xlomafota13 shared this article with you from Inoreader

In Vivo. 2022 Jan-Feb;36(1):375-380. doi: 10.21873/invivo.12713.

ABSTRACT

BACKGROUND/AIM: The effect of sarcopenia on patients with severe Covid-19 disease is unknown. We aimed to assess the influence of baseline computed tomography (CT)-based body composition parameters (pectoralis muscle area, pectoralis muscle index, skeletal muscle gauge) on clinical variables in patients with severe Covid-19 disease.

PATIENTS AND METHODS: Chest CT scans of adult patients with confirmed Covid-19 who were hospitalized from March 2020 to May 2021 at a level-one medical center in Germany were retrospectively analyzed. Pectoralis muscle area, pectoralis muscle index and skeletal muscle gauge were measured on the first CT scan after admission. Body composition parameters were assessed for association with clinical variables and 30-day mortality.

RESULTS: A total of 46 patients were included. None of the body composition parameters was a pred ictor for 30-day mortality, duration of hospital stay, duration of intensive care unit treatment, or duration of invasive mechanical ventilation.

CONCLUSION: Pectoralis muscle composition parameters in CT chest scans did not predict outcomes in adult patients with severe Covid-19 infection.

xlomafota13 shared this article with you from Inoreader

In Vivo. 2022 Jan-Feb;36(1):409-415. doi: 10.21873/invivo.12718.

ABSTRACT

BACKGROUND/AIM: To investigate changes in post-progression chemotherapy (PPC) before and after nivolumab approval and determine their prognostic impact.

PATIENTS AND METHODS: A total of 146 patients with unresectable gastric cancer who had at least progressive disease after first- and/or second-line chemotherapy were retrospectively enrolled.

RESULTS: Among the 146 patients, 46 and 23 received ramucirumab and nivolumab, respectively. Moreover, 95 and 62 patients received PPC after first- and second-line chemotherapy, respectively. Group B (i.e., at least chemotherapy after nivolumab approval) had significantly higher proportions of patients receiving ramucirumab therapy, nivolumab therapy, and PPC after first- or second-line chemotherapy compared to group A (i.e., termination of chemotherapy before nivolumab approval). Group A had significantly poorer prognosis than group B. Multivariate analysis showed that age, number of distant metastatic sites, and ramucirumab therapy were independent prognostic factors.

CONCLUSION: Changes in chemotherapeutic strategies, including PPC, might contribute to improved prognosis in patients with advanced gastric cancer.

xlomafota13 shared this article with you from Inoreader

In Vivo. 2022 Jan-Feb;36(1):439-445. doi: 10.21873/invivo.12722.

ABSTRACT

BACKGROUND/AIM: This study aimed to determine the effectiveness of surgical site infection (SSI) prevention approaches in rectal cancer surgery.

PATIENTS AND METHODS: A total of 1,408 patients who underwent elective rectal cancer surgery between 1995 and 2017 were reviewed. Patients were divided into three groups: control group (group A, n=245), SSI prevention intervention group (group B, n=516), and laparoscopic or robotic surgery group (group C, n=647). The groups were compared in terms of SSI and anastomotic leakage (AL) incidences, and risk factors for SSI were investigated.

RESULTS: The overall SSI and AL rates were 19.4% and 3.6%, respectively. These rates were significantly lower in Group C (9.3%, 1.7%), compared to Groups A (40.0%, 6.1%) and B (22.5%, 3.5%). Abdominoperineal resection, open surgery, operation time, intraoperative bleeding, lac k of absorbable sutures, lack of mechanical bowel preparation, and lack of oral antibiotics were independently associated with SSI.

CONCLUSION: SSI reduction after rectal cancer surgery was achieved through various intervention strategies.

Predicting Overall Survival Using Preoperative Nutritional and Inflammation Status for Colorectal Cancer

xlomafota13 shared this article with you from Inoreader

In Vivo. 2022 Jan-Feb;36(1):450-457. doi: 10.21873/invivo.12724.

ABSTRACT

AIM: It has been shown that nutritional status and inflammation correlate with survival in patients with various cancer types. In this study, we evaluated several kinds of nutritional and inflammation parameters in preoperative blood samples and constructed new risk model predicting survival in patients with colorectal cancer.

