Immunotherapy vs Best Supportive Care for Patients With Hepatocellular Cancer With Child-Pugh B Dysfunction.

Whether patients with Child-Pugh class B (CP-B) cancer with unresectable hepatocellular carcinoma (uHCC) benefit from active anticancer treatment vs best supportive care (BSC) is debated. To evaluate the association of immune checkpoint inhibitor (ICI)-based therapies vs BSC with overall survival (OS) of patients with uHCC and CP-B liver dysfunction. This retrospective, multicenter, international clinical case series examined data of patients with CP-B with uHCC who were receiving first-line ICI-based regimens from September 2017 to December 2022 whose data were extracted from an international consortium and compared with a cohort of patients with CP-B receiving BSC. Patients were treated in tertiary care centers across Europe, US, and Asia in routine clinical practice. After applying the inclusion criteria, 187 and 156 patients were left in the ICI and BSC groups, respectively. The propensity score was calculated for the following variables: age, alpha-fetoprotein levels, Child-Pugh score, extrahepatic spread, portal vein tumor thrombosis, cirrhosis, ascites, and baseline Eastern Cooperative Oncology Group performance status. Patients in the ICI group received first-line systemic therapy with either atezolizumab plus bevacizumab (A+B) (n = 141) or nivolumab (n = 46). OS in the inverse probability of treatment weighting (IPTW) populations was the main outcome, and it was estimated with Kaplan-Meier method; univariable Cox regression test was used to make comparisons between the 2 groups. The median age was 66 (IQR, 61-72) and 73 (IQR, 66-81) years in the ICI (33 women [18%]) and BSC groups (41 women [26%]), respectively. In the IPTW populations, median OS was significantly longer in the ICI group (7.50 months; 95% CI, 5.62-11.15) compared with BSC (4.04 months; 95% CI, 3.03-5.03; hazard ratio, 0.59; 95% CI, 0.43-0.80; P < .001). Multivariable analysis confirmed that ICI exposure was associated with a reduction of approximately 50% in the risk of death (hazard ratio, 0.55; 95% CI, 0.35-0.86; P < .001), and the presence of portal vein tumor thrombosis, an Eastern Cooperative Oncology Group performance score of greater than 1, and alpha-fetoprotein levels of 400 ng/mL or greater were associated with increased risk of death. The results of this case series provide comparative evidence of improved survival in association with ICI treatment compared with BSC in patients with uHCC with CP-B liver dysfunction.

Efficacy and safety of a novel weekly topical metformin loaded peel-off-mask in the treatment of melasma: a split face, placebo-controlled study.

Melasma is a widely common condition that intractably affects the patient's quality of life. Metformin is a cheap, well tolerated, and relatively safe medication that is widely prescribed for the treatment of Diabetes. Topical metformin has shown promising results in treating melasma, as well as several other dermatological conditions such as acne and recalcitrant central centrifugal cicatricial alopecia. to study the efficacy and safety of a once weekly topical metformin 30% loaded peel-off mask in treating of melasma. Twenty female patients with melasma were recruited for the application of a metformin mask and placebo mask to either side of the face once weekly for 12 weeks. Hemi-MASI was calculated at baseline, at each visit, and 12 weeks after the end of treatment. At baseline, the hemi-MASI score matched between both metformin and placebo sides (708±2.62 & 7.08±2.62 respectively (p = 1). At the end of the active treatment period, the metformin side showed a significantly better improvement in hemi-MASI score in comparison to placebo (68%±0.23 improvement on the metformin side in contrast to 20%± 0.176 on the placebo side). Although scores decreased 3 months after stopping the active treatment (52%±0.23 improvement on the metformin side compared to the placebo side 15%±0.197), they were still significantly better than the baseline. No adverse effects were reported. Topical metformin loaded peel-off mask can be a promising, safe, and effective treatment for melasma. Although applied once weekly, metformin peel-off mask shows comparable efficacy to previously reported daily usage formulations.

Changes in Cerebrospinal Fluid Concentrations of Selenium Species Induced by Tofersen Administration in Subjects with Amyotrophic Lateral Sclerosis Carrying SOD1 Gene Mutations.

Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease affecting the brain and spinal cord motor neurons. On 25 April 2023, the drug tofersen, an antisense oligonucleotide, received the US Food and Drug Administration approval for treating ALS in adults carrying mutations of the SOD1 gene. We aimed at assessing whether cerebrospinal fluid concentrations of selenium, an element of both toxicological and nutritional interest possibly involved in disease etiology and progression, are modified by tofersen administration. We determined concentrations of selenium species by anion exchange chromatography hyphenated to inductively coupled plasma-dynamic reaction cell-mass spectrometry and overall selenium by using inductively coupled plasma sector-field mass spectrometry, at baseline and 6months after active tofersen treatment in ten Italian ALS patients carrying the SOD1 gene mutation. Concentrations of total selenium and many selenium species substantially increased after the intervention, particularly of inorganic (tetravalent and hexavalent) selenium and of the organic species selenomethionine and a compound co-eluting with the selenocystine standard. Overall, these findings suggest that tofersen treatment markedly alters selenium status and probably the redox status within the central nervous system, possibly due to a direct effect on neurons and/or the blood-brain barrier. Further studies are required to investigate the biological and clinical relevance of these findings and how they might relate to the pharmacological effects of the drug and to disease progression.

Circulating 25-hydroxycholecalciferol and calcium levels, and alkaline phosphatase activity among people living with and without human immunodeficiency virus and injecting drugs in kenya

Background People who inject drugs (PWID) and living with the human immunodeficiency virus (PLHIV) are at higher risk of suffering marked derangements in micronutrient levels, leading to poor disease and treatment outcomes. Consequently, this can be monitored by measuring key biomarkers, such as total circulating (serum) 25-hydroxycholecalciferol (25(OH)D3), calcium, and alkaline phosphatase (ALP) for timely intervention. Therefore, circulating levels of 25(OH)D3 and calcium, and ALP activity were determined in PWID and are highly active anti-retroviral treatment (HAART)-experienced or -naive, along with those without HIV infection.MethodsThis cross-sectional study compared serum concentrations of 25(OH)D3, calcium, and ALP in Kenyan PLHIV and were HAART-naive (n = 30) or -experienced (n = 61), PWID and without HIV (n = 132).Results Circulating 25(OH)D3 levels were significantly different amongst the study groups (P < 0.001), and were significantly lower in the HAART-experienced (median, 17.3; IQR, 18.3 ng/ml; P < 0.001) and -naive participants (median, 21.7; IQR, 12.8 ng/ml; P = 0.015) relative to uninfected (median, 25.6; IQR, 6.8 ng/ml) PWID. In addition, the proportions of vitamin D deficiency (55.7%, 40.0%, and 17.4%) and insufficiency (31.1%, 53.3%, and 63.6%) compared to sufficiency (13.1%, 6.7%, and 18.9%; P < 0.001) were greater amongst HAART-experienced, -naive, and uninfected study groups, respectively. Likewise, serum total calcium concentrations were lower in the HAART-experienced relative to HIV-negative (P = 0.019) individuals. Serum ALP activity was also lower in the HAART-experienced in contrast to HIV-negative PWID (P = 0.048). Regression analysis indicated that predictors of circulating 25(OH)D3 were: age (β = 0.287; R2 = 8.0%; P = 0.017) and serum ALP (β = 0.283; R2 = 6.4%; P = 0.033) in the HAART-experienced PWID, and serum ALP (β = 0.386; R2 = 14.5%; P < 0.001) in the HIV-negative PWID.Conclusion This study suggests that HIV-1 infection and HAART, including injection substance use, decrease circulating 25(OH)D3, calcium and ALP activity. In addition, age and ALP activity are associated with low circulating vitamin D levels in HAART-experienced PWID. The results highlight the importance of incorporating vitamin D and calcium supplementation in treatment and rehabilitation protocols for PLHIV.

Patient-reported convenience and effectiveness of telehealth for breast cancer management.

Before the coronavirus disease 2019 (COVID-19) pandemic, telehealth was rarely used for breast cancer management at tertiary care centers. We sought to examine patient satisfaction, experiences, preferences, and perceived effectiveness and technical quality of telehealth visits in follow-up patients receiving routine outpatient care in the breast medical oncology practice at The University of Texas MD Anderson Cancer Center. We administered a survey to 60 follow-up patients for a duration of 9 months (January 5, 2021 to October 27, 2021) who had at least one telehealth consultation during the COVID-19 pandemic, from April 10, 2020 to October 21, 2021. Descriptive statistics were then generated for each question, each domain, and overall survey scores. Subgroup comparisons within patient populations were done using the chi-square or t-test when appropriate. Among the 60 participants, 49 (82%) were undergoing standard follow-up during active treatment for either early-stage or metastatic breast cancer. Telehealth and in-person office visits were considered equivalent in terms of quality of communication by 43 participants (72%). Most participants (n = 49, 82%) felt equally cared for during telehealth and in-person visits, and 40 participants (67%) reported feeling connected to their healthcare professional during both telehealth and in-person visits. In addition, 28 participants (47%) felt that the duration of telehealth visits was similar to in-person visits, 46 (77%) found both telehealth and in-person visits equally comfortable for discussing sensitive topics, 39 (65%) considered telehealth visits convenient, and 42 (70%) perceived the overall quality of care for telehealth to be similar to that of in-person visits. Participants expressed high satisfaction with telehealth appointments, with 42 (70%) rating their experience as very satisfying. Most participants (n = 44, 73%) expressed a strong likelihood of participating in telehealth appointments for breast cancer follow-up care in the future. Our results indicate that telehealth can serve as an effective and satisfactory approach for delivering healthcare services to patients with breast cancer requiring follow-up care. The positive experiences and willingness to continue using telehealth indicate its potential for improving access to care and patient outcomes.

