BACKGROUND

Cervical cancer remains to be the second leading cancer and cause of cancer-related deaths among Filipino women despite the use of the Papanicolaou screening. Latest research has shown that the human papillomavirus (HPV) is a necessary cause of cervical cancer. With major morbidity and high mortality rates associated with HPV infection and cervical cancer, several modes of primary and secondary forms of prevention have to be implemented. Among the primary modes of prevention is the administration of the preventive vaccine, which has consistently shown to decrease substantially HPV disease and cervical cancer rates in developed countries. In our country, before a successful vaccination, program is implemented, several sociocultural issues have to be addressed. Knowledge, attitude, and motivational factors are vital in determining acceptance of the vaccine. One relevant setting is exploring the willingness of mothers to get their female children vaccinated even before they become sexually active.

The aim of the study was to determine the association of the knowledge, attitude, and motivational factors of mothers on their willingness for their female children aged 9–13 years to undergo HPV vaccination at a tertiary government hospital.

This was a cross-sectional study that was carried out at a government institution.

The population consisted of 352 mothers with female children aged 9–13 years consulting the outpatient clinics at the department of obstetrics and gynecology at a tertiary government hospital.

A pretested and validated survey was given to 352 respondents. They were asked to answer a self-administered questionnaire that included sociodemographic, reproductive, sexual history variables, knowledge, and attitude, and motivational factors toward the disease and the associated vaccine.

Using the survey proportion estimation methods, the prevalence of women who were willing to enroll their daughters for HPV vaccination was 97.18% (n = 42, 95% confidence interval [CI]: 94.91 to 98.46%). It can be noted that only a third of the sample had high knowledge on the vaccine and its use 34.93% (n = 124, 95% CI: 30.25 to 39.92%). More women who reached college level (χ2: 5.67) and also those whose youngest child was between 11 and 13 years old (χ2: 8.82)-had higher knowledge scores than otherwise. Those who have an annual income of greater than or equal to P 60,000 (χ2: 16.55) and are non-Catholic (χ2: 18.77) – also appeared to have higher knowledge ratings on the questionnaire. Women who never to a few times a year attend church-related activities had higher knowledge scores compared to women who were more frequent goers (χ2: 16.33). For the attitude toward the vaccine, more mothers believed that getting the vaccine would not have an effect on a girl’s sexual activity and most agreed that they would not be viewed as bad parents. Most women also did not believe that religion would affect their willingness to vaccinate their children. There was an association in the degree of agreement between negative and positive attitudes from the Chi-square test performed (χ2: 7.44, P: 0.01). There were more agreeing responses from factors determining positive attitude and more disagreeing responses in the factors determining negative attitude. With regard to motivational factors, more women agreed that the cost was prohibitive and that they were more willing if only two doses would be required for their daughters. They were also not concerned about what other parents may think about getting the vaccine. Most answered that they were willing to follow their doctors’ recommendations and they have trust in vaccine manufacturers. Most women were also concerned that their daughters may get cervical cancer in the future. There was no difference in the proportion of agreeing responses between positive and negative motivating factors among the study participants (Z: 0.30, P: 0.79). This suggested that these factors could be important predictors of willingness to use vaccination on their children. Based on the crude odds ratios from the logistic regression, the likelihood of being willing to administer HPV vaccine to their children was almost twice as the knowledge score and scores on the positive attitude items increased, and was found to be statistically significant. At the same time, the odds of willingness increased by more than twice as the score on the negative attitude items decreased, and was also significant. There was no noted association for the other predictors of the association.

The role of knowledge and attitudes on the negative perceptions on the vaccine were important predictors of the willingness of mothers to have their female children vaccinated against HPV infection.

Background: Cervical cancer is the fourth leading cause of cancer deaths in women worldwide and second in the Philippines. However, Pap smear test, a common screening test procedure for the detection of cervical cancer, remains underutilized, contributing to the increasing incidence of cervical cancer. Women's knowledge, attitudes, and practices (KAP) must be measured to ensure good, targeted interventions; and increase screening and detection of cervical cancer cases. Objectives: The study aims to determine the KAPof women in Surallah, South Cotabato, towards Pap smear. It also aims to help the local government, college administrators, and rural health unit create programs to enhance women's KAPin the municipality. Methodology: The study used a descriptive, cross-sectional design, employing questionnaires manually distributed to determine the KAPof women in Surallah, South Cotabato. Results: The study included 375 respondents. Most know the purpose and importance of a Pap smear but are in need of better understanding of the procedure and the timing of the test. Most of the respondents also had varied reactions toward the test toward the test; some had positive attitudes, and others had negative attitudes. The respondents didn't undergo the procedure despite having a good knowledge of it. Conclusion Most respondents correctly understood the importance of the procedure but needed to learn how it was done. They also have a fair to commendable attitude towards the test. However, despite these, the respondents still practice poorly due to misconceptions and misinformation

