Biochemical and proteomic response of the freshwater green alga Pseudochlorella pringsheimii to iron and salinity stressors
Authors: Ismaiel Mostafa M. S. , Piercey-Normore Michele D. , Rampitsch Christof
Published: January 2024

Background

Pseudochlorella pringsheimii (Ppr) is a green unicellular alga rich with chlorophyll, carotenoids, and antioxidants. As a widespread organism, Ppr must face, and adapt to, many environmental stresses and these are becoming more frequent and more extreme under the conditions of climate change. We therefore focused on salinity induced by NaCl and iron (Fe) variation stresses, which are commonly encountered by algae in their natural environment.

Results

The relatively low stress levels improved the biomass, growth rate, and biochemical components of Ppr. In addition, the radical-scavenging activity, reducing power, and chelating activity were stimulated by lower iron concentrations and all NaCl concentrations. We believe that the alga has adapted to the stressors by increasing certain biomolecules such as carotenoids, phenolics, proteins, and carbohydrates. These act as antioxidants and osmoregulators to protect cell membranes and other cellular components from the harmful effects of ions. We have used SDS-PAGE and 2D-PAGE in combination with tandem mass spectrometry to identify responsive proteins in the proteomes of stressed vs. non-stressed Ppr. The results of 2D-PAGE analysis showed a total of 67 differentially expressed proteins, and SDS-PAGE identified 559 peptides corresponding to 77 proteins. Of these, 15, 8, and 17 peptides were uniquely identified only under the control, iron, and salinity treatments, respectively. The peptides were classified into 12 functional categories: energy metabolism (the most notable proteins), carbohydrate metabolism, regulation, photosynthesis, protein synthesis, stress proteins, oxido-reductase proteins, transfer proteins, ribonucleic-associated proteins, hypothetical proteins, and unknown proteins. The number of identified peptides was higher under salinity stress compared to iron stress.

Conclusions

A proposed mechanism for the adaptation of Ppr to stress is discussed based on the collected data. This data could serve as reference material for algal proteomics and the mechanisms involved in mediating stress tolerance.
Esketamine pretreatment during cesarean section reduced the incidence of postpartum depression: a randomized controlled trail
Authors: Xu Shixia , Yang Jiaojiao , Li Jing , Zhang Min , Sun Jie , Liu Qingren , Yang Jianjun
Published: January 2024

Background

Postpartum depression (PPD) is a common mental disease in postpartum women, which has received more and more attention in society. Ketamine has been confirmed for its rapid antidepressant effect in women with PPD. We speculate that esketamine, an enantiomer of ketamine, pretreatment during cesarean can also reduce the incidence of PPD.

Methods

All the parturients enrolled in the study were randomly assigned to two groups: the esktamine group (0.2 mg/kg esketamine) and the control group (a same volume of saline). All the drugs were pumped for 40 min started from the beginning of the surgery. The Amsterdam Anxiety and Information Scale (APAIS) scores before the surgery, the Edinburgh postnatal depression scale (EPDS) scores at 4 d and 42 d after surgery, the Pain Numerical Rating Scale (NRS) scores at 6 h, 12 h, 24 h and 48 h post-operation were evaluated, as well as the adverse reactions were recorded.

Results

A total of 319 parturients were analyzed in the study. The incidence of PPD (EPDS score > 9) in the esketamine group was lower than the control group at 4 days after surgery (13.8% vs 23.1%, P = 0.0430) but not 42 days after surgery (P = 0.0987). Esketamine 0.2 mg/kg could reduce the NRS score at 6 h,12 h and 24 h after surgery, as well as the use of vasoactive drugs during surgery (P < 0.05). The incidences of maternal dizziness (17.0%), blurred vision (5%), illusion (3.8%) and drowsiness (3.8%) in the esketamine group were higher than those of control group (P < 0.05).

Conclusions

Intraoperative injection of esketamine (0.2 mg/kg) prevented the occurrence of depression (EPDS score > 9) at 4 days after delivery but not 42 days. Esketamine reduced the NRS scores at 6 h, 12 h and 24 h after surgery, but the occurrence of maternal side effects such as dizziness, blurred vision, drowsiness and hallucination were increased.

COVID-19 adaptations to a training and support programme to improve primary care response to domestic abuse: a mixed methods rapid study
Authors: Downes Lucy , Barbosa Estela Capelas
Published: January 2024

Background

Increased incidence and/or reporting of domestic abuse (DA) accompanied the COVID-19 pandemic. National lockdowns and enforced social isolation necessitated new ways of supporting victims of DA remotely. Identification and Referral to Improve Safety (IRIS) is a programme to improve the response to domestic abuse in general practice, providing training for general practice teams and support for patients affected by DA, which has previously been proven effective and cost-effective [1–3]. The COVID-19 pandemic required the adaptation of the programme to online training and remote support.

