In Vivo. 2021 Mar-Apr;35(2):965-968. doi: 10.21873/invivo.12338.

ABSTRACT

BACKGROUND/AIM: Adult outpatients with symptomatic COVID-19 treated with fluvoxamine, compared with placebo, had a lower likelihood of clinical deterioration over 15 days. Fluvoxamine strongly binds to the sigma-1 receptor (S1R) that regulates inflammation by inhibiting the production of cytokines, believed to be responsible for severe COVID-19. We evaluated the S1R locus on chr 9p13.3 in subjects tested positive for SARS-CoV-2. We focused on SNP rs17775810 that has been previously identified by examining loss-of-function mutations in the S1R gene associated with distal hereditary motor neuropathy.

PATIENTS AND METHODS: We utilized UK Biobank (UKB) data. Data processing was performed on Minerva, a Linux mainframe with Centos 7.6, at the Icahn School of Medicine at Mount Sinai.

RESULTS: The effect of rs17775810 genotype on survival was significant (p=0 .036, 2 tailed Fisher exact test). The minor allele homozygotes (TT) had the lowest death rate (0%), whereas the non-TT genotypes (i.e. CT and CC) had the highest death rate (16.2%).

CONCLUSION: The rs17775810 analysis corroborates the favorable effect of fluvoxamine on COVID-19 survival.

xlomafota13 shared this article with you from Inoreader

In Vivo. 2021 Mar-Apr;35(2):1147-1150. doi: 10.21873/invivo.12361.

ABSTRACT

BACKGROUND/AIM: Extravasation associated with chemotherapy can induce localised injury, necrosis, and nerve damage, resulting in discontinued chemotherapy and impaired quality of life; however, risk factors for extravasation remain unclear. The present study aimed to identify chemotherapy regimen-associated factors related to extravasation.

PATIENTS AND METHODS: Data on patient and chemotherapy protocol characteristics were extracted from our hospital's electronic database; the frequency of extravasation was compared among patients receiving different chemotherapy regimens.

RESULTS: Twenty-two patients with extravasation undergoing chemotherapy during the study period were enrolled in the present study. Patients undergoing treatment with 5-fluorouracil and cisplatin were most likely to develop extravasation in the present study. All patients present ing with extravasation during treatment with 5-fluorouracil and cisplatin developed swelling and many (40%) developed erythema within the first two cycles of treatment.

CONCLUSION: Treatment with 5-fluorouracil combined with cisplatin increases the incidence of extravasation. Ensuring suitable vascular access and increasing awareness regarding the symptoms and timing of extravasation among patients and medical staff can improve extravasation prevention and diagnosis.

xlomafota13 shared this article with you from Inoreader

In Vivo. 2021 Mar-Apr;35(2):977-985. doi: 10.21873/invivo.12340.

ABSTRACT

BACKGROUND/AIM: Neoadjuvant chemotherapy without radiation (NAC) shows favorable outcomes for locally advanced rectal cancer (LARC), however, the optimal regimen has not been determined yet. This study aimed to compare the efficacy and safety of oxaliplatin, irinotecan, folinic acid, and 5-fluorouracil (mFOLFOXIRI) with capecitabine/S-1 and oxaliplatin (XELOX/SOX) in rectal cancer patients.

PATIENTS AND METHODS: We retrospectively examined patients with LARC who received mFOLFOXIRI or XELOX/SOX as NAC.

RESULTS: Between January 2015 and July 2019, 49 patients received mFOLFOXIRI and 37 patients received XELOX/SOX. The pathological response rates (over two-thirds affected tumor area) were 36.7% and 40.5% in the mFOLFOXIRI and XELOX/SOX groups, respectively. Grade 3/4 neutropenia was experienced by 45.0% of the patients in the mFOLFOXIRI group and 8.0% i n the XEOX/SOX group.

CONCLUSION: Although pathological responses were comparable between two groups, mFOLFOXIRI tended to be more toxic compared to XELOX/SOX as NAC for LARC.

Intra-abdominal Desmoid-Type Fibromatosis Mimicking Diverticulitis With Abscess: A Case Report

xlomafota13 shared this article with you from Inoreader

In Vivo. 2021 Mar-Apr;35(2):1151-1155. doi: 10.21873/invivo.12362.

ABSTRACT

BACKGROUND: Intra-abdominal desmoid-type fibromatosis (DF) rarely necessitates emergency surgery. However, the condition is difficult to diagnose preoperatively and can become life-threatening if left untreated.

CASE REPORT: A 46-year-old man complained of fever and right lower quadrant pain. In computed tomography, the mesenteric side of the ascending colon demonstrated air and fluid collections, suggesting diverticulitis with abscess. After 2 weeks of conservative treatment with fasting, the patient started to consume food; nonetheless, fever returned. Colonoscopy and contrast enema detected a fistula extending from the ascending colon to the abscess, with no surrounding lesions. Surgery was then performed because the abscess was refractory. During laparotomy, the scar tissue of the abscess was found to be attached to the lateral wall of the ascending c olon. Hence, right colectomy combined with abscess resection was performed. Histopathological findings revealed DF in the mesentery.