Patient adherence in orthodontics: a scoping review

ABSTRACTBackgroundPatient adherence is a key factor in achieving orthodontic treatment success. Despite an evolution in orthodontic healthcare, no recent comprehensive reviews are available on patient adherence in orthodontics. This scoping review provides an evidence-based overview of the literature available on multiple aspects of patient adherence in orthodontics, during both active treatment as well as during the retention phase. Knowledge gaps identified in the literature are listed.MethodsThe protocol for this scoping review was registered in the Open Science Framework (https://doi.org/10.17605/OSF.IO/EC6QD). Electronic databases and reference lists of relevant studies were searched up to 9 February 2023. The inclusion criteria were studies investigating any form of patient adherence in orthodontics published in English from 2006 onwards. The exclusion criteria were studies investigating adherence in the following patients: those with an intellectual or physical disability that could affect their ability to coincide with their therapist’s recommendations and advice, those with oral cleft and craniofacial conditions, and those treated solely for obstructive sleep apnoea. Non-peer-reviewed studies and case reports were also excluded.ResultsA total of 3284 articles were identified, 60 of which met the criteria for final inclusion.ConclusionsThere is no conclusive evidence on which factors have a significant impact on patient adherence and how patient adherence can be promoted. The degree of patient adherence is generally not compared to achieved treatment results or stability of treatment results, making it difficult to provide clear statements about the impact of the degree of adherence on desired treatment results or orthodontic stability.

Subsequent biologic and targeted synthetic disease modifying anti rheumatic drugs after fulfilling difficult-to-treat rheumatoid arthritis criteria: a survival analysis.

To evaluate the survival of different biologic or targeted-synthetic disease-modifying antirheumatic drugs (b/tsDMARD) administered after fulfilling difficult-to-treat rheumatoid arthritis (D2TRA) criteria, and to assess factors related to treatment discontinuation. Retrospective study including D2TRA patients. Drug retention of the b/tsDMARD administered after fulfilling D2TRA was assessed by Kaplan-Meier plots and the log-rank test. Cox hazard models were used to identify factors affecting treatment discontinuation. Of the 122 patients included, 75 maintained active treatment (61.5%) with a subsequent line after D2T compared to 47 (38.5%) who discontinued and required more successive lines of b/tsDMARDs. The median survival of the treatments was 78.3(7.6) months and the treatment after D2T with the better rate of survival was rituximab, followed by JAKi and IL6Ri, while worse survival rates were associated with abatacept and TNFi. Significant differences were noted among b/tsDMARDs (log-rank p < 0.01) and to evaluate these differences, a Cox regression was performed, taking each b/tsDMARD as a reference and comparing it with the others. DAS28 values 6-months after initiation of treatment were higher in those patients who discontinued treatment [4.4(1.2) vs 3.5(1.3), p = 0.01]. The multivariate cox regression model revealed that treatment choice after D2T [HR = 1.26(95%CI 1.06-1.05)] and lower DAS28 values at 6 months [HR = 1.49(95%CI 1.16-1.52)] were independent risk factors associated with treatment discontinuation. Once patients met the D2TRA criteria, the subsequent line of b/tsDMARDs with the best survival rates were rituximab, JAKi and IL6Ri. Moreover, DAS28 at 6-months of treatment after D2T was an independent risk factor for drug discontinuation. Key Points • Rituximab, IL6Ri and JAKi have better retention ratesin patients after fulfilling D2TRA criteria • Clinical disease activity in the first six months after fulfillment of D2TRA criteria is an independent risk factor of subsequent treatment survival.

Vaccine challenges in CLL: a comprehensive exploration of efficacy of SARS-CoV-2 immunization for patients with chronic lymphocytic leukemia.

