Socio-Demographic Factors, Clinical Characteristics and Maternal Prognosis of Hypertensive Disorders in Pregnancy at Panzi General Referral Hospital

Background: Hypertensive disease in pregnancy is an important cause of morbidity, long-term disability, and maternal and neonatal mortality. The aim is to determine the socio-demographic characteristics and maternal prognosis of these women with Hypertension during pregnancy. Material and Method: We conducted a cross-sectional study, we interview patients and after discussion we transcripts in a database in Excel software before analysis with SPSS version 20.0 and Stata 14.0 The qualitative variables have been summarised by the Percentage and the quantitative variables will be summarised by Means and Standard Deviation. The associations of the variables were calculated by Pearson’s chi-square test with a significance level set at a p-value Result: The average age of the patients was 30.33 ± 7.020 years, 92.1% were married, 79.8% lived in urban areas, most of the patients were overweight (43%), 92.1% of them had monofetal pregnancies, 36% were multiparous, 34.2% had a previous history of preeclampsia in pregnancy and 14% were known to have hypertension. Pre-eclampsia was the most frequent form of hypertension in pregnancy with 73.68% of cases and represents 84.8% of severe forms of hypertension in pregnancy, 53.4% of the patients delivered vaginally. Eclampsia was the most frequent complication in our patients with 31.7% frequency and among the socio-demographic parameters, age and body mass index were significantly associated with maternal complications. Conclusion: Maternal age and body mass index are important socio-demographic factors associated with the occurrence of maternal complications in women with hypertensive disorders in pregnancy.

The Psychological Experience of the Nursing Staff of the Medical Oncology Department in Cameroon: Case of the YaoundéGeneral Hospital

Background: The world of cancer care is an emotional place, given the severity of the disease being treated, the heavy workload, the suffering of patients, and the high number of deaths. The nursing staff who work there may be exposed to constant stress from these factors. This study aimed to explore the psychological experience of the nursing staff of the Medical Oncology Department of the Yaoundé General Hospital. Methods: We carried out a cross-sectional study, in June 2017, involving the nursing staff of the Medical Oncology Department of the Yaoundé General Hospital. Results: Sixteen out of 18 nurses were interviewed. All had worked in at least one other department prior to Oncology. The number of years of experience in Oncology ranged from less than one year to 13 years. The choice of the Oncology department was involuntary for 100% of the staff;of these, 62% had intentions of changing departments. Twenty-five percent had applied for a change of department, which was unsuccessful. Stress was expressed by 94% of the staff;93% thought that there was a solution to the stress experienced on a daily basis in the Oncology department. The main solutions proposed to manage this stress were: support for the staff, provision of work materials, and staff training. Conclusion: The nursing staff of the Medical Oncology Department of the Yaoundé General Hospital experiences a high level of stress and are in need of solutions.

Assessment of Acute Poisoning Cases in Emergency Department of the Provincial General Reference Hospital in Bukavu, DR-Congo

Background: Acute intoxications result from intentionally or accidentally taking a relatively significant amount of a chemical substance which triggers disturbances in the level of psychophysiological functions, the complications of which may lead to mental disorders, physical causalities, and death. Any acute intoxication mostly requires emergency care. Objective: To highlight the prevalence, history, clinical features, emergency treatment, and prediction of acute intoxication cases referred to the emergency services at the Provincial General Reference Hospital in Bukavu, DR-Congo. Methods: A retrospective cross-sectional study was conducted from January 2021 to October 2022 based on an analysis of patients’ medical files. Triage was performed among all-type of patient files recorded in the computerized hospital database Ebale-Sante to sort cases of intoxication. Results: During the observational period, 3966 emergency admissions were counted, of which 321 (8.09%) patients were identified as having acute intoxication. Among these, 100 files that containing sufficient information fit the quality criteria for this study’s analysis. The victims were infants, adolescents and adults aged 1 - 45 years, and 52% were female and 48% were male. Most cases were accidental and, occurred at home, and the victims were driven to the hospital within 2 - 24 hours. The substances consumed included household products, drugs, and herbs. Resuscitation care, antidotes and supportive symptomatic medications ensured that 85% were healed and 10% experienced sequelae;however, 5% died. Conclusion: Acute intoxication occurs in infants mostly accidentally though the ingestion of household products and medicines. Furthermore, suicide cases may occur in traumatized adolescents and discordant couples. People should be informed about how to store hazardous products (e.g.: drugs, household products and pesticides), which should not be available to children, to avoid unintentional poisoning. Special training in clinical toxicology is required to reduce treatment failure.

