Review
Bovine mastitis remains a major prevalent disease in cattle and places a significant economic burden on the global dairy industry. The goal of this systematic review and meta-analysis was to examine the overall prevalence of mastitis and its associated risk factors among dairy cows. Scientific articles written in English were recovered from PubMed, ScienceDirect, Web of Science, Google Scholar, Cochrane Library, and other sources from Google Engine and University Library Databases. "Prevalence," "bovine mastitis," "clinical mastitis," "subclinical mastitis," "associated factors," "dairy cows," and "Ethiopia" were search terms used for this study. For critical appraisal, PRISMA 2009 was applied. Heterogeneity and publication bias were evaluated using Cochran's , inverse variance ( ), and funnel plot asymmetry tests. A random-effects model was used to calculate the pooled burden of mastitis and its associated factors among dairy cows, along with the parallel odds ratio (OR) and 95% confidence interval (CI). A total of 6438 dairy cows were included in the 17 eligible studies for this meta-analysis. The overall pooled prevalence of mastitis among dairy cows in Ethiopia was 43.60% (95% CI: 34.71, 52.49), of which 12.59% (95% CI: 7.18, 18.00) and 32.21% (95% CI: 24.68, 39.74) were clinical and subclinical cases, respectively. Of the regions, the highest and lowest pooled prevalence estimates of mastitis among dairy cows were 49.90% (95% CI: 31.77, 68.03) and 25.09% (95% CI: 3.86, 46.32) in the Oromia and Amhara regions, respectively. The highest pooled prevalence estimate in the study period was recorded between 2017 and 2022, with a pooled prevalence estimate of 46.83% (95% CI: 35.68, 57.97), followed by the study period from 2005 to 2016, with a pooled prevalence estimate of 39.97% (95% CI: 25.50, 54.44). Gram-positive bacteria (84.70%) were the most prevalent mastitis-causing agents compared with Gram-negative bacteria (15.30%). Breed (AOR: 2.17, 95% CI: 1.44, 2.90), lactation stage (AOR: 1.59, 95% CI: 1.04, 2.15), parity (AOR: 3.31, 95% CI: 1.69, 4.94), history of mastitis (AOR: 3.56, 95% CI: 2.40, 4.71), floor type (AOR: 1.59, 95% CI: -0.16, 3.34), and teat injury (AOR: 6.98, 95% CI: 0.33, 13.64) were factors significantly associated with mastitis among dairy cows in Ethiopia. Early diagnosis and proper medication, as well as implementing appropriate prevention and control measures, are necessary for the management of mastitis in dairy cows.

Meta-Analysis Review
BACKGROUND
Up to now, there is controversy over the effect of delivery mode cesarean delivery and spontaneous vaginal delivery on sexual function. Therefore, we did a systematic review and meta-analysis in postpartum women to explore the mode of delivery, cesarean delivery, and spontaneous vaginal delivery and differences in postpartum sexual function (short- and long-term) in Chinese primiparous women.
METHODS
Comprehensive electronic searches of PubMed, EMBASE, Web of Science, Elsevier Science Direct, Cochrane Library, the Chinese Biological Medical Literature database and the Chinese National Knowledge Infrastructure database were conducted to identify any study in each database published to August 31, 2017. The primary outcome was the sexual satisfaction and the secondary outcomes were resumed intercourse and sexual pain in the postpartum.
RESULTS
We identified 10 studies with a total population of 2851 in the present meta-analysis. Five and six eligible articles were respectively included for sexual satisfaction in postpartum at 3- and 6 months. Compared with vaginal delivery group, two time points were all not found statistically significance (OR 1.53, 95%CI 0.93-2.49; OR 1.15, 95%CI 0.95-1.39, respectively) in cesarean and spontaneous vaginal delivery group; in resumed intercourse and sexual pain domains, they were all significantly, with an overall OR of 2.05 (95%CI 1.36-3.11) at 3 months, 1.50 (95%CI 1.04-2.16) at 6 months and 0.29 (95%CI 0.24, 0.36) at 3 months, 0.73 (95%CI 0.58, 0.93) at 6 months, respectively. With the passage of time, the gap was closing. Sensitivity analysis was indicated a good stability of the meta-analysis in each domain.
CONCLUSIONS
In conclusion, this meta-analysis indicated that the mode of delivery, cesarean and spontaneous vaginal delivery did not affect postpartum sexual satisfaction (short- and long-term) and appeared to have minimal effect on the long-term resumed intercourse and sexual pain in Chinese primiparous women. Primiparous women should be more cautious to choose cesarean section in order to preserve sexual function.