Chronic lymphocytic leukemia (CLL) is characterized by disease- and treatment-related immunosuppression. Patients with CLL comprise a vulnerable population to coronavirus disease 2019 (COVID-19), while the protective effect of COVID-19 vaccination remains uncertain.We conducted a systematic review to evaluate published data reporting response to COVID-19 vaccination in patients with CLL. The primary outcome was the rate of seropositivity after full primary vaccination, while secondary outcomes were rates of positive neutralizing antibodies, cellular responses, and adverse events. Response after booster doses of vaccination was also evaluated.Twenty-three studies of full primary vaccination (12 CLL-specific with 1747 patients, 11 with mixed hematologic diseases including 1044 patients with CLL) with a total of 2791 patients, and eight studies on booster doses with 389 patients were included in the analysis. The serologic response varied between studies with a median of 55%. Where reported, the median neutralizing antibody response rate was 61.2% and the cellular response rate was 44.2%. Poor serologic response was noted in patients under active treatment with anti-CD20 monoclonal antibodies, BCL2, and BTK inhibitors.The present review highlights the substantially impaired humoral and cellular response to COVID-19 vaccination in patients with CLL with patients under active treatment being the most vulnerable.

Changes in Astigmatism after Surgery in Pediatric Patients with Limbal Dermoid

Purpose: To analyze changes in astigmatism and visual acuity in pediatric patients with limbal dermoid before and after surgery.Methods: Twenty-five pediatric patients (7 male, 18 female) diagnosed with limbal dermoid from March 2018 to February 2022 were included. We analyzed best corrected visual acuity and astigmatism using cycloplegic refraction, automated keratometry, and topography before and after surgery.Results: In cycloplegic refraction and automated keratometry, postoperative astigmatism did not decrease significantly (&lt;i&gt;p&lt;/i&gt; = 0.53 and &lt;i&gt;p&lt;/i&gt; = 0.38, respectively). Topography showed a significant decrease in corneal astigmatism from 3.6 ± 2.8 diopters (D) to 2.7 ± 1.8 D (&lt;i&gt;p&lt;/i&gt; &lt; 0.05) and in irregular astigmatism from 3.7 ± 2.2 D to 2.5 ± 1.5 D (&lt;i&gt;p&lt;/i&gt; &lt; 0.001). Significant decreases were observed in the corneal irregularity index from 0.14 ± 0.10 mm to 0.08 ± 0.47 mm (&lt;i&gt;p&lt;/i&gt; &lt; 0.001) and in the index of surface variance from 60.56 ± 41.02 to 35.00 ± 16.00 (&lt;i&gt;p&lt;/i&gt; &lt; 0.001). There was a statistically significant improvement in best corrected visual acuity from logarithm of minimal angle of resolution (logMAR) 0.18 to logMAR 0.07 (&lt;i&gt;p&lt;/i&gt; &lt; 0.05).Conclusions: Surgery for limbal dermoid significantly reduced irregular astigmatism and improved best-corrected visual acuity. It is suggested that achieving visual development through active amblyopia treatment after surgery is important.

Management of Cytomegalovirus Infection in Allogeneic Hematopoietic Stem Cell Transplant Recipients

Cytomegalovirus (CMV) is a type of double-stranded deoxyribonucleic acid virus belonging to the herpesviridae family. Following a primary infection, the virus becomes latent in various types of white blood cells. Cytomegalovirus infection can remain latent or become active, especially in immunocompromised individuals, such as those undergoing hematopoietic stem cell transplantation (HSCT), where CMV reactivation can occur. In this context, CMV infection is common and associated with high rates of morbidity and mortality. Pneumonia is one of the most serious complications, with mortality rates exceeding 50%. Additionally, even in the absence of organ-specific disease, CMV infection is related to increased mortality unrelated to hematologic neoplasm recurrence. Given the frequency and severity of this infection in HSCT patients, it is crucial to implement effective strategies for monitoring, prevention, and treatment. This guideline was developed to identify patient groups that benefit from a systematic approach to CMV infection and to define the most appropriate strategy for each group. Monitoring CMV viral load in peripheral blood is crucial, especially in patients at moderate to high risk of active infection. Primary prophylaxis with letermovir (an antiviral drug) is recommended to reduce the incidence of active infection, especially in high-risk patients. Secondary prophylaxis with valganciclovir (antiviral drug) is recommended after an episode of active infection, while preemptive and disease treatment is based on monitoring viral load and clinical response. The aim of this guideline is to improve the approach to CMV infection in HSCT patients, ensuring an effective and safe preventive and therapeutic approach.

