Introduction: Pregnancy is contraindicated in women with pulmonary hypertension (PH), yet many still decide to pursue pregnancy. Hypothesis: We hypothesized improved maternal mortality with PH at our center’s cardio-obstetrics program and sought to identify factors to estimate the risk of major adverse cardiac events (MACE). Methods: Pregnant women with right ventricular systolic pressure (RVSP) ≥35 mmHg or tricuspid regurgitant velocity > 2.8 m/s on transthoracic echocardiogram (TTE) were identified. Women with intermediate to high probability PH by ESC criteria (TTE or catheterization, n = 70) were classified using the 6 th World Society of PH definitions. Results: In 70 women with PH (30 ± 6 years-old, RVSP 52 ± 16 mmHg) there were 12 (17%) with WHO Group 1 PH, 45 (64%) with Group 2 PH, 4 (6%) with Group 3 PH and 9 (13%) with Group 5 PH (Figure A). Baseline characteristics were similar except: Group 1 PH had 83% on prostacyclin (PC) therapy, higher RVSP (78 ± 20 mmHg vs. Groups 2 (46 ± 9), 3 (44 ± 2 mmHg) and 5 PH (48 ± 10mmHg), p<0.01), and compared to Group 2 PH, more Group 1 PH women were diagnosed pre-pregnancy (9 (75%) vs. 12 (27%), p = 0.01) and had cardio-obstetrics care (10 (83%) vs. 16 (36%), p < 0.01) (Figure B - E). There were no peripartum deaths, however 3 (4.3%) women with Group 2 PH had late mortality (7 ± 4 months post-partum). MACE occurred in 24 (34%) women and was more likely in those with: NYHA FC ≥ 2 (95% CI 4.7-57, p < 0.01), pre-eclampsia (95% CI 1.2-13, p = 0.03), RVSP >50 mmHg (95% CI 1.3-10, p = 0.02) and LVEF <50% (95% CI 1.1-8.8, p = 0.04) (Figure F). Preterm birth occurred in 32 (49%) pregnancies, with no neonatal mortality. Conclusion: To conclude, in a large single center cohort we report 100% 1-year survival in Groups 1, 3, and 5 PH, with most Group 1 PH patients on PC therapy and under cardio-obstetrics care. We identify Group 2 PH as an under-recognized group for adverse outcomes in pregnancy, with NYHA FC, pre-eclampsia, RVSP >50 mmHg and LVEF <50% associated with increased MACE.

ObjectiveThis study sought to determine the prevalence, predictors, prognostic relevance and evolution of pulmonary hypertension (PH) (mean pulmonary artery pressure ≥25 mm Hg) in adult patients with a subaortic right ventricle (RV) in a biventricular circulation (2V-RV).MethodsWe analysed retrospective data from patients with 2V-RV undergoing cardiac catheterisation in our centre between 2000 and 2018. Echocardiographic assessment of subpulmonary ventricular pressures (left ventricular systolic pressure (LVSP)), age and B-type natriuretic peptide (BNP) were assessed as PH screening tools. Kaplan-Meier curves examined time to a composite outcome of death, transplant or ventricular assist device (VAD). Data from repeat catheterisations were analysed to evaluate PH changes over time, including the effects of therapy.ResultsA total of 141 patients (median age 39 (IQR 33–45) years, 68% men) underwent 191 cardiac catheterisations. At baseline, 55% had PH (isolated postcapillary 24%, combined precapillary and postcapillary 26% and precapillary 5%). BNP (area under the curve 0.80; 95% CI 0.72 to 0.88; p<0.0001), but not age at catheterisation or echocardiographic estimates of LVSP were associated with the presence of PH. The absence of PH and BNP <100 pg/mL discriminated a subgroup at very low risk during short-term (2.5 (1.3–3.9) years) follow-up (p<0.0001). Diuretics, milrinone and VAD improved haemodynamics over time.ConclusionPH is prevalent in patients with 2V-RV even when asymptomatic. It is difficult to identify by echocardiography and most importantly, is strongly associated with adverse outcomes. PH affects prognosis and transplant options for this patient group and yet is often amenable to treatment. Awareness of these results ought to lower the threshold for invasive haemodynamic assessment and may change the management of failing patients with 2V-RV.

