Arrhythmic risk profile in mitral valve prolapse: A systematic review and metanalysis of 1715 patients.

INTRODUCTION: Mitral valve prolapse (MVP) is a common clinical condition in the general population. A subgroup of patients with MVP may experience ventricular arrhythmias and sudden cardiac death ("arrhythmic mitral valve prolapse" [AMVP]) but how to stratify arrhythmic risk is still unclear. Our meta-analysis aims to identify predictive factors for arrhythmic risk in patients with MVP. METHODS: We systematically searched Medline, Cochrane, Journals@Ovid, Scopus electronic databases for studies published up to December 28, 2022 and comparing AMVP and nonarrhythmic mitral valve prolapse (NAMVP) for what concerns history, electrocardiographic, echocardiographic and cardiac magnetic resonance features. The effect size was estimated using a random-effect model as odds ratio (OR) and mean difference (MD). RESULTS: A total of 10 studies enrolling 1715 patients were included. Late gadolinium enhancement (LGE) (OR: 16.67; p = .005), T-wave inversion (TWI) (OR: 2.63; p < .0001), bileaflet MVP (OR: 1.92; p < .0001) and mitral anulus disjunction (MAD) (OR: 2.60; p < .0001) were more represented among patients with AMVP than in NAMVP. Patients with AMVP were shown to have longer anterior mitral leaflet (AML) (MD: 2.63 mm; p < .0001), posterior mitral leaflet (MD: 2.96 mm; p < .0001), thicker AML (MD: 0.49 mm; p < .0001), longer MAD length (MD: 1.24 mm; p < .0001) and higher amount of LGE (MD: 1.41%; p < .0001) than NAMVP. AMVP showed increased mechanical dispersion (MD: 8.04 ms; 95% confidence interval: 5.13-10.96; p < .0001) compared with NAMVP. CONCLUSIONS: Our meta-analysis proved that LGE, TWI, bileaflet MVP, and MAD are predictive factors for arrhythmic risk in MVP patients.

Frequency and type of domestic injuries among children during COVID-19 lockdown: what changes from the past? An Italian multicentre cohort study.

Accidents are the main cause of injury in children, more than half events happen at home. Aims of this study were to assess if SARS-CoV-2 lockdown influence emergency department (ED) visits due to children domestic accident (DAs) and to identify factors associated with hospitalization. This was a multicentre, observational, and retrospective cohort study involving 16 EDs in Italy and enrolling children (3-13 years) receiving a visit in ED during March-June 2019 and March-June 2020. Risk factors for hospitalization were identified by logistic regression models. In total, 8860 ED visits due to domestic accidents in children occurred before (4380) and during (4480) lockdown, with a mean incidence of DA of 5.6% in 2019 and 17.9% in 2020 (p < 0.001) (IRR: 3.16; p < 0.001). The risk of hospitalization was influenced by the type of occurred accident, with fourfold higher for poisoning and twofold lower risk for stab-wound ones. In addition, a higher risk was reported for lockdown period vs 2019 (OR: 1.9; p < 0.001), males (OR: 1.4; p < 0.001), and it increased with age (OR: 1.1; p < 0.001).    Conclusions: The main limitation of this study is the retrospective collection of data, available only for patients who presented at the hospital. This does highlight possible differences in the total number of incidents that truly occurred. In any case, the COVID-19 lockdown had a high impact on the frequency of DAs and on hospitalization. A public health campaign aimed at caregivers would be necessary to minimize possible risks at home. What is Known: • In Italy, domestic accidents are the second leading cause of paediatric mortality after cancer. • During the first SARS-CoV-2 lockdown in 2020, a sharp decrease in the total number of Emergency Departments visits for all causes was observed, both in children and in adults. What is New: • During the first SARS-CoV-2 lockdown in 2020, domestic accidents involving children increased threefold from the previous year. • Higher risk of hospitalization was showed in minors accessing during 2020 vs 2019, in males than in females and it increased with advancing age. Considering the type of injury, a significant higher risk of hospitalization for poisoning was observed.

