Perioperative anemia management in colorectal cancer patients:A pragmatic approach

Anemia,usually due to iron deficiency,is highly prevalent among patients with colorectal cancer.Inflammatory cytokines lead to iron restricted erythropoiesis further decreasing iron availability and impairing iron utilization.Preoperative anemia predicts for decreased survival.Allogeneic blood transfusion is widely used to correct anemia and is associated with poorer surgical outcomes,increased post-operative nosocomial infections,longer hospital stays,increased rates of cancer recurrence and perioperative venous thromboembolism.Infections are more likely to occur in those with low preoperative serum ferritin level compared to those with normal levels.A multidisciplinary,multimodal,individualized strategy,collectively termed Patient Blood Management,minimizes or eliminates allogeneic blood transfusion.This includes restrictive transfusion policy,thromboprophylaxis and anemia management to improve outcomes.Normalization of preoperative hemoglobin levels is a World Health Organization recommendation.Iron repletion should be routinely ordered when indicated.Oral iron is poorly tolerated with low adherence based on published evidence.Intravenous iron is safe and effective but is frequently avoided due to misinformation and misinterpretation concerning the incidence and clinical nature of minor infusion reactions.Serious adverse events with intravenous iron are extremely rare.Newer formulations allow complete replacement dosing in 15-60 min markedly facilitating care.Erythropoiesis stimulating agents may improve response rates.A multidisciplinary,multimodal,individualized strategy,collectively termed Patient Blood Management used to minimize or eliminate allogeneic blood transfusion is indicated to improve outcomes.

Is tuberculosis patients management improved in the integrated TB control model in West China?A survey in Guizhou Province,China

Background:Tuberculosis(TB)patient management(TPM)is crucial to improve patient compliance to treatment.The coverage of TPM delivered by TB dispensaries or Centers for Disease Control and Prevention(CDC)was not high under the previous CDC model of TB control in China.In the integrated TB control model in China,TB patient management(TPM)was mainly delivered by lay health workers(LHWs)in primary health care(PHC)sectors.This study aims to investigate TPM delivery in resource-limited western China and to identify factors affecting TPM delivery by LHWs under the integrated TB control model.Methods:A stratified random sampling was used to select study sites.Pulmonary TB(PTB)patients≥15 years old from selected counties/districts in Guizhou Province were surveyed from August 2015 to May 2016.Structured questionnaires were used to collect data.Aχ^2 test and logistic regression were used to identify factors associated with self-administered treatment(non-TPM).Results:In total,638 PTB patients were included in the final analysis.Close to 30%of patients were ethnic minorities.More than 30%of patients were from counties with high TB burden,and 24.9%of patients had poor compliance to treatment.Only 37.1%of patients received TPM delivered by LHWs under the integrated TB control model throughout the treatment period.The main reasons for unwillingness to manage reported by patients included social stigma and no perceived need.Being ethnic minorities(OR=3.35)was a main factor associated with lower likelihood of receiving TPM,while living in areas with middle or high TB burden may increase the likelihood of receiving TPM(OR=0.17 and 0.25,respectively).Among current management approaches,more than 85%of patients chose phone reminder as their preferred TPM by LHWs.Conclusions:TPM under the integrated model in West China is still low and need further improvement,and the impeding factors of TPM need to be addressed.Strengthening patient-centered and community-based TPM and developing more feasible approaches of TPM delivery should be explored in future research in this region.

Management of neurosurgical patients during coronavirus disease 2019 pandemics:The Ljubljana,Slovenia experience

The novel coronavirus disease 2019(COVID-19)is an emerging disease,caused by severe acute respiratory syndrome coronavirus-2.It bears unique biological characteristics,clinical symptoms and imaging manifestations,therefore presenting an important and urgent threat to global health.As a result,a new public health crisis arose,threatening the world with the spread of the 2019 novel coronavirus.Despite the maximal worldwide public health responses aimed at containing the disease and delaying its spread,many countries have been confronted with a critical care crisis,and even more,countries will almost certainly follow.In Slovenia,the COVID-19 has struck the health system immensely and among all the specialities,neurosurgery has also been experiencing difficulties in the service,not only in regular,elective surgeries but especially during emergencies.The management of these neurosurgical patients has become more difficult than ever.We describe our protocol in the management of neurosurgical patients in the University Medical Centre Ljubljana,Slovenia and how neurosurgical pathology was tackled during the pandemics.

