Background: Limited literature exists in India on WhatsApp use for health communication among frontline health workers like Auxiliary Nurse Midwives (ANM). We conducted this study to assess the adoption of WhatsApp among ANMs and identify factors influencing its adoption. In addition, the study explored the perceptions of ANMs on WhatsApp use for sharing health information. Methods: We employed a mixed-method sequential explanatory design. We surveyed 259 ANMs, followed by in-depth interviews with 19 purposively sampled ANMs. We conducted multinomial logistic regression to identify factors associated with WhatsApp adoption and employed thematic analysis to analyze interviews. Results: 257 ANMs responded to the survey questionnaire, of which 18.3%, 48.2%, and 33.5% had low, mid, and high levels of WhatsApp adoption, respectively. Education (AOR = 2.87 [95% CI = 1.20-6.85]), motivation (AOR = 6.31 [95% CI = 1.43-27.80]), and technical awareness (AOR = 2.91 [95% CI = 1.11-7.62]) were significantly associated with WhatsApp adoption. Thematic analysis of the interviews resulted in six themes describing perceptions and experiences of ANMs on WhatsApp use. They are: (i) a way of instant communication, (ii) provision for multimedia messaging, (iii) a quick fix tool for queries and concerns, (iv) make attendance and reporting easy (v) a way of reaching higher officials, and (vi) a cost-saving mechanism. Conclusion: WhatsApp facilitated ANMs' communication and service delivery at the grassroots level. Measures to improve motivation, technical awareness, and digital education will likely improve WhatsApp adoption among health workers.

Objective: The ketogenic diet (KD), a high-fat and low-carbohydrate diet, is effective for a subset of patients with drug-resistant epilepsy, although the mechanisms of the KD have not been fully elucidated. The aims of this observational study were to investigate comprehensive short-term metabolic changes induced by the KD and to explore candidate metabolites or pathways for potential new therapeutic targets. Methods: Subjects included patients with intractable epilepsy who had undergone the KD therapy (the medium-chain triglyceride [MCT] KD or the modified Atkins diet using MCT oil). Plasma and urine samples were obtained before and at 2-4 weeks after initiation of the KD. Targeted metabolome analyses of these samples were performed using gas chromatography-tandem mass spectrometry (GC/MS/MS) and liquid chromatography-tandem mass spectrometry (LC/MS/MS). Results: Samples from 10 and 11 patients were analysed using GC/MS/MS and LC/MS/MS, respectively. The KD increased ketone bodies, various fatty acids, lipids, and their conjugates. In addition, levels of metabolites located upstream of acetyl-CoA and propionyl-CoA, including catabolites of branched-chain amino acids and structural analogues of γ-aminobutyric acid and lactic acid, were elevated. Conclusions: The metabolites that were significantly changed after the initiation of the KD and related metabolites may be candidates for further studies for neuronal actions to develop new anti-seizure medications.

Although there are some reports highlighting the applicability of double plates in distal femoral fractures, there is no standard approach or fixation method for supracondylar fractures combined with posterior coronal shear fractures. We report a case of distal femoral fracture treated with a lateral locking plate and posterior buttress plate using anterolateral and posterolateral approaches from one incision. A 70-year-old man was hit by a motorcycle and had an intra-articular distal femoral fracture involving a long medial proximal spike and a single lateral condyle fragment, with the lateral condyle fragment posteriorly displaced. A 12-cm lateral skin incision was made, and the joint was developed using a para-patellar approach from the anterior to iliotibial band. Posterior buttress plate fixation was successfully performed from behind the iliotibial band using a posterolateral approach, followed by cannulated cancellous screw and lateral locking plate fixation from the anterolateral window. Combined anterolateral and posterolateral approaches from one incision enable intra-articular exposure and fixation based on fixation principles for lateral condyle fragments combined with supracondylar fracture.

