Published: March 2023

Abstract
Objectives
Neoadjuvant therapy and minimally invasive esophagectomy (MIE) are widely used in the comprehensive treatment of esophageal cancer. This study aimed to investigate the advantages of MIE for esophageal cancer after neoadjuvant therapy.

Methods
Published clinical studies were reviewed and survival data and safety data were extracted. We compared the long-term survival and safety of MIE versus open esophagectomy after neoadjuvant surgery in a series of meta-analyses.

Results
6 retrospective studies were included. Overall, MIE could significantly improve the overall survival of patients with esophageal cancer after neoadjuvant therapy compared with open esophagectomy [hazard ratio (HR) = 0.86, 95% confidence interval (CI) (0.75, 0.98)]. Compared with open esophagectomy, MIE could significantly reduce intraoperative blood loss and operative time [mean difference (MD) = −40.28.78, 95% CI (− 62.98, − 17.58); MD = −28.78, 95% CI (− 42.48, − 15.07), respectively]. There was no significant difference in 30-day and 90-day mortality between MIE and open esophagectomy [odds ratio (OR) = 0.42, 95% CI (0.09, 2.01); OR 0.80, 95% CI (0.25, 2.60), respectively]. MIE could not significantly reduce the incidence of anastomotic leakage, recurrent laryngeal nerve palsy and chylothorax [OR 0.70, 95% CI (0.37, 1.32); OR 1.43, 95% CI (0.33, 6.25); HR = 1.79, 95% CI (0.67, 4.75), respectively], but the incidence of pneumonia was significantly reduced [HR = 0.43, 95% CI (0.22, 0.82)]. In addition, the length of hospital stay and the incidence of total complications were significantly reduced after MIE [MD = −2.61, 95% CI (− 3.10, − 2.12); HR = 0.66, 95% CI (0.45, 0.98), respectively].

Conclusion
MIE after neoadjuvant therapy is effective and safe. Compared with open esophagectomy, MIE can improve the long-term survival and reduce the incidence of postoperative complications of esophageal cancer patients.

Authors: Korça Edina , Veres Gábor , Szabó Gábor 
Published: March 2023

Abstract
Background
We discuss a rare case of an adult patient with different pathologies involving the aortic and pulmonary valves in need of surgery.

Case presentation
The patient had a history of congenital PV stenosis and surgical valvuloplasty. Almost 50 years later the patient underwent a complex second heart surgery due to infective endocarditis of the aortic valve and high-grade restenosis of the pulmonary valve. Replacement of the aortic and pulmonary valve, as well as reconstruction of the RVOT and closure of a persistent foramen ovale, followed. Postoperative course was uneventful and the patient was discharged home a week after surgery.

Conclusion
Simultaneous surgery of pulmonary and aortic valves due to different pathologies is rare but can be performed successfully even in advanced age and can improve quality of life.
Temporary tracheotomy for post-intubation laryngeal edema after lung cancer surgery: a case report
Authors: Iijima Yoshihito , Takaoka Yuki , Motono Nozomu , Uramoto Hidetaka 
Published: March 2023

Abstract
Background
In the post-intubation period, laryngeal edema is one of the most severe complications, which can cause significant morbidity and even death. Herein, we report a case in which we performed a temporary tracheostomy during surgery because of the risk of postoperative laryngeal edema, successfully avoiding post-intubation laryngeal edema complications.

Case presentation
A 78-year-old man underwent surgery for left upper lobe lung cancer. He had a history of chemoradiotherapy for laryngeal cancer, bronchial asthma, and chronic obstructive pulmonary disease. He was diagnosed with grade 1 laryngeal edema using computed tomography, and there was a risk of developing post-intubation laryngeal edema. Additionally, there was a decrease in laryngeal and pulmonary functions; therefore, postoperative aspiration pneumonia was judged to be a fatal risk. A temporary tracheostomy was performed during surgery to avoid postoperative intubation laryngeal edema. He was found to have exacerbated laryngeal edema, which is a serious complication of airway stenosis.

Conclusions
Temporary tracheostomy should be considered to avoid airway stenosis due to post-intubation laryngeal edema in patients with laryngeal edema after radiotherapy.

Abstract
Background
Mitochondrial dysfunction is considered to be an important contributor in podocyte injury under diabetic conditions. The BaoShenTongLuo (BSTL) formula has been shown to reduce podocyte damage and postpone the progression of diabetic kidney disease (DKD). The potential mechanisms underlying the effects of BSTL, however, have yet to be elucidated. In this study, we aimed to investigate whether the effects of BSTL are related to the regulation of mitochondrial biogenesis via the adenosine monophosphate-activated protein kinase (AMPK) pathway.