Methods

This study is mixed methods rapid research, which aimed to gather evidence around the relevance, desirability and acceptability of IRIS operating remotely. Quantitative IRIS referral data were triangulated with data from four surveys and 15 interviews. Participants were local IRIS teams, IRIS-trained clinicians, and victim-survivors supported by IRIS services. The study was designed using the Lean Impact approach, allowing quick evaluation of innovation and the impact of social interventions. We carried out a framework analysis of the interviews, which is a qualitative methodology widely used in policy and applied research that enables research teams to move from descriptive accounts to a conceptual explanation of findings [4, 5].

Results

We found that the adaptation to online training and support of IRIS was acceptable and desirable. Most clinicians felt confident addressing DA over the phone and online, although most were more confident face-to-face. While referrals to IRIS services initially declined in March 2020, numbers of referrals increased to pre-pandemic levels by July 2020. Patients felt well supported remotely, although patients who had previously experienced face-to-face support preferred it. Technology was the most frequently mentioned barrier to the change from face-to-face training and support to online training and remote support.

Conclusions

This study contributes to practice by asserting the desirability and acceptability of training clinicians to be able to identify, ask about DA and refer to the IRIS programme during telephone/online consultations. This is of relevance to health and public health commissioners when making commissioning decisions to improve the general practice response to domestic abuse.
What helps patients access web-based services in primary care? Free-text analysis of patient responses to the Di-Facto questionnaire
Authors: Khan Nada , Pitchforth Emma , Winder Rachel , Abel Gary , Clark Christopher E. , Cockcroft Emma , Campbell John
Published: January 2024

Background

The National Health Service (NHS) and general practice are increasingly adopting digital services. These services can impact both positively and negatively upon patient experiences, and access to digital services is not equal amongst all groups. Within a wider project examining digital facilitation (the Di-Facto study) our team conducted a patient survey amongst English primary care practices aiming to investigate patient views of what supports uptake and use of web-based services. This paper reports on the analysis of the free-text responses from the patient survey.

Methods

The Di-Facto patient survey was distributed to practices in eight clinical commissioning groups (CCGs) in England between 2021–2022. We examined free-text responses to two questions relating to access to primary care web-based and support for web-based services. We used qualitative reflexive thematic analysis based on a six-stage process to analyse responses.

Results

Of the 3051 patients who responded to the Di-Facto survey, 2246 provided a free-text response. We present our findings in two major themes: systems and structures and their impact on use of web-based services, and ‘what works for me’, a description of how respondents described what worked, or did not work in terms of their interactions with web-based services. Respondents described how the technology, such as poor practice website design, confusion over multiple digital apps, data security and concerns about eConsultation offerings impacted on use of web-based services. Respondents described practice level barriers, such as a lack of or inconsistent provision, which prevented optimal use of web-based services. Respondents described personal and technical barriers that impacted on their use of digital services, and described which web-based services worked well for them. Respondents felt that web-based services were not a replacement for face-to-face interactions with a doctor.

Conclusions

This analysis of free-text responses from a large patient survey highlights the system, practice, and person level barriers and facilitators to use of digital services in primary care. With an increasing push towards digital solutions in NHS primary care, practices should consider the design, rollout and communication of their web-based services to support patient access.
Aging with my family: a grounded theory approach on the role of family when aging as foreign-born
Authors: Zhou Anna , Hellström Ingrid , Roos Susanne , Ranada Åsa Larsson
Published: January 2024

Background

Research indicates that it is the quality of the closest relationships in the mixture of social relations that matters most for older adults. For older foreign-born, especially those who migrate late in life, the family is often the only socioeconomical resource they can lean on. This study aims to explore how older foreign-born perceive the role of family as they age.

Methods

The study design has a grounded theory approach. Data consist of individual open-ended interviews with 15 foreign-born informants aged between 60 and 85 years old who migrated to Sweden as adults from various parts of the world.

Results

The findings demonstrate that family was an essential part of the informants’ lives as they lived for their families and their families lived for them. Family solidarity was described as a cultural heritage they took over from their original families and a cultural heritage they wished to pass on to their future generations. They found that this was what separated them as foreign-born from native-born. Memories of their parents reminded them of their biological, social, and cultural heritages. The intimate relationship with their spouses in a life course had served as a source of validation of their individual identities and promoted personal growth and self-esteem. The role as a loving and caring parent entailed a sense of accomplishment and satisfaction for the life lived. And now as grandparents, the role as a link between the family’s historical heritage and the future generation entailed not only a sense of coherence as they aged but also hope and meaning beyond their own lives.

Conclusions

The older foreign-born experienced life satisfaction as they aged with their families. Family meant community and solidarity. It was in the family that they found their distinct roles that had defined them. Family was an indispensable part of their social identity. The findings highlight the importance of older foreign-born being studied from a family and lifetime perspective.

Published: January 2024

Background

The Episodic Disability Questionnaire (EDQ) is a generic 35-item patient-reported outcome measure of presence, severity and episodic nature of disability. We assessed the measurement properties of the Episodic Disability Questionnaire (EDQ) with adults living with HIV.