Preoperative assessment of the degree of liver fibrosis is important to determine treatment strategies. In this study, galactosyl human serum albumin single-photon emission-computed tomography and ethoxybenzyl (EOB) contrast-enhanced magnetic resonance imaging (MRI) were used to assess the changes in hepatocyte function after liver fibrosis, and the standardized uptake value (SUV) was combined with gadolinium EOB-diethylenetriaminepentaacetic acid to evaluate its added value for liver fibrosis staging. A total of 484 patients diagnosed with hepatocellular carcinoma who underwent liver resection between January 2010 and August 2018 were included. Resected liver specimens were classified based on pathological findings into nonfibrotic and fibrotic groups (stratified according to the Ludwig scale). Galactosyl human serum albumin-single-photon emission-computed tomography and EOB contrast-enhanced MRI examinations were performed, and the mean SUVs (SUVmean) and contrast enhancement indices (CEIs) were obtained. The diagnostic value of the acquired SUV and CEIs for fibrosis was assessed by calculating the area under the receiver operating characteristic curve (AUC). In the receiver operating characteristic analysis, SUV + CEI showed the highest AUC in both fibrosis groups. In particular, in the comparison between fibrosis groups, SUV + CEI showed significantly higher AUCs than SUV and CEI alone in discriminating between fibrosis (F3 and 4) and no or mild fibrosis (F0 and 2) (AUC: 0.879, vs SUV [P = 0.008], vs. CEI [P = 0.023]), suggesting that the combination of SUV + CEI has greater diagnostic performance than the individual indices. Combining the SUV and CEI provides high accuracy for grading liver fibrosis, especially in differentiating between grades F0 and 2 and F3-4. SUV and gadolinium EOB-diethylenetriaminepentaacetic acid-enhanced MRI can be noninvasive diagnostic methods to guide the selection of clinical treatment options for patients with liver diseases.

746 Background: Depth of response (DpR; max% reduction from baseline in sum of target lesion diameters), has been reported to be associated with improved prognosis in several malignancies. However, there have been few reports regarding DpR in patients with locally advanced pancreatic cancer (LAPC). Thus, we investigated the association between DpR and overall survival (OS), and whether there were any differences in treatment efficacy on DpR between modified FOLFIRINOX (mFFX) versus gemcitabine plus nab-paclitaxel (GnP) as 1st-line chemotherapy for LAPC, using the results from JCOG1407 which was a randomized phase II trial comparing these regimens. Methods: Of the 126 patients enrolled in JCOG1407, patients were eligible except for the followings; patients who never had an imaging study or had only non-target lesions. The association between DpR and OS was investigated by dividing DpR into 3 groups at the tertile point (T1, T2 and T3 from largest to smallest), and whether DpR contributes to OS was examined by multivariable analysis. The differences in treatment efficacy between both regimens were investigated byevaluating DpR, time to DpR, and duration of response (DoR). Results: A total of 109 patients were eligible for this study (n = 53/56 in mFFX/GnP). The number of patients in T1, T2, and T3 were 37, 36, and 36, respectively. The median OS of T1, T2, and T3 were 29.3 (95% CI, 21.0-NE), 20.6 (95% CI, 15.8-24.5), and 19.0 months (95% CI, 12.7-22.4), respectively ( P= 0.0237). Multivariable analysis identified DpR as an independent prognostic factor for OS (HR 1.883, 95% CI 1.030-3.442, P= 0.040 for T2 vs. T1, and HR 2.523, 95% CI 1.342-4.744, P= 0.004 for T3 vs. T1). The median DpR in GnP was better than that in mFFX (28.9 vs. 22.7%; P= 0.041). The median DoR in mFFX tended to be longer compared to that in GnP (8.2 vs. 5.3 months; P= 0.132). No differences in mean time to DpR were observed between the two regimens. Conclusions: In LAPC patients receiving 1st-line chemotherapy, larger DpR contributed to OS. Although OS and PFS between mFFX and GnP were similar, the treatment efficacy on DpR and DoR might be different between the two regimens. Clinical trial information: UMIN000023143 .

