Published: March 2022

Aims To determine the impact of anesthesia encountered and to optimize the treatment of perioperative pulmonary arterial hypertension (PAH) in an effort to improve perioperative management and reduce complications. Methods We conducted a retrospective analysis of scoliosis patients with PAH who underwent scoliosis surgery. Results During this period, we identified a total of 22 patients. Their mean age was 22.18 ± 2.11 years. 16 PAH patients (72.72%) received PAH-specific treatment. Only Propofol-based TIVA was used intraoperatively. During the procedure, pulmonary artery catheters and PICCO catheters were placed in all patients to monitor intraoperative and postoperative mPAP, MAP, PRVI and SRVI. During tracheal intubation and intraoperative awake testing, mPAP generally tended to increase in all patients. 6 patients (27.27%) received intraoperative PAH-Specific therapy. All patients received oral sildenafil (75-100 mg/d orally), and 9 patients received postoperative oral sildenafil combined with nebulized iloprost (20 μg/d); intravenous treprostinil (2 ng/kg/min started and titrated to 10-17.5 ng/kg/min); or bosentan (250 mg/d) postoperatively. 7 patients (31.82%) reported postoperative complications, including 2 cases of respiratory failure requiring reintubation, 1 case of right heart failure, 2 cases of superficial surgical site infection, 1 case of fluid and electrolyte and acid-base imbalances, 2 cases of pneumonia and 1 case of pulmonary oedema with fluid overload. Two patients developed more than 1 postoperative complication. No in-hospital death occurred. Conclusions The anesthetic management of scoliosis patients with PAH is important task that, like its own surgery, relies on the input of the multidisciplinary team for its success. Close monitoring, optimization of systemic blood pressure, pain control, oxygenation and ventilation, avoidance of exacerbating factors, and the use of vasopressors and pulmonary vasodilators when necessary are essential elements of management.

AbstractBackgroundColocasia gigantea,Caladium bicolorandXanthosoma sagittifoliumare three worldwide famous ornamental and/or vegetable plants in the Araceae family, these species in the subfamily Aroideae are phylogenetically perplexing due to shared interspecific morphological traits and variation.ResultThis study, for the first time ever, assembled and analyzed complete chloroplast genomes ofC. gigantea,C. bicolorandX. sagittifoliumwith genome sizes of 165,906 bp, 153,149 bp and 165,169 bp in length, respectively. The genomes were composed of conserved quadripartite circular structures with a total of 131 annotated genes, including 8 rRNA, 37 tRNA and 86 protein-coding genes. A comparison within Aroideae showed seven protein-coding genes (accD,ndhF,ndhK,rbcL,rpoC1,rpoC2andmatK) linked to environmental adaptation. Phylogenetic analysis confirmed a close relationship ofC. giganteawithC. esculentaandS. colocasiifolia, and theC. bicolorwithX. sagittifolium.Furthermore, three DNA barcodes (atpH-atpI + psaC-ndhE,atpH-atpI + trnS-trnG,atpH-atpI + psaC-ndhE + trnS-trnG) harbored highly variable regions to distinguish species in Aroideae subfamily.ConclusionThese results would be beneficial for species identification, phylogenetic relationship, genetic diversity, and potential of germplasm resources in Aroideae.
Identification of novel alternative splicing associated with mastitis disease in Holstein dairy cows using large gap read mapping
Authors: Asselstine V. , Medrano J. F. , Cánovas A. 
Published: March 2022

Abstract
Background
Mastitis is a very common disease in the dairy industry that producers encounter daily. Transcriptomics, using RNA-Sequencing (RNA - Seq) technology, can be used to study the functional aspect of mastitis resistance to identify animals that have a better immune response to mastitis. When the cow has mastitis, not only genes but also specific mRNA isoforms generated via alternative splicing (AS) could be differentially expressed (DE), leading to the phenotypic variation observed. Therefore, the objective of this study was to use large gap read mapping to identify mRNA isoforms DE between healthy and mastitic milk somatic cell samples (N = 12). These mRNA isoforms were then categorized based on being 1) annotated mRNA isoforms for gene name and length, 2) annotated mRNA isoforms with different transcript length and 3) novel mRNA isoforms of non - annotated genes.

Results
Analysis identified 333 DE transcripts (with at least 2 mRNA isoforms annotated, with at least one being DE) between healthy and mastitic samples corresponding to 303 unique genes. Of these 333 DE transcripts between healthy and mastitic samples, 68 mRNA isoforms are annotated in the bovine genome reference (ARS.UCD.1.2), 249 mRNA isoforms had novel transcript lengths of known genes and 16 were novel transcript lengths of non - annotated genes in the bovine genome reference (ARS.UCD.1.2). Functional analysis including gene ontology, gene network and metabolic pathway analysis was performed on the list of 288 annotated and unique DE mRNA isoforms. In total, 67 significant metabolic pathways were identified including positive regulation of cytokine secretion and immune response. Additionally, numerous DE novel mRNA isoforms showed potential involvement with the immune system or mastitis. Lastly, QTL annotation analysis was performed on coding regions of the DE mRNA isoforms, identifying overlapping QTLs associated with clinical mastitis and somatic cell score.