Methods

We conducted a measurement study with adults living with HIV in eight clinical settings in Canada, Ireland, United Kingdom, and United States. We electronically administered the EDQ followed by three reference measures (World Health Organization Disability Assessment Schedule; Patient Health Questionnaire; Social Support Scale) and a demographic questionnaire. We administered the EDQ only 1 week later. We assessed the internal consistency reliability (Cronbach’s alpha; > 0.7 acceptable), and test–retest reliability (Intra Class Correlation Coefficient; > 0.7 acceptable). We estimated required change in EDQ domain scores to be 95% certain that a change was not due to measurement error (Minimum Detectable Change (MDC95%)). We evaluated construct validity by assessing 36 primary hypotheses of relationships between EDQ scores and scores on the reference measures (> 75% hypotheses confirmed indicated validity).

Results

Three hundred fifty nine participants completed the questionnaires at time point 1, of which 321 (89%) completed the EDQ approximately 1 week later. Cronbach’s alpha for internal consistency ranged from 0.84 (social domain) to 0.91 (day domain) for the EDQ severity scale, and 0.72 (uncertainty domain) to 0.88 (day domain) for the EDQ presence scale, and 0.87 (physical, cognitive, mental-emotional domains) to 0.89 (uncertainty domain) for the EDQ episodic scale. ICCs for test–retest reliability ranged from 0.79 (physical domain) to 0.88 (day domain) for the EDQ severity scale and from 0.71 (uncertainty domain) to 0.85 (day domain) for the EDQ presence scale. Highest precision was demonstrated in the severity scale for each domain (MDC95% range: 19–25 out of 100), followed by the presence (MDC95% range: 37–54) and episodic scales (MDC95% range:44–76). Twenty-nine of 36 (81%) construct validity hypotheses were confirmed.

Conclusions

The EDQ possesses internal consistency reliability, construct validity, and test–retest reliability, with limited precision when administered electronically with adults living with HIV across in clinical settings in four countries. Given the measurement properties, the EDQ can be used for group level comparisons for research and program evaluation in adults living with HIV.
Effect of psychosocial interventions for depression in adults with chronic kidney disease: a systematic review and meta-analysis
Authors: Yang Hui , Qi Li , Pei Dongmei
Published: January 2024

Background

People with chronic kidney disease (CKD) treated with dialysis are frequently affected by depression. Psychotherapy has been reported to decrease depressive symptoms in various chronic diseases and is a potential treatment option for depression. We aimed to perform a systematic review and meta-analysis to evaluate the effect of psychotherapy on depression in adults with CKD.

Methods

We searched MEDLINE, Embase, Web of Science, and Cochrane for published studies up to October 31, 2023. Two investigators independently reviewed the included studies and extracted relevant data. Randomized controlled trials (RCTs) assessing the impact of interventions that provide psychological, emotional, or social support without the use of pharmacological substances on depressive symptoms in people with CKD were included and summarized. Scores on different tools for depressive assessment and quality of life were pooled.

Results

A total of 19 RCTs published between 2004 and 2023 were included and analyzed. The weighted mean difference (WMD) for all included studies with regard to depression was − 2.32 (95%CI=-3.83, -0.80, P = 0.003). The WMD for Beck Depression Inventory (BDI) score of depression was − 3.27 (95%CI=-7.81, 1.27, P = 0.158) with significant heterogeneity (I2 = 95.1%). Significant WMD was detected for the Hospital Anxiety and Depression Scale (HADS) tool: WMD=-1.90, 95%CI=-2.91, -0.90, P < 0.001. The WMD for all included studies regarding quality of life was 1.21 (95%CI=-0.51, 2.93, P = 0.168). The WMD for Kidney Disease Quality of Life Short Form (KDQOL-SF) score was 4.55 (95%CI = 0.50, 8.60, P = 0.028). The WMD for SF-36 score was 0.02 (95%CI=-10.33, 10.36, P = 0.998). Significant difference on outcomes of S-PRT scale was observed (WMD = 2.42, 95%CI = 1.07, 3.76, P < 0.001).

Conclusions

Psychosocial interventions probably reduce the depression level among CKD patients. Preliminary evidence suggests that psychosocial interventions might be beneficial for the quality of life in CKD patients. Our results provide medical facilities with an evidence-based basis for establishing psychosocial interventions in kidney care settings.
Novel cuproptosis-related prognostic gene profiles in preeclampsia
Authors: Tang Xiaotong , Liu Yi , Zhang Yuanyuan
Published: January 2024

Background

Preeclampsia (PE) is a pregnancy-specific disorder with complex pathogenesis. Cuproptosis is a novel identified form of programmed cell death, however, the link between cuproptosis and clinical outcomes in PE is still not fully understood. In this study, we searched for cuproptosis-related genes (CRGs) in the placental tissues of normal and PE patients to clarify the importance of cuproptosis in the development of PE and provide potential predictive indicators for the occurrence of PE.

