ABSTRACT

OBJECTIVE: The primary aim of this article was to describe SARS-CoV-2 infection among pregnant women during the wild-type and Alpha-variant periods in Italy. The secondary aim was to compare the impact of the virus variants on the severity of maternal and perinatal outcomes. DESIGN: National population-based prospective cohort study. SETTING: A total of 315 Italian maternity hospitals. SAMPLE: A cohort of 3306 women with SARS-CoV-2 infection confirmed within 7 days of hospital admission. METHODS: Cases were prospectively reported by trained clinicians for each participating maternity unit. Data were described by univariate and multivariate analyses. MAIN OUTCOME MEASURES: COVID-19 pneumonia, ventilatory support, intensive care unit (ICU) admission, mode of delivery, preterm birth, stillbirth, and maternal and neonatal mortality. RESULTS: We found that 64.3% of the cohort was asymptomatic, 12.8% developed COVID-19 pneumonia and 3.3% required ventilatory support and/or ICU admission. Maternal age of 30-34 years (OR 1.43, 95% CI 1.09-1.87) and ≥35 years (OR 1.62, 95% CI 1.23-2.13), citizenship of countries with high migration pressure (OR 1.75, 95% CI 1.36-2.25), previous comorbidities (OR 1.49, 95% CI 1.13-1.98) and obesity (OR 1.72, 95% CI 1.29-2.27) were all associated with a higher occurrence of pneumonia. The preterm birth rate was 11.1%. In comparison with the pre-pandemic period, stillbirths and maternal and neonatal deaths remained stable. The need for ventilatory support and/or ICU admission among women with pneumonia increased during the Alpha-variant period compared with the wild-type period (OR 3.24, 95% CI 1.99-5.28). CONCLUSIONS: Our results are consistent with a low risk of severe COVID-19 disease among pregnant women and with rare adverse perinatal outcomes. During the Alpha-variant period there was a significant increase of severe COVID-19 illness. Further research is needed to describe the impact of different SARS-CoV-2 viral strains on maternal and perinatal outcomes.

ABSTRACT

BACKGROUND: Among asylum seekers and refugees in European countries, several studies have shown a high burden of mental disorders, including post-traumatic stress disorder, anxiety, depression and psychoses. The present study compares hospitalization for mental disorders among migrants arriving from countries typically linked to the refugee phenomenon (putative asylum seekers), migrants arriving from other countries, and natives. METHODS: The study is based on hospital discharge data collected at the national level by the Italian Ministry of Health. Age-standardized hospitalization rates for mental health diagnoses are calculated for the three groups during the period 2008-2015. Differences in type of admission (urgent or planned) and length of stay in hospital are also assessed. RESULTS: Temporal trends show a general decrease of hospitalization rates for mental disorders among both immigrants and natives; however, an increase is observed among young male putative asylum seekers (from 30.3 in 2010 to 43.6 per 10,000 in 2015), mainly due to admissions for "other nonorganic psychoses". CONCLUSION: These findings suggest that in Italy a higher burden of mental disorders might derive from the landing phenomenon, and the increase of hospitalization ascribed to "other nonorganic psychoses" (which is a general and unspecific diagnostic label) might conceal diagnostic difficulties by Italian psychiatrists to recognize atypical pictures associated with traumatic experiences.