Increased pulmonary hypertension (PH) awareness in the general public and among health providers has led to an increase in referral of patients who are found to have elevated estimates of pulmonary artery systolic pressure (PASP) on a transthoracic echocardiogram (TTE), without other strong features suggestive of precapillary PH (pulmonary arterial hypertension; PAH). Some of these patients undergo TTE as part of their workup for unexplained dyspnea that appears out of proportion to their other comorbidities. Many of these patients are older individuals with underlying conditions such as systemic hypertension (HTN), diabetes mellitus (DM), coronary artery disease (CAD), and obstructive sleep apnea (OSA). While some of them may have PAH, accumulated experience in the PH community suggests that many of these patients will be ultimately found to have elevated left ventricular (LV) filling pressures and impaired LV relaxation as the cause of their dyspnea and elevation of pulmonary pressures on TTE.12 These findings are consistent with a form of Group 2 PH termed LV diastolic dysfunction, more recently termed heart failure with preserved left ventricular systolic function (HFpEF) (Table 1).2 Other forms of Group 2 PH, defined as “pulmonary hypertension owing to left-sided heart disease,” include LV systolic dysfunction or left-sided valvular disease.2 For the purpose of this article, the term pulmonary venous hypertension (PVH) will be used to refer to Group 2 PH, HFpEF. Being able to accurately discriminate PAH (precapillary; Group 1 PH) from PVH (postcapillary; Group 2 PH) is critical to determine and apply the appropriate treatment course. This is a difficult, yet frequently encountered clinical dilemma, which can fall into a “gray zone” with respect to clinical classification. We will provide important clinical features that should heighten the clinician's awareness and suspicion of this rapidly growing phenomenon. These features are critical when trying to differentiate PAH (Group 1 PH) from PVH (Group 2 PH).

