Association Between Sarcopenia and Acupressure Testing in Older Adults Requiring Long-Term Care

Background and Objectives: This study analyzed the relationship between pressure pain test outcomes and sarcopenia in elderly patients and explored possible clinical applications. Materials and Methods: The participants included 143 older adults requiring long-term care who could be diagnosed with sarcopenia. Along with sarcopenia diagnosis, the participants underwent acupressure testing symmetrically at nine sites (occiput, lower cervical, trapezius, supraspinatus, second rib, lateral epicondyle, gluteus, greater trochanter, and knee), totaling 18 sites. The analyses included comparisons of sarcopenia status and total tender points between the groups and a multivariable analysis. The association between sarcopenia and the number of tender points were examined based on correlations between the number of tender points and grip strength, walking speed, and skeletal muscle mass index (SMI). Intergroup comparisons and multivariable analysis of tender points with and without sarcopenia were performed to investigate specific tender points associated with sarcopenia. Results: An independent association was observed between sarcopenia and the number of tender points (p = 0.001). Furthermore, the number of tender points was correlated with grip strength (ρ = −0.536, p < 0.001), walking speed (ρ = −0.200, p = 0.028), and SMI (ρ = −0.394, p < 0.001). The supraspinatus (p = 0.029, 95% confidence interval: 1.221–35.573) and lower cervical (p = 0.039, 95% confidence interval: 1.050–7.245) regions were identified as specific tender points. Conclusions: In older adult patients requiring long-term care, sarcopenia is associated with an increased number of tender points throughout the body, with the supraspinatus and lower cervical regions potentially being specific tender points. Acupressure testing for tenderness may be a useful assessment parameter in sarcopenia patients.

QLTI-03. REAL-WORLD PARADIGM FOR TREATMENT OF PRIMARY CNS LYMPHOMA PATIENTS IN CLINICAL PRACTICE

Abstract Although high-dose methotrexate (HD-MTX) is the foundation of induction therapy for primary CNS lymphoma (PCNSL), a gold-standard regimen has yet to be established. A 10-case-based survey, to assess the practice patterns at key decision-points in adult PCNSL management outside of clinical trials, was distributed through IPCG, HOVON, and AAN Neuro-Oncology Section. Eighty-five responses were collected from North American (N=42), European (N=33), Asian (N=7), and other countries (N=3) from neurologist neurooncologists (N=35), hem-onc neurooncologists (N=24), hematologist-oncologists (N=18), neurosurgeons (N=5), radiation-oncologist (N=2), and hematopathologist (N=1). The most common first-line induction regimen was R-MP+/-V: rituximab, HD-MTX, procarbazine, +/-vincristine (N=28) followed by MATRix: HD-MTX, cytarabine, thiotepa, rituximab (N=23), then R-MT: rituximab, HD-MTX, temozolomide (N=19). For elderly patients, R-MP+/-V remained most common (N=32). The majority preferred to omit intra-CSF chemotherapy (N=50). The most preferred consolidation after complete response was high-dose chemotherapy and autologous stem-cell transplantation (HDC-ASCT, N=57), or high-dose cytarabine (N=17) in elderly patients. In cases of partial response, the most common approach was still HDC-ASCT (N=24). For stable disease, participants would move to various salvage chemotherapy (N=33), continue additional induction (N=39), or to move to radiotherapy (N=10). If early progression was noted, the most preferred approach was non-methotrexate chemotherapy (N=31). For recurrences after previous complete response and HDC-ASCT consolidation, the majority preferred to try chemotherapy before moving to radiotherapy in scenarios < 1 year (N=64) or > 1 year from consolidation (N=68), and even if the performance status was poor (N=57). Close to half (N=34) participants felt there is a role for stereotactic radiosurgery in various clinical settings. This survey noted clear consensus to use multi-drug MD-MTX based chemotherapy, and common induction regimens, however, highlighted a great variety of treatment preferences after first-line therapy even amongst disease experts through clinical consortiums, suggesting likely wider range of treatments and disease response in larger community settings.

