Objective: To review the effect of the COVID-19 pandemic on the presentation of Cervical cancer. Design/ Setting: Retrospective study involving the Regional Cancer Centres in the M62 Group. Methods: Data was collected for two equal time periods. All cervical cancers were included and FIGO 2018 staging was used for the data collection. P values were calculated using binomial hypothesis test for the difference in staging. Time from symptoms to diagnosis was assessed using a normal distribution test. All other calculations were performed using chi-squared test. Statistical significance was considered if p values were <0.05. Main outcome measures: Histology, stage at diagnosis, date of onset of symptoms, investigation and type of treatment. Results: A total of 406 cases of cervical cancer were reviewed; 233 from May – October 2019 (pre-COVID) and 173 between May – October 2020 (post COVID); representing a significant reduction in new cervical cancer diagnoses of 25% post COVID (p<0.001) There was a 42% increase in the delay from start of symptoms to diagnosis Post COVID. Pre COVID, 27% of patients presented with Stage 3 or 4 disease, whilst during COVID this was 38%; statistically significant (p <0.001). When we evaluated the treatments received between the two time periods, this was also statistically significant (chi-squared, p=0.0005). Conclusions: This study has demonstrated a statistically significant increase in the stage of cervical cancer at diagnosis and a change in treatment for cervical cancer following the onset of COVID-19. The implications of this are discussed.

Introduction:Cell division cycle protein 6 (CDC6) plays critical roles in DNA replication and carcinogenesis. The biological significance of the CDC6 G1321A polymorphism (V441I, rs13706) on cervical carcinogenesis is still unknown. Here, we examined the potential influence of this polymorphism on cell proliferation and the individual's susceptibility to cervical cancer.Methods:We genotyped the CDC6 G1321A polymorphism in 87 cervical cancer cases and 110 healthy female subjects. Unconditional logistic regression analysis was used to estimate the association between the genotypes and the risk of cervical cancer. The BrdU incorporation assay was applied to analyze the effect of this polymorphism on cell proliferation.Results:Compared with the GG homozygotes, the cervical cancer risk was significantly reduced in the individuals with the heterozygous AG genotype (odds ratio [OR], 0.53; 95% confidence interval [CI], 0.28-0.98; P = 0.042) or the homozygous AA genotype (OR, 0.29; 95% CI, 0.09-0.89; P = 0.030). Further stratified analyses showed that the decreased risk of cervical cancer was more evident among younger subjects (≤44 years old) with the AG or AA genotypes (OR, 0.44; 95% CI, 0.21-0.92; P = 0.029 and OR, 0.12; 95% CI, 0.03-0.61; P = 0.010, respectively). The BrdU incorporation assay showed that 293T cells transfected with CDC6-441I (1321A) had a lower proliferation rate in comparison with those transfected with CDC6-441V (1321G), although the difference did not reach statistical significance at the 0.05 level.Conclusions:The CDC6 G1321A polymorphism may contribute to the risk of cervical cancer. Further studies with more subjects and in diverse ethnic populations are necessary to confirm the general validity of our findings.

The assessment of thermal stress stimuli in Poland was based on the Universal Thermal Climate Index (UTCI). Daily values of UTCI at 24 stations selected to represent the whole area of Poland at 12:00 UTC were calculated over the period 1951-2018. Various UTCI characteristics, i.e., spatial averages of daily, monthly and annual values, daily spatial contrasts (i.e., the difference between daily highest and lowest UTCI values) were defined in each of 8 bioclimatic regions of Poland. Ten-year trends for UTCI and spatial contrast values were counted and their statistical significance was analysed. A statistically significant increase in UTCI values was found in all the regions of Poland. However, contrasts in thermal stress both for Poland as a whole and in most of the regions decreased significantly, especially in the north-east of Poland, the country’s coldest region. This indicates a reduction in the stimuli of thermal environment in Poland and in most of the individual regions.

