Workplace violence among healthcare workers, a multicenter study in Italy.

OBJECTIVES: The purpose of this study is to assess the prevalence and determinants of workplace violence and the sociodemographic risk factors associated. STUDY DESIGN: This was a multicenter cross-sectional study. METHODS: The study was performed using self-compiled Italian version of the World Health Organization's questionnaire on workplace violence online by filling in a Google form. The survey was opened from May 2018 to March 2020 and lasted 5-10 min. RESULTS: The sample consists of 3659 healthcare workers, of which 2525 (69%) are females, 1446 (39.5%) are nurses, and 2029 (55.5%) are health workers from northern Italy. The most frequent age group of the sample is 50-54 years (16.7%). A total of 366 (10%) healthcare workers are victims of physical aggression at work in the last 12 months, of which 6.3% with a weapon. The risk of being a victim of physical aggression at work in the last 12 months is significantly associated with the following independent variables: male gender (odds ratio [OR] 1.72, 95% confidence interval [CI]: 1.36-2.17), work in southern Italy (OR 1.59, 95% CI: 1.10-2.28), and being a nurse (OR 2.56, 95% CI: 2.01-3.25). The risk of being a victim of physical aggression at work with a weapon in the last 12 months is significantly associated with work in southern Italy (OR 9.33, 95% CI: 3.83-22.73). A total of 1723 (47.1%) of healthcare workers declare to be a victim of verbal aggression at work in the last 12 months. The risk of being a victim of verbal aggression at work in the last 12 months is significantly associated with the following independent variables: work in northern Italy (adjusted OR [aOR] 1.54, 95% CI: 1.32-1.81), work in southern Italy (aOR 3.68, 95% CI: 2.90-4.68), and be more than 55 years old (aOR 0.73, 95% CI: 0.63-0.85). CONCLUSIONS: The study underlines that the problem of verbal and physical aggression against healthcare workers is still central and is a further starting point for research. The prevalence of violence is difficult to assess because violent incidents are underreported or unreported. The results of the study suggest that increased awareness is needed to develop effective control strategies at the individual, hospital, and national levels to prevent aggression and improve the conditions of victims.

The Urbino Charter: a Declaration for the well-being of working people.

Abstract: The "Urbino Charter" is a document aimed at promoting the well-being of the working person that the Olympus Observatory of the University of Urbino Carlo Bo and the Rubes Triva National Foundation, a joint body in the field of environmental hygiene, presented in Bilbao at a public conference in March 2023. The Charter has the objective of stimulating reflection on the issues related to prevention while drawing attention to the essential values for the effective protection of workers' health, safety and well-being. This commentary has the aim of presenting the 10 statements of the Chart, from a perspective of Occupational health and safety.

Progesterone and its derivatives for the treatment of catamenial epilepsy: A systematic review.

OBJECTIVE: Catamenial epilepsy (CE) is defined as an increase in seizure frequency during specific phases of the menstrual cycle in women with epilepsy. The treatment usually includes a combination of non-hormonal and hormonal therapies. This systematic review summarizes the available data on the efficacy of progesterone and its derivates to treat CE. METHODS: We performed a systematic search of the literature to identify studies reporting data on the use of progesterone and its derivatives (any type and dose) for the treatment of CE. The main outcome included the efficacy of progesterone and its derivatives on seizure frequency. RESULTS: Nineteen articles (457 patients) were included; four were randomized controlled trials (two comparing progesterone vs placebo and two comparing norethisterone vs placebo). Progesterone was generally administered during the luteal phase (from day 15 to 25) or during perimenstrual exacerbations (from day 23 to 25), with an average dose of 10-30 mg/day to a maximum of 300 mg/day. The therapy, usually well tolerated, was ineffective in the randomized controlled trials; conversely, it was associated with an overall reduction in seizure frequency in case reports and uncontrolled studies. CONCLUSIONS: Although data from uncontrolled studies suggest that hormone therapy with progesterone may be useful in the treatment of CE, its efficacy has not been demonstrated in controlled trials. The possible antiseizure effect of progesterone could be mediated by its active metabolite allopregnanolone, making the plasmatic measurement of these hormones mandatory to evaluate efficacy. Further randomized controlled trials should investigate the efficacy of progesterone and its derivatives, addressing these pharmacological issues.