ABSTRACT

BACKGROUND: Discrimination at the workplace can be considered a risk factor for immigrants' health. OBJECTIVES: In this study we compared the occurrence of episodes of arrogance or discrimination perceived at the workplace between documented immigrants coming from countries with high migration pressure and Italians, and evaluated the role of selected risk factors among immigrants. METHODS: Using data from the 2007 Labour Force Survey conducted by the Italian National Institute of Statistics, adjusted odds ratios (ORs) for socio-demographic and occupational variables were estimated among a nationally representative sample of 61,214 employed persons aged 15 years or more. RESULTS: The occurrence of perceived arrogance or discrimination was higher among immigrant compared to Italian males for all geographical areas of origin considered. Adjusted ORs were 4.6 (95% CI: 3.6-5.8) for Africans, 3.4 (95% CI: 2.5-4.6) for Asians, 2.1 (95% CI :1.6-2.8) for Eastern Europeans, and 2.0 (95% CI: 1.0-3.7) for Latin Americans. Among male immigrants a higher occurrence of arrogance or discrimination was found for construction and other industrial workers and for those residing in central-southern regions of Italy. Among female workers only Latin Americans and Africans showed a higher occurrence of perceived arrogance or discrimination compared to Italians: adjusted ORs were respectively 3.9 (95% CI: 2.6-5.7) and 2.6 (95% CI:1.5-4.5). Female immigrants with a medium-to-high level of education or a highly skilled job, and those residing in the central-southern regions of ltaly perceived the highest occurrence of arrogance or discrimination. CONCLUSIONS: The study highlighted the need for policies to protect the wellbeing of immigrants that seem to be particularly exposed to patterns of discrimination at the workplace.

ABSTRACT

BACKGROUND AND AIMS: Caecal intubation fails up to 20% of colonoscopy in clinical practice. We aimed to assess whether (1) in patients with a prior incomplete colonoscopy with a standard adult colonoscope, a subsequent caecal intubation may be achieved with the same instrument; (2) there are factors predicting a repeated unsuccessful colonoscopy; and (3) how frequently completion can be further achieved by shifting to a standard gastroscope. MATERIALS AND METHODS: Data of patients with a previously failed bowel examination referred to our community hospital for a further colonoscopy were reviewed. When caecal intubation still failed with standard colonoscope, complete colonoscopy was usually attempted by shifting to a gastroscope. RESULTS: Overall, 451 patients with a prior colonoscopy were considered. By using a standard colonoscope, caecal intubation rate was achieved in 285 out of 296 patients with prior complete examination and in 121 out of 155 patients with a prior failed colonoscopy (96.3% vs. 78.1%, p < .001). Caecum visualization was significantly lower when prior colonoscopy was stopped in the sigmoid tract as compared to any other proximal tract (65.1% vs. 86.9%, p < .001). After a second failed examination, colonoscopy was completed in 15 (51.7%) out of 29 cases by shifting to a standard gastroscope. No procedure-related complications were observed in the study. CONCLUSIONS: After incomplete colonoscopy with a standard adult colonoscope, a further colonoscopy may be completed with same standard colonoscope or by using a gastroscope in the same session. A prior failed colonoscopy, particularly when stopped in the sigmoid tract, is significantly associated with a lower caecal intubation rate at second colonoscopy.

ABSTRACT

BACKGROUND AND AIMS: Issues on colonoscopy quality are crucial to reduce the advanced neoplasia miss rate of colonoscopy. Recently, a >6-min withdrawal time has been recommended. However, the relative prevalence of polyp detected during insertion and withdrawal phases of colonoscopy is unknown. Therefore, we designed this prospective, endoscopic study. MATERIALS AND METHODS: Three hundred and sixty-eight patients with 396 adenomas were selected from a consecutive colonoscopic series of 1,205 cases. Detection rates of adenomas, advanced adenomas, and cancer according to withdrawal and insertion phases of colonoscopy, also subgrouping polyps for size and location, were compared. RESULTS: Thirty-two (74%) advanced adenomas and 21 (95%) cancers were detected during the insertion, being only 11 (26%) and one (5%) identified during withdrawal, respectively. This was mainly due to a higher detection of >10 mm polyps during insertion than during withdrawal (75% versus 25%). CONCLUSIONS: Most advanced neoplasia are detected during the insertion. Although withdrawal time has been shown to be important, the scope insertion phase related to polyp detection should be specifically addressed.

