Abstract
Background
World Health Organization recommends exclusive breastfeeding (EBF) for 6 months with maternal active antiretroviral therapy (ART) to prevent mother-to-child transmission (PMTCT) of HIV. However, EBF in low resource settings remains low. We explored perspectives of EBF by HIV-infected mothers and health care workers in Busia County with a high prevalence of HIV to understand factors influencing the practice.

Methods
A mixed methods cross-sectional survey using concurrent quantitative and qualitative data collection methods was conducted at PMTCT clinics. Data on socio-demography, young infant feeding practices, maternal and infant health was collected between February 2013 and August 2015 from 371 purposively sampled HIV-infected mother-infant dyads using a semi-structured questionnaire. Focus group discussions with mothers, in-depth interviews and passive observation of health care workers during interaction with mothers were conducted. Significance of difference between mothers practicing EBF or not was tested by Chi-square and Fisher’s exact tests setting significance level at 5%. Qualitative data was coded and content analyzed to generate themes.

Results
Three hundred and forty-nine (94%) mothers practiced EBF. Maternal comprehension of EBF to PMTCT of HIV influenced choice and practice of EBF (P value = 0.019 and < 0.001 respectively). Health care workers emphasized adherence to ART and offered nutritional supplementation during EBF. Health care workers’ nutritional counseling in the context of maternal HIV was poor. Mentor mothers shared their experiences with mothers and offered live case demonstrations of their successfully EBF, healthy and HIV-uninfected children. The main threats to EBF were teenage motherhood, low maternal education and working during EBF.

Conclusions
EBF among HIV-infected mothers in Busia County, Kenya was high. Health education and counselling by health care workers, maternal comprehension of ART adherence to PMTCT of HIV, nutritional supplementation and mentor mothers’ peer counseling using live case demonstrations of HIV-uninfected EBF children promoted and sustained practice of EBF for 6 months. Teenage motherhood, low maternal education and having to work threatened EBF,

Abstract
Purpose
To rebuild a model of the pelvis and effectively simulate the trajectory of modified sacroiliac screws, we measured the parameters of each screw and screw channel and assessed the safety and feasibility of the parameters in adults.

Method and materials
One hundred (50 males and 50 females) normal adult pelvic computed tomography (CT) images were randomly selected and imported into Mimics software to rebuild the three-dimensional pelvis model. In these models, each ideal channel of modified screws was simulated, and then we obtained the precise parameters of screws and channels using Mimics and Three-matic software.

Results
The results of the comparison (right vs. left) showed that there were no significant differences in any of the angles, radius or M1SI parameters (the first modified sacroiliac). However, one parameter (BS) of M2SI (the second modified sacroiliac), two parameters (AP and BS) of M3SI (the third modified sacroiliac), and three parameters (AP, BS, L) of M4SI (the fourth modified sacroiliac) were statistically significant (P < 0.05). The result of comparison (between genders) showed that there were no significant differences in M1SI and M2SI; in contrast, the radius, length and the α angle of M3SI and M4SI were significantly different between genders (P < 0.05), and the radius of M4SI required special attention. If the radius of the limiting screw channel was > 3.50 mm, 52 cases (52%, 24 males and 28 females) could not complete the M4SI screw placement among 100 samples. If the radius of the limiting screw channel was > 3.0 mm, a total of 10 cases (10%, 2 males and 8 females) could not complete the M4SI screw placement.

Conclusion
Through the measurement of 100 healthy adult real three-dimensional pelvic models, we obtained the parameters of each modified sacroiliac screw and measured the three angles of each screw based on international coordinates for the first time, which can instruct clinical application.

Abstract
Background
For stage I non-small cell lung cancer (NSCLC), lobectomy and segmentectomy are still controversial operations. Extended segmentectomy was proposed to make larger safe margins than segmentectomy. Image-guided video-assisted thoracoscopic surgery (iVATS) is useful to accomplish extended segmentectomy. We aimed to compare the effects of iVATS extended segmentectomy to the effects of traditional segmentectomy for stage I NSCLC.

