ABSTRACT

PURPOSE: Little is known about the relationships between apathy, depressive symptoms and interdialytic weight gain (IDWG) in patients on chronic hemodialysis. Aim of the present study is to investigate the association between IDWG and symptoms of depression and apathy in hemodialysis patients.

METHODS: A total of 139 chronic patients of the HD units between January 2020 and December 2021 were included in the present cross-sectional study. IDWG was calculated as the difference between the pre-HD weight and the weight registered after the previous session; the average of the sessions in a month was registered. Apathy Evaluation Scale (AES) was adopted to evaluate apathy. Depression was assessed by Beck Depression Inventory (BDI).

RESULTS: Ninety-three patients had IDWG% ≤ 4 and 46 had an IDWG% > 4. Correlation between IDWG% and BDI as well that between IDWG% and AES were not statistically significant. Median BDI and mean AES did not differ significantly between the groups. In addition, 104 patients had a BDI < 16 and 35 had a BDI ≥ 6. Seventy-five patients had an AES score ≤ 35 and 63 had a AES score > 35. The IDWG (kg) and the IDWG% did not differ significantly between the two groups.

CONCLUSION: IDWG is not associated with symptoms of depression or apathy in hemodialysis patients. Thus, these results may question if the use of behavioral intervention aimed at improving motivation is warranted in the hemodialysis population to reduce the IDWG.

ABSTRACT

There are still some controversies regarding the clinical use of cementless UKAs. The aim of this systematic review was to determine whether cementless medial UKA leads to similar outcomes compared to cemented medial UKA. This search was conducted in accordance with the Preferred Reporting Items for Systematic Reviews guidelines (PRISMA). The random effects model with 95% confidence interval (CI) was applied to the analysis. The I² statistic was used to assess study heterogeneity. Six studies were eligible for inclusion (4784 UKAs, 4776 patients): 2947 cemented UKAs (61.6%) and 1837 cementless UKAs (38.4%). The overall mean follow-up was 4.9 years. The all-cause reoperation rate was 11.3% (80 of 706) at mean 5.7-year follow-up for cemented UKA and 6.9% (57 of 824) at mean 4.1-year follow-up for the cementless. The overall revision rate was 10.2% (303 of 2947) for the cemented and 5.8% (108 of 1837) for the cementless. Aseptic loosening was the most frequent reason of revision (2.3% cemented vs 0.5% cementless). The overall rate of radiolucent lines (RLL) was 28.3% (63 of 223) in the cemented cohort and 11.1% in the cementless (26 of 234). All the studies reported improved functional outcomes. Cementless UKA provides at least equivalent if not better results compared to cemented UKA. Despite the use of cemented UKA outnumber cementless fixation, available data shows that cementless UKA had a reduced midterm revision rate, while providing similar functional outcomes.

ABSTRACT

BACKGROUND: Isocitrate dehydrogenase-1 (IDH1) mutations occur in a significant proportion of intrahepatic cholangiocarcinomas (iCCAs). No data are available regarding the prognostic impact of IDH1 mutations in advanced iCCA patients after progression on first-line therapies.

OBJECTIVE: We investigated the role of IDH1 mutation in advanced iCCA after progression on first-line therapies.

PATIENTS AND METHODS: After progression on first-line therapies for advanced iCCA, consecutive patients were retrospectively collected. The IDH1 status was tested at baseline. This analysis aimed to examine the association between the presence of IDH1 missense mutations and survival outcomes in patients with advanced iCCA treated with a second-line therapy.