PATIENTS AND METHODS: We retrospectively examined 286 patients with stage I-III colorectal cancer who had undergone curative resection at Teikyo University Hospital. The association between overall survival (OS) and nutritional status and inflammation factors were examined using Kaplan-Meier curves and log-rank tests.

RESULTS: Serum albumin, cholesterol and C-reactive protein concentration, neutrophil count and platelet count were shown to be correlated with OS. We constructed a new risk model (nutrition inflammation status, NIS ) using these factors, and compared it with other nutrition and inflammation models.

CONCLUSION: NIS was useful as a new model for predicting OS in patients undergoing curative resection for colorectal cancer, compared with known models.

Synchronous Basal Cell Carcinoma and Squamous Cell Carcinoma of Nasal Vestibule With Novel Unique Variants Identified by Whole-exome Sequencing

xlomafota13 shared this article with you from Inoreader

In Vivo. 2022 Jan-Feb;36(1):251-257. doi: 10.21873/invivo.12698.

ABSTRACT

BACKGROUND/AIM: It is estimated that nonmelanoma skin cancer (NMSC), including basal cell carcinoma (BCC) and squamous cell carcinoma (SCC), affects more than 3 million Americans each year. Translation of next-generation sequencing (NGS) data into identification of new potential targets for therapeutic applications may be helpful. Whole-exome sequencing (WES) is a widely used NGS method that involves sequencing the protein-coding regions of the genome.

CASE REPORT: We report a case of a 65-year-old female smoker who was found to have two 6 mm lesions in her left nasal vestibule. Biopsies demonstrated synchronous BCC and SCC. The patient underwent surgical excision of both cancers with safe margins followed by plastic reconstruction. WES was performed on both cancers and 16 alterations including BRCA2 (p.P389S), FAM5C (S420L), KMT2A (P855L), and SMO (L412F), as unique for BCC, and 4 alterations including TP53 (p.H179Q) and CDKN2A (p.P114L), as unique for SCC, were identified.

CONCLUSION: We report the first documented case with unique genetic alterations in two distinct and synchronous skin BCC and SCC arising from the same nasal vestibule of a patient. This adds to the growing field of data regarding genetic variants in characterizing malignancies and potentially for targeted therapies.

Vesico-uterine Fistula Following C-section - A Case Report and Literature Review

xlomafota13 shared this article with you from Inoreader

In Vivo. 2022 Jan-Feb;36(1):528-532. doi: 10.21873/invivo.12734.

ABSTRACT

BACKGROUND/AIM: Vesico-uterine fistulas represent a rare type of genito-urinary fistulas; however, due to the increasing incidence of Caesarean section (C-section) in the last decade, this abnormal communication between the urinary and genital tracts has been reported more often after such surgical procedures. The aim of the current article was to report the case of a 28-year-old patient who was submitted to surgery for a vesico-uterine fistula seven years after a C-section.

CASE REPORT: The 28-year-old patient with a previous history of four vaginal deliveries and one C-section was self-presented to the Gynecology Department for cyclic hematuria and diagnosed with a vesico-uterine fistula after injecting methylene blue in the uterine cavity during hysteroscopy. The patient was further submitted to surgery, and a parcelar myometrectomy en bloc with parcelar cystectomy, cystography, and prophylactic salpingectomy was performed. The postoperative outcome was uneventful.

CONCLUSION: Although vesico-uterine fistulas represent rare events, they should be considered, especially in young patients with a previous history of C-section.

Sternocleidomastoid Muscle Transfer for Treatment of Longstanding Facial Paralysis: Long-term Outcomes and Complications

xlomafota13 shared this article with you from Inoreader

In Vivo. 2022 Jan-Feb;36(1):501-509. doi: 10.21873/invivo.12731.

ABSTRACT

BACKGROUND/AIM: The use of sternocleidomastoid muscle (SCM) flap for facial reanimation was established in the 1980s by the senior author of this paper. We aimed to analyze long-term outcome and complications of this procedure.

