BACKGROUND: The enzyme 11β-hydroxysteroid-dehydrogenase type 1 (11β-HSD1) catalyses the reactivation of intracellular cortisol. We explored the potential role of 11β-HSD1 overexpression in visceral adipose tissue (VAT) in non-alcoholic fatty liver disease (NAFLD) assessing sequential changes of enzyme expression, in hepatic and adipose tissue, and the occurrence of portal hypercortisolism in obese mice. 11β-HSD1 expression was also assessed in tissues from obese patients undergoing bariatric surgery. METHODS: Peripheral and portal corticosterone levels and liver histology were assessed in ob/ob mice at two time points (8-12 weeks of age). 11β-HSD1 tissue expression was assessed in by RT-pcr in ob/ob mice and in 49 morbidly obese patients. RESULTS: Portal corticosterone serum levels were higher in obese mice with a 26% decrease between 8 and 12 weeks of age (controls: 78.3 ± 19.7 ng/ml, 8-week-old ob/ob: 167.5 ± 14.5 ng/ml and 12-week-old ob/ob: 124.3 ± 28 ng/ml, P < 0.05). No significant differences were found in peripheral corticosterone serum levels. Expression of 11β-HSD1 was lower in the liver [-45% at 8 weeks and -35% at 12-weeks (P = 0.0001)] and highly overexpressed in VAT in obese mice, compared to controls (128-fold higher in 8-week-old ob/ob and 41-fold higher in 12-week-old ob/ob, P < 0.01). No significant differences were seen in the expression of 11β-HSD1 in subcutaneous adipose tissue. In multivariate analysis, human 11β-HSD1 expression in VAT (OR: 1.385 ± 1.010-1.910) was associated with NAFLD. CONCLUSION: Murine NAFLD is associated with portal hypercortisolism and11β-HSD1 overexpression in VAT. In humans, 11β-HSD1 VAT expression was associated with the presence of NAFLD. Thus, local corticosteroid production in VAT may contribute to NAFLD pathogenesis.

Development of cerebral malaria (CM), a severe and fatal form of clinical Plasmodium falciparum infection, results from a damaging cascade of vascular, inflammatory, and immunological host responses that leads to brain injury. Progression to CM can be modified by host genetic factors. Our case-control study in Angolan children aimed at highlighting the role of IFN (α, β) receptor 1 (IFNAR1) in progression to CM. We report a robust association between IFNAR1 and CM protection, as well as detailed studies showing analogous protection from experimental CM in Ifnar1(-/-) mice infected with P. berghei ANKA. We developed a novel cell-transfer protocol that enables spleen cell priming in the absence of disease. This led to the discovery that IFNAR1 expression in CD8(+) T cells is crucial and can abrogate resistance to experimental CM in Ifnar1(-/-) mice. Splenic CD8(+) T cells from Ifnar1(-/-) mice are functionally activated upon infection, yet are unable to mediate experimental CM development within the brain tissue. Our findings prove that IFNAR1 signaling unleashes CD8(+) T cell effector capacity, which is vital for CM, and raises the hypothesis that the cohesive role of IFNAR1 in both human and mouse CM operates through CD8(+) T cell triggering.

Counterpoint: Emergency (“Stat”) EEG in the Era of Nonconvulsive Status Epilepticus
Kenneth G. Jordan, A Schneider
2009· American Journal of Electroneurodiagnostic Technology19doi:10.1080/1086508x.2009.11079704

The most widely accepted indication for a stat EEG (stEEG) is the suspicion of nonconvulsive status epilepticus (NCSE). NCSE has been reported with surprising frequency in a wide variety of acute structural and metabolic brain injuries and significantly increases the risk of permanent brain damage and death. This risk rises and the effectiveness of treatment decreases with delays in diagnosis and increased duration of NCSE. Recent evidence confirms that more than half of NCSE patients improve with anti-seizure treatment. The emergence of NCSE as a common, dangerous, time-urgent, and treatable problem has positioned it as a target for emergency therapeutic intervention. NCSE can only be diagnosed by EEG testing, and stEEG has demonstrated value in improving NCSE management. As a result, in the near future, EEG laboratories will see increasing demands for stEEG related to NCSE. The two main obstacles to an effective stEEG program are EEG technologist coverage and electroencephalographer availability after work hours. We recommend three simple but fundamental changes in the traditional approach to stEEGs in order to overcome these obstacles: the use of EEG set-up templates by onsite personnel, easy access to EEG instruments after hours, and remote stEEG connectivity for real-time, off-site electroencephalographer interpretation.

