"Latar Belakang: Post-acute sequelae of COVID-19 (PASC) atau long covid merupakan kondisi dengan gejala jangka panjang yang dialami pasien yang telah pulih pasca infeksi COVID-19 yang bervariasi selama beberapa minggu hingga lebih dari 6 bulan. Kondisi ini dilaporkan terjadi pada 7-91% pasien dengan pasca infeksi akut SARS-CoV-2. Beberapa mekanisme diajukan yang berkontribusi terhadap patogenesis PASC gejala gastrointestinal diajukan di antaranya persistensi virus, disbiosis mikrobial, dan perubahan interaksi neuroimun. Saat ini pandemi COVID-19 sudah dinyatakan sebagai endemi di Indonesia dengan menurunnya jumlah pasien dan pelonggaran protokol kesehatan. Sehingga pada penelitian ini fokus terhadap gejala pasca COVID-19 khususnya gejala gastrointestinal (GI) dengan faktor-faktor yang memengaruhinya.Background: Post-acute sequelae of COVID-19 (PASC), also known as long COVID, is a condition characterized by long-term symptoms experienced by patients who have recovered from a COVID-19 infection, lasting for several weeks to over 6 months. This condition has been reported to occur in 7-91% of patients following acute SARS-CoV-2 infection. Several proposed mechanisms contribute to the pathogenesis of PASC gastrointestinal symptoms, including persistent viral presence, microbial dysbiosis, and altered neuroimmune interactions. Currently, the COVID-19 pandemic is declared as endemic in Indonesia with decreasing numbers of patients. Therefore, this study focuses on post-COVID-19 symptoms, specifically GI symptoms, and the factors influencing them.Objective: To determine the clinical profile of post-COVID-19 gastrointestinal outcomes and the associated factors (age, gender, non-gastrointestinal comorbidities, vaccination status of COVID-19, severity of COVID-19, comorbidities of gastrointestinal diseases, history of COVID-19 complications, nasopharyngeal swab CT-value, neutrophil-to-lymphocyte ratio, SGOT, and SGPT).Methods: This prospective cohort study included 134 subjects diagnosed with confirmed COVID-19 based on nasopharyngeal PCR swab, who received outpatient and inpatient care at RSUPN dr. Cipto Mangunkusumo from October 2022 to March 2023. Statistical analysis was performed using SPSS version 25, with a significance level of p<0.05.Results: Out of 134 study subjects, subjects experienced PASC gastrointestinal symptoms in the first month, and 70 subjects in the third month. The most common manifestations of PASC gastrointestinal symptoms in the first month were constipation and nausea/vomiting in 21 (15.7%) and 10 (7.5%) subjects, respectively, while nausea/vomiting was the most common symptom in the third month. Bivariate analysis revealed significant associations between non-gastrointestinal comorbidities (p=0.011) and CT-value ≥25 (p=0.028) as risk factors for PASC gastrointestinal symptoms in the first month, as well as comorbidities (p=0.022) in the third month. Multivariate analysis found that non-gastrointestinal comorbidities had the most significant influence on PASC gastrointestinal symptoms in both the first and third months, with a relative risk (RR) of 1.608 times (95% CI 1.140 – 2.260; p=0.007) and 2.089 times (95% CI 1.093 – 3.990; p=0.014), respectively.Conclusion: There is a significant association between non-gastrointestinal comorbidities and the occurrence of PASC gastrointestinal manifestations in the first and third months, as well as a CT-value of COVID-19 >25.0 and the occurrence of PASC gastrointestinal manifestations in the first month.Tujuan: Mengetahui profil luaran klinis gastrointestinal pasca COVID-19 dan faktor-faktor yang memengaruhi (usia, jenis kelamin, status vaksinasi COVID-19, komorbiditas non-gastrointestinal, derajat COVID-19, komorbiditas penyakit gastrointestinal, riwayat komedikasi COVID-19, CT-value swab nasofaring, neutrophil-to-lymphocyte ratio, SGOT, dan SGPT)Metode: Desain penelitian berupa studi kohort prospektif pada 134 subjek yang didiagnosis terkonfirmasi COVID-19 dari swab PCR nasofaring yang di rawat jalan dan rawat inap RSUPN dr. Cipto Mangunkusumo selama periode Oktober 2022 sampai dengan Maret 2023. Analisis statistik menggunakan SPSS versi 25, nilai p<0.05 menunjukkan kemaknaan secara statistik.Hasil: Sebanyak 134 subjek penelitian, 64 subjek mengalami gejala gastrointestinal PASC pada bulan ke-1 dan 70 subjek pada bulan ke-3. Manifestasi gejala gastrointestinal PASC terbanyak pada bulan ke-1 yaitu konstipasi dan mual-muntah sebanyak 21 (15,7%) subjek dan mual-muntah 10 (7,5%) pada bulan ke-3. Pada analisis bivariat terdapat hubungan yang bermakna pada subjek dengan riwayat komorbitas (p=0,011) dan CT-value ≥25 (p=0,028) sebagai faktor risiko gejala gastrointestinal PASC pada bulan ke-1 serta subjek dengan komorbiditas non-gastrointestinal (p=0,022) pada bulan ke-3. Analisis multivariat menemukan riwayat komorbiditas non-gastrointestinal paling memengaruhi gejala gastrointestinal PASC pada bulan ke-1 dan ke-3 dengan relative risk (RR) 1,608 kali (IK 95% 1,140 – 2,260; p= 0,007) dan 2,089 kali (IK 95% 1,093– 3,990; p = 0,014).Kesimpulan: Terdapat pengaruh yang signifikan antara riwayat komorbiditas non-gastrointestinal terhadap kejadian manifestasi gastrointestinal PASC bulan ke-1 dan ke-3 serta nilai CT-value COVID-19 >25,0 terhadap kejadian manifestasi gastrointestinal PASC pada bulan ke-1.