Methods
This study is a retrospective analysis in a single institute. Patients with stage I NSCLC who received segmentectomy between January 2017 and September 2020 were included. Patients were distributed to iVATS extended segmentectomy (group A), and traditional segmentectomy (group B). The impacts of the different surgical methods on resection margin were assessed.

Results
There were 116 patients enrolled in this study. Sixty-two patients distributed in group A, and the other 54 patients in group B. The resection margin to a staple line was 17.94 mm in group A versus 14.15 mm in group B, p = 0.037. The margin/tumor diameter ratio was 2.08 in group A versus 1.39 in group B, p = 0.003. The enough margin rate was 75.81% and 57.41%, respectively, for group A and group B. The subgroup analysis of iVATS extended segmentectomy showed that T1a lesions had larger margin distances than did T1b lesions (19.85 mm vs. 14.83 mm, p = 0.026).

Conclusions
The iVATS extended segmentectomy can provide more resection margin than traditional segmentectomy. Segmentectomy is more suitable to perform when the nodule’s diameter is less than 10 mm.
Thoracic endovascular aortic repair with a right thoracotomy approach
Authors: Tanioka Hideki , Shibukawa Takanori , Iwata Keiji 
Published: March 2022

Abstract
Background
The common femoral artery is usually the preferred access route for thoracic endovascular aortic repair (TEVAR). However, if access from the common femoral artery is challenging, other routes must be considered. We report a case of TEVAR performed by approaching the descending thoracic aorta with a right thoracotomy and using the descending thoracic aorta as an access route.

Case presentation
A 70-year-old female was diagnosed with a descending thoracic aortic aneurysm (65 mm in diameter), a thoracoabdominal aneurysm (54 mm in diameter), and an abdominal aortic aneurysm (49 mm in diameter). Since the patient had severe chronic obstructive pulmonary disease, one-stage replacement of the thoracoabdominal aortic aneurysm was contraindicated and TEVAR on the descending aorta was selected. A strong tortuous section of the aorta—from the descending aorta to the abdominal aorta—hampered endovascular access to the site from the common femoral artery. A TEVAR approach from the abdominal aorta was also considered; however, an abdominal aortic aneurysm and a transverse colon loop stoma from an earlier surgery presented challenges to this technique. We chose to access the descending thoracic aorta with a thoracotomy from the right 6th intercostal space for TEVAR, because the access route that is not affected by the meandering of the aorta is considered to be the descending aorta with a right thoracotomy. The patient’s postoperative course was uneventful after the stent graft was placed. No complications were detected with postoperative contrast-enhanced computed tomography (CT).

Conclusions
Our findings suggest that TEVAR can be performed by approaching the descending aorta from a right thoracotomy, if variations of vascular anatomy interfere with the more commonly used femoral artery approach.

AbstractBackgroundNeurodegeneration with brain iron accumulation describes a group of rare heterogeneous progressive neurodegenerative disorders characterized by excessive iron accumulation in the basal ganglia region. Pantothenate kinase-associated neurodegeneration (PKAN) is a major form of this disease.ResultsA total of 7 unrelated patients were diagnosed with PKAN in a single tertiary center from August 2009 to February 2018. Ten variants inPANK2including three novel sequence variants and one large exonic deletion were detected. Sequencing of the breakpoint was performed to predict the mechanism of large deletion and AluSx3 and AluSz6 were found with approximately 97.3% sequence homology.ConclusionThe findings support the disease-causing role ofPANK2and indicate the possibility that exonic deletion ofPANK2found in PKAN is mediated throughAlu-mediated homologous recombination.

