Does Hormone Replacement Therapy Impact the Prognosis in Endometrial Cancer Survivors? A Systematic Review.

PURPOSE: The objective of this study was to evaluate the impact of hormone replacement therapy (HRT) on the prognosis in endometrial cancer (EC) survivors. METHODS: The research was conducted using the following electronic databases: MEDLINE (PubMed), Web of Science, ClinicalTrial.gov, and Cochrane Library. We performed a review of studies published from January 1986 to January 2019. We selected studies that included EC patients submitted to surgery with curative intent and postoperative use of HRT. RESULT: Seven of 1,332 abstracts considered were eligible: 4 retrospective series, 1 prospective study, 1 randomized controlled trial, and 1 population study. Globally in the observed studies there was not a significant increase in the recurrence rate, measured by the relative risk, in the EC survivors using HRT compared with the controls in tumour stages I and II. The bias was that HRT was prescribed only to low-risk patients, who were young and had a low stage of disease. CONCLUSION: This systematic review shows that HRT use had no negative effect on prognosis in EC survivors in tumour stages I and II.

Is BRCA mutational status a predictor of platinum-based chemotherapy related hematologic toxicity in high-grade serous ovarian cancer patients?

OBJECTIVE: To evaluate hematologic adverse effect profiles associated with frontline platinum-based chemotherapy in ovarian cancer patients according to BRCA 1/2 mutational status. METHODS: Patients with high-grade serous ovarian cancer and a known BRCA mutational status who received in frontline 6 cycles of Carboplatin (AUC 5) plus Paclitaxel 175 mg/mq were retrospectively selected from our databases. Hematologic toxicity profiles of BRCA mutated patients were compared to non-mutated patients, according to EORTC Common Terminology Criteria for Adverse Events (CTCAE_4.02). RESULTS: Totally, 176 women of whom 58 (33%) were BRCA1/2 mutation carriers - 40 BRCA1 (69%) and 18 (31%) BRCA2 mutations carriers - and 118 (67%) non-carriers were identified. A significant higher frequency of thrombocytopenia (24% vs 5%; p < 0.001), anemia (21% vs 7%; p = 0.006) and neutropenia (62% vs 27%; p ≤0.001) was observed in BRCA mutated patients, resulting in a higher percentage of granulocyte-colony stimulating growth factors injection (12% versus 1%, p < 0.001) and dose delay (19% versus 27%, p = 0.005). The multivariate analysis confirmed that granulocyte-colony stimulating growth factors injection and dose delay were statistically significantly more frequent in BRCA mutated patients (OR 2.567, 95% CI 1.136-5.798, p = 0.035; OR 3.860, 95% CI 1.098-13.570, p = 0.023). Finally, the total number of hematologic adverse events compared between the two groups of patients during the entire treatment period showed a substantial higher rate of hematologic adverse events in BRCA mutated population. CONCLUSIONS: Germline BRCA 1/2 mutations are associated with a higher hematologic toxicity in patients with ovarian cancer who underwent platinum-based chemotherapy.

Do social media interventions increase vaccine uptake?

Introduction: The Italian mass COVID-19 vaccination campaign has included children aged 5-11 years as part of the target population since December 2021. One of the biggest challenges to vaccine uptake was vaccine hesitancy among parents and children's caregivers. Primary care pediatricians (PCPs), as the first point of contact between the National Health Service (NHS) and parents/caretakers, initiated various communication strategies to tackle this hesitancy. This study aims to evaluate the impact of a PCP-led social media intervention and a digital reminder service (DRS) on parental hesitancy regarding vaccinating their 5-11-year-old children against COVID-19. Methods: A prospective cohort study was designed, and the chosen target populations were parents and caretakers of children aged 5-11 years. Two PCP cohorts were recruited. The first group received a social media intervention and a DRS; while the second group did not. Both cohorts had access to traditional face-to-face and telephone-based counseling. The vaccination coverage rate in the two groups was evaluated. Results: A total of 600 children were enrolled. The exposed cohort (277 patients) received social media intervention, DRS, and counseling options (face-to-face and telephone-based), whereas the non-exposed cohort (323 patients) received only counseling options. In total, 89 patients from the exposed cohort did not receive any dose of the COVID-19 vaccine (32.5%), 165 were fully immunized (59.5%), and 23 received only one dose (8.5%). A total of 150 non-exposed patients did not receive any dose of the COVID-19 vaccine (47%), 147 were fully immunized (45.5%), and 24 only received one dose (7.4%). The difference between the two groups was statistically significant (chi square = 11.5016; p = 0.0006). Conclusion: Social media and DRS interventions had a positive impact on vaccine uptake and may be helpful in tackling vaccine hesitancy. Better-designed studies are needed to corroborate these findings.

Social Media Interventions Strengthened COVID-19 Immunization Campaign.

