ABSTRACT

PURPOSE: In this study, we aimed to determine the factors which affect post-progression survival (PPS) and overall survival (OS) in patients with metastatic colorectal cancer.

METHODS: 87 patients with metastatic colorectal cancer had been followed up with palliative care due to disease progression or ECOG performance status after receiving at least two cycles of chemotherapy. PPS was estimated as the time between the last progression date and last control or death date in patients who were followed up with palliative care.

RESULTS: 87 patients with metastatic colorectal cancer were included in the study. Evaluation with multivariate analysis of factors affecting PPS revealed a significantly longer PPS (10.8 weeks) in patients with ECOG score 0 or 1 than the PPS of patients with ECOG score 2-5 (3 weeks) (p=0.01). It was also found that PPS was 14.4 weeks in patients with CEA levels <5ng/ml,while it was 6.7 weeks in patients with CEA levels ≥5 ng/ml (p=0.001) and PPS was 13.7 weeks in patients with controlled disease after first-line chemotherapy while it was 8 weeks in patients with progression (p=0.03); both were statistically significant. No significant association was found between PPS and age, gender, tumor location, sites of metastasis, and RAS status.

CONCLUSION: ECOG performance status score of 0-1, CEA levels below 5 ng/ml, and disease control with first-line chemotherapy are related to longer PPS in patients with metastatic colorectal cancer.

ABSTRACT

PURPOSE: The purpose of the present study was to assess the perceived symptoms, depression and quality of life (QoL) in advanced lung cancer patients undergoing chemotherapy.

METHODS: The study was cross sectional and was conducted in the oncology department of General Hospital “George Papanikolaou”, Thessaloniki, Greece. The sample was convenient and consisted of 76 advanced lung cancer patients. A questionnaire including instruments such as Center for Epidemiologic Studies Depression Scale- CES-D, Revised Edmonton Symptom Assessment Scale r-ESAS, EORTC QLQ-C30 and demographic and clinical information was used to collect data.

RESULTS: The most frequently observed symptoms were tiredness, shortness of breath, anxiety and well-being. The vast majority of patients (75.3%) had total score in CES-depression higher than 16. The type of residence affected ESAS emotional score (p=0.010). Gender affected the level of depression (p=0.014) and the type of lung cancer affected depression (p=0.036). The type of residence affected emotional functioning (p=0.010), the type of treatment influenced the score of global health status (p=0.007), the role functioning (p=0.032) and social functioning (p=0.024). Multivariate regression analysis was conducted to identify the predictors of overall QoL and depression. The statistically significant factors for QoL were pain (p<0.001) and tiredness (p=0.003), while the type of lung cancer (p<0.007), the type of insurance (p<0.025) and the type of treatment (p<0.041) influenced depression as well.

CONCLUSIONS: Advanced lung cancer patients experienced moderate level in QoL and mild levels of symptoms. Demographic and clinical characteristics influenced depression and QoL.

ABSTRACT

OBJECTIVES: The objective of this study was to identify the incidence of inferior alveolar nerve (IAN) injury after extraction of mandibular third molars with confirmed “high-risk” features on cone beam computed topography scans and establish any risk factors that significantly increase the chances of sustaining an IAN injury.

STUDY DESIGN: This study is a retrospective analysis of outcomes after surgical extraction of 500 mandibular third molars over a 5-year period. All teeth showed signs of contact with or compression of the IAN on cone beam computed topography scans.

RESULTS: The overall incidence of IAN injury was 6.6%, with permanent neuropathies accounting for 1.8% within this high-risk cohort. Statistically significant factors shown to increase the risk of nerve injury included increasing age (P = .002), compression of the nerve evident on cone beam computed topography scan (P = .005), and buccal or interradicular position of the nerve (P = .042).

CONCLUSIONS: Results indicate a low incidence of IAN injury, particularly given the high-risk nature of all teeth that were extracted. It highlights the benefits of cone beam computed topography scans in surgical planning. These data are an important contribution to the existing literature and valuable in the consent procedure for patients undergoing surgical removal of mandibular third molars in contact with the IAN.

ABSTRACT

BACKGROUND: Critically ill patients in intensive care units (ICUs) often acquire opportunistic infections or are colonized by vancomycin-resistant enterococci (VRE), which limits therapeutic options and results in high case-fatality rates. In clinical practice, the beneficial effects of universal chlorhexidine gluconate (CHG) bathing on the control of VRE remain unclear. This study aimed to investigate whether 2% CHG daily bathing reduced the acquisition of VRE in the setting of a medical ICU (MICU) with VRE endemicity.