Transapical beating heart mitral valve repair versus conventional surgery: a propensity-matched study.

OBJECTIVES: Transapical Neochordae implantation (NC) allows beating heart mitral valve repair in patients with degenerative mitral regurgitation. The aim of this single-centre, retrospective study was to compare outcomes of NC versus conventional surgical (CS) mitral valve repair. METHODS: Data of patients who underwent isolated mitral valve repair with NC or CS from January 2010 to December 2018 were collected. A propensity score matching analysis was performed to reduce confounding due to baseline differences between groups. The primary end point was overall all-cause mortality; secondary end points were freedom from reoperation, freedom from moderate (2+) and from severe (3+) mitral regurgitation (MR) and New York Heart Association functional class in the overall population and in patients with isolated P2 prolapse (type A anatomy). RESULTS: Propensity analysis selected 88 matched pairs. There was no 30-day mortality in the 2 groups. Kaplan-Meier analysis showed similar 5-year survival in the 2 groups. Patients undergoing NC showed worse freedom from moderate MR (≥2+) (57.6% vs 84.6%; P < 0.001) and from severe MR (3+) at 5-year follow-up: 78.1% vs 89.7% (P = 0.032). In patients with type A anatomy, freedom from moderate MR and from severe MR was similar between groups (moderate: 63.9% vs 74.6%; P = 0.21; severe: 79.3% vs 79%; P = 0.77 in NC and FS, respectively). Freedom from reoperation was lower in the NC group: 78.9% vs 92% (P = 0.022) but, in type A patients, it was similar: 79.7% and 85% (P = 0.75) in the NC and CS group, respectively. More than 90% of patients of both groups were in New York Heart Association class I and II at follow-up. CONCLUSIONS: Transapical beating-heart mitral chordae implantation can be considered as an alternative treatment to CS, especially in patients with isolated P2 prolapse.

Surface damage to an Oxinium femoral head prosthesis after dislocation.

During open reduction of an irreducible anterior dislocation of a total hip replacement with an Oxinium femoral head, it was observed that the head had been significantly damaged. Gross and scanning electron microscopic examination revealed cracking, gouging, and delamination of the surface. Because of the risk which this poses for damaging the polyethylene acetabular liner, it is strongly recommended that patients with this type of prosthetic head be carefully monitored after a dislocation.

Primary chemotherapy in locally advanced breast cancer (LABC): effects on tumour proliferative activity, bcl-2 expression and the relationship between tumour regression and biological markers.

The rate of tumour cell proliferation evaluated by the [3H]-thymidine labelling index ([3H]-dT-LI) is known to be an independent prognostic factor in patients with operable breast cancer and significantly predicts the response to chemotherapy in patients with advanced disease. In locally advanced breast cancer (LABG), we examined whether chemotherapy induced modifications in [3H]-dt-LI, and bcl-2 expression and their relationship with tumour regression and prognosis. 70 LABC patients received three courses of primary chemotherapy (FEC: 5-fluorouracil 600 mg/m2, epidoxorubicin 60 mg/m2, cyclophosphamide 600 mg/m2, followed by surgery and subsequent adjuvant chemotherapy consisting of three courses of FEC alternated with three courses of CMF (cyclophosphamide 600 mg/m2, methotrexate 40 mg/m2, 5-fluorouracil 600 mg/m2). Tumour biological markers were evaluated on diagnostic biopsy, before primary chemotherapy and at surgery. Tumour cell proliferation was determined by [3H]-dT-LI, whilst bcl-2 expression was examined by immunohistochemical staining. The overall response rate to primary FEC was 74.3% (95% confidence interval 57.6-83.2%). The response rate correlated with high [3H]-dT-LI: 88% (29/33) of patients with high [3H]-dT-LI achieved an objective response compared with 62% (23/37) of patients with low [3H]-dT-LI (P = 0.014). The 3 patients achieving a pathological complete response after induction treatment had high proliferative tumours. The highest 2-year relapse free survival (66.6%) was observed in patients with low [3H]-dT-LI after primary chemotherapy. The median bcl-2 expression values before and after primary chemotherapy were 0% (range 0-80) and 30% (range 0-90), respectively (P = 0.03). Our data indicate that primary chemotherapy can modulate tumour cell kinetics and apoptosis-related genes. Pretreatment proliferative activity correlated with tumour response, whilst post-treatment [3H]-dT-LI correlated with relapse free survival.

