ABSTRACT

Purpose@#Prehabilitation (PH) is purported to improve patients’ preoperative functional status. This systematic review and meta-analysis sought to compare short-term postoperative outcomes between patients who underwent a protocolized PH program and the existing standard of care among colorectal cancer patients awaiting surgery. @*Methods@#A search in MEDLINE/PubMed, the Cochrane Library, Embase, Scopus, and CINAHL was conducted to identify relevant articles. Repetitive and exhaustive combinations of MeSH search terms (“prehabilitation,” “colorectal cancer,” “colon cancer,” and “rectal cancer”) were used to identify randomized and nonrandomized studies comparing PH versus standard of care for colorectal cancer patients awaiting surgery. The primary outcomes included postoperative morbidity, length of hospital stay, and readmission rates. @*Results@#Seven studies including 1,042 colorectal cancer patients (PH, 382) were included. No significant differences were found in intraoperative outcomes. The postoperative complication rates were comparable between groups (Clavien-Dindo grades I and II: risk ratio, 0.82; 95% confidence interval, 0.62–1.07; P=0.15; Clavien-Dindo grades ≥III: risk ratio, 1.02; 95% confidence interval, 0.72–1.44; P=0.92). There were also no significant differences in length of hospital stay (P=0.21) or the risk of 30-day readmission (P=0.68). @*Conclusion@#Although PH does not appear to improve short-term postoperative outcomes following colorectal cancer surgery, the quality of evidence is impaired by the limited trials and heterogeneity. Thus, further large-scale trials are warranted to draw definitive conclusions and establish the long-term effects of PH.

ABSTRACT

Purpose@#This study compared the short- and long-term clinical outcomes of laser hemorrhoidoplasty (LH) vs. conventional hemorrhoidectomy (CH) in patients with grade II/III hemorrhoids. @*Methods@#PubMed/Medline and the Cochrane Library were searched for randomized and nonrandomized studies comparing LH against CH in grade II/III hemorrhoids. The primary outcomes included postoperative use of analgesia, postoperative morbidity (bleeding, urinary retention, pain, thrombosis), and time of return to work/daily activities. @*Results@#Nine studies totaling 661 patients (LH, 336 and CH, 325) were included. The LH group had shorter operative time (P0.999) and prolapse (P=0.240), and the likelihood of complete resolution at 12 months, were similar (P=0.240). @*Conclusion@#LH offers more favorable short-term clinical outcomes than CH, with reduced morbidity and pain and earlier return to work or daily activities. Medium-term symptom recurrence at 12 months was similar. Our results should be verified in future well-designed trials with larger samples.

ABSTRACT

Purpose@#This systematic review and meta-analysis compared the outcomes of the watch-and-wait (WW) approach versus radical surgery (RS) in rectal cancers with clinical complete response (cCR) after neoadjuvant chemoradiotherapy. @*Methods@#This study followed the PRISMA guidelines. Major databases were searched to identify relevant articles. WW and RS were compared through meta-analyses of pooled proportions. Primary outcomes included overall survival (OS), disease-free survival (DFS), local recurrence, and distant metastasis rates. Pooled salvage surgery rates and outcomes were also collected. The Newcastle-Ottawa scale was employed to assess the risk of bias. @*Results@#Eleven studies including 1,112 rectal cancer patients showing cCR after neoadjuvant chemoradiation were included. Of these patients, 378 were treated nonoperatively with WW, 663 underwent RS, and 71 underwent local excision. The 2-year OS (risk ratio [RR], 0.95; P = 0.94), 5-year OS (RR, 2.59; P = 0.25), and distant metastasis rates (RR, 1.05; P = 0.80) showed no significant differences between WW and RS. Local recurrence was more frequent in the WW group (RR, 6.93; P < 0.001), and 78.4% of patients later underwent salvage surgery (R0 resection rate, 97.5%). The 2-year DFS (RR, 1.58; P = 0.05) and 5-year DFS (RR, 2.07; P = 0.02) were higher among RS cases. However, after adjustment for R0 salvage surgery, DFS showed no significant between-group difference (RR, 0.82; P = 0.41). @*Conclusion@#Local recurrence rates are higher for WW than RS, but complete salvage surgery is often possible with similar long-term outcomes. WW is a viable strategy for rectal cancer with cCR after neoadjuvant chemoradiation, but further research is required to improve patient selection.