OBJECTIVE: To investigate the effects of asperuloside on cervical cancer based on endoplasmic reticulum (ER) stress and mitochondrial pathway. METHODS: Different doses (12.5-800 µg/mL) of asperuloside were used to treat cervical cancer cell lines Hela and CaSki to calculate the half maximal inhibitory concentration (IC₅₀) of asperuloside. The cell proliferation was analyzed by clone formation assay. Cell apoptosis, intracellular reactive oxygen species (ROS) and mitochondrial membrane potential were determined by flow cytometry. The protein expressions of cleaved-caspase-3, Bcl-2, Bax, Cyt-c, cleaved-caspase-4 and glucose-regulated protein 78 (GRP78) were analyzed by Western blot. And the inhibitor of ER stress, 4-phenyl butyric acid (4-PBA) was used to treat cervical cancer cells to further verify the role of ER stress in the apoptosis of cervical cancer cells induced by asperuloside. RESULTS: Asperuloside of 325, 650, and 1300 µg/mL significantly inhibited the proliferation and promoted apoptosis of Hela and CaSki cells (P<0.01). All doses of asperuloside significantly increased intracellular ROS levels, reduced mitochondrial membrane potential, significantly reduced Bcl-2 protein expression level, and increased Bax, Cyt-c, GRP78 and cleaved-caspase-4 expressions (P<0.01). In addition, 10 mmol/L 4-PBA treatment significantly promoted cell proliferation and reduced apoptosis (P<0.05), and 650 µg/mL asperuloside could reverse 4-PBA-induced increased cell proliferation, decreased apoptosis and cleaved-caspase-3, -4 and GRP78 protein expressions (P<0.05). CONCLUSION Our study revealed the role of asperuloside in cervical cancer, suggesting that asperuloside promotes apoptosis of cervical cancer cells through ER stress-mitochondrial pathway.

Objective: To investigate the clinical characteristics of induced labor in twin pregnancy and the related factors of induced labor failure. Methods: The clinical data of twin pregnant women who underwent induced labor in Peking University Third Hospital from January 2016 to December 2022 were retrospectively analyzed. According to whether they had labor or not after induction, pregnant women were divided into the success group (pregnant women who had labor after induction, 72 cases) and the failure group (pregnant women who did not have labor after induction, 30 cases). Logistic regression was used to analyze the related factors of induction failure in twin pregnant women. Results: The parity and cervical Bishop score in the failure group were significantly lower than those in the success group, while the proportion of dichorionic diamniotic twins, assisted reproductive technology pregnancy and cervical Bishop score <6, postpartum hospital stay and total hospital stay in the failure group were significantly higher than those in the success group (all P<0.05). The proportion of induced labor by artificial rupture of membranes ± oxytocin intravenous infusion in the success group was 72.2% (52/72), which was significantly higher than that in the failure group (46.7%, 14/30; P=0.030). There were no significant differences between the two groups in the gestational age at delivery, the incidence of severe postpartum hemorrhage and blood transfusion, the amount of postpartum hemorrhage, the neonatal weight of two fetuses, the incidence of neonatal asphyxia, and the proportion of neonates admitted to the neonatal intensive care unit (all P>0.05). There were no severe perineal laceration and hysterectomy in all pregnant women. Multivariate logistic regression analysis showed that primipara (OR=3.064, 95%CI: 1.112-8.443; P=0.030) and cervical Bishop score <6 (OR=5.208, 95%CI: 2.008-13.508; P=0.001) were the independent risk factors for induction failure in twin pregnancy. Conclusions: Elective induction of labor in twin pregnancy is safe and feasible. It is helpful to improve the success rate of induction of labor by strictly grasping the timing and indications of termination of pregnancy, choosing the appropriate method of induction according to the condition of the cervix, and actively promoting cervical ripening .