Prevalence of Uropathogenic Escherichia coli among Adult Male Patients 40 Years and above with Haematuria and Impaired Kidney Attending General Hospitals in Benue State

Haematuria is the presence of red blood cells in urine. It is most often caused by urinary tract infections of which Escherichia coli is frequently implicated. Impairment of kidney functions could occur as a result of infection or other complications of the kidney. The aim of the study was to determine the prevalence of uropathogenic Escherichia coli among adult male patients with haematuria and impaired kidneys attending a general hospital in Benue state. Three hundred and sixty-eight (368) samples of urine were collected from 368 male patients (≥ 40 years) attending the 23 general hospitals in Benue state. Each of the urine samples was divided into two parts for haematuria and isolation and identification of Escherichia coli. Blood samples (368) were also collected from the patients and used for quantitative determination of creatinine and estimation of glomerular filtration rate. The presence of haematuria was 45.1% and ranges from 12.5% to 100%. Prevalence of haematuria with respect to age shows that patients within the age group of 90 - 99 years had the highest rate (100%) and the least were those within the ages of 40 - 49 years (20.0%). Isolation rate of uropathogenic Escherichia coli was 16.3% and ranged from 6.3 to 37.5%. Patients within the age group of 90 - 99 years had the highest elevated impaired renal function of 4 (80%), followed by patients within the ages of 80 - 89 years [17 (77.3%)] and the lowest were those within the ages of 40 - 49 [6 (10.0%)]. The overall presence of haematuria in the patients was high (45.1%) with similar high Escherichia coli isolation rate and impaired renal function which could mean that acute or chronic kidney disease may set in.

Frequency of Cervix Dysplasia in Women with Prolapsed Uterus: Cross-Sectional Descriptive Study at Panzi General Referral Hospital

Introduction: According to the WHO (January 7, 2022), cervical cancer is the second leading cause of cancer death worldwide among women of childbearing age. However, cervical cancer is highly preventable and treatable due to its well-known disease history which goes through several detectable pre-cancerous phases with available treatments. There are very few data on the prevalence of dysplastic lesions of the cervix in the Democratic Republic of the Congo. Panzi General Referral Hospital is a care center for women with genital prolapse, and our study aimed to determine the prevalence of dysplastic lesions of the cervix in this particular population. Methodology: This is a cross-sectional study of all women aged ≥ 18 years who consulted at the HGR Panzi from September 01 to December 31, 2022, diagnosed with uterine prolapse and who consented to the study. Results: The mean (±SD) age of the patients was 47.44 (±14.42) years and the majority (67.7%) of them were aged 40 and over. For all of the respondents, the Pap smear was normal in 62.6% and inflammatory in 2% of cases, while cytological abnormalities, which were found in 35.4% of cases, including 12.1% of lesions high-grade dysplastic (HSIL), i.e. 12 out of a total of 99 women examined. Conclusion: Women with uterine prolapse are twice as likely to develop dysplastic lesions as the general female population. A screening and management program for these lesions is essential in our preoperative protocol at the HGR Panzi and at the national level in general.

Suicide Attempts in a General Hospital: A Case-Control

Objective: This study aims is to conduct a comparative analysis of the clinical and sociodemographic profiles of individuals referred to Consultation-Liaison Psychiatry (CLP) at a tertiary general hospital, specifically focusing on those seeking assistance due to suicide attempts (TS) versus CLP requests for other reasons (non-TS) between the years 2010 and 2020. Additionally, we aim to assess factors associated with suicide attempts. Method: This retrospective controlled study involves a thorough examination of medical records encompassing 3913 patients who received CLP services at the Hospital de Base (HB) and the Children and Maternity Hospital (HCM) of São José do Rio Preto Medical School Foundation (Funfarme) from June 2010 to June 2020. The patient cohort is categorized into two groups: those with requests for SA (n = 677) and those with requests for other reasons. Results: In the SA group, as opposed to the non SA group, statistically significant differences were observed for gender (predominantly female), employment status (employed), marital status (single), and age (younger). Notably, a higher prevalence of psychiatric antecedents (88.7%, n = 555 vs. 73.6% n = 2018) was found in the SA group, indicating a significant association. The frequency of SA requests remained stable over the years. Among the SA group, mood disorders were the most prevalent (39%, n = 372), followed by disorders related to substance use (21.2%, n = 202), and personality disorders (16%, n = 152). A history of previous suicide attempts emerged as a crucial factor for the recurrence of SA (p-value ≤ 0.001). Exogenous intoxication emerged as the most frequently employed method in attempts (79.6%, n = 539), particularly prevalent among patients diagnosed with mood disorders (41%, n = 314). A significant association was observed between the method of attempt and the nosological psychiatric diagnosis (χ2 = 42.277;p ≤ 0.001). Regarding outcomes, the majority of patients were referred for outpatient follow-up (23%, n = 336) in specialized mental health services or at the Primary Healthcare Unit, highlighting the general hospital’s pivotal role in integrating patients into the broader healthcare network. Conclusion: Variables such as gender (female), age group (young adults), and psychiatric history exhibited stronger associations with suicide attempts compared to the group assisted by CLP for other reasons. Furthermore, a noteworthy correlation between the method employed and the psychiatric diagnosis was identified.