2016· British Journal of Urology18doi:10.1111/bju.13482

OBJECTIVE: polymer-delivered, subcutaneous, leuprolide acetate (ADSC-LA), formulations suppressed serum testosterone to concentrations of ≤20 ng/dL. PATIENTS AND METHODS: Data from four open-label, fixed-dose studies were evaluated. Male patients aged 40-86 years with advanced prostatic adenocarcinoma, whom had not undergone prior androgen-deprivation therapy (ADT), were treated with a depot formulation of ADSC-LA: 7.5 mg (1-month, 120 patients), 22.5 mg (3-month, 117 patients), 30 mg (4-month, 90 patients), or 45 mg (6-month, 111 patients). Serum testosterone was sampled at screening, baseline, 2, 4, 8 h after dosing, 1, 2, 3, and 7 days, and every week until the next dose, at which time, the sampling schedule repeated until the end of study (24 weeks for 1- and 3-month formulations, 32 weeks for 4-month, and 48 weeks for the 6-month). The primary analyses were mean serum testosterone concentrations and proportion of patients who achieved concentrations of ≤20 ng/dL. RESULTS: The mean (SE) serum testosterone concentrations at the end of study were consistently ≤20 ng/dL in each study, at 6.1 (0.4), 10.1 (0.7), 12.4 (0.8), and 12.6 (2.1) ng/dL for the 1-, 3-, 4-, and 6-month formulations, respectively. A high proportion of patients (94%, 90%, 92%, 96% for the 1-, 3-, 4-, and 6-month formulations, respectively) achieved testosterone concentrations of ≤20 ng/dL within 6 weeks, and 90-97% of patients in all studies maintained concentrations of ≤20 ng/dL from weeks 6-24. CONCLUSIONS: Recent studies have shown improved outcomes in patients with prostate cancer who consistently attained a more rigorous level of testosterone suppression (≤20 ng/dL) with ADT than the historical standard (≤50 ng/dL). All doses of ADSC-LA rapidly achieved and maintained mean serum testosterone to the more rigorous target concentration of ≤20 ng/dL. These data suggest that ADSC-LA delivers equivalent testosterone suppression as achieved by surgical castration.

UNLABELLED: The objective of the study was to assess the cost of multiple sclerosis (MS) patients in Argentina categorized by disease severity using a societal perspective. METHOD: Cross-sectional study including MS patients from 21 MS centers in 12 cities of Argentina. Patients were stratified by disease severity using the expanded disability status scale (EDSS) (group 1 with EDSS score between 0 and 3; group 2 with EDSS >3 and <7; group 3 with EDSS ≥7). Direct and indirect costs were analyzed for the second quarter of 2012 from public sources and converted to US Dollars. RESULTS: 266 patients were included. Mean annual cost per MS patient was USD 36,025 (95%CI 31,985-38,068) for patients with an EDSS between 0-3; USD 40,705 (95%CI 37,199-46,300) for patients with EDSS >3 and <7, and USD 50,712 (95%CI 47,825-62,104) for patients with EDSS ≥7. CONCLUSIONS: This is the first Argentine study evaluating the costs of MS considering disease severity.

Basic Anatomy and Physiology of Sleep
Major Suzette Marie Izac
2006· American Journal of Electroneurodiagnostic Technology16doi:10.1080/1086508x.2006.11079555

This paper seeks to give a basic look at the structure and physiology of those aspects of the nervous and respiratory systems most involved with the cycles of sleep. The brain is examined from the hindbrain (the medulla and the pons) to the midbrain up through the forebrain (the diencephalon and the telencephalon). Also noted are structures that may have a role in sleep and wake cycles, such as the reticular activating system, the red nucleus, basal ganglia, pineal gland, and the like. The respiratory system's structure and physiology is discussed in broad terms. Some of the other factors involved with the generation of slow wave sleep and rapid eye movement sleep are also briefly discussed including neurotransmitters, hormones, and circadian rhythms. The origins of some of the terms used are provided to help facilitate learning.

Guidelines for Developing Multidisciplinary Treatment Plans
Deborah Galasso
1987· Psychiatric Services13doi:10.1176/ps.38.4.394

The formulation of a multidisciplinary treatment plan is important not only because it is required by federal and accreditation agencies but because it increases communication, consistency, and direction among members of the treatment team. Input from all disciplines is most effectively obtained through the multidisciplinary treatment planning conference. The author provides guidelines for formulating a plan in each of four major steps: assessment, problem identification, planning (including priorities, long- and short-term goals, and interventions), and evaluation.

