“Be Happy” While You Can: How Expatriates’ Accomplishments Affect Their Subjective Well-Being and Job Satisfaction
Authors: Bastida María , Bande Vilela Belén , Pinto Luisa H. , Castro-Gonzalez Sandra
Published: July 2023

Drawing upon the “happy-productive worker” hypothesis and the Job Demands-Resources model, we examine whether expatriates’ well-being mediates the association between expatriates’ interaction adjustment and job satisfaction; and whether this indirect effect is moderated by expatriates’ perceived accomplishment of the organizational goals for the assignment. Based on responses from 148 assigned expatriates we confirmed the expected indirect influence of expatriates’ well-being and the moderated mediation of expatriates’ accomplishment of organizational goals. This study offers implications for scholars studying subjective well-being in the international work context and organizations aiming to increase their global competitiveness without jeopardizing workers’ well-being.
Minimal clinically important differences in short-term postoperative Knee injury and Osteoarthritis Outcome Score (KOOS) after total knee arthroplasty: A prospective cohort study
Authors: Nishimoto Junji , Tanaka Shigeharu , Inoue Yu , Tanaka Ryo
Published: July 2023

Background/Purpose: The purpose of this study was to determine the short-term minimal clinically important differences (MCIDs) in Knee injury and Osteoarthritis Outcome Score (KOOS) after total knee arthroplasty (TKA) using the anchor method. Methods: Scores for each KOOS subscale were calculated preoperatively and 3 and 6 months postoperatively to create receiver operating characteristic curves, and the MCIDs were calculated. Results: The KOOS MCIDs at 3 months after TKA were 6 for symptoms, 10 for pain, 6 for activities of daily living (ADL), 8 for sport/recreation, and 10 for quality of life (QOL). The KOOS MCIDs at 6 months after TKA were 9 for symptoms, 13 for pain, 10 for ADL, 9 for sport/recreation, and 16 for QOL. The areas under the curves were in the range of 0.8–0.9 at both 3 and 6 months after TKA. Conclusion: MCIDs by KOOS subscales were determined and were highly accurate.
Refractory Jeavons Syndrome from Birth Symptomatic to PLCB1 Mutation
Authors: Spurgeon Alexandria L. , Keaveney Shannon F. , Ng Yu-Tze
Published: July 2023

Jeavons syndrome is a common, often misdiagnosed or overlooked epileptic syndrome presenting with a triad of eyelid myoclonia with or without absence seizures, eye closure-induced EEG paroxysms, and photosensitivity. We present a seven-year-old female who presented with eyelid myoclonia evident since birth with absence seizures and migraines with associated photosensitivity. An EEG with photic stimulation confirmed the diagnosis of Jeavons syndrome. Genetic testing showed a heterozygous mutation in the PLCB1 gene which has been linked to early onset epilepsies and encephalopathic epilepsies. This mutation and her clinical presentation identifies another etiology of Jeavons syndrome and confirms it can begin from birth. Its presence highlights the importance of genetic testing in epileptic patients to better understand the links between genetics and epilepsy syndromes so appropriate treatment can be initiated.

Published: July 2023

Background

Most gay men experience difficulty in coming to terms with their sexual orientation, with their health, wellbeing, and quality of life potentially affected by unpleasant experiences often associated with the formation of their gay identity. It is therefore important for nurses to understand the needs of gay men so that they can accompany them and provide quality care during and after the identity formation process.

Objective

The aim of the study was to explore and describe the identity formation and coming out experiences of gay men.

Methods

A qualitative design with a constructivist naturalist approach was used. Data were collected through in-depth semi-structured interviews with five gay men with experience of the gay identity formation process, and data were analyzed using a thematic analysis method.

Results

The results show that the men needed support, as they reported feeling different and alone during the identity formation and coming out process, and that their mental health was affected. Fear of rejection, negative reactions, and disappointing people were the reasons that led the men not to disclose their sexual orientation to family, while those who had come out defined a feeling of liberation.

Conclusions

The gay identity formation process has potential impacts on health, wellbeing, and quality of life. Nurses need cultural competence training to be able to understand the needs of gay men, accompany them in the identity formation process, and provide individualized and non-heteronormative care. Nurses also need to participate in dismantling a heterosexist social structure.
Chinese cities as digital environmental governance innovators: Evidence from subnational low-Carbon plans
Authors: Hsu Angel , Lili Li , Schletz Marco , Yu Zhitong
Published: July 2023

Research examining the rise of digital environmental governance, particularly at the subnational scale in China, is fairly limited. Critical questions regarding how digital technologies applied at the subnational level may shape or transform environmental governance are only beginning to be explored, given cities’ increasing role as sustainability experimenters and innovators. In this study, we investigate how smart city initiatives that incorporate big data, artificial intelligence, 5G, Internet of Things, and information communication technologies, may play a role in the transformation towards a “digital China.” We conceptualize three major pathways by which digital technology could transform environmental governance in China: through the generation of new data to address existing environmental data gaps; by enhancing the policy analytical capacity of environmental actors through the use of automation, digitalization, and machine learning/artificial intelligence; and last, through reshaping subnational-national, and state-society interactions that may shift balances of power. With its dual prioritization of digital technologies and climate change, China presents an opportunity for examining digitalization trends and to identify gaps in governance and implementation challenges that could present obstacles to realizing the transformative potential of digital environmental management approaches.