Purpose:Radiotherapy with concurrent cisplatinum-based chemotherapy became a standard recommendation for the management of advanced cervical cancer in 1999. We reviewed our experience with this approach to determine the impact on patient outcomes.Methods:A retrospective review of all cervical cancer patients treated with curative intent using radical radiotherapy ± chemotherapy from 1992 to 2005 was performed. Survival and relapse rates were analyzed using the Kaplan-Meier method and were compared using the log-rank test.Results:During this period, 224 treated patients were identified: 153 (68%) were treated between 1992 and 1999 (group 1) and 71 (32%) were treated after 1999 (group 2). The median age was 53 and 55 years with a median follow-up of 49 and 34 months for groups 1 and 2, respectively. Stage classification and histological diagnosis were similar for both groups. Treatment usually consisted of external beam pelvic radiotherapy (40-45 Gy in 20-25 fractions) followed by low-dose rate brachytherapy (35-40 Gy to point A). Chemotherapy consisted of weekly intravenous cisplatinum (40 mg/m2) given concurrently with pelvic radiation. The proportion of patients receiving chemotherapy increased significantly after 1999, 12% in group 1 compared with 79% in group 2 (P < 0.01). The 5-year overall survival (OS) and progression-free survival (PFS) rates were 53% and 54% for group 1 and 64% and 67% for group 2. The improvement in PFS for group 2 approached statistical significance (P = 0.06), but the difference in OS did not.Conclusions:There has been a significant increase in the use of concurrent chemoradiation for cervical cancer treatment after 1999, and this seems to have led to higher rates of PFS and OS, although these have yet to achieve statistical significance.

AbstractPediatric body dysmorphic disorder (BDD) is challenging to treat. This study aimed to establish the prevalence of insomnia in youth with BDD and explore its impact on clinical outcomes. Sixty-six children and adolescents with BDD consecutively referred to a specialist clinic completed a range of clinical measures, including the Yale-Brown Obsessive–Compulsive Scale Modified for BDD-Adolescent Version (BDD-YBOCS-A), and the Insomnia Severity Index (ISI). Patients with clinical insomnia (ISI score ≥ 9) were compared to the rest of the sample on socio-demographic and clinical features. Fifty-six patients who received multimodal treatment were re-assessed post-treatment. A mixed-model ANOVA was performed to compare treatment outcomes between the insomnia vs. no insomnia groups, and Chi-squared tests were used to compare response and remission rates. According to the ISI, 48% of the sample qualified as having insomnia at baseline. These participants showed significantly higher self-reported BDD symptom severity, more depressive symptoms, and more functional impairment in daily activities. Patients with insomnia improved less on the BDD-YBOCS-A than those without insomnia, although the difference did not reach statistical significance. The rates of responders and remitters were lower in the insomnia group, compared to the non-insomnia group. Insomnia is prevalent in pediatric BDD, and is associated with more severe psychopathology and worse functioning in daily activities. Furthermore, youth experiencing BDD and insomnia may benefit from multimodal treatment to a lesser extent than those without insomnia. If these results are replicated in larger samples, treatment refinements for pediatric BDD could include specific modules to directly target insomnia.

AIM: to compare multiparametric endorectal ultrasound (ERUS) and enhanced imaging colonoscopy in the diagnosis of early colorectal cancer.PATIENTS AND METHODS: the study included 78 patients with epithelial rectal tumor. All the patients underwent multiparametric ERUS and colonoscopy with examination by narrow beam imaging (NBI) at optical magnification. All the patients were operated.RESULTS: a morphological examination removed specimens revealed adenomas in 48 cases, in 19 specimens – adenocarcinomas in situ and T1, and in 11 specimens – adenocarcinomas with invasion of the muscle layer or deeper. When calculating the accuracy indicators of diagnostic methods for groups of patients with adenoma, Tis-T1 adenocarcinoma, and T2-T3 adenocarcinoma, the difference in the sensitivity and specificity of the methods in none of the presented groups did not reach the level of statistical significance (p>0.05).ROC analysis showed that ultrasound has a prognostic value comparable to colonoscopy. The area difference was 0.013 (p=0.85).CONCLUSION: endoscopy and ultrasound have similar value in the diagnosis of malignant transformation of rectal adenomas.

