Gastric outlet obstruction in uncomplicated mesentero-axial gastric volvulus associated to hiatal hernia.

Gastric volvulus is a rare condition determined by the rotation of one part of stomach around another. Stomach can rotate around its longitudinal or short axis or both. The presentation can be acute, subacute and chronic due to twisting and untwisting andimaging should be performed in the acute phase. MDCT shows high accuracy in thediagnosis and definition of gastric volvulus being the preferred diagnostic test in emergency settings. Gastric volvulus may be associated or determined by pre-existing hiatal hernia and accurate analysis of CT signs may be evaluated on order to differentiate between a stomach in an abnormal position and a volvulus.At CT, a displaced antrum at the same level or cranial to the fundus and a transition point at the pylorus is diagnostic for mesenteroaxial volvulus. We present a case of a 70 years old woman with mesenteroaxial volvulus in hiatal hernia.

Left side jejunal diverticulitis: US and CT imaging findings.

Small bowel jejunoileal diverticulosis is an uncommon and usually asymptomatic condition. Complications may occur such as acute diverticulitis including infection or perforation, bleeding, small bowel obstruction and volvulus. Herein we report a case of a 76 years-old woman with acute left side abdominal pain and tenderness. A clinical suspected diagnosis of colonic diverticulitis was formulated. She underwent Ultrasound that revealed a collapsed small bowel loop with a large sac-like out-pouching lesion with mixed content (fluid and pockets of air) associated to hyperechogenicity of perilesional fat. Because of the atypical US findings, the patient underwent abdominopelvic CT that confirmed that the large sac-like out-pouching was a jejunal inflamed diverticulum. The patient underwent emergency surgery. Radiologist should be aware of imaging findings of jejunoileal diverticulitis in order to achieve a prompt diagnosis.

Understanding the influencing factors and mechanism of social compensation for Chinese older adults using social media in the context of smart home: a qualitative analysis.

As a new generation of necessary terminals for future homes, smart homes have become one of the essential mediums for smart aging at home. This paper aims to explore how older adults who age at home can overcome the digital divide of the new medium and achieve social participation in the home context to realize active aging. Based on the theory of social compensation, we select the smart-home smart screen, a representative new medium product in China, and carry out open coding, spindle coding, selective coding, and theoretical construction of the original interview data through the grounded theory research method. The results show that the main factors affecting the social compensation of older adults to smart home social media include user interface quality, interaction quality, content quality, and service quality, and these four factors are used as external variables to compensate older adults socially, thereby stimulating the emotional experience and perception changes at the cognitive level of older adults and then affecting the adoption and acceptance of smart home social media by older adults. This study refines the factors influencing the older adults' use of smart home social media from the perspective of social compensation. It explains the mechanism of acceptable behavior of older adults, bridging the gap in previous literature on the influencing factors and behavioral mechanisms of older adults of smart home social media. This paper provides a theoretical basis and guidance for the subsequent academic research and software development practice of social media under new technological devices to further help older adults in China achieve active and healthy aging.

Tas-102 for Refractory Metastatic Colorectal Cancer: A Multicenter Retrospective Cohort Study.

Trifluridine/tipiracil (TAS-102) is an oral chemotherapy approved for the treatment of metastatic colorectal cancer. The efficacy and tolerability of TAS-102 were shown in phase II-III clinical trials and in several real-life studies. The elderly and other special subgroups are underrepresented in published literature. We conducted a retrospective multicenter study to assess the effectiveness and safety of TAS-102 in consecutive patients with pretreated mCRC. In particular, we estimated the effectiveness and safety of TAS-102 in elderly patients (aged ≥70, ≥75 and ≥80 years) and in special subgroups, e.g., patients with concomitant heart disease. One hundred and sixty patients were enrolled. In particular, 71 patients (44%) were 70 years of age or older, 50 (31%) were 75 years of age or older, and 23 (14%) were 80 years of age or older. 19 patients (12%) had a concomitant chronic heart disease, three (2%) patients were HIV positive, and one (<1%) patient had a DPYD gene polymorphism. In 115 (72%) cases TAS-102 was administered as a third-line treatment. The median overall survival (OS) in the overall population was 8 months (95% confidence interval [CI], 6-9), while the median progression-free survival (PFS) was 3 months (95% CI, 3-4). No significant age-related reduction in effectiveness was observed in the subpopulations of elderly patients included. The toxicity profile was acceptable in both the whole and subgroups' population. Our study confirms the effectiveness and safety of TAS-102 in patients with pretreated mCRC, suggesting a similar risk-benefit profile in the elderly.

