Published: January 2022

Background

Parkinson’s disease (PD) and dementia with Lewy bodies (DLB) are common age-related neurodegenerative diseases comprising Lewy body spectrum disorders associated with cortical and subcortical Lewy body pathology. Over 30% of PD patients develop PD dementia (PDD), which describes dementia arising in the context of established idiopathic PD. Furthermore, Lewy bodies frequently accompany the amyloid plaque and neurofibrillary tangle pathology of Alzheimer’s disease (AD), where they are observed in the amygdala of approximately 60% of sporadic and familial AD. While PDD and DLB share similar pathological substrates, they differ in the temporal onset of motor and cognitive symptoms; however, protein markers to distinguish them are still lacking.

Methods

Here, we systematically studied a series of AD and PD pathogenesis markers, as well as mitochondria, mitophagy, and neuroinflammation-related indicators, in the substantia nigra (SN), temporal cortex (TC), and caudate and putamen (CP) regions of human post-mortem brain samples from individuals with PDD and DLB and condition-matched controls.

Results

We found that p-APPT668 (TC), α-synuclein (CP), and LC3II (CP) are all increased while the tyrosine hydroxylase (TH) (CP) is decreased in both PDD and DLB compared to control. Also, the levels of Aβ42 and DD2R, IBA1, and p-LRRK2S935 are all elevated in PDD compared to control. Interestingly, protein levels of p-TauS199/202 in CP and DD2R, DRP1, and VPS35 in TC are all increased in PDD compared to DLB.

Conclusions

Together, our comprehensive and systematic study identified a set of signature proteins that will help to understand the pathology and etiology of PDD and DLB at the molecular level.
Melatonin increases growth and salt tolerance of Limonium bicolor by improving photosynthetic and antioxidant capacity
Authors: Li Junpeng , Liu Yun , Zhang Mingjing , Xu Hualing , Ning Kai , Wang Baoshan , Chen Min
Published: January 2022

Background

Soil salinization is becoming an increasingly serious problem worldwide, resulting in cultivated land loss and desertification, as well as having a serious impact on agriculture and the economy. The indoleamine melatonin (N-acetyl-5-methoxytryptamine) has a wide array of biological roles in plants, including acting as an auxin analog and an antioxidant. Previous studies have shown that exogenous melatonin application alleviates the salt-induced growth inhibition in non-halophyte plants; however, to our knowledge, melatonin effects have not been examined on halophytes, and it is unclear whether melatonin provides similar protection to salt-exposed halophytic plants.

Results

We exposed the halophyte Limonium bicolor to salt stress (300 mM) and concomitantly treated the plants with 5 μM melatonin to examine the effect of melatonin on salt tolerance. Exogenous melatonin treatment promoted the growth of L. bicolor under salt stress, as reflected by increasing its fresh weight and leaf area. This increased growth was caused by an increase in net photosynthetic rate and water use efficiency. Treatment of salt-stressed L. bicolor seedlings with 5 μM melatonin also enhanced the activities of antioxidants (superoxide dismutase [SOD], peroxidase [POD], catalase [CAT], and ascorbate peroxidase [APX]), while significantly decreasing the contents of hydrogen peroxide (H2O2), superoxide anion (O2•−), and malondialdehyde (MDA). To screen for L. bicolor genes involved in the above physiological processes, high-throughput RNA sequencing was conducted. A gene ontology enrichment analysis indicated that genes related to photosynthesis, reactive oxygen species scavenging, the auxin-dependent signaling pathway and mitogen-activated protein kinase (MAPK) were highly expressed under melatonin treatment. These data indicated that melatonin improved photosynthesis, decreased reactive oxygen species (ROS) and activated MAPK-mediated antioxidant responses, triggering a downstream MAPK cascade that upregulated the expression of antioxidant-related genes. Thus, melatonin improves the salt tolerance of L. bicolor by increasing photosynthesis and improving cellular redox homeostasis under salt stress.

Conclusions

Our results showed that melatonin can upregulate the expression of genes related to photosynthesis, reactive oxygen species scavenging and mitogen-activated protein kinase (MAPK) of L. bicolor under salt stress, which can improve photosynthesis and antioxidant enzyme activities. Thus melatonin can promote the growth of the species and maintain the homeostasis of reactive oxygen species to alleviate salt stress.

Published: January 2022

Background

Among different common types of cancer, gastric cancer (GC) is a worldwide health priority in both developing and developed countries. The aim of this study was to map the distribution of incident cases of GC in Iran to provide a geographical presentation of the incidence of the disease.

Methods

This study used the Iranian National Cancer Registry (INCR) data from 2004 to 2014. We calculated the crude and age-standardized incidence rates of GC for each province and also defined the frequency distribution of different types and locations of GC by the provinces.

