Development and clinical application of an evidence-based pharmaceutical care service algorithm in acute coronary syndrome.

WHAT IS KNOWN AND OBJECTIVE: Drug therapies are critical for preventing secondary complications in acute coronary syndrome (ACS). The purpose of this study was to develop and apply a pharmaceutical care service (PCS) algorithm for ACS and confirm that it is applicable through a prospective clinical trial. METHODS: The ACS-PCS algorithm was developed according to extant evidence-based treatment and pharmaceutical care guidelines. Quality assurance was conducted through two methods: literature comparison and expert panel evaluation. The literature comparison was used to compare the content of the algorithm with the referenced guidelines. Expert evaluations were conducted by nine experts for 75 questionnaire items. A trial was conducted to confirm its effectiveness. Seventy-nine patients were assigned to either the pharmacist-included multidisciplinary team care (MTC) group or the usual care (UC) group. The endpoints of the trial were the prescription rate of two important drugs, readmission, emergency room (ER) visit and mortality. RESULTS AND DISCUSSION: The main frame of the algorithm was structured with three tasks: medication reconciliation, medication optimization and transition of care. The contents and context of the algorithm were compliant with class I recommendations and the main service items from the evidence-based guidelines. Opinions from the expert panel were mostly positive. There were significant differences in beta-blocker prescription rates in the overall period (P = .013) and ER visits (four cases, 9.76%, P = .016) in the MTC group compared to the UC group, respectively. WHAT IS NEW AND CONCLUSION: We developed a PCS algorithm for ACS based on the contents of evidence-based drug therapy and the core concept of pharmacist services.

[The coping styles and its relationship with quality of life among 1 968 female breast cancer patients in Shanghai in 2014].

Objective: To study the coping styles and its relationship with quality of life among part of the female breast cancer patients in Shanghai in 2014. Methods: In August of 2014, 1-3 block groups affiliated to Shanghai Cancer Rehabilitation Club were selected from each of the 17 districts of Shanghai by convenient sampling method. Respondents were recruited from these block groups via putting up posters in the community or top three hospitals nearby. The inclusion criteria were as follows: female, aged from 18 to 80 years old; the initial diagnosis or primary tumor was breast cancer, and active treatments including surgery, radiotherapy and chemotherapy were finished; capable of basic reading and comprehension, and there was no communication disorder; daily activities were not limited, and with no mental disorder or dysgnosia. Totally 2 205 respondents were included. Questionnaire survey was conducted to collect the information of demographic characteristics, disease characteristics, result of European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30), and result of the Ways of Coping Inventory-Cancer Version (WOC-CA). 1 968 valid questionnaires were withdrawn. The results of respondent characteristics and WOC-CA were under descriptive analysis, and the differences of coping styles among groups of different demographic characteristics were compared using t test. In addition, we analyzed the correlation between respondents' coping styles and quality of life using partial correlation analysis. Results: The average age of the 1 968 respondents was (58.7±7.4) years old, and BMI was (24.4±5.4) kg/m(2). The score of positive coping styles was 2.04±0.41, and the score of negative coping styles was 1.79±0.33. The scores of Physical Functioning (PF), Role Functioning (RF), Cognitive Functioning (CF), Emotional Functioning (EF), Social Functioning (SF), and Global Health (GH) were 83.40±12.18, 90.80±15.92, 80.72±16.29, 84.67±15.19, 80.99±20.91, 65.27±21.21, respectively. Positive coping styles correlated with PF, EF, and GH positively, and the correlation coefficients were separately 0.581 (P=0.046), 0.593 (P=0.045), 0.770 (P<0.001). Negative coping styles correlated with RF, CF, EF, and SF negatively, and the correlation coefficients were separately-0.672 (P=0.021),-0.815 (P=0.005),-0.121 (P<0.001),-0.123 (P<0.001). Conclusion: Part of the female breast cancer patients in Shanghai in 2014 mainly adopted positive coping styles, and in general the positive coping styles correlated with quality of life positively and negative coping styles correlated with quality of life negatively.

[Effects and its mechanism of Nimotuzumab on radiosensitivity of esophageal carcinoma ECA-109 and TE-13 cell lines].