Methods

Using RNA sequencing data in the GEO database, we conducted functional enrichment analysis of Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG) and Gene Set Enrichment Analysis (GSEA), supported by linear regression model and operating characteristic curve (ROC) curve analysis, and summarized the role of CRGs in preeclampsia.

Results

A total of 2831 differentially expressed genes related to PE were screened through multiple database analyses. After further intersection with 19 reported CRGs, 5 CRGs have been closely associated with the pathogenesis of PE, including NFE2L2, PDHA1, PDHB, DLD and GLS. NFE2L2 was identified as a key central gene. Pearson correlation analysis showed that CRGs could be related to several maternal and fetal outcome factors, including the highest pregnancy blood pressure, placenta weight, umbilical blood flow pulsatility index (PI), and neonatal weight. Linear regression equation revealed that the expression of NFE2L2 is negatively correlated with the highest pregnancy blood pressure and umbilical blood flow PI but positively correlated with placental weight and neonatal weight. QRT-PCR showed that the expression of these CRGs was significantly lower in placental tissues.

Conclusions

This cuproptosis pattern may be a potential prognostic factor in patients with PE and could provide new insights into disease progression.
FERMT1 promotes cell migration and invasion in non-small cell lung cancer via regulating PKP3-mediated activation of p38 MAPK signaling
Authors: Liu Bao , Feng Yan , Xie Naiying , Yang Yang , Yang Dameng
Published: January 2024

Background

Fermitin family member 1 (FERMT1) is highly expressed in many tumors and acts as an oncogene. Nonetheless, the precise function of FERMT1 in non-small cell lung cancer (NSCLC) has not been clearly elucidated.

Methods

Bioinformatics software predicted the FERMT1 expression in NSCLC. Transwell assays facilitated the detection of NSCLC cell migration and invasion. Western blotting techniques were employed to detect the protein levels regulated by FERMT1.

Results

FERMT1 exhibited high expression levels in NSCLC and was linked to the patients’ poor prognosis, as determined by a variety of bioinformatics predictions combined with experimental verification. FERMT1 promoted the migration and invasion of NSCLC and regulated epithelial to mesenchymal transition (EMT) -related markers. Further studies showed that FERMT1 could up-regulate the expression level of plakophilin 3(PKP3). Further research has indicated that FERMT1 can promote cell migration and invasion via up-regulating PKP3 expression. By exploring downstream signaling pathways, we found that FERMT1 has the capability to activate the p38 mitogen-activated protein kinases (p38 MAPK) signaling pathway, and knocking down PKP3 can counteract the activation induced by FERMT1 overexpression.

Conclusions

FERMT1 was highly expressed in NSCLC and can activate the p38 MAPK signaling pathway through up-regulation of PKP3, thus promoting the invasion and migration of NSCLC.
Short-term outcomes and long-term quality of life of reconstruction methods after proximal gastrectomy: a systematic review and meta-analysis
Authors: Li Bailong , Wang Yinkui , Li Baocong , Shan Fei , Li Ziyu
Published: January 2024

Background

The optimal reconstruction method after proximal gastrectomy remains unclear. This systematic review and meta-analysis aimed to compare the short-term outcomes and long-term quality of life of various reconstruction methods.

Methods

PubMed, Embase, Web of Science and Cochrane Library were searched to identify comparative studies concerning the reconstruction methods after proximal gastrectomy. The reconstruction methods were classified into six groups: double tract reconstruction (DTR), esophagogastrostomy (EG), gastric tube reconstruction (GT), jejunal interposition (JI), jejunal pouch interposition (JPI) and double flap technique (DFT). Esophagogastric anastomosis group (EG group) included EG, GT and DFT, while esophagojejunal anastomosis group (EJ group) included DTR, JI and JPI.

Results

A total of 27 studies with 2410 patients were included in this meta-analysis. The pooled results indicated that the incidences of reflux esophagitis of DTR, EG, GT, JI, JPI and DFT were 7.6%, 27.3%, 4.5%, 7.1%, 14.0%, and 9.1%, respectively. The EG group had more reflux esophagitis (OR = 3.68, 95%CI 2.44–5.57, P < 0.00001) and anastomotic stricture (OR = 1.58, 95%CI 1.02–2.45, P = 0.04) than the EJ group. But the EG group showed shorter operation time (MD=-56.34, 95%CI -76.75- -35.94, P < 0.00001), lesser intraoperative blood loss (MD=-126.52, 95%CI -187.91- -65.12, P < 0.0001) and shorter postoperative hospital stay (MD=-2.07, 95%CI -3.66- -0.48, P = 0.01). Meanwhile, the EG group had fewer postoperative complications (OR = 0.68, 95%CI 0.51–0.90, P = 0.006) and lesser weight loss (MD=-1.25, 95%CI -2.11- -0.39, P = 0.004). For specific reconstruction methods, there were lesser reflux esophagitis (OR = 0.10, 95%CI 0.06–0.18, P < 0.00001) and anastomotic stricture (OR = 0.14, 95%CI 0.06–0.33, P < 0.00001) in DTR than the esophagogastrostomy. DTR and esophagogastrostomy showed no significant difference in anastomotic leakage (OR = 1.01, 95%CI 0.34–3.01, P = 0.98).