Conclusion
This study identified novel mRNA isoforms generated via AS that could lead to differences in the immune response of Holstein dairy cows and be potentially implemented in future breeding programs.

Abstract
Background
Chronic diseases are often associated with sexual dysfunction (SD). Little is known about the practice patterns of general practitioners (GPs) regarding sexual care for chronically ill patients. Therefore, the aim of this study was to examine; to what extent GPs discuss SD with chronically ill patients; the barriers that may stop them; and the factors associated with discussing SD.

Methods
A cross-sectional survey using a 58-item questionnaire was sent to 604 Dutch GPs. Descriptive statistics and associations were used for analysis of the data.

Results
Nearly 58% (n = 350) of all GPs approached gave a response and 204 questionnaires were analysable (33.8%). Almost 60% of respondents considered discussing SD with patients important (58.3%, n = 119). During the first consultation, 67.5% (n = 137) of the GPs reported that they never discussed SD. The most important barrier stopping them was lack of time (51.7%, n = 104). The majority (90.2%, n = 184) stated that the GP was responsible for addressing SD; 70.1% (n = 143) indicated that the GP practice somatic care nurse (GPN) was also responsible. Nearly 80% (n = 161) of respondents were unaware of agreements within the practice on accountability for discussing SD. This group discussed SD less often during first and follow-up consults (p = 0.002 and p < 0.001, respectively). Of the respondents, 61.5% (n = 116) felt that they had received insufficient education in SD and 74.6% (n = 150) stated that the subject is seldom discussed during training. Approximately 62% of the GPs (n = 123) wanted to increase their knowledge, preferably through extra training. According to 53.2% of the GPs (n = 107) it was important to improve the knowledge of the GPN. The most frequently mentioned tool that could help improve the conversation about SD was the availability of information brochures for patients (n = 123, 60.3%).

Conclusions
This study indicates that Dutch GPs do not discuss SD with chronically ill patients routinely, mainly due to lack of time. An efficient tool is needed to enable GPs to address SD in a time-saving manner. Increased availability of informational materials, agreements on accountability within GP practices, and extra training for the GPs and GPNs could improve the discussion of SD.

Abstract
Background
Determining the prevalence of pre-treatment HIV drug resistance (PDR) is important to assess the effectiveness of first-line therapies. To determine PDR prevalence in Papua New Guinea (PNG), we conducted a nationally representative survey.

Methods
We used a two-stage cluster sampling method to recruit HIV treatment initiators with and without prior exposure to antiretroviral therapies (ART) in selected clinics. Dried blood spots were collected and tested for PDR.

Results
A total of 315 sequences were available for analysis. The overall PDR prevalence rate was 18.4% (95% CI 13.8–24.3%). The prevalence of PDR to non-nucleoside analog reverse-transcriptase inhibitors (NNRTIs) was 17.8% (95% CI 13.6–23.0%) and of PDR to nucleoside reverse transcriptase inhibitors (NRTIs) was 6.3% (95% CI 1.6–17.1%). The PDR prevalence rate among people reinitiating ART was 42.4% (95% CI 29.1–56.4%).

Conclusions
PNG has a high PDR prevalence rate, especially to NNRTI-based first-line therapies. Our findings suggest that removing NNRTIs as part of first-line treatment is warranted and will lead to improving viral suppression rates in PNG.

Published: March 2022

Abstract
Background
The association between H. pylori (Helicobacter pylori) infection and gastroesophageal reflux disease (GERD) is a complex and confusing subject. The aim of this study was to evaluate the association between helicobacter pylori infection and erosive gastroesophageal reflux disease.

Method
In a cross-sectional study, all patients referred for endoscopy due to dyspepsia were enrolled. The diagnosis of erosive GERD was made by endoscopy. Patients with normal esophagus were selected as comparison group. Random gastric biopsies were taken from all participants to diagnose H. pylori infection.

Result
In total, 1916 patients were included in this study, of whom 45.6% had GERD. The mean age (SD) was 42.95 (16.32). Overall, 1442 (75.3%) patients were positive for H. pylori infection. The frequency of H. pylori infection in mild GERD patients was higher than the severe GERD, but this difference was not significant (P = 0.214). Except for sociodemographic status (P < 0.001), other variables including gender, age, ethnicity, body mass index (BMI), smoking, and presence of hiatus hernia in patients had no significant association with the frequency of H. pylori infection. According to Robust Poisson regression models analysis, the association of H. pylori (PR 1.026; 95% CI 0.990–1.064; P = 0.158) and sociodemographic status were not significantly different between the two groups. But smoking, increased BMI, older age, presence of hiatus hernia, and peptic ulcer diseases were significantly associated with GERD compared with the non-GERD group.