Results

According to the results of the present study, the patients were predominantly male 49,907 (70.0%) and the most prevalent type of tumour was A1 (almost 96.4%) and C3‌ (2.0%). Also, a significant difference was observed between males and females in the distribution of the types of tumour (P < 0.001). In addition, a comparison of the distribution of the types of GC in Iran suggested that a significant difference exists between the provinces (P < 0.001). A significant difference was observed when the distribution of the location of GC tumors was compared between males and females and provinces (P < 0.001). Accordingly, pylori and cardia are the most common location of GC cancer among the study population (28.1% and 31.3% respectively).

Conclusions

The results of the current study suggested a higher rate of GC incidence in Iran when compared to the global figure in both females and males. Our study also revealed significant disparities between provinces with regard to the distribution of types, and location of GC. This may suggest involving different factors in GC in different parts of Iran. Further studies are needed to better understand the epidemiology and etiology of the disease in Iran.

Published: January 2022

Background

Concerns regarding potential toxicity and drug-drug interactions during long-term treatment with three-drug active antiretroviral therapy (ART) regimens have been attracting increasing attention. We aimed to evaluate the efficacy and safety of dolutegravir (DTG) plus lamivudine (3TC) in ART-naive adults in China.

Methods

This prospective observational cohort study enrolled HIV-naive inpatients treated with DTG + 3TC (2DR arm) or efavirenz (EFV) plus tenofovir disoproxil fumarate (TDF) and 3TC (3DR arm). There were no limits on baseline viral load. Inflammatory biomarkers were also investigated in the 2DR arm.

Results

Between September 2019 and January 2020, 27 patients treated with DTG + 3TC and 28 patients treated with EFV + TDF + 3TC were enrolled in the study. At week 12, the proportion of patients with viral loads < 50 copies/mL in the 2DR arm was 81.5% (22/27) compared with 53.6% (15/28) in the 3DR arm (p < 0.01). At week 24, the proportion of patients with viral loads < 50 copies/mL in the 2DR arm was 100% (26/26) compared with 83.3% (20/24) in the 3DR arm (p < 0.05). Mean changes in CD4 cell counts from baseline at week 12 were 125.46 cells/µL in the 2DR arm and 41.20 cells/µL in the 3DR arm (p < 0.05). Mean changes in CD4 cell counts from baseline at week 24 were 209.68 cells/µL in the 2DR arm and 73.28 cells/µL in the 3DR arm (p < 0.05).

Conclusions

DTG + 3TC achieved virologic suppression more rapidly than EFV + TDF + 3TC after 12 and 24 weeks. DTG + 3TC could represent an optimal regimen for advanced patients.

Authors: Zhang Cui , Zong Yanmei , Wang Zhe , Wang Li , Li Ying , Yang Yuejie
Published: January 2022

Background

To identify risk factors associated with the prognosis of pertussis in infants (< 12 months).

Methods

A retrospective study on infants hospitalized with pertussis January 2017 to June 2019. The infants were divided into two groups according to the severity of disease: severe pertussis and non-severe pertussis groups. We collected all case data from medical records including socio-demographics, clinical manifestations, and auxiliary examinations. Univariate analysis and Logistic regression were used.

Results

Finally, a total of 84 infants with severe pertussis and 586 infants with non-severe pertussis were admitted. The data of 75% of the cases (severe pertussis group, n = 63; non-severe pertussis group, n = 189) were randomly selected for univariate and multivariate logistic regression analysis. The results showed rural area [P = 0.002, OR = 6.831, 95% CI (2.013–23.175)], hospital stay (days) [P = 0.002, OR = 1.304, 95% CI (1.107–1.536)], fever [P = 0.040, OR = 2.965, 95% CI (1.050–8.375)], cyanosis [P = 0.008, OR = 3.799, 95% CI (1.419–10.174)], pulmonary rales [P = 0.021, OR = 4.022, 95% CI (1.228–13.168)], breathing heavily [P = 0.001, OR = 58.811, 95% CI (5.503–628.507)] and abnormal liver function [P < 0.001, OR = 9.164, 95% CI (2.840–29.565)] were independent risk factors, and higher birth weight [P = 0.006, OR = 0.380, 95% CI (0.191–0.755)] was protective factor for severe pertussis in infants. The sensitivity and specificity of logistic regression model for remaining 25% data of severe group and common group were 76.2% and 81.0%, respectively, and the consistency rate was 79.8%.

Conclusions

The findings indicated risk factor prediction models may be useful for the early identification of severe pertussis in infants.
Intramedullary parasite eggs, latent for three decades, mimicking acute transverse myelitis
Authors: Kim Hyo-jeong , Kim Se-Hoon , Jeong Hoi-seon , Kim Bum-Joon
Published: January 2022

Background

Intramedullary parasitic infection is extremely uncommon, and clinical presentation of Brown-Sequard syndrome is even rarer.

Case presentation

The authors report a case involving a 57-year-old woman with Brown-Sequard syndrome, in whom magnetic resonance imaging and clinical and epidemiological features were similar to those of acute transverse myelitis. Myelotomy suggested inflammation caused by latent parasite eggs in the spinal cord. Antiparasitic and steroid therapies were administered postoperatively. To the author’s knowledge, this is the first report to describe a surgical experience for Taenia solium eggs in the spinal cord.