Published: July 2023

Multiple myeloma (MM), a malignancy of mature plasma cells, remains incurable. B-cell maturation antigen (BCMA) is the lead protein target for chimeric antigen receptor (CAR) therapy because of its high expression in most MM, with limited expression in other cell types, resulting in favorable on-target, off tumor toxicity. The response rate to autologous BCMA CAR-T therapy is high; however, it is not curative and is associated with risks of cytokine release syndrome (CRS) and immune effector cell–associated neurotoxicity syndrome. Outcomes in patients treated with BCMA CAR-T cells (CAR-Ts) may improve with allogeneic CAR T-cell therapy, which offer higher cell fitness and reduced time to treatment. However, to prevent the risk of graft-versus-host disease (GVHD), allogenic BCMA CAR-Ts require genetic deletion of the T-cell receptor (TCR), which has potential for unexpected functional or phenotype changes. Invariant natural killer T cells (iNKTs) have an invariant TCR that does not cause GVHD and, as a result, can be used in an allogeneic setting without the need for TCR gene editing. We demonstrate significant anti-myeloma activity of BCMA CAR-iNKTs in a xenograft mouse model of myeloma. We found that a long-acting interleukin-7 (IL-7), rhIL-7-hyFc, significantly prolonged survival and reduced tumor burden in BCMA CAR-iNKT–treated mice in both primary and re-challenge settings. Furthermore, in CRS in vitro assays, CAR-iNKTs induced less IL-6 than CAR-Ts, suggesting a reduced likelihood of CAR-iNKT therapy to induce CRS in patients. These data suggest that BCMA CAR-iNKTs are potentially a safer, effective alternative to BCMA CAR-Ts and that BCMA CAR-iNKT efficacy is further potentiated with rhIL-7-hyFc.
Comparative efficacy of different treatments for menstrual migraine: a systematic review and network meta-analysis
Authors: Zhang Han , Qi Jian-Zhi , Zhang Zhi-Hua
Published: July 2023

Background

Menstrual migraine is a subtype of migraine disease that is typically more disabling, longer-lasting, and more challenging to treat. The purpose of this network meta-analysis (NMA) is to compare the relative efficacy of treatments for menstrual migraine.

Methods

We systematically searched databases, including PubMed, EMBASE, and Cochrane, and included all eligible randomized controlled trials in the study. We conducted the statistical analysis using Stata version 14.0, based on the frequentist framework. We used the Cochrane Risk of Bias tool for randomized trials version 2 (RoB2) to assess the risk of bias of the included studies.

Results

This network meta-analysis included 14 randomized controlled trials with 4601 patients. For short-term prophylaxis, frovatriptan 2.5 mg twice daily had the highest probability of effectiveness [OR = 1.87 (95% CI: 1.48 to 2.38)] compared to placebo. For acute treatment, the results showed that sumatriptan 100 mg [OR = 4.32 (95% CI: 2.95 to 6.34)] was the most effective treatment compared to placebo.

Conclusions

These findings suggest that frovatriptan 2.5 mg twice daily was best for short-term prevention, sumatriptan 100 mg were best for acute treatment. More high-quality randomized trials are required to determine the most effective treatment.
Mesoporous silica nanoparticles boost aggressive cancer response to hydrophilic chlorin e6-mediated photodynamic therapy
Authors: Abdel Gaber Sara A. , Stepp Herbert , Abdel Kader Mahmoud H. , Lindén Mika
Published: July 2023

Background

Chlorin e6 trisodium salt (Ce6) is a newly developed hydrophilic photosensitizer designed to mediate anticancer photodynamic therapy (PDT). The response of different cancer types and strategies to boost anticancer efficiency of Ce6-PDT are poorly studied.

Objectives

This study aimed to investigate the response of different cancer types to Ce6-PDT, identify the unresponsive ones, and develop a nanosystem for response enhancement.

Methods

Sk-Br-3, MCF-7, U87, and HF-5 cells were tested in 2D cell cultures. Ce6 uptake, PDT-mediated phototoxicity, ROS production, caspase 3/7 levels, and cell death mode were examined. Furthermore, U87 spheroids were treated with Ce6-PDT. Mesoporous silica nanoparticles (MSN) were synthesized and loaded with Ce6. Cellular uptake and phototoxicity of MSN-Ce6 were compared to free Ce6 in vitro and in vivo.

Results

Ce6 was detectable in the cell cytoplasm within 15 min. U87 cells showed the highest Ce6 cellular uptake. Upon Ce6-PDT, U87 cells were the most responsive ones with an 11-fold increase in ROS production. Here, 5 µM Ce6 and 4 J/cm2 were enough to reach IC50. Ce6-PDT induced both necrotic and caspase-dependent apoptotic cell death and 75% reduction of spheroids volume. Also, MCF-7 and HF-5 cells responded well to Ce6-PDT treatment. Sk-Br-3 breast cancer cells, on the other hand, were the least responsive ones with 80% viability after treatment (5 µM Ce6, 8 J/cm2). However, MSN-Ce6 conjugates increased Sk-Br-3 cellular uptake of Ce6 sevenfold decreasing the IC50 irradiation dose by an order of magnitude. In a very aggressive breast cancer rat model, MSN-Ce6-PDT treatment led to suppression of tumor volume by 50% and elevation of both Bax and caspase 3 by 90% compared to the control while the corresponding values for Ce6-PDT were 30% and 70%, respectively.