ABSTRACT

The prevalence of diverticulosis and colorectal cancer (CRC) is markedly increased in the last century. Both diseases are highly frequent in Western countries and in aged people. Western diet--low in fiber and rich in dietary fat--has been largely regarded to play a major role in the pathogenesis of both conditions. A causal relationship between diverticulosis and CRC has been suggested in different studies. Epidemiologic series found a more frequent rectosigmoid localization of neoplastic lesions (advanced adenoma and CRC) in patients with diverticulosis as compared with controls, particularly in those with a previous diverticulitis episode or with an extensive disease. However, data are still controversial, with other studies failing to confirm this observation. Such discrepancy could be referred to the highly heterogeneous study design and setting in the different epidemiologic series. Pathologic studies showed that either macroscopic and microscopic chronic inflammation--which is regarded as risk factor for CRC development--is present in the colonic mucosa of some patients with diverticula. Moreover, alterations in the extracellular matrix, also involved in colorectal carcinogenesis, have been depicted in diverticulosis. In addition, an upward shifting of cell proliferation occurs in diverticular mucosa, and in nondiverticular patients with advanced adenomas. Finally, aberrant crypt foci--which are considered potential markers of CRC risk in ulcerative colitis--have been detected in colonic mucosa of patients with diverticulosis. Despite this substantial amount of evidence, however, the available data are not yet strong enough to suggest a more aggressive CRC prevention in diverticular as compared with nondiverticular subjects.

ABSTRACT

Peptic ulcer bleeding is a frequent and dramatic event with both a high mortality rate and a substantial cost for healthcare systems worldwide. It has been found that age is an independent predisposing factor for gastrointestinal bleeding, with the risk increasing significantly in individuals aged>65 years and increasing further in those aged>75 years. Indeed, bleeding incidence and mortality are distinctly higher in elderly patients, especially in those with co-morbidities. NSAID therapy and Helicobacter pylori infection are the most prevalent aetiopathogenetic factors involved in peptic ulcer bleeding. The risk of bleeding seems to be higher for NSAID- than for H. pylori-related ulcers, most likely because the antiplatelet action of NSAIDs impairs the clotting process. NSAID users may be classified as low or high risk, according to the absence or presence of one or more of the following factors associated with an increased risk of bleeding: co-morbidities; corticosteroid or anticoagulant co-therapy; previous dyspepsia, peptic ulcer or ulcer bleeding; and alcohol consumption. Different types of NSAIDs have been associated with different bleeding risk, but no anti-inflammatory drug, including selective cyclo-oxygenase (COX)-2 inhibitors, is completely safe for the stomach. Furthermore, even low-dose aspirin (acetylsalicylic acid) [<325 mg/day] and a standard dose of non-aspirin antiplatelet treatment (clopidogrel or ticlopidine) have been found to cause bleeding and mortality. No clear risk factor favouring H. pylori-related ulcer bleeding has been identified. Peptic ulcer bleeding prevention remains a challenge for the physician, but data are now available on use of a safer and cheaper strategy for both low- and high-risk patients. Unfortunately, despite the fact that several society and national guidelines have been formulated, these are poorly followed in clinical practice. Proton pump inhibitor (PPI) or misoprostol therapy and H. pylori eradication in NSAID-naive patients are the most commonly proposed strategies. Selective COX-2 inhibitor therapy in high-risk patients has also been suggested, but concerns over the possible cardiovascular adverse effects of some of these agents should be taken into account. Moreover, switching to selective COX-2 inhibitors in patients with previous bleeding is not completely risk free, and concomitant PPI therapy is also needed. H. pylori eradication is mandatory in all patients with peptic ulcer, and such an approach has been found to be significantly superior to PPI maintenance therapy. H. pylori eradication is frequently achieved with sequential therapy in elderly patients with peptic ulcer. In conclusion, upper gastrointestinal bleeding is a dramatic event with a high mortality rate, particularly in the elderly. Some effective preventative strategies are now available that should be implemented in clinical practice.