AbstractBackgroundTo investigate the clinical manifestations, visual outcomes and optical coherence tomographic (OCT) features of patients with posterior sympathetic ophthalmia (PSO).MethodsWe performed a retrospective review of 48 patients diagnosed with PSO between January 2013 and December 2019. We compared the clinical and OCT features among different clinical types of PSO.ResultsPSO could be classified into two types according to whether the fundus exhibited serous retinal detachment (SRD) or multifocal choroiditis (MFC). There were 41 patients (85.4%) with SRD and 7 patients (14.6%) with MFC. The latent period of patients with MFC was significantly longer than that of patients with SRD (P = 0.002). The final visual acuity of patients with MFC was significantly worse than that of patients with SRD (P = 0.0001). In patients with acute SRD, OCT revealed that the mean height of retinal detachment in the fovea was 528.8 ± 437.5 μm. After treatment, the retina reattached in all patients and the band structures of the outer retina were restored in most patients (92.7%). In patients with acute MFC, the OCT images revealed inflammatory lesions on the retinal pigment epithelium layer. After treatment, the OCT images showed hyperreflective fibrosis of the lesions and loss of the outer retinal band structures in all patients.ConclusionsWe found that PSO could be classified according to the presence of SRD or MFC. The visual prognosis differed significantly between these types of PSO. OCT imaging is useful for clinical classification and monitoring of retinal changes after treatment.

Abstract
Background
Diagnosis of mature-onset diabetes of the young (MODY), a non-autoimmune monogenic form of diabetes mellitus, is confirmed by genetic testing. However, a positive genetic diagnosis is achieved in only around 50% of patients with clinical characteristics of this disease.

Results
We evaluated the diagnostic utility of transcriptomic analysis in patients with clinical suspicion of MODY but a negative genetic diagnosis. Using Nanostring nCounter technology, we conducted transcriptomic analysis of 19 MODY-associated genes in peripheral blood samples from 19 patients and 8 healthy controls. Normalized gene expression was compared between patients and controls and correlated with each patient’s biochemical and clinical variables. Z-scores were calculated to identify significant changes in gene expression in patients versus controls. Only 7 of the genes analyzed were detected in peripheral blood. HADH expression was significantly lower in patients versus controls. Among patients with suspected MODY, GLIS3 expression was higher in obese versus normal-weight patients, and in patients aged < 25 versus > 25 years at diabetes onset. Significant alteration with respect to controls of any gene was observed in 57.9% of patients.

Conclusions
Although blood does not seem to be a suitable sample for transcriptomic analysis of patients with suspected MODY, in our study, we detected expression alterations in some of the genes studied in almost 58% of patients. That opens the door for future studies that can clarify the molecular cause of the clinic of these patients and thus be able to maintain a more specific follow-up and treatment in each case.
Perfect match: mTOR inhibitors and tuberous sclerosis complex

Published: March 2022

AbstractTuberous sclerosis complex (TSC) is an autosomal dominant syndrome that presents with diverse and complex clinical features and involves multiple human systems. TSC-related neurological abnormalities and organ dysfunction greatly affect the quality of life and can even result in death in patients with TSC. It is widely accepted that most TSC-related clinical manifestations are associated with hyperactivation of the mammalian target of rapamycin (mTOR) pathway caused by loss‑of‑function mutations in TSC1 or TSC2. Remarkable progress in basic and translational research has led to encouraging clinical advances. Although mTOR inhibitors (rapamycin/everolimus) demonstrate great potential in TSC management, two major concerns hamper their generalized application. One is the frequent manifestation of adverse events, such as stomatitis, infections, and menstrual disorders; and the other is the poor response in certain patients. Thus, indicators are required to effectively predict the efficacy of mTOR inhibitors. Herein, we have summarized the current utilization of mTOR inhibitors in the treatment of TSC and focused on their efficacy and safety, in an attempt to provide a reference to guide the treatment of TSC.

Published: March 2022

Abstract
Background
Men’s depression, alcohol use, and family problems commonly co-occur to create of cluster of mental health problems. Yet, few treatments exist to address these problems, especially in low and middle-income countries (LMICs). This paper describes the development and initial feasibility and acceptability of a novel task-shifted intervention to address this cluster of men’s mental health problems with a focus on engaging and retaining men in treatment.