Background: Since The Italian Medicines Agency (AIFA) has recommended the COVID-19 vaccine Comirnaty in children aged 5-11, the immunization campaign faced vaccine hesitancy in parents. Social media are emerging as leading information source that could play a significant role to counteract vaccine hesitancy, influencing parents' opinions and perceptions. Our aim was to evaluate the coverage of the COVID-19 vaccine Comirnaty in a cohort of children aged 5-11 whose families have been counseled to use Social Media to counteract vaccine hesitancy. Methods: All parents of children aged 5-11 in a primary care setting were instructed by their pediatrician to get accurate information about the COVID-19 vaccine from a Facebook page. Active calls to vaccinate children were also scheduled through messaging services Pediatotem and Whatsapp. Vaccination rates of children in the study were assessed with an electronic database and compared to both regional and national child vaccination rates. Results: Coverage of 277 children aged 5-11 was analyzed from 16 December 2021 to 31 January 2022. A total of 62.4% (173/277) of enrolled children received the 1st dose of COVID-19 vaccine Comirnaty and 39.7% (110/277) the 2nd dose. Coverage rates were higher compared both to the regional population (1st dose: 48.8%, 2nd dose: 24.6%; p = 0.001) and national population (1st dose: 32.1%, 2nd dose: 13.8%; p < 0.001). Conclusion: Increasing vaccine confidence using Social Media interventions have a positive impact on vaccination acceptance of parents.

In-hospital and web-based intervention to counteract vaccine hesitancy in very preterm infants' families: a NICU experience.

BACKGROUND: Vaccine hesitancy is a global problem, carrying significant health risks for extremely vulnerable population as that of preterm infants. Social media are emerging as significant tools for public health promotion. Our aim was to evaluate both the coverage and the timeliness of routine immunizations in a cohort of preterm infants (< 33 weeks of gestational age) at 24 months of age whose families have been subjected to in-hospital and web-based interventions to counteract vaccine hesitancy. METHODS: For a period of 2 years parents of preterm infants were instructed during their follow up visits by a member of the NICU team to get correct informations about vaccines from a social network page. Vaccination rates of preterm infants were assessed at 24 months of chronological age with an electronic database and compared to both general population and historical cohort. RESULTS: Coverage and timeliness of vaccinations at 24 months of age of 170 preterm infants were analyzed in December 2019. Gestational age and birth weight median (IQR) were, respectively, 31.0 (5.0) weeks and 1475.0 (843.8) g. Coverage rates were similar to those of the regional population (p > 0.05), while timeliness of administration was significantly delayed compared to the recommended schedule (p < 0.001). Age of administration was not correlated with either body weight and gestational age at birth (Spearman rank, p > 0.05). DTaP-IPV-HBV-Hib 2nd and 3rd doses, MMR and Varicella vaccines coverage data were higher compared to historical cohort (p < 0.05). CONCLUSION: Increasing vaccine confidence through web-based interventions could have a positive impact on vaccination acceptance of parents of preterm infants, although timeliness results still delayed. There is a strong need to develop different and effective vaccination strategies to protect this very vulnerable population.

Management of STEC Gastroenteritis: Is There a Role for Probiotics?

Shiga toxin-producing Escherichia Coli (STEC) infections routinely run as a common gastroenteritis, but in many cases they may evolve towards hemolytic uremic syndrome (HUS). HUS is a rare disease characterized by microangiopathic hemolytic anemia, thrombocytopenia, and acute renal failure. Gut microorganisms have a fundamental impact on human physiology, because they modulate normal intestinal functions and play a pivotal role in influencing the local and systemic immune responses. Despite surveillance established in many countries and major progresses in the understanding of STEC-HUS mechanisms, no specific treatment is currently available. Targeting the gut microbiota could represent a new potential therapeutic strategy in STEC infection. In this paper, we reviewed the current knowledge about microbiota characteristics of patients with STEC infections, as well as in vitro and in vivo evidence of probiotic supplementation in managing STEC gastroenteritis and in HUS onset prevention.

Are pre-terms born timely and right immunized? Results of an Italian cohort study.