NCOG-50. LONG TERM-SURVIVAL OF AN ELDERLY PATIENT WITH GIANT CELL CEREBELLUM GLIOBLASTOMA (GBM)

Abstract INTRODUCTION Primary cerebellar glioblastoma (GBM) in adult is very rare and accounts for 1% of all GBM. Giant cell variant cerebellar GBM is even rarer. Because of the rarity, its molecular feature, the response to the standard treatment, and biological behavior of tumor progression are not well understood. CASE REPORT An 80 yo male presented with headache, nausea, vomiting and ataxia in 2019. Brain MRI was notable for a large enhancing cerebellar mass. Surgical resection was completed, and pathology was giant cell GBM. Molecular studies showed IDH-wildtype, CDKN2A/B copy number loss, positive TP53 G262V mutation as well as KIT and KDR amplification. The patient underwent standard 6-week concomitant temozolomide (TMZ) and radiation therapy. He only completed 3 cycles of low dose adjuvant temozolomide and two cycles of lomustine due to intolerance of both chemotherapy agents. After that the patient has been off treatment and received brain MRI surveillance over past 4 years. Two years later, his brain MRI showed new punctuate lesions in the radiation field. Suspecting the radiation necrosis; the patient underwent observation. Later, more nodular enhancing lesions developed at the outside region of the radiation field. Tumor progression was considered but the patient wished no biopsy or re-radiation. The new small nodular lesions on MRIs over past two years have behaved unusually with small fluctuations among mild progression, stabilization, or regression. His physical functions have been preserved with a Karnofsky Performance Status scale of 90% with normal cognition. DISCUSSION The patient, who is now 85 years old, has surpassed a 4.5-year survival mark, which is remarkable compared to the supratentorial and the cerebellar GBM with a few months’ survival mark in elderly patients. Our experience emphasizes the different behavior (good response) of a very rare giant cell cerebellar GBM to the standard treatment for newly diagnosed GBM.

A PATIENT WITH OSTEOARTHRITIS AND HYPERTENSION IN GENERAL MEDICAL PRACTICE

Osteoarthritis is one of the most common diseases in Ukraine and worldwide, often leading to early disability in people of working age, making it both a medical and social concern. According to the European Society for Clinical and Economic Aspects of Osteoporosis, Osteoarthritis, and Musculoskeletal Diseases, as well as the International Society for the Study of Osteoarthritis, it is known that a middle-aged patient with osteoarthritis typically has four accompanying pathologies. In elderly patients, in addition to osteoarthritis, up to eight other chronic conditions are often diagnosed. Comorbidity is frequently observed in middle-aged patients with osteoarthritis. Understanding the pathogenetic links between osteoarthritis and comorbid conditions plays an important role in the timely diagnosis and treatment of these diseases, helping to maintain a high quality of life for patients. Objevtive: the study of the pathogenesis of osteoarthritis and arterial hypertension, along with the proposed therapy for treating comorbidities in patients with both osteoarthritis and arterial hypertension, aims to enhance the treatment outcomes. Materials and methods. Analytical and bibliosemantic methods were used in this study. During the scientific search, 38 modern literature sources were reviewed and analyzed concerning the pathogenetic impact on the development of osteoarthritis and arterial hypertension, as well as their shared mechanisms in the development and progression of both conditions. The study was carried out at the Department of Family Medicine and Therapy of the Regional Rheumatology Center, M. V. Sklifosovsky Poltava Regional Hospital. A total of 50 people were examined; the main group consisted of 35 individuals with stage II hypertension, grade 2, combined with stage II knee osteoarthritis (according to the Kellgren-Lawrence scale), with joint dysfunction of stages 1-2. These patients were aged 40-65 years (mean age 51.8±2.14 years). The duration of hypertension was 10.07±1.24 years, and the duration of manifested osteoarthritis was 8.56±1.03 years. The comparison group consisted of 20 individuals with stage II, grade 2 hypertension (mean age 52.5±2.38 years), with a mean hypertension duration of 11.31±1.17 years. The clinical diagnosis of osteoarthritis was established according to the recommendations of the European Alliance of Associations for Rheumatology (2018). The diagnoses of comorbid conditions were confirmed in accordance with relevant orders from the Ministry of Health of Ukraine, with verification by specialized experts. Patients with osteoarthritis received standard treatment, and, when necessary, additional treatment for comorbid conditions was prescribed (a hypotensive combination of an ACE inhibitor and long-acting calcium. Results: The presence of osteoarthritis exerts an additional negative impact on heart rate variability in patients with hypertension. The reduction of the Low Frequency/High Frequency (LF/HF) index due to the use of this therapy (a combination of an ACE inhibitor and a long-acting calcium antagonist in doses of 4/5 mg, 4/10 mg, 8/5 mg, 8/10 mg) in the treatment of patients with comorbidity of hypertension and osteoarthritis contributes to the activation of the sympathetic nervous system, reduction of patient mortality, balancing of the nervous system by inhibiting sympathetic nervous tone, and lowering high blood pressure. Conclusions: The proposed combination therapy for patients with osteoarthritis and hypertension contributes to prolong remission of both the primary disease and comorbid conditions, reduces the frequency of hospitalizations, and shortens inpatient treatment by 3-4 days.

