conditions according to different indicators of socioeconomic status (SES). We analysed all the patients aged 30-59, discharged from the S. Giovanni Battista (Molinette) hospital (the main general hospital in Turin, Italy) during three years (1996-1998) (n = 49949). Three health indicators were used as outcomes: a) emergency admission; b) severity of illness (according to the "All Patient Refined DRGs" subclasses); c) hospital mortality. Patients were compared for each outcome according to two different SES indicators: a) level of education; b) employment status. Logistic regression models (both conditional and unconditional) were used to adjust for several potential confounders. Patients with lower education (up to 5 years of schooling), compared to those with 13 or more years of schooling, showed a higher probability of being admitted through the emergency ward (29.1% vs 23.3%), with an odds ratio (OR) = 1.56-95% confidence interval (95% CI) = 1.45-1.68; of being classified in higher severity subclasses of illness (23.3% vs 17.7%, OR = 1.14; 95% CI = 1.07-1.22) and of dying in hospital (2.3% vs 1.6%). However, after adjustment for other prognostic factors (as severity of illness and specific expected mortality), this association disappeared (OR = 1.05, 95% CI = 0.84-1.32). Similar, but somewhat stronger, associations were observed when comparing the unemployed versus the employed. The corresponding figures (ORs; 95% CI) were 1.57 (1.42-1.74) for emergency admission; 1.31 (1.18-1.45) for severity of illness and 1.55 (1.10-2.16) for hospital mortality. In conclusion, this study showed that SES differentials in health are clearly measurable through routine hospital information systems, and documented that patients of low SES, particularly unemployed, experienced a delayed access to hospital, were admitted in poorer general health conditions and had a more unfavourable prognosis.

In this study the authors considered the effectiveness of thymus hormone in the prevention of acute infections within a group of elderly subjects affected by COPD. Ten subjects were considered, nine males and one female in the age included between 65 and 89 years (medium age = 70.2 +/- 6.96 years), with clinical evaluation and altered functional respiratory tests (FEV1 < 70%). The patients were treated with timopentina 50 mg s c three times a week for a month. The following parameters were considered: leucocytes/mm3; lymphocytes/mm3 in standard conditions, in the first and in the second month after the therapy start, contagious episodes two months before and two months after the beginning of therapy. The Authors noticed a real reduction in the relapses of the infectious episodes (11 relapses in the months before therapy and 2 relapses after therapy had begun). Leucocytes/mm3 rates were reduced (8.070 +/- 3.414 in standard conditions, 6.420 +/- 1.041 after 60 days; 0.2 < P < 0.1). Lymphocytes/mm3 rates were increased, 1.579 +/- 752 in standard conditions, 2103 +/- 491 after 60 days 0.2 < P < 0.1). These preliminary data seem to show in the small number of cases considered, the effectiveness of the thymus hormone (thymopentina) in elderly subjects affected by COPD.

The microbiological, kinetic and clinical profile of cefixime, a IIIrd generation cephalosporin, administered orally, is presented. Cefixime is highly active versus Gram-negative aerobic bacteria while, with respect to Gram-positive bacteria, it is only active against Str. pneumoniae, Str. pyogenes, Str. agalactiae, and Str. bovis. It has no action against anaerobics. Endowed with good kinetics, cefixime possesses a favourable tissue distribution. Cefixime is highly indicated in infections of the upper and lower airways where the aethiology is prevalently due to Str. pneumoniae, H. influenzae and B. catarrhalis, that are extremely sensitive to the antibiotic. It is concluded that the therapeutic armamentarium has been enriched by a new, highly active antibiotic that, administered in a monodese/die, ca satisfy patient compliance.

After a brief introduction on the role of the immune system, the paper illustrates the methods of IgA production and their local protective functions. Those pathologies in which the monitoring of IgA levels plays a diagnostic and prognostic role are also described. In conclusion, the current methods used for the correct evaluation of IgA2 titres are discussed: RIA and competitive immunoenzymatic and immunofluorescent tests, although the latter can only be used on biopsy tissue.

The variation of granulocyte phagocytosis after antibiotic treatment has been studied. The conclusion is drawn that cephalosporins, piperacillin and aztreonam cause an increase of phagocytosis, while rifampicin and gentamicin induce a decrease of this activity.

A human acute T lymphoblastic leukemia line (PF-382) was serially transplanted into nude mice. No takes were observed in untreated nude mice, whereas solid tumors were observed in splenectomized and total body, sublethally irradiated mice. The minimal tumor-inducing dose and the latency time remained unchanged after the third and fifth serial transplants. Moreover, leukemic cells recovered from the 8th in vivo passages displayed the same differentiation antigens and chromosomal markers as the in vitro PF-382 cell line used for the first transplant. This stable and well-characterized experimental system could be a new model for T-lymphocyte differentiation and immune-reactivity against human leukemias.