Objective: The objective of this study was to examine the characteristics and utilization patterns of palliative care among lymphoma cancer patients using a large-scale representative population-based sample. Methods: Retrospective analysis was conducted on hospitalization data from the National Inpatient Sample (NIS) spanning January 2016 to December 2019. The study aimed to investigate the characteristics and disparities associated with the provision of palliative care to deceased lymphoma patients and evaluate its impact on healthcare utilization, specifically discounted hospital charges and length of stay (LOS). Multivariate linear and logistic regression analyses were performed, stratifying the data based on age, race, Charlson comorbidity index, insurance status, median household income, and hospital characteristics. The study population was classified and identified using ICD-10 codes. Results: We identified 10,323 deceased lymphoma patients from hospitalization records, among whom 52.9% (n=5,464) received palliative care during their hospital stay. Multivariate linear regression analysis demonstrated that the group receiving palliative care had significantly lower total charges, with a mean decrease of $24,269 (95% CI: $37,263 to $11,277, p &amp;lt; 0.001) compared to the group not receiving palliative care. However, there was no statistically significant difference in the adjusted length of stay between patients who received palliative care and those who did not (coefficient = -0.07 days, 95% CI = -0.69 to 0.54, p = 0.806). Multivariate logistic regression analysis indicated that patients with Black and Hispanic race had lower odds of receiving palliative care, while those admitted to larger and urban teaching hospitals had higher odds of receiving palliative care. Additionally, patients with Medicare had the lowest probability of receiving palliative care compared to other insurance groups. Conclusion: This study provides valuable insights into the utilization patterns and characteristics associated with palliative care among deceased lymphoma patients. The findings demonstrate that receiving palliative care is associated with significantly lower total charges, indicating its potential cost-saving benefits in healthcare utilization. However, no significant difference was observed in the adjusted length of stay between patients who received palliative care and those who did not. Furthermore, the study highlights disparities in access to palliative care, with Black and Hispanic patients having lower odds of receiving such care. Hospital characteristics, such as size and urban teaching status, were found to influence the likelihood of palliative care utilization. Additionally, patients with Medicare insurance had the lowest probability of receiving palliative care compared to other insurance groups. These findings underscore the need to address disparities in access to palliative care and ensure equitable provision for all lymphoma patients, irrespective of race or insurance status. Integrating palliative care into the treatment approach for lymphoma patients has the potential to optimize healthcare utilization and improve patient outcomes. Policymakers should consider these findings to enhance resource allocation and promote equitable access to palliative care services. Further research and implementation efforts are warranted to improve access and enhance the delivery of palliative care for lymphoma patients.

As new applications for the use of the Global Positioning System (GPS) on aerospace vehicles emerge, more attention is being paid to the design of the user segment, which comprises the hardware and software employed by the user to obtain navigation information from GPS. The complexity of the design of the user segment, as well as the performance demanded of the components (such as the antenna), depends on user requirements such as total navigation accuracy. Other factors, for instance the expected satellite/vehicle geometry or the accuracy of an accompanying inertial navigation system, can also affect the user segment design. The interaction between these effects, the user requirements, and the user segment design is studied. Design curves are developed which allow quick trade studies to be performed.

Background: Medical image analysis plays a crucial role in the screening, monitoring, diagnosis, and prognosis of diseases. Hepatocellular Carcinoma (HCC) often remain asymptomatic in their early stages. Timely identification and intervention are crucial to prevent the progression to decompensated liver diseases and advanced-stage HCC, minimizing morbidity and mortality. Methodology: This study examined twenty relevant research articles that met the inclusion criteria. Utilizing the PRISMA criteria, a systematic search was conducted on PubMed/MEDLINE and Google Scholar for studies on HCC screening employing Artificial Intelligence (AI) and Machine Learning (ML). The search focused on the keywords "artificial intelligence" and "hepatocellular carcinoma," with inclusion criteria specifying studies in the English language published in and after 2020. Exclusions were made for histology, animal research, and investigations conducted before 2020. Titles and abstracts were thoroughly reviewed, and any discrepancies were discussed. Results: The comprehensive review reveals the transformative impact of AI and ML on HCC screening, diagnosis, and therapy. ML models demonstrated effectiveness in early HCC diagnosis, distinguishing hepatic lesions, predicting treatment responses, and assessing recurrence risks across various techniques. Integration of mass spectrometry-based technologies, advanced imaging, and real-world data significantly improved diagnostic accuracy and clinical decision support. AI models exhibited diagnostic expertise with potential applications in therapy suggestions, personalized surveillance, and prognostic evaluations. However, further validation and seamless integration into clinical practice are essential for realizing their full potential. Conclusion: This systematic study underscores the progress made in the application of AI and ML in HCC screening, diagnosis, and treatment. Numerous studies highlight the capability of AI and ML systems to enhance hepatocellular carcinoma diagnosis, predict outcomes, and optimize therapy. The enduring and versatile nature of these technologies points towards a revolutionary future in personalized and efficient HCC management.