Meta-Analysis Review
BACKGROUND
Although rates have declined, hysterectomy is still a frequent gynaecological procedure. To date, there has been no systematic quantification of the relationships between early/mid-life exposures and hysterectomy. We performed a systematic review and meta-analyses to quantify the associations between age at menarche, education level, parity and hysterectomy.
METHODS
Eligible studies were identified by searches in PubMed and Embase through March 2015. Study-specific estimates were summarised using random effects meta-analysis. Heterogeneity was explored using sub-group analysis and meta-regression.
RESULTS
Thirty-two study populations were identified for inclusion in at least one meta-analysis. Each year older at menarche was associated with lower risk of hysterectomy-summary hazard ratio 0.86 (95% confidence interval: 0.78, 0.95; I2 = 0%); summary odds ratio 0.88 (95% confidence interval: 0.82, 0.94; I2 = 61%). Low education levels conferred a higher risk of hysterectomy in the lowest versus highest level meta-analysis (summary hazard ratio 1.87 (95% confidence interval: 1.25, 2.80; I2 = 86%), summary odds ratio 1.51 (95% confidence interval: 1.35, 1.69; I2 = 90%)) and dose-response meta-analysis (summary odds ratio 1.17 (95% confidence interval: 1.12, 1.23; I2 = 85%) per each level lower of education). Sub-group analysis showed that the birth cohort category of study participants, the reference category used for level of education, the year the included article was published, quality of the study (as assessed by the authors) and control for the key variables accounted for the high heterogeneity between studies in the education level meta-analyses. In the meta-analyses of studies of parity and hysterectomy the results were not statistically significant.
CONCLUSIONS
The present meta-analyses suggest that the early life factors of age at menarche and lower education level are associated with hysterectomy, although this evidence should be interpreted with some caution due to variance across the included studies.

Review
BACKGROUND
Inflammatory bowel disease (IBD) is a chronic disease placing a large health and economic burden on health systems worldwide. The treatment landscape is complex with multiple strategies to induce and maintain remission while avoiding long-term complications. The extent to which rising treatment costs, due to expensive biologic agents, are offset by improved outcomes and fewer hospitalisations and surgeries needs to be evaluated. This systematic review aimed to assess the cost-effectiveness of treatment strategies for IBD.
MATERIALS AND METHODS
A systematic literature search was performed in March 2017 to identify economic evaluations of pharmacological and surgical interventions, for adults diagnosed with Crohn's disease (CD) or ulcerative colitis (UC). Costs and incremental cost-effectiveness ratios (ICERs) were adjusted to reflect 2015 purchasing power parity (PPP). Risk of bias assessments and a narrative synthesis of individual study findings are presented.
RESULTS
Forty-nine articles were included; 24 on CD and 25 on UC. Infliximab and adalimumab induction and maintenance treatments were cost-effective compared to standard care in patients with moderate or severe CD; however, in patients with conventional-drug refractory CD, fistulising CD and for maintenance of surgically-induced remission ICERs were above acceptable cost-effectiveness thresholds. In mild UC, induction of remission using high dose mesalazine was dominant compared to standard dose. In UC refractory to conventional treatments, infliximab and adalimumab induction and maintenance treatment were not cost-effective compared to standard care; however, ICERs for treatment with vedolizumab and surgery were favourable.
CONCLUSIONS
We found that, in general, while biologic agents helped improve outcomes, they incurred high costs and therefore were not cost-effective, particularly for use as maintenance therapy. The cost-effectiveness of biologic agents may improve as market prices fall and with the introduction of biosimilars. Future research should identify optimal treatment strategies reflecting routine clinical practice, incorporate indirect costs and evaluate lifetime costs and benefits.