Conclusion

The newly developed hydrophilic chlorin and even more its MSN conjugate show high activities in anticancer PDT.
The relationship and interaction between triglyceride glucose index and obesity in the risk of prehypertension population: a cross-sectional study from a survey in Anhui, Eastern China
Authors: Zhang Jiaye , Jia Linlin , Zhu Tongying , Zhu Hao , Shu Li
Published: July 2023

Background

The triglyceride glucose (TyG) index has been regarded as an effective proxy of Insulin resistance (IR). Studies on the TyG index, obesity and the risk of prehypertension (PHT) in elderly people are not apparent currently. The study sought to investigate the predictive value of TyG index and the associations with PHT risk and obesity.

Methods

A community-based cross-sectional study was conducted in Bengbu City, Anhui province, China. Participants older than 65 years accepted questionnaire surveys, physical examinations and blood biochemistry tests. Based on the testing results, indicators including BMI (body mass index), WC (waist circumference), WHtR (waist-to-height-ratio), LAP(Lipid accumulation products) and TyG were calculated. Residents were classified into quartiles by their TyG indexes. Receiver operating characteristic curve (ROC) analysis was carried out to predict obesity indices for PHT. The three additive interaction indicators, RERI (relative excess risk due to interaction), AP (attributable proportion due to interaction) and S (synergy index) were used to assess the interaction impacts.

Results

Two thousand six hundred sixty-six eligible elderly people were included in study and the prevalence of PHT was 71.04% (n = 1894). With increasing TyG index quartile, PHT became more prevalent. After adjusting for confounding factors, the prevalence of PHT risk with TyG levels in the fourth quartile (Q4, male: 2.83, 95%CI: 1.77–4.54; female: 2.75, 95%CI:1.91–3.97) was greater than that in the first quartile (Q1:ref). TyG index (AUC: 0.626, 95%CI: 0.602 to 0.650) was superior than BMI (AUC: 0.609, 95%CI: 0.584 to 0.633) in predicting PHT among females. Eventually, there were significant interactions of TyG index with obesity in males (General obesity: AP = 0.87, 95%CI: 0.72 to 1.02, S = 10.48, 95%CI: 3.43 to 31.97; Abdominal obesity: AP = 0.60,95%CI: 0.38 to 0.83, S = 3.53, 95%CI: 1.99 to 6.26) and females (General obesity: AP = 0.89, 95%CI: 0.79 to 0.98, S = 12.46, 95%CI: 5.61 to 27.69; Abdominal obesity: AP = 0.66, 95%CI: 0.51 to 0.82, S = 3.89, 95%CI:2.54 to 5.98).

Conclusion

TyG index and PHT risk are tightly correlated. The risk of chronic disease in the elderly can be decreased by early detection of PHT utilizing the TyG index. In this research, the TyG index was more predictable than other indicators of obesity.

Published: July 2023

Introduction

Vietnam aims for 95% of commune health stations (CHSs) to have functional hypertension management programs by 2025. However, limited resources may impede the Central Highland region health system from achieving this goal. We assessed the availability and readiness of hypertension management services at CHSs in the Central Highland region and identified challenges to facilitate evidence-based planning.

Methods

We used a mixed-methods cross-sectional design to assess hypertension management services using WHO’s service availability and readiness assessment (SARA) tools in all 579 CHSs in the region, combined with twenty in-depth interviews of hypertension program focal points at communal, district, and provincial levels in all four provinces. We descriptively analyzed quantitative data and thematically analyzed qualitative data.

Results

Hypertension management services were available at 65% of CHSs, and the readiness of the services was 62%. The urban areas had higher availability and readiness indices in most domains (basic amenities, basic equipment, and essential medicines) compared to rural areas, except for staff and training. The qualitative results showed a lack of trained staff and ambiguity in national hypertension treatment guidelines, insufficient essential medicines supply mechanism, and low priority and funding limitations for the hypertension program.

Conclusion

The overall availability and readiness for hypertension diagnosis and management service at CHSs in the Central Highland region were low, reflecting inadequate capacity of the primary healthcare facilities. Some measures to strengthen hypertension programs in the region might include increased financial support, ensuring a sufficient supply of basic medicines, and providing more specific treatment guidelines.
Disseminated nocardiosis in a patient with alcoholic liver cirrhosis: a case report
Authors: Alqurashi Rewaa , Alobida Husam , Albathi Abdullah , Aldraihem Moneera
Published: July 2023

Background

Nocardia are Gram-positive, aerobic, filamentous bacteria that can cause localized or disseminated infections. Immunocompromised patients are at a higher risk of developing Nocardia infection and further dissemination of the disease. To date, limited data have documented the relationship between nocardiosis and alcoholic liver disease.