Prognostic value of two-dimensional strain in early ischemic heart disease: A 5-year follow-up study.

INTRODUCTION: Two-dimensional strain echocardiography (2D-SE) is a reliable method for measuring deformation of the left ventricle. AIM OF THE STUDY: Aim of the study was to determine changes in 2D-SE parameters over time collected during dipyridamole stress echo-cardiography (dipy-stress) and prognosis of patients with non-diagnostic dipy-stress results. METHODS: In the first phase of the study, assessment of a prospective enrolled population with a non-diagnostic dipy-stress test result was conducted, checking through coronary CT angiography (CCTA) the presence of coronary artery disease (CAD). In the follow-up phase, an echocardiographic re-evaluation and outcome analysis during a mean follow-up of 78 months was carried out. RESULTS: In the first phase, Global Circumferential Strain (GCS) values were similar in the CCTA positive and CCTA negative groups at rest and after stress. For Global Longitudinal Strain (GLS), there was a significant reduction (p < .0001) in the CCTA positive group compared to the CCTA negative group. After 78 ± 9 months none of the enrolled patients experimented cardiac events. Values of GCS, both at rest and after stress, did not differ statistically comparing follow-up values with baseline ones. No statistically significant changes were seen in the same analysis for GLS rest and stress values, between baseline and follow-up in the two groups. CONCLUSIONS: Performing 2D-SE during dipy-stress can detect mild CAD that conventional stress-tests miss. Patients with mild coronary stenosis may have a favorable mid-term prognosis, but efforts should be made to investigate the decrease trend in GLS, at rest and after stress, reported in this patient group.

The use of biological agents in pregnant women affected by autoimmune disorders: Why we need more research of this neglected area.

Women of childbearing age are largely affected by several autoimmune disorders (the estimates range between 1.5 and 10 per 10,000). The increasing number of effective biological agents has dramatically revolutionized the treatment of these clinical conditions, ameliorating the patient's quality of life. The use of these agents by women during pregnancy is growing to ensure the disease activity control and avoid adverse health outcomes. However, for many newer biological agents, the degree of information concerning their use in pregnancy is often incomplete to perform a conclusive risk assessment on fetal and maternal health given the exclusion of this specific population from pharmacological clinical trials. More recently, the COVID-19 pandemic has confirmed the unacceptable inequities of pharmacological research and medical treatment for pregnant and lactating women, exacerbating the need for filling the gaps of quantitative and qualitative pharmacology data in this sensitive population. ere we summarize (i) what is already known about safety and effectiveness of biological agents in this understudied population (with specific focus on pregnancy-related health outcomes), and what we are going to learn from the on-going studies among pregnant women treated with biological agents; (ii) the methodological and ethical considerations that characterize the pharmacological research in pregnancy, also discussing emerging evidence on the use of therapeutic drug monitoring (TDM) in this clinical setting.

Analysis on chronic pain management: Focus on the Italian network.

The Italian Law 38/2010, 'Dispositions to guarantee access to Palliative Care and Pain Management' orders that the health care systems of Italian regions create dedicated structures for palliative care and pain therapies, according to a specific organizational model called 'Hub-Spoke', to ensure the diagnostic-therapeutic continuity of patients affected by chronic pain (CP). The aim of our study was to investigate the Italian pain therapy network, 8 years following the approval of the Law. We sent a questionnaire to the national health representatives operating in CP management. The main result emerging from the analysis concerns the management of mini-invasive procedures, showing that 93.2% of the responding facilities carry out invasive procedures, 6.8% do not perform them and that 100% of the facilities belonging to 12 regions provided these procedures, while in eight regions more than 80%. Finally, only 38.5% of facilities declared to have a shared protocol with the relevant territorial facilities in order to guarantee the process of care and assistance of patients affected by CP. In conclusion, our study demonstrated the efficacy of the organizational model in most of the responding facilities, although the territorial management of patients after their hospital discharge should be strengthened.

Maternal Low-Grade Chronic Inflammation and Intrauterine Programming of Health and Disease.