The combination of aspiration needle biopsy with fine needle aspiration in the preoperative evaluation of breast tumors.

During a period of 10 years, 2906 women (mostly asymptomatic) were referred to us for physical breast examination. Fine needle aspiration (FNA) was used to examine a nodule or a breast thickening in 860 of these patients. One hundred and ten of these patients also underwent a large needle biopsy (LNB) to add a pre-operative histological evaluation. LNB was performed with 18-20 gauge needles, without cutting the skin and without adding any significant pain or discomfort to that caused by FNA (aspiration needle biopsy, ANB). Diagnostic sensitivity for cancer was 89% for FNA and 100% for ANB. ANB allowed us to correctly identify two cancers with post-operative stage T1N0M-0, which were diagnosed pre-operatively as benign by FNA. The combination of the two needle aspiration techniques (FNA and ANB) allowed us to diagnose 51 of all the 54 cancers (95%). The predictive value of a diagnosis of definite malignancy was 100% for either FNA or ANB. The predictive value of a diagnosis of suspected malignancy showed a predictive value of 72% for FNA and 70% for ANB. Three benign nodules with pre-operative ANB findings of suspected cancer were correctly diagnosed by FNA. Of the 12 cancers with inadequate ANB findings, 11 were correctly diagnosed by FNA. Sixteen of the cancers correctly identified by ANB showed a post-operative size of 2 cm or less (ten cases) or no metastatic axillary lymph-nodes (nine cases).(ABSTRACT TRUNCATED AT 250 WORDS)

Filgrastim and lack of support of intensive adjuvant chemotherapy for high-risk breast cancer patients.

The capacity of filgrastim to reduce the myelotoxicity of a 16-week intensive chemotherapy regimen has been investigated in 24 operable breast cancer patients with > or = 10 metastatic axillary nodes. Five patients were treated with chemotherapy alone (control group); 19 patients were treated with chemotherapy and filgrastim, 5 microg/kg/day s.c. Six patients in the latter group were treated from day 4 to day 7 (level 1), seven from day 10 to day 13 (level 2), and six from day 4 to day 7 and day 10 to day 13 (level 3). A total of 135 courses were administered: neutropenia was the most severe toxicity, and the prophylactic use of filgrastim does not reduce its severity. Moreover, the dose intensities of antiblastic drugs actually received by the patients were not significantly different in the four study groups. Among the patients treated at level 3, there were three toxic deaths: one patient died because of febrile neutropenia and sepsis, two patients because of ischemic colitis. At a median follow-up of 15 months, 17 patients were alive, and 15 patients were disease free. The use of filgrastim does not ameliorate myelotoxicity and does not allow the administration of the planned doses of antiblastic drugs of a 16-week intensive chemotherapy regimen.

Relationship between progesterone receptor and productive fibrosis as an index of tumor differentiation in breast cancer.

We studied the relationship between steroid receptors (SR) and various stromal parameters in 100 breast cancers. Each specimen was submitted to SR determination by the dextran-coated charcoal assay and to histologic examination. No relationship was found between the presence of SR and necrosis or fibroblastic cell content. There was an inverse correlation between SR positivity and the extent of lymphocyte infiltration (p less than 0.05). ER + PR + status was strongly correlated with marked productive fibrosis (PF) (p less than 0.005). When SR were separately assayed, only the presence of PR was correlated with PF (p less than 0.005); similar results were obtained for PR levels (p less than 0.01). PF was also associated with a higher nuclear grade (p less than 0.001). In conclusion, in this study a strong correlation between PR positivity or concentration and extent of PF was demonstrated in breast cancer. Since PR synthesis is an expression of an intact regulatory pathway, our data suggest that stromal production in breast cancer is related to the degree of differentiation of malignant epithelial cells.

Anti-ulcer drugs and hypergastrinism: utilization in surgery.