Comprehensive geriatric assessment for predicting postoperative delirium in oral and maxillofacial surgery: a prospective cohort study.

Identifying high-risk patients for developing postoperative delirium (POD) is essential for optimizing the medical field's human and financial resources through specialty-relevant geriatric assessments that can aid in establishing prehabilitation strategies. This study aims to identify geriatric screening tools to predict preoperative delirium and explore the high-risk elderly patients undergoing oral maxillofacial surgery. A comprehensive geriatric assessment encompassing 23 instruments was used to evaluate inpatients undergoing surgery under general anaesthesia, preoperatively and postoperatively. Selective intraoperative and postoperative variables were also assessed for their relation to POD occurrence. This prospective study included 90 patients (mean age 79.0 years) from August 2022 to August 2023. The POD rate in this cohort was (8.9% n = 8). The Clock-Drawing Test (CDT) was significantly associated with POD occurrence (p = 0.005). Significant associations were found between POD occurrence and operation type (p = 0.018), duration (p = 0.026), length of stay ( p = 0.002), and postoperative hemoglobin levels (p = 0.027). This study highlights the importance of comprehensive geriatric assessments in predicting POD in elderly patients. Future research should build on these findings to enhance preoperative care strategies and improve outcomes.Trial registration: German Register of Clinical Studies, DRKSID DRKS00028614.

CYSTATIN C AS A MARKER OF EARLY KIDNEY DAMAGE UNDER ARTERIAL HYPERTENSION (LITERATURE REVIEW)

The purpose of this study is to determine kidney functional activity in relation to cystatin C levels, as reported in recent literature. Materials and Methods. A bibliographic-semantic method was employed to assess the current state of research on this topic, analyzing findings from previous scientific studies using both literature sources and electronic resources. Results. Chronic kidney disease (CKD) is as prevalent as hypertension. It is well-known that arterial hypertension exacerbates kidney function, making the assessment of renal functional activity critical. Glomerular filtration rate (GFR) is commonly used to evaluate kidney function, relying on established indicators as well as newer, more objective markers. Among these, cystatin C has emerged as one of the most accurate and sensitive indicators for assessing kidney function. Its concentration in serum negatively correlates with GFR and is particularly valuable for detecting renal pathology even when creatinine levels remain unchanged. This insight has led to the development of an estimated GFR (eGFR) formula that incorporates cystatin C levels. Research suggests that cystatin C levels increase with hypertension, although studies on the specific relationship between cystatin C and hypertension remain limited. Some findings propose that serum cystatin C could serve as a predictor of disease severity, particularly in elderly hypertensive patients with coronary heart disease. The literature supports the utility of cystatin C as a reliable marker for assessing GFR, which facilitates early detection of CKD even when albumin excretion is normal, thus identifying kidney damage at an early stage. Ppotential mechanisms by which elevated cystatin C may contribute to cardiovascular damage are under investigation. As a highly informative endogenous marker of GFR, serum cystatin C not only aids in staging CKD but is especially valuable in identifying early renal dysfunction. Conclusion. The measurement of cystatin C enables a highly accurate assessment of kidney function and aids in evaluating cardiovascular risk, especially when hypertension coexists with chronic kidney disease. Further research is needed to improve predictions of chronic kidney progression at various stages and in the presence of comorbidities. Such insights will support more effective preventive strategies to slow the progression of this pathology.