Hemodynamic monitoring and management of patients undergoing high-risk surgery:a survey among Chinese anesthesiologists

Hemodynamic monitoring and optimization improve postoperative outcome during high-risk surgery.However,hemodynamic management practices among Chinese anesthesiologists are largely unknown.This study sought to evaluate the current intraoperative hemodynamic management practices for high-risk surgery patients in China.From September 2010 to November 2011,we surveyed anesthesiologists working in the operating rooms of 265 hospitals representing 28 Chinese provinces.All questionnaires were distributed to department chairs of anesthesiology or practicing anesthesiologists.Once completed,the 29-item questionnaires were collected and analyzed.Two hundred and 10 questionnaires from 265 hospitals in China were collected.We found that 91.4%of anesthesiologists monitored invasive arterial pressure,82.9%monitored central venous pressure（CVP）,13.3%monitored cardiac output（CO）,10.5%monitored mixed venous saturation,and less than 2%monitored pulse pressure variation（PPV） or systolic pressure variation（SPV） during high-risk surgery.The majority（88%） of anesthesiologists relied on clinical experience as an indicator for volume expansion and more than 80%relied on blood pressure,CVP and urine output.Anesthesiologists in China do not own enough attention on hemodynamic parameters such as PPV,SPV and CO during fluid management in high-risk surgical patients.The lack of CO monitoring may be attributed largely to the limited access to technologies,the cost of the devices and the lack of education on how to use them.There is a need for improving access to these technologies as well as an opportunity to create guidelines and education for hemodynamic optimization in China.

Characteristics of management of reproductive endocrine problems in female patients

In 1956, my former Head and Professor of the Department of Obstetrics and Gynecology KT LIM, asked me to take the initiative to establish a reproductive endocrinology unit. As China is a developing country, we were then short of diagnostic facilities and therapeutic agents. We can learn basic knowledge and clinical experiences from the literature, but hormonal preparations were expensive and generally most of our patients were poor. We needed to find simpler, inexpensive and yet effective ways to treat our patients. In a word, we had to develop our own way.……

Amelanotic primary cervical malignant melanoma:A case report and review of literature

BACKGROUND Primary malignant melanoma of the cervix(PMMC)is an extremely rare disease that originates from primary cervical malignant melanoma and frequently re-presents a challenge in disease diagnosis due to unclarified clinical and histo-logical presentations,particularly those without melanin.CASE SUMMARY Here,we report a case of amelanotic PMMC,with a history of breast cancer and thyroid carcinoma.The patient was finally diagnosed by immunohistochemical staining and staged as IB2 based on the International Federation of Gynecology and Obstetrics with reference to National Comprehensive Cancer Network guide-lines and was treated with radical hysterectomy,bilateral salpingo-oophorectomy and pelvic lymphadenectomy.She then received combination therapy consisting of immunotherapy with tislelizumab and radiofrequency hyperthermia.She has remained free of disease for more than 1 year.CONCLUSION The differential diagnosis process reenforced the notion that immunohisto-chemical staining is the most reliable approach for amelanotic PMMC diagnosis.Due to the lack of established therapeutic guidelines,empirical information from limited available studies does not provide the rationale for treatment-decision making.By integrating'omics'technologies and patient-derived xenografts or mini-patient-derived xenograft models this will help to identify selective thera-peutic window(s)and screen the appropriate therapeutics for targeted therapies,immune checkpoint blockade or combination therapy strategies effectively and precisely that will ultimately improve patient survival.

Transfusion and coagulation management in liver transplantation

There is wide variation in the management of coagulation and blood transfusion practice in liver transplantation. The use of blood products intraoperatively is declining and transfusion free transplantations take place ever more frequently. Allogenic blood products have been shown to increase morbidity and mortality. Primary haemostasis, coagulation and fibrinolysis are altered by liver disease. This, combined with intraoperative disturbances of coagulation, increases the risk of bleeding. Meanwhile, the rebalancing of coagulation homeostasis can put patients at risk of hypercoagulability and thrombosis. The application of the principles of patient blood management to transplantation can reduce the risk of transfusion. This includes: preoperative recognition and treatment of anaemia, reduction of perioperative blood loss and the use of restrictive haemoglobin based transfusion triggers. The use of point of care coagulation monitoring using whole blood viscoelastic testing provides a picture of the complete coagulation process by which to guide and direct coagulation management. Pharmacological methods to reduce blood loss include the use of anti-fibrinolytic drugs to reduce fibrinolysis, and rarely, the use of recombinant factor VIIa. Factor concentrates are increasingly used; fibrinogen concentrates to improve clot strength and stability, and prothrombin complex concentrates to improve thrombin generation. Non-pharmacological methods to reduce blood loss include surgical utilisation of the piggyback technique and maintenance of a low central venous pressure. The use of intraoperative cell salvage and normovolaemic haemodilution reduces allogenic blood transfusion. Further research into methods of decreasing blood loss and alternatives to blood transfusion remains necessary to continue to improve outcomes after transplantation.