Conclusion
In our results, there was no association between H. pylori infection and erosive GERD. Further studies are recommended.

Published: March 2022

Abstract
Background
Childbirth fear affects 5–40% of all mothers around the world, and there is mounting evidence that it has harmful impacts on women’s health. It could potentially lead pregnant women to feel isolated and unsupported if not identified. But studies addressing this issue are limited in Ethiopia. Therefore, this study was aimed at assessing the magnitude and associated factors of childbirth fear among pregnant women attending antenatal care at public hospitals in West Wollega Zone.

Methods
Facility-based cross-sectional study was conducted among 304 pregnant women selected by systematic random sampling from 20 March to 20 April 2020. A structured interviewer-administered questionnaire was adapted and used to collect data. Data were entered into EpiData version 3.1 and exported to IBM SPSS statistics version 26 for analysis. Descriptive statistics were done to calculate frequencies, mean scores, and standard deviation. Bivariate and multivariable logistic regression was used to identify factors associated with childbirth fear. Variables with p < 0.25 in bivariate analyses were selected for multivariable analysis. Finally, statistical significance was declared at p < 0.05.

Results
Out of the total of 304 participants, 298 completed the interview making the response rate 98%. The overall prevalence of childbirth fear was 28.9% with 95% CI (23.5, 34.2). Mean age of the respondents was 27.60 (SD ± 4.56) years. Having previous pregnancy complications [AOR (95% CI)], [6.949 (2.060 – 23.445), presence of long time during childbirth [AOR (95% CI)], [4.765 (1.161 – 19.564)], presence of episiotomy [AOR (95% CI)], [4.197 (1.107 – 15.917)], low social support [AOR (95% CI)], [.011 (.003 – .050)] were significantly associated with childbirth fear.

Conclusion
Pregnant women in the study area have a significant level of childbirth fear. Previous pregnancy complications, prolonged labor, labor pain, previous perineal tear, and social support were all found to be significantly linked with childbirth fear. This calls for the need to identify and develop interventions for women to reduce childbirth fear during pregnancy.

AbstractBackgroundHypertension has been known to increase the risk of obstetric complications. Recently, the American College of Cardiology endorsed lower thresholds for hypertension as systolic blood pressure of 130-139 mmHg or diastolic blood pressure 80-89 mmHg. However, there is a paucity of information regarding the impact of pre-pregnancy blood pressure on pregnancy outcomes. We aimed to evaluate the effect of pre-pregnancy blood pressure on maternal and neonatal complications.MethodsIn this nationwide, population based study, pregnant women without history of hypertension and pre-pregnancy blood pressure < 140/90 mmHg were enrolled. The primary outcome of composite morbidity was defined as any of the followings: preeclampsia, placental abruption, stillbirth, preterm birth, or low birth weight.ResultsA total of 375,305 pregnant women were included. After adjusting for covariates, the risk of composite morbidity was greater in those with stage I hypertension in comparison with the normotensive group (systolic blood pressure, odds ratio = 1.68, 95% CI: 1.59 – 1.78; diastolic blood pressure, odds ratio = 1.56, 95% CI: 1.42 – 1.72). There was a linear association between pre-pregnancy blood pressure and the primary outcome, with risk maximizing at newly defined stage I hypertension and with risk decreasing at lower blood pressure ranges.Conclusions‘The lower, the better’ phenomenon was still valid for both maternal and neonatal outcomes. Our results suggest that the recent changes in diagnostic thresholds for hypertension may also apply to pregnant women. Therefore, women with stage I hypertension prior to pregnancy should be carefully observed for adverse outcomes.

Published: March 2022

Abstract
Background
Detection of the ROS1 rearrangement is mandatory in patients with advanced or metastatic non-small cell lung cancer (NSCLC) to allow targeted therapy with specific inhibitors. However, in Spanish clinical practice ROS1 determination is not yet fully widespread. The aim of this study is to determine the clinical and economic impact of sequentially testing ROS1 in addition to EGFR and ALK in Spain.

Methods
A joint model (decision-tree and Markov model) was developed to determine the cost-effectiveness of testing ROS1 strategy versus a no-ROS1 testing strategy in Spain. Distribution of ROS1 techniques, rates of testing, positivity, and invalidity of biomarkers included in the analysis (EGFR, ALK, ROS1 and PD-L1) were based on expert opinion and Lungpath real-world database. Treatment allocation depending on the molecular testing results was defined by expert opinion. For each treatment, a 3-states Markov model was developed, where progression-free survival (PFS) and overall survival (OS) curves were parameterized using exponential extrapolations to model transition of patients among health states. Only medical direct costs were included (€ 2021). A lifetime horizon was considered and a discount rate of 3% was applied for both costs and effects. Both deterministic and probabilistic sensitivity analyses were performed to address uncertainty.