Immuno-Histochemical Profile of Breast Cancers at the General Hospital of Douala-Cameroon

Introduction: The aim of the study was to describe the immunohistochemical aspects of breast cancers at Douala General Hospital, Cameroon. Methodology: This was a descriptive study with retrospective data collection, conducted from January 1st 2010 and December 31st 2019. It was focused on histologically proven breast cancers followed up at Douala General Hospital. Results: We collected 285 cases of breast cancer, all female, representing an annual frequency of 28.5 cases. The mean age of the patients was 48 ± 13 years. The most frequent histological form was infiltrating ductal carcinoma (83.9%), with grade II predominating (38.6%). Immunohistochemical analyses were performed on 89 patients (31.23%). The triple-negative subtype was the most common class (35.95%), followed by Luminal A (32.60);Human Epidermal Receptor 2-class and Luminal B tumors were observed at a frequency of 13.48% each. Treatment consisted mainly of surgery (78.60%) combined with chemotherapy (65.97%) and/or radiotherapy (63.16%). Hormonal treatment was used in only 10.18% of patients. Targeted therapy was exceptional (4%). Conclusion: Triple-negative phenotype is the most common. However, potentially hormone-sensitive tumors account for almost half of all patients, who are relatively young. Individualized treatments are rare. It is important to systematize these analyses for all breast cancers, with a view to appropriate management in our environment.

A qualitative study on nurses'reactions to inpatient suicide in a general hospital

Aims:To explore the impact of inpatient suicides on nurses working in front-line,the patterns of regulation and their needs for support.Methods:Data were collected through purposive sampling by conducting semi-structured and individual in-depth interviews in a tertiary referral hospital in China.Colaizzi's sevenstep phenomenological method was simultaneously used by two interviewers.Results:Reactions to inpatient suicides revealed three central themes:(1)inpatients were highly likely to commit suicide,(2)inpatient suicide was difficult to prevent,and(3)nurses lacked the necessary suicide prevention skills.Psychological responses mainly included shock and panic,self-accusation or guilt,sense of fear,and frustration.The impacts on practice were stress,excessive vigilance,and burnout.Avoidance and sharing of feelings played key roles in the regulation patterns of nurses.Conclusions:Nurses who experienced inpatient suicide became stressed.Effective interventions must be implemented to improve the coping mechanisms of nurses against the negative consequences of inpatient suicide.The findings of this study will allow administrators to gain insight into the impacts of inpatient suicides on nurses in general hospitals.Such information can be used to develop effective strategies and provide individual support and ongoing education.Consequently,nurses will acquire suicide prevention skills and help patients achieve swift recovery.

Profile of Pregnant Women and Success of the Uterine Test on a Uni or Bi-Scar Uterus at the Maternity Ward of Panzi Hospital, in the Democratic Republic of the Congo

Introduction: Trial of labor after a previous cesarean section (TOLAC) is a method that requires strict monitoring to decrease the cesarean section (CS) rate and improve the maternal and neonatal prognosis. The objective is to determine the profile and outcome of patients with one and two previous CSs who performed TOLAC at Panzi General Referral Hospital. Methodology: This is a cross-sectional study with a prospective collection of data of 111 patients with one and two previous CSs at Panzi Hospital from January 2021 to August 2022. Statistical Package for the Social Sciences SPSS version 23 software was used to analyze the collected data. The percentages of categorical variables were summarized in a frequency table. The mean or median with standard deviation was used to summarize quantitative variables. Results: The overall success rate of the TOLAC was 64%, with 63.8% following one previous CS and 64.3% following two CSs. The mean age of the patients was 27.09 years, with an age range of 25 - 34 years. They were mostly pauciparous (52.2%), married (88.3%), with a high school education (60.4%). The inter-delivery interval > 18 months was noted (64.1%) and overweight in 63.9%. More than three antenatal consultations were performed (58.6%). We found a mean gestational age of 38 (34 - 41) weeks. The perinatal mortality rate was 0.9%. However, we did not record any cases of maternal mortality during the study period. Conclusion: TOLAC after one and two previous CS is implemented in the maternity Unit of Panzi Hospital for well-selected patients. In addition, the success rate is similar after TOLAC with an acceptable maternal-neonatal prognosis.