Overweight and obesity during pregnancy have been associated with increased birth weight, childhood obesity, and noncommunicable diseases in the offspring, leading to a vicious transgenerational perpetuating of metabolic derangements. Key components in intrauterine developmental programming still remain to be identified. Obesity involves chronic low-grade systemic inflammation that, in addition to physiological adaptations to pregnancy, may potentially expand to the placental interface and lead to intrauterine derangements with a threshold effect. Animal models, where maternal inflammation is mimicked by single injections with lipopolysaccharide (LPS) resembling the obesity-induced immune profile, showed increased adiposity and impaired metabolic homeostasis in the offspring, similar to the phenotype observed after exposure to maternal obesity. Cytokine levels might be specifically important for the metabolic imprinting, as cytokines are transferable from maternal to fetal circulation and have the capability to modulate placental nutrient transfer. Maternal inflammation may induce metabolic reprogramming at several levels, starting from the periconceptional period with effects on the oocyte going through early stages of embryonic and placental development. Given the potential to reduce inflammation through inexpensive, widely available therapies, examinations of the impact of chronic inflammation on reproductive and pregnancy outcomes, as well as preventive interventions, are now needed.

Effect of human embryonic morphological development on fetal growth parameters: the Rotterdam Periconceptional Cohort (Predict Study).

RESEARCH QUESTION: Is embryonic morphological development according to the Carnegie stages associated with pregnancy outcome? DESIGN: In a tertiary hospital-based cohort, 182 singleton non-malformed pregnancies were selected. Serial transvaginal three-dimensional ultrasound (3D-US) scans were carried out between 6+0 and 10+2 gestational weeks. Embryonic development was annotated according to the morphological criteria of the Carnegie classification using a virtual reality system. Second-trimester biparietal diameter, head circumference, abdominal circumference and femur length measurements were retrieved from medical records. Z-scores were calculated for mid-pregnancy estimated fetal weight (EFW) and newborn birth weight. Associations between longitudinal Carnegie stages and fetal growth parameters were investigated using linear mixed models, with subgroup analysis based on fetal gender. RESULTS: A total of 576 first-trimester 3D-US scans were analysed (median of three scans per pregnancy). Embryonic development was positively associated with EFW z-score (ß = 0.69; 95% CI 0.51 to 0.86; P < 0.001), biparietal diameter and femur length, but not with head circumference, abdominal circumference and birth weight z-score. After stratification for fetal gender, positive associations for both males and females were confirmed between embryonic development and EFW z-scores. Moreover, opposite gender-specific associations were detected between embryonic development and birth weight z-scores (males: ß = 0.37; 95% CI 0.04 to 0.70; P < 0.05; females: ß = -0.36; 95% CI -0.62 to -0.10; P < 0.01). CONCLUSIONS: Human embryonic development according to the Carnegie stages is associated with fetal growth parameters with gender-specificity of birth weight. These results emphasize the importance of the first-trimester of pregnancy, raising the morphological staging of the embryo as a new methodology for early risk assessment and improvement of subsequent fetal growth parameters.

Effect of pH control during rice fermentation in preventing a gliadin P31-43 entrance in epithelial cells.

Coeliac disease is an increasingly recognised pathology, induced by the ingestion of gluten in genetically predisposed patients. Undigested gliadin peptide can induce adaptive and innate immune response that unleash the typical intestinal mucosal alterations. A growing attention is paid to alternative therapeutic approaches to the gluten-free diet: one of these approaches is the use of probiotics and/or postbiotics. We performed lactic fermentation of rice flour with and without pH control, using Lactobacillus paracasei CBA L74 as fermenting strain. We evaluated bacterial growth, lactic acid production during fermentation and gliadin peptide P31-43 entrance in CaCo-2 cells with and without pH control. When pH control was applied no differences were observed in terms of bacterial growth; on the contrary, lactic acid production was greater, as expected. Both samples could inhibit the P31-43 entrance in CaCo-2 cells but the effect was significantly greater for samples obtained when the pH control was applied.

Multiple micronutrient needs in pregnancy in industrialized countries.

