Abstract
Nowadays, the pre-operative evaluation of older patients is a critical step in the decision-making process. Clinical assessment and care planning should be considered a whole process rather than separate issues. Clinicians should use validated tools for pre-operative risk assessment of older patients to minimize surgery-related morbidity and mortality and enhance care quality. Traditional pre-operative consultation often fails to capture the pathophysiological and functional profiles of older patients. The elderly's pre-operative evaluation should be focused on determining the patient's functional reserve and reducing any possible peri-operative risk. Therefore, older adults may benefit from the Comprehensive Geriatric Assessment (CGA) that allows clinicians to evaluate several aspects of elderly life, such as depression and cognitive disorders, social status, multi-morbidity, frailty, geriatric syndromes, nutritional status, and polypharmacy. Despite the recognized challenges in applying the CGA, it may provide a realistic risk assessment for post-operative complications and suggest a tailored peri-operative treatment plan for older adults, including pre-operative optimization strategies. The older adults' pre-operative examination should not be considered a mere stand-alone, that is, an independent stage of the surgical pathway, but rather a vital step toward a personalized therapeutic approach that may involve professionals from different clinical fields. The aim of this review is to revise the evidence from the literature and highlight the most important items to be implemented in the pre-operative evaluation process in order to identify better all elderly patients' needs.

Abstract
OBJECTIVE To develop evidence-based recommendations for safe, effective, and appropriate treatment of secondary (SHPT) and tertiary (THPT) renal hyperparathyroidism. BACKGROUND Hyperparathyroidism is common among patients with chronic kidney disease, end-stage kidney disease, and kidney transplant. The surgical management of SHPT and THPT is nuanced and requires a multidisciplinary approach. There are currently no clinical practice guidelines that address the surgical treatment of SHPT and THPT. METHODS Medical literature was reviewed from January 1, 1985 to present January 1, 2021 by a panel of 10 experts in SHPT and THPT. Recommendations using the best available evidence was constructed. The American College of Physicians grading system was used to determine levels of evidence. Recommendations were discussed to consensus. The American Association of Endocrine Surgeons membership reviewed and commented on preliminary drafts of the content. RESULTS These clinical guidelines present the epidemiology and pathophysiology of SHPT and THPT and provide recommendations for work-up and management of SHPT and THPT for all involved clinicians. It outlines the preoperative, intraoperative, and postoperative management of SHPT and THPT, as well as related definitions, operative techniques, morbidity, and outcomes. Specific topics include Pathogenesis and Epidemiology, Initial Evaluation, Imaging, Preoperative and Perioperative Care, Surgical Planning and Parathyroidectomy, Adjuncts and Approaches, Outcomes, and Reoperation. CONCLUSIONS Evidence-based guidelines were created to assist clinicians in the optimal management of secondary and tertiary renal hyperparathyroidism.

Abstract
Background Gait impairment is a debilitating and progressive feature of Parkinson’s disease (PD). Increasing evidence suggests that gait control is partly mediated by cholinergic signaling from the pedunculopontine nucleus (PPN). Objective We investigated whether PPN structural connectivity correlated with quantitative gait measures in PD. Methods Twenty PD patients and 15 controls underwent diffusion tensor imaging to quantify structural connectivity of the PPN. Whole brain analysis using tract-based spatial statistics and probabilistic tractography were performed using the PPN as a seed region of interest for cortical and subcortical target structures. Gait metrics were recorded in subjects’ medication ON and OFF states, and were used to determine if specific features of gait dysfunction in PD were related to PPN structural connectivity. Results Tract-based spatial statistics revealed reduced structural connectivity involving the corpus callosum and right superior corona radiata, but did not correlate with gait measures. Abnormalities in PPN structural connectivity in PD were lateralized to the right hemisphere, with pathways involving the right caudate nucleus, amygdala, pre-supplementary motor area, and primary somatosensory cortex. Altered connectivity of the right PPN-caudate nucleus was associated with worsened cadence, stride time, and velocity while in the ON state; altered connectivity of the right PPN-amygdala was associated with reduced stride length in the OFF state. Conclusion Our exploratory analysis detects a potential correlation between gait dysfunction in PD and a characteristic pattern of connectivity deficits in the PPN network involving the right caudate nucleus and amygdala, which may be investigated in future larger studies.