Conclusion

Intramedullary parasitic infection is a diagnostic challenge that requires careful discrimination from other diseases. If parasite infection is suspected in a progressively deteriorating patient, myelotomy should be considered for rapid and accurate treatment.
Cumulative childhood trauma and complex psychiatric symptoms in pregnant women and expecting men
Authors: Garon-Bissonnette Julia , Bolduc Marie-Ève Grisé , Lemieux Roxanne , Berthelot Nicolas
Published: January 2022

Background

Women and men having been exposed to childhood trauma would be at high risk of various mental health symptoms while awaiting a child. This study aimed to evaluate the association between cumulative childhood trauma and the accumulation of symptoms belonging to different psychiatric problems in pregnant women and expecting men.

Methods

We first examined prevalence rates of childhood trauma across our samples of 2853 pregnant women and 561 expecting men from the community. Second, we evaluated the association between cumulative childhood trauma and symptom complexity (i.e., the simultaneous presentation of symptoms belonging to multiple psychiatric problems) using subsamples of 1779 pregnant women and 118 expecting men. Participants completed self-reported measures of trauma (Childhood Trauma Questionnaire) and psychiatric symptoms (PTSD Checklist for DSM-5; Kessler Psychological Distress Scale; State-Trait Anger Expression Inventory-2; Self and Interpersonal Functioning Scale).

Results

Trauma was more frequent in pregnant women than in expecting men and in participants reporting sociodemographic risk factors than in those not reporting any. A dose-response relationship was observed between the number of different traumas reported by pregnant women and expecting men and the complexity of their psychiatric symptoms, even when controlling for the variance explained by other risk factors. Women having been exposed to cumulative childhood trauma were 4.95 times more at risk of presenting comorbid psychiatric problems during pregnancy than non-exposed women.

Conclusions

Childhood trauma is frequent in the general population of pregnant women and expecting men and is associated with symptom complexity during the antenatal period. These findings call for delivering and evaluating innovative trauma-informed antenatal programs to support mental health and adaptation to parenthood in adults having been exposed to childhood trauma.
Comparison of accommodation and accommodative micro-fluctuation after implantable collamer lens and LASIK surgery for myopia
Authors: Li Li , Zhang Bo , Wang Zheng
Published: January 2022

Background

To longitudinally analyze and compare the accommodative micro-fluctuation (MFs) and accommodative function between myopic patients after implantable collamer lens (ICL) implantation and laser in situ keratomileusis (LASIK).

Methods

Patients with good corrected visual acuity (20/20 or better) and underwent ICL (V4c) and LASIK for myopic-correction (ranging from − 3.50 to − 8.50 D) were recruited. Refraction, amplitude of accommodation (AMP), accommodative lag, higher-order aberration (HOA), and MFs were recorded before surgery and 1 and 3 months after surgery. The ACOMEREF automatic refractor was used to measure the high-frequency component (HFC) of the MFs, which suggested tension of the ciliary muscle.

Results

The study comprised 120 eyes. At 3 months after surgery, the manifest refractive spherical equivalent of the ICL and LASIK groups were − 0.11 and − 0.09 D, respectively (p = 0.46). HFC values were significantly higher at 1 month (p = 0.03) and 3 months postoperatively (p = 0.03) in the ICL group compared to that in the LASIK group. The ocular HOA of the ICL group was 1.08 ± 0.43 μm, which was lower than the LASIK group 1.45 ± 0.54 μm (p = 0.01). No significant differences in AMP and accommodative lag between groups were noted at 3 months postoperatively. There was a positive correlation between HFC and vault of the ICL lens (r2 = 0.14, p = 0.005). There were no correlations between HFC and ocular HOA and postoperative MRSE in the two groups (all p>0.05).

Conclusions

The HFC increased significantly after an early period of ICL implantation compared to laser in situ keratomileusis for myopic correction, which indicated increased tension of the ciliary muscle, and had a positive correlation on the vault of the ICL lens; However, studies with longer follow-up time and more structural evaluation are needed.

Authors: Sun Chao , Chen Xiaofan , Huang Yanming , Zou Huan , Fan Wei , Yang Mei , Yuan Rongdi
Published: January 2022

Background

To study the effects of aerobic exercise (AE) on tear secretion and tear film stability in dry eye patients.

Methods

This study consisted of two parts, each part included 3 groups, namely dry eye without AE group, dry eye with AE group and pre-clinical dry eye with AE group. In part 1, we studied the variations of Schirmer I test and six tear compositions before and after AE (34 eyes in each group). In part 2, we studied the variations of tear meniscus height, first and average non-invasive tear breakup time (F-NITBUT and A-NITBUT), lipid layer thickness, number of incomplete and complete blinks, partial blink rate (PBR) and visual acuity before and after AE (30 eyes in each group).