Background: Shoulder-hand syndrome (SHS) refers to a syndrome causing sudden edema, shoulder pain and limited hand function. Qingpeng ointment, a kind of Tibetan medicine, can reduce swelling, relieve pain, tonify stagnation and clear the meridians, which is consistent with the pathological mechanism of SHS after stroke. Therefore, if clinical trials can be used to explore the effectiveness of Qingpeng ointment for treatment of poststroke SHS and promote its application in clinical medicine, this is of specific significance for the treatment of poststroke SHS. Objective: To investigate the clinical efficacy and safety of Qingpeng ointment in the treatment of poststroke SHS. To provide an objective basis for a better therapeutic treatment for poststroke SHS． Method: A prospective, randomized, controlled study was conducted. This study recruited 120 patients with poststroke SHS who met the inclusion criteria. They were randomized into the treatment group and the control group, with 60 patients allocated to each group. The treatment group received routine medical treatment and rehabilitative care after using the Qingpeng ointment, while the patients in the control group received only routine treatment without the ointment. All patients received clinical assessment with the Visual Analogue Scale (VAS), measurement of the range of motion (ROM) of the upper-limb joints, the Fugl-Meyer Assessment of Upper Extremity (FMA-U) and the Modified Barthel Index Score (MBI) before and after the whole treatment. Results: After 4 weeks of treatment, the VAS scores of both groups were decreased significantly (P＜0.05), and the difference between the two groups was statistically significant (P < 0.05). There is no statistical significance for the difference between the treatment group and control group in terms of the FMA-U and MBI scores and the forward bend, backward, outstretch, external rotation and pronation angles after treatment. The increases in the values of VAS, FMA-M and MBI in the treatment group were greater than those in the control group, and the difference was statistically significant (P < 0.05). The increases in the values of the forward bend, outreach and external rotation angles in the treatment group were greater than those in the control group, and the difference was statistically significant (P < 0.05). Conclusion: The treatment group showed better results than the control group in terms of the relief of pain symptoms, the improvement of motor function and the improvement of the activities of daily living for patients with shoulder-hand syndrome after cerebral hemorrhage. Qingpeng ointment is effective and safe in treating poststroke SHS.

Mandibular Retrognathism

In this study we evaluated whether single nucleotide polymorphisms (SNPs) in the genes encoding PTH, VDR, CYP24A1, and CYP27B1 were associated with mandibular retrognathism (MR). Samples from biologically-unrelated Brazilian patients receiving orthodontic treatment were included in this study. Pre-orthodontic lateral cephalograms were used to determine the phenotype. Patients with a retrognathic mandible were selected as cases and those with an orthognathic mandible were selected as controls. Genomic DNA was used for genotyping analysis of SNPs in PTH (rs694, rs6256, and rs307247), VDR (rs7975232), CYP24A1 (rs464653), and CYP27B1 (rs927650). Chi-squared or Fisher’s tests were used to compare genotype and allele distribution among groups. Haplotype analysis was performed for the SNPs in PTH. The established alpha was p < 0.05. Multifactor dimensionality reduction (MDR) was used to identify SNP–SNP interactions. A total of 48 (22 males and 26 females) MR and 43 (17 males and 26 females) controls were included. The linear mandibular and the angular measurements were statistically different between MR and controls (p < 0.05). In the genotype and allele distribution analysis, the SNPs rs694, rs307247, and rs464653 were associated with MR (p < 0.05). MDR analyses predicted the best interaction model for MR was rs694–rs927650, followed by rs307247–rs464653–rs927650. Some haplotypes in the PTH gene presented statistical significance. Our results suggest that SNPs in PTH, VDR, CYP24A1, and CYP27B1 genes are associated with the presence of mandibular retrognathism.