Abstract Aims The definition of pulmonary hypertension (PH) requires the documentation of mean pulmonary arterial pressure (PAPm) ≥20 mmHg at rest, assessed by right cardiac catheterization. This condition can characterize multiple clinical conditions with different pathophysiological and haemodynamic aspects. Specifically, in pulmonary arterial hypertension (IAP) (Group 1), the increase in PAP is due to an intrinsic pathology of the pulmonary microcirculation; Group 2 includes the forms of IP associated with a pathology of the left heart; Group 3 includes all pathologies of the pulmonary parenchyma and/or hypoxic conditions that lead to a secondary impairment of the small circulation; Group 4 identifies patients with chronic thromboembolic pulmonary heart (CPCTE); finally, Group 5 includes rare clinical conditions in which IP is linked to direct involvement or ab extrinsic compression of the pulmonary vessels. Methods and results To examine the number of deaths and the differences between the various subgroups, we analyzed the follow-up of approximately 76 patients (64.30 ± 13.20 years, 37% male) enrolled in the Pulmonary Hypertension Clinic of the San Giovanni AOU Dio and Ruggi d’Aragona of Salerno from 2014 to 2020 excluding patients with IP under definition and those ‘screened’ who did not show pulmonary hypertension at rest. At each visit, the patients were subjected to anamnestic data collection, physical examination, measurement of blood pressure, heart rate, arterial saturation, transthoracic cardiac echo color Doppler at rest, attribution of the functional class NYHA, evaluation of functional capacity by performing the test of the 6-min walk test (6MWT) and possible programming of right cardiac catheterization. From the data analysis it was found that 26 patients (34.21%, 55.81 ± 13.90 years, 27% males) were affected by IP group 1; 15 patients (19.48%, 74.12 ± 6.26 years, 20% male) were affected by IP group 2; 14 patients (18.18%, 63.34 ± 11.52 years, 71% male) were affected by IP group 3; 12 patients (15.58%, 67.22 ± 11.53 years, 33% male) were affected by IP group 4; 2 patients (2.60%, 71.57 ± 12.48 years, 0% male) were affected by IP group 5; 7 patients (9.09%, 70.07 ± 8.27 years, 57% male) were affected by group 2–3 mixed IP. Analysing the number of deaths, of the 76 patients, 17 deaths were recorded in total (22.37%). All patients in group 1 had been treated with specific therapy and survival was 88% at 3 years. Of the three deaths (12%) in this group, one patient had idiopathic PAH non-responder to pulmonary vasoreactivity test, one patient belonged to the IAP subgroup associated with congenital heart shunt but with concomitant lung disease, and the third patient belonged to the IAP subgroup associated with connective tissue disease (specifically Takayasu’s arteritis). From the analysis of the idiopathic IAP subgroup it emerged that the patients were all women, with an average age of 50.81 ± 3.98 years, and that the deceased patient was distinguished at the first visit from the other patients for: a history of arterial hypertension, dysthyroidism, and obesity; worst NYHA class (III vs. II), elevated heart rate (102 vs. 70.00 ± 7.07 b.p.m.) and blood pressure (SBP: 150.00 vs. 127.50 ± 10.61; DBP 90.00 vs. 75.00 ± 7.07 mmHg) at rest at the clinic visit. Transthoracic echocardiography revealed elevated PAPs values (100.00 vs. 42.50 ± 20.51 mmHg), low TAPSE values (20.00 vs. 26.50 ± 3.54 mm), reduced pulmonary acceleration time (ACT 60 ms), enlargement of the right atrium (area 22 cm2), worst exercise tolerance parameters (6MWT 300 m and 86% final SO2 vs. 427.50 ± 74.25 m and 96.50 ± 0.71% final SO2). Conclusions The percentage of deaths in the different groups appears very heterogeneous, especially if we consider the six deaths (42.86%) in group 3 and three deaths (42.86%) in patients with mixed IP groups 2 and 3. In these two groups, age and advanced NYHA class were the most representative prognostic factors. On the other hand, analysing patients belonging to the idiopathic IAP subgroup, a worse prognosis is entrusted to the negativity of the vasoreactivity test, to the presence of cardiovascular comorbidities (arterial hypertension and dysthyroidism in our case), to worse echocardiographic values (PAPs, TAPSE, ACT, atrial area right) and reduced functional capacity at the 6MWT. However, early treatment and innovative drugs together with a careful strategy have been allowed.

Background: We hypothesized that perioperative HbA1c influenced the pattern and outcomes of Lower Extremity Amputation (LEA). Methods: A retrospective analysis was conducted for all patients who underwent LEA between 2000 and 2013. Patients were categorized into 5 groups according to their perioperative HbA1c values [Group 1 (<6.5%), Group 2 (6.5-7.4%), Group 3 (7.5-8.4%), Group 4 (8.5-9.4%) and Group 5 (≥9.5%)]. We identified 848 patients with LEA; perioperative HbA1c levels were available in 547 cases (Group 1: 18.8%, Group 2: 17.7%, Group 3: 15.0%, Group 4: 13.5% and Group 5: 34.9%). Major amputation was performed in 35%, 32%, 22%, 10.8% and 13.6%, respectively. Results: The overall mortality was 36.5%; of that one quarter occurred during the index hospitalization. Mortality was higher in Group 1 (57.4%) compared with Groups 2-5 (46.9%, 38.3%, 36.1% and 31.2%, respectively, p=0.001). Cox regression analysis showed that poor glycemic control (Group 4 and 5) had lower risk of mortality post-LEA [hazard ratio 0.57 (95% CI 0.35-0.93) and hazard ratio 0.46 (95% CI 0.31-0.69)]; this mortality risk persisted even after adjustment for age and sex but was statistically insignificant. The rate of LEA was greater among poor glycemic control patients; however, the mortality was higher among patients with tight control. Conclusion: The effects of HbA1c on the immediate and long-term LEA outcomes and its therapeutic implications need further investigation.