Methods
The intervention, Learn, Engage, Act, Dedicate (LEAD), is based in behavioral activation blended with motivational interviewing and was pilot tested in Kenya. To develop LEAD, we engaged in a community-engaged multi-step, collaborative process with local Kenyan stakeholders. LEAD was piloted with nine fathers reporting problem drinking. To assess initial feasibility and acceptability, recruitment and participation were tracked and descriptive statistics were generated given engagement of men was key for proof of concept. Semi-structured interviews were conducted with participants and analyzed using thematic content analysis.

Results
The development process resulted in a weekly 5-session intervention rooted in behavioral activation, motivational interviewing, and masculinity discussion strategies. These approaches were combined and adapted to fit contextually salient constructs, such as the importance of the man as provider, and streamlined for lay providers. Feasibility and acceptability results were promising with high attendance, acceptability of delivery and intervention content, and perceived intervention helpfulness.

Conclusion
Results describe an acceptable task-shifted treatment that may engage men in care and addresses a cluster of common mental health problems among men in ways that consider social determinants like masculinity. Findings set the stage for a larger trial.

Published: March 2022

Abstract
Background
Stigma is a social phenomenon known to have a negative impact on the lives of people living with HIV (PLWH). However, defining HIV-related stigma (HRS) is difficult because of the intersection it has with structural inequalities, and cultural differences, discrimination by health care providers that measure stigma among PLWH. HIV/AIDS has been characterized as a traumatic experience and PLWH may experience stigma which can cause negative mental health disorders and experiences, including emotional distress, shame, depression, anxiety, suicidal ideation. A systematic review of the evidence on the mental disorders of PLWH is currently lacking. This study aimed to analyze the association between HRS and social support, alcohol use disorders and mental health disorders and experiences (depression, anxiety, and suicidal ideation) among PLWH.

Methods
In accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) this study searched PubMed, Scopus, Web of sciences, PsycInfo, SciELO and Cochrane library electronic databases to identify publications between January 1992 and August 2020 that discussed social support, alcohol use disorders, mental health disorders and experiences (i.e., depression and anxiety and suicidal ideation) associated with HRS. Pooled Odds Ratios (ORs) were utilized at a 95% confidence level, and as sampling methods differed between articles pooled estimates used a random effects model.

Results
Twenty-two studies with 9548 participants met the eligibility criteria. No association was observed between HRS and alcohol use disorders. PLWH who had higher levels of social supports were less likely to report HRS. Participants who had been diagnosed with anxiety were 1.89 times more likely to report HRS, while those diagnosed with depression were 1.61 times more. Respondents who reported suicidal ideation also were 1.83 times more likely to report HRS.

Conclusions
This meta-analysis supports that HRS has a detrimental association with anxiety, depression and suicidal ideation, but social support protects again HRS in PLWH. Applying interventions which focus on the mental health disorders of PLWH may decrease HRS. Provision of social support by practitioners, combined with mental health treatment and assessments, and designing methods to identify stigma at different stages of illness are warranted.
Circadian rhythms and cancers: the intrinsic links and therapeutic potentials

Published: March 2022

AbstractThe circadian rhythm is an evolutionarily conserved time-keeping system that comprises a wide variety of processes including sleep–wake cycles, eating–fasting cycles, and activity–rest cycles, coordinating the behavior and physiology of all organs for whole-body homeostasis. Acute disruption of circadian rhythm may lead to transient discomfort, whereas long-term irregular circadian rhythm will result in the dysfunction of the organism, therefore increasing the risks of numerous diseases especially cancers. Indeed, both epidemiological and experimental evidence has demonstrated the intrinsic link between dysregulated circadian rhythm and cancer. Accordingly, a rapidly increasing understanding of the molecular mechanisms of circadian rhythms is opening new options for cancer therapy, possibly by modulating the circadian clock. In this review, we first describe the general regulators of circadian rhythms and their functions on cancer. In addition, we provide insights into the mechanisms underlying how several types of disruption of the circadian rhythm (including sleep–wake, eating–fasting, and activity–rest) can drive cancer progression, which may expand our understanding of cancer development from the clock perspective. Moreover, we also summarize the potential applications of modulating circadian rhythms for cancer treatment, which may provide an optional therapeutic strategy for cancer patients.
