ABSTRACT

BACKGROUND: Stage III non-small cell lung cancer (NSCLC) is a heterogeneous disease with different subtypes, multidisciplinary teams-led management, and a poor prognosis. Currently, the clinical benefits of stage III NSCLC in the neoadjuvant setting are still unclear. We performed a meta-analysis of published data on neoadjuvant chemoimmunotherapy in stage III NSCLC to systematically evaluate its efficacy and safety.

METHODS: We searched the databases to identify eligible studies of neoadjuvant chemoimmunotherapy for stage III NSCLC. The primary outcomes mainly included pathological and radiological response outcomes, the feasibility of surgery, and the safety of the regimen. The pathological and radiological response included the rate of major pathologic response (MPR), complete pathologic response (pCR), radiological response outcomes, and R0 resection; The feasibility included the rate of surgical resection, conversion to thoracotomy, surgical complications, pathological downstaging of clinical disease stage. The safety included the incidence of treatment-related adverse events (TRAEs) and severe adverse events (SAEs). R 4.1.3 software was conducted for data analysis, and p < 0.05 was considered statistically significant.

RESULTS: Nine trials containing a total of 382 populations were eligible for the meta-analysis, with the pooled surgical resection rate of 90%. Owing to the large heterogeneity of the single-rate meta-analysis, the random effect model was adopted. The estimated pooled prevalence of MPR was 56% (95%CI 0.39-0.72) and of pCR was 39% (95%CI 0.28-0.51). The pooled rate of TRAEs was 65% (95%CI 0.17-0.99) and SAEs was 24% (95%CI 0.05-0.49).

CONCLUSION: Compared to neoadjuvant chemotherapy or immunotherapy, neoadjuvant chemoimmunotherapy achieved more pathological and radiological relief, and has a high surgical resection rate and low risk of conversion to thoracotomy and surgical complications, with poor tolerance of toxicity but rarely developing life-threatening adverse events. In conclusion, neoadjuvant chemoimmunotherapy is suggested to be beneficial for stage III NSCLC.

ABSTRACT

OBJECTIVE: This study aimed to determine the level of life satisfaction and identify associated factors among elderly people living in two cities in northwest Ethiopia.

DESIGN: Community-based cross-sectional study.

SETTING: Two cities in northwest Ethiopia (Gondar and Bahir Dar).

PARTICIPANTS: 816 elderly people age 60 years and above living in Gondar and Bahir Dar, northwest Ethiopia. Systematic random sampling was used to select study participants.

MAIN OUTCOME MEASURE: Level of life satisfaction. Considering the mean and SD, three levels of satisfaction appeared to suffice as the basis for analysis and discussion: 23.5-34.4 dissatisfied, 34.5-56.5 averagely satisfied and 56.6-67.5 satisfied. Multivariable ordinal regression analysis was done to control the confounders. Since the outcome variable has an ordinal category, ordinal regression analysis is appropriate. A p≤0.05 and AOR (adjusted OR) with a 95% CI were considered to determine the statistically significant variables and strength of the association.

RESULTS: The mean age of the respondents was 68.2 years with an SD±7.2. The level of life satisfaction was: dissatisfied 17.2%, moderately satisfied 63.8% and well satisfied 19.0%. Overall, 45.8% (95% CI 42.2% to 49.2%) of the participants had a score equal to or above the mean. Regarding associated factors; retired current occupation (AOR=2.23, 95% CI 1.09 to 4.55), good self-rated health status (AOR=2.54, 95% CI 1.29 to 4.99), having no chronic disease (AOR=1.48, 95% CI 1.03 to 2.11), somewhat-good (AOR=2.15, 95% CI 1.12 to 4.13) and good (AOR=4.51, 95% CI 2.40 to 8.45) self-perception on ageing life, moderate functional impairment on daily living activities (AOR=5.43, 95% CI 1.81 to 16.24), high sense of coherence (AOR=3.80, 95% CI 2.04 to 7.08), house rent as a source of finance (AOR=2.60, 95% CI 1.49 to 4.52) and high perceived social support (AOR=2.13, 95% CI 1.44 to 3.16) had statistically significant association with the life satisfaction.

CONCLUSION: The life satisfaction level in our study group was lower than in some more highly developed countries. To improve the level of life satisfaction in Ethiopia, a holistic programme of nursing care for elderly people, particularly as concerns about their health and psychosocial conditions is crucial in both community and clinical settings.

ABSTRACT

OBJECTIVES: To explore whether the minimally invasive oesophagectomy (MIE) or hybrid minimally invasive oesophagectomy (HMIE) are associated with better nutritional status and less weight loss 1 year after surgery, compared with open oesophagectomy (OE).

DESIGN: Prospective cohort study.