METHODS: This quasi-experimental intervention study was conducted in a 23-bed MICU of a tertiary care hospital in Korea from September 2016 to December 2017. In a prospective, interrupted time-series analysis (ITS) with a 6-month CHG bathing intervention, we compared the acquisition and incidence of VRE and the incidence of methicillin-resistant Staphylococcus aureus (MRSA) and carbapenem-resistant Acinetobacter baumannii (CRAB) between the pre-intervention and intervention periods. The primary and secondary outcomes were a change in the acquisition of VRE and incidence of VRE, MRSA, or CRAB between the two periods, respectively.

RESULTS: All the adult patients admitted to the MICU were enrolled in the pre-intervention (n = 259) and intervention (n = 242). The overall CHG daily bathing compliance rate was 72.5%. In the ITS, there was a significant intervention effect with a 58% decrease in VRE acquisition (95% CI 7.1-82.1%, p = 0.038) following the intervention. However, there was no significant intervention effects on the incidence trend of VRE, MRSA, and CRAB determined by clinical culture between the pre-intervention and intervention periods.

CONCLUSION: In this real-world study, we concluded that daily bathing with CHG may be an effective measure to reduce VRE cross-transmission among patients in MICU with a high VRE endemicity.

ABSTRACT

BACKGROUND: Female sexual dysfunction has a high prevalence in women in the postmenopausal period. Not only factors like comorbidities and chronic illnesses are responsible for this high prevalence, but also psychological and interpersonal factors play a significant role. Sexual counselling educational programs have shown positive sexual behavioral changes and they should be considered the first line approach to female sexual dysfunction in this group of women.

AIM: To review the evidence of the efficacy of sexual counselling educational programs for sexual dysfunction in postmenopausal women.

METHODS: A systematic search was performed in February 2021 from electronic databases (MEDLINE, CENTRAL, and Scopus), unpublished studies, ongoing clinical trials, conference abstracts and journal archives, dissertations and theses, gray literature and free search on the Google Scholar search engine. Studies that evaluate the effectiveness of sexual educational programs in postmenopausal women were selected. Study selection and data extraction were performed by 2 independent researchers. Extracted data included author identification, publication date, geographic location, study population and sample size, type of intervention, sexual function evaluation tool and outcome. Studies that evaluate sexual function by using the Female Sexual Function Index (FSFI) were included in the meta-analysis, calculating the mean difference.

OUTCOMES: Improvement of sexual function in postmenopausal women.

RESULTS: We included 8 studies in the systematic review, 6 randomized and 2 nonrandomized controlled trials, with a total sample size of 619 women, aged between 39 and 75 years old, all in menopause for less than 5 years. The studies described sexual education programs, with 4-10 sessions, 45-60 minutes each, including themes like sexual anatomy, physiological sexual response, menopause, methods of stimulation, and common sexual myths. Five studies also included cognitive-behavior therapy and 3 studies assessed mindfulness techniques. Six studies evaluated the effectiveness of sexual educational programs using FSFI. The results showed that sexual counselling educational programs had statistically significant effects on enhancing the total FSFI score (mean difference = +7.14, 95% confidence interval = 3.70-10.6, P < .0001) in comparison to routine care. Results were also significant in all evaluated sex domains: pain, arousal, lubrication, desire, orgasm and satisfaction (P < .05).

CONCLUSION: Our meta-analysis shows that sexual counselling educational programs are effective in improving sexual dysfunction in postmenopausal women when compared to routine care. These are simple approaches, easily administered with minimal resources that help prevent the psychological and social consequences of sexual dysfunction at this age.

ABSTRACT

BACKGROUND: High-dose melphalan (HDMEL, 200 mg/m²) is considered as the standard conditioning regimen for autologous hematopoietic stem cell transplantation (auto-HSCT) in multiple myeloma (MM). However, whether the combination of melphalan with busulfan (BUMEL) conditioning outperforms HDMEL remains controversy. Accordingly, a systematic review and meta-analysis was carried out to compare the outcomes of HDMEL and BUMEL-based conditioning regimens in newly diagnosed MM patients having undergone auto-HSCT.

METHODS: A systematic literature search was conducted in PubMed, Embase and Cochrane Library database until July 31, 2021, to identify all eligible studies comparing progression-free survival (PFS), overall survival (OS), optimal treatment response after auto-HSCT, duration of stem cell engraftment and incidence of toxic events between patients undergoing BUMEL-based and HDMEL conditioning regimens. Hazard ratio (HR), mean difference (MD) or odds ratio (OR) corresponding to 95% confidence interval (CI) were determined to estimate outcomes applying RevMan 5.4 software. Publication biases were assessed by performing Egger’s test and Begg’s test by Stata 15 software.