Tolerability of perioperative chemotherapy for gastric cancer in real clinical practice

Background. The choice of the optimal scheme of perioperative chemotherapy of locally advanced gastric cancer is an urgent problem in real clinical practice. Aim. To analyze therapy tolerability in this cohort of patients. Materials and methods. Perioperative chemotherapy of gastric cancer was performed in 90 patients in the Chemotherapy Department of the Oncology Center №1 of the Yudin City Clinical Hospital from January 2021 to February 2024. Results. The incidence of severe complications at the preoperative stage was 41.9% for the FOLFOX regimen and 40.7% for the FLOT regimen, at the adjuvant stage – 17.4 and 43.2%, respectively. Operative treatment was successfully performed in 79 (87.8%) patients, and the full scope of combined treatment of locally advanced gastric cancer was completed in 59 (65%) patients. 80.8% of pathomorphologic responses in the FOLFOX group and 67.9% in the FLOT group were TRG3-4, with complete response noted in only one patient. Conclusion. High toxicity rates in elderly and comorbid patients on the FOLFOX regimen require the development of an individualized approach to the treatment of this group of patients.

Colorectal carcinoma-induced iron deficiency anemia: A literature review and a case scenario

Colorectal carcinoma (CRC) is among the leading cancers worldwide and a major cause of cancer-related mortality. Iron deficiency anemia (IDA), resulting from inadequate iron for hemoglobin production, has been increasingly linked to CRC, often leading to misdiagnosis. This study reviews the clinicopathological associations of IDA in the context of colorectal cancer, using the medical records of a septuagenarian diagnosed with both conditions as a case study. Employing the Problem-Intervention-Comparison-Outcome model, we searched for “colorectal carcinoma” and “iron deficiency anemia” as keywords. CRC ranks among the top five cancers of global health importance, with socioeconomic factors, sedentary lifestyles, and dietary choices significantly influencing both conditions. Notably, IDA is particularly associated with the right-sided CRC in individuals over 40. Upregulation of interleukin-6 in CRC cells stimulates hepcidin release, which mediates anemia of chronic disorders and IDA. The case revealed right-sided signet ring cell CRC, microcytic hypochromic anemia, bone marrow metastasis, and low serum iron and ferritin levels. This study highlights the need for increased suspicion of CRC in middle-aged and elderly patients presenting with recurrent IDA. Regular screening is essential for the early detection and improved treatment outcomes. While colonoscopy is the gold standard for prevention, its effectiveness in detecting early molecular links between neoplasia and chronic inflammation is limited. There is also no consensus on surveillance protocols, and many gastroenterologists do not adhere to recommended biopsy sampling practices. In conclusion, this study advocates for including complete blood count and iron studies as essential tests in guidelines for screening and diagnosis for CRC-related IDA to enhance diagnostic practices.

Prognostic impact of a 3-week multimodal prehabilitation program on frail elderly patients undergoing elective gastric cancer surgery: a randomized trial.

Research indicates that prehabilitation is effective in optimizing physical status before surgery, although this method may be considered "aggressive" for frail elderly patients. This study aimed to evaluate whether multimodal prehabilitation decreases postoperative complications and improves functional recovery in frail elderly patients undergoing gastric cancer surgery, in comparison to usual clinical care. This study was a single-center, single-blind, randomized controlled trial. Patients over 65 years old with a Fried Frailty Index of 2 or higher, scheduled for gastric cancer surgery, were considered for inclusion. Eligible participants were randomized in a 1:1 ratio to either the intervention or control group. The intervention group underwent a 3-week multimodal prehabilitation program prior to surgery, in addition to perioperative care guided by ERAS protocols. The control group received only the latter. The primary outcome was the comprehensive complications index (CCI) measured at 30 days after surgery. Secondary outcomes included 30-day overall complications, functional walking capacity as assessed by 6-minute walking distance (6MWD) at 4 weeks postoperatively, and 3-month postoperative quality of life. This study was registered at ClinicalTrials.gov (No. NCT06510088). Among the 112 eligible patients, the median age was 74 years, with 58 (52.7%) being female.No between-group difference was found in the primary outcome measure, 30-day CCI. The Median (Q1-Q3) CCI for the intervention and control groups was 0 (0-12.2) and 0 (0-22.6) (P = 0.082), while the mean (SD) CCI was 6.1 (15.8) and 9.8 (12.7), respectively (P = 0.291). Notably, the incidence of severe complications (CCI > 20) was significantly lower in the intervention group compared to the control group (11.1% vs. 25.9%, P = 0.046), particularly in terms of medical complications (12.3% vs. 29.3%, P = 0.025). Preoperatively, 27 patients (47.4%) in the intervention group exhibited an increase in the 6MWD of at least 20m, compared to 16 patients (27.6%) in the control group (P = 0.028). At 4 weeks postoperatively, more patients in the intervention group returned to their baseline 6MWD levels (63.2% vs. 43.1%, P = 0.031). Secondary parameters of functional capacity in the postoperative period generally favored the multimodal prehabilitation approach. In frail elderly patients undergoing elective gastric cancer surgery, a prehabilitation program did not affect the 30-day postoperative complication rate or CCI but reduced severe complications and improved perioperative functional capacity.