PATIENTS AND METHODS: We conducted a retrospective chart review of all patients undergoing SCM reanimation for longstanding facial palsy between January 2009 and December 2015. Patients with follow-up longer than 12 months (range=12-96) were included in the study. Facial muscle function was evaluated before and at each follow-up after the surgery with the House-Brackmann (HB) scale-facial nerve grading system and Facegram analysis. Donor site morbidity and overall complication rates were documented and analyzed.

RESULTS: Forty-two patients aged 18-66 years (mean age=37) with a mean duration of facial palsy of 5 years (range=2-4 8) met the inclusion criteria. The HB score 2 years after surgery improved significantly (p<0.05) in comparison to the pre-operative condition (3.6 vs. 4.7). Twelve months after surgery, oral commissure excursion improved by mean 8.95 mm. No flap necrosis occurred, nor compromise of neck and shoulder function despite an obvious contour defect in the SCM donor site. None of the patients presented head posture or movement issues.

CONCLUSION: The SCM flap transfer is a reliable and effective procedure to achieve moderate improvement of the oral commissure excursion using a local method with moderate donor site morbidity. It can be regarded as a valuable option for dynamic facial reanimation in case of longstanding facial palsy.

Colonic Metastasis from Breast Cancer: A Case Report and Review of the Literature

xlomafota13 shared this article with you from Inoreader

In Vivo. 2022 Jan-Feb;36(1):522-527. doi: 10.21873/invivo.12733.

ABSTRACT

BACKGROUND: Breast cancer often metastasizes to the lungs, bones, liver, and brain, colon metastasis from breast cancer (CMBC) is extremely rare.

CASE REPORT: The patient was a 63-year-old female. Mastectomy had been performed for breast cancer (pStage IIB) 15 years earlier at another hospital. Metastasis to the lumbar spine had been detected 4 years prior to referral to us and the patient had undergone hormonal therapy with an aromatase inhibitor. Furthermore, early primary sigmoid colon cancer had been endoscopically resected 2 years before referral. The patient was diagnosed with cancer recurrence in the colon at follow-up examinations performed 2 years after that endoscopic resection. After referral to our hospital, laparoscopic sigmoidectomy was performed. Based on the histopathological examination and immunohistological staining results (positive for cytokeratin 7, GATA-binding protein 3, estrogen receptor and human epidermal growth factor receptor-related 2 (2+); negative for cytokeratin 20, progesterone receptor, E-cadherin, gross cystic disease fluid protein 15 and caudal-related homeobox 2) the final pathological diagnosis was CMBC.

CONCLUSION: Although extremely rare, the possibility of CMBC should be considered in the case of colonic tumors in patients with a history of breast cancer.

Establishment and Characterization of FusionRed Stable Transfected Canine Prostate Adenocarcinoma and Transitional Cell Carcinoma Cells

xlomafota13 shared this article with you from Inoreader

In Vivo. 2022 Jan-Feb;36(1):170-179. doi: 10.21873/invivo.12688.

ABSTRACT

BACKGROUND/AIM: Cancer cell inoculation is routinely used to evaluate novel therapeutic approaches in vivo. However, without reporter genes enabling deep tissue imaging, study of early tumor progression and therapeutic responses is often limited. We describe the establishment and characterization of two canine cancer cell lines stably expressing red fluorescence proteins as tools for later in vivo imaging.

MATERIALS AND METHODS: Two red fluorescence cell lines were generated by plasmid transfection. Fluorescence protein expression was confirmed by flow cytometry and microscopy. Deep tissue imaging was demonstrated in mice using a NightOWL LB 983. Gene expression changes after transfection were analyzed by RNAseq.

RESULTS: Both cell lines were detectable in vivo by subcutaneous injection of 1×106 cells. RNAseq revealed up to 2005 transfection-induced differentially expressed genes but no significant changes in cellular key pathways.

CONCLUSION: The fluorescent cell lines provide a solid basis for future in vivo studies on canine cancer.

Framework for Indirect Spatial Calibration of the Horizontal Plane of Endoscopic Laryngeal Images

xlomafota13 shared this article with you from Inoreader
Calibrated horizontal-plane measurements from laryngeal images could contribute significantly to refining evidence-based practice and developing patient-specific models and precision-medicine approaches. Laser-projection endoscopes can address the need for direct calibrated measures; however, these systems are not widely available. This study presents the framework for an alternative indirect horizontal-plane calibration approach.