Objective: To investigate the effects of nimotuzumab on radiosensitivity of ECA-109 and TE-13 esophageal carcinoma cell lines and explore its possible mechanism. Methods: The ECA-109 and TE-13 cells were divided into control group, irradiation group, medicine group, and combined group (irradiation + medicine). In the combined group, ECA-109 and TE-13 cells were treated with nimotuzumab for 24 h before irradiation, and the cells were collected 2 h after irradiation. The radiosensitizing effects of nimotuzumab on ECA-109 and TE-13 cells were evaluated by clone formation assay. Cell apoptosis was detected by flow cytometry. Western blotting was used to evaluate the expression of EGFR, p-EGFR, DNA-PKcs, p-DNA-PKcs and γH2AX. Results: The values of Dq (quasithreshold dose), D0(mean lethal dose)and SF2 (surviving fraction at 2 Gy) of ECA-109 and TE-13 cells in the combined group were significantly lower than those of the radiation group (for ECA-109 cells, 1.11 vs. 1.72, 1.40 vs. 2.14, 0.42 vs. 0.66, respectively; for TE-13 cells, 0.41 vs. 0.46, 0.43 vs. 0.65, 0.40 vs. 0.71, respectively (all P<0.05). The sensitivity enhancement ratio (SER) of ECA-109 and TE-13 cells were 1.35 and 1.43, respectively. Flow cytometry showed that the apoptosis rate of ECA-109 and TE-13 cells in the combined group were significantly higher than those of the radiation group [for ECA-109 cells, (41.31±1.52)% vs. (9.54±0.52)%; for TE-13 cells, (46.28±0.28)% vs. (11.32±0.31)%, both P<0.01]. Western blotting showed that the expression levels of EGFR and DNA-PKcs were not significantly different in all groups (all P>0.05). Compared with those of the control group, p-EGFR and p-DNA-PKcs of the radiation group were significantly higher in both cell lines (P<0.05), and the γH2AX levels in the radiation group and medicine group were significantly higher than that of the control group (P<0.05). Compared with those of the radiation group and medicine group, p-EGFR and p-DNA-PKcs protein expression in the combined group were decreased significantly (P<0.05), while γH2AX protein expression was significantly increased (P<0.05). Conclusions: Nimotuzumab can enhance the radiosensitivity of esophageal cancer ECA-109 and TE-13 cells. The potential mechanism may be related to the inhibition of EGFR phosphorylation and down-regulation of DNA damage repair proteins. The radiosensitizing effect of nimotuzumab is greater on poorly differentiated esophageal cancer cells.

Association between p53 codon 72 polymorphisms and clinical outcome of nasopharyngeal carcinoma.

We conducted a cohort study to investigate whether polymorphisms in p53 at codon 72 are associated with tumor response and survival time of advanced nasopharyngeal carcinoma (NPC) patients treated with radiotherapy. The study population included 127 subjects with NPC who were enrolled at Binzhou Medical University between September 2008 and December 2009. Cox proportional hazard regression was used to assess the association between polymorphisms in the p53 gene and progression-free survival (PFS) and overall survival (OS) of NPC patients. During the follow-up period, 42 patients died and 72 patients showed progression at the end of the study. Of the 127 patients, median PFS was 22.5 ± 1.2 months (1-36 months), and the median OS time was 28.2 ± 1.1 months (2-36 months). The p53 codon 72 Pro/Pro genotype was associated with a longer median PFS time of 30.3 months compared with 18.2 months for patients with Arg/Arg variants. Moreover, the p53 codon 72 Pro/ Pro genotype was associated with a longer median OS time of 31.6 months compared with 25.8 months for those with Arg/Arg variants; the P value was marginally significant. We showed that variants in p53 codon 72 may be an independent predictor for PFS and OS of NPC patients.

Occurrence of Fusarium commune and F. oxysporum in Horseradish Roots.

This study was conducted to investigate the etiology of internal discoloration of horseradish roots. Several species of Fusarium and Verticillium were isolated from internally discolored horseradish roots collected from commercial fields in Illinois and research plots in Wisconsin during 2008 and 2009. Eleven isolates of Fusarium, identified as Fusarium oxysporum based on morphological features, were characterized by DNA sequencing of the nuclear translation elongation factor 1α (EF-1α) and mitochondrial small-subunit ribosomal DNA (mtSSU rDNA). Maximum parsimony analyses of DNA sequences from these two regions and the combined data set revealed that six isolates were clearly separated into a common clade that contained F. commune, with the remaining five isolates being grouped into a common clade with F. oxysporum. Based on the DNA sequence data, we considered the six isolates grouped into a common clade with F. commune to be F. commune. Pathogenicity tests of F. commune and F. oxysporum were conducted on two horseradish cultivars, '1573' and 'Big Top Western', in a greenhouse. Root segments were inoculated by dipping them in a conidial suspension and then growing them in pots in a greenhouse for 4 months. For plants inoculated with F. commune, internal root discoloration and root rot developed 1 month after inoculation and almost all roots of the plant were completely rotten 4 months after inoculation. Inoculation of the plants with F. oxysporum resulted in only internal root discoloration but not root rot symptoms. This is the first report of F. commune causing internal discoloration and root rot of horseradish.