Case presentation

We report the case of a 47-year-old man with a known history of alcoholic liver cirrhosis. The patient presented to our emergency department with redness, swelling in the left eye, and diminished bilateral vision. Fundus examination of the left eye was obscured, while that of the right eye was consistent with subretinal abscess. Therefore, endogenous endophthalmitis was suspected. Imaging revealed two ring-enhancing lesions in the brain, and multiple bilateral small cystic and cavitary lung lesions. Unfortunately, the left eye eventually eviscerated due to the rapid progression of the disease. Cultures from the left eye were positive for Nocardia farcinica. The patient was started on imipenem, trimethoprim/sulfamethoxazole, and amikacin based on culture sensitivity. The patient’s hospitalization course was complicated by his aggressive and advanced condition, which led to his death.

Conclusions

Although the patient’s condition initially improved with the recommended antibiotic regimens, it led to death owing to the patient’s advanced condition. Early detection of nocardial infection in patients with typical or atypical immunosuppressive conditions may improve overall mortality and morbidity. Liver cirrhosis disrupts cell-mediated immunity and may increase the risk of Nocardia infection.
Discordance of light chain isotypes between serum and glomerular deposits in proliferative glomerulonephritis with monoclonal IgG deposits: a case report and review of the literature
Authors: Miura Shoko , Katayama Kan , Sugimoto Yuka , Tanaka Fumika , Mori Mutsuki , Takahashi Daisuke , Saiki Ryosuke , Hirabayashi Yosuke , Murata Tomohiro , Tawara Isao , Dohi Kaoru
Published: July 2023

Background

Proliferative glomerulonephritis with monoclonal immunoglobulin G (IgG) deposits (PGNMID) is a disease entity with nonorganized granular glomerular deposition with monoclonal proteins of both heavy and light chains. Dysproteinemia was observed in only 30% of the patients with PGNMID. We herein report a case of PGNMID with discrepancy between serum and glomerular deposits.

Case presentation

The patient was a 50-year-old man who had been followed at a local clinic due to hypertension, type 2 diabetes, hyperlipidemia, hyperuricemia, fatty liver, and obesity. Proteinuria had been noted five years previously, and he had been referred to a hematology department due to hyperproteinemia, high gamma globulin, and κ Bence-Jones protein (BJP) positivity one year previously. Bone marrow aspiration showed 5% plasma cells, and he was referred to the nephrology department to evaluate persistent proteinuria. He was hypertensive, and his estimated glomerular filtration rate was 54.2 ml/min/1.73 m2. His urinary protein level was 0.84 g/g⋅Cr. Urine and serum immunofixation showed BJP-κ type and IgG-κ type, respectively. Kidney biopsy showed an increase in mesangial cells and matrix without nodular lesions under a light microscope. Immunofluorescence microscopy showed granular deposits of IgG and C3 on the capillary wall and weak positivity for C1q. IgG3 was predominant among the IgG subclasses, and intraglomerular κ and λ staining was negative for κ and positive for λ. Direct fast scarlet staining was negative. Electron microscopy showed lumpy deposits without a fibrillar structure in the subepithelial area. Based on the above findings, a diagnosis of membranous nephropathy-type PGNMID was made. Since proteinuria increased gradually after three years of treatment with valsartan (40 mg, daily), oral prednisolone (30 mg, daily) was initiated, which led to decreased proteinuria. The dose of oral prednisolone was gradually tapered to 10 mg per day. At that time, proteinuria was 0.88 g/g⋅Cr. We found 204 cases in 81 articles in the PubMed database, among which 8 showed discrepancy in the heavy and/or light chains between serum and kidney.

Conclusions

We experienced a case of membranous nephropathy-type PGNMID with discrepancy in light chains between serum and kidney that was successfully treated with oral prednisolone.
Intra-amniotic and systemic administration of methotrexate with concomitant surgical evacuation of 11 + 5 weeks cervical ectopic pregnancy: a case report
Authors: Ghoubara Ahmed Sameh Moustafa , Elsheikh Juhayna Samier Ahmed , Abdulwahab Hossam Ramadan , Taha Ahmed Abdelrahem Ahmed
Published: July 2023

Background

Cervical pregnancy is a rare type of ectopic pregnancy. The management of cervical pregnancy is challenging because of the rarity of the condition, late presentation, which is associated with increased risk of failed medical treatment, and excessive post-evacuation bleeding that may require hysterectomy. There is no good evidence in the literature regarding the pharmacological management of living cervical ectopic pregnancy of more than 9 + 0 weeks of gestation, and there is no standard protocol on methotrexate doses in these cases.

Case presentation

We present this case to describe a concomitant medical and surgical management of a living 11 + 5 weeks cervical pregnancy. The initial beta-human chorionic gonadotropins (ß-hCG) serum level was 108,730 IU/L. The patient received 60 mg of methotrexate intra-amniotically followed by another dose of 60 mg of methotrexate intramuscularly 24 h later. Fetal heartbeats stopped on day 03. On day 07, the ß-hCG was 37,397 IU/L. On day 13, the patient had evacuation of the remaining products of conception with the insertion of an intracervical Foley catheter to minimize the bleeding. On day 34, the ß-hCG was negative.

