The cesarean section is utilized to deliver babies since the late 19th century. Nowadays, the frequency of cesarean section is increased, mainly because of the low rate of complications and for the increasing demand from future mothers, scared by the idea of painful labor. Although the technique to perform cesarean section has been refined over time, infections, hemorrhage, pain and other consequences still represent matter of debate. To try to reduce the incidence of these complications many trials, randomized or not, have been performed, with the aim to analyze different technical aspects of this surgery. The aim of our review was to resume all the evidence-based instructions on how to best approach to cesarean section practice, in a step-to-step fashion, considering pre-operative actions, opening and closing steps, and postoperative prophylaxis.
The Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is a new coronavirus detected in China at the end of 2019. Because SARS-CoV-2 is highly infectious due to contamination in the air, there is a high risk of infection in the dental environment which is represents a serious problem for professionals and students (dentistry and dental hygiene). In Italy, since February 23, 2020, the government has suspended all teaching activities of schools and universities.

An anonymous questionnaire was administered to the students of the degree courses in Dental Hygiene of the Emilia Romagna Region, one of the most affected regions in Italy. The survey was intended to highlight the practical and emotional consequences of the emergency of COVID-19 on educational activities and in the training of students.

The survey was sent to the 150 students enrolled in the universities of Bologna, Ferrara and Modena and Reggio Emilia; 141 of them completed it (94%). Since the start of the COVID-19 pandemic, several surveys have been proposed to measure the impact of this emergency situation on dental professionals; at present, however, there are still no assessments for dental hygiene degree courses, in particular aimed at assessing the psychological impact on students.

Students consider the dental hygienist as a risky profession, while the risk taken by patients is considered as low. Given the concern reported the students, it would be useful to address the issue of proper assessment of risk during the university training of dental hygienists.

Psoriasis is a chronic inflammation resulting from interactions between immunological and genetic factors. selleck inhibitor An important tolerogenic role in this autoimmunological disease is played by HLA-G, which is modulated by IL-10. Therefore, this study (N=80) aimed to evaluate changes in the serum sHLA-G and IL-10 levels in active psoriasis vulgaris and in the early stages of treatment with Methotrexate (MTX) compared to healthy controls. The 14-bp INDEL of the HLA-G gene was evaluated to find possible associations with clinical and laboratory variables.

The level of sHLA-G and IL-10 in serum was evaluated (ELISA tests) in patients before the first dose of MTX and at week 12 of treatment, compared to healthy control donors. The 14-bp INDEL in 3'UTR of the HLA-G gene was identified using gDNA templates isolated from full blood. HLA-G amplicons were obtained by PCR, separated by electrophoresis and sequenced.

The mean serum IL-10 level was 4.653 ±3.33 pg/mL in psoriatic patients, 13.3 ± 9.64 pg/mL after short MTX trlance function.
The mean levels of sHLA-G and the key anti-inflammatory cytokine IL-10 in the blood of pre-treatment psoriasis patients are low and indicate that the immunotolerance mechanisms have failed. Treatment of psoriasis patients with low systemic levels of sHLA-G and IL-10 brings them to the same or higher protein levels, respectively, as in healthy donors. Higher sHLA-G levels in healthy donors and after MTX treatment, compared to the sHLA-G levels in the acute phase of psoriasis, indicates its immune system surveillance function.
To investigate the role and underlying mechanism of miR-4497 in oxidative stress and inflammatory injury in keratinocytes induced by ultraviolet B (UVB) radiation.

An injury model of keratinocytes induced by UVB radiation was constructed. RT-qPCR, MTT assay and flow cytometry were adopted to detect miR-4497 expression in HaCaT cells, cell proliferation, and cell apoptosis, respectively. The levels of cytokines TNF-α, IL-18, IL-6 and IL-1β in cell culture supernatant were tested by ELISA. ROS levels in the cells were labeled by DCFH-DA fluorescent probe, and then quantitative fluorescence analysis was performed by flow cytometry. SOD activity in the cells was measured by Xanthine Oxidase assay kit. Western blot was used to determine NF-κB expression in cytoplasm and nucleus, and p-IκBα expression in the cells.

UVB radiation significantly increased miR-4497 expression in HaCaT cells, inhibited cell proliferation, and promoted cell apoptosis. Meanwhile, UVB radiation caused the promotion of secretion of cytokines TNF-α, IL-18, IL-6 and IL-1β. The production of reactive oxygen species (ROS) was promoted by UVB radiation, while SOD activity was inhibited. Nuclear transfer of NF-κB signal was also induced by UVB radiation. In addition, downregulation of miR-4497 expression significantly inhibited the effects of UVB radiation on cell proliferation, apoptosis, cytokine secretion, redox level and NF-κB signal in HaCaT cells, while overexpression of miR-4497 further enhanced these effects of UVB radiation on HaCaT cells.

UVB may promote the expression of inflammatory and oxidative stress signals in keratinocytes by upregulating miR-4497 expression, thus mediating cell injury.

Sexually transmitted infections (STIs) may impact on the patient's physical, psychological and sexual health and negatively influence their quality of life (QOL). Studies on this topic are scarce. This study aimed to assess the impact of STIs different from HIV on QOL, mood and sexual functioning in the patients attending our STIs center in comparison with patients affected by chronic inflammatory bowel diseases (IBD).

An anonymous questionnaire was provided. It included 3 validated questionnaires the European Quality of Life 5 dimensions 5 levels; the Beck Depression Inventory-II for depressive symptoms; the Changes in Sexual Functioning Questionnaire (CSFQ) for sexual functioning.

Seventy-three STIs patients and 51 IBD patients partecipated in the study. The mean EQ-5D-5L questionnaire scores were 86.72 in STIs and 89.21 in IBD patients, without statistically significant difference between the two groups. Symptoms of depression were more common and severe in STIs patients compared to IBD patients. Sexual functioning was slightly worse in STIs patients than in IBD patients.