Combined carbamazepine and pregabalin therapy in a rat model of neuropathic pain.

BACKGROUND: Carbamazepine and pregabalin have proven effects against neuropathic pain. Carbamazepine blocks voltage-dependent Na(+) channels, whereas pregabalin blocks voltage-dependent Ca(2+) channels. The authors hypothesized that the co-administration of these drugs would synergistically reduce neuropathic pain. METHODS: Neuropathic pain was induced by L5 nerve ligation in Sprague-Dawley rats. To determine their ED(50) values, carbamazepine and pregabalin were orally administered at 0.3, 3, 10, or 30 mg kg(-1). The drugs were then co-administered at 0, 1/4×ED(50), 1/2×ED(50), 1.5×ED(50), and 2×ED(50) to determine the ED(50) and ED(75) values of the drugs in combination. Allodynia was determined using the von Frey hair test and dose-effect curves and isobolograms were used to investigate drug interactions. Levels of the acute reactive protein c-Fos in the dorsal horn were evaluated as an indicator of pathological nerve excitation. RESULTS: At ED(50) levels, carbamazepine and pregabalin did not exhibit synergism, but doses higher than ED(75) were found to be synergistic. The combination index was 0.18 (strong synergy) and dose reductions were 35.7-fold for carbamazepine and 6.8-fold for pregabalin when co-administered when compared with a single administration at ED(75). The percentage allodynia relief was only 60% for carbamazepine and 80% for pregabalin by single administration, whereas their co-administration relieved allodynia by 100%. Furthermore, treatment decreased c-Fos expression in the dorsal horn, but expressional differences between animals treated with carbamazepine plus pregabalin were not significantly different from those treated with single drug. CONCLUSIONS: Carbamazepine and pregabalin ameliorate neuropathic pain synergistically at higher doses.

Phase I study of concurrent selective lymph node late course accelerated hyper-fractionated radiotherapy and pemetrexed, cisplatin for locally advanced esophageal squamous cell carcinoma.

The optimized concurrent chemoradiotherapy has not been established for patients with advanced esophageal squamous cell carcinoma (SCC). The aim of the present study was to evaluate the safety and efficacy of concurrent chemotherapy and selective lymph node (SLN) late course accelerated hyperfractionated (LCAF) intensity modulated radiotherapy (IMRT) for the patients with thoracic SCC. Twelve patients with T3-4N0-1M0-1a thoracic esophageal SCC were included. The total dose of SLN LCAF IMRT was 59.6 Gy/34 fractions in 5.4 weeks. The concurrent chemotherapy protocol was as following: cisplatin 10 mg/m(2) on days 1-5 and 22-26, pemetrexed in escalating doses, from the base level of 500 mg/m(2) once every 21 days. The primary objectives were to determine the maximum tolerated dose (MTD), recommended dose (RD), and dose limiting toxicities (DLTs). Secondary end point included determination of preliminary radiographic response rates. As a result, three patients were enrolled in dose level 1 with pemetrexed 500 mg/m(2) and nine patients in dose level 0 with 400 mg/m(2) , respectively. At dose level 1, DLTs occurred in two of three patients. However, only two of nine patients in Level 0 developed DLTs. The complete response and partial response were observed in eight and four patients, respectively. Furthermore, no patient experienced cancer progression with a median follow-up of 9 months. In conclusion, the concurrent SLN LCAF IMRT and chemotherapy is feasible. The MTD of pemetrexed in this regimen was 500 mg/m(2) and RD was 400 mg/m(2) . Although toxicities were common, the protocol was safe, well tolerated, and achieved an encouraging outcome.

[Clinical characteristics of patients with multiple myeloma harboring 6q deletion].