Advances in CAR NK Cell Therapy for Targeting and Eradicating Circulating Tumor Cells: Challenges and Solutions for Aging Patients Mini Review

Chimeric Antigen Receptor (CAR) Natural Killer (NK) cells represent a promising advancement in cancer immunotherapy, particularly for targeting circulating tumor cells (CTCs) and preventing metastasis. This review examines the latest developments in CAR NK cell therapy, including diverse NK cell sources, genetic engineering techniques, and dual mechanisms of action. Targeting CTCs with CAR NK cells shows significant potential in aggressive cancers like triple-negative breast cancer (TNBC) and pancreatic cancer. The impact of aging on NK cell function, especially regarding cytotoxicity, cytokine secretion, and persistence, poses challenges for elderly patients, but strategies such as interleukin-15 and metabolic interventions offer potential solutions. The review also addresses current limitations, such as poor persistence in immunosuppressive microenvironments and low solid tumor infiltration, while proposing combination therapies to enhance effectiveness. Although still in earlier clinical stages compared to CAR T cells, CAR NK cells’ safety profile and MHC-independent recognition mechanisms make them a versatile therapeutic option. Future directions include optimizing NK cell persistence, improving infiltration, and developing age-adapted therapies for elderly patients. _________________________________________________________________________________________ Keywords: CAR NK cells, CAR T cells, Circulating tumor cells (CTCs), Cell Therapy, Aging

The Role of Omega-3 Fatty Acid Supplementation in Slowing Cognitive Decline Among Elderly Patients With Alzheimer's Disease: A Systematic Review of Randomized Controlled Trials

Safety and feasibility of robotic surgery in geriatric patients with rectal cancer.

The incidence of rectal cancer is increasing in the elderly population, yet the safety of surgical interventions in this group, particularly robotic surgery, is still debated. This study aims to investigate the safety and short-term postoperative outcomes of robotic surgery in geriatric patients (aged ≥ 70years) with rectal cancer. Patients diagnosed with rectal cancer and undergoing robotic surgery between March 2021 and September 2023 were divided into two groups based on age: the elderly group (aged ≥ 70years) and the younger group (aged < 70years), totaling 108 patients. The study included 80 younger patients in group 1 and 28 elderly patients in group 2. The groups had similar gender distribution and tumor characteristics. The elderly group had higher ASA scores and lower albumin levels and underwent the Miles procedure more frequently. The stoma rate was higher in the elderly group. Operation duration, tumor diameter, lymph node dissection numbers, pathological stage, and other histopathological features were similar in the two groups. Postoperative outcomes like hospital stay, complication rates, anastomotic leakage, reoperation rates, unplanned readmissions, and mortality were comparable between the groups. Robotic surgery for rectal cancer in elderly patients is technically feasible and safe. Age should not be a determining factor in patient selection for robotic surgery or be considered a risk factor for postoperative complications.

BackgroundBendamustine–rituximab (BR) therapy stands out as a promising alternative for elderly patients with diffuse large B-cell lymphoma (DLBCL), demonstrating notable efficacy when conventional regimens pose challenges. Despite its clinical success,...

Hypernatremia is associated with mortality in severe elderly sepsis patients.