Conclusion

Esophagojejunal anastomosis after proximal gastrectomy can reduce the incidences of reflux esophagitis and anastomotic stricture, while esophagogastric anastomosis has advantages in technical simplicity and long-term weight status. Double tract reconstruction is a safe technique with excellent anti-reflux effectiveness and favorable quality of life.

Pulsatilla saponin D regulates ras-related C3 botulinum toxin substrate 3 (RAC3) to overcome resistance to paclitaxel in lung adenocarcinoma cells
Authors: Lu Yanyan , He Wubin , Huang Xiaoxu , Xiao Xuyang
Published: January 2024

Background

Paclitaxel, a tubulin-binding agent, is a Food and Drug Administration-approved first-line drug for the treatment of non-small cell lung cancer (NSCLC), for both squamous and non-squamous cell lung carcinoma, with paclitaxel/carboplatin + bevacizumab a common chemotherapy regimen for stage IV non-squamous NSCLC; however, primary or acquired resistance to paclitaxel is gradually increasing, leading to treatment failure.

Methods

Our results show that Ras-related C3 botulinum toxin substrate 3 (RAC3) is overexpressed in cultured paclitaxel-resistant cells and that RAC3 expression levels are negatively correlated with sensitivity of lung adenocarcinoma cells to paclitaxel. Pulsatilla saponin D could inhibit RAC3 expression, and we hypothesize that it may block paclitaxel resistance. Further, we found that treatment with paclitaxel combined with Pulsatilla saponin D, can overcome lung adenocarcinoma cell resistance to paclitaxel alone in cell culture and mouse xenograft models.
Resident operative time as an independent predictor of early post-operative cataract surgery outcomes and supervising attending surgeon impact: a retrospective case series
Authors: Andrews Hans W , Lin George T , Lindsey Jennifer L , Ji Xiangyu , Chen Qingxia , Chomsky Amy S
Published: January 2024

Background

The authors sought to determine if resident operative time in cataract extraction and intraocular lens insertion (CE/IOL) affects early visual outcomes and post-operative recovery. They further sought to investigate if attending surgeons can reduce resident operative time.

Methods

This retrospective, chart-review, case series at single Veterans Affairs Hospital (VA Tennessee Valley Healthcare System) studied resident cataract surgeries between March 1, 2018 and March 31, 2020. Following power analysis, 420 eyes of 400 patients from all resident cataract surgeries were included. Eyes with attending as primary surgeon, laser-assisted cataract surgery, or concurrent secondary procedures were excluded. Linear mixed effect models were used to study the association between operative time and visual outcomes while adjusting for covariates including cumulative dissipated energy, preoperative factors, and intraoperative complications.

Results

Longer operative time was statistically associated with worse post-operative-day 1 (POD1) pinhole visual acuity (PH-VA) adjusting for cumulative dissipated energy and other operative factors (p = 0.049). Although resident physicians were the primary surgeons, the operative times were different between the ten supervising attending surgeons in the study (p < 0.001).

Conclusion

The results suggest that increased resident operative time is a significant, independent risk factor for decreased POD1 PH-VA. Increased resident operative time is not associated with worsened long term visual outcomes. Attending surgeons may be able to reduce resident operative time, which is associated with improved early visual outcomes.
Family based behavioral treatment in adolescents suffering from obesity: evolution through adulthood
Authors: Chamay Weber Catherine , Gal-Duding Claudine , Maggio Albane BR
Published: January 2024

Background

Family Based Behavioral Treatments (FBBT) are reported to have a favorable impact on the short and mid-term evolution on the body mass index (BMI) of adolescents suffering from obesity. This study investigated the long-term BMI z-score evolution, as well as variables associated with favorable or unfavorable evolution in adolescents who beneficiated from FBBT group therapy treatment for obesity.

Methods

This was a prospective study including adolescents who participated in FBBT group therapy for obesity sessions (n = 131). All adolescents were invited for a study’s clinical interview 4 years after the therapy, during which their weight and height were measured, and they answered a questionnaire on some life habits. Anthropometric measurements at the time of therapy as well as socio-demographic data were retrospectively extracted from the electronic medical record.

Results

Seventy-six subjects (57% of the sample) accepted to participate in the study. At the study’s clinical interview (mean 5.5 years after FBBT), 52.6% of the adolescents showed a favorable evolution of their weight status defined as a decrease (>-0.2) or stabilization (between − 0.2 and + 0.2) of their BMI z-score. 32% were engaged in a daily physical activity and 40.6% monitored their weight at least once a week or more. Only these 2 variables were associated with a favorable evolution (p = 0.009 and p = 0.001, respectively). Less than half of the sample (45.9%) have maintained a medical weight-management follow up, of which 67% had a BMI equal or more than 30.