Objective: To study the clinical and cytogenetic characteristics of patients with multiple myeloma harboring 6q deletion, with the aim to determine the impact of 6q deletion on survival. Methods: This study included the retrospective analysis of 382 newly diagnosed patients with multiple myeloma in our hospital from 2014 to 2017 and compared the clinical and cytogenetic characteristics between patients with and without 6q deletion. The log-rank test and the Cox proportional hazards regression model were used to analyze prognostic factors for progression-free survival (PFS) and overall survival (OS) . Results: Compared to those without 6q, the patients with 6q deletion were older (median age, 63 vs 58 years, P=0.039) , had higher incidence of t (4; 14) (30.4% vs 16.4% , P=0.020) , and higher proportion of complex karyotypes (22.2% vs 5.3% , P=0.001) . Univariate survival analysis using the log-rank test revealed that 6q deletion was associated with shorter PFS. However, by the Cox multivariate proportional hazards regression model, 6q deletion was not an independent prognostic factor and its effect on survival was affected by age, t (4; 14) , and other risk factors. Conclusions: 6q deletion was common in elderly patients with multiple myeloma and was often accompanied by t (4;14) and complex karyotypes. However, 6q deletion was not an independent prognostic factor for multiple myeloma.

Prognostic value of 18F-FDG PET/CT before and after radiotherapy for locally advanced nasopharyngeal carcinoma.

BACKGROUND: The purpose of this study was to evaluate the prognostic value of maximal standard uptake values (SUVs(max)) from serial fluor-18-fluorodeoxyglucose positron emission tomography/computed tomography ((18)F-FDG PET/CT) in patients with locally advanced nasopharyngeal carcinoma (NPC). MATERIALS AND METHODS: From October 2002 to January 2004, 62 patients with locally advanced NPC who underwent (18)F-FDG PET/CT scan before and after radiotherapy were reviewed retrospectively. We examined the association of SUV(max) and the results of long-term follow-up of the patients. RESULTS: Patients having tumors with a lower SUV(max) had significantly better 5-year overall survival (OS) (P= 0.0187) and disease-free survival (DFS) (P = 0.0163) than patients with a greater SUV(max). The patients who showed with metabolic complete response had a significantly higher 5-year OS (P = 0.0237) and DFS (P = 0.0186) than patients with metabolic partial response. Poor prognosis was found in patients with the SUV(max) of neck nodes larger than that at the primary tumor site (SUV(max-N) > SUV(max-P)) (P = 0.0440). CONCLUSIONS: (18)F-FDG uptake, as measured by the SUV(max) before radiotherapy and metabolic response after radiotherapy, may predict the prognosis in locally advanced NPC. High (18)F-FDG uptake before and after radiotherapy may be useful for identifying patients requiring more aggressive treatment.

Comparison of the efficacy and safety of tramadol/acetaminophen combination therapy and gabapentin in the treatment of painful diabetic neuropathy.

AIMS: This study compared the efficacy and safety of tramadol/acetaminophen (T/A) and gabapentin in the management of painful diabetic neuropathy. METHODS: An open, randomized, comparative study was conducted. Subjects with painful symmetric neuropathy in the lower limbs and mean pain-intensity score > or = 4 on a numeric rating scale were eligible. Subjects were randomized to receive either tramadol (37.5 mg)/acetaminophen (325 mg) or gabapentin (300 mg) for 6 weeks. After 2 weeks of the titration period (1200 mg/day for gabapentin and three tablets/day for T/A), the doses were maintained if the pain was relieved. The primary efficacy outcome was a reduction in pain intensity. Secondary measures evaluated a pain relief scale, a Brief Pain Inventory, a 36-item Short Form Health Survey, average pain intensity and sleep disturbance. RESULTS: One hundred and sixty-three subjects (T/A 79; gabapentin 84) were included. At the final visit, the mean doses were 1575 mg/day for gabapentin and 4.22 tablets/day for T/A. Both groups were similar in terms of baseline pain intensity (mean intensity: T/A 6.7 +/- 1.6; gabapentin 6.3 +/- 1.6, P = 0.168). At the final visit, the mean reductions in pain intensity were similar in both groups (T/A -3.1 +/- 2.0; gabapentin -2.7 +/- 2.1, P = 0.744). Both groups had similar improvements in every Short Form Health Survey category and Brief Pain Inventory subcategory, and in the mean pain relief scores. CONCLUSION: This study suggests that the T/A combination treatment is as effective as gabapentin in the treatment of painful diabetic neuropathy in patients with Type 2 diabetes.