197 Background: The prognostic relevance of primary tumor sidedness (PTS) in early-stage colorectal cancer (CRC) is still debated. Several epidemiologic studies have yielded different results due to the wide variation in the quality of CRC surgery and perioperative management. This integrated analysis aimed to investigate the true prognostic relevance of PTS in stage II/III CRC among patients who received standardized surgery and perioperative management. Methods: This analysis included patients from 4 randomized controlled trials (RCTs) conducted by the Japan Clinical Oncology Group (JCOG): JCOG0205, JCOG0404, JCOG0910, and JCOG1006. All patients enrolled in these RCTs received standardized surgery with Japanese D2/D3 lymphadenectomy, and adjuvant 5-FU monotherapy was planned for all stage III patients as a protocol treatment. The data were collated, and patients with stage II/III adenocarcinoma of the colon and upper rectum were identified. For comparison, all eligible patients were categorized into a right-sided (cecum to transverse colon) group or a left-sided (descending colon to upper rectum) group. Primary outcome measures were relapse-free survival (RFS) and overall survival (OS) after primary surgery, and secondary outcome measures included OS after recurrence. Results: A total of 4,113 patients from the 4 RCTs satisfied the eligibility criteria and were divided into two groups; 1,349 right-sided and 2,764 left-sided CRC patients. Five-year RFS after primary surgery for right-sided and left-sided CRC was 79.7% and 79.9% in all patients, 89.7% and 86.9% in stage II and 77.0% and 78.3% in stage III, respectively. There was no significant difference in RFS after adjustment for patient and treatment characteristics (HR adjusted 1.024 [95% CI 0.886-1.183] in all patients, 1.327 [0.852-2.067] in stage II and 0.990 [0.850-1.154] in stage III). Five-year OS after primary surgery was 89.7% and 91.7% in all patients, 97.2% and 96.0% in stage II and 87.6% and 90.7% in stage III, respectively. There was also no remarkable difference in OS after adjustment (HR adjusted 0.879 [95% CI 0.726-1.064] in all patients, 1.517 [0.738-3.115] in stage II and 0.840 [0.689-1.024] in stage III). In total, 795 patients, including 257 right-sided and 538 left-sided CRC, had any recurrence after primary surgery. Five-year OS after a recurrence of right-sided and left-sided CRC were 39.8% and 49.8%, respectively. After adjustment, right-sided CRC had significantly worse OS after recurrence (HR adjusted 0.773 [95% CI 0.627-0.954]). Conclusions: Our results provide more robust evidence for no impact of PTS on recurrence risk and survival after standard surgery and perioperative management for stage II/III CRC. These results indicate that treatment stratification based on PTS is not necessary in early-stage CRC.

Background Postpartum hemolysis, elevated liver enzymes, and low platelet count (HELLP) syndrome is more difficult to treat than HELLP syndrome during pregnancy. We describe a case of postpartum HELLP syndrome that responded to plasma exchange (PE) therapy. Case presentation A 30-year-old primipara woman was hospitalized for gestational hypertension at 33 weeks of gestation and underwent an emergent cesarean section at 36 weeks and 6 days of gestation due to rapidly progressing pulmonary edema. After delivery, liver dysfunction and a rapid decrease in platelet count were observed, and the patient was diagnosed with severe HELLP syndrome. She experienced multiple organ failure despite intensive care, and PE therapy was initiated. Her general condition dramatically stabilized within a few hours of PE therapy. Conclusion It is controversial whether PE therapy should be used primarily in the management of HELLP syndrome, but early initiation of PE therapy could be effective for severe HELLP syndrome.

We report a case of ipsilateral periprosthetic fractures above and below the knee that occurred at different times due to navigation tracker pin and bone fragility. A 66-year-old Japanese woman with rheumatoid arthritis (RA) underwent a total knee arthroplasty. Four months post-surgery, a periprosthetic fracture above the knee at the navigation pin hole was detected. She underwent osteosynthesis and could walk independently, but she developed an ipsilateral tibial component fracture. Conservative treatment with a splint was followed by bone union. Patients with RA treated with oral steroids tend to develop ipsilateral periprosthetic fractures around the knee due to bone fragility.