The aim of this study is to evaluate the vaccination coverage at 24 months of chronological age in a sample of preterm infants discharged by the Neonatal Intensive Care Unit (NICU) of the Bari Policlinico University General Hospital in Italy. The list of infants preterm born discharged during 2013 by the NICU was obtained by hospital database. Vaccination status of each subject at 24 months of chronological age was acquired by the Apulian Regional Vaccination Register (GIAVA). 159 preterm borns were enrolled in this study. 98.1% received the 1st dose of hexavalent vaccine and 98.7% the 1st dose of pneumococcal conjugate vaccine. The 8.8% of hexavalent vaccinations were performed during hospitalization. The percentage of immunized subjects decreased to 91.2% and 87.3% for the 2nd and 3rd dose of hexavalent vaccine and to 90.6% and 86.1% for the 2nd and 3rd dose of pneumococcal conjugate vaccine. Coverage for MMR, MEN C and Varicella vaccines were, respectively 76.4%, 86.0% and 80.9%. Pre-terms received the vaccinations later than the age recommended by public health guidelines. Age at the immunization, for all vaccines, seems to increase for lower gestational age and birth weight and for higher length of hospitalization. This study shows a high risk of vaccine delay among pre-terms born. There is a strong need to improve specific vaccination strategies for this group. Neonatologists might play a key role in informing parents about the vaccination schedule at the moment of NICU discharge and during follow-up, also preparing correct time schedule.

Mean Platelet Volume, Vitamin D and C Reactive Protein Levels in Normal Weight Children with Primary Snoring and Obstructive Sleep Apnea Syndrome.

INTRODUCTION: Studies on Mean Platelet Volume (MPV) in children with Sleep Disordered Breathing (SDB) report conflicting results and the hypothesis of an intermittent hypoxemia leading to a systemic inflammation is reaching consensus. Vitamin D exerts anti-inflammatory properties and its deficiency has been supposed to play a role in sleep disorders. Emerging interest is rising about Primary Snoring (PS) since it is reasonable that also undetectable alteration of hypoxia might predispose to an increased production of inflammatory mediators. In this perspective, in a group of children affected by SDB, our aim was to investigate MPV, vitamin D and C Reactive Protein (CRP) levels, which had been previously evaluated separately in different studies focused only on Obstructive Sleep Apnea Syndrome (OSAS). MATERIALS AND METHODS: We enrolled 137 children: 70 healthy controls (HC), 67 affected by SDB undergoing a polysomnographic evaluation, 22 with a diagnosis of PS and 45 with a diagnosis of OSAS. All patients underwent routine biochemical evaluations including blood cell counts, CRP and vitamin D. RESULTS: Children affected by SDB had a mean age of 8.49±2.19 and were prevalently males (23 females, 34%; 44 males, 66%). MPV levels were higher in OSAS and PS when compared to HC; platelet count (PLT) and CRP levels were higher while Vitamin D levels were lower in children with SDB when compared to HC. MPV levels were correlated with PLT (r = -0.54; p<0.001), vitamin D (r = -0.39; p<0.001) and CRP (r = 0.21; p<0.01). A multiple regression was run to predict MPV levels from vitamin D, CRP and PLT and these variables significantly predicted MPV (F = 17.42, p<0.0001; adjusted R2 = 0.37). Only platelet count and vitamin D added statistically significantly to the prediction (p<0.05). CONCLUSION: The present study provides evidence of higher MPV and lower vitamin D levels in children with PS as well as in children with OSAS, and supports the underlying inflammation, hence, highlighting the importance of an early diagnosis of this previously considered benign form of SDB.

Different functional cardiac characteristics observed in term/preterm neonates by echocardiography and tissue doppler imaging.

BACKGROUND AND AIM: To establish, using echocardiography, color-flow Doppler and tissue doppler imaging (TDI), physiological values of systolic/diastolic indexes in healthy term/pre-term newborns, and to identify how different degrees of maturity influence morpho-functional cardiac alterations during the transitional period. STUDY DESIGN AND SUBJECTS: 33 term newborns (M = 19, F = 14; gestational ages: 37th-41st week), and 20 pre-term infants (M = 11, F = 9; gestational ages: 31st-36th week) admitted to our department were studied. All infants underwent to clinical and Doppler ultrasound evaluations, carried out by the third to fourth day. Investigations included: M-mode echocardiography, color-flow Doppler and TDI. OUTCOME MEASURES AND RESULTS: Term and preterm neonates differed for: interventricular septum and left systolic/diastolic ventricle diameters (p<0.01 and <0.05 respectively); left ventricle posterior wall in systole (p<0.01); shortening and ejection fraction (p<0.05). Color-flow Doppler parameters on the tricuspid (peak E, peak A, ratio E/A; p<0.05) and on the mitral (peak E and E/A ratio; p<0.01) significantly differed between the two groups. Significant differences were also present for basal left ventricular lateral wall and right ventricular lateral wall in the Ew (p<0.01 and <0.05 respectively), Sw peak (p<0.01 and <0.05 respectively), and Ew/Aw (p<0.05). The isovolumetric relax time and the E/Ew measured on the medial mitral annulus also demonstrated significant differences (p<0.01) between the two groups. CONCLUSIONS: TDI is feasible in preterm neonates and enables assessment of myocardial velocities. With increasing gestational age, higher myocardial velocities and lower E/E' Πratios were found. TDI addition to standard neonatal echocardiography may provide further important information about cardiac function.
