Authors: Sun Yanxia , Liang Xuan , Chai Fang , Shi Dongjing , Wang Yue 
Published: December 2023

Abstract
Background and objective
The effectiveness of goal-directed fluid therapy (GDFT) in promoting postoperative recovery remains unclear, the aim of this study was to evaluate the effect of GDFT on length of hospital stay and postoperative recovery of GI function in patients undergoing major abdominal oncologic surgery.

Methods
In this randomized, double- blinded, controlled trial, adult patients scheduled for elective major abdominal surgery with general anesthesia, were randomly divided into the GDFT protocol (group G) or conventional fluid therapy group (group C). Patients in group C underwent conventional fluid therapy based on mean arterial pressure (MAP) and central venous pressure (CVP) whereas those in group G received GDFT protocol associated with the SVV less than 12% and the cardiac index (CI) was controlled at a minimum of 2.5 L/min/m2. The primary outcomes were the length of hospital stay and postoperative GI function.

Results
One hundred patients completed the study protocol. The length of hospital stay was significantly shorter in group G compared with group C [9.0 ± 5.8 days versus 12.0 ± 4.6 days, P = 0.001]. Postoperative gastrointestinal dysfunction (POGD) occurred in two of 50 patients (4%) in group G and 16 of 50 patients (32%) in the control group (P < 0.001). GDFT significantly also shorten time to first flatus by 11 h (P = 0.009) and time to first tolerate oral diet by 2 days (P < 0.001).

Conclusions
Guided by SVV and CI, the application of GDFT has the potential to expedite postoperative recovery of GI function and reduce hospitalization duration after major abdominal surgery.

Published: December 2023

Abstract
Background
Aging is associated with many personal, social, and environmental challenges that increase the risk of loneliness. Loneliness is a painful emotional experience associated with a perceived lack of connection and intimacy. Loneliness accelerates health deterioration, but the presence of chronic health conditions (comorbidities) in older individuals may potentiate the feeling of loneliness. The relationships between health status and loneliness in older individuals have not been assessed in an integrated manner, although it is necessary for planning efficient interventions. The aim of this study was to fill in this knowledge gap, by attempting to create an integrated model of loneliness in older individuals.

Methods
The sample consisted of 189 (58% F) older individuals (> 60 years) (mean ± SD, 78.47 ± 6.65), attendees in Primary Health Care. Different factors associated with loneliness in the older population were assessed, and classified as demographic, environmental, physical (health-related), and psychological, in addition to functional abilities. A set of standard questionnaires was used to assess psychological factors and functional abilities. The hierarchical regression model assessed the effect of particular blocks of factors on status loneliness. The second aim was to analyze how psychological factors mediate associations between health status (comorbidity level) and loneliness.

Results
Indicated that increasing comorbidity, anxiety, lack of positive moods, not having hobbies/activities, low perception of social support, impaired cognitive function, and suppression of emotion expression, are significant predictors of loneliness. Mediation analysis informed us of how to help patients with comorbidities feel less lonely. Interventions that were suggested were those that can reduce anxiety and depression, improve cognitive abilities and emotional regulation control, and enhance social support.

Conclusions
Results can help understand the pathophysiology loops linking poor health status (comorbidity level) of older individuals and loneliness, and have significant potentials from the translational perspectives, as a decision-support tool.

Published: December 2023

AbstractBackgroundThe Exercise Right for Active Ageing (ERAA) program was established to improve access to exercise classes for community-dwelling older Australians. The aims of this study were to determine whether older adults, who participated in ERAA exercise classes experienced a change in physical function, and identify factors associated with this change.MethodsParticipants included community-dwelling older adults, aged ≥ 65 years, from every state and territory of Australia. The ERAA program included 12 subsidised, weekly, low- to moderate-intensity exercise classes, delivered by accredited exercise scientists or physiologists (AESs/AEPs). Primary outcomes included the 30 s Sit-to-Stand (STS) and the 3-metre Timed Up and Go (TUG) tests. Secondary outcomes included grip strength, the Chair Sit and Reach test, and waist circumference. Linear mixed-effects regression models were used to evaluate the change in outcomes following program completion, and to determine factors associated with changes in the primary outcomes.Results3,582 older adults (77% female) with a median (IQR) age of 72 (69–77) years completed follow-up testing. For all primary and secondary outcomes, there was a statistically significant improvement after program completion (p < 0.001). The STS increased by 2.2 repetitions (95% CI: 2.1, 2.3), the TUG decreased by 0.9 s (95% CI: -1.0, -0.8), right and left grip strength increased by 1.3 kg (95% CI: 1.2, 1.5) and 1.5 kg (95% CI: 1.3, 1.6), respectively, right and left reach increased by 1.7 cm (95% CI: 1.4, 2.0), and waist circumference decreased by 1.2 cm (95% CI: -1.4, -1.1). Greater improvements in STS were observed for participants aged 65–69 years, females, and those with greater socio-economic disadvantage. For the TUG, greater improvements were observed in participants reporting 2 + comorbidities, and residing in outer regional areas and areas with greater socio-economic disadvantage.ConclusionsParticipation of older Australians in the ERAA program, led to statistically significant improvements in physical function. The program reached a large number of older Australians from every state and territory, including those from regional and remote parts of Australia, aged over 85 years, and with high levels of comorbidity, which supports the feasibility and acceptability of AES- and AEP-led exercise classes amongst community-dwelling older Australians.Trial registrationAustralian New Zealand Clinical Trials Registry (ANZCTR) (ACTRN12623000483651).