Role of tertiary cytoreductive surgery in recurrent epithelial ovarian cancer: Systematic review and meta-analysis.

OBJECTIVE: To evaluate the clinical utility of tertiary cytoreductive surgery (TCS) in recurrent ovarian cancer. METHODS: MEDLINE via PubMed, Embase (Elsevier), ClinicalTrials.gov, Scopus (Elsevier) and Web of Science for studies from inception to 4/09/2021. Studies reporting disease specific survival (DSS) and overall survival (OS) among women who underwent optimal cytoreductive surgery as compared to those who had a suboptimal cytoreductive surgery at time of TCS were abstracted. Study quality was assessed with the Quality In Prognosis Studies (QUIPS) tool. The data were extracted independently by multiple observers. Random-effects models were used to pool associations and to analyze the association between survival and surgical outcomes. RESULTS: 10 studies met all the criteria for inclusion in the systematic review. Patients with optimal tertiary cytoreductive surgery had better DSS (HR = 0.35; 95% CI, 0.19-0.64, P < 0.001), with low heterogeneity (I2 = 0%, P = 0.41) when compared to those with suboptimal tertiary cytoreductive surgery. Pooled results from these studies also demonstrated a better OS (HR = 0.34; 95% CI, 0.15-0.74, P < 0.007) with moderate heterogeneity (I2 = 59%, P = 0.09) when compared to patients with a suboptimal tertiary cytoreductive surgery. This remained significant in a series of sensitivity analyses. Due to the limited number of studies, we were unable to do further subgroup analyses looking at outcomes comparing tertiary cytoreductive surgery to chemotherapy. CONCLUSION: In this systematic review and meta-analysis of observational studies examining tertiary cytoreductive surgery for recurrent ovarian cancer, optimal tertiary cytoreductive surgery was associated with improved OS and DSS survival compared to suboptimal tertiary cytoreductive surgery.

Self-reported smell and taste recovery in coronavirus disease 2019 patients: a one-year prospective study.

PURPOSE: The aim of the present study was to estimate the 1 year prevalence and recovery rate of self-reported chemosensory dysfunction in a series of subjects with previous mild-to-moderate symptomatic COVID-19. METHODS: Prospective study based on the SNOT-22, item "sense of smell or taste" and additional outcomes. RESULTS: 268/315 patients (85.1%) completing the survey at baseline also completed the follow-up interview. The 12 months prevalence of self-reported COVID-19 associated chemosensory dysfunction was 21.3% (95% CI 16.5-26.7%). Of the 187 patients who complained of COVID-19 associated chemosensory dysfunction at baseline, 130 (69.5%; 95% CI 62.4-76.0%) reported complete resolution of smell or taste impairment, 41 (21.9%) reported a decrease in the severity, and 16 (8.6%) reported the symptom was unchanged or worse 1 year after onset. The risk of persistence was higher for patients reporting a baseline SNOT-22 score ≥ 4 (OR = 3.32; 95% CI 1.32-8.36) as well as for those requiring ≥ 22 days for a negative swab (OR = 2.18; 95% CI 1.12-4.27). CONCLUSION: A substantial proportion of patients with previous mild-to-moderate symptomatic COVID-19 characterized by new onset of chemosensory dysfunction still complained on altered sense of smell or taste 1 year after the onset.

COVID-19 in the tonsillectomised population.