RESULTS: The analysis included 119 patients; 56/119 (47%) were IDH1 mutated (IDH1m) and 63/119 (53%) were IDH1 wild type (IDH1 WT). At univariate analysis for overall survival (OS), the presence of IDH1 mutation was associated with a worse median OS (mOS; 8.2 vs. 14.1 months; hazard ratio [HR] 1.9, 95% confidence interval [CI] 1.2-3.0, p = 0.0047). Patients harboring IDH1 mutations showed a worse objective response rate (ORR) compared with patients without IDH1 mutation, whereas no significant differences in disease control rate (DCR) were found. Multivariate analysis confirmed IDH1 mutations as an independent negative prognostic factor for OS (HR 1.7, 95% CI 1.1-2.7, p = 0.0256). By evaluating only patients receiving FOLFOX as second-line therapy, no statistically significant differences were found in terms of both OS and PFS between IDH1m and IDH1 WT patients. In this subset of patients, those harboring an IDH1 mutation showed a worse ORR and DCR compared with those without. Finally, at univariate analysis for OS from third-line treatment, the presence of an IDH1 mutation was associated with a trend toward a worse mOS (6.0 vs. 11.9 months; HR 1.6, 95% CI 0.8-3.2, p = 0.25).

CONCLUSION: The present analysis constitutes the first evidence of a negative prognostic impact of IDH1 mutations in a cohort of patients treated after progression on first-line therapies in contrast to IDH1 inhibitors.

ABSTRACT

When studying wayfinding in urban environments, researchers are often interested in obtaining measures of participants’ survey knowledge, i.e., their estimate of distant locations relative to other places. Previous work showed that distance estimations are consistently biased when no direct route is available to the queried target or when participants follow a detour. Here we investigated whether a corresponding bias is manifested in two other popular measures of survey knowledge: a pointing task and a sketchmapping task. The aim of this study was to investigate whether there is a systematic bias in pointing/sketchmapping performance associated with the preferred route choice in an applied urban setting. The results were mixed. We found moderate evidence for the presence of a systematic bias, but only for a subset of urban locations. When two plausible routes to the target were available, survey knowledge estimates were significantly biased in the direction of the route chosen by the participant. When only one plausible route was available, we did not find a statistically significant pattern. The results may have methodological implications for spatial cognition studies in applied urban settings that might be obtaining systematically biased survey knowledge estimates at some urban locations. Researchers should be aware that the choice of urban locations from which pointing and sketchmapping are performed might systematically distort the results, in particular when two plausible but diverging routes to the target are visible from the location.

ABSTRACT

BACKGROUND: This study investigated the spatial distribution of wild ungulates that pastoralist communities perceive as culprits in the transmission of cattle diseases outside protected areas in southwestern Uganda. Diseases are hypothesized as having influence on pastoralists’ choice of cattle breed types. Until now, there have been no studies conducted on spatial patterns of wild animal species association with cattle breeds reared in Lake Mburo Conservation Area (LMCA), and how diseases transmitted therein potentially influence cattle breed herd sizes.

METHODS: Animal population survey was carried out on cattle and wild ungulate species along transect lines laid perpendicular to the northern boundary of Lake Mburo National Park (LMNP). Data on the costs of cattle mortality and disease control were gathered using face-to-face interviews. We used SPSS version 17 for descriptive statistics to summarize unit cost of disease control at herd level, whereas chi-square (χ2) tests of goodness-of-fit were used to analyze observations on frequency of wild animal sightings, whose association with spatial distribution patterns of cattle breeds was examined using Pearson correlation test.

RESULTS: Our results show inverse association of distance away from LMNP with wild animal populations and the cost of cattle disease control. The mean population of exotic cattle significantly increased as that of indigenous cattle decreased with increasing distance from LMNP. In a similar way, the cost of disease control and cattle abortion incidences were much lower in rangelands far away from LMNP (R² = 0.965, p < 0.001).

CONCLUSION: Spatial distribution of wild ungulates was significantly associated with reported cattle mortality, disease, and cost of disease control. Diseases and their costs of control potentially influenced spatial patterns of cattle breeds and breed herd sizes in LMCA, which in turn could affect range resource use for conserving different species of wild animals outside protected area.