SETTING: All patients undergoing oesophagectomy for cancer in Sweden during 2013-2018.

PARTICIPANTS: A total of 424 patients alive at 1 year after surgery were eligible, and 281 completed the 1-year assessment. Of these, 239 had complete clinical data and were included in the analysis.

PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome was nutritional status at 1 year after surgery, assessed using the abbreviated Patient-Generated Subjective Global Assessment questionnaire. The secondary outcomes included postoperative weight loss at 6 months and 1 year after surgery.

RESULTS: Of the included patients, 78 underwent MIE, 74 HMIE while 87 patients underwent OE. The MIE group had the highest prevalence of malnutrition (42% vs 22% after HMIE vs 25% after OE), reduced food intake (63% vs 45% after HMIE vs 39% after OE), symptoms reducing food intake (60% vs 45% after HMIE vs 60% after OE) and abnormal activities/function (45% vs 32% after HMIE vs 43% after OE). After adjustment for confounders, MIE was associated with a statistically significant increased risk of reduced food intake 1 year after surgery (OR 2.87, 95% CI 1.47 to 5.61), compared with OE. Other outcomes were not statistically significantly different between the groups. No statistically significant associations were observed between surgical techniques and weight loss up to 1 year after surgery.

CONCLUSIONS: MIE was statistically significantly associated with reduced food intake 1 year after surgery. However, no differences were observed in weight loss between the surgical techniques. Further studies on nutritional impact of surgical techniques in oesophageal cancer are needed.

ABSTRACT

OBJECTIVE: The aim of this study was to assess knowledge and factors associated with obstetrics danger signs among married men in Dessie town, North-East Ethiopia in 2020.

DESIGN: Community-based cross-sectional study.

SETTING: Dessie town, North-East Ethiopia.

PARTICIPANTS: The study was conducted on selected 824 men. The data were collected through face-to-face interviews using pretested questionnaires and then the data were entered into Epi-Data V.3.1 software, and analysis was carried out using Statistical Package for the Social Sciences V.20. Bivariable and multivariable logistic regression analyses were used to determine the association between each independent variable with the dependent variable, and those variables with a value of p≤0.25 in bivariable analysis were candidates for multivariable analysis. Finally those variables with a value of p<0.05 with 95% CI in multivariable analysis were reported as statistically significant.

RESULT: This study revealed that the overall knowledge of obstetric danger signs was 53.8% (95% CI 50.2 % to 57.2%). Respondents aged 35-40 years (AOR=4.92, 95% CI 2.6 to 9.0), exposure to media (AOR=10.4, 95% CI 4.19 to 25.9), wife’s age ≤35 years (AOR=4.16, 95% CI 2.25 to 7.69), wife who attended secondary education (AOR=1.59, 95% CI 1.06 to 2.39), participation in the Health Development Army (AOR=4.74, 95% CI 1.8 to 12.5), previous obstetric complication (AOR=4.27, 95% CI 2.0 to 9.14) and number of pregnancy ≤2 (AOR=0.42, 95% CI 0.05 to 3.38) and 3-4 (AOR=0.22 95% CI 0.06 to 0.83) were significantly associated with knowledge of obstetric danger signs.

CONCLUSION: Men’s knowledge about obstetric danger signs was low. Age of respondents, wives’ age, and respondents’ media exposure, participation in the Health Development Army, wives’ educational status, previous obstetrics complication and gravidity were significantly associated knowledge of obstetrics danger sign.

ABSTRACT

BACKGROUND: Numerous studies have suggested significant associations between prenatal exposure to heavy metals and newborn anthropometric measures. However, little is known about the effect of various heavy metal mixtures at relatively low concentrations. Hence, this study aimed to investigate associations between prenatal exposures to a wide range of individual heavy metals and heavy metal mixtures with anthropometric measures of newborns.

METHODS: We recruited 975 mother-term infant pairs from two major hospitals in Israel. Associations between eight heavy metals (arsenic, cadmium, chromium, mercury, nickel, lead, selenium, and thallium) detected in maternal urine samples on the day of delivery with weight, length, and head circumference at birth were estimated using linear and Bayesian kernel machine regression (BKMR) models.

RESULTS: Most heavy metals examined in our study were observed in lower concentrations than in other studies, except for selenium. In the linear as well as the BKMR models, birth weight and length were negatively associated with levels of chromium. Birth weight was found to be negatively associated with thallium and positively associated with nickel.

CONCLUSION: By using a large sample size and advanced statistical models, we could examine the association between prenatal exposure to metals in relatively low concentrations and anthropometric measures of newborns. Chromium was suggested to be the most influential metal in the mixture, and its associations with birth weight and length were found negative. Head circumference was neither associated with any of the metals, yet the levels of metals detected in our sample were relatively low. The suggested associations should be further investigated and could shed light on complex biochemical processes involved in intrauterine fetal development.