AbstractOestradiol, an important hormone in follicular development and endometrial receptivity, is closely related to clinical outcomes of fresh in vitro fertilization-embryo transfer (IVF-ET) cycles. A supraphysiologic E2 level is inevitable during controlled ovarian hyper-stimulation (COH), and its effect on the outcome of IVF-ET is controversial. The aim of this retrospective study is to evaluate the association between elevated serum oestradiol (E2) levels on the day of human chorionic gonadotrophin (hCG) administration and neonatal birthweight after IVF-ET cycles. The data of 3659 infertile patients with fresh IVF-ET cycles were analysed retrospectively between August 2009 and February 2017 in First Hospital of Zhengzhou University. Patients were categorized by serum E2 levels on the day of hCG administration into six groups: group 1 (serum E2 levels ≤ 1000 pg/mL, n = 230), group 2 (serum E2 levels between 1001 and 2000 pg/mL, n = 524), group 3 (serum E2 levels between 2001 and 3000 pg/mL, n = 783), group 4 (serum E2 levels between 3001 and 4000 pg/mL, n = 721), group 5 (serum E2 levels between 4001 and 5000 pg/mL, n = 548 ), and group 6 (serum E2 levels > 5000 pg/mL, n = 852). Univariate linear regression was used to evaluate the independent correlation between each factor and outcome index. Multiple logistic regression was used to adjust for confounding factors. The LBW rates were as follows: 3.0% (group 1), 2.9% (group 2), 1.9% (group 3), 2.9% (group 4), 2.9% (group 5), and 2.0% (group 6) (P = 0.629), respectively. There were no statistically significant differences in the incidences of neonatal LBW among the six groups. We did not detect an association between peak serum E2 level during ovarian stimulation and neonatal birthweight after IVF-ET. The results of this retrospective cohort study showed that serum E2 peak levels during ovarian stimulation were not associated with birth weight during IVF cycles. In addition, no association was found between higher E2 levels and increased LBW risk. Our observations suggest that the hyper-oestrogenic milieu during COS does not seem to have adverse effects on the birthweight of offspring after IVF. Although this study provides some reference, the obstetric-related factors were not included due to historical reasons. The impact of the high estrogen environment during COS on the birth weight of IVF offspring still needs future research.

Increased serotonin serum levels have been proposed to play a key role in pulmonary arterial hypertension (PAH) by regulating vessel tone and vascular smooth muscle cell proliferation. An intact serotonin system, which critically depends on a normal function of the serotonin transporter (SERT), is required for the development of experimental pulmonary hypertension in rodents exposed to hypoxia or monocrotaline. While these animal models resemble human PAH only with respect to vascular media remodeling, we hypothesized that SERT is likewise required for the presence of lumen-obliterating intima remodeling, a hallmark of human PAH reproduced in the Sugen hypoxia (SuHx) rat model of severe angioproliferative pulmonary hypertension. Therefore, SERT wild-type (WT) and knockout (KO) rats were exposed to the SuHx protocol. SERT KO rats, while completely lacking SERT, were hemodynamically indistinguishable from WT rats. After exposure to SuHx, similar degrees of severe angioproliferative pulmonary hypertension and right ventricular hypertrophy developed in WT and KO rats (right ventricular systolic pressure 60 vs. 55 mmHg, intima thickness 38 vs. 30%, respectively). In conclusion, despite its implicated importance in PAH, SERT does not play an essential role in the pathogenesis of severe angioobliterative pulmonary hypertension in rats exposed to SuHx.