Results

In dry eye with AE group, Schirmer I test at 0 min after AE increased significantly compared to baseline (P < 0.001), the oxidative stress marker 8-hydroxy-2′-deoxyguanosine after AE decreased significantly compared to baseline (P = 0.035, P = 0.045), F-NITBUT and A-NITBUT after AE prolonged significantly compared to baseline (P < 0.001, P = 0.007, P = 0.036; P < 0.001, P = 0.001, P = 0.044), number of incomplete blinks and PBR at 10 min after AE decreased significantly compared to baseline (P < 0.001; P < 0.001) while number of complete blinks increased significantly (P < 0.001). Besides, significant differences were also found between dry eye with AE group and dry eye without AE group at all above corresponding time point (P < 0.05).

Conclusion

AE promotes tear secretion and improves tear film stability in dry eye patients. AE may be a potential treatment for dry eye.

Containment and therapeutic relationships in acute psychiatric care spaces: the symbolic dimensions of doors
Authors: Missouridou Evdokia , Fradelos Evangelos C. , Kritsiotakis Emmanouel , Mangoulia Polyxeni , Segredou Eirini , Papathanasiou Ioanna V.
Published: January 2022

Background

There is an increasing trend of door locking practices in acute psychiatric care. The aim of the present study was to illuminate the symbolic dimensions of doors in Greek mental health nurses’ experiences of open and locked working spaces.

Results

A sequential mixed-method designexplored the experiences of nurses working in both open and locked psychiatric acute care units. Participants experiences revealed four types of doors related to the quality of recovery-oriented care: (a) the open door, (b) the invisible door, (c) the restraining door, and (d) the revolving door. Open doors and permeable spacesgenerated trust and facilitated the diffusion of tension and the necessary perception of feeling safe in order to be involved in therapeutic engagement. When the locked unit was experienced as a caring environment, the locked doors appeared to be “invisible”. The restraining doors symbolized loss of control, social distance and stigma echoing the consequences of restrictingpeople’s crucial control over spaceduring the COVID-19 pandemicin relation toviolence within families, groups and communities. The revolving door (service users’ abscondence/re-admission) symbolised the rejection of the offered therapeutic environment and was a source of indignation and compassion fatigue in both open and locked spaces attributed to internal structural acute care characteristics (limited staffing levels, support, resources and activities for service users) as well as ‘locked doors’ in the community (limited or no care continuity and stigma).

Conclusions

The impact of COVID-19 restrictions on people’s crucial control of space provides an impetus for erecting barriers masked by the veil of habit and reconsidering the impact of the simple act of leaving the door open/locked to allow both psychiatric acute care unit staff and service users to reach their potential.
The usefulness of virtual, augmented, and mixed reality technologies in the diagnosis and treatment of attention deficit hyperactivity disorder in children: an overview of relevant studies
Authors: Goharinejad Saeideh , Goharinejad Samira , Hajesmaeel-Gohari Sadrieh , Bahaadinbeigy Kambiz
Published: January 2022

Background

Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental condition characterized by attention problems, excessive physical activity, and impulsivity. ADHD affects not only the patients but also their families. The development and use of technologies such as virtual reality (VR), augmented reality (AR), and mixed reality (MR) for ADHD has increased over recent years. However, little is known about their potential usefulness. This overview aimed to clarify the current knowledge about the use of these three innovative technologies for the diagnosis and treatment of children with ADHD.

Methods

This overview was conducted using the PubMed, Web of Science, and Scopus databases until January 24th, 2021. The following descriptive information was compiled from the identified studies: country, year of publication, sample size, study design, ADHD diagnosis methods, applied technology, hardware equipment, clinical target, and main findings.

Results

The initial database searches yielded 409 articles, but 103 were removed as duplicates. Eventually, 30 eligible studies remained for analysis, the majority of which were case-control (n = 22, 73%). Regarding the applied technology/hardware equipment, VR (n = 27; 90%), head-mounted displays (n = 19, 63%), VR-based continuous performance tests (VR-CPT) (n = 21, 70%) were most frequently used. Most studies (n = 21, 70%) used the DSM criteria for the diagnosis of childhood ADHD. They primarily evaluated the utility of these technologies in assessing ADHD symptoms (n = 10, 33%) and improving the ADHD diagnostic process (n = 7, 23%).

Conclusion

This comprehensive overview evaluated the studies on the use of VR, AR, and MR technologies for children with ADHD. These technologies seem to be promising tools for improving the diagnosis and management of ADHD in this population.
The evaluation of a physical health promotion intervention for people with severe mental illness receiving community based accommodational support: a mixed-method pilot study
Authors: Kirschner Viola , Lamp Natalie , Dinc Ümmügülsüm , Becker Thomas , Kilian Reinhold , Mueller-Stierlin Annabel Sandra
Published: January 2022

Background

Unhealthy lifestyle constitutes a cause of increased morbidity and mortality in people with severe mental illness. The aim of this mixed-method pilot study was to investigate the feasibility and preliminary effectiveness of an intervention to promote a health-conscious lifestyle in comparison to care as usual among people with severe mental illness receiving accommodational support in community settings.