2025· The Journal of Infectious Diseases8doi:10.1093/infdis/jiaf155

BACKGROUND: Decreased efficacy of artemether-lumefantrine, the globally most used antimalarial, has recently emerged in Africa. METHODS: An efficacy trial was carried out based on directly observed artemether-lumefantrine therapy at Bengo, Northern Angola. One-hundred Plasmodium falciparum uncomplicated malaria patients (2-10 years old) were enrolled, hospitalized for the treatment period, and followed up for 42 days. Polymerase chain reaction (PCR) correction was performed with pfmsp1/2 plus glurp, with analysis considering 2 or 3 coincident markers. Infections were tested by quantitative PCR (qPCR) for pfmdr1 copy number (pfmdr1×N), a potential P. falciparum marker of lumefantrine resistance previously identified in the region. In vitro clone mixtures were built and used to determine the relation between qPCR copy number scores and actual intrainfection quantitative fractions of pfmdr1×N. RESULTS: We observed a significant posttreatment selection of gene amplification, suggesting a role in the parasite in vivo response to this drug. pfmdr1×2 qPCR scores of 1.3, 1.4, and 1.5 were determined to correspond to 15%, 25%, and 35% intrainfection rates. Patients carrying infections with a score ≥1.4 at baseline were linked to decreased artemether-lumefantrine day 42 efficacy (79% vs 97% single-copy pfmdr1). All infections were pfmdr1 N86 carriers and no pfk13 mutations were found. CONCLUSIONS: Our study suggests pfmdr1×N as a marker of P. falciparum in vivo response to lumefantrine in Africa, while indicating patients carrying infections with a pretreatment pfmdr1×N score ≥1.4 before treatment are a group experiencing decreased artemether-lumefantrine performance.

2021· Journal of Religion & Spirituality in Social Work Social Thought8doi:10.1080/15426432.2021.1994099

This study explored whether license-holding mental health professionals exhibit comfort/discomfort in addressing religion and spirituality (RS) in practice. Through snowball sampling, 52 clinicians across different fields were recruited across Southern California. The participants were measured descriptively based on (a) comfort in their ability to integrate clients’ RS in treatment and (b) their comfort discussing clients’ RS strengths and struggles in treatment. Results revealed that, among practitioners, there was a 15–25% level of discomfort toward integrating and discussing RS in treatment. That is, between 75% and 85% of participants reported comfort in dealing with RS in practice. Licensed clinical social workers reported slightly lower discomfort level than other licensed professionals. However, Mann-Whitney U Test results revealed that field of practice (social workers versus non social workers) does not significantly correlate with comfort addressing and discussing RS in treatment. Implications of the findings were discussed.

While high-dose therapy and autologous stem cell transplant (ASCT) remain integral to the primary treatment of newly diagnosed transplant-elble multiple myeloma (MM) patients, the challenge of disease progression persists. The primary objective of this meta-analysis is to evaluate the efficacy and safety of tandem ASCT compared to single ASCT. We conducted a systematic review and meta-analysis of randomized controlled trials and observational studies comparing tandem ASCT with single ASCT in patients with newly diagnosed MM. We searched PubMed, EMBASE, Cochrane Library, and Clinical Trials databases for studies published up to January 2024. The primary outcomes were progression-free survival (PFS), overall survival (OS), overall response rate (ORR), complete response rate (CRR), and treatment-related mortality (TRM). We used a random-effects model to calculate pooled hazard ratios (HRs) and relative risks (RRs) with 95% confidence intervals (CIs). Study quality was assessed using the Cochrane risk of bias tool and Newcastle-Ottawa Scale. Twelve studies involving 5057 patients met the inclusion criteria. Tandem ASCT was associated with a significantly higher CRR compared to single ASCT (HR 1.33, 95% CI 1.03-1.71, I2 = 15%), but no significant differences were observed in PFS (HR 0.75, 95% CI 0.42-1.34, I2 = 14%), OS (HR 0.60, 95% CI 0.33-1.10, I2 = 27%), or the ORR (RR 0.80, 95% CI 0.59-1.08, I2 = 33%). However, tandem ASCT was associated with a significantly higher risk of TRM (RR 1.78, 95% CI 1.00-3.18, I2 = 0%). Tandem ASCT improves the CRR but does not provide significant benefits in terms of PFS, OS, or ORR compared to single ASCT in patients with newly diagnosed MM. Moreover, tandem ASCT is associated with a higher risk of TRM. The decision to pursue tandem ASCT should be made on an individual basis, carefully weighing the potential benefits and risks in light of each patient's unique clinical situation. Future research should focus on identifying patient subgroups most likely to benefit from tandem ASCT and exploring strategies to optimize the efficacy and safety of this approach in the context of novel agent-based therapies.