Conclusions

Long-term evolution of the BMI z-score was favorable for most of the adolescents, emphasizing the potential benefits of FBBT treatment on the long term for adolescents suffering from obesity. This study highlighted the difficulty for long-term weight management follow up in this population at risk of numerous medical comorbidities, confirming the need to improve adherence to weight management treatment at this age of transition of care. Prospective observational study registered.
Aesthetic chills mitigate maladaptive cognition in depression
Authors: Schoeller Felix , Jain Abhinandan , Adrien Vladimir , Maes Pattie , Reggente Nicco
Published: January 2024

Background

Depression is a major global health challenge, affecting over 300 million people worldwide. Current pharmacological and psychotherapeutic interventions have limited efficacy, underscoring the need for novel approaches. Emerging evidence suggests that peak emotional experiences characterized by awe, transcendence, and meaning hold promise for rapidly shifting maladaptive cognitive patterns in depression. Aesthetic chills, a peak positive emotion characterized by physical sensations such as shivers and goosebumps, may influence reward-related neural pathways and hold promise for modifying core maladaptive beliefs rooted in early adverse experiences.

Methods

We enrolled 96 patients diagnosed with major depressive disorder. A validated database of multimedia known to elicit chills responses (ChillsDB) was used for stimulus presentation. Participants’ emotional responses were assessed using the Emotional Breakthrough Inventory (EBI), while shifts in self-schema were measured via the Young Positive Schema Questionnaire (YSPQ).

Results

The study found that chill-inducing stimuli have the potential to positively influence the core schema of individuals with depression, impacting areas of self-related beliefs. The associated phenomenology triggered by chills appears to share similarities with the altered states of consciousness induced by psychedelic substances like psilocybin.

Conclusions

These preliminary results suggest that the biological processes involved in aesthetic chills could be harnessed as a non-pharmacological intervention for depression. However, further investigation is necessary to comprehensively understand the neurophysiological responses to chills and to evaluate the practicality, effectiveness, and safety of utilizing aesthetic chills as a preventive measure in mental health care.
Adolescents’ electronic devices use during the COVID-19 pandemic and its relationship to anxiety and depression levels: a cross-sectional study
Authors: Hamshari Suha , Yaseen Shaban , Zayed Mosab , Dalasha Asala , Maraqa Beesan , Nazzal Zaher
Published: January 2024

Background

The aim of this study is to assess the prevalence of anxiety and depression symptoms among adolescent students in the West Bank region of Palestine, with a particular focus on the impact of electronic device usage on their mental well-being.

Methods

This cross-sectional study included a representative sample of 1,140 adolescents enrolled in governmental secondary schools. We targeted schools located in Nablus, Ramallah, and Hebron districts, which, respectively, represent the northern, central, and southern regions of the West Bank. We collected data on their sociodemographic characteristics, patterns of electronic device usage, scores from the Beck Depression Inventory-II, and the 7-item Generalized Anxiety Disorder scale, all gathered through a self-administered online questionnaire. To explore the independent relationship between anxiety, depression, and various factors, we calculated odds ratios and their corresponding 95% CI using a binary logistic regression model.

Results

The study revealed a prevalence of moderate to severe anxiety at 35.4% [95% CI: 32.7–38.3%] and moderate to severe depression at 23.9% [95% CI: 21.4–26.4%]. Notably, anxiety scores were significantly higher among females [OR = 3.8, 95% CI: 2.5–5.9], individuals with lower academic performance [OR = 3.4, 95% CI: 2.1–5.4], and smokers [OR = 1.9, 95% CI: 1.1-3.0]. Similarly, significantly elevated depressive scores were observed among females [OR = 2.0, 95% CI: 1.3–3.1], those with lower academic performance [OR = 3.4, 95% CI: 2.1–5.4], and smokers [OR = 1.9, 95% CI: 1.3–2.8]. Conversely, students who used electronic devices for shorter durations were less likely to experience depression [OR = 0.49, 95% CI: 0.32–0.76] or anxiety [OR = 0.47, 95% CI: 0.32–0.69].

Conclusion

Considering the alarming rates of anxiety and depression in adolescents, along with their connection to the time spent using electronic devices, we strongly recommend the creation of initiatives and support networks to alleviate this issue’s impact. Encouraging healthier lifestyles, such as reducing screen time and increasing physical activity, could potentially enhance the mental well-being of adolescents.

Background

Despite the advancements in knowledge about health care for older adults, essential gaps persist regarding the effects of chronic diseases as epidemiological markers of the state of functional dependence. This study aimed to identify the prevalence of moderate and severe functional dependence in Brazilian older adults and its association with chronic diseases and verify the multimorbidity patterns by dependence status.