Methods

This was a prospective, quasi-experimental, controlled study over four six-month assessment points (t0, + 6 months, + 12 months, + 18 months) with 70 persons with severe mental illness receiving community based accommodational support. Mental health staff members of the housing facilities were trained in Motivational Interviewing and conducted a six-week health course with the intervention group participants in addition to care as usual. Next to the primary outcome - self-rated physical well-being (FEW 16) - anthropometric parameters and unhealthy behaviours (diet, physical activity, alcohol and tobacco consumption, and oral hygiene) were examined. Effectiveness analysis was conducted using mixed-effects regression models with propensity score adjustment to control for selection bias. One year after the end of the intervention, semi-standardized expert interviews were conducted with 12 of these employees and evaluated by content analysis.

Results

The qualitative interviews with mental health staff underline the intervention’s feasibility in people with severe mental illness in sheltered housing, and the acceptability of and satisfaction with the intervention among mental health workers. But in this pilot study no superiority of the HELPS intervention compared to routine care could be demonstrated in terms of the investigated outcomes.

Conclusions

The findings of this pilot study underscore the feasibility and acceptability of health promotion programmes based on Motivational Interviewing and highlight the need to further develop multi-modal programs according to the needs of the target group. Long-term and sustainable support for healthy lifestyles of people with severe mental illness receiving community mental health care requires multi-modal concepts and organisational change.

Prevalence and determinants of wife-beating in Bangladesh: evidence from a nationwide survey
Authors: Hossain Md. Moyazzem , Abdulla Faruq , Rahman Azizur , Khan Hafiz T. A.
Published: January 2022

Background

Intimate partner violence (IPV) is a global public health concern, with women in low- and middle-income countries (LMICs) bearing a disproportionately high burden. This study investigates the prevalence and factors correlated with attitudes regarding wife-beating among Bangladeshi women in urban–rural contexts.

Methods

A sample of 13,033 urban women and 51,344 rural women data from the Bangladesh Multiple Indicator Cluster Survey (MICS) 2019 were analyzed using the Chi-square test and ordinal logistic regression model.

Results

The findings reveal that arguing with her husband is the widespread reason for wife-beating in Bangladesh (urban: 17.3%, rural: 21.9%), followed by neglecting the children (urban: 12.7%, rural: 15.8%). About 8% of urban women and 10% of rural women favoured the opinion that refusing to involve sexual intercourse is a legitimate justification for wife-beating. In comparison, around 5% feel that a husband has a right to beat his wife due to burning food. The respondents’ age, education, marital status, number of children, socioeconomic level, any health or physical difficulty, having problems becoming pregnant, and the husband’s age are all significant factors in justifying wife-beating.

Conclusions

Bangladesh has a massive challenge in eliminating IPV. Women from lower socioeconomic classes, low levels of education, other challenges, and residents of rural areas are particularly more vulnerable than their urban counterparts. Therefore, it is vital to develop a proper action plan that considers women’s education and occupation to raise awareness of the various implications of wife-beating in women, particularly in Bangladesh’s rural areas.

Association of genetic variants of oxidative stress responsive kinase 1 (OXSR1) with asthma exacerbations in non-smoking asthmatics
Authors: Kim Min-Hye , Chang Hun Soo , Lee Jong-Uk , Shim Ji-Su , Park Jong-Sook , Cho Young-Joo , Park Choon-Sik
Published: January 2022

Background

Asthma exacerbation threatens patient's life. Several genetic studies have been conducted to determine the risk factors for asthma exacerbation, but this information is still lacking. We aimed to determine whether genetic variants of Oxidative Stress Responsive Kinase 1 (OXSR1), a gene with functions of salt transport, immune response, and oxidative stress, are associated with exacerbation of asthma.

Methods

Clinical data were obtained from 1454 asthmatics and single nucleotide polymorphisms (SNPs) ofOXSR1were genotyped. Genetic associations with annual exacerbation rate were analyzed depending on smoking status.

Results

Eleven SNPs were selected using Asian data in the International HapMap database. The common allele ofrs1384006C > T ofOXSR1showed a significantly higher annual exacerbation rate than the rare allele in non-smoking asthmatics (CC vs. CT vs. TT: 0.43 ± 0.04 vs. 0.28 ± 0.03 vs. 0.31 ± 0.09,P = 0.004,Pcorr = 0.039). The frequent exacerbators had a significantly higher frequency of the common allele ofrs1384006C > T than did the infrequent exacerbators (74.4% vs. 55.2%,P = 0.004,Pcorr = 0.038).