Background: Surgical site infection (SSI) after gastrointestinal surgery can affect mortality and morbidity of the patients. Risk factors are needed to prevent and decrease number of SSI. This study investigated the pre-operative and intra-operative risk factors of gastrointestinal surgeries and incidence of SSI.

Methods: A retrospective audit analysis of age, nutritional status, pre-operative length of stay, length of surgery, type of surgery, degree of contamination in adult gastrointestinal surgery patients at Cipto Mangunkusumo General Hospital was conducted from the medical records from 2012 to 2016. Outcomes consisted of incidence and potential univariate risk factors were determined to investigate the independent associated factors using multivariate logistic regression.

Results: The incidence of SSI in four years is 3.4% among 4,357 gastrointestinal surgeries with 86.4% of surgical site infection appears in contaminated wound operations. Our study included 116 subjects. From univariate analysis between SSI as dependent factors and the the risks factors, age (p=0,2), pre operative length of stay (p=0,06), length of surgery (p=0,1), and degree of contamination (p=0,003) have correlative association with SSI. The risk factor with surgical site infection is surgical wound contamination (OR=1.233, p=0.011) and independent from other risk factors.

Conclusions: From pre operative and intra operative risk factors there are four factors which have correlation with SSI, there are age, pre operative length of stay, length of surgery, and degree of contamination. Degree of contamination is the significant risk factors for SSI."

"Latar belakang: Infeksi saluran cerna dengan manifestasi klinis berupa diare merupakan penyakit infeksi dengan kesakitan dan kematian yang tinggi terutama di negara-negara yang sedang berkembang. Diare menimbulkan kematian terutama pada bayi baru lahir di bawah 1 tahun. Penanganan telah ditingkatkan secara terus menerus, namun demikian kemajuan dalam diagnosis maupun pengobatan tidak terjangkau oleh negara-negara yang sedang berkembang. Salah satu penyebab infeksi saluran cerna adalah bakteri. Oleh karenanya dengan mengetahui bakteri penyebab serta pola resistensi bakteri terhadap antibiotik dapat menunjang penatalaksanaan penyakit ini. Studi ini dilakukan untuk mengetahui berbagai jenis mikroba yang diisolasi dari saluran cerna serta pola resistensinya terhadap beberapa antibiotik.Metode: Spesimen berupa tinja, usap dubur atau anus yang diterima oleh Laboratorium Mikrobiologi FKUI selama 2005- 2008. Isolasi, identifi kasi kepekaan dan uji antibiotik dikerjakan sesuai prosedur standar yang berlaku. Interpretasi hasil uji kepekaan menggunaan panduan NCCLS/CLSI. Data dianalisis menggunakan WHOnet versi 5.3.Hasil: Diperoleh 28 isolat Escherichia coli patogen, 1 isolat Salmonella paratyphi A, dan 4 isolat ragi yang diisolasi dari tinja dan swab dubur penderita. Walaupun Escherichia coli patogen masih peka terhadap beberapa antibiotik, namun kepekaannya menurun terhadap amoxicillin, sulbenicillin, ticarcillin dan trimethoprim/rulfamethoxazole.Kesimpulan: Escherichia coli patogen merupakan bakteri terbanyak yang berhasil diisolasi dari tinja/usap dubur. Bakteri ini telah menunjukkan penurunan kepekaan terhadap beberapa antibiotik yang sering digunakan untuk mengobati infeksi saluran cerna. (Med J Indones 2011; 20:105-8).

AbstractBackground: Digestive tract infection with clinical manifestation of diarrhea is an infectious disease that has the highest morbidity and mortality rate, especially in developing countries. Diarrhea causes mortality mostly in infants under one year old. Improvement in management is done continuously, but advances in diagnosis and therapy cannot be reached by developing countries. One of the etiological agents causing infection of digestive tract is bacteria. Therefore, knowledge of bacteria that cause gastrointestinal infection and their resistance patterns may support the management of this disease. The aim of this study was to examine microbes that were isolated from the digestive tract and their resistance patterns against antibiotics.Methods: Samples (stool, rectal/anal swab) were collected from the Clinical Microbiology Laboratory, FKUI during 2005-2008. Isolation, identifi cation and sensitivity test were conducted according to standard laboratory procedures. Interpretation of sensitivity test was done according to NCCLS/CLSI guidance. Data was analyzed using WHOnet version 5.3.Results: We found 28 isolates of pathogenic Escherichia coli, 1 isolate of S. paratyphi A and 4 isolates of yeasts. Pathogenic Escherichia coli were still sensitive against some antibiotics, but the sensitivity was reduced against amoxicillin, sulbenicillin, ticarcillin and trimethoprim/sulfamethoxazole.Conclusion: The most predominant gastrointestinal tract infection causing microbes was pathogenic Escherichia coli. These bacteria showed decrease sensitivity against some antibiotics commonly used to treat patients with gastrointestinal tract infection. (Med J Indones 2011; 20:105-8)"