To explore the relationship between hypernatremia and 28-day mortality in elderly sepsis patients. A total of 179 elderly patients (age ≥65 years) with elevated serum sodium admitted to the Department of Critical Care Medicine of Nanjing Hospital affiliated with Nanjing Medical University from September 2021 to September 2022 were included in this retrospective observational study. The clinical data of all patients were collected, and the patients were divided into septic group and nonseptic groups according to the Sepsis 3.0 definition. The clinical features, acute physiological and chronic health II score (APACHE II score), mechanical ventilation time, serum sodium value and duration of serum sodium elevation were compared between the two groups. ROC curves were drawn to evaluate the predictive value of each index on the prognosis of sepsis patients, and Kaplan‒Meier survival analysis was carried out on patients with different serum sodium peaks. (1) The changes in serum sodium within 48 hours after admission in the sepsis group were small and statistically significant compared with those in the nonsepsis group (P = 0.039); however, the serum sodium elevation duration was longer (P = 0.018). (2) Compared with nonseptic patients, the 7-day mortality of septic patients was higher (15.8 vs. 7.7, P<0.001). The 28-day mortality of septic patients was higher than that of nonseptic patients, but there was no significant difference between the two groups (P = 0.086). (3) The serum sodium level in the sepsis group was higher than that in the nonsepsis group on the 1st, 3rd, 5th and 7th days (P<0.001). There was no significant difference in mechanical ventilation time or duration of stay in the ICU between the two groups. (4) The ROC curve analysis showed that the peak value of serum sodium had predictive value for the prognosis severity of elderly patients with sepsis. The area under the curve (AUC) was 0.753, the 95% confidence interval (95% CI) was 0.639~0.867, and the best cut-off value was 154.9 mmol/L. (5) According to the best cut-off value of the serum sodium peak, the septic patients were divided into two groups: the peak value of serum sodium was ≥154.9 mmol/L (group A), and the peak value of serum sodium was <154.9 mmol/L (group B). Among them, the case fatality rate was higher at 7 days and 28 days when the peak value of serum sodium was ≥154.9 mmol/L (group A) (22.0% vs. 8.6%); the χ2 value was 35.379, P<0.05; 75.6% vs. 37.1%, χ2 = 14.21, P = 0.003). There was no significant difference in mechanical ventilation time or duration of stay in the ICU between the two groups. (6) Kaplan‒Meier survival analysis showed that the median survival time of patients with a serum sodium peak ≥154.9 mmol/L (group A) was significantly shorter than that of patients with a serum sodium peak < 154.9 mmol/L (group B) (16.7±1.4 d vs. 24.8±1.2 d, P <0.05). The serum sodium increase in elderly sepsis patients lasts for a long time, and the serum sodium fluctuation is relatively small. The serum sodium peak value has predictive value for 28-day mortality.

Averaged Oxygen Desaturation Improves the Prognostic Value of the Six-Minute Walk Test in Elderly Patients with Heart Failure.

Heart failure (HF) is a major cause of hospitalization, and exercise capacity is a key prognostic marker. The six-minute walk test (6MWT) is widely used to assess exercise capacity, but six-minute walk distance (6MWD) varies among individuals, especially the elderly. This study aimed to assess the hypothesis that ΔSpO₂-Ex, the average oxygen desaturation during the 6MWT, could enhance the prognostic value of 6MWD in elderly HF patients for cardiovascular risk prediction. In this single-center, prospective observational study, 55 patients aged ≥ 65 years with acute HF were evaluated before discharge. Patients were divided into small and large ΔSpO₂-Ex groups and short and long 6MWD groups based on cut-off values of 6.7% and 220 m, respectively, obtained from the Receiver Operating Characteristics curve analysis. Patients were followed for one year to assess major adverse cardiovascular events, including rehospitalization for heart failure or cardiovascular death. The mean ΔSpO₂-Ex was 5.8 ± 4.3%, and the mean 6MWD was 237.5 ± 106.7 m. Patients with large ΔSpO₂-Ex had significantly higher event rates (HR 6.66, p < 0.001), while those with short 6MWD had HR of 2.40 (p = 0.03). Combining ΔSpO₂-Ex with 6MWD improved predictive accuracy (AUC 0.78) compared to either marker alone (AUC 0.72 for ΔSpO₂-Ex and 0.62 for 6MWD). Importantly, patients with both large ΔSpO₂-Ex and short 6MWD had the highest event rates, indicating the additive prognostic value of combining both markers. ΔSpO₂-Ex is a complementary marker to 6MWD, improving risk stratification in elderly HF patients.