SUMMARY Reduced prevalence of diarrhea and mortality has been reported after dietary supplementation with zinc compounds in swine with naturally acquired colibacillosis and those challenge-exposed with Serpulina hyodysenteriae ; however, the usefulness of this approach for control of enteric diseases of swine remains to be determined. To examine the effect of dietary zinc-containing compounds on the colonization and development of cecal lesions associated with S hyodysenteriae infection, a defined diet alone or with added ZnO, ZnSO 4 , or Zn-methionine complex to a final concentration of approximately 6,000 mg of Zn 2+ /kg of complete feed was fed ad libitum to 156 female mice (strain C3H/HeN) for 10 days prior to oral inoculation either with S hyodysenteriae or sterile trypticase soy broth. Rations were continued for 42 days, while at weekly intervals, 3 mice/group were necropsied for determination of body weight, cecal weight, liver zinc concentration, presence of S hyodysenteriae in the cecum, and gross and histologic assessments of cecal lesions. From postinoculation day 0 to 42, the liver zinc concentration of mice fed the zinc-supplemented diets was approximately twice that of mice fed the basal diet, irrespective of the source of zinc. From postinoculation day 7 through 42, the overall recovery rate of S hyodysenteriae in infected mice fed the basal diet was 77.8%. In contrast, recovery rates of S hyodysenteriae from S hyodysenteriae -inoculated mice fed the zinc-supplemented diets were 0% for Zn-methionine and ZnO and 16.7% for ZnSO 4 . Mice fed the basal diet had significantly ( P &lt; 0.05) higher weight gain than mice fed the zinc-supplemented diets. However, the severity of cecal lesions, as determined by histologic examination and quantitative determination of longitudinal crypt length of the cecum was significantly ( P &lt; 0.05) less in mice fed the zinc-supplemented diets than in mice fed the basal diet. Data from this study indicate that dietary supplementation with 6,000 mg of zinc/kg of feed significantly reduced the recovery rate of S hyodysenteriae and provided partial protection against development of cecal lesions in mice inoculated with S hyodysenteriae . However, at this concentration, zinc had a deleterious effect on growth of the mice.

Background Chimeric antigen receptor T-cell (CAR-T) therapy has emerged as a promising immunotherapy for various malignancies. However, its use is associated with challenges, including cytokine release syndrome (CRS), a potentially severe complication. This retrospective study aims to analyze the risks, outcomes, and healthcare burden of CRS in patients undergoing CAR-T therapy. Method Data from the 2020 National Inpatient Sample (NIS) were utilized, comprising 415 CAR-T-related hospitalizations. They were categorized into those with CRS (n = 68) and those without CRS (n = 347). Baseline characteristics, including age, gender, race, income, insurance status, and comorbidities, were compared. Outcomes of interest included in-hospital mortality, length of stay (LOS), total hospital charges, and access to complications, associations, and interventions. Statistical analyses, including multivariable models, were employed to assess associations. Results Hospitalizations with CRS did not exhibit significant differences in age, gender, race, income, or insurance status compared to those without CRS. The multivariable analysis showed no statistically significant difference in mortality (adjusted odds ratio (aOR) = 2.48, 95% confidence interval (CI): 0.71 to 8.69, p = 0.151), LOS (coefficient = -2.1 days, 95% CI: -5.43 to 1.21, p = 0.207), or total hospital charges (coefficient = $207,456, 95% CI: $6119 to $421,031, p = 0.057) between the two groups. The CRS group had a higher incidence of fever (aOR = 1.91, 95% CI: 1.15 to 3.17, p = 0.014), acute respiratory failure (aOR = 2.10, 95% CI: 1.01 to 4.40, p= 0.049), and the need for intubation/mechanical ventilation (aOR = 2.59, 95% CI: 1.14 to 5.88, p = 0.024). Hemophagocytic lymphohistiocytosis (HLH) was significantly associated with CRS (aOR = 6.72, 95% CI: 2.03 to 22.18, p = 0.002). Conclusion While the development of CRS in CAR-T-treated patients did not significantly increase mortality, LOS, or total hospital charges, it was associated with specific risks and outcomes, including fever, respiratory failure, and HLH. This study emphasizes the importance of vigilance in recognizing and managing CRS in CAR-T therapy to optimize patient outcomes. The findings contribute valuable insights to guide clinical decision-making in the context of CAR-T therapy.