"Pendahuluan: COVID-19 telah dilaporkan menyebabkan berbagai gejala, termasuk gejala pernapasan dan gejala gastrointestinal seperti mual, muntah, dan diare. Standar emas untuk pengujian COVID-19 adalah RT-PCR menggunakan koleksi swab nasofaring. Namun, beberapa penelitian menunjukkan bahwa pengambilan swab nasofaring memiliki beberapa keterbatasan, terutama untuk mendeteksi gejala gastrointestinal. Salah satu variabel dalam pengujian RT-PCR adalah Nilai CT yang diketahui dapat meningkatkan spesifisitas pengujian. Namun, belum ada penelitian yang menghubungkan Nilai CT pasien dengan pengambilan sampel swab anal dengan gejala gastrointestinal terkait COVID-19. Metode: Penelitian ini menggunakan desain penelitian analitik, khususnya penelitian potong lintang. Data sekunder diperoleh dan diolah yang berisi data pribadi, pekerjaan, dan hasil CT Value. Analisis lebih lanjut dilakukan pada hubungan antara gejala gastrointestinal dan tingkat Nilai CT pada swab anal. Hasil: Distribusi tingkat Nilai CT responden berdasarkan cut off >25 untuk tinggi, dan <25 untuk rendah dan sedang. Dari 37 subjek, 1 orang (2,7%) memiliki Nilai CT rendah dan 36 pasien memiliki Nilai CT tinggi. Distribusi gejala subjek didapatkan 15 pasien (40,5%) tidak mengalami gejala gastrointestinal dan sebanyak 22 pasien (59,5%) mengalami gejala gastrointestinal. Gejala gastrointestinal umum yang dilaporkan pada pasien meliputi: mual (54,1%), muntah (18,9%), sakit perut (16,2%) dan diare (13,5%). Namun, tidak ada hubungan yang signifikan (p>0,05) antara Nilai CT pada pengambilan anal swab dengan gejala gastrointestinal pada pasien COVID-19. Kesimpulan: Hubungan antara Nilai CT pada pengambilan anal swab dengan gejala gastrointestinal pada pasien COVID-19 tidak menunjukkan hubungan yang signifikan. Penelitian lebih lanjut tentang faktor risiko yang mempengaruhi hasil nilai CT direkomendasikan.

Introduction: COVID-19 has been reported to cause a range of symptoms, including respiratory symptoms and gastrointestinal symptoms such as nausea, vomiting, and diarrhea. The gold standard for COVID-19 testing is RT-PCR using nasopharyngeal swab collection. However, several studies have shown that taking nasopharyngeal swabs have some limitation, particularly to detect gastrointestinal symptoms. One of the variables in RT-PCR testing is CT Value, which known can increase specifity of the test. However, there has been no study linking the CT Value of patients with anal swab sampling with COVID-19 related gastrointestinal symptoms. Methods: This study used an analytical research design, particularly a cross-sectional study. Secondary data were obtained and processed which contained personal data, work, and CT Value results. Further analysis was conducted on the relationship between gastrointestinal symptoms and the level of CT Value on anal swabs. Result: The distribution of respondents' CT Value levels were based on a cut off of >25 for high, and <25 for low and moderate. From 37 subjects, 1 person (2.7%) had a low CT Value and 36 patients had a high CT Value. The distribution of the subject's symptoms found 15 patients (40.5%) had no gastrointestinal symptoms and as many as 22 patients (59.5%) had gastrointestinal symptoms. Common gastrointestinal symptoms reported in patients include: nausea (54.1%), vomiting (18.9%), abdominal pain (16.2%) and diarrhea (13.5%). However, there was no significant relationship (p>0.05) between CT Value in anal swab taking and gastrointestinal symptoms in COVID-19 patients. Conclusion: The association between CT Value in anal swab taking and gastrointestinal symptoms in COVID-19 patients did not show a significant relationship. Further research on risk factors affecting the CT value results are recommended"

"The gastrointestinal track provides one of the distinct systems where multiple malignancies, including adenocarcinoma of the pancreas, esophagus and colon are each associated with obesity. The focus on possible dietary contribution as well as the role of exercise in prevention and therapy is presented in both animal model and patient based studies. Special focus is provided also on the role of genetic mutations and inflammatory pathways as drivers of these obesity related gastrointestinal malignancies. "