A systematic review on artificial intelligence evaluating PSMA PET scan for intraprostatic cancer.

To assess artificial intelligence (AI) ability to evaluate intraprostatic prostate cancer (PCa) on prostate-specific membrane antigen positron emission tomography (PSMA PET) scans prior to active treatment (radiotherapy or prostatectomy). This systematic review was registered on the International Prospective Register of Systematic Reviews (PROSPERO identifier: CRD42023438706). A search was performed on Medline, Embase, Web of Science, and Engineering Village with the following terms: 'artificial intelligence', 'prostate cancer', and 'PSMA PET'. All articles published up to February 2024 were considered. Studies were included if patients underwent PSMA PET scan to evaluate intraprostatic lesions prior to active treatment. The two authors independently evaluated titles, abstracts, and full text. The Prediction model Risk Of Bias Assessment Tool (PROBAST) was used. Our search yield 948 articles, of which 14 were eligible for inclusion. Eight studies met the primary endpoint of differentiating high-grade PCa. Differentiating between International Society of Urological Pathology (ISUP) Grade Group (GG) ≥3 PCa had an accuracy between 0.671 to 0.992, sensitivity of 0.91, specificity of 0.35. Differentiating ISUP GG ≥4 PCa had an accuracy between 0.83 and 0.88, sensitivity was 0.89, specificity was 0.87. AI could identify non-PSMA-avid lesions with an accuracy of 0.87, specificity of 0.85, and specificity of 0.89. Three studies demonstrated ability of AI to detect extraprostatic extensions with an area under curve between 0.70 and 0.77. Lastly, AI can automate segmentation of intraprostatic lesion and measurement of gross tumour volume. Although the current state of AI differentiating high-grade PCa is promising, it remains experimental and not ready for routine clinical application. Benefits of using AI to assess intraprostatic lesions on PSMA PET scans include: local staging, identifying otherwise radiologically occult lesions, standardisation and expedite reporting of PSMA PET scans. Larger, prospective, multicentre studies are needed.

Efficacy and tolerability of monoamine oxidase inhibitors for the treatment of depressive episodes in mood disorders: A systematic review and network meta-analysis.

Monoamine oxidase inhibitors (MAOIs) are considered third-line treatments for treatment resistant depression; however, they are underused in clinical practice. This study aimed to assess the efficacy, tolerability, and acceptability of MAOIs for the treatment of depression in comparison with other antidepressant treatments. A systematic review and network meta-analysis of randomised clinical trials was performed to compare the efficacy, tolerability and acceptability between MAOIs and other antidepressant treatments for the treatment of depressive episodes. A total of 83 double-blinded, randomised controlled trials were included in the analysis, with 7765 participants assigned to an active treatment and 1844 assigned to placebo. Several MAOIs, including isocarboxazid, phenelzine, tranylcypromine and moclobemide, showed significantly higher efficacy compared with placebo. The tolerability and acceptability of MAOIs was comparable to other antidepressants. A disproportionate number of studies investigating the most commonly used MAOIs, such as moclobemide and phenelzine, and a lack of specific studies focusing on treatment-resistant and atypical depression. MAOIs are similar in efficacy to other antidepressants for the treatment of depression. However, more studies are needed comparing MAOI treatment in people with treatment-resistant, atypical and bipolar depression.

Clinical characteristics of membranous nephropathy after allogeneic hematopoietic stem cell transplantation: Areal-world multicenter study.

Membranous nephropathy (MN) is a rare complication that can occur after allogeneic hematopoietic stem cell transplantation (allo-HSCT). MN patients may develop nephrotic syndrome or even kidney failure, which greatly affects their quality of life and prognosis. However, current knowledge regarding MN after allo-HSCT is limited. Thus, a multicenter nested case‒control study was conducted. Patients who had been diagnosed with MN after allo-HSCT were retrospectively identified at 8 HSCT centers. A total of 51 patients with MN after allo-HSCT were included. The median age of MN patients after allo-HSCT was 38 years, and the median duration from HSCT to MN was 18 months. The use of HLA-matched donors (P = 0.0102) and peripheral blood as the graft source (P = 0.0060) were identified as independent predisposing risk factors for the onset of MN after allo-HSCT. Compared to those in the control group, the incidence of extensive chronic graft-versus-host disease was greater in the MN patients (P = 0.0002). A total of 31 patients developed nephrotic syndrome. Patients receiving combination treatments of corticosteroids and immunosuppressants appeared to have better outcomes. In conclusion, MN is a rare but occasionally severe complication following HSCT and may require active treatment.