Abstract
BACKGROUND The aim of this study was to prospectively investigate the adherence to the American College of Cardiology (ACC) and the American Heart Association guidelines for perioperative assessment of patients with hip fracture in daily clinical practice and how this might affect outcome. METHODS This prospective cohort study from Maastricht University Medical Centre included 166 hip fracture patients within a 3-year inclusion period. The preoperative cardiac screening and adherence to the ACC/AHA guideline were analyzed. Cardiac risk was classified as low, intermediate and high risk. Secondary outcome measurements were delay to surgery, perioperative complications and in-hospital, 30-day, 1-year and 2-year mortality. RESULTS According to the ACC/AHA guideline, 87% of patients received correct preoperative cardiac screening. The most important reason for incorrect preoperative cardiac screening was overscreening (> 90%). Multivariate analysis showed that a cardiac consultation (p = 0.003) and overscreening (p = 0.02) as significant predictors for increased delay to surgery, while age, sex, previous cardiac history and preoperative mobility were not. High risk patients had in comparison with low risk patients a significantly higher relative risk ratio for in-hospital mortality (RR 6, 95% CI 2-17). Multivariate analysis showed that a previous cardiac history and increased delay to surgery were predictors for early mortality. High age and previous cardiac history were risk factors for late mortality. CONCLUSION Preoperative cardiac screening for hip fracture patients in adherence to the ACC/AHA guideline is associated with a diminished use of preoperative resources. Overscreening leads to greater delay to surgery, which poses a risk for perioperative complications and early mortality. LEVEL OF EVIDENCE II.

Abstract
PURPOSE General surgical procedures are among the most commonly performed operations in the United States. Despite advances in surgical and anesthetic techniques and perioperative care, complications after general surgery in older adults remain a significant cause of increased morbidity, mortality, and health care costs. Frailty, a geriatric syndrome characterized by multisystem physiologic decline and increased vulnerability to stressors and adverse clinical outcomes, has emerged as a plausible predictor of adverse outcomes after surgery in older patients. Thus, the goal of this topical review is to evaluate the evidence on the association between preoperative frailty and clinical outcomes after general surgery and whether frailty evaluation may have a role in surgical risk-stratification in vulnerable older patients. METHODS A PubMed database search was conducted between September and October 2018 to identify relevant studies evaluating the association between frailty and clinical outcomes after general surgery. Key words (frailty and surgery) and Medical Subject Heading term (general surgery) were used, and specific inclusion and exclusion criteria were applied. FINDINGS The available evidence from meta-analyses and cohort studies suggest that preoperative frailty is significantly associated with adverse clinical outcomes after emergent or nonemergent general surgery in older patients. Although these studies are limited by a high degree of heterogeneity of frailty assessments, types of surgery, and primary outcomes, baseline frailty appears to increase risk of postoperative complications and morbidity, hospital length of stay, 30-day mortality, and long-term mortality after general surgical procedures in older adults. IMPLICATIONS Evidence supports the further development of preoperative frailty evaluation as a risk-stratification tool in older adults undergoing general surgery. Research is urgently needed to quantify and differentiate the predictive ability of validated frailty instruments in the context of different general surgical procedures and medical acuity and in conjunction with existing surgical risk indices widely used in clinical practice. Practical applicability of frailty instrument as well as geriatrics-centered outcomes need to be incorporated in future studies in this line of research. Furthermore, clinical care pathways that integrate frailty assessment, geriatric medicine focused perioperative and postoperative management, and patient-centered interdisciplinary care models should be investigated as a comprehensive intervention approach in older adults undergoing general surgery. Finally, early implementation of palliative care should occur at the outset of hospital encounter in frail older patients who present with indications for emergent general surgery.