AbstractTo avoid winter scarcity of fresh goat milk, simple methods of advancing the season of kidding would be commercially valuable. A combination of long-day light treatment followed by melatonin is successful but other aspects of seasonality including coat growth are also reset. To investigate whether effects on breeding season and coat growth can be dissociated, British Saanen dairy goats (no. = 30) were randomly allocated to one of six groups. Control goats were untreated. Goats in the other five groups received 2 months of treatment with 20 h light: 4 h darkness (20L: 4D) and were then given 3 mg melatonin orally at 16.00 hfor 2 months. The treatments started on 11 January (group 1), 29 March (group 2), 14 June (group 3), 30 August (group 4) and 8 November (group 5). Weekly blood samples were taken for the measurement of progesterone to monitor ovarian activity and prolactin. Side patches (10 cm ×10 cm) were clipped monthly from alternate sides and weighed to measure coat growth. The onset of ovarian activity was advanced from a median date of 15 November in controls to 24 May in group 1 (P < 0·01), 16 August in group 2 (P < 0·05) and 18 October in group 3 (? < 0·05). Groups 4 and 5 showed no significant change in the onset of oestrus (median onset dates 8 November and 1 November, respectively). Group 1 goats came into season again with controls in November. In all except group 5, treatment interacted with time to affect significantly the growth of the coat. The pattern of coat growth was most altered (P < 0·001) in groups 1 and 2. This was associated with effects on plasma prolactin concentrations of light stimulation and melatonin suppression. Group 1 goats resynchronized with control goats to show a coat of normal weight in the winter following treatment. Division of milking goat herds into spring and autumn kidding groups is, therefore, a practical possibility, but effects on overall milk yield require study.

A total of 130 barrows and 113 gilts were slaughtered over a range of liveweights from 65.6 to 143.9 kg. These animals were randomly assigned to six different liveweight groups (group 1, less than 79.5 kg; group 2, 79.5 through 93.1 kg; group 3, 93.2 through 106.7 kg; group 4, 106.8 through 120.4 kg; group 5, 120.5 through 134.0 kg; and group 6, 134.1 kg and over) and utilized to evaluate the effects of slaughter weight and sex on palatability and cooking properties. The composite results indicated that the slaughter weight of both barrows and gilts can, from a practical standpoint, be increased to take advantage of potential economic advantages without meaningfully altering cooking losses or palatability attributes.

Summary Background/Introduction There are little data on outcomes of COVID-19 patients with the presence of fever compared to the presence of symptoms. Aim We examined the associations between symptomology, presence of fever and outcomes of a COVID-19 cohort. Design and Methods Between 23 January and 30 April 2020, 554 COVID-19 patients were admitted to a tertiary hospital in Singapore. They were allocated into four groups based on symptomology and fever—Group 1: asymptomatic and afebrile, Group 2: symptomatic but afebrile, Group 3: febrile but asymptomatic and Group 4: symptomatic and febrile. The primary outcomes were intensive care unit (ICU) admissions and mortality. The composite end-point included ICU admissions, mortality or any COVID-19 related end-organ involvement. Results There were differences in ferritin (P=0.003), C-reactive protein (CRP) levels (P&lt;0.001) and lymphopenia (P=0.033) across all groups, with the most favourable biochemical profile in Group 1, and the least in Group 4. Symptomatic groups (Groups 2 and 4) had higher ICU admissions (1.9% and 6.0%, respectively, P=0.003) than asymptomatic groups (Groups 1 and 3). Composite end-point was highest in Group 4 (24.0%), followed by Group 3 (8.6%), Group 2 (4.8%) and Group 1 (2.4%) (P&lt;0.001). The presence of fever (OR 4.096, 95% CI 1.737–9.656, P=0.001) was associated with the composite end-point after adjusting for age, pulse rate, comorbidities, lymphocyte, ferritin and CRP. Presence of symptoms was not associated with the composite end-point. Discussion/Conclusion In this COVID-19 cohort, presence of fever was a predictor of adverse outcomes. This has implications on the management of febrile but asymptomatic COVID-19 patients.