Background: In children with intermediate-risk relapsed acute lymphoblastic leukemia (ALL), allogeneic hematopoietic stem cell transplantation (allo-HSCT) has markedly improved the outcome of patients with poor minimal residual disease (MRD) response. However, there is no consensus on the optimal conditioning regimen for allo-HSCT. Procedure: We prospectively analyzed the efficacy and safety of allo-HSCT with a unified conditioning regimen for children with intermediate-risk relapsed ALL, based on MRD in the bone marrow after induction, in the Japanese Pediatric Leukemia/Lymphoma Study Group (JPLSG) ALL-R08-II nationwide cohort. The conditioning regimen for allo-HSCT comprised total body irradiation (TBI), etoposide (ETP) and cyclophosphamide (CY) (UMIN000002025). Results: Twenty patients with post-induction MRD ≥ 10 and two with MRD that could not be evaluated underwent allo-HSCT. Engraftment was confirmed in all patients. No transplantation-related mortality was observed. The 3-year event-free survival and overall survival after transplantation were 86.4% ± 7.3% and 95.5% ± 4.4%, respectively. Conclusion: Allo-HSCT based on post-induction MRD with TBI + ETP + CY conditioning was highly effective and feasible for Japanese children with intermediate-risk relapsed ALL.

This study was performed to evaluate the oncological impact of surgical site infection (SSI) and pneumonia on long‐term outcomes after esophagectomy. The Japan Society for Surgical Infection conducted a multicenter retrospective cohort study involving 407 patients with curative stage I/II/III esophageal cancer at 11 centers from April 2013 to March 2015. We investigated the association of SSI and postoperative pneumonia with oncological outcomes in terms of relapse‐free survival (RFS) and overall survival (OS). Ninety (22.1%), 65 (16.0%), and 22 (5.4%) patients had SSI, pneumonia, and both SSI and pneumonia, respectively. The univariate analysis demonstrated that SSI and pneumonia were associated with worse RFS and OS. In the multivariate analysis, however, only SSI had a significant negative impact on RFS (HR, 1.63; 95% confidence interval, 1.12–2.36; P = 0.010) and OS (HR, 2.06; 95% confidence interval, 1.41–3.01; P < 0.001). The presence of both SSI and pneumonia and the presence of severe SSI had profound negative oncological impacts. Diabetes mellitus and an American Society of Anesthesiologists score of III were independent predictive factors for both SSI and pneumonia. The subgroup analysis showed that three‐field lymph node dissection and neoadjuvant therapy canceled out the negative oncological impact of SSI on RFS. Our study demonstrated that SSI, rather than pneumonia, after esophagectomy was associated with impaired oncological outcomes. Further progress in the development of strategies for SSI prevention may improve the quality of care and oncological outcomes in patients undergoing curative esophagectomy. Our study demonstrated that SSI, rather than pneumonia, after esophagectomy was associated with impaired oncological outcomes. Further progress in the development of strategies for SSI prevention may improve the quality of care and oncological outcomes in patients undergoing curative esophagectomy.

Anteroposterior (AP) alignment assessment for nondisplaced femoral neck fractures is important for determining the treatment strategy and predicting postoperative outcomes. AP alignment is generally measured using the Garden alignment index (GAI). However, its reliability remains unknown. We compared the reliability of GAI and a new AP alignment measurement (valgus tilt measurement [VTM]) using preoperative AP radiographs of nondisplaced femoral-neck fractures. The study was designed as an intra- and inter-rater reliability analysis. The raters were four trauma surgeons who assessed 50 images twice. The main outcome was the intraclass correlation coefficient (ICC). To calculate intra- and inter-rater reliability, we used a mixed-effects model considering rater, patient and time. The overall ICC (95%CI) of GAI and VTM for intra-rater reliability was 0.92 (0.89–0.94) and 0.86 (0.82–0.89), respectively. The overall ICC of GAI and VTM for inter-rater reliability was 0.92 (0.89–0.95), and 0.85 (0.81–0.88), respectively. The intra- and inter-rater reliability of GAI was higher in patients aged <80 years than in patients aged ≥80 years. Our results showed that GAI is a more reliable measurement method than VTM, although both are reliable. Variations in patient age should be considered in GAI measurements.