Effects of combined anesthesia on pulmonary oxygenation function, hemodynamics, and respiratory compliance in elderly patients undergoing pulmonary lobectomy for lung cancer.

Traditional general anesthesia in elderly lung cancer patients undergoing pulmonary lobectomy may lead to hemodynamic fluctuations and postoperative complications. To optimize anesthesia efficacy, this study explores the application of combined anesthesia (general anesthesia combined with thoracic paravertebral block) in such surgeries. We evaluated the improvement of pulmonary oxygenation function, hemodynamic stability, and respiratory compliance in elderly lung cancer patients undergoing pulmonary lobectomy with combined anesthesia. This retrospective study analyzed 100 elderly lung cancer patients who underwent pulmonary lobectomy at our hospital from February 2020 to December 2023. Patients were divided into 2 groups: the control group received general anesthesia, while the treatment group received combined anesthesia (general anesthesia plus thoracic paravertebral block). By comparing intraoperative hemodynamic parameters, postoperative pulmonary oxygenation function, respiratory compliance, cognitive function, sleep quality, and postoperative complication rates between the 2 groups, we assessed the application efficacy of combined anesthesia. Compared to the control group, the treatment group exhibited better hemodynamic stability intraoperatively, significantly improved postoperative pulmonary oxygenation function and respiratory compliance. Additionally, patients in the treatment group showed faster recovery of cognitive function, better sleep quality, and a relatively lower incidence of postoperative complications. Combined anesthesia demonstrates unique advantages in pulmonary lobectomy for elderly lung cancer patients, optimizing intraoperative hemodynamic stability, promoting postoperative pulmonary function recovery, accelerating cognitive function recovery, improving sleep quality, and potentially reducing the risk of postoperative complications. This finding provides a new effective strategy for anesthesia management in elderly lung cancer patients.

Relationship of Serum Fibroblast Growth Factor 23, Hypoxia-Inducible Factor-1α, and Klotho with In-Stent Restenosis in Elderly Patients with Coronary Artery Disease after the Treatment of Percutaneous Coronary Intervention.

In-stent restenosis (ISR) commonly occurs in elderly patients with coronary artery disease (CAD) after percutaneous coronary intervention. Atherosclerosis in elderly patients may be the leading cause of ISR. Therefore, we aim to explore the relationship between vascular calcification-associated factors and ISR occurrence. Elderly patients were enrolled according to standard inclusion and exclusion criteria. The serum fibroblast growth factor 23 (FGF23), hypoxia-inducible factor-1α (HIF-1α), and Klotho levels were determined using an enzyme-linked immunosorbent assay. The degree of coronary artery stenosis of the patients with CAD before operation was assessed using the Gensini score. The correlation was analyzed using Pearson analysis. The prediction value was evaluated using receiver operating characteristic (ROC) curve analysis. The patients with CAD were classified into the ISR group with 97 cases and the non-ISR (NISR) group with 349 cases. The Gensini score, serum FGF23, and HIF-1α levels increased while Klotho levels decreased in patients with CAD of the ISR group compared with those of the NISR group. Pearson analysis showed that FGF23 and HIF-1α positively correlated while Klotho negatively correlated to the Gensini score. ROC analysis showed all three factors could effectively predict the occurrence of ISR. Furthermore, the joint had a more effective prediction value for ISR occurrence. The dynamic analysis presented that the serum FGF23 and HIF-1α levels dramatically increased while Klotho levels decreased in patients with CAD after 1-year follow-up. Serum FGF23 and HIF-1α positively correlated while serum Klotho negatively correlated to ISR. Conclusively, these three factors effectively predicted the occurrence of ISR.

Clinical characteristics and bloodstream infection pathogens by gram-negative bacteria in different aged adults: A retrospective study.