The peptic ulcer disease associated with hypergastrinemia is very often a challenging problem of diagnosis and therapy. In absolute surgical emergency (haemorrhagic and perforative complications), the utilization of the most recently discovered anti-ulcer drugs appears to be extremely helpful; the prevention of incumbent complications can be accomplished, in fact, during the post-operative treatment and the "free time" so obtained can be used for an adequate differential diagnosis (gastrinoma-induced Zollinger-Ellison syndrome: antrum retained, G cells of the antrum hyperplastic, apud-tumours with hypersecretion). The "anti-H2 and anti-muscarinic" drugs (often in association) give the surgeon the possibility of an accurate diagnosis and the choice of the best surgical procedure (tumorectomy, DCP, gastrectomy). Even in elective surgery the prevention with anti-H2 drugs permits greater "safety margins" and an optimal follow-up study. The results of the surgical experience in the General Surgical Clinic of Pisa (18 cases of Z.E.'s) confirm the validity of the associated anti-ulcer therapy.

[A 1st experience with radical surgery of cancer of the rectum. Critical analysis of the literature and case reports, with special reference to methods "of security" and to technical guidelines for reducing complications and mortality]. / Una prima esperienza di chirurgia radicale per cancro del retto. Analisi critica della letteratura e della casistica, con particolare riferimento alla metodologia "di sicurezza" e alla impostazione tecnica per ridurre complicanze e mortalità.

An analysis of the most recent approaches to oncological surgery of the rectum, with particular reference to methods combining the greatest radicality with the lowest incidence of early and late complications, is followed by the presentation of work carried out over a period of four years at a subsidiary university department. A series of 77 radical operations (50 anterior and 27 abdominoperineal resections) is examined in function of the pre-, intra-, and postoperative measures making up the treatment protocol. The results are in line with the currently growing preference for anterior resection, and underscore the effectiveness of excluding right colostomy as a protective measure in low colorectal anastomosis. An absence of p.o. mortality a low incidence of complications significant with regard to short and long survival, and the data obtained from a short follow-up show that the methods are sound and in line with the more extensive university series, as well as the data in the literature

Dyspareunia associated with a pelvic digit.

A pelvic digit is a rare congenital anomaly and often an incidental radiographic finding. Here we present the first reported case of a 57-year-old Caucasian female with a pelvic digit and a chief complaint of dyspareunia. Radiographic studies and magnetic resonance imaging confirmed a stable bony excrescence from the inferior left ischium impinging on the pelvic floor. The patient underwent surgical removal of the pelvic digit without complications. Accurate diagnosis of pelvic lesions is necessary to guide treatment.

Molecular and functional characterization of polynucleotide phosphorylase from the antarctic eubacterium Pseudoalteromonas haloplanktis.

Polyribonucleotide phosphorilase from the psychrophilic Antarctic eubacterium Pseudoalteromonas haloplanktis (PhPNPase) has been purified. This enzyme catalyzes both the RNA polymerisation and degradation reaction, showing the highest activity at temperatures below 40 degrees C. PhPNPase is quite sensitive to heat treatment and it is endowed with remarkable halotolerance.

Perineal colostomy and electrostimulated gracilis "neosphincter" after abdomino-perineal resection of the colon and anorectum: a surgical experience and follow-up study in 47 cases.

A series of 47 patients undergoing abdomino-perineal resection of the distal colon and anorectum and construction of a continent perineal colostomy using electrostimulated gracilis muscle is described. External and implanted pulse generators have both been used. An analysis of complications and oncological data are reported. There was no operative mortality. The incidence of complications, divided into three classes, mild (62%), moderate (27%) and severe (11%), has not significantly altered the functional results, with the exception of early ischaemia of the colonic stump in two cases. During the first 22 cases, no preoperative oncological staging was performed. In the last 23 patients endorectal ultrasonography and CT scanning were carried out. Functional results were evaluated by electromanometry, electromyostimulation and dynamic defaecography. Clinical data assessed postoperatively showed good function in 65% of cases, fair in 22.5% and poor in 12.5%. The quality of life in 15 patients with a perineal colostomy and electrostimulated gracilis was significantly better than in 15 patients having an abdomino-perineal resection without gracilis plastic reconstruction.

Relationship between progesterone receptor, axillary node status and productive fibrosis in ductal infiltrating carcinoma of the breast.