Methods
High-Performance Liquid Chromatography Electrospray Ionization Mass Spectrometer (HPLC–ESI–MS) analysis was performed to investigate the characteristics of pure compounds in BSTL. db/db mice and mouse podocyte clone-5 (MPC5) cells were exposed to high glucose (HG) to induce DKD and podocyte damage. Body weight, random blood glucose, urinary albumin/creatinine ratio (UACR), indicators of renal function and renal histological lesions were measured. Markers of podocyte injury, mitochondrial morphology, mitochondrial deoxyribonucleic acid (mtDNA) content, mitochondrial respiratory chain complexes activities, reactive oxygen species (ROS) production, and mitochondrial membrane potential (MMP) levels were assessed. Protein expressions of AMPK, peroxisome proliferator-activated receptor gamma coactivator 1 alpha (PGC-1α), transcription factor A (TFAM), mitochondrial fusion protein 2 (MFN2) and dynamin-related protein 1 (DRP1) were also detected. MPC5 cells were transfected with AMPKα small interfering RNA (AMPKα siRNA) to determine the underlying mechanisms of BSTL improvement of mitochondrial function under diabetic conditions.

Results
In vivo, treatment with BSTL reduced the UACR levels, reversed the histopathological changes in renal tissues, and alleviated the podocyte injury observed in db/db mice. After BSTL treatment, the decreased mtDNA content and mitochondrial respiratory chain complex I, III, and IV activities were significantly improved, and these effects were accompanied by maintenance of the protein expression of p-AMPKαT172, PGC-1α, TFAM and MFN2. The in vitro experiments also showed that BSTL reduced podocyte apoptosis, suppressed excessive cellular ROS production, and reversed the decreased in MMP that were observed under HG conditions. More importantly, the effects of BSTL in enhancing mitochondrial biogenesis and reducing podocyte apoptosis were inhibited in AMPKα siRNA-treated podocytes.

Conclusion
BSTL plays a crucial role in protecting against podocyte injury by regulating the AMPK-mediated mitochondrial biogenesis in DKD.

Published: March 2023

Abstract
Background
In Ethiopia, highland bamboo has been cultivated in various niches: farmlands, riverbanks, woodlot boundaries, and homesteads, and agroforestry systems. However, the biomass and carbon storage of potential of bamboo forests across niches is not well characterized in Ethiopia. Therefore, this study was conducted to estimate the biomass and carbon storage potential of highland bamboo plantations in northwestern Ethiopia. To this end, a total of 60 circular plots measuring 100 m2 with a radius of 5.64 m were randomly established on the homestead, woodlot, and riverbank plantation niches to conduct the inventory. The biomass storage of bamboo was calculated based on previously published allometric equations. Biomass and carbon stock variations among age-classes and niches of bamboo forests were analyzed using analysis of variance (ANOVA) and subsequent pairwise means comparisons of carbon stocks among niches were performed via post hoc Tukey test at p < 0.05.

Results
Results showed that the mean aboveground biomass (AGB) ranged from 150.18 – 191.42 Mg ha−1 in the entire niches. The highest amount of AGB was stored in the homestead niche (191.42 Mg ha−1) followed by the woodlot (180.11 Mg ha−1) and riverbank niche (150.17 Mg ha−1), respectively. The highest carbon stock (111.56 Mg C ha−1) was found in the homestead niche while the smallest amount was recorded in the riverbank niche (87.52 Mg ha−1). The homestead bamboo plantation has the highest biomass storage due to the application of manure and natural fertilizer, regular harvesting and management of culms, and protection from illegal harvesting and grazing.

Conclusion
This study highlights the importance of bamboo plantations in climate change mitigation. Hence, bamboo plantation should be promoted; and natural resource management and forestry departments of the government, Universities, research centers, the International Bamboo and Rattan Organization (INBAR), and other partners should work with local communities to expand bamboo plantation on their homesteads and degraded lands.

Abstract
Background
GLUT1 deficiency syndrome is a rare, genetically determined neurological disorder for which Ketogenic Dietary Treatment represents the gold standard and lifelong treatment. Patient registries are powerful tools providing insights and real-world data on rare diseases.

Objective
To describe the implementation of a national web-based registry for GLUT1-DS.

Methods
This is a retrospective and prospective, multicenter, observational registry developed in collaboration with the Italian GLUT1-DS association and based on an innovative, flexible and configurable cloud computing technology platform, structured according to the most rigorous requirements for the management of patient’s sensitive data. The Glut1 Registry collects baseline and follow-up data on the patient’s demographics, history, symptoms, genotype, clinical, and instrumental evaluations and therapies.