OBJECTIVE: Interactions between SARS-CoV-2 and pharyngeal associated lymphoid tissue are thought to influence the manifestations of COVID-19. We aimed to determine whether a previous history of tonsillectomy, as a surrogate indicator of a dysfunctional pharyngeal associated lymphoid tissue, could predict the presentation and course of COVID-19. METHODS: Multicentric cross-sectional observational study involving seven hospitals in Northern and Central Italy. Data on the clinical course and signs and symptoms of the infection were collected from 779 adults who tested positive for SARS-CoV-2, and analysed in relation to previous tonsillectomy, together with demographic and anamnestic data. RESULTS: Patients with previous tonsillectomy showed a greater risk of fever, temperature higher than 39°C, chills and malaise. No significant differences in hospital admissions were found. CONCLUSIONS: A previous history of tonsillectomy, as a surrogate indicator of immunological dysfunction of the pharyngeal associated lymphoid tissue, could predict a more intense systemic manifestation of COVID-19. These results could provide a simple clinical marker to discriminate suspected carriers and to delineate more precise prognostic models.

Role of surgery in gynaecological sarcomas.

Gynaecological sarcomas account for 3-4% of all gynaecological malignancies and have a poorer prognosis compared to gynaecological carcinomas. Pivotal treatment for early-stage uterine sarcoma is represented by total hysterectomy. Whereas oophorectomy provides survival advantage in endometrial stromal sarcoma is still controversial. When the disease is confined to the uterus, systematic pelvic and para-aortic lymphadenectomy is not recommended. Removal of enlarged lymph-nodes is indicated in case of disseminated or recurrent disease, where debulking surgery is considered the standard of care. Fertility sparing surgery for uterine leiomyosarcoma is not supported by strong evidence, whilst available data on fertility sparing treatment for endometrial stromal sarcoma are more promising. For ovarian sarcomas, in the absence of specific data, it is reasonable to adapt recommendations existing for uterine sarcomas, also regarding the role of lymphadenectomy in both early and advanced stage disease. Specific recommendations on cervical sarcomas' surgery are lacking. Existing data on surgical approach vary from radical hysterectomy to fertility-preserving surgery in the form of trachelectomy or wide local excision, however no definite conclusions can be drafted on the recommended surgical approach. For vulval sarcomas, complete surgical excision with at least 2 cm of free margin is considered to be the primary treatment which is associated with good prognosis. The aim of this review is to provide highest quality evidence to guide gynaecologic oncologists throughout surgical management of gynaecological sarcomas.

Pazopanib and pancreatic toxicity: a case report.

BACKGROUND: Pazopanib is an oral multitargeted tyrosine-kinase inhibitor, used as a single agent to treat advanced renal cell carcinoma. Treatment with other tyrosine-kinase inhibitors is known to be associated with asymptomatic elevations of serum amylase and lipase levels. As regards the pazopanib, data are lacking in literature. CASE PRESENTATION: We report one case of pancreatic toxicity associated with pazopanib administration. Before starting treatment, patient had no risk factors for pancreatitis. The patient, an Italian 68 years old woman, started pazopanib at doses of 800 mg daily as first-line therapy for metastatic renal cell carcinoma. Six months after the start of treatment, blood tests showed for the first time a significant increase in serum lipase and amylase in the absence of symptoms and radiological findings of pancreatitis. The patient continued treatment without interruptions or dose reductions. However, the continuation of the treatment led to a further increase of pancreatic enzymes. We tried to continue the treatment by reducing the dose but only the discontinuation was associated with normalization of amylase and lipase's levels. On the other hand the treatment with pazopanib got prolonged response of the disease in the absence of signs of pancreatitis. We therefore decided to continue treatment with pazopanib 400 mg daily with close monitoring of blood levels of pancreatic enzymes. CONCLUSIONS: We hypothesize that the increase of pancreatic enzymes is not a dose-dependent event. The mechanism for pancreatic toxicity induced by tyrosine-kinase inhibitors is unknown and no predictive factors have been identified. There are no clear guidelines on the management of the drug in the presence of pancreatic enzyme increase. In any case, we believe that a careful monitoring of pancreatic enzymes during treatment with pazopanib is advisable.

The changes of lipid metabolism in advanced renal cell carcinoma patients treated with everolimus: a new pharmacodynamic marker?