ABSTRACT

Abnormalities in the interactions of cells with the extracellular matrix (ECM) play an important role in the development and progression of many types of cancer and are a hallmark of malignant transformation. The dystroglycan (DG) complex is a transmembrane glycoprotein that forms a continuous link from the ECM to the actin cytoskeleton, providing structural integrity and perhaps transducing signal, in a manner similar to integrins. Deregulated expression of DG has been reported in a variety of human malignancies and related to tumor differentiation and aggressiveness. In breast cancer, reduced DG expression has been associated with patient survival and with loss of differentiation of tumor cells. Limited data are available on DG physiology in epithelial cells. In this study, we used the HC11 spontaneously immortalized murine mammary epithelial cells to study DG function(s) and regulation in normal cells. We found that expression of DG protein and mRNA is cell-cycle and cell-density regulated in these cells. Moreover, expression of both DG subunits increased upon lactogenic differentiation of the HC11 cells. The turnover of cell-surface-expressed DG was evaluated in the same cells and half-life of DG subunits was evaluated to be about 12 h. DG-specific small inhibitory RNAs were used to analyze the effects of a reduced expression of DG in these cells. Cells in which DG expression was suppressed were growth inhibited, accumulated in the S-phase of the cell cycle, failed to undergo lactogenic differentiation, and displayed an increase in the percentage of apoptotic cells. Moreover, changes were observed in the expression and/or activity of several molecules involved in cell growth control. These results demonstrate that DG expression is tightly regulated in normal mammary epithelial cells and support the hypothesis that DG is involved in several functions other than structural integrity in these cells. This finding provides new insight into the roles played by DG in epithelial cell physiology and will contribute to our understanding of its involvement in the process of epithelial cell transformation.

ABSTRACT

During the past ten years we have seen two or more episodes of erythema nodosum develop in five patients in association with either pregnancy or the ingestion of female hormones. No alternative causes of erythema nodosum were found in these patients. The occurrence of erythema nodosum in association with hormonal change suggests that female hormones can, under some circumstances, be directly responsible for development of the disease.

ABSTRACT

The report presents evidence of the transmission of hpv-77 derived rubella vaccine virus from vaccinees to two susceptible contacts. The first instance of transmission was to a child who served as a transmission control on a "closed" study ward, and the second was to an antibody-negative mother in an "open" family study. Neither of these persons had any clinical evidence of rubella. Both had significant increases in rubella hemagglutination inhibiting (hai) antibody titers, but detectable complement fixing (cf) antibodies did not develop in either. With the kind of antigen used in our rubella cf test, this pattern of serologic response is characteristic of, but not diagnostic of, infection with the rubella vaccine virus. The serological evidence which was compatible with rubella vaccine virus infection, the complete absence of serologic or clinical evidence of "wild" rubella virus infections among the other four rubella susceptible transmission control children and the security precautions employed to ensure isolation on the "closed" ward, make "wild" rubella virus infection extremely unlikely. The evidence for rubella vaccine virus infection in the other susceptible contact is not as conclusive, because "wild" rubella virus infection is difficult to rule out in any person living in an "open" family situation. Nevertheless the need for more data is emphasized by the virtual certainty that rubella vaccine virus transmission did occur in the subject on the isolation ward, plus the high probability that the infection observed in the family group setting also represented transmission of rubella vaccine virus. Such data can only come from close surveillance of recipients of live rubella virus vaccines and their contacts in the future.

ABSTRACT

Q fever is endemic and enzootic in Los Angeles County. A serological survey conducted in 1949 is compared with a current survey. Infection in dairy herds is now almost universal, while the prevalence of positive complement fixation titers in man only increased from 1.2 percent to 2.3 percent (p <0.10). The relative stability in man is accounted for by the increase in temperature requirements for milk pasteurization, the decrease in consumption of raw milk and the decrease in the number of dairy farm foci.