The safety and effectiveness of naldemedine for opioid-induced constipation in patients with advanced cancer in real-world palliative care settings: a multicenter prospective observational study.

In this study, we aimed to evaluate the safety and effectiveness of naldemedine for treating opioid-induced constipation (OIC) in patients with advanced cancer, who are receiving palliative care, and particularly explored its early effects. Palliative care teams and inpatient palliative care units across 14 institutions in Japan were included in this multicenter, prospective, observational study. Patients who were newly prescribed a daily oral dose of 0.2mg naldemedine were enrolled. The spontaneous bowel movement (SBM) within 24h after the first dose of naldemedine was considered the primary outcome, whereas, the secondary outcomes included weekly changes in SBM frequency and adverse events. A total of 204 patients were enrolled and 184 completed the 7-day study. The average age of the participants (103 males, 101 females) was 63 ± 14years. The primary cancer was detected in the lungs (23.5%), gastrointestinal tract (13.7%), and urological organs (9.3%). A considerable proportion of patients (34.8%) had ECOG performance status of 3-4. Most patients were undergoing active cancer treatment, however, 40.7% of the patients were receiving the best supportive care. Within 24h of the first naldemedine dose, 146 patients (71.6%, 95% CI: 65.4-77.8%) experienced SBMs. The weekly SBM counts increased in 62.7% of the participants. The major adverse events included diarrhea and abdominal pain, detected in 17.6% and 5.4% of the patients, respectively. However, no serious adverse events were observed. Conclusively, naldemedine is effective and safe for OIC treatments in real-world palliative care settings. UMIN000031381, registered 20/02/2018.

Feedback and Financial Incentives for Reducing Cell Phone Use While Driving

Handheld phone use while driving is a major factor in vehicle crashes. Scalable interventions are needed to encourage drivers not to use their phones. To test whether interventions involving social comparison feedback and/or financial incentives can reduce drivers' handheld phone use. In a randomized clinical trial, interventions were administered nationwide in the US via a mobile application in the context of a usage-based insurance program (Snapshot Mobile application). Customers were eligible to be invited to participate in the study if enrolled in the usage-based insurance program for 30 to 70 days. The study was conducted from May 13 to June 30, 2019. Analysis was completed December 22, 2023. Participants were randomly assigned to 1 of 6 trial arms for a 7-week intervention period: (1) control; (2) feedback, with weekly push notification about their handheld phone use compared with that of similar others; (3) standard incentive, with a maximum $50 award at the end of the intervention based on how their handheld phone use compared with similar others; (4) standard incentive plus feedback, combining interventions of arms 2 and 3; (5) reframed incentive plus feedback, with a maximum $7.15 award each week, framed as participant's to lose; and (6) doubled reframed incentive plus feedback, a maximum $14.29 weekly loss-framed award. Proportion of drive time engaged in handheld phone use in seconds per hour (s/h) of driving. Analyses were conducted with the intention-to-treat approach. Of 17 663 customers invited by email to participate, 2109 opted in and were randomized. A total of 2020 drivers finished the intervention period (68.0% female; median age, 30 [IQR, 25-39] years). Median baseline handheld phone use was 216 (IQR, 72-480) s/h. Relative to control, feedback and standard incentive participants did not reduce their handheld phone use. Standard incentive plus feedback participants reduced their use by -38 (95% CI, -69 to -8) s/h (P = .045); reframed incentive plus feedback participants reduced their use by -56 (95% CI, -87 to -26) s/h (P < .001); and doubled reframed incentive plus feedback participants reduced their use by -42 s/h (95% CI, -72 to -13 s/h; P = .007). The 5 active treatment arms did not differ significantly from each other. In this randomized clinical trial, providing social comparison feedback plus incentives reduced handheld phone use while individuals were driving. ClinicalTrials.gov Identifier: NCT03833219.

Laparoscopic Extended Segmentectomy VIII Guided by Three-Dimensional Reconstruction and Hepatic Veins with a Cranio-Caudal Approach.