This study aims to determine the characteristics and distribution of pathogenic bacteria in bloodstream infections (BSIs) by gram-negative bacteria in adults. One hundred seventy-one adult patients with BSIs who were treated at the Affiliated Hospital of Chengde Medical College between January 2018 and January 2020 were included in this study. The patients were assigned to the young- and middle-aged group and elderly group based on age. General patient data were analyzed. More elderly patients had BSIs and gram-negative bacteria than young- and middle-aged patients. The incidence of underlying diseases in elderly patients was significantly higher than the young- and middle-aged patients (P < .01). The composition of Brucella spp. was significantly different between the elderly group and young- and middle-aged group (P < .05). There were significantly more gallbladder infections in the elderly group than the young- and middle-aged group, and significantly fewer elderly patients had no definite infection sites than the young- and middle-aged group (P < .05). The incidence of complications and in-hospital mortality in the elderly group was higher than the young- and middle-aged group (P < .05). BSIs caused by gram-negative bacteria mainly involved elderly patients. BSIs were characterized by complications and a poor prognosis, as well as pathogenic bacteria and primary infection sites.

Nephroprotective effect of SGLT2 inhibitors in elderly patients with type 2 diabetes mellitus and hypertension: a real-world population-based cohort study

ABSTRACT Objectives This study aimed to investigate the nephroprotective effect of sodium-glucose cotransporter 2 inhibitors (SGLT2i) in elderly patients with type 2 diabetes mellitus (T2DM) and hypertension based on real-world clinical data. The study aimed to provide a theoretical basis for evidence-based pharmacological treatment of chronic kidney disease in this population. Methods The ‘Health Cloud’ platform of the Shanghai Municipal Health Commission was employed to identify and screen elderly patients with T2DM and hypertension. The propensity score matching cohort was further constructed to estimate the effect of SGLT2i on the risk of rapid decline in renal function (∆eGFR≤-5 ml/min/1.73 m2 or ∆eGFR%≤-5%). Multiple sensitivity analyses were conducted to assess the robustness of the results. Results After propensity score matching, no significant differences of covariates were identified between the SGLT2i and non-SGLT2i groups. The results of multivariate logistic models demonstrated a consistent and inverse correlation between SGLT2i use and the risk of rapid eGFR decline, whether defined as ∆eGFR≤-5 ml/min/1.73 m2 (OR = 0.60, 95% CI:0.38-0.96) or ∆eGFR%≤-5%（OR = 0.57, 95% CI:0.37-0.89). In the stratification of renin-angiotensin system inhibitor (RASi) treatment, SGLT2i was associated with a lower risk of rapid eGFR decline in the RASi group (all ORs < 1, p < 0.05), with no interaction between SGLT2i and RASi (all P for interaction > 0.05) detected. Conclusions SGLT2i significantly reduced the risk of rapid eGFR decline in elderly patients with T2DM and hypertension, but the synergistic effect with RASi remains unclear.

Prediction of vancomycin plasma concentration in elderly patients based on multi-algorithm mining combined with population pharmacokinetics

The pharmacokinetics of vancomycin exhibit significant inter-individual variability, particularly among elderly patients. This study aims to develop a predictive model that integrates machine learning with population pharmacokinetics (popPK) to facilitate personalized medication management for this demographic. A retrospective analysis incorporating 33 features, including popPK parameters such as clearance and volume of distribution. A combination of multiple algorithms and Shapley Additive Explanations was utilized for feature selection to identify the most influential factors affecting drug concentrations. The performance of each algorithm with popPK parameters was superior to that without popPK parameters. Our final ensemble model, composed of support vector regression, light gradient boosting machine, and categorical boosting in a 6:3:1 ratio, included 16 optimized features. This model demonstrated superior predictive accuracy compared to models utilizing all features, with testing group metrics including an R2 of 0.656, mean absolute error of 3.458, mean square error of 28.103, absolute accuracy within ± 5 mg/L of 81.82%, and relative accuracy within ± 30% of 76.62%. This study presents a rapid and cost-effective predictive model for estimating vancomycin plasma concentrations in elderly patients. The model offers a valuable tool for clinicians to accurately determine effective plasma concentration ranges and tailor individualized dosing regimens, thereby enhancing therapeutic outcomes and safety.