BACKGROUND: As nutritional deficiencies are known to lead to adverse pregnancy outcomes, a woman's nutritional status should be assessed preconceptionally with the goal of optimizing maternal, fetal and infant health. Worldwide micronutrient intakes do not fit pregnancy requirements, so that their supplementation is recommended from the beginning of pregnancy in most of the low- and middle-income countries. Conversely, data on multiple supplementation in developed countries appear few and controversial. Key Message: Although a balanced diet is generally accessible in industrialized countries, a switch to a high-fat and low-quality diet has led to an inadequate vitamin and mineral intake during pregnancy, so that recent data show the micronutrient intake and supplementation to be lower than recommended even in high-income countries, particularly for iron, folic acid, calcium and vitamin D. CONCLUSIONS: Currently, even if there is insufficient evidence to support routine supplementation at the population level, except for periconceptional folate supplementation, these results need to be evaluated at an individual level in order to avoid nutritional deficiencies and to encourage women to establish healthful dietary practices prior to conception. The new goal in industrialized countries needs to be an individualized approach that takes account of the phenotypic, genotypic and metabolic differences among individuals of the same population.

Impact of Maternal Environment and Inflammation on Fetal Neurodevelopment.

During intrauterine life, external stimuli including maternal nutrition, lifestyle, socioeconomic conditions, anxiety, stress, and air pollution can significantly impact fetal development. The human brain structures begin to form in the early weeks of gestation and continue to grow and mature throughout pregnancy. This review aims to assess, based on the latest research, the impact of environmental factors on fetal and neonatal brain development, showing that oxidative stress and inflammation are implied as a common factor for most of the stressors. Environmental insults can induce a maternal inflammatory state and modify nutrient supply to the fetus, possibly through epigenetic mechanisms, leading to significant consequences for brain morphogenesis and neurological outcomes. These risk factors are often synergic and mutually reinforcing. Fetal growth restriction and preterm birth represent paradigms of intrauterine reduced nutrient supply and inflammation, respectively. These mechanisms can lead to an increase in free radicals and, consequently, oxidative stress, with well-known adverse effects on the offspring's neurodevelopment. Therefore, a healthy intrauterine environment is a critical factor in supporting normal fetal brain development. Hence, healthcare professionals and clinicians should implement effective interventions to prevent and reduce modifiable risk factors associated with an increased inflammatory state and decreased nutrient supply during pregnancy.

A Preliminary Evaluation of the Prognostic Role of HER-2 and HER-3 Immunohistochemical Expression in Canine Melanomas.

Canine melanoma is a malignant and aggressive neoplasm showing clinical, histological, and molecular features similar to the human counterpart. In human medicine, epidermal growth factor receptors (EGFRs) have already been suggested as prognostic markers and potential therapeutic targets in cutaneous melanoma. The aim of this study was to evaluate the expression of HER-2 and HER-3 in canine melanomas by immunohistochemistry and correlate their expression to the clinicopathological parameters of the examined tumors. Thirty-seven canine melanoma samples were recruited. Data regarding signalment and clinical parameters were also collected. The population was composed of 18 cutaneous, 16 oral/mucosal, and three digital/foot pad melanomas. Histopathological investigations were carried out to analyze histological type, ulceration, and mitotic count. On each sample, immunohistochemistry was performed using an anti-Melan-A or anti-Melanoma antigen, i.e., anti-HER-2 and anti-HER-3 antibodies. HER-2 and HER-3 positivity were classified using already established scoring criteria and a statistical analysis was carried out. The results highlighted that HER-2 expression was observed in 48.6% of the samples and HER-3 expression in 18.9%. The highest HER 2 score (3+) was recorded in 16.2% of the samples, while the coexpression of the two receptors was detected in 13.5% of the samples. A statistically significant association (p < 0.05) was observed between the expression of HER-2 and HER-3 and the presence of ulceration in oromucosal tumors. This work confirms the expression of HER-2 and HER-3 in canine melanomas and suggests a putative association with negative prognostic parameters. Further studies are necessary to strengthen these data by increasing the samples size and combining pathological examinations with molecular biology in the investigation of EGFR family receptors.