RESULTS: Ten studies with a total of 2855 MM patients were covered in the current meta-analysis. The results of this study demonstrated that patients having received BUMEL-based regimen was correlated with longer PFS (HR 0.77; 95% CI 0.67~0.89, P = 0.0002) but similar OS (HR 1.08; 95% CI 0.92~1.26, P = 0.35) compared with those having received HDMEL. The differences of best treatment response after auto-HSCT and duration of neutrophil or platelet engraftment did not have statistical significance between the two groups of patients. With respect to adverse effects, the patients in BUMEL-based group were less frequently subject to gastrointestinal toxicity while the patients in HDMEL group less often experienced mucositis and infection. No significant difference was observed in hepatic toxicity between the two groups of patients.

CONCLUSIONS: In the present study, BUMEL-based conditioning was identified as a favorable regimen for a better PFS and equivalent OS as compared with HDMEL, which should be balanced against higher incidences of mucositis and infection. BUMEL-based conditioning is likely to act as an alternative strategy to more effectively improve auto-HSCT outcomes in MM.

ABSTRACT

BACKGROUND: Metabolic syndrome is a major public health challenge in both developed and developing countries. The burden of this disease is high, even in patients with psychiatric disorders. However, very little is known about the association between metabolic syndrome and psychiatric illness in Ethiopia. Therefore, the aim of this study was to investigate the magnitude of metabolic syndrome and its components among psychiatric clients.

METHODS: A comparative cross-sectional study was undertaken between psychiatric patients and age-and sex-matched non-psychiatric controls at the Dilchora referral hospital. The study included 192 study participants (96 psychiatric patients and 96 non- psychiatric controls from general medical and surgical patients). The National Cholesterol Education Program: Adult Treatment Panel III criteria were used to diagnose metabolic syndromes. The data were cleaned and analyzed using the Statistical Package for Social Sciences, Version 21. All intergroup comparisons for continuous data were performed using an independent sample t-test, whereas categorical data were analyzed using the Chi-square test. Logistic regression analysis was used to identify the association between metabolic syndrome and the associated variables.

RESULTS: The magnitude of metabolic syndrome among psychiatric patients was 36.5% (95%CI: 27.6, 47.4) compared to non-psychiatric control patients, 21.9% (95%CI: 13.5, 30.3), p = 0.02. The prevalence of MetS components, such as waist circumference (25.0% vs. 14.3%), lower-high density lipoprotein level (35.4% vs. 20.8%), higher systolic blood pressure (41.7% vs. 29.2%) and higher fasting blood glucose (40.6% vs. 18.8%) showed statistically significant differences between the exposed and non-exposed groups. Age greater than 50 years (AOR: 2.8, CI: 1.14, 20.0, p < 0.05); being female (AOR: 7.4, CI: 2.0, 27.6, p < 0.05), being urban residence (AOR: 6.4, CI: 2.2, 20.6, p < 0.05), ever alcohol intake (AOR: 5.3, CI: 1.3, 21.2), being physically inactive (AOR: 3.52, CI: 1.1, 12.9, p < 0.05) and family history of hypertension (AOR: 2.52, CI: 1.1, 12.2, p < 0.05) were independent predictors of metabolic syndrome (p < 0.05).

CONCLUSIONS: There is a high burden of metabolic syndrome and its components in patients with severe psychiatric disorders. Therefore, screening and mitigation strategies for metabolic syndrome and their components should be implemented in the management of psychiatric disorders.

ABSTRACT

BACKGROUND: The currently used malaria vaccine, RTS,S, is designed based on the Plasmodium falciparum circumsporozoite protein (PfCSP). The pfcsp gene, besides having different polymorphic patterns, can vary between P. falciparum isolates due to geographical origin and host immune response. Such aspects are essential when considering the deployment of the RTS,S vaccine in a certain region. Therefore, this study assessed the genetic diversity of P. falciparum in Sudan based on the pfcsp gene by investigating the diversity at the N-terminal, central repeat, and the C-terminal regions.

METHODS: A cross-sectional molecular study was conducted; P. falciparum isolates were collected from different health centres in Khartoum State between January and December 2019. During the study period, a total of 261 febrile patients were recruited. Malaria diagnosis was made by expert microscopists using Giemsa-stained thick and thin blood films. DNA samples were examined by the semi-nested polymerase chain reaction (PCR). Single clonal infection of the confirmed P. falciparum cases, were used to amplify the pfcsp gene. The amplified amplicons of pfcsp have been sequenced using the Sanger dideoxy method. The obtained sequences of pfcsp nucleotide diversity parameters including the numbers of haplotypes (Hap), haplotypes diversity (Hapd), the average number of nucleotide differences between two sequences (p), and the numbers of segregating sites (S) were obtained. The haplotype networks were constructed using the online tcsBU software. Natural selection theory was also tested on pfcsp using Fuand Li’s D, Fuand Li’s F statistics, and Tajima’s D test using DnaSP.