CONCLUSION: Although rare, DF should be included in the preoperative differential diagnosis of intra-abdominal abscesses.

Assessment of Pain, Acceptance of Illness, Adaptation to Life, and Strategies of Coping With the Disease, in Patients With Bladder Cancer

xlomafota13 shared this article with you from Inoreader

In Vivo. 2021 Mar-Apr;35(2):1157-1161. doi: 10.21873/invivo.12363.

ABSTRACT

BACKGROUND/AIM: Bladder cancer is one of the most common cancers and causes of mortality in Poland, significantly reducing the quality of life. The objective of the study was to evaluate the strategy of coping with the disease in patients suffering from bladder cancer.

PATIENTS AND METHODS: Four psychometric tests were used: the beliefs about pain control questionnaire (BPCQ), the pain coping strategies questionnaire (CSQ), acceptance of illness scale (AIS), and mental adjustment to cancer (Mini-Mac) test.

RESULTS: Patients suffering from bladder cancer assign the greatest role in controlling pain to the influence of physicians. The most frequently chosen strategy for coping with the disease was declaring coping. The average level of acceptance of the disease among patients was mean=27.25. The most often indicated manner of coping was fighting spiri t.

CONCLUSION: Patients with bladder cancer are characterized by a constructive attitude towards the disease.

xlomafota13 shared this article with you from Inoreader

In Vivo. 2021 Mar-Apr;35(2):1007-1015. doi: 10.21873/invivo.12344.

ABSTRACT

BACKGROUND/AIM: Breast cancer survivors are increasingly interested in lifestyle modifications in order to reduce the risk of recurrence and mortality. Therefore, we aimed to study the association between survival and lifestyle related risk factors such as obesity, alcohol intake, smoking, medication and atopic diseases.

PATIENTS AND METHODS: In this observational single center study, clinicopathological parameters of 635 women with primary breast cancer were sampled. A logistic regression model was applied to investigate correlations among clinical data and various life style related factors. Patients were stratified according to lifestyle and treatment characteristics. Cox regression and the Kaplan-Meier method were used to analyze survival differences in various patient subsets and to identify possible prognostic factors.

RESULTS: Logistic regres sion analysis indicated a correlation between low Body Mass Index (BMI) and extended progression-free survival (PFS). Cox regression showed that patients not using beta-blockers had a significantly prolonged overall survival (OS) compared to beta-blocker users [hazard ratio (HR)=3.7; 95% confidence interval (CI)=1.66-8.14, p=0.01]. Apparently, the clincopathological parameters including BMI, HER2-, estrogen receptor (ER) and progesteron receptor (PR)-status as well as treatment with chemo-, radio- and endocrine therapy did not play a role regarding the survival differences between beta-blocker users and non-users.

CONCLUSION: Patients not using beta-blockers appeared to benefit from extended PFS and OS. Further, patients with a rather low BMI (<30 kg/m2) seemed to have a survival benefit compared to obese patients. Particularly, among postmenopausal women, beta-blocker intake and obesity appeared to be possible life style related prognostic factors that could be used for patient stratification.

xlomafota13 shared this article with you from Inoreader

In Vivo. 2021 Mar-Apr;35(2):1163-1168. doi: 10.21873/invivo.12364.

ABSTRACT

BACKGROUND/AIM: This study aimed to assess the association of the modified albumin-bilirubin (mALBI) grade with the endoscopic findings of gastroesophageal varices (GEVs).

PATIENTS AND METHODS: A total of 141 patients with histologically proven cirrhosis who underwent a liver biopsy and esophagogastroduodenoscopy were enrolled. The relationships between the mALBI grade and endoscopic findings were evaluated.

RESULTS: The incidence of GEVs and high-risk GEVs differed among mALBI grades. Patients with mALBI grades of 2b-3 had higher rates of GEVs and high-risk GEVs in comparison to those with mALBI grades of 1-2a (p<0.0001). In addition, patients with mALBI grade 2b or grade 3, but not those with mALBI grade 2a, had significantly higher rates of complicated GEVs and high-risk GEVs in comparison to those with mALBI grade 1.

CONCLUSION: The mAL BI grade may be useful in predicting the presence of GEVs and for stratifying their bleeding risk.

Implications of Preoperative Transbronchial Lung Biopsy for Non-small Cell Lung Cancer Less than 3-cm

xlomafota13 shared this article with you from Inoreader

In Vivo. 2021 Mar-Apr;35(2):1027-1031. doi: 10.21873/invivo.12346.

ABSTRACT

BACKGROUND/AIM: Transbronchial lung biopsy (TBLB) has been recommended for patients with suspected lung cancer. However, its diagnostic value is limited to small lesions, and some studies have indicated that biopsy might be related to metastasis and/or dissemination. This study aimed to evaluate the outcomes after preoperative TBLB for non-small cell lung cancer (NSCLC) patients.