Associations between Maternal Nutritional Status, Hemodynamic Parameters, and Delivery Outcomes in Low-Risk Pregnancies: A Prospective Observational Study.

Maternal nutritional status represents a pivotal predictor of pregnancy outcome. This prospective observational study investigates the associations between maternal characteristics and nutritional habits at term, hemodynamic parameters, and pregnancy outcomes. Healthy women with singleton uncomplicated pregnancies were enrolled at 36-41 gestational weeks. At enrollment, a nutritional score (0-10) was calculated in order to quantify maternal adherence to a healthy diet and lifestyle. Maternal hemodynamic parameters were assessed by using the Ultrasonic Cardiac Output Monitor (USCOM), including cardiac output (CO), systemic vascular resistance (SVR) and Smith-Madigan inotropy index (SMII). Pregnancy outcomes were recorded at delivery. Associations between maternal characteristics and nutritional score, hemodynamic parameters, and pregnancy outcomes were investigated by using multi-adjusted generalized linear models. In total, 143 pregnancies were enrolled. Pregestational body mass index (BMI) was positively associated with SVR, and negatively associated with CO and SMII. Additionally, a positive association was detected between the nutritional score and SMII. Finally, CO was positively associated with birth and placental weight, while RVS showed a negative association with birth and placental weight. This study shows that maternal derangements in nutritional status and habits are associated with a compromised hemodynamic profile at term, with additional impacts on intrauterine growth.

Age at Tumor Diagnosis in 14,636 Canine Cases from the Pathology-Based UNIPI Animal Cancer Registry, Italy: One Size Doesn't Fit All.

Cancer is the most common cause of death in adult dogs. All dogs would benefit from early diagnosis, but there are no specific guidelines regarding the schedule of cancer screening in companion animals. The aim of this study was to retrospectively evaluate the age at diagnosis in Italian oncological canine patients. A total of 14,636 canine histologically confirmed neoplastic cases were coded according to the Vet-ICD-O-canine-1 and stratified by malignancy, sex, neutering status, breed, cephalic index, body size, and tumor type. Differences in age distribution were analyzed and the influence of these variables on the time of first malignancy diagnosis was assessed using an event history analysis model. The median age at diagnosis for benign and malignant tumors was 9 and 10 years, respectively. Intact and purebred dogs were diagnosed earlier, but the median age differed significantly by breed. The earliest age at diagnosis was recorded for lymphomas and mast cell tumors. The model showed an accelerating effect of large size, brachy- and dolichocephaly, and sexual integrity in female dogs on the time of malignancy diagnosis. Our results confirm that a "one-size-fits-all" approach to cancer screening is not accurate in dogs and provide relevant data that may lead to the establishment of breed-based screening schedules.

SGLT2 inhibitor therapy in patients with advanced heart failure and reduced ejection fraction.

AIMS: Sodium-glucose cotransporter inhibitors (SGLT2-i) improve outcomes in patients with heart failure (HF) and reduced ejection fraction (HFrEF). However, evidence in patients with advanced HF is lacking. We aimed to determine the effect of SGLT2-i in advanced HFrEF compared to their effect on a non-advanced population. METHODS: Consecutive HFrEF outpatients who started SGLT2-i were observed for 6-months. Patients were categorized as having advanced or non-advanced HFrEF. The primary outcome was the trend of NTproBNP in the two groups. Secondary outcomes included changes in New York Heart Association (NYHA) class, glomerular filtration rate (GFR), and ejection fraction (LVEF). The association between advanced HF diagnosis and including N-terminal pro-brain natriuretic peptide (NTproBNP) reduction was tested using multivariate analysis. RESULTS: Overall, 105 patients (45 advanced, 60 non-advanced) were included. Mean age was 56 ± 10 years, 22 % were female, and 35 % had ischemic heart disease. Median NTproBNP at baseline for advanced and non-advanced patients was 1672pg/ml (IQR 520-3320) vs. 481 pg/ml (IQR 173-917), respectively (p < 0.001). At follow-up, only non-advanced patients reduced their NTproBNP (-32 % (95 % CI -51 to -3), p < 0.001), while advanced patients had an increase in NTproBNP. LVEF and NYHA class improved only in non-advanced patients. GFR was stable in both subgroups. At multivariate analysis a diagnosis of advanced HF was independently associated with a reduced probability of NTproBNP reduction (OR 0.041 (95 % CI 0.002-0.752), p = 0.031). Only one patient discontinued the drug due to side effects. CONCLUSION: In advanced HFrEF, SGLT2-i do not impact on NTproBNP, LVEF or NYHA class but are well tolerated.