Certain clinical and epidemiological findings among 2262 AVH patients are reported. The patients were all admitted to the A. di Savoia Hospital for Infectious Diseases in Turin over a two-year period.

An assay of Kininase II activity in the serum of 92 jaundice patients revealed a significant difference between the group with viral hepatitis (268.48 +/- 70.93 U/ml), that with biliary obstructions (133.05 +/- 37.64 U/ml) and with cirrhosis (173.76 +/- 79.56 U/ml). The increase encountered in patients with medical jaundice correlates well with total bilirubinaemia but not with cytolysis enzymes. This suggests failed demolition of ACE by the hepatocyte during cellular stress.

A new synthetic derivative, N-alpha-5 (1,6-dihydro-6-oxo-9-purinyl) pentyloxy-carbonyl-L-arginine (PCF-39) has been evaluated in vitro and in vivo in order to clarify its immunopharmacologic profile. In vitro, PCF-39 did not modify spleen cell functions, whereas parenteral administration in mice of 2.5 and 25 mg/kg (50 and 500 micrograms/mouse) induced an increase in spleen and lymph node cellularity that resulted in a significant resistance to the growth of two distinct syngeneic transplanted tumors. These in vivo findings show that PCF-39 is a potent immunotherapeutic agent with an antitumor effect.

In recent years many clinical trials were carried out in order to evaluate the efficacy of single dose therapy in lower urinary tract infections (UTIs). In this trial we treated 26 patients (5 M and 21 F) suffering from lower UTI with an single oral dose of 3 g of fosfomycin trometamol, a new phosphonic acid derivative. The overall cure rate four weeks after treatment was 77% (20 out of 26 patients). A cure rate of 89% (16 out of 18 patients) was observed in adult females with uncomplicated UTI. No patients complained of side effects due to fosfomycin trometamol.

Urinary enzyme excretion was studied in 56 patients treated with cephalosporins in order to evaluate their potential nephrotoxicity. Only in 4 out of 56 patients (7%) was increased NAG, gamma-GT, AlP excretion seen. A rapid return to normal values was observed just after the end of the therapy.

After a brief review of the data on cefotiam in the literature the report presents the results of microbiological research, a preliminary study into the drug's possible actions on phagocytosis and a polycentric clinical study of 93 cases of broncho-pleuro-pulmonary pathology and one sinusitis of the jaw. In vitro cefotiam was found to have an excellent inhibitory effect on gram positive and gram negative bacteria with MICs50 and 90 respectively 0.2 and 0.8 mcg/ml V. Staph. aureus, Str. pyogenes. E. Coli, K. pneumoniae and Pr. mirabilis. A dose-dependent increase in phagocytosis was noted. The clinical response was excellent with 90.43% (88/94) of the cases achieving clinical and radiological cure or very much improved. Cefotiam was very well tolerated with the appearance of 2/94 skin rashes (2.12%). The liver and kidney parameters showed no change at the end of treatment. No increase in enzymuria was noted during treatment with cefotiam.

In vitro cefoperazone proved more active against the tested gram-negative bacteria than either piperacillin or mezlocillin. When administered in 1 g venous bolus the antibiotic achieved high plasmatic concentrations that were still adequate after 8 hours. 33.2% was excreted by the kidneys and a considerable amount by the biliary way. Cefoperazone produced a clinical cure in 35/36 patients (97.22%). A disulfiram-like effect was noted in 18.18%.

Clinical research was conducted to evaluate the comparative therapeutic efficacy in respiratory pathology of 800 mg X 2 per diem bacampicillin v. 1000 mg X 2 per diem amoxicillin, both orally administered. The results were more or less identical and are interpreted as indicating the better constant absorption of the precursor, hence its higher concentration gradient that produces a higher antibiotic concentration in the lungs.

This paper examines the effect of prolonged daily administration of Vitamin A on NK activity. A placebo and a pill containing 50,000 IU retinol acetate (RA) were taken daily for 120 days by 5 and 6 healthy volunteers respectively. NK activity was determined on days -45, -40, -30 and -10 to calculate each volunteer's inherent variability and then twice a month throughout the administration period. To minimize the experimental variability, an internal control was inserted in each assay. This consisted of two lymphocyte preparations from two healthy individuals divided into cryopreserved aliquots. The cytotoxicity percentage in each assay was corrected against these reference standards and converted into NK values by angular transformation. No increase in NK activity was noted during the study in the group receiving RA. A marked individual variability, however, was noted in both groups.