Methods

This cross-sectional analytical study used data from 11,177 community-dwelling Brazilian older adults from the 2013 National Health Survey conducted in Brazil. The dependent variables were moderate and severe functional dependence in basic activities of daily living (BADLs) and instrumental ADLs (IADLs). The independent variables were defined based on the questions applied to measure each morbidity in a self-reported manner and asked, "Has a doctor ever diagnosed you as having (each disease)? Multimorbidity was simultaneously considered present for older adults with ≥ 2 chronic morbidities. The association between functional dependence on BADLs and IADLs separately by severity and the independent variables was verified from crude and adjusted estimates of the point prevalence ratios and their 95% confidence intervals using the regression model Poisson with robust variance. To group diseases into patterns, exploratory factor analysis was used.

Results

The prevalences of moderate and severe BADL dependence were 10.2% (95% CI, 9.6–10.7) and 4.8% (95% CI, 4.4–5.2), respectively. Moderate and severe IADL dependence prevalences were 13.8% (95% CI, 13.1–14.4) and 15.6% (95% CI, 14.9%–16.2), respectively. When changing the condition from moderate to severe dependence in BADLs, in the presence of other mental illnesses and stroke, the probability of dependence increased more than four times in the case of other mental illnesses and more than five times for stroke. There was a linear trend for dependence severity, both moderate and severe, whereas, for severe dependence on IADLs, this same factor maintained a linear trend toward an increase in probability as the number of diseases simultaneously increased.

Conclusions

Chronic diseases are associated with functional dependence, with greater emphasis on mental illnesses and stroke in severe disability, considering their acute adverse effects.

Published: January 2024

Background

Low back pain is the leading cause of productivity loss, imposes a significant economic burden on the patients and society. Oxidative stress is considered a critical factor in the complex pathophysiological process and pathogenic mechanism of low back pain. Adjustment dietary pattern can effectively increase antioxidant biomarkers levels within the body to reduce oxidative stress. The composite dietary antioxidant index (CDAI) serves a reliable scoring system for quantifying the potential dietary antioxidant capacity of daily diets.

Objective

We aim to investigate the potential association between CDAI and low back pain, in order to enhance the management of low back pain through dietary guidance.

Methods

This study included 17,682 participants from the National Health and Nutrition Examination Survey (NHANES) 1999–2000, 2001–2002, 2003–2004 and 2009–2010. The weighted logistic regression model was used to investigate the association between CDAI and low back pain, while restricted cubic spline (RCS) was employed to examine non-linear trend and cutoffs.

Results

After adjusting for all confounders, the results showed that there was no significant association between CDAI and low back pain. However, individuals in the highest quartile of CDAI exhibited an 11.7% less likelihood of experiencing a low back pain than those in the lowest quartile (OR = 0.883; 95% CI [0.787,0.991], P = 0.034), and the trend test was also significant (P for trend < 0.001). RCS indicated a linear relationship between CDAI and low back pain (P for non-linear = 0.876). Gender subgroup analysis showed that this negative association was significant in the female population (OR = 0.983; 95% CI [0.968, 0.998], P = 0.027), and females in the highest quartile of CDAI were 19.7% less likely to suffer low back pain than those in the lowest quartile (OR = 0.803; 95% CI [0.682,0.945], P = 0.008). Additionally, the changes in zinc (OR = 1.009; 95% CI [1.002, 1.016], P = 0.015) and selenium (OR = 0.379; 95% CI [0.164, 0.875], P = 0.023) per milligram were independently associated with low back pain.

Conclusion

The fully adjusted model showed no significant association between CDAI and low back pain, but it was significant in quartiles. Meanwhile, subgroup analysis by gender revealed a negative association between CDAI and low back pain in the female population. Additionally, the findings of this study also suggested that the antioxidant diets should be studied in a dietary pattern context.

Authors: Cho Seong-Sik , Jang Tae-Won , Kang Mo-Yeol
Published: January 2024

Background

This study investigates the relationship between ergonomic risk exposures and insomnia symptoms, using data representative of Korea’s general working population.

Methods

Data from the 5th Korean Working Conditions Survey were used for this study. The eligible population (employees) for the current study was 37,026. Insomnia symptoms were estimated using the minimal insomnia symptom scale (MISS) questionnaire. Logistic regression analysis was conducted to explore the association between ergonomic risks and insomnia symptoms.

Results

All the investigated ergonomic risks increased odd ratios (ORs) for insomnia symptoms: Tiring or painful positions (OR, 1.64; 95% CI, 1.43–1.88); lifting or moving heavy loads (OR, 2.33; 95% CI, 1.99–2.71); long periods of standing (OR, 1.47; 95% CI, 1.29–1.69); and repetitive hand or arm movements (OR, 1.46; 95% CI, 1.29–1.67). The mediated proportion of musculoskeletal pain was 7.4% (95% CI, 5.81–10.13), and the mediated proportion of feeling of exhaustion was 17.5% (95% CI, 5.81–10.13).