Background and Objective: Brachytherapy is the only demonstrated technique of delivering the high radiation dose required to control cervical cancer (>80 Gray [Gy]) without causing unwanted side effects. There is still limited data available in the Philippines regarding the anesthetic management of patients receiving intracavitary brachytherapy for cervical cancer. It is the aim of this study to present the anesthetic management of these procedures performed in a non-operating site remote from the main hospital during the first 1 ½ years of the COVID-19 pandemic. Methods: A retrospective review of 446 eligible charts was made. Data collected included demographic variables, ASA physical status classification, anesthetic technique, anesthetic agents used, oxygen supplementation device, duration of procedure, intra-procedure complication, intra-procedure pain medications, post-procedure pain medications, recovery room (RR) rescue medications, time to fulfill discharge criteria, and patient disposition. Results: Four hundred forty-six (446) anesthetic encounters involving 117 patients is presented. Charts from 46 patients were excluded as it cannot be located. Mean age of the patients was 49 years with majority having normal BMI. Spinal anesthesia (SA) was more frequently (75%) used compared to total intravenous anesthesia (TIVA). Less than 5% immediate anesthesia-related complications were recorded and all patients were discharged on the same day. Conclusion Spinal anesthesia and TIVA are safe and effective anesthetic techniques in patients with cervical cancer undergoing high dose intracavitary brachytherapy. Prospective studies to assess other aspects of their care as well as anesthesia-related long-term effects from repetitive anesthetic exposure is recommended.

Objective: To investigate the effect of hsa_circ_0000392 (circ_0000392) on the radiosensitivity of cervical cancer cells and explore its potential mechanism. Methods: Cervical cancer tissues and adjacent normal tissues of 42 patients with cervical cancer who were confirmed pathologically for the first time in Huaihe Hospital of Henan University from 2016 to 2019 were collected. According to the patients' response to radiotherapy, the cancer tissues were divided into radio-sensitive tissues and radio-resistant tissues. The expressions of circ_0000392, miR-145-5p, and CRKL in radiation-sensitive, radiation-resistant cervical cancer tissues and Hela, SiHa cells were detected by reverse transcription-quantitative real-time polymerase chain reaction (RT-qPCR) and western blot. SiRNA circ_0000392, miR-145-5p mimic, miR-145-5p inhibitor, pcDNA 3.1-CRKL and its negative control were transfected into HeLa and Siha cells, respectively. After radiation induction, the survival fraction of cells was detected by clone formation assay, apoptosis was detected by flow cytometry, and the expressions of apoptosis-related proteins Bax and Bcl-2 and ERK pathway protein p-ERK1/2 and ERK1/2 were detected by western blot. The targeting relationship between circ_0000392, miR-145-5p and CRKL was verified by dual luciferase reporter gene assay. The effect of circ_0000392 on radiotherapy sensitivity of cervical cancer in vivo was observed in the tumor formation experiment in nude mice. Results: circ_0000392 and CRKL were upregulated in radiation-resistant tissues and cancer cells of cervical cancer, while miR-145-5p was downregulated. The clone formation numbers of Hela and SiHa cells in si-circ_0000392#1+ 6 Gy group were (78.67±10.97) and (71.00±9.54), respectively, which were lower than those in si-Ctrl+ 6 Gy group [(176.00±22.27) and (158.33±17.56), respectively]. The apoptosis rates were (41.55±3.40)% and (31.41±3.29)%, respectively, which were higher than those in si-Ctrl+ 6 Gy group [(15.91±1.37)% and (13.70±1.89)%, P<0.05]. The protein expression of Bax was higher than that of si-Ctrl+ 6 Gy group, and the protein expressions of Bcl2 was lower than those of si-Ctrl+ 6 Gy group. The clone formation numbers of Hela and SiHa cells in si-circ_0000392#1+ miR-145-5p inhibitor+ 6 Gy group were (171.33±25.01) and (137.00±21.66), higher than those in si-circ_0000392#1+ inhibitor NC+ 6 Gy group [(84.67±17.79) vs (71.00±11.00), P<0.05]. The apoptosis rates were (17.41±2.58) % and (15.96±1.25) %, lower than those of si-circ_0000392 #1+ inhibitor NC+ 6 Gy [(40.29±2.92)% and (30.82±2.34)%, respectively, P<0.05]. The expression of Bax protein was lower than that of si-circ_0000392#1+ inhibitor NC+ 6 Gy group, and the expressions of Bcl2 protein were higher than those of si-circ_0000392#1+ inhibitor NC+ 6 Gy group. Circ_0000392 can target miR-145-5p, and CRKL is the downstream target gene of miR-145-5p. The clone formation numbers of Hela and SiHa cells in miR-145-5p mimic+ 6 Gy group were (74.33±10.02) and (66.00±12.17), respectively, which were lower than those of mimic NC+ 6 Gy group [(197.67±17.21) vs (157.67±11.59), respectively, P<0.05]. The apoptosis rates were (45.58±2.16)% and (32.10±3.55)%, higher than those of mimic NC+ 6 Gy group [(15.85±2.45)% and (13.99±1.69)%, respectively, P<0.05]. The expression of Bax protein was higher than that of the mimic NC+ 6 Gy mimic group, and the expression of Bcl2 protein was lower than that of the mimic NC+ 6 Gy group. The clone formation numbers of Hela and SiHa cells in miR-145-5p mimic+ pcDNA-CRKL+ 6 Gy group were (158.00±15.88) and (122.33±13.65), respectively, which were higher than those of miR-145-5p mimic+ pcDNA+ 6 Gy group [(71.33±8.02) vs (65.67±12.22), P<0.05]. The apoptosis rates were (19.50±3.45)% and (17.04±0.94)%, respectively, which were lower than those of miR-145-5p mimic+ pcDNA+ 6 Gy group [(44.33±2.36)% and (32.05±2.76)%, respectively, P<0.05]. The expression of Bax protein was lower than that of miR-145-5p mimic+ pcDNA group+ 6 Gy group, and the expression of Bcl2 protein was higher than that of miR-145-5p mimic+ pcDNA+ 6 Gy group. Sh-circ_0000392 group had smaller tumor volume and decreased tumor weight (P<0.05). The relative mRNA expression levels of circ_0000392, miR-145-5p and CRKL and the relative protein expression levels of CRKL, Bcl-2 and p-ERK1/2 were decreased, while the relative expression level of Bax protein was increased (P<0.05). Conclusion: Circ_0000392 could enhance the radiosensitivity of cervical cancer cells, and its mechanism may be related to the regulation of CRKL/ERK signaling pathway by targeting miR-145-5p, which provides a new reference for enhancing the radiosensitivity of cervical cancer cells.