Abstract
BACKGROUND Perioperative hypertension requires careful management. Angiotensin-converting enzyme inhibitors (ACEIs) or angiotensin II type 1 receptor blockers (ARBs) have shown efficacy in treating hypertension associated with surgery. However, there is lack of consensus about whether they can prevent mortality and morbidity. OBJECTIVES To systematically assess the benefits and harms of administration of ACEIs or ARBs perioperatively for the prevention of mortality and morbidity in adults (aged 18 years and above) undergoing any type of surgery under general anaesthesia. SEARCH METHODS We searched the current issue of the Cochrane Central Register of Controlled Trials (CENTRAL; 2014, Issue 12), Ovid MEDLINE (1966 to 8 December 2014), EMBASE (1980 to 8 December 2014), and references of the retrieved randomized trials, meta-analyses, and systematic reviews. SELECTION CRITERIA We included randomized controlled trials (RCTs) comparing perioperative administration of ACEIs or ARBs with placebo in adults (aged 18 years and above) undergoing any type of surgery under general anaesthesia. We excluded studies in which participants underwent procedures that required local anaesthesia only, or participants who had already been on ACEIs or ARBs. DATA COLLECTION AND ANALYSIS Two review authors independently performed study selection, assessed the risk of bias, and extracted data. We used standard methodological procedures expected by Cochrane. MAIN RESULTS We included seven RCTs with a total of 571 participants in the review. Two of the seven trials involved 36 participants undergoing non-cardiac vascular surgery (infrarenal aortic surgery), and five involved 535 participants undergoing cardiac surgery, including valvular surgery, coronary artery bypass surgery, and cardiopulmonary bypass surgery. The intervention was started from 11 days to 25 minutes before surgery in six trials and during surgery in one trial. We considered all seven RCTs to carry a high risk of bias. The effects of ACEIs or ARBs on perioperative mortality and acute myocardial infarction were uncertain because the quality of the evidence was very low. The risk of death was 2.7% in the ACEIs or ARBs group and 1.6% in the placebo group (risk ratio (RR) 1.61; 95% confidence interval (CI) 0.44 to 5.85). The risk of acute myocardial infarction was 1.7% in the ACEIs or ARBs group and 3.0% in the placebo group (RR 0.55; 95% CI 0.14 to 2.26). ACEIs or ARBs may improve congestive heart failure (cardiac index) perioperatively (mean difference (MD) -0.60; 95% CI -0.70 to -0.50, very low-quality evidence). In terms of rate of complications, there was no difference in perioperative cerebrovascular complications (RR 0.48; 95% CI 0.18 to 1.28, very low-quality evidence) and hypotension (RR 1.95; 95% CI 0.86 to 4.41, very low-quality evidence). Cardiac surgery-related renal failure was not reported. ACEIs or ARBs were associated with shortened length of hospital stay (MD -0.54; 95% CI -0.93 to -0.16, P value = 0.005, very low-quality evidence). These findings should be interpreted cautiously due to likely confounding by the clinical backgrounds of the participants. ACEIs or ARBs may shorten the length of hospital stay, (MD -0.54; 95% CI -0.93 to -0.16, very low-quality evidence) Two studies reported adverse events, and there was no evidence of a difference between the ACEIs or ARBs and control groups. AUTHORS' CONCLUSIONS Overall, this review did not find evidence to support that perioperative ACEIs or ARBs can prevent mortality, morbidity, and complications (hypotension, perioperative cerebrovascular complications, and cardiac surgery-related renal failure). We found no evidence showing that the use of these drugs may reduce the rate of acute myocardial infarction. However, ACEIs or ARBs may increase cardiac output perioperatively. Due to the low and very low methodology quality, high risk of bias, and lack of power of the included studies, the true effect may be substantially different from the observed estimates. Perioperative (mainly elective cardiac surgery, according to included studies) initiation of ACEIs or ARBs therapy should be individualized.