The presence of progesterone receptor (PR), productive fibrosis (PF), axillary nodal status and tumor size are important prognostic variables in breast cancer. In this study we have analyzed the relationship between these four parameters in 78 ductal infiltrating carcinomas of the breast. No relationship was found between PF and the presence of lymph node metastatic disease: however, in the tumors with positive nodes, a limited metastatic diffusion (1-3 lymph nodes) was significantly associated with PF (p less than 0.05). Our study failed to demonstrate any relation between estrogen receptor (ER) and both presence and extension of nodal involvement; in contrast, the tumors with limited metastatic diffusion (1-3 lymph nodes) had a significantly higher prevalence of PR positivity (p less than 0.05). Furthermore, PF was strongly associated with PR (p less than 0.001) and less well with ER (p less than 0.05). The simultaneous presence of PR and marked PF was strongly correlated with limited metastatic involvement of the axilla (p less than 0.007). Tumor size was correlated with the number of positive nodes (p less than 0.001), but not with PR or PF. The results demonstrate that PR status, PF and tumor size are related to limited metastatic diffusion of the axilla: furthermore PF and PR have been shown to be strongly related and we have demonstrated that, at least in ductal infiltrating carcinoma, the simultaneous presence of them identifies a subset of tumors with low metastatic capacity independently of tumor size.

Construction of a continent perineal colostomy by using electrostimulated gracilis muscles after abdominoperineal resection: personal technique and experience with 32 cases.

A series of 32 patients operated on for rectal carcinoma is reported. A new technique by using the gracilis muscles to reconstruct a functional anal sphincter after abdominoperineal resection was performed. No operative mortality was recorded. Functionality of the new sphincter was guaranteed by electromyostimulation. Electrostimulation has been useful in both increasing the muscular trophic level and in improving the postoperative bio-feedback. Perineal infection was recorded in 9 patients being the most common complication although it did not compromise the functionality of the new sphincter. In one case acute colonic ischaemia was treated by resection and definitive left colostomy. 17 out of the 27 patients in which a functional follow-up was obtained, scored a "very good" continence to stool and flatus while in 6 patients occasional episodes of incontinence to liquid stool are referred. Local or distant metastases presented in 6 patients. The obtained results encourage in continuing the research with this technique in the attempt to reduce the number of patients that must pay the high price of a definitive abdominal colostomy for cure.

Accelerated versus standard cyclophosphamide, epirubicin and 5-fluorouracil or cyclophosphamide, methotrexate and 5-fluorouracil: a randomized phase III trial in locally advanced breast cancer.

BACKGROUND: The purpose of this study was to evaluate the impact of a dose-dense primary chemotherapy on pathological response rate (pCR) in patients with locally advanced breast cancer (LABC) treated with combined modality therapy. PATIENTS AND METHODS: Stage IIIA/IIIB patients received three courses of induction chemotherapy (ICT) with cyclophosphamide, epirubicin and 5-fluorouracil (CEF) followed by local therapy (total mastectomy or segmental mastectomy with axillary nodes dissection) and adjuvant chemotherapy (ACT) with three courses of CEF alternated with three courses of cyclophosphamide, methotrexate, 5-fluorouracil (CMF). Patients were randomized to receive ICT and ACT every 3 weeks (arm A, 'standard treatment') or every 2 weeks with granulocyte-macrophage colony-stimulating factor (GM-CSF) support (arm B, 'dose-dense treatment'). In both arms radiotherapy was administered after the end of chemotherapy (in selected cases) and patients with hormonal receptor-positive tumors received tamoxifen for 5 years. RESULTS: A total of 150 patients were randomized (77 arm A and 73 arm B) and demographics were well balanced between the two arms. Compliance to treatment was excellent: 95% and 93% of patients in arms A and B, respectively, completed the treatment program with no modification or delay. Median duration of treatment (ICT+local+ACT) was 183 days (range 0-265) in arm A and 139 days (0-226) in arm B. The average relative dose intensity (ARDI) of chemotherapy was 1.3 with a 30% increase in the dose intensity in arm B in comparison with arm A. No difference in clinical [62%; 95% confidence interval (CI) 49% to 73.2%] and pathological response rates to ICT was observed between the two arms. Median follow-up was 5 years (range 1-96 months); median disease-free survivals were 4.8 years in arm A and 4.5 years in arm B. Median overall survival was 7.8 years in standard therapy: this figure has not yet been reached in the dose-dense treatment. CONCLUSIONS: In LABC a dose-dense regimen, while allowing a 30% increase in the dose intensity of chemotherapy, did not provide significant improvement in pathological response rates. However, accelerated chemotherapy reduced the duration of the combined-modality program (6.1 versus 4.6 months) with no additional toxicities.