Conclusion

The common allele ofrs1384006C > T ofOXSR1was associated with the asthma exacerbation rate and a higher risk of being a frequent exacerbator, indicating that non-smoking asthmatics who carry common alleles may be vulnerable to asthma exacerbations.
An 8-ferroptosis-related genes signature from Bronchoalveolar Lavage Fluid for prognosis in patients with idiopathic pulmonary fibrosis
Authors: He Yaowu , Shang Yu , Li Yupeng , Wang Menghan , Yu Dongping , Yang Yi , Ning Shangwei , Chen Hong
Published: January 2022

Background

With the rapid advances of genetic and genomic technologies, the pathophysiological mechanisms of idiopathic pulmonary fibrosis (IPF) were gradually becoming clear, however, the prognosis of IPF was still poor. This study aimed to systematically explore the ferroptosis-related genes model associated with prognosis in IPF patients.

Methods

Datasets were collected from the Gene Expression Omnibus (GEO). The least absolute shrinkage and selection operator (LASSO) Cox regression analysis was applied to create a multi-gene predicted model from patients with IPF in the Freiburg cohort of the GSE70866 dataset. The Siena cohort and the Leuven cohort were used for validation.

Results

Nineteen differentially expressed genes (DEGs) between the patients with IPF and control were associated with poor prognosis based on the univariate Cox regression analysis (all P < 0.05). According to the median value of the risk score derived from an 8-ferroptosis-related genes signature, the three cohorts’ patients were stratified into two risk groups. Prognosis of high-risk group (high risk score) was significantly poorer compared with low-risk group in the three cohorts. According to multivariate Cox regression analyses, the risk score was an independently predictor for poor prognosis in the three cohorts. Receiver operating characteristic (ROC) curve analysis and decision curve analysis (DCA) confirmed the signature's predictive value in the three cohorts. According to functional analysis, inflammation- and immune-related pathways and biological process could participate in the progression of IPF.

Conclusions

These results imply that the 8-ferroptosis-related genes signature in the bronchoalveolar lavage samples might be an effective model to predict the poor prognosis of IPF.
Pulmonary blastoma in a pregnant woman: a case report and brief review of the literature
Authors: Budzik Michał P. , Panek Grzegorz , Bińkowska Małgorzata , Osuch Beata , Borkowska Ewa , Badowska-Kozakiewicz Anna M.
Published: January 2022

Background

Pulmonary blastoma (PB) comprises a rare heterogeneous group of lung tumours typically containing immature epithelial and mesenchymal structures that imitate the embryonic lung tissue and extremely rarely occurs during pregnancy. Although cough and haemoptysis are the most common PB symptoms, they usually indicate other serious pregnancy-related complications.

Case presentation

The article presents the unusual case of a 22-year-old pregnant woman diagnosed with PB during pregnancy.

Conclusions

PB is characterized by poor prognosis and patients’ outcome relies on a rapid diagnosis. Surgery remains the most common and effective treatment. Due to the extreme rarity, the literature contains only single mentions of PB in pregnancy, thus its impact on the course of pregnancy and the developing fetus remains unknown.
Tenebrio molitor: possible source of polystyrene-degrading bacteria
Authors: Machona Oleen , Chidzwondo Farisai , Mangoyi Rumbidzai
Published: January 2022

Background

The excessive use of polystyrene as a packaging material has resulted in a rise in environmental pollution. Polystyrene waste has continually increased water pollution, soil pollution and the closing of landfill sites since it is durable and resistant to biodegradation. Therefore, the challenge in polystyrene disposal has caused researchers to look for urgent innovative and eco-friendly solutions for plastic degradation. The current study focuses on the isolation and identification of bacteria produced by the larvae of beetle Tenebrio molitor (yellow mealworms), that enable them to survive when fed with polystyrene foam as their sole carbon diet.

Materials and methods

The biodegradation of polystyrene by Tenebrio molitor was investigated by breeding and rearing the mealworms in the presence and absence of polystyrene. A comparison was made between those fed with a normal diet and those fed on polystyrene. The mealworms which were fed with polystyrene were then dissected and the guts were collected to isolate and identify the bacteria in their guts. The viability and metabolic activity of the isolates were investigated. The polymerase chain reaction (PCR) followed by sequencing was used for molecular identification of the isolates. The PCR products were directly sequenced using Sanger’s method and the phylogenetic tree and molecular evolutionary analyses were constructed using MEGAX software with the Neighbour Joining algorithm. The evolutionary distances were computed using the Maximum Composite Likelihood method.

Results

The decrease in mass of the polystyrene as feedstock confirmed that the mealworms were depending on polystyrene as their sole carbon diet. The frass egested by mealworms also confirmed the biodegradation of polystyrene as it contained very tiny residues of polystyrene. Three isolates were obtained from the mealworms guts, and all were found to be gram-negative. The sequencing results showed that the isolates were Klebsiella oxytoca ATCC 13182, Klebsiella oxytoca NBRC 102593 and Klebsiella oxytoca JCM 1665.

Conclusion

Klebsiella oxytoca ATCC 13182, Klebsiella oxytoca NBRC 102593 and Klebsiella oxytoca JCM 1665 maybe some of the bacteria responsible for polystyrene biodegradation.