Abstract
PURPOSE OF REVIEW Populations across the world are getting older and requiring more surgery. Elderly patients present unique challenges to the anesthesiologist and anesthesia-care team. This review addresses some concerns when caring for an elderly patient. Specifically, we discuss postoperative cognitive decline (POCD) and postoperative delirium, perioperative beta-blockade and use of newer drugs, as well as older drugs. RECENT FINDINGS POCD has emerged as a new concern for anesthesiologists and their older patients. Several recent studies indicate that POCD is common after noncardiac surgery, with an incidence approaching 30-40% at discharge, although this incidence declines at 3 months. Some data suggest that POCD imparts risk for death. However, there is conflicting evidence. With regard to beta-blocker therapy, there has been growing concern about widespread use of beta-blocker therapy in the perioperative period, especially because such therapy might increase the risk for stroke. SUMMARY Elderly patients require focused diligent care. They are particularly sensitive to the many drugs that are administered in the perioperative period. Recent data suggest that POCD is a real concern, but it is unclear what, if anything, can be done to prevent this complication. Beta-blocker therapy is beneficial in select patients but its widespread use cannot be supported.

Abstract
Owing to modern epidemiology in Western countries, ageing represents a growing health burden. In general, because of age itself and comorbid conditions, all clinical cardiovascular manifestations have a higher mortality rate and a worse outcome in older people compared with in younger individuals. Diagnosis of the disease in the elderly in an emergency setting is particularly challenging for the practitioner. Age-related cardiovascular changes and comorbid conditions may alter signs, symptoms and adaptation to the disease and response to treatment. Bedside Doppler echocardiography is likely to play a major role in guiding diagnosis, therapeutic strategies and prognosis. The purpose of this review is to appraise the application of echocardiographic examination in helping the clinician facing emergency situations that involve the cardiovascular system in the older population.

Abstract
Background Infection in severe pressure ulcers can lead to sepsis with a 6-month mortality as high as 68%. Methods Operative records of 142 consecutive operative debridements on 60 patients in a dedicated wound healing inpatient unit were reviewed, from the Wound Electronic Medical Record, for identification of key steps in debridement technique, mortality, unexpected returns, and time to discharge following debridement. Results The mean age of the patients was 73.1 years, and 45% were men. Most wounds (53%) were located on the hip (ischial or trochanteric); others were on the sacrum (32%) and the heels (14%). The mean initial wound area prior to debridement was 14.0 cm2, and 83% of debridements were performed on stage IV pressure ulcers. The postoperative hospital stay averaged 4.1 days. Key steps in the technique included (1) exposure of areas of undermining by excising overlying tissue; (2) removal of callus from wound edges; (3) removal of all grossly infected tissue; and (4) obtaining a biopsy of the deep tissue after debridement of all nonviable or infected tissue for culture and pathology to determine the presence of infection, fibrosis, and granulation tissue. There was one death 9 days post-debridement of a sacral ulcer and one unplanned return to the operating room for bleeding 8 days post-debridement. Conclusions Operative debridement of pressure ulcers is safe, despite the medical co-morbidities in patients with severe pressure ulcers. Proper debridement technique may prevent sepsis and death in patients with multiple co-morbid conditions.

Abstract
PURPOSE OF REVIEW Pneumonectomy has the highest perioperative risk among common pulmonary resections. The purpose of this review is to update clinicians on the importance of anesthetic management for these patients. RECENT FINDINGS Two complications associated with increased perioperative mortality are relevant to anesthetic management: postoperative arrhythmias and acute lung injury. The geriatric population is particularly at risk for arrhythmias. Adequate preoperative cardiac assessment and drug prophylaxis may decrease this risk. Patients with decreased respiratory function are at increased risk for acute lung injury. The use of large tidal-volume ventilation during anesthesia may increase this risk. There is a trend to better outcomes in centers with larger surgical volumes. SUMMARY Patients should have a preoperative assessment of their respiratory function in three areas: lung mechanical function, pulmonary parenchymal function and cardiopulmonary reserve. Interventions that have been shown to decrease the incidence of respiratory complications include cessation of smoking, physiotherapy and thoracic epidural analgesia. Extrapleural pneumonectomy and sleeve pneumonectomy are surgical variations that place specific increased demands on the anesthesiologist. The rare but treatable complication of cardiac herniation must always be remembered as a potential cause of life-threatening hemodynamic instability in the early postoperative period.