Conclusion

The concomitant use of methotrexate to induce fetal demise along with surgical evacuation may be considered in the management of advanced cervical pregnancy to avoid excessive blood loss, and ultimately hysterectomy.
Prolonged usage of fosaprepitant for prevention of delayed chemotherapy-induced nausea and vomiting(CINV) in patients receiving highly emetogenic chemotherapy
Authors: Gao Ai , Guan Shasha , Sun Yinjuan , Wang Lingling , Meng Fanlu , Liu Xia , Gu Liyan , Li Guo , Zhong Diansheng , Zhang Linlin
Published: July 2023

Background

Even though chemotherapy-induced nausea and vomiting (CINV) can be well controlled in the acute phase, the incidence of delayed CINV remains high. In this study, we intend to investigate whether prolonged use of NK-1 receptor antagonist (RA) in addition to 5-HT3 RA and dexamethasone (DEX) was more effective in preventing delayed CINV.

Methods

This randomised, open-label, controlled study was designed to compare the efficacy and safety of fosaprepitant 150 mg given on days 1,3 (prolonged group) versus on day 1 (regular group) in patients receiving highly emetogenic chemotherapy (HEC). All patients also treated with palonosetron on day 1 and DEX on days 1–3. The primary endpoint was the incidence of delayed nausea and vomiting. The second endpoint was AEs. All the above endpoints were defined according to CTCAE 5.0.

Results

Seventy-seven patients were randomly assigned to prolonged group and seventy-nine to regular group. Prolonged group demonstrated superiority in controlling delayed CINV to regular group, with statistically significant lower incidence of nausea (6.17% vs 12.66%, P = 0.0056), and slightly lower incidence of grade 1 vomiting (1.62% vs 3.80%, P = 0.0953) in the delayed phase. In addition, prolonged use of fosaprepitant was safe. No significant difference was found between the two groups regarding constipation, diarrhea, hiccough, fatigue, palpitation and headache in delayed phase.

Conclusions

Prolonged use of fosaprepitant can effectively and safely prevent delayed CINV in patients receiving HEC.

Authors: Smiley Yael , Manget Jaytoya , Barber John , Clarence Iana , Enwerem Nkechi , Jolda Christiana , Quinn Patricia , Wesley Zillah Jackson , White Davene , Chokshi Binny
Published: July 2023

Background

Adolescent parents experience worse health and socioeconomic outcomes compared to older parents. Little is known about the factors that can lead to better health and well-being among teen-headed families. A city-wide collaborative conducted a comprehensive well-being assessment of expectant and parenting teens in Washington, DC.

Methods

An online, anonymous survey was conducted with adolescent parents in Washington, DC, using convenience sampling. The survey consisted of 66 questions adapted from validated scales of quality of life and well-being. Descriptive statistics were used to describe the data overall, by subgroups of mother and father, and by subgroups of parent age. Spearman’s correlations were utilized to demonstrate associations of social supports with well-being metrics.

Results

A total of 107 adolescent and young adult parents from Washington, DC, completed the survey; 80% of respondents identified as mothers and 20% as fathers. Younger adolescent parents rated their physical health better compared to older adolescent and young adult parents. Adolescent parents reported accessing various governmental and community-based resources in the preceding 6 months. The most used resources were supplemental food programs, with 35% receiving Supplemental Nutrition Assistance Program benefits and 24% receiving support from the Special Supplemental Nutrition Program for Women, Infants and Children. There was no significant difference in health-related well-being metrics among those who did and did not receive resources. Having higher self-reported social support was positively correlated with higher self-rated physical health, mental health, and well-being, as well as experiencing positive emotions, and was negatively correlated with experiencing negative emotions.

Conclusion

This snapshot of the well-being of expectant and parenting teens in Washington, DC, showed overall positive physical, mental, and emotional health. Greater social support was correlated with better outcomes in these areas. Future work will leverage the multidisciplinary collaborative to translate these findings into policies and programs that meet the needs of this population.
Shear bond strength of metallic brackets bonded to enamel pretreated with CPP-ACP: a systematic review and meta-analysis of in vitro studies
Authors: Yacout Yomna M. , Nabawy Yomna A. , El-Harouni Nadia M. , Yousry Tarek N.
Published: July 2023

Background

Development of white spot lesions (WSLs) is common among orthodontic patients. Several measures have been introduced to prevent and remineralize the lesions. Casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) is used for both prevention and remineralization. The effect of its application before bonding is controversial. This systematic review was conducted to investigate the most up to date available literature regarding the effect of CPP-ACP enamel pre-treatment on shear bond strength (SBS) of metallic orthodontic brackets.

Methods

A search was conducted in electronic databases (MEDLINE (via PubMed), Scopus, Cochrane Library, Web of Science and Google scholar (grey literature)) up to March 29th, 2023. The inclusion criteria included in vitro studies comparing the SBS of metal orthodontic brackets following pre-treatment of enamel using CPP-ACP versus control. The exclusion criteria included study types other than in vitro studies, studies conducted on non-human enamel, or studies using CPP-ACP in combination with another intervention. The included studies were analysed by two reviewers, independently. The risk of bias assessment was done using a modified risk of bias tool. A Meta-analysis was performed. I2 values and Q-test were used for assessment of heterogeneity. Results were displayed in forest plots with a random-effects model. Standardized mean difference, standard error (SE) and 95% confidence intervals were calculated for all studies.