Results
Five Centers in Italy joined the registry, and two more Centers are currently joining. In the first two years of running, data from 67 patients (40 females and 27 males) have been collected. Age at symptom onset was within the first year of life in most (40, 60%) patients. The diagnosis was formulated in infancy in almost half of the cases (34, 51%). Symptoms at onset were mainly paroxysmal (mostly epileptic seizure and paroxysmal ocular movement disorder) or mixed paroxysmal and fixed symptoms (mostly psychomotor delay). Most patients (53, 79%) are currently under Ketogenic dietary treatments.

Conclusions
We describe the principles behind the design, development, and deployment of the web-based nationwide GLUT1-DS registry. It represents a stepping stone towards a more comprehensive understanding of the disease from onset to adulthood. It also represents a virtuous model from a technical, legal, and organizational point of view, thus representing a possible paradigmatic example for other rare disease registry implementation.
The era of cryptic exons: implications for ALS-FTD

Published: March 2023

AbstractTDP-43 is an RNA-binding protein with a crucial nuclear role in splicing, and mislocalises from the nucleus to the cytoplasm in a range of neurodegenerative disorders. TDP-43 proteinopathy spans a spectrum of incurable, heterogeneous, and increasingly prevalent neurodegenerative diseases, including the amyotrophic lateral sclerosis and frontotemporal dementia disease spectrum and a significant fraction of Alzheimer’s disease. There are currently no directed disease-modifying therapies for TDP-43 proteinopathies, and no way to distinguish who is affected before death. It is now clear that TDP-43 proteinopathy leads to a number of molecular changes, including the de-repression and inclusion of cryptic exons. Importantly, some of these cryptic exons lead to the loss of crucial neuronal proteins and have been shown to be key pathogenic players in disease pathogenesis (e.g., STMN2), as well as being able to modify disease progression (e.g., UNC13A). Thus, these aberrant splicing events make promising novel therapeutic targets to restore functional gene expression. Moreover, presence of these cryptic exons is highly specific to patients and areas of the brain affected by TDP-43 proteinopathy, offering the potential to develop biomarkers for early detection and stratification of patients. In summary, the discovery of cryptic exons gives hope for novel diagnostics and therapeutics on the horizon for TDP-43 proteinopathies.
Surgical dose and the clinical outcome in the treatment of mammary gland tumours in female dogs: a literature review
Authors: Hörnfeldt Maria Bennet , Mortensen Jacob Kvesel 
Published: March 2023

AbstractMammary gland tumours are the most frequent tumours in intact female dogs and surgery remains the main treatment modality. Surgery is traditionally performed according to the lymphatic drainage of the mammary glands, but robust evidence is still lacking on what surgical dose is the smallest and results in the best outcome. The objective of the study was to investigate whether choice of surgical dose influences treatment outcome in dogs with mammary tumours and to identify current gaps in research that need to be filled in future studies for identifying the smallest surgical dose with the best possible outcome. Articles for entrance into the study were identified in online databases. Information regarding outcome following use of different surgical doses was extracted for analysis. Also, known prognostic factors were mapped for each study to discuss their impact on treatment outcome. Twelve articles were identified and included. Surgical dose applied ranged from lumpectomy to radical mastectomy. Radical mastectomy was most often analysed [11/12 (92%) articles]. Less invasive surgical doses were used less often in decreasing order of invasiveness. Outcomes analysed were most often survival time [7/12 (58%) articles], frequency of recurrences [5/12 (50%) studies] and time to recurrence [5/12 (42%) studies)]. No studies demonstrated any significant association between surgical dose and outcome. Gaps in the research could be categorised as data that was not available for extraction, for example known prognostic factors. Other factors related to study design were also identified, for example small groups of dogs included into the study. No studies showed a clear benefit of choosing one surgical dose over the other. Choice of surgical dose should be based on known prognostic factors and risks for complications rather than on lymphatic drainage. In future studies all prognostic factors should be included when investigating how choice of surgical dose influences treatment outcome.

Published: March 2023

Abstract
Background
Zoonotic livestock-associated methicillin-resistant Staphylococcus aureus (LA-MRSA) is widely spread in pig herds in many countries. However, the knowledge regarding the survival of LA-MRSA in the pig farm environment is currently limited. The aim of this study was to assess the survival of LA-MRSA on different surface materials found in the farm environment. The study investigated the survival of two different LA-MRSA strains belonging to the clonal complex (CC) 398 on four different surfaces: stainless steel, polypropylene plastic, K30 concrete and commercial concrete disk coupons. The survival of the bacteria over time was determined by the viable count method and, where possible, fitting a model to the observed data by using nonlinear least squares method to calculate the half-life ($${t}_{1/2}$$

) for different strain and material combinations.