Abstract
PURPOSE OF REVIEW To consider optimal analgesic strategies for thoracic surgical patients. RECENT FINDINGS Recent studies have consistently suggested analgesic equivalence between paravertebral and thoracic epidural analgesia. Complications appear to be significantly less common with paravertebral analgesia. SUMMARY There is good evidence that paravertebral block can provide acceptable pain relief compared with thoracic epidural analgesia for thoracotomy. Important side-effects such as hypotension, urinary retention, nausea, and vomiting appear to be less frequent with paravertebral block than with thoracic epidural analgesia. Paravertebral block is associated with better pulmonary function and fewer pulmonary complications than thoracic epidural analgesia. Importantly, contraindications to thoracic epidural analgesia do not preclude paravertebral block, which can also be safely performed in anesthetized patients without an apparent increased risk of neurological injury. The place of paravertebral block in video-assisted thoracoscopic surgery is less clear.

Abstract
BACKGROUND We have previously reported that landiolol, an ultra-short-acting beta1-adrenoceptor antagonist, does not alter the anaesthetic effects of isoflurane. Here, we investigated the influence of propranolol on the electroencephalographic (EEG) effects and minimum alveolar concentration (MAC) of isoflurane. METHODS Fourteen swine [25.0 (SD 4.0) kg] were anaesthetized by isoflurane inhalation. The inhalation concentration was decreased to 0.5% and maintained for 25 min, before being returned to 2%, and maintained for a further 25 min. End-tidal isoflurane concentrations and spectral edge frequencies were recorded. Pharmacodynamic analysis was performed using a sigmoidal inhibitory maximal effect model for spectral edge frequency vs effect-site concentration. After measurement of the EEG effect, MAC was determined using the dew-claw clamp technique, in which movement in response to clamping is recorded. After completion of control measurements, a propranolol 4 mg bolus followed by an infusion (2 mg h(-1)) was started. After a 30 min stabilization period, the inhalation concentration of isoflurane was varied as in the control period and MAC was re-assessed. RESULTS Propranolol shifted the concentration-effect relationship to the left and decreased the effect-site concentration that produced 50% of the maximal effect from 1.30 (0.18) to 1.13 (0.17)%. Propranolol also decreased isoflurane MAC from 1.91 (0.35) to 1.54 (0.32)%. CONCLUSIONS Propranolol alters both the hypnotic and anti-nociceptive effects of isoflurane. In contrast to landiolol, lipophilic beta-adrenoceptor antagonists may increase the potency of inhalational anaesthetics.

Abstract
The management of hypertension continues to pose important challenges. Recent developments have established the importance of more rigorous blood pressure control in the community. In the perioperative setting, hypertension has long been recognised as undesirable, although the adverse impact of high blood pressure on the acute risks of elective surgery may have been previously overstated.A number of agents and techniques are available to control blood pressure perioperatively. These include principally general and regional anaesthetics, alpha(2)-adrenoceptor agonists, peripheral alpha(1)- and beta-adrenoceptor antagonists, dihydropyridine calcium channel antagonists, dopamine D(1A)-receptor agonists (fenoldopam), and nitric oxide donors. Recent years have seen important developments in the receptor selectivity of new compounds and in pharmacokinetics, particularly esterase metabolism. The future study of genomics may enable us to identify patients at risk for hypertension-related adverse events and target therapies most effectively to these high-risk groups.

Abstract
Patients undergoing non-cardiac vascular surgery have arterial disease affecting more than one vascular bed and commonly have multiple significant co-morbidities. The surgical and anaesthetic teams are asked to address pre-, peri- and postoperative management issues relating not only to the surgery but arising from these co-morbidities. Here we review the strategies and rationale for the optimisation of these high risk patients.