Minimally invasive resection of segment VIII is a technically challenging procedure, made even more challenging when the resection is extended to segment IV and/or segment VII. Parenchymal-sparing resections are frequently used in the management of liver metastases but expose to the risk of R1 resection, especially with a minimally invasive approach. Preoperative surgical planning with 3D reconstruction and intraoperative guidance with hepatic vein is helpful for laparoscopic oncological liver resection.1-3 PATIENT AND METHODS: We present the case of a 58-year-old female with three metachronous liver metastases from epidermoid anal cancer. The disease was stable 6 months after cessation of chemotherapy. Metastases were mainly located in segment VIII (with a large segment VIII dorsal) but also in the territory of glissonian pedicles from segments IV and VII. Prior to surgery, three-dimensional (3D) reconstruction showed that a segmentectomy VIII would not be sufficient to have a safety margin and showed the relation between metastases and hepatic veins. Transection of the liver was performed with an ultrasonic dissector. Exposure of the hepatic veins was performed by gently pulling of the hepatic tissue from the vein, using the nonactive blade of the ultrasonic device. Activation of ultrasonic energy was performed only for sealing and dividing small collateral veins. Three transection lines were necessary. The posterior transection line, in segment VII, was determined with intraoperative ultrasound (IOUS), at 1 cm below the metastasis. The liver was transected superficially only. The medial transection line, in segment IV, was determined with IOUS, at 1cm on the left of the metastasis, parallel to the middle hepatic vein. Finally, the inferior transection line, between segment V and segment VIII, was approximately determined with IOUS, vertically aligned with the hepatic vein of segment V. The transection line was further corrected after clamping the glissonian pedicle of segment VIII, according to fluorescence. The surgical procedure began with the mobilization of the right liver, including division of the hepato-caval ligament, followed by the superficial transection of the posterior margin in segment VII. Then, transection of segment IV was performed near the termination of the middle hepatic vein, which was further exposed with a cranio-caudal approach to minimize the risk of vein injury. The hepatic vein of segment V was then used as a landmark for the identification of the Glissonian pedicle of segment VIII, which was transected.4 Termination of the right hepatic vein (RHV) was then identified, and the ventral branch of the RHV was transected. The dorsal branch of the RHV was exposed with a cranio-caudal approach. Finally, transection of segment VII was performed toward the transection line made initially. Operative time was 360 min with 450 mL blood loss. The Pringle maneuver was used during 148 min. The patient was discharged on the seventh postoperative day. Pathological examination confirmed R0 resection, with 20-60% necrosis of the three liver metastases. The resected liver weight was 225 g. Six months after liver resection, the patient had a recurrence in a celiac lymph node, which was treated by radiotherapy. Fifteen months after liver resection, the patient is free of disease without active treatment. Preoperative virtual hepatectomy facilitates surgical planning by increasing the understanding of the tumors-vessels relationship. Intraoperative hepatic vein guidance with a cranio-caudal approach enables to follow preoperative surgical planning and to perform safe complex laparoscopic liver resection.

Treatment of Active Crohn's Disease With Exclusive Enteral Nutrition Diminishes the Immunostimulatory Potential of Fecal Microbial Products.

Exclusive enteral nutrition (EEN) is an effective treatment for active Crohn's disease (CD). This study explored the immunostimulatory potential of a cell-free fecal filtrate and related this with changes in the fecal microbiota and metabolites in children with active CD undertaking treatment with EEN. Production of tumor necrosis factor α (TNFα) from peripheral blood mononuclear cells was measured following their stimulation with cell-free fecal slurries from children with CD, before, during, and at completion of EEN. The metabolomic profile of the feces used was quantified using proton nuclear magnetic resonance and their microbiota composition with 16S ribosomal RNA sequencing. Following treatment with EEN, 8 (72%) of 11 patients demonstrated a reduction in fecal calprotectin (FC) >50% and were subsequently labeled FC responders. In this subgroup, TNFα production from peripheral blood mononuclear cells was reduced during EEN (P = .008) and reached levels like healthy control subjects. In parallel to these changes, the fecal concentrations of acetate, butyrate, propionate, choline, and uracil significantly decreased in FC responders, and p-cresol significantly increased. At EEN completion, TNFα production from peripheral blood mononuclear cells was positively correlated with butyrate (rho = 0.70; P = .016). Microbiota structure (β diversity) was influenced by EEN treatment, and a total of 28 microbial taxa changed significantly in fecal calprotectin responders. At EEN completion, TNFα production positively correlated with the abundance of fiber fermenters from Lachnospiraceae_UCG-004 and Faecalibacterium prausnitzii and negatively with Hungatella and Eisenbergiella tayi. This study offers proof-of concept data to suggest that the efficacy of EEN may result from modulation of diet-dependent microbes and their products that cause inflammation in patients with CD.