ABSTRACT

Objective To investigate the application value of case-based learning (CBL) combined with teaching rounds in the standardized training of residents in department of hematology. Methods A total of 124 residents who received standardized training in department of hematology from August 2015 to July 2018 were selected and randomly divided into experimental group and control group. The residents in the experimental group received the teaching method of CBL combined with teaching rounds, while those in the control group received traditional teaching rounds. The two groups were compared in terms of department examination scores and teaching quality. Results Compared with the control group, the experimental group had significantly higher scores of the department examinations of hematological theoretical knowledge and case analysis (P<0.05). The residents in the experimental group thought that the new teaching method of CBL combined with teaching rounds could stimulate their interest in learning hematological diseases, improve self-study abilities , help them to combine theoretical knowledge with clinical practice , enhance their knowledge of hematological diseases, and cultivate their clinical thinking ability. Conclusion CBL combined with teaching rounds has achieved good results in standardized training of residents in department of hematology, and thus it holds promise for application in standardized training of other specialties in internal medicine.

ABSTRACT

Objective To investigate clinical signifieances of serum levels of vascular endothelial growth factor (VEGF) in patients with diffuse large B-cell lymphoma (DLBCL) and to analyze the relationships with international prognostic index (IPI). Methods Serum levels of VEGF were measured by ELISA in 26 cases with newly diagnosed DLBCL and 9 cases with relapsed DLBCL. The clinical data of 26 patients were collected. According to the IPI, 26 patients were divided into two group: low risk group (IPI<2) and moderate to high risk group (IPI≥2). Results Compared with the normal controls, newly diagnosed and relapsed DLBCL had significantly higher VEGF serum levels (P <0.01). In the patients responding to CHOP or RCHOP regimen a significantly decrease in VEGF serum levels occurred, while in the patients who did not achieve complete remission(CR) there was no significant decrease. Furthermore, pretreatment serum levels of VEGF were significantly lower in CR group than in partial remission (PR) and no remission (NR) group. In addition, serum levels of VEGF were significantly elevated in the high risk group than those at the low risk group(P<0.01). Conclusion The serum levels of angiogenic factor VEGF are related to the development and progression of DLBCL. The VEGF combined with IPI can be used for evaluating the prognosis of DLBCL.

ABSTRACT

Immunohistochemistry was utilized to investigate the light and electron micros-copic localization of neurotensin-like (NT) immunoreactive amacrine cells in thechicken retina.The results showed that the NT-immunoreactive cell bodies wereoval and situated in either the second or third row of cells from the inner borderof the inner nuclear layer.The processes of such cells extended into the innerplexiform layer where they ramified as a fine plexus in sublamina 1 and as a denseplexus in sublamina 3 and 4.At the ultrastructural level,NT positive soma exhibited a rather dense and evenlydistributed immune reaction product throughout their cytoplasm.The nucleus ofNT-amacrine cells possessed a round,unindented nuclear membrane.NT positiveprocesses of such cells receive synaptic input from processes of unlabeled amacrineand bipolar cells.They formed synaptic output onto processes of nonimmuno-reactive amacrine cells and bipolar cells.Moreover,each of the above synapticrelationships were identified in each of sublamina 1 and 3 to 4 of the inner plexiform layer.In addition,NT positive processes fromed synaptic output to processesdevoid of synaptic vesicles,which may originated from ganglion cells.They alsoformed synaptic output to somas situated in the innermost cell row of the innernuclear layer.Identification of synaptic elements and retinal circuitry were also discussed.

ABSTRACT

The immunohistochemical single and double label techniques were used to study the localization and coexistence of immunoreaetive enkephalin (ENK) and somatostatin (SOM) in amacrine cells of the chicken retina. The single label experiments showed that certain SOM-immunoreactive amacrine cells are similar in morphology, location in the inner nuclear layer (INL) and the manner of processes ramified in the inner plexiform layer (IPL) to some ENK-immunoreactive amacrine cells, although the plexus of SOM-immunoreactive processes in sublamina 3 and 4 were not as dense as ENK-immunoreactive plexus and SOM-immunoreactive processes in sublamina 5 were not observed. The double label studies indicated that some amacrine cells showed both SOM and ENK positive immunoreactivity and some other amacrine cells showed only SOM or ENK positive immunoreactivity.The coexistence of two neuropeptides or a neuropeptide and a classical neurotransrnitter in the retinal amacrine cells were also discussed.