RESULTS: In comparison with the different pfcsp reference strains, the Sudanese isolates showed high similarity with other African isolates. The results of the N-terminal region showed the presence of 2 different haplotypes with a Hapd of 0.425 ± 0.00727. The presence of the unique insertion of NNNGDNGREGKDEDKRDGNN was reported. The KLKQP motif was conserved in all the studied isolates. At the central repeat region, 11 haplotypes were seen with a Hapd of 0.779 ± 0.00097. The analysis of the genetic diversity in the C-terminal region showed the presence of 10 haplotypes with a Hapd of 0.457 ± 0.073. Several non-synonymous amino acids changes were also seen at the Th2R and the Th3R T-cell epitope regions including T317K, E317K, Q318E, K321N, I322K, T322K, R322K, K324Q, I327L, G352N, S354P, R355K, N356D, Q357E, and E361A.

CONCLUSIONS: In this study, the results indicated a high conservation at the pfcsp gene. This may further contribute in understanding the genetic polymorphisms of P. falciparum prior to the deployment of the RTS,S vaccine in Sudan.

ABSTRACT

BACKGROUND: Total hip arthroplasty (THA) for developmental dysplasia of the hip (DDH) is a complex procedure due to associated anatomical abnormalities. We studied the extent to which preoperative digital templating is reliable when performing cementless THA in patients with DDH.

METHODS: We templated and compared the pre- and postoperative sizes of the acetabular and femoral components and the center of rotation (COR), and analysed the postoperative cup coverage, leg length discrepancy (LLD), and stem alignment in 50 patients (56 hips) with DDH treated with THA.

RESULTS: The implant size exactly matched the template size in 42.9% of cases for the acetabular component and in 38.2% of cases for the femoral component, whereas the templated ±1 size was used in 80.4 and 81.8% of cases for the acetabular and femoral components, respectively. There were no statistically significant differences between templated and used component sizes among different DDH severity levels (acetabular cup: p = 0.30 under the Crowe classification and p = 0.94 under the Hartofilakidis classification; femoral stem: p = 0.98 and p = 0.74, respectively). There were no statistically significant differences between the planned and postoperative COR (p = 0.14 horizontally and p = 0.52 vertically). The median postoperative LLD was 7 (range 0-37) mm.

CONCLUSION: Digital preoperative templating is reliable in the planning of cementless THA in patients with DDH.

ABSTRACT

BACKGROUND: For children and adults, the standard treatment for obstructive sleep apnea is the delivery of continuous positive airway pressure (CPAP). Though effective, CPAP masks can be uncomfortable to patients, contributing to adherence concerns. Recently, nasal high flow (NHF) therapy has been investigated as an alternative, especially in CPAP-intolerant children. The present study aimed to compare and contrast the positive airway pressures and expired gas washout generated by NHF versus CPAP in child nasal airway replicas.

METHODS: NHF therapy was investigated at a flow rate of 20 L/min and compared to CPAP at 5 cmH₂O and 10 cmH₂O for 10 nasal airway replicas, built from computed tomography scans of children aged 4-8 years. NHF was delivered with three different high flow nasal cannula models provided by the same manufacturer, and CPAP was delivered with a sealed nasal mask. Tidal breathing through each replica was imposed using a lung simulator, and airway pressure at the trachea was recorded over time. For expired gas washout measurements, carbon dioxide was injected at the lung simulator, and end-tidal carbon dioxide (EtCO₂) was measured at the trachea. Changes in EtCO₂ compared to baseline values (no intervention) were assessed.

RESULTS: NHF therapy generated an average positive end-expiratory pressure (PEEP) of 5.17 ± 2.09 cmH₂O (mean ± SD, n = 10), similar to PEEP of 4.95 ± 0.03 cmH₂O generated by nominally 5 cmH₂O CPAP. Variation in tracheal pressure was higher between airway replicas for NHF compared to CPAP. EtCO₂ decreased from baseline during administration of NHF, whereas it increased during CPAP. No statistical difference in tracheal pressure nor EtCO₂ was found between the three high flow nasal cannulas.

CONCLUSION: In child airway replicas, NHF at 20 L/min generated average PEEP similar to CPAP at 5 cm H₂O. Variation in tracheal pressure was higher between airway replicas for NHF than for CPAP. The delivery of NHF yielded expired gas washout, whereas CPAP impeded expired gas washout due to the increased dead space of the sealed mask.