We encountered a patient with an infection related to an implanted central venous port-catheter that necessitated removal of the system. As the catheter had tightly adhered to the venous wall, removal was impossible with standard methods. After trial and error, we used a guiding catheter that was advanced over the implanted catheter to detach the fibrin sheath on the implanted catheter that had adhered to the vessel wall. At that time, a pull-through technique was used. After we succeeded in detaching the adhesion with the guiding catheter, we were able to withdraw the implanted catheter.

Background Primary pancreatic cancer with synchronous primary tumors in other organs is a rare condition, and its treatment largely depends on the progression of pancreatic cancer. Here, we describe a rare case of double primary malignancies involving borderline resectable pancreatic body and extrahepatic bile duct cancers that were successfully resected after neoadjuvant chemotherapy (NAC), subsequently avoiding total pancreatectomy. Case presentation A 61-year-old Japanese male was referred to our hospital by his general practitioner after presenting with elevated liver enzymes during a routine check-up for type 2 diabetes mellitus. He was diagnosed with synchronous borderline resectable pancreatic cancer in the body of the pancreas and lower extrahepatic bile duct cancer with obstructive jaundice. Abdominal computed tomography (CT) confirmed a hypovascular mass in the pancreatic body with partial encasement of the common hepatic artery, left gastric artery, celiac artery, and splenic artery and invasion of the splenic vein. Endoscopic retrograde cholangiopancreatography and bile duct biopsy confirmed lower bile duct cancer. Following multidisciplinary discussion, endoscopic retrograde biliary drainage was performed, and neoadjuvant chemotherapy comprising gemcitabine plus nanoparticle albumin-bound paclitaxel (GEM + nab-PTX) was administered. After a total of seven cycles of chemotherapy, follow-up CT showed that the size of the pancreatic lesion reduced, following which the patient underwent pancreatoduodenectomy with splenic artery resection. The postoperative course was uneventful without any surgical complications or intensive hypoglycemic treatment. The pathological diagnosis was pancreatic ductal adenocarcinoma (ypT3N1aM0 ypStage IIB/UICC 8th) with synchronous extrahepatic cholangiocarcinoma (ypT2N1M0 ypStage IIB/UICC 8th). R0 pancreatic resection was performed with an Evans grade III response to neoadjuvant chemotherapy. The patient was followed up and had no tumor recurrence at 22 months after surgery with adjuvant S-1 chemotherapy, however, died after 32 months after surgery due to multiple liver metastasis and para-aortic lymph node metastasis despite salvage GEM + nab-PTX chemotherapy. Conclusion In our case, neoadjuvant chemotherapy for borderline resectable pancreatic cancer and function-preserving pancreatoduodenectomy (R0 resection) for double primary malignancies achieved balanced patient survival and postoperative quality of life.