ABSTRACT

Ramadan, a one-month period in which eating and drinking are prohibited from sunrise to sunset, is considered sacred by Muslims. According to Islamic rules, fasting is obligatory for adults and healthy people, but patients and travelers are exempted from this rule. It is not clear whether pregnant women can fast during Ramadan. This cross-sectional case-control study included low-risk pregnant women at 32-37 weeks of gestation in Turkey. We examined healthy women in the last period of their pregnancy and found similar perinatal outcomes between the fasting and nonfasting participants. In the evaluation of fetal well-being, a decrease in the number of accelerations in the non-stress test (NST) and the need to repeat the test were found to be statistically significantly higher in fasting pregnant women. We consider that this may prolong the evaluation period and increase unnecessary hospitalizations due to nonreactive NST results. More randomized controlled trials are needed to conclude that fasting during pregnancy is safe.

ABSTRACT

Chewing khat during pregnancy adversely affects maternal and fetal health, but available studies are scarce and inconsistent, and it is difficult to conclude the relationship between khat consumption and perinatal outcomes. We aimed to investigate the available studies on the effect of khat use during pregnancy on perinatal and maternal outcomes. For this meta-analysis, we conducted a thorough search of articles published in PubMed, Embase, Scopus, and Web of Science up to the date this search was undertaken (03.01.2022). We used random effect model with the Mantel-Haenszel method to calculate the pooled odds ratio and mean difference. We found that khat use during pregnancy was significantly associated with increased odds of low birth weight (OR:2.51; 95% CI: 1.60 to 3.94), congenital anomalies (OR:3.17; 95% CI: 1.30 to 7.73), premature rupture of membrane (OR: 1.99; 95% CI: 1.59 to 2.50), perinatal mortality (OR: 1.95; 95% CI: 1.26 to 3.03), and lower APGAR scores at the fifth minute (MD: -1.7; 95% CI: -2.32 to -1.07). Also, increased odds for developing maternal psychological stress and anemia were reported in women using khat during pregnancy. There were no statistically significant differences in stillbirth and preterm birth between women using khat during pregnancy and their counterparts. Since prenatal khat use is associated with adverse perinatal and maternal outcomes, we strongly recommend equitable and easily accessible health services through the implementation of integrated addiction treatment with maternity services to address khat use during pregnancy and encourage the practice of healthy behavior of women.

ABSTRACT

Chemotherapy-induced peripheral neuropathy (CIPN) is one of the dose-dependent side effects of cisplatin. The loss of sensory neurons is observed in CIPN. There are many methods to minimalize CIPN symptoms such as pharmacological agents and photobiostimulation but the mechanisms of these methods are unclear. Our study is aimed at determining the effects of quercetin and low-level laser therapy (LLLT) in undifferentiated and nerve growth factor-differentiated PC12 cells in cisplatin-induced peripheral neuropathy. PC12 cells with cisplatin were co-treated with quercetin and LLLT (diode pumped all-solid-state laser, 670 nm, output 500 mW, and the laser beam surface area was 1.96 cm²). The effects of quercetin and LLLT on GAP-43 and Synapsin I expressions were analyzed by real-time PCR, cell viability was assessed by MTT assay, Annexin and dead assay measured the induction of apoptosis, the alterations in mitopotential were assessed by mitopotential assay, and lactate dehydrogenase activity in cells was analyzed. All experiment data were analyzed by the Tukey test and applied as a post hoc test, and statistical evaluation was made. Our results indicated that cisplatin increased apoptosis (24,210 ± 2189, 46,504 ± 8246) cells, mitochondrial dysfunction (44,312 ± 0.751, 68,788 ± 1271), and LDH activity (62,821 ± 8245, 87,838 ± 8116). Furthermore, it decreased cell viability (42,447 ± 1780, 36,140 ± 3682) and inhibited GAP-43 and Synapsin I genes in undifferentiated and differentiated PC12 cells. However, apoptosis, the alterations in mitopotential, and lactate dehydrogenase activity decreased by applications of quercetin and LLLT. It has been recommended that quercetin and low-level laser therapy roles on cisplatin-induced peripheral neuropathy should be investigated in vivo, and the relationship between quercetin and low-level laser therapy should be molecular.