PATIENTS AND METHODS: Data were reviewed from 371 patients with resected pN0 NSCLC less than 3-cm. Patients were divided into two groups: TBLB and Non-TBLB. Recurrence-free survival (RFS) curves were plotted using the Kaplan-Meier method. Cox regression analyses were used to evaluate the hazard ratio (HR) with the endpoint RFS.

RESULTS: The 5-year RFS rates were 75.5% in the TBLB group and 91.4% in the Non-TBLB group (p<0.001). Poor RFS was independently associated with TBLB (HR=2.491, 95%CI=1.337-4.640; p=0.004).

CONCLUSION: Preoperative TBLB may adversely affect RFS among NSCLC patients with small size tumours.

xlomafota13 shared this article with you from Inoreader

In Vivo. 2021 Mar-Apr;35(2):1169-1176. doi: 10.21873/invivo.12365.

ABSTRACT

BACKGROUND/AIM: This study aimed to evaluate the outcome of radiation therapy for patients with distant lymph node (LN) metastases, without organ metastases from uterine cervical cancer (UCC).

PATIENTS AND METHODS: Twenty-six patients with UCC with distant LN metastases received radiotherapy and were retrospectively analyzed. The sites of distant LN metastasis were as follows; Supraclavicular in 19, inguinal in nine, axillary in four, and others in three. The mean dose prescribed for these was 50 (range=40-60) Gy.

RESULTS: The 2-year overall, cause-specific, and progression-free survival, and local control of primary tumor rates were 51.3%, 51.3%, 46.9%, and 67.9%. In multivariate analysis, performance status ≥1 (p=0.007), para-aortic LN metastases (p=0.001), and lack of high-dose-rate intracavitary brachytherapy (p=0.033) were significantly assoc iated with poor overall survival. Performance status ≥1 (p=0.004), and para-aortic LN metastases (p=0.014) were significantly associated with poor cause-specific survival.

CONCLUSION: This study demonstrated favorable local control in patients with UCC with distant LN metastases.

Neo-Bioscore in Guiding Post-surgical Therapy in Patients With Triple-negative Breast Cancer Who Received Neoadjuvant Chemotherapy

xlomafota13 shared this article with you from Inoreader

In Vivo. 2021 Mar-Apr;35(2):1041-1049. doi: 10.21873/invivo.12348.

ABSTRACT

AIM: Patients with triple-negative breast cancer (TNBC) who have not achieved pathological complete response (pCR) after neoadjuvant chemotherapy (NAC) were considered for adjuvant capecitabine. This study was to explore the utility of the Neo-Bioscore in guiding post-surgical therapy in TNBC.

PATIENTS AND METHODS: The Neo-Bioscore was calculated for patients with non-metastatic primary breast cancer who received NAC at National Cancer Center Hospital East, Japan.

RESULTS: A total of 329 patients were evaluated. The Neo-Bioscore stratified prognosis after NAC better than clinical or pathological stage. The Neo-Bioscore performed well in the selection of patients with TNBC with excellent prognoses despite non-pCR; no death was observed in patients who had a Neo-Bioscore of 2, the lowest score in those with TNBC.

CONCLUSION: The Neo-Bioscore can improve the prognostic stratification of patients after NAC for breast cancer over clinical and pathological staging and may enable the identification of patients with non-pCR TNBC who can avoid additional adjuvant chemotherapy.

Crossed Cerebellar Diaschisis in Alzheimer's Disease Detected by Arterial Spin-labelling Perfusion MRI

xlomafota13 shared this article with you from Inoreader

In Vivo. 2021 Mar-Apr;35(2):1177-1183. doi: 10.21873/invivo.12366.

ABSTRACT

BACKGROUND: Crossed cerebellar diaschisis (CCD) is a phenomenon with depressed metabolism and hypoperfusion in the cerebellum. Using arterial spin-labelling perfusion weighted magnetic resonance imaging (ASL PWI), we investigated the frequency of CCD in patients with Alzheimer's disease (AD) and differences between patients with and without CCD.

PATIENTS AND METHODS: In patients with AD who underwent a standardized magnetic resonance imaging including ASL PWI cerebral blood flow was evaluated in the cerebellum, and brain segmentation/volumetry was performed using mdbrain (mediaire GmbH, Berlin, Germany) and FSL FIRST (Functional Magnetic Resonance Imaging of the Brain Software Library).

RESULTS: In total, 65 patients were included, and 22 (33.8%) patients were assessed as being CCD-positive. Patients with CCD had a significantly smaller whole brain volume (862.8±49.9 vs. 893.7±62.7 ml, p=0.049) as well as white matter volume (352.9±28.0 vs. 374.3±30.7, p=0.008) in comparison to patients without CCD.

CONCLUSION: It was possible to detect CCD by ASL PWI in approximately one-third of patients with AD and was associated with smaller whole brain and white matter volume.