BACKGROUND: Everolimus is a mammalian target of rapamycin (mTOR) inhibitor approved for the treatment of metastatic renal cell carcinoma (mRCC). We aimed to assess the association between the baseline values and treatmentrelated modifications of total serum cholesterol (C), triglycerides (T), body mass index (BMI), fasting blood glucose level (FBG) and blood pressure (BP) levels and the outcome of patients treated with everolimus for mRCC. METHODS: 177 patients were included in this retrospective analysis. Time to progression (TTP), clinical benefit (CB) and overall survival (OS) were evaluated. RESULTS: Basal BMI was significantly higher in patients who experienced a CB (p=0,0145). C,T and C+T raises were significantly associated with baseline BMI (p=0.0412, 0.0283 and 0.0001). Median TTP was significantly longer in patients with T raise compared to patients without T (10 vs 6, p=0.030), C (8 vs 5, p=0.042) and C+T raise (10.9 vs 5.0, p=0.003). At the multivariate analysis, only C+T increase was associated with improved TTP (p=0.005). T raise (21.0 vs 14.0, p=0.002) and C+T increase (21.0 vs 14.0, p=0.006) were correlated with improved OS but were not significant at multivariate analysis. CONCLUSION: C+T raise is an early predictor for everolimus efficacy for patients with mRCC.

Bone metastases in patients with metastatic renal cell carcinoma: are they always associated with poor prognosis?

PURPOSE: Aim of this study was to investigate for the presence of existing prognostic factors in patients with bone metastases (BMs) from RCC since bone represents an unfavorable site of metastasis for renal cell carcinoma (mRCC). MATERIALS AND METHODS: Data of patients with BMs from RCC were retrospectively collected. Age, sex, ECOG-Performance Status (PS), MSKCC group, tumor histology, presence of concomitant metastases to other sites, time from nephrectomy to bone metastases (TTBM, classified into three groups: <1 year, between 1 and 5 years and >5 years) and time from BMs to skeletal-related event (SRE) were included in the Cox analysis to investigate their prognostic relevance. RESULTS: 470 patients were enrolled in this analysis. In 19 patients (4%),bone was the only metastatic site; 277 patients had concomitant metastases in other sites. Median time to BMs was 16 months (range 0 - 44y) with Median OS of 17 months. Number of metastatic sites (including bone, p = 0.01), concomitant metastases, high Fuhrman grade (p < 0.001) and non-clear cell histology (p = 0.013) were significantly associated with poor prognosis. Patients with TTBM >5 years had longer OS (22 months) compared to patients with TTBM <1 year (13 months) or between 1 and 5 years (19 months) from nephrectomy (p < 0.001), no difference was found between these two last groups (p = 0.18). At multivariate analysis, ECOG-PS, MSKCC group and concomitant lung or lymph node metastases were independent predictors of OS in patients with BMs. CONCLUSIONS: Our study suggest that age, ECOG-PS, histology, MSKCC score, TTBM and the presence of concomitant metastases should be considered in order to optimize the management of RCC patients with BMs.

Natural history of malignant bone disease in hepatocellular carcinoma: final results of a multicenter bone metastasis survey.

BACKGROUND: Bone is an uncommon site of metastasis in patients with advanced hepatocellular carcinoma (HCC). Therefore, there are few studies concerning the natural history of bone metastasis in patients with HCC. PATIENTS AND METHODS: Data on clinicopathology, survival, skeletal-related events (SREs), and bone-directed therapies for 211 deceased HCC patients with evidence of bone metastasis were statistically analyzed. RESULTS: The median age was 70 years; 172 patients were male (81.5%). The median overall survival was 19 months. The median time to the onset of bone metastasis was 13 months (22.2% at HCC diagnosis); 64.9% patients had multiple bone metastases. Spine was the most common site of bone metastasis (59.7%). Most of these lesions were osteolytic (82.4%); 88.5% of them were treated with zoledronic acid. At multivariate analysis, only the Child Score was significantly correlated with a shorter time to diagnosis of bone metastases (p = 0.001, HR = 1.819). The median survival from bone metastasis was 7 months. At multivariate analysis, HCC etiology (p = 0.005), ECOG performance status (p = 0.002) and treatment with bisphosphonate (p = 0.024) were associated with shorter survival after bone disease occurrence. The site of bone metastasis but not the number of bone lesions was associated with the survival from first skeletal related event (SRE) (p = 0.021) and OS (p = 0.001). CONCLUSIONS: This study provides a significant improvement in the understanding the natural history of skeletal disease in HCC patients. An early and appropriate management of these patients is dramatically needed in order to avoid subsequent worsening of their quality of life.