Published: December 2023

Abstract
Background
The severity of coronavirus disease 2019 (COVID-19) infections has led to the development of several therapeutic agents, with tocilizumab becoming increasingly used to treat patients with COVID-19-related pneumonia. This study compared the use of tocilizumab treatment with the standard of care (SOC) to determine its efficacy against severe COVID-19-related pneumonia in Japan.

Methods
This retrospective cohort study was designed to evaluate the efficacy of tocilizumab in two different databases: the JA42434 single-arm study and COVID-19 Registry Japan (COVIREGI-JP), with a synthetic control group from the COVIREGI-JP cohort as a benchmark for the tocilizumab group. The study’s primary objective was to evaluate the efficacy of tocilizumab in treating severe COVID-19-related pneumonia compared to the SOC among patients included in the above two databases. The SOC group was extracted as the synthetic control group using exact matching and a propensity score matching in sequence per subject. As a secondary objective, the efficacy of tocilizumab compared to the SOC was evaluated exclusively among patients included in the COVIREGI-JP database. In each objective, the primary endpoint was defined as the time to discharge or the status of awaiting discharge.

Results
For the primary endpoint, the hazard ratio (HR) of the tocilizumab group against the SOC group was 1.070 (95% confidence interval [CI]: 0.565–2.028). The median time from Study Day 1 to discharge or the state of awaiting discharge was 15 days in the tocilizumab group and 16 days in the SOC group. The HRs for the secondary endpoints, namely, time to improvement in the clinical state, time to clinical failure, and time to recovery, were 1.112 (95% CI: 0.596–2.075), 0.628 (95% CI: 0.202–1.953), and 1.019 (95% CI: 0.555–1.871), respectively. Similarly, the HR of the primary endpoint for the secondary objective was 0.846 (95% CI: 0.582–1.230).

Conclusions
Tocilizumab did not demonstrate a positive effect on time to discharge or the state of awaiting discharge. Furthermore, no statistically significant differences in other clinical outcomes, such as time to improvement in the clinical state, time to clinical failure, and time to recovery, were observed among the groups.
Incidental multiple myeloma in a patient with neuroretinitis: a case report
Authors: Joo Taesung , Kim Tae Gi , Moon Sang Woong 
Published: December 2023

Abstract
Background
Neuroretinitis is classically defined as a clinical triad of unilateral, painless vision loss, accompanied by optic disc edema and characteristic macular star formation. The causes of neuroretinitis can be categorized as infectious, non-infectious, and idiopathic, therefore differential diagnosis and careful evaluation are required, owing to the various etiologies and masqueraders.

Case presentation
A 54-year-old woman presented to the clinic with blurred vision in both eyes. A complete ophthalmic examination revealed optic disc edema with blurred margins and macular exudates, intraretinal edema in the temporal peripapillary area, and subretinal fluid with neurosensory retinal detachment in the macular area. Systemic laboratory investigations showed no signs of infection or inflammation. However, bone marrow suppression was suspected based on the results of the complete blood count test, and the patient was diagnosed with multiple myeloma.

Conclusion
Although neuroretinitis is rarely accompanied by hematological malignancy, it is important to be mindful of the latter because ophthalmic manifestations are a common feature of hematological malignancies and lesions occur in nearly every ocular structure.
Acceptability of a hypothetical dengue vaccine and the potential impact of dengue vaccination on personal vector control behavior: a qualitative study in Fortaleza, Brazil
Authors: Scott Valerie K. , Pinheiro Maria Suelly Nogueira , Machado Marcia Maria Tavares , Castro Marcia C. 
Published: December 2023

Abstract
Background
Dengue is the most rapidly spreading viral vector-borne disease in the world. Promising new dengue vaccines have contributed to a growing consensus that effective dengue control will require integrated strategies of vaccination and vector control. In this qualitative study, we explored the perspectives of residents of Fortaleza, Brazil on acceptability of a hypothetical safe and effective dengue vaccine, specific drivers of dengue vaccine acceptance or hesitance, and the expected impact of dengue vaccination on their personal vector control practices.