Perceived Parenting Stress Is Related to Cardiac Flexibility in Mothers: Data from the NorBaby Study.

Heart rate variability (HRV) is an indicator of autonomic nervous system activity, and high levels of stress and/or depressive symptoms may reduce HRV. Here, we assessed whether (a) parental stress affected HRV in mothers during the perinatal period and whether this is mediated by bonding and (b) whether antenatal maternal mental states, specifically repetitive negative thinking, depressive symptoms, and pregnancy-related anxiety, have an impact on infant HRV, and lastly, we investigated (c) the relationship between maternal HRV and infant HRV. Data are from the Northern Babies Longitudinal Study (NorBaby). In 111 parent-infant pairs, cardiac data were collected 6 months after birth. In the antenatal period, we used the Pregnancy-Related Anxiety Questionnaire-Revised, the Edinburgh Postnatal Depression Scale, and the Perseverative Thinking Questionnaire; in the postnatal period, we used the Parenting Stress Index and the Maternal Postnatal Attachment Scale. Higher levels of perceived parenting stress but not depressive symptoms were associated with lower HRV in mothers (τ = -0.146), and this relationship was not mediated by maternal bonding. Antenatal maternal mental states were not associated with infant HRV. There was no significant correlation between maternal HRV and infant HRV. Our observational data suggest that perceived stress reduces cardiac flexibility. Future studies should measure HRV and parenting stress repeatedly during the perinatal period.

Placental Bioenergetics and Antioxidant Homeostasis in Maternal Obesity and Gestational Diabetes.

Maternal obesity has been associated with short- and long-term risks of pregnancy-perinatal adverse events, possibly due to alterations of placental mitochondrial bioenergetics. However, several detrimental mechanisms occurring in the placentas of women with obesity still need to be clarified. Here, we analyzed placental mitochondrial features and oxidative environment of 46 pregnancies in relation to pre-pregnancy BMI. Seventeen Caucasian normal-weight (NW) and twenty-nine women who were obese (OB) were enrolled. The protein expression of mitochondrial CypD and electron transfer chain complexes (C) I-V were measured, as well as ATP production and oxygen consumption rates (OCRs). The protein levels of the pro/anti-oxidant enzymes TXNIP, SOD2, and PON2 were also analyzed. Despite no differences in CypD expression, OCRs were significantly lower in OB vs. NW women. Accordingly, ATP synthase (CV) levels and ATP content were decreased in OB women, positively correlating with placental efficiency, suggesting a link between ATP deficiency and placental dysfunction. SOD2 expression negatively correlated with maternal BMI, indicating a possible impairment of antioxidant defenses with increasing BMI. These changes were worsened in 10 OB women presenting with gestational diabetes mellitus. Overall, these results suggest alterations of placental bioenergetics in pregnancies of women with obesity, possibly leading to placental dysfunction and altered fetal development and programming.

A real-life prospective blinded evaluation of placental biometry and macroscopic morphology from 1008 unselected consecutive pregnancies.