Background Chylous ascites (CA) is a rare complication of gastrectomy for gastric cancer. While most cases of postoperative CA improve with medication or nutritional support, some are refractory to conservative treatment. A peritoneovenous shunt (PVS) may help patients who are poor candidates for surgery. However, PVS placement for postoperative CA after gastroenterological surgery has been rarely reported. Herein, we present a case of postoperative CA following total gastrectomy with para-aortic lymphadenectomy, treated successfully by PVS placement. Case presentation A 74-year-old man who underwent total gastrectomy with para-aortic lymph node dissection was hospitalised because of insufficient oral intake and dehydration. His abdomen was markedly distended with severe bilateral lower extremity oedema. On admission, abdominal computed tomography (CT) showed a high volume of ascites and no signs of cancer recurrence. Accordingly, postoperative CA resulting from drainage of fluid on paracentesis was diagnosed. Despite nutritional support, diuretics, and octreotide administration, his abdominal distension and nutritional status did not improve. We could not identify the sites of lymphatic leakage in the three intranodal lymphangiographies followed by CT. Although we considered a surgical treatment in our patient, we decided against it. Because we could not identify lymphatic leakage site during lymphangiography, surgical treatment might have a potential failure of detection and closure of leakage site. Furthermore, the patient’s general condition was poor because of malnutrition resulting from the loss of lymphatic fluid. Consequently, we decided to place PVS. After PVS placement, his abdominal distension improved rapidly, and he was discharged without serious complications. Thirteen months after PVS, patient has no relapse of abdominal distention and nutrition status has improved. Conclusion PVS might be a good option to manage refractory postoperative CA, as the leakage point cannot be detected on lymphangiography.

Background The usefulness of neoadjuvant chemotherapy for patients with duodenal adenocarcinoma remains unclear. We report the case of a successfully resected duodenal adenocarcinoma managed by neoadjuvant chemotherapy using gemcitabine and S-1. Case presentation A 72-year-old female presented with a one-week history of abdominal bloating and vomiting after meals. Esophagogastroduodenoscopy revealed a circumferential epithelial lesion in the second portion of the duodenum. Abdominal computed tomography scan revealed thickened walls and narrowing of the duodenum. Further, an adenocarcinoma was noted on biopsy. Though she was diagnosed with duodenal adenocarcinoma, pancreatic cancer could not be completely ruled out. Therefore, she underwent neoadjuvant chemotherapy using gemcitabine and S-1 after bypass surgery. After six chemotherapy cycles, the tumor significantly reduced in size. Further, lymph nodes and distant metastases were not noted on abdominal computed tomography. The patient underwent pancreaticoduodenectomy. Pathological examination revealed a 0.5-mm lesion and surrounding fibrosis at the duodenum, distal from the ampulla of Vater and the pancreas. Her postoperative course was almost uneventful, and she was discharged on the 31st postoperative day. The patient was followed up and had no tumor recurrence at 24 months after surgery. Conclusion Neoadjuvant chemotherapy with gemcitabine and S-1 was useful in reducing the size of a duodenal adenocarcinoma. This finding would aid physicians in managing patients that present with a similar presentation.

Objectives The spread through air spaces (STAS) of adenocarcinoma (ADC) is a unique pattern for local invasion, which comprises the spread of tumor cells within air spaces beyond the tumor edge without a direct connection with the primary tumor. Matrix metalloproteinase-7 (MMP-7), a secreted proteolytic enzyme that degrades various extracellular matrix components and other substrates, regulates several pathophysiological processes as well as the occurrence and development of cancers in humans. Here, we retrospectively analyzed a cohort of Japanese patients with treatment-naive, surgically-resected lung ADC to assess whether MMP-7 is associated with STAS development and if it could be used as a predictor of STAS. Materials and methods We performed histological evaluation using hematoxylin and eosin staining and immunohistochemical analysis using microarrays. Thereafter, we scored the examined tissues for immune markers to identify significant tumor STAS predictors. Results We identified that high MMP-7 expression is an independent predictor of a high STAS incidence. Multivariate analysis revealed that MMP-7 expression was correlated with tumor behavior and poor prognosis. Furthermore, STAS remained significantly associated with a higher risk of ADC recurrence. Conclusion The development of tumor STAS could be promoted by the functioning of MMP-7. This study could be a crucial basis for future investigations on the detection of tumor STAS.