Modification of abdominal fat distribution after aromatase inhibitor therapy in breast cancer patients visualized using 3-D computed tomography volumetry.

INTRODUCTION/BACKGROUND: The purpose of this study was to describe modification of subcutaneous adipose tissue (SAT) and visceral adipose tissue (VAT) distributions in breast cancer patients after aromatase inhibitor (AI) therapy using computed tomography (CT) volumetric measurement of abdominal body fat distribution. PATIENTS AND METHODS: Sixty-four consecutive patients who were receiving adjuvant AI therapy were included in this study. Patients were evaluated using CT before and after at least 6 months of AI therapy with imaging follow-up of 4.3 ± 2.2 years. Abdominal fat distribution was automatically calculated using a workstation that obtained total abdominal adipose tissue (TAAT) area (mm(3)). SAT was manually segmented and VAT was determined as TAAT - SAT. Percentages were calculated for change of TAAT, VAT, and SAT. VAT/SAT ratio was calculated. RESULTS: Percentage of TAAT after AI therapy was increased by a mean of 9.1% from baseline (16,280.3 ± 6953.3 mm(3)) to (17,763.6 ± 6850.8 mm(3)). Two groups of patients were observed; those with an increase in TAAT and those with a decrease. Modification of VAT/SAT ratio was observed (from 1.38 to 1.69) in all subjects, reflecting a relative increased volume of VAT (mean, 18%) and slight mean reduction of SAT (mean 1.9%). CONCLUSION: In our study, therapy with AI in breast cancer patients was accompanied with a change in fat distribution to relatively greater VAT/SAT ratio in patients, regardless of whether they gained or lost weight after therapy. Because this pattern of fat distribution is associated with metabolic disorders, attention must be paid to these clinical manifestations in patients during their follow-up management.

Sunitinib in malignant melanoma: a treatment option only for KIT-mutated patients?

Sunitinib has previously been reported to be potentially effective in the treatment of malignant melanomas expressing c-KIT. Here we report on the case of a 77-year-old gentleman affected by a metastatic clear cell carcinoma of the kidney and a metastatic malignant melanoma with liver and lung metastases. Despite the negativity for CD117 and the absence of KIT amplification or mutations in the melanoma specimen, he achieved a partial response both in the lungs and in the liver while on sunitinib (50 mg once/day, 4 weeks on/2 weeks off) for the treatment of kidney cancer. To our knowledge, this represents the first evidence of sunitinib activity in KIT wild-type melanoma. Further studies should be performed to confirm these preliminary data.

The role of macrophages polarization in predicting prognosis of radically resected gastric cancer patients.

Tumour-associated Macrophages (TAM) present two different polarizations: classical (M1) characterized by immunostimulation activity and tumour suppression; alternative (M2) characterized by tumour promotion and immune suppression. In this retrospective study, we evaluated the correlation between the two forms of TAM with survival time in radically resected gastric cancer patients. A total of 52 chemo- and radio-naive patients were included. Two slides were prepared for each patient and double-stained for CD68/NOS2 (M1) or CD68/CD163 (M2) and five representative high-power fields per slide were evaluated for TAM count. The median value of the two macrophage populations density and the median value of M1/M2 ratio were used as cut-off. Twenty-seven patients with M1 density above-the-median had a significantly higher survival compared to those below the median. Twenty-six patients with M1/M2 ratio above the median showed median OS of 27.2 months compared to 15.5 months of the patients below the median. No association between M2 macrophage density and patient's outcome was found. In multivariate analysis, M1/M2 was a positive independent predictor of survival. The M1 macrophage density and M1/M2 ratio, as confirmed in multivariate analysis, are factors that can help in predicting patients survival time after radical surgery for gastric cancer.