Review
Lactoferrin (LF) is a breast milk glycoprotein with antimicrobial and anti-inflammatory effects. Its beneficial properties in infants, especially in those born preterm, are currently being studied in clinical trials. However, the maternal and nursing infant factors that may affect LF concentration in breast milk are still not clear. We conducted a systematic review to investigate the factors that may affect the concentration of LF in breast milk. We used a 2-step approach to identify the eligible studies according to inclusion/exclusion criteria, and to determine which studies would be considered. We included 70 qualified articles from 29 countries with publication dates ranging from 1976 to 2015. We described the correlation between LF concentration in breast milk and lactation stage; 10 maternal factors, such as race, parity, among others; and 2 infant factors: infections and prematurity. Colostrum has the highest LF levels, but they decrease with days postpartum. No other factor has been consistently associated with LF concentration. A major limitation of the majority of the published studies is the small sample size and the different methods used to measure LF concentration. Therefore, there is a need for large, multicenter studies with standardized study design, sample collection, and LF measurement methods to identify clinically significant factors associated with LF expression in breast milk, which will help promote exclusive breastfeeding in preterm infants.

Review
Stroke, a leading cause of death and long-term disability, has a considerable social and economic impact. It is imperative to investigate stroke-related costs. The main goal was to conduct a systematic literature review on the described costs associated with stroke care continuum to better understand the evolution of the economic burden and logistic challenges. This research used a systematic review method. We performed a search in PubMed/MEDLINE, ClinicalTrial.gov, Cochrane Reviews, and Google Scholar confined to publications from January 2012 to December 2021. Prices were adjusted using consumer price indices of the countries in the studies in the years the costs were incurred to 2021 Euros using the World Bank and purchasing power parity exchange rate in 2020 from the Organization for Economic Co-operation and Development with the XE Currency Data API. The inclusion criteria were all types of publications, including prospective cost studies, retrospective cost studies, database analyses, mathematical models, surveys, and cost-of-illness (COI) studies. Were excluded studies that (a) were not about stroke, (b) were editorials and commentaries, (c) were irrelevant after screening the title and abstract,(d) grey literature and non-academic studies, (e) reported cost indicators outside the scope of the review, (f) economic evaluations (i.e., cost-effectiveness or cost-benefit analyses); and (g) studies not meeting the population inclusion criteria. There may be risk of bias because the effects are dependent on the persons delivering the intervention. The results were synthetized by PRISMA method. A total of 724 potential abstracts were identified of which 25 articles were pulled for further investigation. The articles were classified into the following categories: 1)stroke primary prevention, 2) expenditures related to acute stroke care, 3) expenditures for post-acute strokes, and 4) global average stroke cost. The measured expenditures varied considerably among these studies with a global average cost from €610-€220,822.45. Given the great variability in the costs in different studies, we can conclude that we need to define a common system for assessing the costs of strokes. Possible limitations are related to clinical choices exposed to decision rules that trigger decisions alerts within stroke events in a clinical setting. This flowchart is based on the guidelines for acute ischemic stroke treatment but may not be applicable to all institutions.

OBJECTIVES
To systematically review studies eliciting monetary value of a statistical life (VSL) estimates within, and across, different sectors and other contexts; compare the reported estimates; and critically review the elicitation methods used.
METHODS
In June 2019, we searched the following databases to identify methodological and empirical studies: Cochrane Library, Compendex, Embase, Environment Complete, Informit, ProQuest, PubMed, Scopus, and Web of Science. We used the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines for reporting and a modified Consolidated Health Economic Evaluation Reporting Standards checklist to assess the quality of included studies.
RESULTS
We identified 1455 studies, of which we included 120 in the systematic review. A stated-preference approach was used in 76 articles, with 51%, 41%, and 8% being contingent valuation studies, discrete-choice experiments, or both, respectively. A revealed-preference approach was used in 43 articles, of which 74% were based on compensating-wage differentials. The human capital approach was used in only 1 article. We assessed most publications (87%) as being of high quality. Estimates for VSL varied substantially by context (sector, developed/developing country, socio-economic status, etc), with the median of midpoint purchasing power parity-adjusted estimates of 2019 US$5.7 million ($6.8 million, $8.7 million, and $5.3 million for health, labor market, and transportation safety sectors, respectively).
CONCLUSIONS
The large variation observed in published VSLs depends mainly on the context rather than the method used. We found higher median values for labor markets and developed countries. It is important that health economists and policymakers use context-specific VSL estimates. Methodological innovation and standardization are needed to maximize comparability of VSL estimates within, and across, sectors and methods.