Methods
A total of 43 in-depth interviews were conducted from April to June 2022 with Fortaleza residents from a diverse range of educational and professional backgrounds, with and without recent personal experiences of symptomatic dengue infections. Data were analyzed using the principles of inductive grounded theory methodology.

Results
Our findings indicate that knowledge of dengue transmission, symptoms, and prevention methods was strong across respondents. Respondents described willingness to accept a hypothetical dengue vaccine for themselves and their children, while emphasizing that the vaccine must be demonstrably safe and effective. Respondents expressed diverse perspectives on how receiving a safe and effective dengue vaccine might influence their personal vector control behaviors, relating these behaviors to their perception of risk from other Aedes mosquito-carried infections and beliefs about the role of vector control in maintaining household cleanliness.

Conclusions
Our study findings provide community-level perspectives on dengue vaccination and its potential impact on personal vector control behavior for policymakers and program managers in Fortaleza to consider as new dengue vaccines become available. With the introduction of any new dengue vaccine, community perspectives and emerging concerns that may drive vaccine hesitancy should be continuously sought out. Improved urban infrastructure and efforts to engage individuals and communities in vector control may be needed to optimize the impact of future dengue vaccinations and prevent rising cases of other arboviruses such as Zika and chikungunya.

Published: December 2023

AbstractObjectiveEarly onset of adiposity rebound (AR) is considered an early indicator of obesity risk. Our objective was to investigate the association of birth outcomes and early physical growth patterns with early AR in children.MethodsStudy subjects (n = 2705) were enrolled from the Ma’anshan birth cohort (MABC). The body mass index (BMI), head circumference, waist circumference, and body fat were collected. Rapid weight gain (RWG) was defined by the change in weight standard-deviation score in the first two years of life. Group-based trajectory modeling (GBTM) was used to determine children’s physical growth trajectories. The age of AR was fitted using fractional polynomial function models.ResultsChildren with very high BMI trajectories (RR = 2.83; 95% CI 2.33 to 1.40), rising BMI trajectories (RR = 3.15; 95% CI 2.66 to 3.72), high waist circumference trajectories (RR = 4.17; 95% CI 3.43 to 5.06), and high body fat trajectories (RR = 3.01; 95% CI 2.62 to 3.46) before 72 months of age were at a greater risk of experiencing early AR. Low birth weight (LBW) (RR = 1.86; 95% CI 1.28 to 2.51), preterm birth (PTB) (RR = 1.50; 95% CI 1.17 to 1.93), and small for gestational age (SGA) (RR = 1.37; 95% CI 1.14 to 1.64) associated with increased risk of early AR. Moreover, infants experiencing RWG (RR = 1.59; 95% CI 1.40 to 1.83), low BMI trajectories (RR = 1.27; 95% CI 1.06 to 1.53) and rising BMI trajectories (RR = 1.50; 95% CI 1.22 to 1.84) in the first two years were at higher risk of developing early AR subsequently. Compared to the group with non-early AR, the BMI of children with early AR tended to be lower first (from birth to 6 months of age) and then higher (from 18 to 72 months of age).ConclusionsChildren with overall high BMI, high waist circumference, and high body fat before 72 months of age are more likely to experience early AR, but infants with low BMI trajectories, rising BMI trajectories and infants experiencing RWG in the first two years of life similarly increase the risk of early AR. These results can help to understand the early factors and processes that lead to metabolic risks.

Published: December 2023

Abstract
Background
Goat rumen microbial communities are perceived as one of the most potential biochemical reservoirs of multi-functional enzymes, which are applicable to enhance wide array of bioprocesses such as the hydrolysis of cellulose and hemi-cellulose into fermentable sugar for biofuel and other value-added biochemical production. Even though, the limited understanding of rumen microbial genetic diversity and the absence of effective screening culture methods have impeded the full utilization of these potential enzymes. In this study, we applied culture independent metagenomics sequencing approach to isolate, and identify microbial communities in goat rumen, meanwhile, clone and functionally characterize novel cellulase and xylanase genes in goat rumen bacterial communities.