Analysis on Nutritional Risk Screening and Influencing Factors of Hospitalized Patients in Central Urban Area

Rational nutritional support shall be based on nutritional screening and nutritional assessment. This study is aimed to explore nutritional risk screening and its influencing factors of hospitalized patients in central urban area. It is helpful for the early detection of problems in nutritional supports, nutrition management and the implementation of intervention measures, which will contribute a lot to improving the patient＇s poor clinical outcome. A total of three tertiary medical institutions were enrolled in this study. From October 2015 to June 2016, 1202 hospitalized patients aged ≥18 years were enrolled in Nutrition Risk Screening 2002（NRS2002） for nutritional risk screening, including 8 cases who refused to participate, 5 cases of same-day surgery and 5 cases of coma. A single-factor chi-square test was performed on 312 patients with nutritional risk and 872 hospitalized patients without nutritional risk. Logistic regression analysis was performed with univariate analysis（P〈0.05）, to investigate the incidence of nutritional risk and influencing factors. The incidence of nutritional risk was 26.35% in the inpatients, 25.90% in male and 26.84% in female, respectively. The single-factor analysis showed that the age ≥60, sleeping disorder, fasting, intraoperative bleeding, the surgery in recent month, digestive diseases, metabolic diseases and endocrine system diseases had significant effects on nutritional risk（P〈0.05）. Having considered the above-mentioned factors as independent variables and nutritional risk（Y=1, N=0） as dependent variable, logistic regression analysis revealed that the age ≥60, fasting, sleeping disorders, the surgery in recent month and digestive diseases are hazardous factors for nutritional risk. Nutritional risk exists in hospitalized patients in central urban areas. Nutritional risk screening should be conducted for inpatients. Nutritional intervention programs should be formulated in consideration of those influencing factors, which enable to reduce the nutritional risk and to promote the rehabilitation of inpatients.

Advances in telemedicine for the management of the elderly cardiac patient

Telemedicine is the use of information and communication technology to deliver healthcare at a distance.It has been resorted to during the COVID-19 pandemic to lessen the need for in-person patient care decreasing the risk of transmission,and it can be of benefit afterward in the management of cardiac disease.The elderly population has unique challenges concerning the use of telehealth technologies.We thus review the advances in telemedicine technologies in treating elderly cardiac patients including in our discussion only studies with a mean age of participants above 60.Remote monitoring of blood pressure,weight,and symptoms,along with home ECG recording has been found to be superior to usual in-clinic follow up.Combining remote monitoring with video conferencing with physicians,patient education websites,and applications is also of benefit.Remote monitoring of Implantable Cardioverter Defibrillators(ICD)and Cardiac Resynchronization Therapy Defibrillators(CRT-D)is also beneficial but can be at the cost of an increase in both appropriate and inappropriate interventions.Implantable sensing devices compatible with remote monitoring have been developed and have been shown to improve care and cost-effectiveness.New smartphone software can detect arrhythmias using home ECG recordings and can detect atrial fibrillation using smartphone cameras.Remote monitoring of implanted pacemakers has shown non-inferiority to in clinic follow up.On the other hand,small-scale questionnaire-based studies demonstrated the willingness of the elderly cardiac patients to use such technologies,and their satisfaction with their use and ease of use.Large-scale studies should further investigate useability in samples more representative of the general elderly population with more diverse socioeconomic and educational backgrounds.Accordingly,it seems that studying integrating multiple technologies into telehealth programs is of great value.Further efforts should also be put in validating the technologies for specific diseases along with the legal and reimbursement aspects of the use of telehealth.

Chinese expert consensus on prevention and treatment of delayed nausea and vomiting(2022 Edition)

Nausea and vomiting are common adverse reactions of antitumor therapy,among which chemotherapy-induced nausea and vomiting(CINV)has been studied most intensively.Because of insufficient prevention or insufficient attention,CINV brings a series of harms to can-cer patients and even lead to the delay or termination of antitumor therapy.Delayed CINV is often underestimated because it mostly occurs outside the hospital,and patients cannot report it immediately.In recent years,the proportion of outpatient chemotherapy and day-time chemotherapy patients in China has increased year by year.Therefore,the prevention of delayed CINV is particularly important.Currently,the challenges faced by delayed CINV include the need to deeply explore its physiological and pathological mechanisms,improve its risk assessment standards,and optimize its prevention programs.However,there is still lack of practice guidelines or consensus on delayed CINV.Therefore,the Committee of Neoplastic Supportive-Care of China Anti-Cancer Association organized multidisciplinary experts in this field to formulate this consensus based on the analysis and discussion of current evidence-based medical research in combination with clinical problems that need to be solved urgently.