Preparation and Performance Analysis of New Multi stage Porous Carbon Materials for Air Pollution Treatmentials on Atmospheric Pollution Sources under the Background of Carbon Peak and Carbon Neutrality

The adsorption of toxic and harmful gases through porous materials is an effective means of air pollution control. A multi-level porous carbon material with ultra-high-specific surface area was made based on rice husk biomass to improve the air pollution controlling efficiency and reduce its cost. The rice husk substrate was pretreated using T.viride spore suspension during the preparation of this material. This changes the proportion of various components in the matrix, thereby achieving an increase in the multi-level porous carbon material’s specific surface area. Its performance was analyzed through various means in the study. The results confirmed that when the activation treatment time was 60 minutes, the porous carbon material’s specific surface area was the highest, reaching 3714 m2/g. After 30 days of treatment with T.viride spore suspension, the cellulose content in rice husks decreased by about 40 g/kg. Compared to untreated porous carbon materials, after 20 days of treatment, the micropores and mesopores of these materials significantly increased. The research has successfully increased the multi-level porous carbon material’s specific surface area and achieved rapid absorption of atmospheric volatile organic compounds. The multi-level porous carbon material can enhance the air pollution controlling efficiency and reduce its cost.

Implementation factors of tuberculosis control program in primary healthcare settings in China: a mixed-methods using the Consolidated Framework for Implementation Research framework.

Tuberculosis (TB) is a major cause of death worldwide, and Chinese TB burden ranked the second globally. Chinese primary healthcare (PHC) sectors implement the TB Control Program (TCP) to improve active case finding, referral, treatment adherence, and health education. This study aimed to identify barriers and enablers of TCP implementation in high TB burden regions of West China. We conducted a representative study using mixed-methods in 28 counties or districts in Chongqing Municipality and Guizhou Province of West China from October 2021 to May 2022. Questionnaire surveys and semi-structured in-depth interviews were conducted with 2720TB healthcare workers (HCWs) and 20 interviewees in PHC sectors. Descriptive statistical analysis was used to investigate TB HCWs' characteristics, and path analysis model was utilized to analyze the impact of associated factors on TCP implementation. Thematic framework analysis was developed with the guide of the adapted Consolidated Framework for Implementation Research (CFIR) on factors of TCP implementation. This study found that 84.6% and 94.1% of community and village HCWs had low professional titles. Based on the results of multiple regression analysis and correlation analysis, lower TB core knowledge scores (-0.09) were identified as barriers for TCP implementation in community PHC sectors, and low working satisfaction (-0.17) and low working willingness (-0.10) are barriers for TPC implementation in village PHC sectors. The results of in-depth interviews reported barriers in all domains and enablers in four domains of CFIR. There were identified 19 CFIR constructs associated with TCP implementation, including 22 barriers such as HCWs' heavy workload, and 12 enablers such as HCWs' passion towards TCP planning. With the guide of the CFIR framework, complex factors (barriers and enablers) of TCP implementation in PHC sectors of West China were explored, which provided important evidences to promote TB program in high TB burden regions. Further implementation studies to translate those factors into implementation strategies are urgent needed.

Revealing the mechanisms of blood-brain barrier in chronic neurodegenerative disease: an opportunity for therapeutic intervention.

The brain microenvironment is tightly regulated, and the blood-brain barrier (BBB) plays a pivotal role in maintaining the homeostasis of the central nervous system. It effectively safeguards brain tissue from harmful substances in peripheral blood. However, both acute pathological factors and age-related biodegradation have thepotential to compromise the integrity of the BBB and areassociated with chronic neurodegenerative diseases such as Alzheimer's disease (AD) and Parkinson's disease (PD), as well as Epilepsy (EP). This association arises duetoinfiltration of peripheral foreign bodies including microorganisms, immune-inflammatory mediators, and plasma proteins into the central nervous system when the BBB is compromised. Nevertheless, these partial and generalized understandings do not prompt a shift from passive to active treatment approaches. Therefore, it is imperative to acquire a comprehensive and in-depth understanding of the intricate molecular mechanisms underlying vascular disease alterations associated with theonset and progression of chronic neurodegenerative disorders, as well as the subsequent homeostatic changes triggered by BBB impairment. The present article aims to systematically summarize and review recent scientific workwith a specific focus on elucidating the fundamental mechanisms underlying BBB damage in AD, PD, and EP as well as their consequential impact on disease progression. These findings not only offer guidance for optimizing thephysiological function of the BBB, but also provide valuable insights for developing intervention strategies aimed at early restoration of BBB structural integrity, thereby laying a solid foundation for designing drug delivery strategies centered around the BBB.