Valsartan increases circulating adiponectin levels without changing HOMA-IR in patients with type 2 diabetes mellitus and hypertension.

Evaluating increasing circulating adiponectin levels is becoming an important strategy in the prevention of diabetes mellitus and cardiovascular events. This study was designed to investigate the effect of the angiotensin II receptor blocker valsartan on blood adiponectin levels and insulin sensitivity in patients with type 2 diabetes and mild-to-moderate hypertension. A total of 91 Korean patients were treated with 80 mg/day valsartan for 4 weeks followed by 160 mg/day for a further 8 weeks. Blood pressure, adiponectin levels and metabolic parameters were measured before and after treatment. The homeostasis model assessment of insulin resistance (HOMA-IR) was calculated as an insulin sensitivity index. Valsartan significantly decreased mean blood pressure and increased circulating adiponectin levels. There were no differences in metabolic parameters, including HOMA-IR, glycosylated haemoglobin and lipid levels before and after treatment. These results indicated that valsartan increases circulating adiponectin levels, but does not change insulin sensitivity in patients with type 2 diabetes and mild-to-moderate hypertension.

Impact of static biocarriers on the microbial community, nitrogen removal and membrane fouling in submerged membrane bioreactor at different COD:N ratios.

The polyvinyl formal (PVFM) biocarrier addition in a membrane bioreactor (MBR) was evaluated at high and low carbon/nitrogen (C/N) ratio of 20.0 and 6.7. Results indicated that static biocarrier addition could enrich nitrification and denitrification bacteria, dominating by Tauera, Amaricoccus and Nitrosospira at the genus level and slightly improved the total nitrogen removal even at a low C/N ratio. The bulk sludge characteristics (such as bigger particle size, lower SMP, lower SMP P/C) were also significantly changed in the hybrid MBR (HMBR), leading to a more sustainable membrane operation. The biocarrier addition also reduced the relative abundance of Sphingobacterials_unclassified, Ohtaekwangia and Rhodocyclaceae_unclassified at the genus level, indicating less membrane fouling in the HMBR. Consequently, HMBR with static PVFM addition could partially overcome the drawback of low C/N ratio for total nitrogen removal and membrane fouling control, providing a more resilient MBR to the undesirable environment such as low C/N ratio.

Involvement of putrescine in osmotic stress-induced ABA signaling in leaves of wheat seedlings.

To elucidate one mechanism by which putrescine (Put) functions in plant signaling under osmotic stress, Put and ABA contents, and plasma membrane-NADPH oxidase (PM-NOX) activity were detected in wheat seedling leaves. Under osmotic stress, ABA and Put contents, PM-NOX activity, and PM-NOX-dependent O2.- production all increased. The inhibitor tungstate (T) of ABA bio-synthesis reduced the increases in ABA and Put contents under osmotic stress. The inhibitor D-arginine (D-Arg) of Put bio-synthesis didn't reduce osmotic-induced increase of ABA, but it inhibited the increases of PM-NOX activity and O2 . - production, and the inhibitory effects were reversed by exogenous Put. These findings suggested that ABA might regulate Put biosynthesis, and Put might regulate PM-NOX activity. Treatments with three inhibitors imidazole (I), diphenylene iodonium (DPI) and pyridine (P) of PM-NOX reduced significantly not only O2 . - production, but also the stress-induced increase of Put content, which indicated that O2 . - production might regulate Put biosynthesis. Treatments with EGTA (Ca2+ chelator), La3+ and verapamil (V) (Ca2+ channel blockers) reduced significantly the stress-induced increase of Put content, which suggested that Ca2+ might regulate Put biosynthesis. With these findings, it could be concluded that Put was involved in ABA signaling induced by osmotic stress via regulating PM-NOX activity in wheat seedling leaves.

MiRNA-485-5p, inhibits esophageal cancer cells proliferation and invasion by down-regulating O-linked N-acetylglucosamine transferase.