Results
The study showed that the half-life of the bacteria was longer on polypropylene plastic ($${t}_{1/2}$$

=2.45–7.83 days). On these materials, both LA-MRSA strains survived through the 14 week observation period. The bacterial decay was fastest on the concrete surfaces, where LA-MRSA became undetectable after 3–9 weeks.

Conclusions
The survival of LA-MRSA in the pig farm environment may be affected by different surface materials. A more frequent sampling protocol (< 7 days) is needed to determine the half-life on concrete surfaces.

Abstract
Background
Armed conflicts greatly affect the health, nutrition, and food security of conflict affected settings particularly children. However, no empirical data exist regarding context specific factors contributing towards acute malnutrition in the war-torn Tigray, Ethiopia. Thus, this study aimed to identify individual and community level factors associated with acute malnutrition among children aged 6–59 months from armed conflict affected settings of Tigray, Ethiopia.

Methods
A community based cross-sectional study was conducted among 3,614 children aged 6–59 months in Tigray, from July 15 to Aug 15, 2021. Study participants were selected using a two-stage random sampling method. A structured questionnaire was used to collect data by interviewing mothers/caregivers. Mid upper arm circumference (MUAC) measurements were taken from upper left arm of the children using MUAC tapes. Multivariable multilevel logistic regression analysis was used to determine factors associated with acute malnutrition. Adjusted Odds ratio (AOR) with 95% CI were estimated to describe the strength of associations at p < 0.05.

Results
More than half (52.5%) of the sampled children were males in sex. Immediately after the first nine months into the conflict, the prevalence of severe, moderate, and global acute malnutrition was very high (5.1%, 21.8%, and 26.9%, respectively) in Tigray. The lowest and highest burden of child acute malnutrition was reported from Mekelle zone (13.3%) and Southeastern zone (36.7%), respectively. Individual-level factors such as older child age (AOR = 0.13, 95% CI: 0.10, 0.18), female child sex (AOR = 1.24, 95% CI 1.05, 1.480.95), Vitamin-A supplementation (AOR = 1.3, 95% CI: 1.05, 1.65), and history of diarrhea (AOR = 1.22, 95%CI: 1.02, 1.53) and community-level factors like unimproved drinking water source (AOR = 1.31, 95%CI: 1.08, 1.58), unimproved toilet facility (AOR = 1.24, 95% CI: 1.01, 1.52), and severe food insecurity (AOR = 1.55, 95% CI: 1.16. 2.07) were significantly associated with childhood acute malnutrition.

Conclusions
The burden of acute malnutrition is a severe public health problem in Tigray. To prevent the untimely suffering and death of children, regular nutrition screening, speedy, and appropriate referral of all malnourished children to nutritional services and large-scale humanitarian assistance including access to food; nutrition supplies; water, sanitation and hygiene supplies; and health care in a timely manner are required. In the prevailing armed conflict, these have been very difficult to achieve. Thus, immediate international intervention is needed.

Abstract
Background
Traction tables have long been utilized in the management of fractures by orthopaedic surgeons. The purpose of this study was to systematically review the literature to determine the complications inherent to the use of a perineal post when treating femur fractures using a traction table.

Methods
A systematic review was conducted using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) using PubMed, EMBASE, and Cochrane Library. The search phrase used was “fracture” AND “perineal” AND “post” AND (“femur” OR “femoral” OR “intertrochanteric” OR “subtrochanteric”). Inclusion criteria for this review were: level of evidence (LOE) of I – IV, studies reporting on patients surgically treated for femur fractures, studies reporting on patients treated on a fracture table with a perineal post, and studies that reported the presence or absence of perineal post-related complications. The rate and duration of pudendal nerve palsy were analyzed.

Results
Ten studies (2 prospective and 8 retrospective studies; 2 LOE III and 8 LOE IV) were included consisting of 351 patients of which 293 (83.5%) were femoral shaft fractures and 58 (16.5%) were hip fractures. Complications associated with pudendal nerve palsies were reported in 8 studies and the mean duration of symptoms ranged between 10 and 639 days. Three studies reported a total of 11 patients (3.0%) with perineal soft tissue injury including 8 patients with scrotal necrosis and 3 patients with vulvar necrosis. All patients that developed perineal skin necrosis healed through secondary intention. No permanent complications relating to pudendal neurapraxia or soft tissue injuries were reported at final follow-up timepoints.

Conclusion
The use of a perineal post when treating femur fractures on a fracture table poses risks for pudendal neurapraxia and perineal soft tissue injury. Post padding is mandatory and supplemental padding may also be required. Appropriate perineal skin examination prior to use is also important. Occurring at a higher rate than previously thought, appropriate post-operative examination for any genitoperineal soft tissue complications and sensory disturbances should not be ignored.