A survey on 564 cases of inpatients with anxiety and depression in general hospitals in 2015

Objective: To understand the prevalence of anxiety and depression in medical patients in general hospitals and find out main influencing factors. Methods: According to the inclusion criteria, a total of 564 inpatients from the Third Affiliated Hospital of Inner Mongolia Medical University were selected during January to June of 2015. Patients were assessed for anxiety and/or depression by use of Hospital Anxiety and Depression Scale (HADS), Hamilton Anxiety Scale (HAMAS) and Hamilton Depression Scale (HAMDS). Meanwhile, final diagnosis was made on the basis of diagnostic criteria listed in Diagnostic and Statistical Manual of Mental Disorders - Fourth Edition (DSM-IV). Results: In different departments, the positive rate (HADS ≥ 8) was the highest in Department of Oncology (45.42%), and the lowest in Department of Gastroenterology (16.05%). After assessment with the help of HAMD and HAMA, the prevalence of anxiety/depression was the highest in Department of Oncology (46.43%), and the lowest in Department of Gastroenterology (16.05%). There was no statistical significance in diagnostic results acquired from HAMD and HAMA (p = .071). Two types of diagnostic methods were highly consistent (κ = 0.852, p = .000). Inpatients aged from 40 to 59 years, with junior high school education or below, very tiring work, poor marital status (separated, divorced, widowed), unharmonious family, low personal income, completely self-paying and family history of anxiety and depression, currently unable to take care of themselves were more prone to anxiety and depression (p < .05). Conclusions: The prevalence of anxiety and depression in medical patients in general hospitals is high due to many influencing factors. It is necessary to establish an effective diagnosis and treatment system for anxiety and depression, in order to make patients easy to receive an early and comprehensive treatment and improve their life quality.

Study of Sound Environment Influenced by the Crowd in Waiting Areas in General Hospitals

In this study,the crowd has been investigated and analyzed in waiting areas in large general hospitals in China in order to find the rules the variations of sound environment with the change of crowd. The field investigation,questionnaire,field-testing and computer simulation have been adopted. The results show that: the social /demographic characteristics of staff and patients are not significantly related to the satisfaction evaluation of sound environment; there is a significant correlation between the population density and LAeq of the background noise in waiting areas; when population density is 0,the LAeq of background noise is not 0 in waiting areas; the loudspeaker should be set in the waiting areas. Loudspeaker arrangements should be integrated into the ceiling lamp or construct facilities along the depth direction of the layout,and the two adjacent speakers recommended distance should be controlled at about 4 m. If the population density is controlled in the reasonable range,and sound absorption,noise reduction processing and electronic queuing system are adopted,sound environment of waiting areas will be built with noise interference relatively small in different population densities.

Characteristics of and management strategies for 54 suicidal inpatients in a general hospital

Objective： The aim of this study was to explore the characteristics of and preventive management strategies for suicidal inpatients in a general hospital.Methods： A total of 54 suicide victims were drawn from a patient safety adverse event network reporting system during hospitalization in a general hospital from November 2008 to January 2017.Results： Subjects who committed suicide in the general hospital were women and those who suffered from malignant neoplasms during general hospital treatment. Furthermore, most of the patients who committed suicide used more violent suicide methods. The most common and lethal means was jumping from heights at the windowsill.Conclusions： It is concluded that management straties for suicide prevention can be provided from the aspects of patients, medical staff and the hospital environment. It is not only urgent but also feasible to reduce the suicide rate of inpatients and further improve hospital safety management.

Magnetic Resonance Imaging of Osteo-Articular System at the Douala General Hospital