Authors: Yan Shouyi , Yu Jiafan , Zhao Wenxin , Wang Bo , Zhang Liyong
Published: January 2022

Background

Prophylactic central lymph node dissection (PCND) was a basic consensus for patients with papillary thyroid carcinoma (PTC) in China. However, unilateral or bilateral central lymph node dissection (CND) was still controversial. This study aimed at investigating the safety and long-term benefit for the patients undergone with bilateral central lymph node dissection (BCCD).

Methods

581 patients were enrolled and divided randomly into the test and control groups according to range of CND. 285 patients were prospectively assigned to undergo thyroid lobectomy plus BCND in the test group, other 296 patients were assigned to undergo thyroid lobectomy plus ipsilateral central lymph node dissection (ICND) in the control group.

Results

We found that the numbers of total LN and pN1a in the test group were more than that of the control group (p = 0.002,0.004), but there was no difference in the number of metastasized lymph nodes (p = 0.857) and tumor recurrence (p = 0.308). Additionally, in the aspect of postoperative complication (1 day after surgery), the serum levels of parathyroid hormone in the BCND group were lower than that in the ICND group (P = 0.010), and the numbers of transient laryngeal nerve palsy were more than that(p = 0.033). Meanwhile, we further found that pathological tumor size larger than 1 cm and tumor side lymph node metastasis were independent risk factors for contralateral central lymph node metastasis(p = 0.002,0.001).

Conclusion

BCND may be an alternative for patients with tumor sizes larger than 1 cm, but it would significantly increase the rate of transient vocal cord palsy, parathyroid auto transplantation and decreased PTH, but the risk of permanent complications was similar to the ICND group.
Verbalizing spiritual needs in palliative care: a qualitative interview study on verbal and non-verbal communication in two Danish hospices

Published: January 2022

Denmark is considered one of the World’s most secular societies, and spiritual matters are rarely verbalized in public. Patients report that their spiritual needs are not cared for sufficiently. For studying spiritual care and communication, twelve patients admitted to two Danish hospices were interviewed. Verbal and non-verbal communication between patients and healthcare professionals were identified and analysed. Methodically, the Interpretative Phenomenological Analysis was used, and the findings were discussed through the lenses of existential psychology as well as philosophy and theory of caring sciences. Three themes were identified: 1. When death becomes present, 2. Direction of the initiative, and 3. Bodily presence and non-verbal communication. The encounter between patient and healthcare professional is greatly influenced by sensing, decoding, and interpretation. A perceived connection between the patient and the healthcare professional is of great importance as to how the patient experiences the relationship with the healthcare professional.The patient’s perception and the patient’s bodily experience of the healthcare professional are crucial to whether the patient opens up to the healthcare professional about thoughts and needs of a spiritual nature and initiates a conversation hereabout. In this way we found three dynamically connected movements toward spiritual care: 1. From secular to spiritual aspects of care 2. From bodily, sensory to verbal aspects of spiritual care and 3. From biomedical to spiritual communication and care. Thus, the non-verbal dimension becomes a prerequisite for the verbal dimension of spiritual communication to develop and unfold. The behaviour of the healthcare professionals, characterised by the way they move physically and the way they touch the patient, was found to be just as important as verbal conversation when it comes to spiritual care. The healthcare professional can create a connection to the patient through bodily and relational presence. Furthermore, the healthcare professionals should let their sensing and impressions guide them when meeting the patient in dialog about matters of a spiritual nature. Their perception of the patient and non-verbal communication are a prerequisite for being able to meet patient’s spiritual needs with care and verbal communication.

Background

ThoughLippia javanica (Burm.f.) Sprengantioxidant activity has been demonstrated, its effect in protecting the brain from lead (Pb)-induced oxidative damage is unknown. This study investigated the effect ofL. javanicaagainst Pb-induced oxidative stress, inflammation, apoptosis and acetylcholinesterase activity in rat’s brain.

Methods

L. javanicaherbal tea infusion was prepared, its phytochemical constituent was revealed by liquid chromatography-Mass spectrometer (LC-MS) and was administered simultaneously with Pb. Four groups of male Wistar rats (n = 5/group) were used: control received distilled water; Pb-acetate group received 50 mg Pb/ Kg bodyweight (bw), treatment group received 50 mg Pb/ Kg Pb-acetate + 5 ml/kg bwL. javanicaandL. javanicagroup received 5 ml/Kg bw ofL. javanicatea infusion only. After 6 weeks of treatment, oxidative status, acetylcholinesterase activity, inflammation and apoptosis was assessed in brain tissue which was also histologically examined.