Results

The search resulted in 76 articles. After duplicate removal and assessment for eligibility, 15 studies were included in the review. High statistical heterogeneity was found among the included studies using I2 values and Q-Test (I2 = 95.147%; Q = 288.456; df = 14; P < 0.001). The overall effect of CPP-ACP pre-treatment on the SBS of metal orthodontic brackets was not significant (Mean difference = 1.163 MPa, SE = 0.757, 95% CI = -0.321, 2.648, p value = 0.125). The use of CPP-ACP for prevention of WSLs did not significantly affect the SBS of brackets (Standardized mean difference = 1.009, SE = 0.884, 95% CI = -0.723, 2.740, p value = 0.254). No significant change was found when CPP-ACP was used for remineralization of WSLs (Standardized mean difference = 1.501, SE = 1.087, 95% CI = -0.630, 3.632, p value = 0.167).

Conclusions

Within the limitations of the study, the evidence suggests that the use of CPP-ACP for either prevention or remineralization of WSLs before bonding does not affect the SBS of metal orthodontic brackets.
Periodontitis in obese adults with and without metabolic syndrome: a cross-sectional study
Authors: Nilsen Astrid , Thorsnes Anette , Lie Stein Atle , Methlie Paal , Bunaes Dagmar F. , Reinholtsen Karen K. , Leknes Knut N.
Published: July 2023

Background

Epidemiological studies support an association between obesity, metabolic syndrome (MetS), and periodontitis. Still, understanding of the effects of low-grade inflammation in obese subjects on periodontitis and influence of MetS remains incomplete. The aims of this cross-sectional study were to explore the association between obesity related variables and periodontitis, and assess if MetS is a risk indicator for periodontitis in a sample of obese adults.

Methods

The study sample comprised 52 adults with a body mass index (BMI) of ≥ 30 kg/m2 referred for obesity therapy at the Obesity Centre at Haukeland University Hospital (HUH), Bergen, Norway. The subjects had prior to enrolment completed a 5-month lifestyle intervention course as part of a 2-year managing program. According to the revised National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III) classification of MetS, 38 subjects were recruited to the MetS group and 14 subjects to the non-MetS group. Medical data including peripheral blood samples were obtained from records at HUH at the time of enrolment. Probing depth, clinical attachment level, tooth mobility, furcation involvement, bleeding on probing (BoP) were recorded and intraoral bitewings evaluated at a full-mouth periodontal examination. Associations between risk variables for obesity/MetS and periodontitis were explored using linear and logistic regression models.

Results

In the present sample 79% of the subjects were diagnosed with periodontitis. The prevalence of stage III/IV periodontitis was 42.9% in the non-MetS group vs. 36.8% in the MetS group (p = 0.200). In the non-MetS group 29.8% of the sites displayed BoP vs. 23.5% in the MetS group (p = 0.048). For stage III/IV periodontitis, the effect of age appeared to be significant for obesity related variables and MetS (p = 0.006, p = 0.002, respectively). None of the other analyses showed significant association with the outcome variables.

Conclusion

In the present sample of obese subjects, periodontitis occurred independently of MetS. Reaching a certain BMI level, suggested association between MetS and periodontitis might be non-significant due to the dominating impact of obesity related variables undermining the effect of other systemic factors.

Trial registration

The principal clinical trial, entitled “Obesity and Oral Diseases”, was prospectively registered in ClinicalTrials.gov with registration NCT04602572 (20.10.2020).
Unilateral ovarian recurrence 5 years after hysterectomy for microinvasive squamous cervical cancer stage IA1: a rare case report
Authors: Tong Longxia , Wu Lin
Published: July 2023

Background

Ovarian metastasis or recurrence of cervical microinvasive squamous cell carcinoma (SCC) is very rare. We report a case of unilateral ovarian recurrence 5 years after hysterectomy for the SCC stage IA1 without lymph vascular space invasion (LVSI).

Case presentation

A 49-year-old female patient suffered from a dull pain in the left lower abdomen for 3 months. And five years ago, she received a laparoscopic hysterectomy for the treatment of stage IA1 (without LVSI) SCC of the cervix. The level of squamous cell carcinoma antigen (SCC-Ag) in serum was significantly elevated (10.60 ng/mL). Pelvic magnetic resonance imaging (MRI) revealed a left ovarian solid tumor measuring 5.5 × 3.9 × 5.6 cm with heterogeneous enhancement. During laparotomy, the left ovarian tumor was measured about 5.0 × 4.5 × 3.0 cm and seemed densely adherent to the posterior peritoneal wall, including the left ureter. The tumor and pelvic lymph node were carefully removed. Postoperative anatomy revealed a solid mass with a greyish-white section. Postoperative pathology showed recurrent moderately differentiated ovarian SCC with negative pelvic lymph nodes. Immunohistochemistry showed that the tumor cells were positive for P16, P63, P40, and CK5/6 markers, and the positive rate of Ki67 was about 80%.

Conclusions

Ovary preservation is reasonable and appropriate in young patients with microinvasive SCC. Ovarian recurrence is rare, but gynecological oncologists should not overlook its possibility. The serum SCC-Ag is an important indicator for monitoring postoperative disease progression.