Results
Bacterial DNA samples were extracted from goat rumen fluid. Three genomic libraries were sequenced using Illumina HiSeq 2000 for paired-end 100-bp (PE100) and Illumina HiSeq 2500 for paired-end 125-bp (PE125). A total of 435gb raw reads were generated. Taxonomic analysis using Graphlan revealed that Fibrobacter, Prevotella, and Ruminococcus are the most abundant genera of bacteria in goat rumen. SPAdes assembly and prodigal annotation were performed. The contigs were also annotated using the DOE-JGI pipeline. In total, 117,502 CAZymes, comprising endoglucanases, exoglucanases, beta-glucosidases, xylosidases, and xylanases, were detected in all three samples. Two genes with predicted cellulolytic/xylanolytic activities were cloned and expressed in E. coli BL21(DE3). The endoglucanases and xylanase enzymatic activities of the recombinant proteins were confirmed using substrate plate assay and dinitrosalicylic acid (DNS) analysis. The 3D structures of endoglucanase A and endo-1,4-beta xylanase was predicted using the Swiss Model. Based on the 3D structure analysis, the two enzymes isolated from goat’s rumen metagenome are unique with only 56–59% similarities to those homologous proteins in protein data bank (PDB) meanwhile, the structures of the enzymes also displayed greater stability, and higher catalytic activity.

Conclusions
In summary, this study provided the database resources of bacterial metagenomes from goat’s rumen fluid, including gene sequences with annotated functions and methods for gene isolation and over-expression of cellulolytic enzymes; and a wealth of genes in the metabolic pathways affecting food and nutrition of ruminant animals.
Efficacy of Kinesio taping in post operative sequalae after surgical removal of mandibular third molars: a split mouth randomized control study
Authors: Patil Sneha , K. Rajanikanth , Bhola Nitin 
Published: December 2023

Abstract
Background
The surgical removal of impacted lower third molars produces a significant degree of trauma to the soft tissue and bony structures of the oral cavity, which can initiate considerable inflammatory reaction. Consequently, patient experiences pain, swelling, hemorrhage, nerve paraesthesia, limited mouth opening etc. The kinesiologic tape (KT) can help with blood and lymphatic circulation and has shown acceptable outcomes in reducing pain and in managing post-operative muscle spasm.

Methodology
The study was aimed to compare the effects of kinesiologic tape on post operative pain, swelling and trismus following surgical removal of mandibular third molar when compared to control group. 15 patients with bilaterally impacted mandibular third molar were included in the split mouth study. One side was randomly assigned as Group A where patient’s face was subjected to Kinesio tape application post extraction. The other was Group B where Kinesio tape was not applied. After extraction each patient was evaluated in terms of post op pain, swelling and trismus in post-op day 1,2 and 7th.

Results
The pain was found to be significantly less (p = 0.042) in group A when compared to group B on the first day. The mean pain was 5.07 in KT group and 6.20 in No KT group on day 2nd. Post OP Swelling was statistically significantly less (p < 0.01) in Group A on 2nd & 3rd day. The postoperative mouth opening was more from the 2nd day in group A with mean of 26.07 mm and 20.33 mm in group B (p < 0.01).

Conclusion
The kinesiologic taping originates from sports medicine, but can also used therapeutically for reducing post operative sequelae as demonstrated in our study. Kinesiologic tape (KT) enables patients to have a comfortable time post-operatively and helps to regain better quality of life.

Authors: Fernandes Juliana O. , Machado Beatriz F. , Cardoso-Filho Cassio , Nativio Juliana , Cabello Cesar , Vale Diama B. 
Published: December 2023

Abstract
Background
This study aims to assess breast cancer survival rates after one decade of mammography in a large urban area of Brazil.

Methods
It is a population-based retrospective cohort of women with breast cancer in Campinas, São Paulo, from 2010 to 2014. Age, vital status and stage were accessed through the cancer and mortality registry, and patients records. Statistics used Kaplan–Meier, log-rank and Cox's regression.

Results
Out of the 2,715 cases, 665 deaths (24.5%) were confirmed until early 2020. The mean age at diagnosis was 58.6 years. Women 50–69 years were 48.0%, and stage I the most frequent (25.0%). The overall mean survival was 8.4 years (8.2–8.5). The 5-year survival (5yOS) for overall, 40–49, 50–59, 60–69, 70–79 years was respectively 80.5%, 87.7%, 83.7%, 83.8% and 75.5%. The 5yOS for stages 0, I, II, III and IV was 95.2%, 92.6%, 89.4%, 71.1% and 47.1%. There was no significant difference in survival in stage I or II (p = 0.058). Compared to women 50–59 years, death's risk was 2.3 times higher for women 70–79 years and 26% lower for women 40–49 years. Concerning stage I, the risk of death was 1.5, 4.1 and 8.6 times higher, and 34% lower, respectively, for stage II, III, IV and 0.

Conclusions
In Brazil, breast cancers are currently diagnosed in the early stages, although advanced cases persist. Survival rates may reflect improvements in screening, early detection and treatment. The results can reflect the current status of other regions or countries with similar health care conditions.