Objectives: Osteoarticular pathology has benefited greatly from MRI. This modality was only recently introduced in our country and its implantation is still rare. The objective of this study was to evaluate the practice of MRI of osteoarticular system in Douala General Hospital. Method: It was a cross-sectional descriptive study during a five-month period from May to September 2017 involving all patients referred to the Imaging Department of the Douala General Hospital for osteoarticular MRI. All the patients were scanned using an open-sided mid-field MRI APERTO LUCENT (0.4 T) using axial, sagittal and coronal slices in T1-weighted, T2-weighted proton density. T1 gadolinium or water-fat saturation (WFS) slices were obtained after injection of a contrast agent (Dotarem). Collected data were analyzed using SPSS v20 and Microsoft Excel 2010 softwares. Results: 34 patients were enrolled in this study;osteoarticular MRI accounted for 12% of the activity behind MRI of the spine (40.4%) and the brain (42.5%). The mean age of patients was 37.6 ± 13.1 years with extremes between 6 and 61 years. There was male predominance with a sex ratio of 1.83. Trauma (44.2%) and pain (42.1%) were the most common indications. MRI of the lower limb (85.3%) and more particularly of the knee (68.9%) was more frequently performed than that of the upper limb (14.7%). Orthopedic surgeons (38.2%) and rheumatologists (26.5%) were the main referral physician. 73.5% of request’s forms did not conform to the eight compliance criteria according to the recommendations of French National Agency for Accreditation and Health Evaluation. Most of the examinations (94.1%) were performed without the injection of contrast agent (Dotarem). 97% of MRI was pathological. Traumatic pathologies (39.4%) were most frequent and concerned the knee (27.3%) and the ankle/feet (12.1%), followed by the degenerative pathologies (21.2%) which concerned the knee (18.2%) and hip joints (3%), inflammatory pathologies (12.1%) reaching the shoulder (9.1%) and wrist/hand (3%) while tumoral pathologies (6%) were reaching the knee (3%) and the leg (3%). Conclusion: The MRI of the osteoarticular system is quite common, ranking third after the MRI of the spine and the brain. This study showed that MRI has a significative impact on diagnosis of osteoarticular diseases whit a concordance of 97% with clinic.

Attitudes of General Hospital Staff towards Persons with Mental Illness: Associations between Place of Training, Ethnicity, and Type of Profession

Objective: Persons with mental illnesses (PMI) commonly report encountering discriminatory attitudes and behaviours by Health Care Professionals (HCPs) involved in their care. Such stigmatising attitudes and behaviours may affect recovery rates and erode quality of care provided by these HCPs. We assess attitudes of HCPs towards PMI in a tertiary general hospital in Singapore. Methods: An anonymised online questionnaire was sent to HCPs working in the hospital. Attitudes were assessed using the Opening Minds Stigma Scale for Healthcare Professionals (OMS-HC), with responses rated on a 3-point Likert scale. Results: Doctors and Chinese staff trained locally were significantly more likely to feel more comfortable treating persons with physical than psychiatric problems, whereas Indian staff were less likely to express such reservations. HCPs generally accepted physical complaints at face value, while nurses tended to adopt critical attitudes toward patients and negatively perceived the utility of psychiatric treatment. For instance, nurses were more likely to judge persons with mental illness as not trying hard enough to get better, while admitting to having difficulty feeling compassion for those with psychiatric problems. Staff who received undergraduate and postgraduate training overseas were more likely to develop favourable attitudes toward PMI. Conclusions: The study has uncovered gaps in the understanding of mental disorders and their treatment. These knowledge deficits should be rectified so as to reduce negative attitudes toward PMI.

Nurses Opinions Regarding Delirium Care in the Older General Hospital Population and in Older Cardiac Surgery Patients Specifically: A Multicentre Survey among Dutch Nurses

Background: Delirium is a high prevalent postoperative complication in older cardiac surgery patients and can have drastic consequence for the patient. Preventive interventions, diagnosis and treatment of delirium require specialized knowledge and skills. Objective: To gain insight in the current opinion and beliefs of nurses in hospitals concerning prevention, diagnosis and treatment of delirium in older hospital patients in general and specifically in older cardiac surgery patients. Methods: In a cross-sectional study from February to July 2010, we distributed a survey on beliefs on delirium care among 368 nurses in three hospitals in the Netherlands, in one hospital in all wards with older patients and in two hospitals in the cardiac surgery wards only. Results: Although in literature incidence rates up to 54.9% in cardiac surgery patients in hospitals are reported, with a response rate of 68% (250), half of the nurses believe that the incidence of delirium is not even 10%. Two thirds think that delirium in patients is preventable. Although, the Delirium Observation Scale is most often used for screening delirium, nearly all nurses do not routinely screen patients for delirium. Opinions on delirium of nurses working in cardiac surgery wards did not differ from nurses caring for older patients in other hospital wards. Conclusions: Nurses do have knowledge on delirium care, but there is a gap between the reported incidence in literature and the estimation of the occurrence of delirium by nurses. A two-way causal relationship emerges: because nurses underestimate the occurrence, they do not screen patients on a routine basis. And because they do not screen patients on a routine basis they underestimate the incidence.