Background

Surgery is a common treatment strategy for patients with neurofibromatosis type 1 (NF1)-related plexiform neurofibroma (PN) and has limited efficacy. FCN-159 is a novel anti-tumorigenic drug via selective inhibition of MEK1/2. This study assesses the safety and efficacy of FCN-159 in patients with NF1-related PN.

Methods

This is a multicenter, open-label, single-arm, phase I dose-escalation study. Patients with NF1-related PN that was non-resectable or unsuitable for surgery were enrolled; they received FCN-159 monotherapy daily in 28-day cycles.

Results

Nineteen adults were enrolled in the study, 3 in 4 mg, 4 in 6 mg, 8 in 8 mg, and 4 in 12 mg. Among patients included in dose-limiting toxicity (DLT) analysis, DLTs (grade 3 folliculitis) were reported in 1 of 8 patients (16.7%) receiving 8 mg and 3 of 3 (100%) patients receiving 12 mg. The maximum tolerated dose was determined to be 8 mg. FCN-159-related treatment-emergent adverse events (TEAEs) were observed in 19 patients (100%); most of which were grade 1 or 2. Nine (47.4%) patients reported grade 3 study-drug–related TEAEs across all dose levels, including four experiencing paronychia and five experiencing folliculitis. Of the 16 patients analyzed, all (100%) had reduced tumor size and six (37.5%) achieved partial responses; the largest reduction in tumor size was 84.2%. The pharmacokinetic profile was approximately linear between 4 and 12 mg, and the half-life supported once daily dosing.

Conclusions

FCN-159 was well tolerated up to 8 mg daily with manageable adverse events and showed promising anti-tumorigenic activity in patients with NF1-related PN, warranting further investigation in this indication.

Identification of a novel compound heterozygous mutation and a homozygous mutation of SLURP1 in Chinese families with Mal de Meleda
Authors: Wang Tian , Tang Zhuangli , Xiao Tong , Ren Junru , He Shuyao , Liu Yan , Xiao Shengxiang , Wang Xiaopeng
Published: July 2023

Background

Mal de Meleda is an autosomal recessive palmoplantar keratoderma, with SLURP1 identified as the pathogenic gene responsible. Although over 20 mutations in SLURP1 have been reported, only the mutation c.256G > A (p.G87R) has been detected in Chinese patients. Here, we report a novel heterozygous SLURP1 mutation in a Chinese family.

Methods

We assessed the clinical manifestations of two Chinese patients with Mal de Meleda and collected specimens from the patients and other family members for whole-exome and Sanger sequencing. We used algorithms (MutationTaster, SIFT, PolyPhen-2, PROVEAN, PANTHER, FATHMM, mCSM, SDM and DUET) to predict the pathogenetic potential of the mutation detected. We also employed AlphaFold2 and PyMOL for protein structure analysis.

Results

Both patients displayed the typical manifestation of palmoplantar keratoderma. In Proband 1, we detected a novel compound heterozygous mutation (c.243C > A and c.256G > A) in exon 3 of SLURP1. Proband 2 was an adult female born to a consanguineous family and carried a homozygous mutation (c.211C > T). Algorithms indicated both mutations to be probably disease causing. We used AlphaFold2 to predict the protein structure of these mutations and found that they cause instability, as shown by PyMOL.

Conclusions

Our study identified a novel compound heterozygous mutation (c.243C > A and c.256G > A) in a Chinese patient with Mal de Meleda that has the potential to cause instability in protein structure. Moreover, this study expands on the existing knowledge of SLURP1 mutations and contributes to knowledge of Mal de Meleda.

Published: July 2023

Background

Esophageal squamous cell carcinoma (ESCC) is a highly heterogeneous cancer that lacks comprehensive understanding and effective treatment. Although multi-omics study has revealed features and underlying drivers of advanced ESCC, research on molecular characteristics of the early stage ESCC is quite limited.

Materials and methods

We presented characteristics of genomics and transcriptomics in 10 matched pairs of tumor and normal tissues of early ESCC patients in the China region.

Results

We identified the specific patterns of cancer gene mutations and copy number variations. We also found a dramatic change in the transcriptome, with more than 4,000 genes upregulated in cancer. Among them, more than one-third of HOX family genes were specifically and highly expressed in early ESCC samples of China and validated by RT-qPCR. Gene regulation network analysis indicated that alteration of Hox family genes promoted the proliferation and metabolism remodeling of early ESCC.