Review
BACKGROUND
Posttraumatic stress disorder is associated with a high economic burden. Costs of treatment are known to be high, and cost-effectiveness has been analysed for several treatment options.
OBJECTIVE
As no review on economic aspects of posttraumatic stress disorder exists, the aim of this study was to systematically review costs-of-illness studies and economic evaluations of therapeutic treatment for posttraumatic stress disorder, and to assess their quality.
METHOD
A systematic literature search was performed in March 2017 and was last updated in February 2020 in the databases PubMed, PsychInfo and NHS Economic Evaluation Database. Cost-of-illness studies and economic evaluations of treatment for posttraumatic stress disorder were selected. Extracted cost data were categorized as direct costs and indirect costs and inflated to 2015 US-$ purchasing power parities (PPP). Quality was assessed using an adapted cost-of-illness studies quality checklist, the Consensus on Health Economic Criteria list, and the questionnaire to assess relevance and credibility of modelling studies by the International Society for Pharmacoeconomics and Outcome Research.
RESULTS
In total, 13 cost-of-illness studies and 18 economic evaluations were included in the review. Annual direct excess costs ranged from 512 US-$ PPP to 19,435 US-$ PPP and annual indirect excess costs were 5,021 US-$ PPP per person. Trauma-focused cognitive-behavioural therapy (+selective serotonin re-uptake inhibitor) was found to be cost-effective compared with treatment as usual and no treatment. Overall, included studies were of low and moderate quality. Studies used inappropriate economic study designs and lacked information on the economic perspective used.
CONCLUSIONS
Posttraumatic stress disorder is a major public health problem that causes high healthcare costs. While trauma-focused cognitive-behavioural therapy was found to be cost-effective, further investigations regarding pharmacotherapy and other treatments are necessary.

Review
OBJECTIVE
To identify and assess the current evidence available about the costs of managing hospitalized pediatric patients diagnosed with Respiratory Syncytial Virus (RSV) and Parainfluenza Virus Type 3 (PIV3) in upper-middle-income countries.
METHODS
The authors conducted a systematic review across seven key databases from database inception to July 2022. Costs extracted were converted into 2022 International Dollars using the Purchasing Power Parity-adjusted. PROSPERO identifier: CRD42020225757.
RESULTS
No eligible study for PIV3 was recovered. For RSV, cost analysis and COI studies were performed for populations in Colombia, China, Malaysia, and Mexico. Comparing the total economic impact, the lowest cost per patient at the pediatric ward was observed in Malaysia ($ 347.60), while the highest was in Colombia ($ 709.66). On the other hand, at pediatric ICU, the lowest cost was observed in China ($ 1068.26), while the highest was in Mexico ($ 3815.56). Although there is no consensus on the major cost driver, all included studies described that the medications (treatment) consumed over 30% of the total cost. A high rate of inappropriate prescription drugs was observed.
CONCLUSION
The present study highlighted how RSV infection represents a substantial economic burden to health care systems and to society. The findings of the included studies suggest a possible association between baseline risk status and expenditures. Moreover, it was observed that an important amount of the cost is destinated to treatments that have no evidence or support in most clinical practice guidelines.

Review
PURPOSE OF REVIEW
Racial and socioeconomic inequities in respiratory pandemics have been consistently documented, but little official guidance exists on effective action to prevent these. We systematically reviewed quantitative evaluations of (real or simulated) interventions targeting racial and socioeconomic inequities in respiratory pandemic outcomes.
RECENT FINDINGS
Our systematic search returned 10,208 records, of which 5 met inclusion criteria, including observational ( = 1), randomized trial ( = 1), and simulation ( = 3) studies. Interventions studied included vaccination parity, antiviral distribution, school closure, disinfection, personal protective equipment, and paid sick leave, with a focus on Black ( = 3) and/or Latinx ( = 4) or low-SES ( = 2) communities. Results are suggestive that these interventions might be effective at reducing racial and/or SES disparities in pandemics.
SUMMARY
There is a dearth of research on strategies to reduce pandemic disparities. We provide theory-driven, concrete suggestions for incorporating equity into intervention research for pandemic preparedness, including a focus on social and economic policies.