With the rapid development of e-commerce, whether network intelligent recommendation can attract customers has become a measure of customer retention on online shopping platforms. In the literature about network intelligent recommendation, there are few studies that consider the difference preference of customers in different time periods. This paper proposes the dynamic network intelligent hybrid recommendation algorithm distinguishing time periods (DIHR), it is a integrated novel model combined with the DEMATEL and TOPSIS method to solved the problem of network intelligent recommendation considering time periods. The proposed method makes use of the DEMATEL method for evaluating the preference relationship of customers for indexes of merchandises, and adopt the TOPSIS method combined with intuitionistic fuzzy number (IFN) for assessing and ranking the merchandises according to the indexes. We specifically introduce the calculation steps of the proposed method, and then calculate its application in the online shopping platform.

Abstract Introduction Cervical cancer and its etiopathogenesis, the age of women in whom it is diagnosed, average life expectancy, and prognosis are information widely covered in scientific reports. However, there is no coherent information regarding which regions—urban or rural—it may occur more often. This is important because the literature on the subject reports that people living in rural areas have a worse prognosis when it comes to detection, treatment, and life expectancy than city dwellers. Material and methods The subjects of the study were women and their knowledge about cervical cancer. The research was carried out using a survey directly distributed among respondents and via the Internet, portals, and discussion groups for women from Poland. Three hundred twenty-nine women took part in the study, including 164 from rural and 165 from urban areas. The collected data enabled the following: (1) an analysis of the studied groups, (2) assessment of the respondents’ knowledge about cervical cancer, and (3) comparison of women’s knowledge depending on where they live. Results The average assessment of all respondents’ knowledge was 3.59, with women living in rural areas scoring 3.18 and respondents from the city—4.01. Statistical significance (p < 0.001) between the level of knowledge and place of residence was determined. The results indicate that an increase in the level of education in the subjects significantly increases the chance of getting the correct answer. In the case of age analysis, the coefficients indicate a decrease in the chance of obtaining the correct answer in older subjects despite the fact that a statistically significant level was reached in individual questions. Conclusions Women living in rural areas have less knowledge of cervical cancer than female respondents from the city. There is a need for more awareness campaigns to provide comprehensive information about cervical cancer to women in rural areas. A holistic approach to the presented issue can solve existing difficulties and barriers to maintaining health regardless of the place of life and residence. Implication for cancer survivors They need intensive care for women’s groups most burdened with risk factors.

High Dose Melphalan

Background: High dose melphalan (HDMEL) is considered the standard conditioning regimen for autologous stem cell transplantation (ASCT) in multiple myeloma (MM) patients. Recent studies showed superiority of busulfan plus melphalan (BUMEL) compared to HDMEL as a conditioning regimen. We compared the efficacy of HDMEL and BUMEL in newly diagnosed Asian MM patients, who are often underrepresented. Methods: This is a single-center, retrospective study including MM patients who underwent ASCT after bortezomib-thalidomide-dexamethasone (VTD) triplet induction chemotherapy between January 2015 and August 2019. Result: In the end, 79 patients in the HDMEL group were compared to 31 patients in the BUMEL group. There were no differences between the two groups with regards to sex, age at ASCT, risk group, and stage. The HDMEL group showed better response to pre-transplant VTD compared to BUMEL, but after ASCT the BUMEL group showed better overall response. In terms of progression-free survival (PFS), although BUMEL showed trends towards better PFS regardless of pre-transplant status and age, the difference did not reach statistical significance. The BUMEL group more often experienced mucositis related to chemotherapy, but there was no difference between the two groups with regards to hospitalization days, cell engraftment, and infection rates. Conclusion: BUMEL conditioning deserves attention as the alternative option to HDMEL for newly diagnosed MM patients, even in the era of triplet induction chemotherapy. Specifically, patients achieving very good partial response (VGPR) or better response with triplet induction chemotherapy might benefit the most from BUMEL conditioning. Tailored conditioning regimen, based on patient’s response to induction chemotherapy and co-morbidities, can lead to better treatment outcomes.