Results

Mean brain and heart weight was reduced (p < 0.05) while liver and spleen weights were increased (p < 0.05) in Pb exposed animals but were prevented byL. juvanicatreatment. Treatment withL. javanicaincreased(p < 0.05)overall brain antioxidant status (glutathione and superoxide dismutase activities) and reduced lipid peroxidation (p < 0.05) compared to the Pb exposed animals. Pro-inflammatory cytokine tumour necrotic factor-alpha, pro-apoptosis Bax protein and anticholinesterase activity were reduced (p < 0.05) in Pb-L. javanicatreated animals compared to the Pb exposed group. Histological examination confirmed neuroprotective effects ofL. javanicaas evidenced by reduced apoptosis/necrosis and inflammation-induced vacuolization and oedema in the hippocampus. TheL. javanicatreatment alone had no detrimental effects to the rats. LC-MS analysis revealedL. javanicato be rich in phenolics.

Conclusions

This study demonstrated thatL. javanica,rich in phenolics was effective in reducing Pb-induced brain oxidative stress, inflammation, apoptosis, acetylcholinesterase activity and neuronal damage.

Background

Quercus acutaThunb. (Fagaceae)orJapanese evergreen oak is cultivated as an ornamental plant in South Korea, China, Japan, and Taiwan and used in traditional medicine. The acorn or fruit ofQuercus acutaThunb. (QAF) is the main ingredient of acorn jelly, a traditional food in Korea. Its leaf was recently shown to have potent xanthine oxidase inhibitory and anti-hyperuricemic activities; however, there have been no studies on the biological activity of QAF extracts. Solar ultraviolet light triggers photoaging of the skin, which increases the production of reactive oxygen species (ROS) and expression of matrix metalloproteinase (MMPs), and destroys collagen fibers, consequently inducing wrinkle formation. The aim of this study was to investigate the effect of water extracts of QAF against UVB-induced skin photoaging and to elucidate the underlying molecular mechanisms in human keratinocytes (HaCaT).

Methods

In this study, we used HPLC to identify the major active components of QAF water extracts. Anti-photoaging effects of QAF extracts were evaluated by analyzing ROS procollagen type I in UVB-irradiated HaCaT keratinocytes. Antiradical activity was determined using 2,2-diphenyl-1-picrylhydrazyl and 2,20-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid) assays. The expression of MMP-1 was tested by western blotting and ELISA kits. QAF effects on phosphorylation of the MAPK (p38, JNK, and ERK) pathway and transcription factor AP-1, which enhances the expression of MMPs, were analyzed by western blots.

Results

We identified two major active components in QAF water extracts, gallotannic acid and ellagic acid. The QAF aqueous extracts recovered UVB-induced cell toxicity and reduced oxidative stress by inhibiting intracellular ROS generation in HaCaT cells. QAF rescued UVB-induced collagen degradation by suppressing MMP-1 expression. The anti-photoaging activities of QAF were associated with the inhibition of UVB-induced phosphorylation of extracellular signal-regulated kinase (ERK) and activator protein 1 (AP-1). Our findings indicated that QAF prevents UVB-induced skin damage due to collagen degradation and MMP-1 activation via inactivation of the ERK/AP-1 signaling pathway. Overall, this study strongly suggests that QAF exerts anti-skin-aging effects and is a potential natural biomaterial that inhibits UVB-induced photoaging.

Conclusion

These results show that QAF water extract effectively prevents skin photoaging by enhancing collagen deposition and inhibiting MMP-1 via the ERK/AP-1 signaling pathway.

Published: January 2022

Background

Patrinia scabra Bunge is a well-known herbal medicine for its favorable treatment on inflammatory diseases owing to its effective ingredients, in which iridoid glycoside plays an extremely significant role. This article aimed to improve the content of total iridoid glycosides in crude extract through a series optimization of extraction procedure. Moreover, considering that both pain and inflammation are two correlated responses triggered in response to injury, irritants or pathogen, the article investigated the anti-inflammatory and analgesic activities of P. scabra to screen out the active fraction.

Method

P. scabra was extracted by ultrasonic-microwave synergistic extraction (UMSE) to obtain total iridoid glycosides (PSI), during which a series of conditions were investigated based on single-factor experiments. The extraction process was further optimized by a reliable statistical method of response surface methodology (RSM). The elution fractions of P. scabra extract were prepared by macroporous resin column chromatography. Through the various animal experiment including acetic acid-induced writhing test, formalin induced licking and flinching, carrageenan-induced mice paw oedema test and xylene-induced ear edema in mice, the active fractions with favorable analgesic and anti-inflammatory effect were reasonably screen out.

Results

The content of PSI could reach up to 81.42 ± 0.31 mg/g under the optimum conditions as follows: ethanol concentration of 52%, material-to-liquid ratio of 1:18 g/mL, microwave power at 610 W and extraction time of 45 min. After gradient elution by the macroporous resin, the content of PSI increased significantly. Compared with other concentrations of elution liquid, the content of PSI in 30 and 50% ethanol eluate was increased to reach 497.65 and 506.90 mg/g, respectively. Owing to the pharmacology experiment, it was reasonably revealed that 30 and 50% ethanol elution fractions of P. scabra could relieve pain centrally and peripherally, exhibiting good analgesic and anti-inflammatory activities.

Conclusion

Patrinia scabra possessed rich iridoids and exhibited significant analgesic and anti-inflammatory activities.