OBJECTIVE: Previous reports suggest that miRNA-485-5p is dysregulated and contributes to tumorigenesis in some cancer types. Nevertheless, the biological role of miRNA-485-5p in esophageal cancer (EC) is not well understood. Additionally, we found that the expression of miR-485-5p in EC tissues was aberrant. PATIENTS AND METHODS: Quantitative RT-PCR (qRT-PCR) was used to demonstrate the expression of miRNA-485-5p in EC cell lines. Cell counting kit-8 (CCK-8) assay and transwell assay indicated that miRNA-485-5p overexpression inhibited cell proliferation, migration, and invasion in EC cell lines. Additionally, Western blotting, dual-luciferase reporter assay, and rescue assay predicted that O-linked N-acetylglucosamine transferase (OGT) was a direct target of miRNA-485-5p. Moreover, we showed that miRNA-485-5p regulated EC tumorigenesis by down-regulating OGT expression in vitro and in vivo. RESULTS: The upregulation of miR-485-5p (fold change = 44 and 26 in ECA109 and TE-1, respectively; p<0.001) was showed by qRT-PCR. Compared with the control groups, the expression miR-485-5p significantly suppressed the proliferation, migration, and invasion of EC cells. The bioinformatic analysis predicted that the 3' untranslated region (UTR) of OGT contains one miR-485-5p target sequences. Western blotting and dual-luciferase reporter assay showed that activation of OGT 3'UTR was increased by co-transfection with miR-485-5p. Finally, CCK-8 assay predicted that the rescue effects of OGT expression on miR-485-5p induced inhibition of cell growth and tumor weight in Eca109 and TE1 cells. CONCLUSIONS: Our results suggest that miRNA-485-5p is a suppressor of EC tumorigenesis and could serve as a novel candidate for therapeutic applications in EC treatment.

Risk factors of peripheral arterial disease and relationship between low ankle brachial index and mortality from all-cause and cardiovascular disease in Chinese patients with hypertension.

The aim of this study was to evaluate the risk factors of peripheral arterial disease (PAD) and the relationship between ankle brachial index (ABI) and mortality from all-cause and cardiovascular disease (CVD) in Chinese patients with hypertension. The ABI cohort Study was designed to investigate risk factors of PAD and the relationship between ABI and mortality from all-cause and CVD in Chinese patients. ABI was identified at baseline by measuring systolic pressure at bilateral brachial and tibial arteries. Mortality surveillance was completed from November 2005 to January 2006. Among 3047 participants with hypertension at baseline, 839 (27.5%) were in the low-ABI group. Older age, female gender, higher serum level of triglycerides, lower serum level of high-density lipoprotein, a history of diabetes and a history of smoking were associated with low ABI. During the 13-month follow-up, there were 252 deaths, of which 100 died of CVD. Low ABI was associated with mortality from all-cause and CVD, whose adjusted relative risk was 1.619 (95% confidence interval 1.190-2.203) and 2.454 (1.531-3.933), respectively, in Cox regression models. The survival rate was significantly lower in the low-ABI group than in the normal-ABI group. This study demonstrated that low ABI was independently associated with a high risk of all-cause and CVD mortality in Chinese patients with hypertension. ABI should be promoted as an ideal tool to predict mortality in diabetic patients.

Comparison of the Kato-Katz technique, hatching test and indirect hemagglutination assay (IHA) for the diagnosis of Schistosoma japonicum infection in China.

The Kato-Katz technique (duplicate 41.7 mg fecal smears), hatching test and indirect hemagglutination assay (IHA) were compared for their ability to detect human Schistosoma japonicum infection in two endemic villages (Zhonjiang and Zhuxi) in rural China. The hatching test (using a nylon bag, and based on about 30 g of feces) and IHA are conventional Chinese diagnostic methods. In both villages, the trends of prevalences with age and sex were comparable for the different methods. In Zhuxi, Kato-Katz examinations of stools from 7 different days and hatching were available, which could be used as a reliable gold standard. This resulted for IHA in a sensitivity of 80% and a specificity of 48%. The sensitivity of the Kato-Katz technique using one stool specimen was 68%, twice that of hatching (33%). In Zhonjiang, however, hatching resulted in more positive cases than Kato-Katz (prevalence 31% vs. 24%). Apparently, the result of the hatching test depends on environmental factors such as temperature and water quality. Although imperfect, Kato-Katz is recommended out of the three evaluated techniques as the method of choice for large-scale screening of S. japonicum. Hatching is much more tedious, provides inconsistent and only qualitative results, and is not much more sensitive than Kato-Katz. Its poor specificity makes IHA unsuitable for individual screening, but it may be more effective for community diagnosis.