Background It is unclear what interventions can sustain long-term higherphysical activity (PA) to improve breast cancer outcomes. Thus, this study aimed to evaluate the long-term effects of interventions on PA after breast cancer treatment. Methods This was an open-label randomized controlled trial for patients with stage 0-III breast cancer evaluating the efficacy of exercise and educational programs on long-term PA compared with usual care. The primary endpoint was proportion of patients with recreational PA (RPA) ≥5 metabolic equivalents(METs)/week at 1 year after registration. Results From 01/03/2016 to 15/03/2020, breast cancer patients were registered in the control (n = 120), education (n = 121), or exercise (n = 115) group. There were no significant differences in proportion of RPA ≥5 METs/week at 1 year between the exercise and control groups (54% and 53%, P = 0.492) and between the education and control groups (62% and 53%, P = 0.126). Significant difference in reductions from baseline at 1 year were noted on body weight (P = 0.0083), BMI (P = 0.0034), and body fat percentage (P = 0.0027) between education and control groups. Similarly, the exercise group showed significant difference in reduction in body fat percentage (P = 0.0038) compared to control group. Conclusions Although there were no significant effects on RPA 1 year after exercise and educational programs for breast cancer survivors, both interventions reduced body composition. Future studies on PA should investigate appropriate interventions to improve overall survival. Trial registration UMIN000020595 at UMIN Clinical Trial Registry Date of first registration: 01/03/2016

Survival remains poor even after resection of pancreatic cancer and the postoperative recurrence rate is extremely high. Thus, neoadjuvant treatment may improve outcomes for resectable pancreatic cancer (RPC). This study evaluated the efficacy of neoadjuvant therapy for radiologically judged RPC. A prospectively maintained institutional database was reviewed to identify patients who underwent potentially curative resection of radiologically judged RPC. Patient characteristics and intermediate-term outcomes were compared between groups that received neoadjuvant treatment or upfront surgery (UFS). We identified 353 eligible patients, including 55 patients who received neoadjuvant chemoradiotherapy (CRT group), 53 patients who received neoadjuvant gemcitabine plus nab-paclitaxel (GnP group), and 245 patients who underwent UFS (UFS group). The cumulative rates of pancreatic cancer recurrence at 2 years after pancreatic surgery were 49.5% in the UFS, 48.1% in the CRT group, and 52.7% in the GnP group. The recurrence rate tended to be improved after neoadjuvant treatment, although the difference was not significant at this follow-up point. While the clinical TNM classifications were noticeably different from the final pathological findings, the clinical and pathological TNM classifications were more similar in the groups that underwent neoadjuvant treatment. Neoadjuvant treatment can help identify good surgical candidates and avoid unnecessary laparotomy. Our results also suggest that neoadjuvant therapy might help improve the preoperative diagnostic accuracy for patients with RPC.

Objective To investigate the safety and efficacy of early rehabilitation in patients with aneurysmal subarachnoid hemorrhage (aSAH) patients. Methods One hundred eleven patients with aSAH admitted between April 2015 and March 2019, were retrospectively evaluated. The early rehabilitation program was introduced in April 2017 to actively promote mobilization and walking training for aSAH patients. Therefore, patients were divided into two groups (The conventional group (n = 55) and the early rehabilitation group (n == 56). Clinical characteristics, mobilization progression, and treatment variables were analyzed. Complications (rebleeding, symptomatic cerebral vasospasm, hydrocephalus, disuse complications,) and a modified Rankin Scale (mRS) at 90 days were compared in two groups. Factors associated with favorable outcomes (mRS≤2) at 90 days were also assessed. Results The early rehabilitation group had a significantly shorter span to first walking (9 vs. 5 days; P = 0.007). The prevalence of complications was not significantly increased in the early rehabilitation group. Approximately 40% of patients in both groups had pneumonia and urinary tract infections but significantly reduced antibiotic-administration days (13 vs. 6 days; P < 0.001). mRS at 90 days also showed significant improvement in the early rehabilitation group (3 vs. 2; P=0.01). Multivariate logistic regression analysis of favorable outcomes associated that the administration of the early rehabilitation program has a significant independent factor (odds ratio, 3.03; 95% confidence interval, 1.1-8.37). Conclusions Early rehabilitation for patients with aSAH can be feasible without increasing complication occurrences. The early rehabilitation program with active mobilization and walking training reduced antibiotic use and was associated with improved independence.