Conclusions

This study provides evidence for the relationship between ergonomic risks and insomnia symptoms, for which musculoskeletal pains and the feeling of exhaustion may be potential mediators.

Authors: Hu Dahai , Wang Nan , Wang Huajun , Fan Dongyi , Teng Qiang , Zheng Xiaofei , Hou Huige
Published: January 2024

Background

To compare the clinical efficacies of arthroscopic anterior talofibular ligament suture augmentation repair and modified suture augmentation repair in patients with chronic ankle instability (CAI).

Methods

From October 2019 to August 2020, 100 patients with CAI were enrolled after propensity score matching analysis and observed for two years. Among them, 50 underwent modified suture augmentation repair and the other 50 underwent suture augmentation repair. The clinical efficacies of CAI treatments were evaluated using the American Orthopedic Foot and Ankle Society (AOFAS) clinical rating scale, visual analog scale (VAS), and anterior drawer test scores.

Results

The postoperative AOFAS score of the modified suture augmentation repair group (83.8 ± 11.3) was significantly higher than that of the suture augmentation repair group (76.3 ± 11.3; P = 0.001). The VAS (P = 0.863) and anterior drawer test (P = 0.617) scores were not significantly different between the two treatment groups.

Conclusion

Both the modified suture augmentation repair and suture augmentation repair demonstrated good clinical efficacies. The AOFAS score of the modified suture augmentation repair group was superior to that of the conventional suture augmentation repair group. Thus, modified suture augmentation repair is a feasible and practical surgical technique for CAI treatment.

Published: January 2024

Study design

A retrospective study.

Purpose

The study objectives were as follows: 1) to analyze the factors influencing the occurrence of the intravertebral shell phenomenon (ISP) after thoracolumbar spinal fracture surgery and the evolutionary outcome of this phenomenon; and 2) to make recommendations for the clinical prevention and treatment of ISP.

Methods

We retrospectively analyzed 331 patients with single-segment fractures of the thoracolumbar spine treated with internal fixation via a pedicle screw-rod system. Univariate and multivariate logistic regression were used to analyze factors influencing ISP.

Results

A total of 260 patients (78.5%) developed ISP after surgery. Reduced bone mineral density, screw insertion depth, degree of vertebral body injury, and excessive vertebral body spreading were significantly associated with the occurrence of ISP (P < 0.05). A total of 166 of the 260 patients were reviewed via CT at 1 year postoperatively. Among them, 104 patients (62.6%) showed shrinkage or healed vertebral cavities, and 62 patients (37.4%) showed enlarged vertebral cavities or collapsed endplates.

Conclusion

In clinical management, surgeons need to focus on risk factors for ISP, which include decreased bone density, preoperative vertebral overcompression, intraoperative vertebral overextension, screw insertion depth, and the degree of vertebral repositioning. At the 1-year postoperative follow-up, some of the vertebrae with ISP failed to heal or even showed vertebral cleft enlargement, which would affect the stability of the internal fracture fixation device and the quality of the patient's daily life.

Published: January 2024

Objectives

To evaluate the histological parameters and bone mechanical properties around implants with low primary stability (PS) in grafted bone substitutes within an oversized osteotomy.

Materials and methods

An oversized osteotomy penetrating the double cortical bone layers was made on both femora of 24 New Zealand white rabbits. Bilaterally in the femur of all animals, 48 implants were installed, subdivided into four groups, corresponding to four prepared tissue-engineering bone complexes (TEBCs), which were placed between the implant surface and native bone wall: A: tricalcium phosphate β (TCP-β); B: autologous adipose derived-stem cells with TCP-β (ASCs/TCP-β); C: ASCs transfected with the enhanced-GFP gene with TCP-β (EGFP-ASCs/TCP-β); D: ASCs transfected with the BMP-2 gene with TCP-β (BMP2-ASCs/TCP-β). Trichrome fluorescent labeling was conducted. Animals were sacrificed after eight weeks. The trichromatic fluorescent labeling (%TFL), area of new bone (%NB), residual material (%RM), bone-implant contact (%BIC), and the removal torque force (RTF, N/cm) were assessed.

Results

ASCs were successfully isolated from adipose tissue, and the primary ASCs were induced into osteogenic, chondrogenic, and adipogenic differentiation. The BMP-2 overexpression of ASCs sustained for ten days and greatly enhanced the expression of osteopontin (OPN). At eight weeks post-implantation, increased %NB and RTF were found in all groups. The most significant value of %TFL, %BIC and lowest %RM was detected in group D.

Conclusion

The low PS implants osseointegrate with considerable new bone in grafted TEBCs within an oversized osteotomy. Applying BMP-2 overexpressing ASCs-based TEBC promoted earlier osseointegration and more solid bone mechanical properties on low PS implants. Bone graft offers a wedging effect for the implant with low PS at placement and promotes osteogenesis on their surface in the healing period.