Objective: The objective of this study is to thoroughly investigate the use of artificial intelligence (AI) and machine learning (ML) techniques for diagnosing and predicting prognosis in gastric cancer, utilizing the latest available data. Methods: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA)guidelines, a systematic review investigated AI and ML applications in gastric cancer diagnosis and prognostic prediction. PubMed and Google Scholar were searched from February 2019 to January 2024 using specific syntax. Eligible trials were selected based on inclusion criteria including recent publication, focus on AI and ML in gastric cancer, and reporting diagnostic or prognostic outcomes. Data were extracted and quality assessed independently, with discrepancies resolved through discussion. Due to design heterogeneity, detailed analysis was omitted, and descriptive summaries of included articles were provided. Results: This review included a total of 8 articles. AI and ML techniques, including convolutional neural networks (CNN) and deep learning models, have played pivotal roles in accurately diagnosing chronic atrophic gastritis, predicting postoperative gastric cancer prognosis, and identifying peritoneal metastasis in gastric cancer patients. These technologies offer potential advantages such as streamlining diagnostic procedures, guiding treatment decisions, and enhancing patient outcomes in gastric cancer management. Conclusion: In the near future, AI applications may have a significant role in the diagnosis and prognosis prediction of gastric cancer.

Munchausen Syndrome

1994· Plastic Surgical Nursing5doi:10.1097/00006527-199401440-00006

Munchausen Syndrome is an unusual subset of symptoms experienced by patients who self-inflict artificial illness. Caring for Munchausen patients, who are frequently finding their way into plastic surgery practices, is very time consuming because they often fail to respond to standard modalities of treatment. They abuse the medical system by seeking care from one or more caregivers at the same time and appear to relish repeating expensive diagnostic procedures. Four case studies are presented in this article along with suggestions for treating these patients.

Background: Cervical cancer poses a substantial global health challenge, predominantly affecting underprivileged countries. The limitations of current screening methods, such as cytology and visual examination, underscore the need for improved techniques. Artificial intelligence (AI) and machine learning (ML), particularly convolutional neural networks, offer promising solutions in this regard. Methodology: Fifteen studies meeting the inclusion criteria were examined. The PRISMA criteria guided the exploration of cervical cancer screening studies employing AI, ML, and deep learning on PubMed/MEDLINE and Google Scholar. The search focused on "artificial intelligence" and "Pap smear." The investigation specifically delves into English-language studies post-2019 that pertain to the machine learning and deep learning classification of cervical cancer using mobile devices. Histology, animal research, and pre-2019 investigations are excluded. Titles and abstracts were carefully reviewed for any discrepancies and subsequently discussed. The process of data extraction involved compiling information from the selected articles. Result: The systematic review investigates the impact of AI and ML on cervical cancer detection, screening, and diagnosis. Our review reveals enhanced accuracy and efficiency in innovative technologies such as CytoBrain and computer-aided diagnostic systems employing Compact VGG and ResNet101. ML techniques like logistic regression, MLP, SVM, KNN, and naive Bayes prove beneficial for managing complex datasets, particularly when combined with class-balancing procedures. The promising aspects include the application of deep learning for automation and AI-assisted digital microscopy. These findings signify a transformative shift in cervical cancer screening, underscoring the potential of ML and AI technologies to elevate diagnostic accuracy and accessibility. Conclusion: Our study demonstrates advancements in both accuracy and responsiveness. Despite recognizing scientific and ethical considerations, the study underscores the potential of AI to enhance cervical cancer care. This systematic review advocates for policymakers and healthcare practitioners to use ongoing research for informed decision-making in this rapidly evolving field.