Conclusions

We characterized the genomic and transcriptomic landscape of 10 paired normal adjacent and early ESCC tissues in the China region, and provided a new perspective to understand the development of ESCC and insight into potential prevention and diagnostic targets for the management of early ESCC in China.
Enrichment strategies to enhance genome editing
Authors: Mikkelsen Nanna S. , Bak Rasmus O.
Published: July 2023

Genome editing technologies hold great promise for numerous applications including the understanding of cellular and disease mechanisms and the development of gene and cellular therapies. Achieving high editing frequencies is critical to these research areas and to achieve the overall goal of being able to manipulate any target with any desired genetic outcome. However, gene editing technologies sometimes suffer from low editing efficiencies due to several challenges. This is often the case for emerging gene editing technologies, which require assistance for translation into broader applications. Enrichment strategies can support this goal by selecting gene edited cells from non-edited cells. In this review, we elucidate the different enrichment strategies, their many applications in non-clinical and clinical settings, and the remaining need for novel strategies to further improve genome research and gene and cellular therapy studies.
EEG-based emergency braking intention detection during simulated driving
Authors: Liang Xinbin , Yu Yang , Liu Yadong , Liu Kaixuan , Liu Yaru , Zhou Zongtan
Published: July 2023

Background

Current research related to electroencephalogram (EEG)-based driver’s emergency braking intention detection focuses on recognizing emergency braking from normal driving, with little attention to differentiating emergency braking from normal braking. Moreover, the classification algorithms used are mainly traditional machine learning methods, and the inputs to the algorithms are manually extracted features.

Methods

To this end, a novel EEG-based driver’s emergency braking intention detection strategy is proposed in this paper. The experiment was conducted on a simulated driving platform with three different scenarios: normal driving, normal braking and emergency braking. We compared and analyzed the EEG feature maps of the two braking modes, and explored the use of traditional methods, Riemannian geometry-based methods, and deep learning-based methods to predict the emergency braking intention, all using the raw EEG signals rather than manually extracted features as input.

Results

We recruited 10 subjects for the experiment and used the area under the receiver operating characteristic curve (AUC) and F1 score as evaluation metrics. The results showed that both the Riemannian geometry-based method and the deep learning-based method outperform the traditional method. At 200 ms before the start of real braking, the AUC and F1 score of the deep learning-based EEGNet algorithm were 0.94 and 0.65 for emergency braking vs. normal driving, and 0.91 and 0.85 for emergency braking vs. normal braking, respectively. The EEG feature maps also showed a significant difference between emergency braking and normal braking. Overall, based on EEG signals, it was feasible to detect emergency braking from normal driving and normal braking.

Conclusions

The study provides a user-centered framework for human–vehicle co-driving. If the driver's intention to brake in an emergency can be accurately identified, the vehicle's automatic braking system can be activated hundreds of milliseconds earlier than the driver's real braking action, potentially avoiding some serious collisions.
Preventive strategies for hypercoagulation in Cushing’s syndrome: when and how
Authors: Lopes Valentim , Marques Olinda , De Sousa Lages Adriana
Published: July 2023

Purpose

The endogenous hypercortisolism that characterizes Cushing’s syndrome (CS) is associated with a state of hypercoagulability that significantly increases the risk of thromboembolic disease, especially, venous events. Despite this certainty, there is no consensus on the best thromboprophylaxis strategy (TPS) for these patients. Our aim was to summarize the published data about different thromboprophylaxis strategies, and to review available clinical tools assisting thromboprophylaxis decision making.

Methods

Narrative review of thromboprophylaxis strategies in patients with Cushing’s syndrome. A search was carried out on PubMed, Scopus and EBSCO until November 14th, 2022, and articles were selected based on their relevance and excluded in case of redundant content.

Results

Literature is scarce regarding thromboprophylaxis strategies to be adopted in the context of endogenous hypercortisolism, most often being a case-by-case decision according to the centre expertise. Only three retrospective studies, with a small number of patients enrolled, evaluated the use of hypocoagulation for the thromboprophylaxis of patients with CS in the post-operative period of transsphenoidal surgery and/or adrenalectomy, but all of them with favourable results. The use of low molecular weight heparin is the most frequent option as TPS in CS context. There are numerous venous thromboembolism risk assessment scores validated for different medical purposes, but just one specifically developed for CS, that must be validated to ensure solid recommendations in this context. The use of preoperative medical therapy is not routinely recommended to decrease the risk of postoperative venous thromboembolic events. The peak of venous thromboembolic events occurs in the first three months post-surgery.

Conclusion

The need to hypocoagulate CS patients, mainly in the post-operative period of a transsphenoidal surgery or an adrenalectomy, is undoubtable, especially in patients with an elevated risk of venous thromboembolic events, but the precise duration and the hypocoagulation regimen to institute is yet to be determined with prospective studies.
Whole genome sequence analysis of CPV-2 isolates from 1998 to 2020
Authors: Sarabandi Sajed , Pourtaghi Hadi
Published: July 2023

Canine parvovirus-2 (CPV-2) is a virus with worldwide spread causing canine gastroenteritis. New strains of this virus have unique characteristics and are resistant to some vaccine strains. Therefore, understanding the root causes of resistance has proven to be of increasing concern to many scientists. This study collected 126 whole genome sequences of CPV-2 subtypes with specific collection dates from the NCBI data bank. The whole genome sequences of CPV-2 collected from different countries were analyzed to detect the new substitutions and update these mutations. The result indicated 12, 7, and 10 mutations in NS1, VP1, and VP2, in that respective order. Moreover, the A5G and Q370R mutations of VP2 are the most common changes in the recent isolates of the CPV-2C subtype, and the new N93K residue of VP2 is speculated to be the cause of vaccine failure. To summarize, the observed mutations, which are increasing over time, causes several changes in viral characteristic. A comprehensive understanding of these mutations can lead us to control potential future epidemics associated with this virus more efficiently.