ABSTRACT

OBJECTIVE: The Enhanced Recovery after Surgery Cardiac Society recommends using multimodal analgesia (MMA) for postoperative pain however, evidence-based guidelines have yet to be established. This study examines the impact of a standardized postoperative MMA pathway in reducing opioid consumption and related complications after cardiothoracic surgery (CTS).

METHODS: Within a multicenter healthcare system, a postoperative MMA pathway was developed and implemented at two CTS intensive care units (ICU) while the other CTS ICU opted to maintain the existing opioid-based pathway. A retrospective chart review was conducted on patients admitted to a CTS ICU within this healthcare system after conventional coronary artery bypass grafting and/or valve surgery from September 1, 2018, to June 30, 2019. Comparative analysis was conducted on patients prescribed MMA versus those managed with an opioid-based pathway. The primary outcome was total opioid consumption, converted to morphine milligram equivalents, 72-h post-surgery. Secondary outcomes included mobility within one-day post-surgery, ICU length of stay (LOS), time to first bowel movement (BM), and time to first zero Richmond Agitation-Sedation Scale (RASS).

RESULTS: Seven hundred sixty-two adults were included for final analysis. The MMA group had a higher body mass index, higher percentage of females, were more likely classified as African American and had higher scores for risk-adjusted complications. General Linear Model analysis revealed higher opioid consumption in the MMA group (Est. 0.22, p < 0.0009); however, this was not statistically significant after adjusting for differences in fentanyl usage. The MMA group was more likely to have mobility within one-day post-surgery (OR 0.44, p < 0.0001), have longer time to first BM (OR 1.93, p = 0.0011), and longer time to first zero RASS (OR 1.62, p = 0.0071). The analgesia groups were not a predictor for ICU LOS.

CONCLUSIONS: Opioid consumption was not reduced secondary to this postoperative MMA pathway. The MMA group was more likely to have mobility within one-day post-surgery. Patients in the MMA group were also more likely to have prolonged time to first BM and first zero RASS. Development and evaluation of a perioperative MMA pathway should be considered.

ABSTRACT

BACKGROUND: Patient reported outcome measures (PROM) can improve patient care and be crucial for symptom tracking especially during disease outbreaks. FLU-PRO Plus is a validated PROM used to track viral respiratory symptoms. Our study aimed to evaluate the feasibility of using FLU-PRO© Plus, to track symptoms across three healthcare systems.

METHODS: The prospective, longitudinal study recruited adults between February-May 2021 from HealthPartners Institute (HP), Kaiser Permanente Georgia (KPGA), and Kaiser Permanente Mid-Atlantic States (KPMAS). Adult members were eligible if they had a positive lab or diagnosis for either COVID-19 or influenza-like illness (ILI) or exhibited 2 + viral respiratory symptoms. Descriptive statistics were calculated to describe the patient characteristics for participants that were eligible for FLU-PRO Plus, successfully contacted, attempted to log in to the FLU-PRO Plus website, and participants who completed FLU-PRO Plus Day 1. Bivariable and multivariable logistic regression using PROC GLIMMIXX investigated the patient characteristics associated with (1) successful contact and (2) FLU-PRO Plus Day 1 completion.

RESULTS: We identified a total of 15,650 eligible participants during the enrollment period: 9,582 from HP, 1,740 from KPGA, and 4,328 from KPMAS. Among the total of 409 eligible adults who attempted to participate in FLU-PRO Plus, 317 completed FLU-PRO Plus Day 1. Among the 317 individuals that completed FLU-PRO Plus Day 1, 205 (67.5%) were diagnosed with COVID-19; 112 adults diagnosed with COVID-19 completed FLU-PRO Plus Day 14. Among adults successfully contacted, adults aged 35-64 (OR = 1.40, 95% CI 1.05, 1.87), females (OR = 1.77, 95% CI 1.38, 2.27), and adults diagnosed with COVID-19 (OR = 1.66, 95% CI 1.27, 2.17) had higher odds of completing FLU-PRO Plus Day 1; Asian adults (OR = 0.38, 95% CI 0.19, 0.76) and Black and African American adults (OR = 0.33, 95% CI 0.19, 0.76) had lower odds compared to White adults.

CONCLUSION: Our study reports on the feasibility of patients across three integrated healthcare systems utilizing FLU-PRO Plus to monitor their respiratory symptoms. Patient reported outcome measures (PROM) can improve patient care, quality of life, and reduce the strain of limited resources on healthcare systems. Future FLU-PRO Plus studies should develop an implementation strategy to fully integrate FLU-PRO Plus within clinical care and patient management.