ABSTRACT

PURPOSE: To explore a minimally invasive trans-canal endoscopic facial nerve decompression for traumatic facial nerve palsy and compare it with microscopic facial nerve decompression.

METHODS: 35 and 38 patients underwent endoscopic and microscopic facial nerve decompression, respectively, for traumatic facial nerve palsy. Onset of symptoms, type of temporal bone fracture, day of surgical intervention following trauma, ossicular chain status and nature of insult to facial nerve were observed. Time period for recovery (House Brackmann grade ≤ 3), long term recovery rates, pre- and post-operative hearing status, surgical time and post-operative pain were compared between groups.

RESULTS: Maximum patients in endoscopic and microscopic groups (77.1% and 76.3%, respectively) had acute onset of symptoms. 57.1% (20/35) had longitudinal, 17.1% (6/35) had transverse and 25.7% (9/35) had mixed fractures in endoscopic group. In the microscopic group, 57.9% (22/38) had longitudinal, 18.4% (7/38) had transverse and 23.7% (9/38) had mixed fractures. The mean (± S.D.) post-operative air-bone gap in endoscopic and microscopic group were 16.47 ± 4.5 dB and 19.4 ± 5.2 dB, respectively, which was statistically significant. The mean (± S.D.) time period for recovery of endoscopic and microscopic groups were 14.4 ± 5 days and 22.5 ± 7 days, respectively (p value < 0.05). The difference in post-operative pain between the two groups was also statistically significant. The difference in long term recovery rates was not statistically significant (p > 0.05).

CONCLUSIONS: Endoscopic facial nerve decompression results in early recovery, less post-operative pain and better post-operative air-bone gap closure when compared to conventional microscopic technique.

ABSTRACT

BACKGROUND: To quantify the relationship between [18F]FDG uptake of the primary tumour measured by PET-imaging with immunohistochemical (IHC) expression of ER, PR, HER2, Ki-67, and clinical subtypes based on these markers in breast cancer patients.

METHODS: PubMed and Embase were searched for studies that compared SUV_max between breast cancer patients negative and positive for IHC expression of ER, PR, HER2, Ki-67, and clinical subtypes based on these markers. Two reviewers independently screened the studies and extracted the data. Standardized mean differences (SMD) and 95% confidence intervals (CIs) were estimated by using DerSimonian-Laird random-effects models. P values less than or equal to 5% indicated statistically significant results.

RESULTS: Fifty studies were included in the final analysis. SUV_max is significantly higher in ER-negative (31 studies, SMD 0.66, 0.56-0.77, P < 0.0001), PR-negative (30 studies, SMD 0.56; 0.40-0.71, P < 0.0001), HER2-positive (32 studies, SMD – 0.29, – 0.49 to – 0.10, P = 0.0043) or Ki-67-positive (19 studies, SMD – 0.77; – 0.93 to – 0.61, P < 0.0001) primary tumours compared to their counterparts. The majority of clinical subtypes were either luminal A (LA), luminal B (LB), HER2-positive or triple negative breast cancer (TNBC). LA is associated with significantly lower SUV_max compared to LB (11 studies, SMD – 0.49, – 0.68 to – 0.31, P = 0.0001), HER2-positive (15 studies, SMD – 0.91, – 1.21 to – 0.61, P < 0.0001) and TNBC (17 studies, SMD – 1.21, – 1.57 to – 0.85, P < 0.0001); and LB showed significantly lower uptake compared to TNBC (10 studies, SMD – 0.77, – 1.05 to – 0.49, P = 0.0002). Differences in SUV_max between LB and HER2-positive (9 studies, SMD – 0.32, – 0.88 to 0.24, P = 0.2244), and HER2-positive and TNBC (17 studies, SMD – 0.29, – 0.61 to 0.02, P = 0.0667) are not significant.

CONCLUSION: Primary tumour SUV_max is significantly higher in ER-negative, PR-negative, HER2-positive and Ki-67-positive breast cancer patients. Luminal tumours have the lowest and TNBC tumours the highest SUV_max. HER2 overexpression has an intermediate effect.