Objective: To analyze the survival of newly diagnosed malignant tumors in cancer registration areas of Hubei Province from 2013 to 2015. Methods: From January 1, 2013 to December 31, 2015, all newly diagnosed malignant tumors were collected from cancer registration areas in Hubei Province, and patients were followed up using a combination of active and passive methods. Cancer survival was analyzed using the strs package in Stata software. Observed and expected survival were calculated using the life table and Ederer Ⅱ methods, and the difference in survival rate of patients with different sex, age, urban and rural areas and different cancer species was compared. Results: From 2013 to 2015, 83 987 new malignant tumors were diagnosed in cancer registration areas in Hubei Province, including 45 742 males (54.46%) and 38245 females (45.54%). The overall 5-year relative survival rate was 41.46%, 34.43% for men and 49.63% for women. With the increase of age, the observed survival rate and relative survival rate of patients of different genders showed a decreasing trend. The 5-year relative survival rate of patients with malignant tumors was 47.58% in urban areas and 26.58% in rural areas. The observed survival rate and relative survival rate in rural areas were significantly lower than those in urban areas. The overall 5-year relative survival rates for common malignancies were 20.61% for lung cancer, 15.36% for liver cancer, 22.89% for esophageal cancer, 34.92% for gastric cancer, and 54.87% for colorectal cancer. In addition, the 5-year relative survival rates of common malignant tumors in women were 78.65% for breast cancer and 52.55% for cervical cancer. Conclusions: In Hubei Province, the survival rate of malignant tumors is different among different genders, regions, age groups and cancer species. Prevention and treatment and health education should be strengthened for malignant tumor patients in rural areas and those with high incidence and low survival rate such as liver cancer and lung cancer, and relevant strategies should be formulated according to the gender and age distribution characteristics of different cancer species.

Cervical cancer mainly caused by human papillomavirus (HPV) infection has become a public health issue, which seriously threatens women 's health. To prevent HPV infection, the currently used prophylactic vaccines mainly induce a humoral immune response in the host, thereby generating neutralizing antibodies. In contrast, the design goal of therapeutic HPV vaccines is to induce a cell-mediated immune response in the host, primarily driven by Th1 cells, aiming to clear existing viral infections and slow down or inhibit tumor progression. Currently, several therapeutic HPV vaccines based on different mechanisms and techniques have entered clinical trials. This review will summarize the progress of these clinical trials, providing reference for the research and development of therapeutic HPV vaccines.