Results
A target population of 8755 patients with advanced NSCLC (non-squamous or never smokers squamous) entered the model. Over a lifetime horizon, the ROS1 testing scenario produced additional 157.5 life years and 121.3 quality-adjusted life years (QALYs) compared with no-ROS1 testing scenario. Total direct costs were increased up to € 2,244,737 for ROS1 testing scenario. The incremental cost-utility ratio (ICUR) was 18,514 €/QALY. Robustness of the base-case results were confirmed by the sensitivity analysis.

Conclusions
Our study shows that ROS1 testing in addition to EGFR and ALK is a cost-effective strategy compared to no-ROS1 testing, and it generates more than 120 QALYs in Spain over a lifetime horizon. Despite the low prevalence of ROS1 rearrangements in NSCLC patients, the clinical and economic consequences of ROS1 testing should encourage centers to test all advanced or metastatic NSCLC (non-squamous and never-smoker squamous) patients.
A quantitative comparison of two measures of postpartum depression

Published: March 2022

Abstract
Background
Studies investigating the prevalence and risk factors for postpartum depression (PPD) have used different definitions. Some studies have used a high score on the Edinburgh Postnatal Depression Scale (EPDS) to define PPD, whereas others have used information on antidepressant medication use and/or diagnostic information on treatment for depression at a psychiatric hospital. We wanted to compare results using these two approaches to evaluate to what degree results can be compared. Moreover we wanted to evaluate, whether use of EPDS or PPAT (defined below) leads to identification of different risk factor profiles.

Methods
We identified women who delivered a child between 1 January 2014 and 31 December 2016 in Copenhagen or in one of the municipalities that were part of the Danish Health Visitors’ Child Health Database. The potential risk factors were demographic factors and pregnancy- and obstetrical events. Outcomes of interest were an EPDS score ≥ 13, use of antidepressants (ATC: N06A) and/or a diagnosis of depression (F32) within six months after birth. Use of antidepressants and/or diagnosis of depression will be referred to as postpartum antidepressant treatment (PPAT). Agreement between EPDS ≥ 13 and PPAT was evaluated by the kappa coefficient. Associations between risk factors and the two outcomes (EPDS ≥ 13 and PPAT) were estimated by risk ratios (RR) using log-linear binomial regression. Presence of a systematic difference between RRs based on EPDS ≥ 13 (RREPDS≥13) and PPAT (RRPPAT) was evaluated in a meta-regression approach weighted by inverse-variance and with logarithm of the RRs as outcome.

Results
The estimated PPD prevalence using EPDS ≥ 13 was 3.2% and of PPAT 0.4%. The agreement between the two measures was small (Kappa = 0.08), but their risk factor profile was very similar with no systematic difference between them.

Conclusions
Using the two different methods of case identification produced different prevalence estimates, but a similar risk factor profile. The differences in estimated prevalence and low agreement suggest that the two measures identify different potential PPD cases and using only one of the methods in defining PPD would underestimate PPD prevalence. The similar risk factor profile suggests that the considered risk factors are involved in the general development of PPD.

AbstractBackgroundAdequate good quality of sleep is essential for physical fitness during pregnancy as well as being a depressive symptoms-free mind. However, there is little evidence of the relationship between depressive symptoms and poor sleep quality among pregnant women in Bangladesh. This study aimed to find the association between depressive symptoms and poor sleep quality among pregnant women in northern rural Bangladesh.MethodsA community-based cross-sectional study was carried out from May 2021 to June 2021 among 481 pregnant women tested positive in the pregnancy test of Jaldhaka and Dimla Upazila of Nilphamari district, Rangpur Division. Data were collected with a structured questionnaire including socio-demographic conditions, sleep quality, and depressive symptoms, comprising the Pittsburgh Sleep Quality Index (PSQI) and the Patient Health Questionnaire- 9 (PHQ-9).Results8.94% of the women had depressive symptoms, whereas 38.88% of the participants were bad sleepers. However, women who had depressive symptoms [Adjusted odds ratio (AOR) = 2.55; 95% CI 1.33-4.9] and educational qualifications above 10 years [AOR = 0.60; 95% CI: 0.39-0.92] were associated with poor sleep quality.ConclusionsA higher percentage of pregnant women had poor sleep quality, whereas depressive symptoms and academic background of the participants were significantly associated with poor sleep quality. Ensuring adequate sleep time and better quality could be helpful to prevent depressive symptoms.