ABSTRACT

BACKGROUND: The multistep molecular model of breast carcinogenesis is based on the oestrogen receptor(ER) status of the tumour. Its two main arms comprise ER-positive and ER-negative breast carcinomas(BCa), which are associated with Nottingham grade(NG) of the tumour and different proliferative epithelial changes. According to the model, columnar cell lesions(CCL), lobular carcinoma in-situ(LCIS) and atypical ductal hyperplasia(ADH), low-grade ductal carcinoma in-situ (LG-DCIS) are associated with low grade ER-positive tumours and microglandular adenosis (MGA), pleomorphic LCIS(PLCIS), high-grade DCIS(HG-DCIS) are associated with ER-negative high grade tumours. This study aims to describe the association between proliferative epithelial changes in breast tissue adjacent to tumour, in relation to the ER status and NG of the tumour.

METHODS: This descriptive cross-sectional study included 420, wide local excision and mastectomy specimens of BCa from National Hospital of Sri Lanka, between 2017-2019. The histopathological features of the tumour and proliferative epithelial changes in tumour adjacent tissue within 10 mm distance from the tumour-host interface were evaluated independently by two pathologists. The ER, PR(Progesterone receptor) and HER2 status assessed by immunohistochemistry(IHC) was reviewed. The associations between above epithelial lesions and ER status and NG{categorised as low grade (NG1 and NG2) and high grade (NG3)} of the tumour were analyzed.

RESULTS: ER positive BCa showed significant associations with CCH (p = 0.04), FEA (p = 0.035) and LGDCIS (p < 0.001). Although PLCIS was more frequent in ER positive tumours, the association did not attain statistical significance. ER negative BCa showed a significant association with HGDCIS (p = 0.016). CCLs as a whole (p = 0.005) and also CCC (p = 0.006) and FEA (p = 0.048) and LGDCIS (p < 0.001) showed significant associations with low NG tumours. High NG tumours showed a significant association with HGDCIS (p < 0.001). Microglandular adenosis was not identified in our study population.

CONCLUSION: These morphological findings support the multistep molecular based pathogenetic pathways of breast carcinoma in the studied setting in South Asia. Identification of these proliferative epithelial components in a core biopsy that is negative for BCa, should prompt for close clinicoradiological correlation, and if necessary re-biopsy of women suspected of harbouring a BCa.

ABSTRACT

BACKGROUND: The loss of the fetus may cause mental health problems in women. The present study aimed to determine the effect of mindfulness-based stress reduction (MBSR) on anxiety, depression, and stress in women with early pregnancy loss.

METHODS: This study was performed on 106 women with early pregnancy loss in Shiraz, Iran. The intervention group underwent eight counselling sessions. Pre-test and post-test were performed in both groups with the Depression, Anxiety, and Stress Scale (DASS) 21 questionnaire. Data were analyzed by SPSS 23.

RESULTS: There was a statistically significant difference between the mean scores in the intervention group vs. the control group in terms of anxiety (7.9 ± 1.07 vs. 13.79 ± 5.36, respectively), stress (9.26 ± 1.25 vs.18.13 ± 7.66, respectively), and depression (7.83 ± 1.05 vs.16.26 ± 11.06, respectively) (P < 0.0001).

CONCLUSIONS: MBSR can be suggested to promote women’s mental health.

ABSTRACT

AIM: This study aimed to determine the effect of the Benson relaxation technique on the severity of symptoms and quality of life in children with irritable bowel syndrome (IBS).

DESIGN: This quasi-experimental study was carried out on children with irritable bowel syndrome in Iran.

METHOD: Sixty children were randomly divided into control and experimental groups. The Benson relaxation technique was implemented for three weeks for experimental group, while the control group only received the typical medical therapy with no special intervention. The questionnaire of Irritable Bowel Syndrome-quality of life-34 (IBS-QOL-34), and Bowel Symptoms Severity and Frequency Scale (BSS-FS) were used for data gathering before and three weeks after the intervention. Data were analyzed using statistics, appropriate parametric and non-parametric tests.

RESULTS: According to the results, the experimental group had lower mean scores of qualities of life before the intervention (p < 0.05). The mean score of symptom severity in children with IBS was 13.88 in the experimental group, which changed to 9.83 in the post-test, indicating a significant difference (p < 0.000). The pre-test and post-test mean scores for quality of life in this group were 118.94 and 102.77, respectively, indicating a significant difference (P < 0.001).

CONCLUSION: The Benson relaxation technique can be a non-pharmacological solution to reduce the severity of symptoms and improve the quality of life of children with IBS.

IMPLICATION TO PRACTICE: This technique is supposed to contribute as a further intervention in clinical contexts.