INTRODUCTION: The study of the macroscopic appearance of the placenta may represent a useful tool to understand the pathophysiology of adverse pregnancy outcomes. The aim of this study was to evaluate biometry and morphology of placentas in relation to maternal, neonatal and pregnancy course characteristics. METHODS: Clinical and placental data (biometry and macroscopic features of chorionic disk and adnexa) from unselected consecutive singleton pregnancies were recorded at the same Institution. Placental efficiency was approximated as ratio between fetal and placental weight (FPR). The total population was grouped according to the presence of any maternal comorbidity or pregnancy complication (group 1), neonatal complications diagnosed only at birth (2) and absence of any comorbidity (3). Multi-adjusted general linear and logistic regression models were performed to analyze associations between groups and placental biometry and morphology. RESULTS: The study population counted 1008 pregnancies: 576 (57.2 %) classified as group 1, 76 (7.5 %) as group 2 and 356 (35.3 %) uncomplicated controls (group 3). In multivariate models adjusted for confounding factors, no significant differences in placental biometry and macroscopic features were observed among the three groups. Maternal BMI was significantly associated with higher placental and birth weight and lower FPR; moreover FPR was significantly higher in pregnancies carrying males compared to female neonates. DISCUSSION: Maternal comorbidity or pregnancy disease was not associated with significant changes in placental macroscopic biometry and morphology. Conversely, maternal pregestational BMI and fetal sex impact on placental biometry and efficiency, suggesting different intrauterine adaptations in obese mothers and in male and female fetuses.

Platelet rich plasma for primary macular hole: A case series.

OBJECTIVE: To evaluate the anatomical and functional macular results and rate of complications following surgical treatment of primary macular hole (MH) with autologous platelet rich plasma (a-PRP) use. DESIGN: retrospective, interventional, non-randomized case series. PARTECIPANTS AND METHODS: A cohort of 9 consecutive patients from January 1, 2019 to August 31, 2021 who underwent vitrectomy with a-PRP use for primary MH were included. Anatomical results based on spectral domain- optical coherence tomography (SD-OCT) and visual acuity were analyzed. RESULTS: 10 pseudophakic eye of 9 patients were enrolled. Six patients were female and three patients were male. The mean age was 69.9 years ± 1.48. The baseline MH minimum diameter was 486.1 µm ± 37.1, and mean pre operative best-corrected visual acuity (BCVA) was 0.91 ± 0.03 logMAR (Snellen equivalent 20/160). Mean 1 month post operative BCVA was 0.81 ± 0.57 logMAR (Snellen equivalent 20/130; p = 1.000); mean 3 month post operative BCVA was 0.66 ± 0.04 logMAR (Snellen equivalent 20/90; p = 0.006); mean 6 month post operative BCVA was 0.6 ± 0.04 logMAR (Snellen equivalent 20/80; p < 0.001). In all eyes, 10/10 (100%), there was a complete MH closure at 6 months follow up: 5 eyes (50%) with a U-type closure pattern, 4 eyes (40%) with a V-type pattern and 1 eye (10%) with an irregular foveal contour closure at 6 month follow-up. No ocular and systemic complications were reported. CONCLUSION: The a-PRP use is a successful and promising vitreoretinal surgical technique option for primary MH.

MI2AMI-CS: A meta-analysis comparing Impella and IABP outcomes in Acute Myocardial Infarction-related Cardiogenic Shock.

BACKGROUND: Cardiogenic Shock (CS) complicating acute myocardial infarction (AMI) poses a significant mortality risk, suggesting the opportunity to implement effective mechanical circulatory support strategies. The comparative efficacy of Intra-Aortic Balloon Pump (IABP) and Impella in managing CS-AMI remains a subject of investigation. OBJECTIVE: This meta-analysis aims to evaluate the comparative effectiveness of Impella and IABP in managing CS-AMI, exploring mortality and adverse events. METHODS: A systematic search of major databases from inception to November 2023 identified eight studies, comprising 10,628 patients, comparing Impella and IABP in CS-AMI. Retrospective studies (preferably Propensity-matched) and Randomized Clinical Trials (RCTs) were included. RESULTS: Impella use exhibited significantly higher mortality (57% vs. 46%; OR: 1.44, 95% CI: 1.29-1.60; p < 0.001) and major bleeding (30% vs 15%; OR: 2.93, 95% CI: 1.67-5.13; p < 0.001). CONCLUSIONS: In unselected CS-AMI patients, Impella usage is associated with significantly higher mortality and major bleeding.