γ-glutamyl transferase-to-platelet ratio based nomogram predicting overall survival of gallbladder carcinoma

BACKGROUND Gallbladder carcinoma(GBC)carries a poor prognosis and requires a prediction method.Gamma-glutamyl transferase–to–platelet ratio(GPR)is a recently reported cancer prognostic factor.Although the mechanism for the relationship between GPR and poor cancer prognosis remains unclear,studies have demonstrated the clinical effect of both gamma-glutamyl transferase and platelet count on GBC and related gallbladder diseases.AIM To assess the prognostic value of GPR and to design a prognostic nomogram for GBC.METHODS The analysis involved 130 GBC patients who underwent surgery at Peking Union Medical College Hospital from December 2003 to April 2017.The patients were stratified into a high-or low-GPR group.The predictive ability of GPR was evaluated by Kaplan–Meier analysis and a Cox regression model.We developed a nomogram based on GPR,which we verified using calibration curves.The nomogram and other prognosis prediction models were compared using timedependent receiver operating characteristic curves and the concordance index.RESULTS Patients in the high-GPR group had a higher risk of jaundice,were older,and had higher carbohydrate antigen 19-9 levels and worse postoperative outcomes.Univariate analysis revealed that GPR,age,body mass index,tumor–node–metastasis(TNM)stage,jaundice,cancer cell differentiation degree,and carcinoembryonic antigen and carbohydrate antigen 19-9 levels were related to overall survival(OS).Multivariate analysis confirmed that GPR,body mass index,age,and TNM stage were independent predictors of poor OS.Calibration curves were highly consistent with actual observations.Comparisons of timedependent receiver operating characteristic curves and the concordance index showed advantages for the nomogram over TNM staging.CONCLUSION GPR is an independent predictor of GBC prognosis,and nomogram-integrated GPR is a promising predictive model for OS in GBC.

Intraoperative Goal-Directed Therapies in Femoral and Pelvic Osteotomies in Children and In-Hospital Postoperative Outcomes

Background: Femoral and pelvic osteotomies are potential hemorrhagic interventions where transfusion requirements can be necessary. Objective: We undertook a secondary analysis of patients who underwent femoral and pelvic osteotomy in the initial cohort. The objective of this secondary analysis was to describe intraoperative and postoperative outcomes and to describe intraoperative management in these patients in terms of blood product management and fluid and hemodynamic therapy with the aim of implementing optimization management protocols for postoperative outcome improvement. Methods: A secondary analysis of patients who underwent femoral and pelvic osteotomy surgery was included in the initial retrospective study. Results: There were eighteen patients with a mean age of 104 ± 47.1 months. Four (22.2%) patients had intraoperative and/or postoperative complications. One patient (5.6%) had an intraoperative hemorrhagic shock, two patients (11.1%) had postoperative neurologic failure, and one patient (5.6%) had postoperative wound sepsis. The transfusion rate was 50% in nine patients. Conclusion: Femoral and pelvic osteotomies are interventions where blood, transfusion and fluid requirements can be increased;thus, this implies the necessity of a global patient blood management protocol with point-of-care tests and fluid- and hemodynamic-guided protocols with validated tools in children for intraoperative and postoperative outcome optimization.

Hypertension in the elderly： insights from recent research

Hypertension is a leading cause of mortality and morbidity around the world and,prevalence of hypertension is increasing with aging.Hypertension in the elderly is associated with increased occurrence rates of sodium sensitivity,isolated systolic hypertension,and ＇white coat effect＇.Arterial stiffness and endothelial dysfunction also increase with age.These factors should be considered in selecting antihypertensive therapy.The prime objective of this therapy is to prevent stroke.The fmdings of controlled trials show that there should be no cut-off age for treatment.A holistic program for controlling cardiovascular risks should be fully discussed with the patient,including evaluation to exclude underlying causes of secondary hypertension,and implementation of lifestyle measures.The choice of antihypertensive drug therapy is influenced by concomitant disease and previous medication history,but will typically include a thiazide diuretic as the first-line agent;to this will be added an angiotensin inhibitor and/or a calcium channel blocker.Beta blockers are not generally recommended,in part because they do not combat the effects of increased arterial stiffness.The hypertension-hypoten-sion syndrome requires case-specific management.Drug-resistant hypertension is important to differentiate from faulty compliance with medication.Patients resistant to the third-line drug therapy may benefit from treatment with extended-release isosorbide mononitrate.A trial of spironolactone may also be worthwhile.
